I wanted a burnisher to use on the back side of leather for belts and whatever else I may want to use it for.
Originally I was going to buy one of those nice tempered glass ones but couldn't find one made in a country I support so I decided to make my own.
I made one out of a piece of 3/8" x 3 " x 3-1/4" stainless.
It worked fine but it was heavy. If you dropped it, it could break a toe and when it went off the edge of the leather, it could damage your work surface if it's something like marble, slate, etc.
I made another one out of mahogany (because that was what I had on hand).
It didn't work all that great because the wood dragged on the leather and slicking was difficult. I didn't want to spend $70+ for a piece of lignum vitae, which is the best stuff for the job. Instead, I rubbed it with beeswax, melted that with a heat gun then rubbed it in with a paper towel. I did this repeatedly until the whole thing was a shade darker and waxy to the feel, like lignum vitae is. That did the trick nicely.
To get a really good test of the two, I did one end of a scrap with one and the other end with the other one. Instead of water, I used gum tragacanth. The end done with the mahogany burnisher was shinier than the one done with the stainless. In the photo, that is the left end.
Just to make sure it wasn't due to the direction I was working the leather I dampened the scrap again and did both ends with the mahogany. Both ends were as shiny as the one end was before. Mahogany won hands down.
Maybe I'll fork over the cash for a piece of lignum vitae one of these days but for now, this thing works great!
EDIT: I forgot the last photo so that's in, now.
