Type of tap

When installing a White Lightening liner, what type of tap do you use?

I would recommend a spiral point tap made out of High Speed Steel, HSS.

It will be easier to start the threading with a taper tap. It will most likely have to be followed up with a plug tap unless you are tapping a large bore barrel and the "taper" of the taper tap can completely enter the bore fully finishing the threads.

A plug tap has a shorter taper (3-5 threads) and can finish the threads started with the taper tap if it bottoms out before finishing.

I agree with Mark. Use a plug tap instead of a taper tap if barrel is small caliber. A taper tap can hit the other side of the barrel before the threads are fully cut. If the barrel side thickness is more than the length of the liner, then use a bottom tap.

What is the thread size you have to use? 6mm?

This is the type of tap I would recommend:

White lightning liners have a non standard tap. You need to buy the tap from the liner supplier.

1/4 - 32 size tap, Amazon sells them.

All sizes of White Lightnings have 32 TPI. I've found that the 1/4-32 WL is good for all the bbl sizes and that's what I have used. Bought {2} 1/4-32 taps from Chambers ...one has the point and some of the lead in threads ground off and the other is used as is to start the tapping. The modified tap prevents the tap from contacting the opposite side of the bore when achieving a fully threaded hole......Fred

When installing a White Lightening liner, what type of tap do you use?

I use the tap that Jim Chambers sells for his White Lightening installations. He surely knows what works - why reinvent the wheel?

 

[The Appalachian]

Since it's considered a non standard liner, wouldn't the White Lightning itself be a reinvention of the wheel?

Ah yep.......

TH liners come in all sorts of sizes seeing many are one of a kind...being hand crafted. So what's "non standard"? Previous to the WL, I made my own but the elliptical cone switched me over....Fred
