Sewing Cabinet (how to adjust)
I recently got a 15-91 and it came with a sewing cabinet, specifically a No. 40 Cabinet (Queen Anne Style). Overall it seems to be in good shape however I noticed the left leaf is not actually level when it is folded out (it angles towards the ground slightly). It's enough of a lean that I would like to try to see if I could adjust it. Has anyone done this type of work before? Would the best approach to try to install some sort of support arm? There doesn't currently seem to be one on the table but I did notice a pin on that side that seemed a bit suspicious and where an arm might have been at one point.
