Thankfully there is room on the motor pulley to lower the belt and still maintain full contact. I obviously can’t lower the motor pulley, so that would leave….. raising the spindle pulley…
Seeing as this is mounted in a housed bearing, a bit tricky, not impossible, but some thinking would be required.
The other option, and the easiest, would be to shim up the housing a few mill..
Anyway, I didn’t have to do any of that so…. To me, this is like a big red zit on the end of the nose, but it will work, just not how I like it, yes, I’m being anal 😆
