[DeTomaso] Fw: Re: Pantera fall down go boom :<(

[B Hower]

I will not use the size hole I have in there now, but wanted to test the aim of the oil stream before I try another plug and hole. The hole I have is too large < .060 --------- and I put a piece of ss wire that is .041 in that hole and I still have more than I think is necessary. I am going for .020 and run another test.
 
Thanks for the plug size information,
 
Bud #3400

I had some cautioning (tks Doug) not to go over 0.030 with the hole, so 
I'm just looking for a machinist now.

My alternative is - that'a a 5/8 x 1/2" UNF internal hex plug.
I should be able to buy that in brass which would be drillable.
Anyone know a reason not to use brass in that spot?

tks
