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.
Machine M002 is in the works. It is a barrel tumbler for wooden parts. This project will allow us to knock sharp edges off of small wooden products by the hundreds at a time. More to come!
At Sinking Valley Woodworks, we take on odd jobs from time to time. One of these odd jobs was some car parts for an old Bentley restoration. Wood was a much more common material in cars in that era.
This particular piece is what goes at the top of the windshield and connects to the roof. It has curves on all faces, and compound curves on most. The new part was made out of Ash, carved on a CNC router, and finished by hand.
Below is some before and after pictures.
Here is a closeup of a 3D printed chess piece. We designed them in solidworks and printed them using a MakerBox Replicator 2 with PLA plastic. It’s on the chess board dining room table.
Here is the chess “board”
Here are the ceramic tiles going into the chess table before the bar top was applied:
Here is a photo we took of Eli marking a piece of wood for cutting.
