« Part 19: I need to do this one quick. Canoe shed... Part 20 of Upcoming projects and designs. series Part 21: Now that the shop is approaching usefulness again. Thresholds for tile to concrete transition! »

It’s one of those deals… The Sketchup models that I need, don’t exist, or the ones I made aren’t worth a warm bucket of spit.

You see I need to design a pair of flip top tool stands. But I want to guarantee they fit my tools, while using the least amount of floor space possible…

My tool stacker is great, but has some disadvantages that are wearing very thin on me right now… As many of you may or may not remember, I have back problems. The doc and I are working to fix them, okay the doc is fussing, and I am doing the therapy, anyway I digress…

That lifting of the planer, jointer, and bench grinder are a big part of what keeps me from being more productive in the shop. And elsehwere the miter saw sucks up a ton of room, and the mortiser is rarely used. And I want to fix these problem, my solution is, for better or worse, a pair of flip top stands.

One of these stands is to house my Ryobi AP1301 planer, and my Sunhill SM-150B bench top jointer. The other to house my HF 12” SCMS, and HF mortising machine.

My initial attempt at modelling the Sunhill jointer was just to get an idea of scale, and it was sloppy at best.

My next attempt is at least more detailed. I do still need to work on some of the details such as the fence, guard, and switch, but it is coming along nicely…

And of course the planer. The model I started out with was barely sufficient for size, and whomever originally posted it took it down. It honestly stunk that badly. There is a nice model of a DW735 up there though!

Long story short, I am trying to get the models of my tools as accurate as possible, so that I can build the models of the stands and test things like rotation of the head assembly in a virtual environment prior to even buying the lumber for the build… The models that are out there, left me very wanting for something better to insure the accuracy of my builds…

The build of the sander is still in progress, although slow it is going. I have yet to get the shaft into a machine shop, but I at least have the drum assembly well under way. The plugs are in progress, and the drum piece is cut to final length and drilled / counter sunk for the mount holes.

After a painful amount of deliberation, I have opted to go with a 24” drum. I am probably off my rocker here, but the sander overall will be kind of huge, I waned to minimize the hit to the floor space, and would never use anything wider than 24” (he says now…).

All this happening while also continuing with the remodelling… Ugh.

Hold your tongue lad, I can’t even get into the shop, let alone Sketchup.

I have made it a rule that I will not do anything of significance in my off time until I get my programming project done. Now I remember why I quit doing programming in a hobby sense.

But this is a very focused work project that will actually generate money, so it is under a halo. Plus, my keyboard challenged Physicians Assistant really needs it…...a long time friend and employee who merits most anything I can do for him. The structure of the program is well developed and 95% completed. It has gone through a myriad of changes, for it has to be an interface marvel to work properly. But I have to still have to make the content, meaning the medically specific stuff, although I have finally worked out the structure to my satisfaction. Anyone who wants to get into the language end of medicine should first realize that the average physician adds 50,000 words to his vocabulary during training…...we normally use 500 words in ordinary conversation. Fortunately, I have a circumscribed arena to encompass with the templates.

So I haven’t been in the shop in a serious manner for a couple of months, and I fear I have one month to go. But I will be doing some shop stuff down in La Conner for a short week at the end of the month. My comments on LJ’s have been terse and sporadic as evidence of the collateral damage in my life. Got maxed out today, so you are the recipient of an indulgence….....(-:

So…...remember…....it is only the outer dimensions of your object that are important in a flip top design. I have done that somewhere, sometime in my life, in Sketchup, but the specifics escape me. Maybe it was the sawdust control, still not completed for my contractor’s saw, where things have to be enclosed, but allow for the movement of the motor, belt, and associated apparatus. So you don’t have to make a pretty thing, just something with the dimensions at the limits of the object done with accuracy. I did that with my convoluted woodworkers vise installation on my multipurpose bench, as well, but that is a linear, not a rotary problem. Another linear application was my strange table saw switch, that has turned out to be an absolutely delightful and usually unnoticed addition to the shop. It always works, and I don’t think about it.

I have volumes of verbiage to impart here on LJ’s, but it is on hold till I get through the current dominating project….......kinda like your remodelling.

Hope you and family are doing well…....been kinda off the grid to some extent for awhile…...work related. But have followed your stuff closely…....although the drum sander is not something I would ever do…....

Okay, the only important dimensions are the clearances. In other words, don’t build a 22” base if the tool is 24” and so on. Make your flip platform sized to fit the larger of the two tools it will hold. The clearance between the cut out on the back and the tools should be as close as possible without getting silly about it. An inch is fine. All you need to figure that out is a sillouette of both tools. Almost as important is balance. Try to make it as balanced as possible, keeping the center of gravity as close to the pivot as you can, even giving up some clearance if you must, as a balanced unit will be much easier on your back when you flip it.

Make the side uprights as stiff as you can, as this will stabilize the tool when in use. A good way to do this is to make the uprights a narrow set of drawers to hold small accessories, bits, sandpaper etc. Another set of drawers under the flip will make the base sturdy.

Most such stands have both shelves supporting the tools the same size. This has its drawbacks. I prefer to make one tool shelf wider than the other by an inch on each side, then put a support on the uprights one one side of the pivot running all the way from the pivot to the edge of the tool shelf and the same width as the flip assembly is thick. That way, when one tool is on top the shelf rests on top of this support and when the other tool is on top the shelf “rests” against the bottom. Then you only have one end to lock in place to get a really solid placement.

As for the drum sander, if you have a lathe you’re halfway there. The lathe provides the bearings, power and bed. All you need to add is your drum and whatever table assembly you want, adapted to fit on the lathe. When not in use it can be made to store under the lathe, giving you another dual use of space.

One last hint: don’t put two tools you will want to use one after the other on the same flippy stand or you’ll be flipping it back and forth all day long. :)

I hope the above is clear enough as I’ve been up for over 48 hours right now and for all I know, I’m typing this in my sleep. If you need anything clarified, let me know and I’ll give it a try.

Johnathan, I have to ask… What metal texture did you use for the table? I like that one better than the default one in Sketchup…

I bet Powermatic die hards are having a hissy fit about that right now…

Anyway, I digress. I have considered a rotary table, but am concerned with how much space it would take…
