Delrin drive nut (lee)

[progomez]

10x2 trap.....humm no i think the only one i'v got is 1/2" 10x2 in ACME. I can send you some delrin and you could grab a tap from ebay ?

I thought of buying some delrin block from ebay. I have some delrin 10x2 round nuts but they are a pain to mount unlike the block ones you supplied.

How straight forward is it to make a tap using a length of trapezoidal screw ?
