I'm making up the thrust frame for the TS3. It's nearing completion but, Would it be better for me to have belt guides on: Slack side only? Centre distance between the two pulleys? A belt guide on both slack and tight side central distance? Or am I better having the guides just before and just after top & bottom pulleys (4 belt guides)?
I'm calling them belt guides, but maybe called something else. Its to stop the V belts twisting.
