A little while ago I posted about my new cloth winding drum<\/a>. Up until that point a lot of it had been built, but I still didn’t have any of the 1L worm gears needed to drive the turntable ends to the drum. Only the 3D LDraw model showed that it’d work.<\/p>\n\n\n\n

Since then, I’ve given in and ordered some via BrickOwl<\/a>. I finally had the opportunity to test the build out and, unfortunately, it didn’t work as intended. The turntables could easily skip off the worm gears under load – loads which it’s likely to see in operation due to the tension in the warp threads. A little bit of investigation showed that the structures that were holding the worm gears in place were flexing under load. There was nothing to stop the split cross-blocks from rotating a little. Since then I’ve redesigned that section to stop that rotation:<\/p>\n\n\n\n

This appears to work perfectly \ud83d\ude42 . Without risking breaking something, I am unable to cause the worm gears to skip on the turntables.<\/p>\n\n\n\n
