Drilled holes too big

[snoopdog]

Headuphis rectumus moment, trying to make a set of paralell clamps. Holes located perfectly, another discussion, rather not talk about it, lol. Then used the wrong bit. At least I stayed mostly out of the cold.

Nah. You need the larger holes for the brass bushings.

Bling!

Naw, you anticipated the need for larger bars!

Obviously to account for shrinkage during cold weather. Mike

I was in the same boat yesterday trying to make a hex tap holder for a Jacobs chuck in the tailstock.
Everything went well till I stuck it in the hex collet holder with a 5/8 collet in the mill vice.
Laid out the 6 hole pattern to drill the holes used the boring bar to remove a lot of the mat'l down to 0.35, the thickness of the die.
Started drilling the holes and lo a behold I had not tightened the collet nut enough and the part turned a bit in the holder!!
Bummer!
back to the drawing board.
I have just enough stock left for 2 more attempts at this point.
Perhaps we should start a new topic thread entitled "What SNAFU followed you to the shop today"!!

At least all these FUBAR parts contribute to the domestic steel industry.

Fubar parts just become other parts only smaller. It is the life cycle of metal.
