Topic tags/keywords: bench vise installation apron


My first post here, even if I have been reading this forum quite a lot.

Here is my situation.

I want to install a vise (groz DQ-7) on my workbench freshly built. The top of the workbench is made of 2 layers of 3/4 MDF and a 3/4 plywood. There is a glued maple apron (1.25”x3”) around it.

My question is how do I fix the vise to the bench. The bolts’ hole for fixation (close to the back jaw) would have to go through the apron. and the ones further would be fixed into the MDF+Plywood.

I am afraid that fixing a part of the vise into the apron might not be a good idea. It might weaken the apron (only glued). In this scenario, how would you fix the vice?

I would like some recommendations, advice from the experts here.

Thank you in advance.

I have two of those vises on my bench.

My benchtop is 3 layers of 3/4 plywood topped with a layer of 1/2” MDF and 1/8” hardboard (masointe) and banded with a 1×4 Maple.

I, too, did not like how close to the edge the mounting holes would be.

I removed a 14” section from the banding, routed a mortise into the plywood layers the same thickness as the iron vise back jaw. Then spaced the vise down so the top of the jaws would be below the masonite top layer of my bench with spacers under the benchtop.

Then I drilled and counterbored holes so I could thru bolt the vise under the bench with the bolt heads in the counterbores and hidden under the top masonite layer of the benchtop and the front of the back jaw behind the maple banding which I then reattached with countersunk brass screws.

Finally, I made me a Maple liner for the front jaw that was flush to the top of the bench and added dog holes in the jaw so I could clamp large flat work against dogs in the bench top.

If I didn’t loose you in all that wordyness, you can see that My Groz vise is very solidly attached to the bench top, the banding around the top passes tight through the vise and is actually the back jaw (and replacable).

This works perfectly for me. Been using it for almost 2 years.

Thank you.
A picture is sometimes worth a thousand words. I will try to figure out how you make your installation. In the worst case scenario, I will contact you again.

Here is a sketch of the installation method. It shows what is going on better than my photo.
The 1” jaw liner in the sketch is the band that goes around my work bench.
That band/liner is also flush with the leg face so it works like the Roubo style bench. I can clamp long workpieces to the legs for additional support while they are clamped in the vise.

Sorry, I’m a couple days late. Had a big installation project at work.

I too, need to install a vise on/into my (very soon to be built) workbench.
lepelerin thanks for asking this question and crank49, thanks for the illustration.

The only problem now, I won’t have anyone, but myself, to blame if/when I screw up my install!

Nice Mr crNk49 . How do you fix the jaw liners? with screws or bolts.
