as dyslexik as I'm daft

Turned 4 spacers and cut two bits of steel tonight before getting sick and going home. Bandsaw has been playing up recently and I spent the first few hours fiddling with it trying to get it to cut straight... I put my spare blade on as last resort, and hey presto, straight cuts again. Really vexing, I've spent hours and hours trying different things over the last week. It was a Starrett blade that was nearly new and still sharp, totally scrap.

One way I've over come the out of line cut on my cheapie Machine Mart 4" machine is to tension the blade well and take off a lot of the down ward pressure so the blade runs at 90 degrees to what's being cut instead of the blade being ever so slightly twisted over to one side . Then once it is cut through the top wall take the stock out the clamp and rotate it backwards to the motor end to get the cut vertical . The blade then has a vertical guide to follow . Slacken the blade off three full turns on the tensioner after each use session to reduce long term stress on the machine .
If I want a really accurate cut I do what my fabricator pal at Peterbrotherhood's told me to do . Cut over length then Dyechem the end & correctly scribe on the dimension ..use a 4 inch grinder or two to carefully grind back to the lines . Found this excellent advice especially when cutting 45 degree or other complex corner joints .
