All,
I have started a build on a JGRO design in my basement. I am using more or less the JGRO plans with minor modifications. I have attached three pictures.
One of the progress so far. I have cut my linear bearings using a metal blade in the sawsall with the vice holding the angle. I then filed the burrs. I cut a few of the MDF pieces also.
I also attached a picture of the casters and the cut pipe. This is an innovation as suggested to me by a pal of mine. The plan is to use these as my pipe aligners for the y axis at least. So the caster goes on the y supports and the threaded 1.75'' pipe threads into the caster. The hardware store that is orange cut and threaded them for me! The pipe is tapped to fit the bolts, and the 1'' y axis fits inside the pipes. We'll see how it works. It is heavier, but I bet a lot sturdier than MDF or plastic.
I added a picture of the modest tools I am using.
1. Cheap Router and table. Not sure if I want to use the router for my spindle
2. Aluminum straight edge - very useful for guiding the cheap circular saw
3. Drill press I got from Big Lots for $50
4. Sawsall
5. Vice
6. Shop-Vac, maybe I can use this as a dust collector later
7. My old high torque hammer drill - I have gotten a ton of use out of this thing
I have ordered my bearings from a seller on ebay:
608-2RS Inline Skate, skateboard bearings, ABEC 7. They came to $21. Seemed fair.
I plan on using 1/2 10 single start lead screws from ENCO unless someone has a better suggestion. These seem like a good price and I have read on this community that they work well enough.

I am planning on using couplers and anti-backlash nuts from dumpsterCNC. Unless anyone has strong feelings otherwise.

And I plan on a 305 oz-in kit from hobbycnc.
I haven't figured out where to get the other items required such as flange bearings. Maybe mcmastercarr?
As usual any help or advice would be appreciated. Good Luck!
