Designing a Log Cutting Mechanism - Get Suggestions Here

[andrewtirtawijaya]

Good afternoon guys,
I want to discuss with you guys a few things...
So i already design a log cutting mechanism as you can see in the picture below. But there is so much defect on my mechanism..
The biggest thing that stressed me out, its still uneasy to use because after cut the log, the user must lift the blade, move the log, and put down the blade, and start cutting again. Do you guys have a splendid suggestion about how to make it ease without changing the big idea of this tools? And how about locking system that prevent the blade to go down when we don't want to cut the log/ finish cut the log.
Thanks a lot guysss for your suggestion.

What does your illustration represent?

From top to bottom, there's a T-handle on a round, unthreaded rod going to a square block. This block is about halfway between the top of the machine frame to the bottom. What does this do?

Three brown dowels (logs?) appear to be held by rectangular plate (with three matching half-circles on the bottom edge) at the bottom of the frame. Is this a hold-down plate, or is it supposed to be the blade?

That does not look like a practical design at all to me. Is this for a schoolwork ME design project or something?

And if for real-world use, why not just use a hand saw or a chainsaw? They both work pretty well...

If you have to make that, you could drill a hole in the blade and secure it to handle. Set screw/spring pin in the top bar to keep blade/handle up when not in use.

Cutting logs across the grain with a blade is very hard, however it's much easier along the grain. Something similar to your idea is already used for this. Google hydraulic log splitters.
