Nice to see that you have started on the Monitor. I have saved the files but have not printed them yet.When I come to that part most probably it will be a soft soldered job like I did on the Corliss.Vince
Bill - my luck held out. Jason - thanks. Well I think that confirms your thinking Dave.1) The chamfer. I didn't see a dimension on the drawing. The drawing looked like 45 degree (90) but without knowing about the olive/nipple I didn't know why. I'd used what I believe to be an 82 degree (41 degree slope) but can remake the part (I have to make another anyway. The plan calls for two.)....Actually, I think I can simply run the center drill in to correct.You can use what taper you have or just recut with the centre drill3) What is the thread pitch on the inlet/outlet of those valves?They are 1/4" x 40 both ends4) Just making sure - CSK is countersink right?Yep5) 'zeenipple' I'm saying nothing For external threading - what should the rod be turned down to before using the die? I thought there was a formula but can't find it.Turning to 5/16 for a 5/16 die did not go well. I had to shave a few thou off.Now it could be that my measurement was off or that the die needs adjusting.Which brings up another...how does one go about adjusting a die?5/16" thread should go straight onto 5/16" bar, did you open te die up a little
And another thing, don't forget to slip the nuts onto the pipe before you solder on the nipples
