Any Buzzsaw Wheel Models for sale?

Had a little time to take a few pics and look at the gullet spacing and sizes. I noticed the outer wheel gullet openings have more slop built in than the inner wheel. What does that tell us? I believe all slight differences in the gullets are just due to hand cutting and filing them.

And a couple more.

Please note that the diameter of the nubs is about 1 inch.

Looking at your close ups. It seems to be telling us which direction the weight transfer is meant to go by the tapered edge. I drew some arrows for the direction of transfer as it looks to me.

You are happy and busy with it, but I have the strong opinion that the main objective for this design was to build a super flywheel!

Possibly with a type of energy recovery under lower/reducing rotation.

I don't follow you hammer.

Hi justsomeone

The extra slop would give a little more leeway (time) for the weights to swop
wheels.

I agree with you about the slight differences.

As a blacksmith I am very aware of metal wear and impact effect from many hits. The picture also tells me that the yellow outer side has been receiving heavier impact by the way it has less cupping while the red inner side shows little impact and wear due to being sharper. The other more curved part of the slot is wanted slop for more space to the transfer action. This also tells me that the red was moving faster than the yellow. Now all you have to do is figure how it was shifting the weights. The other unknown pendulum device that was talked about is the most likely system.

As a blacksmith, to make repair I would not file off the misshapen parts but heated them up and reshape them to specification. files would only be used last for clean up of possible unwanted chips and burs.

My theory is that the yellow part moved faster than the red part for leverage but the red part moved more often to catch up.

Thanks a lot for taking the time to take these photos JSO.

I made this Buzz Saw wheel using the Working Model Program a while back. I figured this thread would be the ideal place to share this. The weights, gear ratios, and WM settings are not set to any particular arrangement. You can add, move or delete the weights as you wish and change the inner and outer wheel directions (and gear ratios too). It’s also possible for anyone who is ambitious enough, to model a Geneva gear system, to add incremental movements of the inner or outer wheels. This may help with weights transferring and avoid binding if weights are caught between the two wheel sections.

I’m just a rookie when it comes to the WM program, so perhaps someone with better skills can improve the model and enjoy experimenting with it.

Quote from a bit back 'used as picking points to remove the cast wheel from its mold', not sure but if sand cast dont you just break up the mould to release? Even unthreaded it could be used for some attachment, say, a spung wire rod arrangment or device that clamps or can be tightened in/out radially?

I was once told the holes where where some additional mechanism was attached.
