I wasn’t sure how difficult it would be to repair t-nuts with this thing, and to be honest, was a bit nervous that I would mess them up further. Turns out - it’s easy! Just make sure you put it in straight. It’s great to have all the t-nuts operational again! Agree with the other reviewers that it is hard to put together. I thought I was doing something wrong, but after checking these reviews I saw that it’s simply a matter of not being afraid to force it together.
