I think he was asking about a Leman, not a Lyman.

Al C:
I haven't built one but the Leman is considered to be one of the easier rifles to build offered by Pecatonica River.
One things for sure. There are a lot more photos of a Leman than there are of a full stock Hawken.
As you probably know if you've read much here on the Gunbuilders Bench, ALL of the "kits" offered by the people who supply these Parts Kits are
much more difficult to build than a Lyman, Traditions or similar kit built by one of the big factories.
Locating, drilling and tapping threaded holes, shaping the stock (they all have too much wood), cutting mortices and installing sideplates, trigger guards, butt plates, etc are required.
If you decide to get any of these parts kits I recommend that you have the supplier install the barrel breech plug and the barrel underlugs.
Also, having him cut the sight dovetails is worth the money.
If you know where you want the sights located, tell Dick Greensides at Pecatonica River where you want them. If you don't know, he will know the best place for them. He's been in the business for years and he does know a lot about these things.
