T-slot comes home

I've been planning a 4-axis machine in my head for more than a decade now.
Every time I go to put it on paper, I get another idea and end up trashing all my notes.

I have a pretty good idea what I want and the materials I can acquire on the cheap will dictate most of what ends up becoming my completed machine.

I want to be able to do 3 axis machining on a small basis, but also a 4th rotary axis for doing and carving on turnings and 3-D objects.

I've found a lot of good componants and they've come down in price even since last year.
This T-slot is from an old test bench that my Father had gotten and wasn't using. He gave it to me as a birthday gift. What he really gave me, was the birth of my new machine. I figure I've got just enough here to make up the framework of a decent hobby machine.

There's no real budget sitting around for this project, so I'll have to acquire peices out of my monthly budget.
This will be a slow going project. If I finish it within the next two years, I'll be pretty satisfied. For now, this is what I've got.

I spent a couple hours last night stripping this down and cleaning it up. It sat outside for some time and a lot of the bolts and nuts were rusted. They're all now soaking in oil in a #10 can to clean them up.

T-slot is like the grown man's erector set. This stuff is cool. This 2" X 2" stuff is way more rigid than I thought it would be. I've decided to do a double rail framework to make it even more rigid. It should work fairly well I think.

That's it for now. Stay tuned. Take notes. Thanks for reading along!

Hey DS, this will be fun.

Building a machine like this is such a mind consumer. I still keep getting the bug to build another, but too much stuff is in the way. I will watch with delight what a craftsman such as yourself will create.

You probably know, but the ebay 8020 store is a great and cheap way to get the missing extrusions for this.

Thanks Steve!
It's seeing the machines that folks like yourself have made that has emboldened me to take the plunge.

I have a short list of things to buy as soon as I can scrape up about $600 with no where else to go. I suspect it won't be the last short list.

You can't go wrong using the Tslot or 80/20 extrusions! They are strong, versitile, and better than any other solution including custom machined parts.
When I was working I built several production tools using Tslot material and the only dissapointment I had was using the linear slides but then my expectations were too high. They did provide a good smooth movement but the lateral play dissapointed me.

Are you going to use linear bearings?
Stepper or servos?
PLC (would be rather novel), Laguna uses that) or PC control?

Have you looked at the Legacy CNC and their 1/2 axis?
Legacy CNC
Kind of a partial solution to another dimension.

Too nosey, too many question!

I'm looking at using stepper motors. Servers would we terrific, but I am going to try this on the cheap for this machine.

The controller I am looking at can handle four 3.5A stepper motors and I'm going to max that out. It is a nice self-contained unit that can be driven from the on-board keypad and display (Think manual pulse generator), or, it can be fed by a PC via a parallel port interface.

There is a rotary axis with a 3 jaw chuck and a smaller NEMA23 motor that uses pulleys to gear it down. It looks like it will fit the bill nicely for about $200.

The main conflict for me is the spindle. I really, really, really want an ATC spindle. But, the cheapest one I've seen is $2500.00 I can get a non-ATC spindle for under $500 so there is a huge difference. I keep trying to think how to make an ATC and adapt it to a non-ATC spindle, but, no joy on that front yet.

For bearings, if I can find some used THK linear bearings that would be awesome. T-slot systems has a ball bearing slider made for thier products, but I have no idea how suitable they would be for the X,Y & Z axis functions.

The tailstock on the 4th axis will use the t-slot nylon bushings with a locking brake to adjust for stock length. I still need to work out a rack and pinion setup for the X axis and am still entertaining other solutions in that regard.

When I'm done, my machine should resemble the Legacy machine quite a bit I suspect.

All good questions. I don't mind at all.

YES!

This will be very interesting to watch…

That's an expensive bunch of extruded aluminum there… good stuff!

Thank you.

Auto Tool Change - huh, it seems like that would not be the "main conflict" yet. You could always add it later. (?) The price difference is amazing.

But hey, I guess that shows that this is not going to be just a throw together machine.

I love it,

The conflict, for me, is between wanting the ATC capability and not wanting to spend that much money.
You are right though, I can delay that decision for quite some time.

Who knows? I might fall into some extra dough next year.

In any case, I am designing a space above and behind the rotary chuck for the tool holders. I should be able to fit 5 or 6 of them there.

So, last night I went out and started assembling the framework.

I decided to use the corner brackets on the ends of the rails to make the corner joints because I thought they would look cooler that way. The rails have holes for this purpose, but, to my slight dismay, they are not tapped. So I spent about an hour tapping the holes with a makeshift tap before I could put anything together.

By the time I called it a night, I got one end of the unit assembled and I have a good vision of how it will come together. ( I remember kid's erector sets being easier than this.)

I'm going to take pictures this weekend as I hope to get the rest of it put together.

BTW, my homemade tap was a bolt which I cut across the threads with my dremel tool's cutting disk. It worked fair enough, though I think my drill has seen better days driving the tap under lots of torque. I did get a blister on the knuckle of my thumb though-soft hands being what they are. (I cut wood with my computer mouse after all.)

I take it you are not using the 80/20/Tslot joint connectors! Those connectors are really strong.

Yes, I am using the connectors where they apply.

The main reason is the asthetic of it all. I didn't want open ended rails hanging out in the air.
It actually looks pretty good this way and it is also really strong.

Pictures will follow on Monday.

Yup, this stuff I'd strong!

There are end cap cover available that just snap into the extrusions. They do not require any hardware.

There are also groove covers available. These are useful for keeping dirt and/or sawdust out of unused section of the extrusions.

When I was contemplating my own build I was considering an enclosed cutting area with sliding Plexiglas doors for access because I had enough snap in sliding door tracks for two 4' x 8' tables.

I am sure you can find these on eBay if you can wade through the over 6,200 items just for 80/20 extrusions. I am lucky as the local Tslot distributer and I are on friendly terms and they are less that 8 miles from my house.

Using these extrusions opens a whole new world of possibilities!

I've wanted to do this for a long time. My main hobby was electronics about 5 or 6 years ago. Up until about 3 months ago I hadn't touched it since that time. Unfortunately for my woodworking I haven't done anything but electronics for about 3 months, so now I've gotten the bug again.

Due to an unfortunate set of circumstances at the plant I am now retired at 62 years old. I plan on trying to earn whatever the SS people will allow me to with a combination of my hobby woodworking, buying and selling on Ebay, and some websites that I have in my mind. Web sites are also a hobby of mine. I have too many hobbies actually.

I am seriously thinking of buying a laser engraving machine and a small 2ft by 4 ft commercial CNC router and they're both Jim Dandies. Surely with these machines I will be able to make some extra money with my woodworking. However, for some crazy reason I still want to build a CNC for myself. I'm hoping also to get a small milling machine and lathe since I no longer have my machine shop at the plant. So, I guess you could say I'm going to have sort of a busy retirement.

I wish you the best of luck on this project and I'll be checking it out to see how you are coming on it. May you be happy in your work.

I want to be able to do 3 axis machining on a small basis, but also a 4th rotary axis for doing and carving on turnings and 3-D objects.

I've found a lot of good componants and they've come down in price even since last year.
This T-slot is from an old test bench that my Father had gotten and wasn't using. He gave it to me as a birthday gift. What he really gave me, was the birth of my new machine. I figure I've got just enough here to make up the framework of a decent hobby machine.

There's no real budget sitting around for this project, so I'll have to acquire peices out of my monthly budget.
This will be a slow going project. If I finish it within the next two years, I'll be pretty satisfied. For now, this is what I've got.

I spent a couple hours last night stripping this down and cleaning it up. It sat outside for some time and a lot of the bolts and nuts were rusted. They're all now soaking in oil in a #10 can to clean them up.

T-slot is like the grown man's erector set. This stuff is cool. This 2" X 2" stuff is way more rigid than I thought it would be. I've decided to do a double rail framework to make it even more rigid. It should work fairly well I think.

That's it for now. Stay tuned. Take notes. Thanks for reading along!
I wonder how many LJ have this stuff stashed away?

Maybe we should setup a swap forum!

Following along. . . .
I've programmed and run many CNC machines (Routers, Mills, Lathes) but always wanted my own to play with.
Looking forward to following along.

I'm on board for the ride. This should be cool.
And I know about hurry up and wait for parts.
To me that gives you a lot of time to think it out.
I am wanting to build a work bench and I have pictures of benches plastered all over my office wall. I will just sit and think of what features I want and will use.
Good luck.

Putting it together - a start, anyways.

Well, as promised, here are some more pics of the process.

Before;
Wood Gas Bicycle part Metal Font


First thing I had to do was tap the end screw holes for the corner brackets. I could have used these with the t-slot connectors and not had to tap anything, but I wanted the brackets to do double-duty as end caps too.

I didn't have an appropriate tap, so I used my dremel tool to cut a groove across the threads of a screw, being careful to leave a good cutting edge on the leading edge of the threads.

With a little 3-in-1 oil and my power drill, it worked out nicely.

After;
Wood Automotive tire Gas Bicycle part Auto part


It didn't take too long to get it put together to this point. I have about 2 1/2 hours into it so far.

It's beginning to take shape;
Wood Bumper Rectangle Automotive exterior Gas


I'm pretty sure I will need to add some sort of levelling legs underneath it in order to set it level and true.
Right now the thing has a twist in it and is put together mostly to solidify the vision I have in my head for this.
The leveling legs will likely add another 4" to 6" in height to this which will put it right about where it should be.

I won't bother to true it up until that part is done.

There will be another frame inset inside this one that will hold the 4th axis motor and tailstock.
It will be hinged at the head and have an adjustable height on the tail end-probably with some all thread. (Details pending, of course) This will allow for tapered work. (The infamous pseudo-5th axis.)

The side panels will probably be filled in for rigidity, but I want to be sure that the bearings and pinon gears will have the required room for mounting before I do that part.

The current overall size is 28"W X 68"L X 28"H

Thanks for following along. Stay tuned.

I have a dining table project coming up which may provide funds to buy the next batch of parts. That could be as soon as Thanksgiving. We'll see how it goes.

How lovely are the feet!

Okay, so I finally had to spend some money on this project…

I knew I needed a good foundation on this beast of a machine I am going to build, so I went about looking for a suitable set of leveler feet for it.
What I decided on turned out to be fairly cost effective and appropriately substantial to handle the anticipated load I'm going to put on this thing.

For $26.99 I found a set of four Billiard table legs on Amazon which looked like they would mount up perfectly to my machine.
Composite material Circle Metal Fashion accessory Steel

When compared to the furniture levelers, there was no comparison. 6" diameter cast metal feet with a chrome finish-Nice!

Gas Bumper Automotive exterior Grille Aluminium

First thing I had to do was to flip the frame upside down and drill a 1/2" hole through the bottom of the rail.

Machine tool Nickel Rim Gas Wood

I added the T-slot nuts into the rail and screwed the mounting plate to the bottom of the rail. For this I had to shorten the screws a bit as they bottomed out before tightening the plate. That proved to be the most time consuming part as all I had was a cut-off disk in my dremel for the task.

Automotive tire Gas Bandsaws Wood Bumper

The feet threaded right into the mounting plate and they are very secure.

Gas Wood Flooring Aluminium Automotive exterior

Once all four feet were attached I flipped the frame back over.

Voila! It's starting to look like something.
Tire Gas Wood Flooring Wheel

I still need to true up the framework, but that will be a relatively simple task, now that I have adjustable feet for it.

My next big purchase are the THK rails for the main X axis. They are 65" long and cost around $500.00 for the pair. This might seem overkill, but I intend on this thing being very accurate and tight toleranced.

It will be one of many substantial investments into this future CNC machine.
Thanks for following along! Happy Thanksgiving to all!

Good move. Good idea.

Are you planing to add a skin to the sides to prevent racking? I have not ever worked with those extrusions so maybe it's not a problem. (?)

Man, this is fun to watch.

Linear Rails - WOO HOO! - eBay doesn't totally suck after all.

Parallel Wood Ladder Outdoor furniture Shade


Just won these on eBay!

I'll bet most of you gave up on this build!
This will be for the main x-axis which will carry the gantry.

There's enough resources (read money) left to buy the A xis motor, gear head, chuck and tailstock.
After that it's back to the waiting-for-money game. :-(

If only the clerk at the 7-eleven would stop selling me the LOSING lottery tickets this would go faster.

Expected delivery March 27th
(I feel like a proud Papa)

----------------------------------

UPDATE:

Score another one for eBay!

This is a 100:1 planetary gear box with a NEMA 34 Stepper motor.
It will become the drive for my rotary A axis. that takes me from 200 steps per revolution to 20,000 steps per revolution. SWEET! And for the auction price of $72, it can't be beat.

Auto part Cable Wire Fluorescent lamp Electric blue


This should arrive in the next week or so.

Bet you thought I gave up on this...

I decided to widen the machine when I started planning for the y axis.

I was going to have to cut down most rails anyway so I thought I'd rather have the extra capacity.
Also, while I had the entire assembly tore down, I decided to add the maple panels into the frame to rigidize the entire assembly. It has really made a big difference.

Wood Gas Automotive exterior Aluminium Rectangle


The y axis began with the guide bearings and some 2" angle.
I threaded the ends on the 80/20 rails and secured them to the angle. The plan is to add maple panels in these as well. I'll cap these with a top maple panel and attach my horizontal rails to the front.

Wood Machine tool Composite material Automotive exterior Rectangle


The gantry should be fairly rigid when fully assembled.

I've decided to focus more energy this year to completing this machine.
Unfortunately there is less of a budget this year than there was last year. Still, I'm gonna see this through.

Hang in there as it doesn't look much like a CNC at this time.

Isn't that extruded aluminum a delight to have/work with? One of my last projects, before I got laid off/retired, was vision inspection system to inspect the laser assemblies which I built with the 1" size of T slot material including linear slides, a screened PC location, and flat screen monitor. This inspection system was moved into an optical class 1 clean room about 9 months before I left. I really fell in love with the camera I used on that system as it was fast and all parameters were accessible by the PC and the inspection state machine. OOPS got a little off topic

Aren't you concerned about increasing the noise level with all that resonant plywood?

Y axis coming together...

Received the y axis THK rails yesterday-just in time for the weekend.

Plant Hood Automotive tire Wood Car


I was able to mount them and begin assembling the y axis carriage.
As soon as the rack and pinion arrives I'll be able to make the motor mount box and start focusing on the z axis plate.

Wood Wood stain Automotive exterior Gas Hardwood


The y axis rack and pinion gears are stuck in Chicago almost a week already. Not sure what the hold up is.
The cable drag chains arrived today from the east coast with no issues.

The chains themselves came as three separate 1 meter lengths. Opening the links wasn't nearly as difficult as reattaching them. After some trial and error and at least one broken link, I got the two sized chains that I need.

Wood Font Rectangle Auto part Fashion accessory


I bought some 1 1/2" x 1/16" aluminum angle to make the drag chain trays for both the x and y axis and should finish those this weekend. If so, I'll update this post with more photos

In my recent shopping spree, (the money is blown already, btw) I was able to locate a used ISO 25 tool changing spindle, but it was still nearly $3600. That's a little better than the new ones I've been finding for $13500 but both options are still outside my reach.

UPDATED PICS:

Added the y axis cable drag chain tray to the back of the gantry. Decided to hold off on the x axis tray until that rack and pinion is installed.

Looks like you're doing just fine!

Will be interesting to see how it develops and how it works!

Thank you.
