Sarge, Have you ever tried using Tandy's Neat-Laq and then tried the hot wax method on the inside?
Just wondering what the outcome may be, could ruin the piece though....
Andy I have used boiling water to soak a piece of leather I made a cigarette case into.
I cut out a wood block the size of a pack of cigarettes and cut the hole large enough to allow for two thicknesses of leather on two opposing sides and one end.
I forced the hot leather into the hole with the wood block and then clamped it for a couple of days. I left it on the roof of a small shed so the SoCal sun would help dry the leather.
When I removed the leather box I had to trim it with tin snips because the leather was so hard. It was about 7-8 ounce leather, heavier than needed but was in the specs I was given as it was made for rough treatment.
A nice side effect was that the inside stretched corners were burnished a very dark brown that was totally unexpected but a very nice surprise.:thumbup:
I lost money on the project but gained a very worthwhile experience so although I spent time that I could've well used in making a more productive commissioned piece I figured that I came out ahead in the end.
And now I know I have because information hard earned and freely given enriches both the receipient and the bestower.
I was never completely satisfied with the Neat-Laq though as any bending on the piece would result in softening the leather moreso than I liked and if you use too much it has a tendency to crack.
Years and years ago, mid '70s Tandy came out with what they called Nature tanned. It was an orangy sort of color that when stamped with simple flower and geometric stamps and then dyed darker over the top turned out nicely different.
The materials used for finishing the NatureTanned stull left it a lot softer than the Neat-Laq though and so wasn't real applicable to sheath making as far as I was concerned.
Probably the best way to get stiffer finished projects besides boiling the leather is to simply use heavier leather. I have a small knife sheath made out of 10-11 ounce leather that is very stiff for its size and has remained so since the '70s.:thumbup:
