Does anyone know how to make a staking machine for breaking tanned skins? I was at a commercial tannery about 2 years ago and they had a simple homemade device for the final breaking of skins. I did not pay alot of attention at that time on how it was made, but from what I remember, it used a steel auger rigged with a electric motor turning at a slow r.p.m. The skin was fed into the screw action of the auger, then pulled out. This was repeated until the skin was soft. If anyone is familiar with a machine like this or any other device that would do the same job and could be home built, I would appreciate a response or telephone number, so I could talk to you about this.

these generally are always in contact with the hide, and are cushioned against a rubber aircraft tire, the paddlewheel rotates and the wheel has a peddle to allow you to put more pressure on it. JohnC
Larry - I think I know what you are referring to. I saw a similiar machine at the BASF Labs in Rensaleer NY recently. Its like a Turner Shaving machine blade with a covering over it, and as it passes over the skin it spreads it out and obviously pulls the fibers apart to soften it. Unfortunately I wasnt able to get the name of the type of staker it was.
However - my own thoughts about staking machines is that they are merely a way of making up for using poor oils in your process. Basically , your tumbling Drum (at least a 4' X 6' - and 100# of sawdust per load)should do the softening work, and a staker shouldnt have to be used! You're better off trying to find an oil that works better! Lets face it - if you have to stake - it costs you money (time is money), whereas a good tanning oil will compensate and save you money! Less labor! Which is one of the highest costs in tanning - whether its your labor or someone you hire!
I checked my notes on that machine - it's a Mollissa Staking machine with a 3' 3 1/2" blade, covered with a rubber sheathing.
