Jaw teeth suggestions wanted for vice for chainsawing

This shows the difference in 'grabbing ability' with the original 50mm on the left and the new 100mm on the right.

Now I just need 'teeth.' 🤔

Are you sure you're looking to build a vice for cutting tree limbs and not some sort of medieval torture device @Noyade? 😉

I'd start off simple with some basic toothed jaws. They'll likely to do a good job at holding a variety of different sized logs. Also, having consistently sized teeth will ensure that you don't get over-penetration of a single tooth and then have difficulty getting it back out of the log.

It would be best to weld up a solid jaw, but you might actually get away with two sections of steel angle with the teeth cut into them. I've added a rendering below. I couldn't help but contribute the second one. You know, just in case.

Keen to see how your experiments go. I think you should make a few different types and give us your review of them.

Wow! Thanks for the drawings - much appreciated! 😀

I very much like the top idea and I'll probably go with that with angle iron and connecting plate. Simple idea. Mine were becoming too elaborate.

I'll leave the bottom idea for the torture chamber.

Weather is turning miserable so I've quit for the day.

But so far I'm pleased with the extra clamping capacity.

Cheers!

Not a lotta progress today - weather was miserable.

I just cut the four pieces of heavy angle iron which will become the teeth - with my elderly Fastacut powered hacksaw....

At least you can sit down...

Thanks for the update on your project. I agree the weather was not ideal today, but between cutting the steel manually and using your reliable Fastacut I'm putting my vote for the Fastacut.

The Fastacut is now a piece of history I think. I remember my carpenter/builder father setting me up in a chair as a young boy with this machine and my job was to cut dozens of steel pieces for his work. I have a 14" abrasive drop saw but this machine is cathartic to watch/use and produces somewhat more accurate cuts, with less sparks and noise.

Problem these days is sourcing the blades.

14 teeth per inch.

Rapid progress. Better weather today.

Many thanks again Mitchell - your idea was much better than what I was originally gonna go with...

I'm not sure now if the jawed teeth should come together of if there should be an over-bite?

Dentists would say no.

One... One...

...or two.

Those teeth look perfect to hold large ungainly timber posts and branches. I'm sure a lot of our members will be looking forward to the final reveal once you've attached the metal jaws.

Please keep us updated with your progress, we look forward to seeing the vice in its final form.

Hi Mitchell and Eric.

"I think you should make a few different types and give us your review of them."

I thought about it but in the end I'm very happy with the concept you kindly devised above. But what I have done is tap various 8mm holes for high tensile bolts around the opposing plates so I can configure the teeth in various positions. In the lower photo I've positioned them to the extreme left ready to chainsaw wood into smaller pieces for a small fire bucket. The grip on even a small piece like this is amazing - I could never have done it with the original jaws.

The jaws when purchased had rubber ends - but over time they perished with age and snapped like a SAO biscuit and this inspired me to do something with the jaws other than glue more rubber onto them - which in reality was never any use to me as I never used it for delicate woodwork purposes.

I also welded a piece of steel plate to the back of the sliding jaw as you can turn it around to accommodate oversized objects - but even better now with larger dimensions.

I'm pleased with it.

Thank you so much for that photo update. That looks so handy and the best part is that you've made provisions for the jaws to go in the other direction if needed. Will you be spray painting it? It would be a shame to just let it rust or maybe cover it with some used motor oil for protection?

"cover it with some used motor oil for protection?"

Wow!

Great minds Eric! 😁

I only just did that before retiring for the day! 👍

Thanks for looking.
