Rounded the inner dimension up to 89mm, and replaced the 6mm spacers and 1mm shims with 9mm spacers. There's about 0.1mm of wiggle room, you can...
Yeah, pretty much the same concept as the CNCRP rack and pinion system, except I'm going to use gears instead of a belt and pulleys.
I think I may have a winner here - 6063 angle 2" x 3" x 1/4", butted together on top with a plate bolted on top of that. The inside dimensions...
Pivot point, plus a spring tension point down towards the pinion. I haven't modeled that part yet. For the pivot, I started with an 8mm diameter...
Something along these lines, then? 1/4" x 1.5" x 1.5" 6063 aluminum angle, square edged. I could even go with 2" angle, though I'd have to make...
Moving on to the gantry X axis... I decided to use two C-beams back to back - an I-Beam, if you will. They will be bolted together. Adapted the...
Added the drive bolt, M8 socket head cap screw, 60mm long. Also added the pivot bar, a 20mm OD x 8mm ID x 28mm high cylinder. The assembly is...
Reworked the drive assembly by quite a bit.. Gear Rack is now mounted below the gantry plates, eliminating having to bulk out the plate to go...
An idea I am toying with for a C-beam router using 1500mm lengths, with a build area of 48"x48" or so. Movement may be done with helical rack and...
Revised the wheel layout a bit, spaced them out in 20mm increments. Decided I may try to make my own eccentric cams out of 10mm hex bar stock,...
Better view of the pinion and rack mesh, from the inside.. The clearance between the upper part of the bearing block and the rack teeth is a...
Thanks for the link - I was thinking of encasing the gears in between two aluminum plates. The gearbox assembly would be mounted vertically to...
Here's the racks, if anyone's interested: CNC Precision Rack and Pinion M1.0 - 1500mm (59") - 3pcs Racks and Pinions Set The pinions are 1/4"...
Here's what I've come up with so far, inverting the rack (teeth down) and cutting out a hollow for the pinion. I've also replaced the low-profile...
The wheels on the top are the ones with the eccentrics, and the ones on the bottom are the fixed load bearing wheels. Do you think two eccentrics...
Inside view of the gantry plates with the wheels that go inside the C-beam. I managed to find a Modulus 1.0 gear rack set in 1500mm lengths with...
Bearing block - based on a 5/8" thick piece of 6061 aluminum bar stock. The gear rack is 20mm tall, 15mm wide - so the surface of the bearing...
Quick shot of using the larger solid V-wheels, inside of the C-beam structure. Mounted to the top portion of the rail is 20x20mm Mod 2 rack - the...
Giuliano M published a new build: C-Beam Router using 1500mm lengths, 48x48" build area, and rack and pinion movement. Read more about this...
Sorry, started a new job about a month ago and haven't had time recently. I will probably catch up with it in a few weeks, and maybe order some...
