Shaft coring question

I need to core and re-tap a 3/8-11 shaft, but I do not have any
phenolic rod of a big enough diameter. Do you guys ever use purpleheart
or other woods for this application. Or do I need to order the phenolic?

Thanks,
Josh
 
I usually just use maple, but have used phenolic and purpleheart. It will change the hit, IMO, when you use different materials. If you have the ability to turn down phenolic, I can send you a small piece, just PM me the info. I have a few dia. availible. If you can't turn it, just let me know the dia. and I'll cut it down for you, no charge.

I've gotten to the point that I don't like tapping maple for joint threads any time. It doesn't hold up as good as many other materials. I put in a purple heart plug into nearly all shafts that I make. I then drill and tap the purple heart for either an insert or for threads. It's both cheap and holds threads well.

Thank you all for your advice, and rep to you Dave for your generous offer.
I think I will try the purpleheart.
Thanks again,

Bocote, olivewood , madagascar rosewood , padauk and granadillos work b/c they are easy to thread.

I've tried some brown phenolic ferrule material a couple of times but it was just to hard to tap. I figured there was to many other sources than the phenolic which, I feared, was just dulling my expensive taps. I also tried some ABS but it was to soft and I feared it would cross thread in no time. Since I have tons of purple heart I just started using that
