Thanks Steve!     How the plug factory coming along?

Dave

I have 1/4-32 side fire (Dale Detrich design) $10
8-40 side fire $15
8-40 with conventional ground strap $15

Tomorrow I am going to make Insulators for 10-40's. I started bases but some tooling wont be here until Jan 5th. I would think I will have 10-40 done by the end of Jan. Would be sooner but i have to work every day from the 2nd - 12th.

10-40's will be $15

It does Bill.   gives you a whole new outlook I'll tell ya!


I finished the liners.   Now on to the pistons.    I parted off the chucking pieces, and made up a Westbury holding fixture which is a turned spigot that fits the piston recess and back face tight and held on with a eye bolt and a temporary wrist pin.    But   before I do that, I need to work up a 0.040" ring grooving tool for the piston rings.   Pictures tomorrow.. i got a lot done today, including the rotary table adapter as well.   I'll take pictures of that and update tomorrow

Hello Steamer!

I'm not knocking anything but a .040 wide groove seems excessive for the 1 inch bore. Trimble method says a .043 thick ring .022 wide. I'm just wondering if that's what's in the drawings. A .031 inch wide is a pretty standard grooving insert. If you skinny up the ring to .0295 with a .031 groove it might make things a bit easier. With the .043 thickness it should have plenty of wall pressure. Might save you from having to grind a crazy small tool without sacrificing a good ring seal. I honed the pacifier to .750 and put .027's in it and it didn't even smoke after a few minutes of running.

Just trying to help!
