I'm definately getting better at this machining lark. I decided to do the Valve Blocks in a 4 jaw. It's paid dividends BIG time. I centered the bar in the 4 jaw. Faced off an end and drilled it 1/8 for 35 mm the 5.5 for 36 mm I have some slow spiral negative rake drills and they really do cut brass like butter. Both holes were slightly out so I machined the 1st side to suite the Hole. Turned it over and machined it to size - 18mm The hole is now centeral. Did the 2nd using the same method. Then hogged them both down equally to 16.5 mm. Measured the hole and pulled the hole central again. Both blocks are within .05 mm, square, and the hole is within .02mm I'll start drilling tomorrow...... Alex. |
