Here’s an email I recently got:
When you use cowhide to make an Aussie Bullwhip do you use 4oz for your bellies and/or the overlay?
I believe that I once read that you use 2-3oz. ‘kip’ (?) for the bolsters when crafting one in kangaroo leather..?
Basically the answer about what I’m using for bellies in all whips is pretty simple. I use the thinnest veg tanned cow leather I can find. Typically that’s going to be 2-3 ounce leather. However sometimes due to what’s available I have to use a thicker leather and run it through my leather splitter to thin it down.
As for overlays, I would use kangaroo and not kip. You can use kip, but it’s not something I’d do, unless I had some kip I was trying to get rid of. Also I think most Australian whip makers would tell you that for an Aussie Bullwhip, kangaroo for the overlay is a must!
