Set triggers?

[TNHillbilly]

Is there a 'primer' somewhere showing the different types of set triggers? For example, what's the difference between a 'single set' and 'double set'? Is there some reason to chose one over the other, perhaps for hunting, target, off-hand shooting? Seems, too, that one needs a longer sear arm to properly move the front trigger rearward so as not to have to reach for the trigger.

A single set trigger is 1 trigger. Normally you would push it forward to set it. Normally used on target rifles, bench rest, chunk guns, etc.

A double set trigger is 2 triggers, the rear one sets the front one, or you can use just the front one. Used for hunting rifles & target rifles.

Almost every double set trigger asm. I ever installed I had to add to the triggerbars because they were not tall enough. Sometimes you can bend the sear arm & not have to add, but sometimes not......

If the couple set is installed in the proper position, you do not need a longer sear arm, both triggerbars will hit the sear arm.

You can to to R.E.Davis site & see some triggers.

There are basically four types of set triggers - double set, single action which has two triggers and must be set before firing; double set double action, which may be fired either set or unset; singe set single action, wherein a single trigger must be pushed forward to set it before firing; and single set double action which can be fired either set or unset just like a normal single trigger. The last is very rare, I believe. Single set triggers are rare on American longarms, I think, though there is one on a nice silver mounted straight-rifle by J.P. Beck. Double sets are common - I think the single action type being most common in the 18th century, but my information is limited to Peter Alexander's examples in The Gunsmith of Grenville County.

one of the best primers I can think of would be the track of the wolf cataloge. good descriptions,life size pics, and a tutorial on inletting and adjusting.

Are there drawings/schematics available of these various types? Pictures are nice, but it would be nice to know how to make them. I am making my third set of the type which the rear trigger is pulled to set the front trigger-the front trigger will not trip the sear. That's because it's the only one I can copy from.

Pete Alexander has drawings, but no measurements - you would have to work those out for yourself. He also has what appear to be pretty good instructions for making them, though as I haven't ever tried to make a set I couldn't say for sure. TotW catalog has some examples as well that might help getting the geometry right.

What I have been calling single and double action types Alexander calls simple and universal respectively. That may help avoid confusion...

Sorry, I don't know Pete Alexander. I can work from a sketch but not familiar with your reference.

Pete Alexander is the author of the builders boPete Alexander is the author of the builders book The Gunsmiths of Grenfield County .

Most of the triggers you are gonna see used are the single set trigger tht you just push forward to set, and the double set that the rear trigger sets the front one or you can use the front one alone if wanted.

Yes, there are others. Probably more than just 4, but the most common we see in use are the 2 I just discribed.

Why not just buy a trigger to see how it is made & when ya are done with it sell the trigger ya bought.

Well, let's see, I gotta come up with $200 + to buy 2 barrels for my swivel breech U/C; my camper needs a new tire-$150+; my truck needs a front tire, my wife ran over a stump and my mower needs a new part...........yea; $4/gal gas,$4.55 for diesel. I'll put that trigger on my Xmas list. Like a lotta' ole farts, I have way more time than money! O.k. Wulf I'll go the TOW route.

How about I just mail you one, you look at it, draw it all out of what ya want, them mail it back to me & I will use it in this next rifle I am about to start ? :thumbsup:
