Good morning everyone,
Does anyone know what the correct clearance is between the wagon and the bed rails?
I have to mount “Laminated Shim-Rear Strip” (Ka6 and Ka10) and I would like to know how much space to leave to allow the correct sliding of the carriage.
Thank you in advance for your comments.

In case anyone is missing the relevant info, this would appear to relate to a Wide Guide Myford Super 7, and the shim packs on the carriage.
I’ve never had to adjust mine, but if/when I do, I’ll move the carriage to the least worn part of the bed, likely near the tailstock.
Set up a clock gauge on the bed and see how much vertical play there is when lifting front and back of the carriage.
I’d then remove that amount of shims. If the play is intermediate between shims, take an extra one out and replace with one or more layers of thin paper to get the correct sliding fit.

So is 0.05 of vertical movement okay or is it too much?

The correct Myford clearance was 0.002″ or 0.05 mm when I had a similar machine. The shims are this thickness and in practice this clearance is a maximum, as in my experience it is generally less.
