If you’ve ever had the pleasure of owning a band-saw you’ll know exactly how much fun it is to try to replace the blade, or properly tension it even. [Richard T] got tired of it and decided to upgrade his band saw with a bit of pneumatic power.
To remove the band saw blade or tension it you have to turn an adjustment knob on the top of the band saw — it’s kind of awkward and really annoying. [Richard] has taken the lead screw out and replaced it with a pneumatic cylinder. He’s added a little control panel with a main valve, and pressure regulator. To remove the band saw blade, he bleeds the system with the valve, and to tension it, he turns up the regulator! It’s simple and super effective.
This is especially convenient for tensioning because you can watch the blade during the “Flutter Test” while gently turning up the regulator.
If you look in the right places you could probably build a system like this for less than $50. For a complete explanation stick around to hear it from [Richard] himself!

Still looking for that perfect gift? [Joel Witwer] shows us how to make a log coaster set and holder on the cheap. He figures he spent just $5 on the project and from what we can tell that all went to some polyurethane which he used to finish the wood pieces.
It started with an interesting-looking and appropriately sized log which he found on the side of the road. We’re not sure about the ins and outs of drying stock to ensure it won’t crack, but we hope he took that into account. With raw material in hand he headed over to the band saw. The cutting starts by squaring up both ends of the log while cutting it to the final length. He then cut the bottom off of the holder. What was left was set upright so that he could cut the core out of the log. This is the raw material from which each coaster is cut. A spindle sander was used to clean up all of the pieces. The last step before applying finish is to glue the bottom and sides of the holder back together.
[Joel] gave some tips in his Reddit thread. He says you should hold on tight while cutting out the slices for coasters because the round stock will want to spin. He also mentions that some of the slices aren’t as flat as they should have been, something to think about if you’re cutting these for yourself.
Thinking of buying a new bandsaw? Stop it. Make one instead. Not only could you save some money, you could customize it to be exactly what you need. There is a step by step breakdown of the entire construction with tons of great pictures. He even has some great info for general bandsaw use if you’ve already got one.
