Have you seen this vise model before?

[machining 4 all]

Thanks for the interest mklotz! Responding to your comments:

- It is not necessary to tighten the fixing screws so much to obtain a good fixation of the claws. The dovetail allows a very effective fixation of the claws on the guide. When I perform machining of precision, usually my machining depth is less in finishing operations, so the claws are not as requested.

- I also tried to make a different vise model. Nothing against it, but have you noticed that most people who post videos making vises use a vise in their manufacture? As I don't have a vise (I now have this one) I used the resources I have (a mini lathe, a milling machine and a drill).

- The system has been designed in this way to allow the claws to move freely. From mechanics, we know that Torque = Force x Distance. Applying a moderate force of 8 kg to the key (in this case Allen M12) which is 110 mm long, a torque of approximately 9.0 N.m (approximately 6.7 Lb.ft). This value is more than enough to hold the components in place.

- Each claw is 30 mm wide, which gives approximately a contact area equal to 2.52e-6 m2 between claws and guide. From mechanics we know that Pressure = Force / Area. If we apply a force moderate equal to 8.0 kg per screw, we will have a pressure of approximately 63.5 MPa (approximately 9200 Psi) acting on each contact between grapple and guide. This pressure, for a hobysta vise, is more than enough to perform small tasks...

- For example, the metal plate that appears in photo 1 and photo 2 was manufactured in this vise. The machining was smooth, without any problem.

- I will definitely machine channels in the jaws to fix fine materials, so I don't have to use parallel shims. However, I will machine and temper two shims where I intend to make these channels.

- I will still perform the machining of the vise base, where I will place two discs so that I can perform rotation, allowing angular machining.

- I forgot to mention, I bought the material for manufacture in the scrap. The total value of the project (material and screws) was an incredible 6 dollars (except my labor, which is part of the fun). The total manufacturing time was approximately 7 hours.

I don't know if I answered everything that you kindly commented, but that's what I thought when executing this project. Thanks again for the considerations!
