Got a new bandsaw and decided to make some circles. Last bandsaw didn’t have a mitreslot at all, nor the ompf/tension to cut blanks out like this so it wasn’t worth it.

This required
  • 18mm ply scrap (I’m sure thinner would have been fine, but I had that on hand),
  • an offcut of hardwood,
  • aluminium t-track,
  • a bolt,
  • a washer,
  • a wingnut
  • and a shelf pin.

Pretty happy with the resulting circles/bowl blanks too! The photos of it have two coats of some shellac on it, which makes it so much easier to clean and slides/rotates a bit easier too.

Build video, with it in action at the end if you're so inclined

This is a very simple yet very effective project. I really like it and really want to make one now! I’ve not watched the video, but look forward to doing so later.

Can’t believe you’ve had so many views, and a favourite for this project, but no comments ‘til now! Seems a bit rude to me.

Anyway, thanks for sharing,

Garry

I have one exactly like it EXCEPT -

all seriousness aside – after watching your video, I’m inclined to go out to the shop and take a cordless DeWalt 20v Lithium battery powered saw and cut mine up.
The reason for that ?
My jig works but yours is so much nicer and has some well thought out features that I would (steal) incorporate into my new circle cutting fixture.
Thanks for sharing -
btw – the accent, is that Missiissippi ? Alabama ?

@albachippie Thanks – if you don’t have one, its actually really fun to use to see a perfect circle come out. Maybe thats just me though. As for people being rude, ehhh I’m just as guilty of that. I’ll favourite something but feel like I don’t have much to say :)

@recycle1943 Thanks! I think there is still room for some improvement for it to be the ‘perfect’ sled. It could probably have a microadjuster knob on the front stop block to accommodate for different blades or changes in tracking, a second clamp to lock it down once you’ve reached the centre point, maybe some holes in it to allow for dust clearance/extraction.

I think it gets to an effort/reward type thing – the t-track was ‘nice’ because it gave a lot of reward for actually less effort than making the wood equiv ;)

Oh, and the accent is Victorian (Australian) ;)

That’s a really good idea, Paul… appears to work quite well. Thanks for sharing! :)
