One of previous builders had drilled the pivot and push tube holes in the elevator horn (Wd-405R weldment) 1/8 to 3/16" off. So I figured I'd just weld them shut and drill new holes in the proper positions.
Easy enough to weld them shut with oxy/acetylene Henrob torch.
But I'm having a heck of a time drilling the new holes. Dulls my bits without making any real progress.
Is it just because I have crappy bits or is that a common problem?
I'm thinking about ordering carbide bits. How many pounds of pressure do I need to apply on 1/16" bit? 3/32" bit? 1/8" bit? 3/16" bit?
