Re: New wasteboard using v-slot extrusions

I just finished upgrading my wasteboard to t-slot extrusions last night. Previously I had a single piece MDF wasteboard with a zillion 1/4-20 thread inserts everywhere (except where I needed them on any particular job :lol: ) IMG_6855.jpg I wanted the option to use lubricant/coolant when cutting met...

I have a question about Linear Rails

I'm upgrading my z-axis -- a poor man's version of the HDZ. I'll share the details in a couple of weeks (assuming it works. :lol: )... I have a question for the community. I bought really, really cheap MGN12 linear rails from Banggood: https://www.banggood.com/Machifit-MGN12-100-1000mm-Linear-Rail-G...

Re: Home-Made Rotary Table

No video yet. I'll see what I can do. I use Onshape for CAD, MeshCAM for CAD, and Carbide Motion for gcode. I did a quick and dirty trial and it appears that moving the x-axis 1 meter corresponds to a full revolution of my table. Of course, that will vary depending on your pulley/gear ratio. Maybe I...

Re: Home-Made Rotary Table

Assembly Cont. Here's a shot of the final rotary table as well as a spare photo or two. I disconnected the X-axis stepper motor on the grbl board (or whatever it is). It's the plug farthest to the right as you are looking at the front of the Shapeoko. I slide the router over the center line of the s...

Re: Home-Made Rotary Table

Assembly cont. The workpiece needs to be attached to the outer race of the lazy susan somehow. I decided to have a permanent piece and a waste board attached to it. The permanent piece needs to have holes cut in it that matches the locations of the screws for the inner race. The assembly order is: F...

Re: Home-Made Rotary Table

Assembly cont. With the lazy susan in position, I drilled holes corresponding to the inner race into the sliding board. (By the way, the holes as purchased don't go all the way through the races. You'll need to drill them through. No damage is done to the lazy susan that I noticed when I drilled the...

Re: Home-Made Rotary Table

Assembly Cont Time for the lazy susan. I found a better than average quality lazy susan that I though would fit my needs. It's got some slop. It's probably OK for woodworking. Maybe not so good for metal working or high tolerances. Problem is, there's no easy way to add teeth. Eventually, I selected...

Re: Home-Made Rotary Table

Assembly Cont.

I used business cards to shim the sliding table and the guides. I wanted a little slop.

Finally I attached strap iron (with permanent shims -- cut up business cards) to capture the sliding table.
