Featherboard for Bandsaw Resawing

Motivation

I didn't really have access to a small amount of reasonably priced rubber that would work well for resawing. I think the TPU cost for this build is less than a dollar. And I've tuned its profile so it's stiff at the base, but allows for some flex near the end. I'm quite happy with it.

I also had trouble avoiding warping with such a large base. Since it doesn't really matter if the top face is a little convex, I decided to make it printable up-side-down, and accept that warping will just happen. Worked a treat for me.

I've also shared a link to the OnShape doc. I have parameterized it or anything like that. But I'm open to if someone asks.

Happy printing!

Print Instructions

tldr; Print body up-side-down; 50% infill for squeegee; skip the feet.

Main body

You have two options: a slot for M6 or M8 threaded rod. Highly recommend a material with low creep (ABS, ASA). And then print up-side-down, because it is very difficult to avoid warping. This accessory works best if it has full flat contact with the bandsaw bed.

If it warps and peels off the print bed while up-side-down, the top of the print (which is the bottom) will still come out nice and flat, and it won't affect the functionality.

Rubber Squeegee

Printed with 50% infill, 3 perimeters, any layer height you like. I find a smaller layer height is better for TPU, since it doesn't take any longer. I used gyroid style infill, but I don't think it will make much of a difference.

Feet

Remember to print multiple of these, as indicated by their filenames.

These are optional. Honestly, I didn't even use them in the end, with a properly flat base, I find it's more than steady enough for my needs.

Extra Ingredients

• 1 x T-nut for your slot size
• 1 x M6 or M8 or ¼" threaded rod at least 170mm long
• 1 x knob for the threaded rod
• 3 x M6 bolts > 25mm long
• 3 x M6 nuts
• 6 washers (optional, recommended)
