I had seriously thought about your problem Mort, and realized I had a drawer full of broken MTH cross head guides as well,….I never paid them too much attention, but as my personal supply of Hudson parts ( and this applies to anything) dwindles, as I’ve stated in previous repair solutions threads, some of these parts will HAVE to be repaired or rebuilt to prevent our locomotives from becoming shelf queens,…..so here’s a repair solution for broken cross head guides …..now keep in mind, I whipped this up in 20-30 minutes, so please excuse the crudeness, it needs a lot more refining to pass my evaluation, but the part is sturdy and strong, ….all I did was take a piece of brass square stock, cut out the broken section for a clean fit of the brass, drill & tap the brass stock for a 2 mm screw, and TA-DA!…a repaired part,….at least if these parts become NLA, something can be done to make a viable acceptable repair,….the refinements I’d make are to use a countersunk 2mm screw, and better made guide arm,…but again, this is something I whipped up real quick just to see if a repair is possible,…….and it is,..😉
