Joe's CNC Model 2006

[joecnc2006]

recieved my LoveJoy couplers today to go from the 1/4" Motor shafts to the 1/2"-10 Leadscrews, These things are tough to put together...

Here is a look at the gantry so far...

[Lionclaw]

Joe, are you bolting the sides onto the torsion boxes? Or using threaded rod? I ran 6 pieces of 1/4-20 threaded rod through the whole thing and I'm pretty sure it's responsible for a lot of the gantry strength. You can buy big 10ft pieces at Home Depot for less than $3 a piece. At my local HD it was near the electrical conduit.

Yes i will be using 4 all the way through it i bolted it for now and as soon as i get ready to put it all together i will get the rods and cut them to the right lenth, the bolt place i get everything from they are 2.50 for 10ft. I agree it will increast the strenth, and i will place them as well on the X axis slide carriage.

Are the skins on that gantry torsion box screwed on, or glued? It looks like they're screwed on, but I believe gluing them makes the box much more rigid.

Everything is glued even the rib sections then drill and tapped, the bolts may help a little but does give it that industrial look... lol

Looks great Joe!

Joe,

I'd like to get some of these 1/2 inch inner diameter bearings. Do you still have the part numbers?

[Lionclaw]

I got mine from someone on ebay named "gem_supply".

Here's a link:
