A little push block for a project I am working on .
My Grandson was helping in the shop today and I needed to make this block with threads cut in ,not having a tap for 3/4” x 10TPI I decided to make a tap from a piece of the rod .The tap is ground on the end to a slight taper and notched in three places at irregular intervals . The other end is fitted with two counter locked nuts to drive the tap .
I used my cordless impact and a impact socket to drive the tap which I lubricated with some wax slowly into the hole backing out frequently to clear the shavings . The hole in the block was drilled with a spade bit two and a half inches deep on the drill press which is the tool that the little man just loves to use with Grandpa on his side .
This worked like a charm all the way to the bottom of the hole, nice clean thread .We had a interesting and fun time and he is talking of making the other end for the rod next time he comes to help .
