I have a couple of older planes lying (pretty early Stanley #5, Millers Falls #9) around that have been giving me trouble when attempting to adjust the blade depth, and google searching hasn't yielded much in the way of useful information. Basically the problem is that the y-adjuster/yoke/watchamacallit that advances with the depth adjuster doesn't advance past a certain point unless I physically push it against the adjuster wheel. I had this problem previously that I think was being caused by a too-thick replacement blade in another plane, but in these cases I am using the stock blade, so it shouldn't be an issue. Strangely, one of the planes with which I am having this problem was working fine until recently, so I am not sure what has changed!
Has anyone encountered this, and if so, what was the fix? Alternatively, I may just have no idea what I am doing .
