Mtm Table “quiver”

I got ahold of one of these awhile back. Got it on a huge discount. The issue I have is that with bags or using a bipod the plastic flexes enough so it looks like you’re seeing mirage! I like the portability; and I know it’s not going to be a concrete or big bench solid. Has anyone experimented with putting low expansion spray foam in them? I have seen that solidify some sketchy door frames when a customer was strapped for $$$ or wanted to “bandaid a compound fracture”. I’d also wondered about pouring epoxy in it. I could cut a plywood top for it as well I suppose. I probably will be a mad scientist. Lol. I’m pretty good at messing with stuff.

Which specific parts are allowing the flex? Is it the table top itself, or is it the leg attachment points where legs meet the table? Is the the footprint of the table?

It'll depend on the final rigidity of the expanding foam. You also MIGHT run the risk of splitting the table top if you use an expanding foam with significant expansion force (and you MIGHT concern yourself with melting the top via the exothermic expansion, but I'd kinda bet against it actually getting hot enough to melt).

I’d also wondered about pouring epoxy in it.

I think by the time you fill that thing with epoxy, you'll have it so heavy that the legs and their attachments won't be happy.

I'd be much more apt to explore inletting stantions through the top and embedding aluminum angle stock into the bottom - BUT only assuming the body itself is flexing. You also MAY end up shifting the failure point - if you stiffen the top too much, the same flexibility at the leg attachment points might simply increase the wear and eventual failure at the attachments.

All questions I’ve asked myself.and I’d come to the same conclusion with the epoxy.
The flex is the table top itself. I realize it’s not going to be a concrete or heavy wood bench solid. I did also notice it’s much less wobbly at 30 and -2 degrees than 70,105 and 85 degrees. It’s plastic and it flexes.

Could you cut a piece of plywood , to match the top, and screw it to the plastic ?

I would like to think "1/2" plywood could be plenty , and even attach a carry strap ?

I have been thinking about something like this also. I could make a table top like this. Make with with plywood and weld 1 1/2" EMT conduit to plates to attach to the table and use 1 1/4" EMT to slide into that and be the legs. I have been using fold up tables and lead sled or not, you just move a little and the scope moves as the table flexes.

A little heavy, but solid with no quivering

You can take the legs off and bolt them to wood.



Or if you want a really solid one, use the wood to make a concrete form for the top and put some real legs under it.

Use the foam designated for windows if you go that route.It is made to expand just enough to fill the cavity.I believe its the blue cap stuff at Home depot and Lowes.
