I see on some pics of Tweeds where is a small screw & washer in the centre of the board where it attaches to the chassis. Our chassis has a hole but is it meant for a screw? I see no mention of one.Thx.

If your chassis has a hole that aligns with the board but there’s no mention of a screw in the documentation, it could be an oversight or simply a design choice that varies by model.

That small hole on the chassis is indeed meant for a screw to secure the upper real plate. The screw and washer you’ve seen in photos help keep the plate firmly attached and reduce any movement. Even if it’s not always mentioned in manuals, adding that screw is a good idea for stability and longevity. Just make sure to use the right size to avoid any damage!
