I am considering having some shafts retapped. they are currently tapped for a radial pin and I would like them tapped for 3/8-10 is there any reason you would advise against doing this?
thanks John

As long as they are plugged first. To just retap, How would you turn 7. odd threads into 10 threads per inch?
thanks for the info. I knew they needed to be plugged first I just wanted someoene's opinion as to if there was any negative reason for not doing it. I don't know what the material is that is used to plug the old hole and how it bonds to the wood. thanks again

I agree for People who don't know how to hand tap, grinding is a good option.
What are you trying to say? You don't grind threads but you found a way to make standard taps go in straight? I don't think 'hand tapping' (whatever that is) is ever going to be as accurate as grinding. Accurate enough for most maybe, but it's still tapping.Michael Webb said:

Hi Sheldon, I knew this would definitely catch you. As much as I respect you and you know I do. This is one area we will always differ but to each their own. I have never ground threads, I have always tapped them, Yes Sir, my taps have a lead but I had them made, Those mothers charged me $175.00 each but I got what I wanted. But even before the leads, I had no trouble tapping shafts, Dave Doucette taught me a long time ago how to and those buggers spin straight.
I knew you knew it would catch me. But I couldn't help it. You know that statements like that make me jump. 
Why have you never ground threads? It's not that hard to set up, and fairly cheap for what you get out of it. I don't do it very often, but occasionally it is extremely convenient to be able to.

Deleted, Sheldon, Hope you got it.

I grind the threads on my collars, tenon and buttcaps.
I use a tap on radial threaded shafts ( no choice ). One advantage of taps is the major will almost always be right ( with the right tap of course but the common 3/8 10/11 taps aren't that dead ).
