A big problem!
Everything going along nicely until we got to a interesting stage, in fact a milestone for this bandsaw build. With tyres fitted to each wheel and mounted on the saw, motor assembly aligned and V-belt tensioned it’s time to fit the blade and test run the saw!
Fitted the blade and while turning the upper wheel adjusted the tracking so the blade was running on the crown of each wheel, then wound up the blade tension and again checked the tracking – all OK. Time to turn on power and yes…she works!!!
Blade tracking nicely but too much shaking... why?
No point to go any further until we work out where it’s coming from, forensic investigation required. I suspect the problem is with the lower wheel, I made the upper wheel first and by the time I got to looking for material for the lower wheel there wasn't much Melamine left. With hindsight should have got the van out to go buy some more from Bunnings, it’s on the shopping list – but did not. Instead scrounged around and found a couple of pieces big enough to cut 14” discs, but one bit looked a bit sus…maybe absorbed some moisture – should be OK will it be OK?
Don’t like to back peddle but when you’re pushing the creative boundaries' this sort of thing is inevitable – push on. Removed the lower wheel for closer inspection and at this bare bones point should have turned the motor on to check for vibration/shaking etc. but did not – that came back to bite!
Back soon...
