	1" to the side of most of the liners we put in threaded inserts. We use 5/16" bolts, that is what we use the most of. It is a good size and more than strong enough. To match we used 5/16 ID inserts. Any insert with an internal thread of 5/16 or 3/8 will work well.

	Pilot hole drilled. We recommend letting the liners sit overnight before use, but that doesn't mean you cannot do the tapping.

	Thread the hole. Most higher quality, larger taps have a hole in the shank. The hole allows the use of a dead center to align the tap. Hold downward force against the tap with the manual feed.

	Tapped. The top of the hole looks jagged because of the tape.

	Clean the hole with break cleaner.

	Most thread inserts have some sort of locker on them. At a minimum we put red Locktite on them as well. Other times we wire brush the other red stuff off, then Locktite them.

	Tighten in the insert.

	Insert in.
