Giant 20' x 3' x 2' router build

belts arrived, i had to go with 5 teeth less on the motors to get it to fit unfortunately well unless the belts stretch a fraction as it is right between sizes.

I mentioned it in a post earlier that i am geting a small amount of flex from the main back uprights which for the surfboards really isn't a problem as the load on the machine will be close to nothing cutting foam however i would like to try and reduce it as much as posable. I have been wondering about two options the first being bolting a pice of 90deg angle steel to each leg ( i cant get large enough channel or T section) and the second idea was to fill each of the current aluminium legs with a resin/granite mix or maybe even a concrete mix which i have been reading about which may help in other ways as well.

Can any one give any suggestions as to what may be best?

many thanks

Just a thought could you not bracket them to the wall? ..Clive

I was planing on bolting it to the floor i would prefer not to rely on the wall as it may well end up being moved else were were that may not be a option.

many thanks

Bolting to the wall with brackets would be a quick simple fix. But if you have to move it so that it is free standing you might be able to triangulate the back of the uprights bit like an apex roof truss on end. ..Clive

Looking at other designs on youtube I found this one. Different layout approach which would be stiffer than your cantilever. Bit late I know, but any ideas from here?

In terms of improving what you have - I don't think you'll get very far filling the back supports, or adding angle iron. You are looking for a big step change to make a difference. As Clive suggested either bolting to the wall or adding diagonals on each end coming forward to the front of the machine and onto the floor would be much better.

Can you post a picture of the whole thing now it is generally together? You might get a few more ideas . .
