White lightnin installation

[stuartg]

Okay, I'm working on my second build and installing a white lightnin touchhole liner from Jim Chambers (not the TOW version). So far I've drilled and tap the hole and slightly countersunk for the shoulder using an 82 degree countersink as indicated on the directions from Jim Chambers. My question is...did I countersink it enough or does it need more?

Here are some pics:







As always, thanks!

I would set it just a hair deeper.

I would set it just a hair deeper.

i agree. but then again, my opinion and a boarding pass would get you on the plane.

The deeper the ctsk, the longer the land of the TH. I usually get a TH w/ about a .03-.04 land. If the ctsk is too shallow, then the land could be only a "feathered edge" which could blow out.....so, lean towards a deeper ctsk.Judging from your pics, I would say you could go slightly deeper......Fred

Agree with others. Keep goin. I bury that final flange a bit more. Looks like yours is still proud of barrel surface. Then check inside for protrusion into bore before you cut off sacrificial nub.

I've still got a good bit of barrel before the liner starts to protrude, so I could definitely go some more.

I agree the liner needs to go a little deeper.
I think it's camera angle but how are the breech plug threads. They look galled in the picture.

 

[stuartg]

Threads are fine, just as it came from Rice. That's just the manure from when I drilled the hole and tapped it with cutting oil. It obviously needs a wipe down when I'm done.

Ah good, I didn't really think you would install a liner on a barrel with messed up breech threads. :thumbsup:

I went a tad deeper and it turned out great. Thanks for everyone's input!

Looks very nice! that's what it's supposed to look like!.

After opening up the factory TH w/ a #51 drill {.067}, a ctsk is very lightly used to put a couple three thousands ctsk...just enough to break the sharp corner. Neat job......Fred

Thanks, Fred. I was very please with how easy the whole procedure went.

With it being my first time putting one of these in, I put it a smidge over 1/16 in front of the breech plug face. That way if I messed it up I could go back with a bigger liner with no problems. Do you think it being a little forward of the plug will negatively effect ignition times or anything?

One advantage of the WL being 1/16" ahead of the breechplug face is that the BP fouling is less likely to clog the parabolic cone of the WL TH liner when swabbing....Again...a very neat installation.....Fred

Very nice installation. That's the way it should be done. No problem with it being just 1/16 inch ahead of the breach plug face. In fact, that may be the best location because of it not being bothered with "stuff" building up on the breach face and restricting the flash through the touch hole. Ya done good! :thumbsup:
