great work Nick.
Here's one of a few leather belts I have made - for the wife of a very good friend. Gratis, naturallly.
Made from 5mm thick English pit-tanned leather and 1 1/2" wide. It was dyed top side only with Fiebings Professional Walnut Oil Dye and their black Edge-Kote. Copper saddler's rivets and super strong, synthetic, dark brown tiger thread fully stitched through the leather loop. The entire belt was then subjected to several coats of Fiebings Resolene to seal in the sye and add some water resistance. The buckle is a vintage English-made solid brass Buxton type from the 70's. I also included a solid brass slide just in case the belt end hung inconveniently between belt loops.
I've just ordered a very nice looking piece of 6mm thick Dark Brown veg tanned Buffalo hide from which I hope to make a 1 3/4" wide heavy belt for myself. I've had this huge and very heavy solid brass with steel prong buckle in just the right size and so far I hope to construct it with 70lb breaking strain artificial sinew and solid brass saddler's rivets which I managed to procure from the USA.
Lastly but by no means least, I promised my daughter a nice red belt for her jeans with a shiny silver buckle so have ordered some dyed through leather today and just have to get a 1" nickel roller buckle sorted then I'll be good to go. Of course, I'll make the bairn's one first. Honest.....
Hope you like it,
Graeme
The 1950/52 pattern trousers are the cross-over belt type so I've not copied directly. While it's (cross-over belts) a nice feature, it's not really suitable for dressier trousers.
