Working on another machine to speed up yet another tedious workshop process. Think of it as a special router table that takes 2 routers set to 45 degree angles. The guide (not shown) will allow precise alignment of the work piece AND cover the cutters to prevent injury.
The Barrel Sander is coming along again, after a small detour to build the (M003) Auto Loading jig. Here is the nine sides bolted inside the barrel. They do three things:
- Make the barrel stronger so the wheels that it turns on have more support than just thin metal.
- Provide a disrupted circle which will cause the materials to actually turn instead of sliding.
- Protect the inside of the barrel from the sanding action.
After years of making the same part repeatedly on the CNC router, I finally decided it was time to make the router load it’s own material.
Friction is a valid way to hold a part for routing. That is how most vices and clamps work. The key here is to calculate an amount of friction that will resist the cutting forces while at the same time keeping it low enough for the router to be able to overcome it while loading and unloading.
I’ll post more on this when we have it working. For now, here is a cool picture of the jig.
Here is a box that Zechariah designed in Fusion 360 in about 20 minutes, complete with a hinged lid.
Modern CAD software is amazing.
