Sturdy depth stop for large forstner bits. While I did not remix tto's model, I was heavily inspired by his design. I found that the larger depth stops flexed too much for my needs. Additionally, it was too easy to overtighten and strip out the pure plastic screw holes. I added recesses for 3mm nuts. I used 3x10 scews to draw the nuts down into the recesses. Yes, I get the irony of using metric hardware for an imperial bit size. I have a lot of small metric screws on hand left over from other projects.
I have Rockler branded Forstner bits, so the collet is sized to fit the bits I have.
I used OpenSCAD to model the design. If anyone wants the design file, let me know and I will post it. I will need to add a bunch of comments to the scripts so it makes sense to other folks. Design will work for either metric or imperial.
I only needed a big depth stop for now, but I can add additional sizes if needed. I will need three measurements if you request a new model, circumference of the bit, height of the bottom portion with the cutters, and the shaft diameter.
