What's up everyone. I've been lurking for several weeks now and am getting ready to post my ZC block and need some help. I have the posts from endyn and the liquid aluminum is on the way but I am unsure of what taps to buy. I know I need 5/16" taps but when I searched www.use-enco.com for the taps there are parameters that I am unsure of like thread size, style, ground thread limit, etc. Can someone post a link or give me the specs on the exact tap to buy?

Thanks.

 

NM...I got what I need. 5/16" drill bit and two different 3/8" taps. A tapered end tap and a bottoming tap.
