I experienced a lot of threads stripping over time. I should replace at least 8- 10 of them by now. I’ve been avoiding them but it won’t last.
Be careful to always clean the threads out well and starting the screw by hand. I ordered some 3-d printed hold downs that work great, were cheap, and are easily cut should the bit run into them.
Heres the files;
The slots could be a hair larger for the 1/4" screws.
Inspired by @KevBarn14 pumpkin box Japanese finishing techniques, I decided to try a different method by burning via collet and end mill shank
Biscuit cutter out of Maple:
It was a quick thrown together project born out of necessity although it didn’t finish in time and I ended up using a mason jar. I tapered it using my oscillating belt sander.
I don’t have a problem with the visual design, but will the coatings be a sufficient barrier to prevent the wood grain expansion / contraction from cracking the joints or giving you a discontinuity at the edges?
Perfect! is the Tormach 24r in the hobby field? I just had a friend order one for his business and look forward to helping him dial it in while he waits for the ATC upgrade to come out for it. I hope they don’t use the JGL line and go for a custom made spindle or use the FM series from cnc depot with ceramic bearings.
I will be joining proven cut as soon as my HDM gets here and I hope you went all out with it in aluminum.

Been hobby-idle with too many work projects lately. But Sunday I had time to update Vcarve Pro and by way of experimenting with new features and reminding myself of how existing features worked did a few things.

Files from one of the FB groups. Need sealing with shellac, edge sanding and painting. Girlfriend’s daughter already claimed Grogu. Not planning to sell them so not worried about IP issues.
In the meantime, some easy metalwork. I needed to knock up some Aluminium plates to work as decorative / reinforcement plates for some wood strips we’re using as hangars for acoustic treatment panels. A friend is covering the ceiling of his studio in aluminium trusswork and acoustic panels. Yes, the same person I built the desk for.
