Hi
I do not have a mill yet. I am doing some half a**ed milling on my chinese drill press.
I bought the extended travel carriage kit from LMS.
Good guys and I bought a lot of other stuff from them as well.
I did not try the tapered gib mod, no mill.
I made longer heavier carriage hold down plates for the carriage.
The shim pack was a pain to cut but now the mod is done I am very happy with it.
I made the studs and locktighted them into the carriage.
Nylon lock nuts complete the mod.
The strips are 5" x 3/4" x 3/8"
3/8 is too thick. I had to carve a divit for the carriage traverse gear so it can mesh the rack.
In retrospect I should have made the strips the same thickness as the original.
I had the same sloppy paint job as the others. Sand paper under the rear way to clean it up. some stone work in the same area to clean a seaming variation in thickness of the way.
Now the carriage moves withe same firm pressure the whole length of the ways.
The serial numbers punched in the top of the ways needed some stoning too.
I installed the apron cover too and now have the lead screw cover kit from LMS installed. It is pretty good except for loosing some travel at the right end.
BTW I looked at others ideas for a carriage stop clamp. THey all have issues,
I put my lead screw in neutral and close the half nuts. The compound feed makes any fine adjustments for facing cuts.
I added extra gib adjust screws in the compound.I think I will add a QCTpost.
This will get the tools closer to the post in the compound.
I like the heavy tool post mod, but no mill yet.
I would like a heavier tail stock assembly. Too much flex, even all locked up.
You can see the ends of the longer carriage hold down strips in the pic.
