« Part 7: Wheels Part 8 of Homemade Band Saw series Part 9: Bandsaw running... »

This was my first time turning the bandsaw on. So far so good. In my previous blog entry I stated that I might have to remake the top wheel – from the video you can see there’s a pretty good amount of wobble in it compared to the bottom wheel. I’m not sure if this will effect the performance or not since the wobble doesnt effect the crown of the wheel (you can see the blade stays nice and straight).

It’s a little loud right now because I dont have the rubber around the wheels yet, and there’s a clicking in the drive belt because it isnt tight enough.

It felt good turning it on for the first time! I can’t wait to finish it up and get using it!

The video isnt embedding like its supposed to. Here is the youtube link http://www.youtube.com/watch?v=0Z8vZniiQ1c

Very nice saw, it is a great feeling to see the saw run for the first time isn’t it? :D I built the same saw, You really have to make sure that there wheels are balanced as good as possible, what I thought was good ended up vibrating the saw a lot. After a little re-tuning it was fine.

And for the wheel wobble, on the bottom wheel I returned the crown when I had attached the wheel to the saw. I just set up a makeshift tool rest, it got rid of all the wobble for me.

the crown stays centered – thats not the problem. I think the problem is that there’s some warping in my wheel. I turned the wheel with the warping already present so the crown does stay centered. I’m just worried that the wobble in the wheel will cause too much vibration. It doesnt seem to at this point, but I’m not sure about in the future….

Hi Doug, nice going so far. That is a neat looking saw. I am amazed that that blade stays on the crown. Most wheels are flat with a big rubber band around them.
I had a crazy idea but it might work. If a fella were to set up a tool rest in just the right area so as not to get in trouble from the blade, you could take light cuts on both wheels with lathe tool from both sides to true them up. But if the wobble is due to wood movement, it may come back when the humidity changes.
With the wheel wobbling, does the blade itself wobble. it did not look to be in the video!

Hey Jim. The blade itself does not wobble because it stays on the crown of the wheel! So I dont think the wobble of the wheel effects the blade. I’m really just worried about vibration of the whole bandsaw, and maybe with that wobble the wheel might wear down faster? Not sure….

I’m guessing that with the wood wheels directly contacting the blade, there’s not enough tension across the contact area to move the blade laterally so it’s just staying relatively centered on its own.

Although the blade itself would have a different spot contacting the crown at any given time, so it wouldn’t have consistent support behind any one spot on the blade. I’d wonder if that will cause a less clean cut when you run something through it?

Scott. Woodgears has a great video on why a belt (or blade in this instance) stays on top if a crown. Here is the link – http://woodgears.ca/bandsaw/crowned_pulleys.html

The crown on the wheel does not wobble. I turned the wheel with the wobble already present, so the crown is stays perfectly true. You can see in the video that the blade does not move at all

Ah sorry, missed your comment about the crown being turned afterwards. So everything important about the setup is straight. I guess that shouldn’t be a problem then.

Youtube embedding has been disabled, something to do with spammers.

Nice progress on the wheels!

looks like it is smooth running, in order to change the belt do you have to take off the blade?
