My first time warping this loom

It's a vintage 'kit loom' that I got on ebay; the biggest draw being the price and 20" weaving width! I've made some adjustments like replacing the previous mechanism with threaded inserts for securing the front/back beams, but I probably still need to reinforce the frame further to maintain appropriate tension (see clamps lol). I may end up just screwing the whole thing down to a piece of plywood, but any other suggestions highly appreciated.

The project is a 2 yard, 14" wide scarf made with thrifted yarn- I thought it was probably wool, turns out to be synthetic (burn tested) but for a wonky practice piece it'll do!

I've so enjoyed browsing this incredible community for tips and inspiration so I wanted to contribute, please keep sharing your beautiful work!
