BG6350 Large XY Table Anti-backlash Nut

thingiverse

For those with the heavy-duty BG6350 XY table from Lukcase, available at Amazon as https://www.amazon.com/Lukcase-Multifunction-Worktable-Compound-Drilling-x/dp/B071V8PJ1S/ref=lp_14589393011_1_9?srs=14589393011&ie=UTF8&qid=1553318654&sr=8-9&th=1, I've created a solution to its backlash issues. I've included the entire assembled model with anti-backlash modifications in a STP file for those who want to make further changes. The threaded rods use M14x3 LH trapezoidal threads; I have the cross-section of the thread available for you to revolve on your own, as exporting it as a STEP would result in an extremely large file. The solution involves adding a direct feature to the existing barrel nuts. To do this, remove the threaded rod, then add the anti-backlash collar over the barrel nut. Re-insert the threaded rod through the barrel nut and into the anti-backlash feature; there's a slight preload in the threads that can be adjusted during bonding/assembly or by applying heat to relax the 'springs' on the anti-backlash modification.
