This is a quite easy tool that can help you make leather acorns quickly, maybe you can use it to develop more business chances :)
The material is aluminium alloy, very good quality, strong and light, no need to worry about the attrition at all.
There are 4 parts as one kit, two for making the body and two for making the head.
The diameter of the poles are 2.5cm and 3cm. so you can image how large the acorn is.
There are two versions:
One is silver version, the price is 55$, it doesn't have oxide layer, if you use frequently, don't worry about rust at all.
The other one is black version, the price is 65$, it has an oxide layer on, so it won't get rusty if you don't use frequently.
Actually, if the silver version has rust, just clean it with a piece of 5000# sand paper, it will come back shining. But anyhow, don't use sand paper on the black one!
And one more thing: the black one won't lose color when you use, don't worry about it.
How to make it?
Step 1: Wet your vegetable tanned leather absolutly in a pool or basin that with water.
Step 2: Put the wetted leather in the mold and fasten them with a G clamp or a vise 10-20mins.
Step 3: Loosen the G clamp or vise and take out the molded leather.
Step 4: Cut off the redundant leather and paint the color you want, glue them together :)
I attached some pictures of the tutorial, you need it.
