Brennan;
Lutan-F is a great tanning formula. What kind of oil did your dad use on the hide. Also how long did your dad leave the hide dry before oiling it. All hides should hang until they are about 90% dry. Or you can put them in a washing machine and put them on the spin cycle.
Your oil should also be heated before it's put on the hide. Not anymore than 160 degrees though. Oil the hide and let it sit for 24 hrs. any excess oil should be swabbed off. I don't know what your talking about putting the hide in a dryer though.
What you need to do is tumble the hide in hardwood sawdust, until the hide is soft, and suppel. If you don't have a tumbler, you can use a plastic garbage bag with sawdust in it. The sawdust removes the excess oil on the hair and skin, and helps breaks the hide. Also you need good sawdust without any pitch in it. A good oil to get is Bruce Rittels Pro Plus Oil.
Hope this helps you out some
