I created a thread not to long about the same thing. I needed to create some dubbing brushes for a fly called the Sleeze Burger. You can buy a device called the cyclone dubbing twister or something like that for $60. There was no way I was going to pay that for something I knew I could build.
This is how I built it:
(You can make the dimensions as you want)
The base is 14.5 inches long x 5.5 inches wide.
The vertical piece of wood is 11.5 inches long with an inch and a half cut out
I then took a metal screw in hook and glued that into a .22mag casing. I drilled a hole through the post and drilled a screw into the butt end of the casing with a small piece of wood for a handle.
One the other end of the piece of wood I put a screw in place to hole the other end of the wire.
That is pretty much it.
I did find it difficult to get the rabbit to flare out so what I did to help hold the hair in place while removing from the hide is place a piece of double sided tape along the railing.
I havent tried to create a dubbing brush with dubbing I imagine its a little easier to work with.
Here is a youtube video of the Sleeze Burger being tied:
Hope that wasnt to confusing.
