Is there a trick for enlarging the diameter of a hole? How do you center the bit for the larger diameter hole?
You could make them fit together, only problem is getting them back apart. :smile:I just cut a plug the same size as the original hole from scrap wood. Closely sized hole saws will not fit inside one another.

I like that idea, checked it out and the arbour does not have enough thread on the ones I have.OK, I did some more investigating. Two hole saws on a single arbor.
The inner one is the same diameter as the original, smaller, hole. The outer saw is the diameter which you want to enlarge the hole to. Whaddya think?
Unless you just want to buy this fancy little tool for enlarging holes, slatron's idea works great.:thumbsup:Drill the larger hole in another piece of wood, center that hole over the smaller hole using it as a guide. You'll probably need to clamp it.
Hi Blockhead!Hey Joe - I know this is off topic but I took a look at your website and found your story, how you got back into woodworking. Very inspiring, and I'm glad all worked out okay. Mostly though, I want to comment about the '20s style rocking chair.
My grandmother used to have one very similar, which I've long since forgotten about. I think a friend of my grandfather made it completely with hand tools. Anyway, Thanks for reminding me about it. I think I might attempt to make something similar sometime when all my tools are in the shop (most of my work is on-site), and I'll be sure to match the direction of the seat grain with the sides so I don't have to nail it back together every now and then. :smile:
Look at the post by Makem... with the pictures...I'm not sure what kind of bit you are using or if you are using a hole saw. Either way, if you chuck the original bit (smaller one) back in the drill and can get a center point from it on a piece of scrap that has been clamped, either from the twist bit, forstner or hole saw with the bit extended, this will give you a center mark to drill the larger size hole.
What am I missing here?
Thanks Joe, i have to admit that i didn't do the illustration's they wereThat is a cool solution... I have seen it work... It IS cool! And simple!
Good illustrations!
