Time to get back at er.

I decided just for cosmetics to paint the dust collection holes before the formica went down, had the paint wouldn’t of made a special trip to town for it. lol

Testing the rails and roller bearing for clearance and mounting option.

Came up with a box idea to fit between the main posts, gives me the option to move the rails up and down, in and out and tilt, once everything is set 4 – 4 inch heavy torx washer head screws on both ends of the box should hold everything in place quite nicely and can easily be readjusted if necessary.

Added a couple oak pieces just above and below the roller bearings. just didn’t like the way it looked with the open bearing, lol form and function. :)

Extremely happy right now, built the two bearing support boards for the gantry and clamped a board across the top to see how it would roll and I think I need to give myself a pat on the back. lol that thing rolls so smooth its unbelievable with no slop that I can tell whatsoever. Can you tell I’m smiling. :)

Here is a close up of the bottom gantry support with the bearings, Drilled holes in the bottom and tapped for a standard 3/8th inch thread. the hole goes all the way in the bearing bolt hole which is slotted up and down an extra 5/16 inch.
A 5/16×1-1/2 inch spring was loaded into the hole before the bolt threaded in, this is not to hold constant pressure on the bearing but to give all the bearing equal pressure before tightening, plus if the track ever wears a quick loosen and retighten of the nuts and all slop will be removed.

And just a couple of quick shots of both ends. Can’t wait to start constructing the gantry for real. :-)

Mama thinks I should be spending more time building her kitchen and less time on the CNC. Hmmmm BOOOO. lol Just kidding she is worth it.

My next entry might take a little longer unless I burn more midnight oil. :0

Hey thanks for stopping by and having a look! Suggestion, comments and questions are welcome

Cheers – Jeff

P. S. I’m really having fun with this!!

Edit:

A Pic to help answer a question. :)

As the aluminum track wear’s, the roller bearings will need to be adjusted.
As I tried to explain in pic 20 but didn’t do a very good job :( the bottom bearing bolt hole is slotted for up and down movement, a bolt and spring are inserted from the bottom to add a fair amount of pressure to seat the bottom bearing to the track, then the bearing nut is tightened.

When the track starts to wear a quick loosen of the bearing nut and the spring will push the bearing tight up against the track again and then just re-tighten the bearing bolt again.

Hope that makes sense. lol

Getting some of the ruff components spruced up a little while waiting for some fat washer and longer bolts.

Large Pic

Trying to keep the tolerances to minimum, only about a 1/16” between the gantry carrier and the guild rail.

Have a great day!

O man, I like this blog. You are using V bearings, and have to use a lot and they are not cheap. Can you mention also the cost in your blog?

Hey Dutchy, well yes I can, purchased the bearings off eBay for just under $5 each, figured it would take about 16 so I ordered 20 equaling about $98 and change free shipping, not real bad but the small items can add up pretty fast.
The big ticket items I have yet to order but hopefully I can stay under a grand. will post all the prices and links if I remember. :-)


Impressive build.

Thank you Mike!

Appreciate you guys stopping by and commenting!

Following along…. dreaming of my own (distant) future CNC build.
I’ve done a lot of research & learning, over on www.cnczone.com.
Given my proclivity towards procrastination….
It may be the next millennium before I finish or even start my build.

BTW: Nice progress…. Carry on!!!

-- Randy-- I may not be good...but I am slow! If good things come to those who wait.... Why is procrastination a bad thing?

That was a good deal Jeff. 16 V bearings for under 100 box. What is the measerment of the bearing. I can,t find them here for that price. How will you do realignment after the aluminium gliding units are ingrained.

I,m looking forward how you will do the CNC control.

Succes Jeff.

PS. When your router is finished you can make a beautiful kitchen with it.

Randy, there is not time like the present. lol I think you should start one now and post your progress ;)
I see you like making bowls and pens, this would be a great addition to your workshop! Just go for it.

Thanks for stopping by!

Dutchy…..buddy, Guess I didn’t do a very good job in explaining the track wear issue in pic 20 so I edited the post and added and extra pic and explanation, hope it makes sense. :)

Here is a link you the bearing I purchased, they do ship world wide and I purchase 20 of them for just under a hundred bucks.

The controller and stepper motors are a package deal.

Just plug and play, the wires will not be long enough for this application plus I want you have flush mount plugs somewhere in the area of the stepper motors so they just plug in, this way some day if I upgrade they will be easy to disconnect. Something like this or this

Hey Jeff, nice build so far.

When I used Vbearings on angle iron, I split the rails into two sections; an upper and a lower. This allowed me to adjust both sides and tops and bottoms independently. Just a thought.

Didn’t get a lot done since the last post but managed to do some cosmetic work to the rail (added two pics) plus after hours of deliberation between the 3 of us, me, myself, and I, finally nailed down the gantry design.

Won’t be the simple of tasks to get it right the first time, but I’m up to the challenge. lol I will post the mistakes to, there should be lots of those. :)
