The Carleton underhammer is know for it's sliding hammer.

Well, I have 6 fast twist Big Bore blanks [1-58, 4-62s, 1-69] that need to be finished. Had them too long, time to do something with them.

I have a flock of underhammers .32-7ga. Thought I would try something even more different.

The Carleton is a slam fire, triger holds the bolt back. Pull the trigger Slam, Blam!

The brass receiver is milled for the hammer.

Quick change barrel system is done.

Hammer is coil spring fired, not the trigger guard.[nearly done.]

The slide in trigger guard and trigger need to be made.

I have several ideas for a half cock, but haven't decided yet.[simple is best]

Oh, wood.....I have some rough sawed.

Will update progress, not ready for pictures.
