I finally got myself a 26" bandsaw!! Now it will be a nice addition to my shop, but the crap 14 inch bandsaw has got to go. I was told I have to move out by the end of september due to my shop being recalled by the government due to rezoning.

Here's some picture.... bicycle tire as scale reference (it's a 26" bike tire). Bandsaw uses a big handwheel for adjusting the height of the upper wheel, but the tension is held with a weight besides the saw. Meaning I need to find a way to lift the weight in order to change blades. I'm thinking of using a pneumatic cylinder that I got off of a neighbor's CNC machine to replace the weight with something a little more controllable.... The cylinder was malfunctioning due to a worn out seal, and the neighbor who owns the CNC machine bought a new one and threw the old one out. I may be able to use it to hold tension and vary it based on air pressure... But anyways the saw itself uses a weight hanging from a lever, using the mechanical advantage to actually apply tension. If you need more tension, add more weight.

These cuts were done in 10 minutes flat, on a dull blade. Looks like the Acacia finally dulled the blade too much... I think bimetal/carbide is better served here. Probably Woodmaster CT or Woomaster B...

Paid about 1000 dollars for the saw, purchased with my tax refund from 2017. Thank you, IRS.

Most small to medium size bandsaws are tensioned with springs and handwheels. I don't know why anyone would use weights. I do have a friend who uses weights as a power feed for resawing to pull the wood through the saw. trange process, but it works for him. I think I'll stick with my electric powerfeed and spring tensioned resaw.
