Ultimate Bandsaw Resaw Guide

I don't like the stressful experience of having to hold a valuable piece of wood against the bandsaw fence, hoping to resaw it perfectly. Particularly as the wood gets wider, it becomes very challenging to get a perfect cut, wasting wood as I have to plane away my mistakes. Existing resaw guides can't be aligned to the saw, or can't be adjusted to the height of any bandsaw. I attempted to fix these issues with this guide.

This guide can be built in any height you'd like. The bottom is 22.5mm, the top 20mm, and each middle section is 22.5mm. So, if you print 5 middle sections, it will be about 140mm high. It's worth making it at least half the max height your bandsaw can cut.

Beyond your 3d printer, it requires a few things:

• One 608 bearing per middle section + one more for the bottom section. These can be purchased at your local hardware store. They should be 22mm in diameter, with an 8mm diameter hole, and 7mm thick.
• An 8mm threaded rod. You'll need 3x the height you decide to make the guide. I just bought a single 1m piece and cut it. It's wise to put a nut on the rod before you cut it, if you unthread the nut after cutting the rod it will clean up the threads at the cut end.
• Some 8mm washers and nuts
• 3 8mm threaded or heat-set inserts. I personally use the threaded inserts which are twisted in with an allen wrench and are commonly used in woodworking.
• If you don't want to clamp it to your bandsaw bench, you'll need a bolt that fits in your T-track, and a knob to attach on the other end of the bolt. This can be 3d printed.

The printing is straightforward, and requires no supports. I printed with ABS, but PLA or PETG would work fine. Print everything upright, as it appears in the screenshot, just remember to clone the middle section.

Once it's printed, insert the threaded inserts into the three holes in the bottom, and screw in your three sections of threaded rod. Then start adding bearings to the middle threaded rod, followed by a middle section, and repeat until you have used up all your middle sections. Finally add the top, some washers, and nuts on the threaded rods.

Once you have it on your bandsaw, adjust the tension in the front and back rods to perfectly align it with the blade. If any part of the guide is coming in contact with the wood before the bearings do (likely the very top or bottom edges), lightly sand the high spot.
