Purchased 2 Jorgensen 41012 quick release vises which I am installing on my first bench build. One as a face vise and other as an end vise. My bench top is laminated SYP 2×4’s cut down to 3” thick This model vise has a 3 1/2” by 10” jaw.
1. What is the max length of chop/jaw liner can I put on a 10” jaw?. There is no suggested length in the instructions.
2. The instructions show that the top of the jaw should be 1/2”-3/4” below the bench top. This is ok for the face vise but I need to lower the end vise down in order to avoid bolting the rear face into the end grain of the laminated bench top 2/4”s. I am going to add a cross piece underneath from front to rear on the end so I can have side grain to bolt to. However it will be several inches below where they say I should put the bolts. How low can I lower the top of the jaw below bench level before it affects the vise? I see pictures of vises way lower than 3/4” but don’t know if it is ok with this one. I will be mortising the bench top so the rear face is will be behind the last board of my bench. I plan on wrapping the bench with some oak or maple. Not sure how thick at this point (haven’t built the top yet).
3. In reference to #2 above, is bolting through the rear face into the end grain a really bad thing to do or just not as acceptable as into side grain?
Thanks in advance for any comments!
