Drill bits

[Murville Alleman]

I really need a 3/8" x 18" square taper shank drill bit for the old fashioned hand brace. Drilling into large trunks to install swings, feeders, lights, etc.

Drills & Cutters out of Long Beach, NY should be able to hook you up.

Maybe cut the shaft on a regular bit and weld an extension tube in between the ends?

You could mill or grind a standard shank square too.

Look for people who do timber framing.

There is another forestry sight, FF, that has a timber framing forum. The moderator sells refurbished vintage tools. I've purchased from him and they are 100% top notch.
