Simple Carriage Stop

[Wongster]

I'll take a look when I get back home later. The far side may be a problem, with the motor guard blocking.

Hello Wong,
You only really need the one clamping screw, it doesn't really need to be in the centre either, while it might sound wrong an offset bolt will apply more pressure to one side than the other but this will all balance out and give exactly the same net frictional force, long story short you can have one bolt near the side closest to you and it'll work fine,
If you use any 1mm pitch thread for the stop it is pretty straight forward to make a 10 or 20 point graduated knob which will give accuracy of 0.1mm or 0.05mm respectively, 0.05 is just about 0.002" which really is as good as many of us will ever need on a carriage stop.

M10x1mm and M8x1mm threaded rod should be fairly easy to get in any metric country, if not a suitable set screw will be, so too with the taps, or of course you could turn the thread yourself, after thirty odd years (some of those were very odd years) I use commercial threaded parts where I can, I don't need the practice and rolled threads are often better than turned ones anyway, but if you want to get some threading experience in this is about as good a practice job as is possible.

I hope this is in some way useful, it's all just my $0.02 of course.
Best Regards
Rick
