yup all the add on bearings are mounted with eccentric bushings so that I can adjust teh fit. on the Y the bearing stud goes through a bushing with an off center hole, for the two X followers, the bearing is mounted to the al spacer piece, which has a stud offset into its base to allow adjust there.
I have cut a couple signs and circles so far testing and tuning the machine, the follower bearings have compensated for the deflection quite well, there is maybe .050" play in the torsional twist of the x under full load (was about .25") and no noticable sag on the y when tramming the table with a dial indicator
the x play should not be noticable for making signs and stuff, and will not even come into play if i get around to usingit as a plasma table too..
end of the day i knew i was pushing it with a light weight (cough cheap) design but will work out for intended usage. granted i probably cant take a 1/4 cut at 40ipm but my little laminate trimmer cant do that either so its an even balance i guess.  |
