GA.smoky looks like he's got the testing buggy rolling down the track!
Are you going to make vent liners or just nitrate them ?I've got the tooling on the way to make some from grade 8 screws.
There pretty tough as is 36rc
I just happen to have cnc capabilities.What I see in the picture is probably more of a spot drill operation before using a very fine drill...
That isn't designing in a counter sink... ie a counter sink is used to put a flat head/oval head screw in deeper, or even flush a surface. In a vent liner's case it is to increase the surface area for the head to clamp with... the breech plug is countersunk for the head of the vent liner.
As for the particulars of these experiments, I don't care to comment more: For the time and money invested, I don't understand why one wouldn't just buy some 17-4 stainless, heat treated, and carbonited vent liners from my website. Nitride is nice, but unless you have a swiss screw machine mass producing making things like vent liners (with such fine holes) by hand, on a lathe is tedious and time consuming.
The only answer I see is folks like to play. And I'm not opposed to it, I just don't have the time to play on something that I already have on the shelf, inexpensive, & verty effective.
Hey Tom good to meet you.(for the uninitiated... I'm the Tom, Mr Tom is referring to).
And yes GA Smokey, if you are tooled to mass produce/automate, you may have a great opportunity to easily make a useful item. 7
If you are starting with Grade 8, then tooling off the outer layers, you may be better served by re-heat treating, then nitriding... this is more akin to the older version Lehigh used to produce, before they switched to 17-4 (which is why what I sell is 17-4... Lehigh made them).
