Thanks Dave/Bennie Her's a pic of the covers the right way round, I think it looks happier the other way :D With both covers fitted i put a length of 8mm silver steel through the slot and measured the height side to side and front to back, and it was within 0.06mm:- not alf chuffed with that :D :D :D :D :D :ddb: :ddb: :ddb: :ddb: :ddb: Back on the mill and drilled and milled the air ways, and drilled m2 tapping for the valve chest. Then tapped the holes M2 using the tapping stand to get them square, these holes are on both side of the cylinder, on the model they don't do anything, but on the origonal the cylinder sides were spring loaded to take up wear hance covers both side. On with the valve chest now, first square it up to size, then centre spot where the bore is to go for the spool valve. Then in the four jaw chuck clock up a wobble bar centred on the spot centre. Centre drill then drill and ream 8mm. Swap it round clock the centre spot up on the face. Drill through into the 8mm bore and face the boss for the air coupling. Over onto the mill using centre the work and with the DRO drill the holes on the PCD for the coupling. Flip it on the back find the centre and drill the feed ports and 2mm for the studds That was a good morning work :D :D :D :D Any one know where I can buy some M2 studding in the UK. Stew |
