I use a woodcraft press... But mine is slightly modded.
I took the knob off, and threw it in the trash and replaced it with a simple bolt that is about 3" longer. I dedicated a small pair of vice grips as the new "knob" which is much more user friendly.
I also made a wooden "cap" that fits over the metal end of the pressing parts, so now it is wood and delrin instead of metal and delrin.
And lastly, I mounted it to the wall in a vertical position so gravity helps me open the press further when needed. I like it alot and have no intentions of changing it, or switching.
There are plans somewhere to make a homemade one out of all wood that is pretty slick. I used to have one, but my fancy wooden tool making skills arent so hot and it was a POS.
Hope that gives you some more ideas!
