Hmm, seems quite elaborate, just to clamp something. What do you plan on clamping, and how much pressure? I repurposed a caulking gun on a saw sled for a clamp. Worked like a charm, very inexpensive, don't know the pressure but it was capable of quite a more than needed, or desired, and adding another would have no problem. And so very little to go wrong.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
