Default Blade question

Having issues cutting these bandsaw boxes so I thought I would ask here.

Doing the resawing I have no issues I get straight and even cuts, but when I change to the 3/16-4 tpi blade to cut out the shapes I can't get it to stop the chattering I will be cutting fine then it all of a sudden starts this chattering which make the kerf wider in that spot. I've tried different tensions on the blade, and it doesen't seem to make much of a difference.

Anyone got any insight on this?

Thanks In Advance.
Danny

I have the stabilizer and the blades is there's also. not sure what the issue is. Course I'm cutting hardwood, they use soft wood at the shows to demo the products. ;-)

How much blade is in the wood when it begins fluttering and how much force/pressure are you putting on the blade as it moves through the stock?

Is the chatter at the top, middle or bottom of the stock where the kerf gets wider?

At the top? Maybe dullish blade, slows down in the cut which causes the tires to compress and suddenly there's more blade above the stock trying to get in than at the base trying to get out.

Some times I get the same kind of thing, (wobble) in my TS when I'm pushing wood with mental grain too fast through the blade.

Never bite the hand that looks dirty!

the guide is just above the stock, the stock is 5+" the chatter is the full length of the stock, I've tried different push forces, going slow fast; and the onlything that will stop it is to stop pushing all together then start again.

If the blade is sharp you should not need to push, that's to say not to hard, it should just walk the line easy.. hardwood or softwood..

Not really pushing more of just guiding, like I said not sure why the blade does this. Kind of a PITA when you need the kerf to be small and smooth as possible and you are using both peices.


I have two blades from them (Carter) I think I will try the other blade, it just might be that blade. I have 5 more boxes to cut the drawers out, cutting the outside shape is not a problem since I can adjust so the peice I want has a good cut but the drawers have been tough. Sanding out that chatter makes the kerf big then (or is it than ) I have to adjust the rest to match.

Maybe I'll go back to making boxes the old way "with several peices joined to make a box"

How are you tensioning the blade? Are you using the flutter method?

.
Never, under any circumstances, combine a sleeping pill and a laxative on the same night.
