Or ruffing it up with a grinder some to help it stay in place better ? OR ??? any Ideas out there Please ! its getting to be quite a pain in the B-- *&%#@ Link to comment Share on other sites More sharing options...
phabib Posted January 30, 2016 Share Posted January 30, 2016 You might try fitting the wedge with some prussian blue. You'd put on the blue, fit the wedge, take off the high spots where the die came off, re-apply die and repeat until you get a lot of contact area and very little blue left after you insert the key. Some shims would help fill in the gaps and that would work too. I found these instructions for fitting a key. http://www.littlegianthammer.com/resources/FitDieKey.pdf Link to comment Share on other sites More sharing options...
plain ol Bill Posted January 31, 2016 Share Posted January 31, 2016 Yes fit the wedge w/ Prussian blue till all the high spots are even. When you put the wedge back in put it in w/ a thin aluminum piece cut from a pop can, or a thin piece of copper. The easily formed piece will take up any spots missed w/ the Prussian blue and also it acts a little "sticky" also to hold the wedge better.

forgemaster Posted February 11, 2016 Share Posted February 11, 2016 Dont rough it up with a grinder that will only cut down on your amount of bearing surface. As mentioned you need to have the majority of the key providing a bearing surface, yes to blue, or we even use a black permanent marker to colour in the surface of the key if we don't have any "bearing blue". I also vote for the shim of soft material, we use steel strapping strip to take up most of the slack, but we also include a strip of Aluminium, to deform and as said its a little sticky.
