Need Oddball Taps

Can anyone give me a source to purchase a couple oddball through hole taps ? I need a #3-20 tpi and #3-24 tpi tap to complete restoration of a couple Civil War era firearms. I assume it will have to be a custom job...

Thanks,

Mike

You may just have to fashion them yourself, if no one suggests a source. If you've some spare screws it's fairly easy, esp. if you are just trying to clean up old threads.

MCS , you can order special taps....though not cheap...spend the exrta money and get US made tools..the Chicom taps are junk
mscdirect.com

Sometimes I can find an odd ball tap here;
McMaster-Carr

Check with TRACY TOOLS in the UK. Email Russell and see what he has. They only advertise a small percentage of their stock.
Delivery within the week to North America on a credit card order.
My secret supplier of odd ball kit...and great prices.

I had them make an oddball tap for me, 3/8"-48 tpi, triple lead. Cost was about $200 for two of them. Dunno whether this is competitive or not. Good luck!
