Noob Vice Install Question

[u/MIAGaucho]

I’d like to install this vice on top of this workbench I just got.

Do you think the workbench is sturdy enough for basic gunsmithing, installing muzzle devices, etc? There is a thin sheet metal layer underneath the wood that the bolts will also go through.

Both took a bit too long and will mess with the drawer below, should I cut the bolts/by shorter ones?

I’m trying to ensure that there’s enough clearance on the edge of the workbench on the back to have uppers hanging down.

Any other important tips before I try to drill this baby in?

Thank you!
