Ok, I know I'm supposed to be on vacation/holiday.......

But.... I tried to make a punch for some gaskets I need for my steam engine.....for the cylinder end caps.
I took a piece of brass bar and bored it to 1/2 in.... turned a piece of steel to match the hole diameter.....In the gasket paper, I can punch a hole, all is good...
Now, I need to make the outside dia 1"....so I made another block of steel (bar) turned to the right diameter with a hole in the centre to take the punch (1/2").. and used that to centre the gasket paper...with me so far?
Now, I machined another piece with an internal diameter to match, now the probs start....
When I try to cut the o/d, the punch doesnt cut a full circle....
Something is wrong! cant figure out what....the same thing happens with the 4 pcd holes ....
(I made the two blocks with holes machined to the pcd required and machined a punch to suit....)
So, how do you make your cylinder gaskets?
