• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Bandsaw kerf

I'm in the process of making my first small box and I've just glued it all together and I'm ready to cut the top off. I checked the kerf size on my bandsaw to compare it with the table saw and the table saw seems the better choice. Although the bandsaw blade is only 1mm thick it has a slight side to side vibration which leaves a kerf of 2mm (and a surface that needs sanding). Can this vibration be tuned out?

The reason I ask is that I've seen a lot of recommendations to use the bandsaw for this as it reduces the impact on the grain continuity but that doesn't seem to be the case with my bandsaw.
 
Assuming your bandsaw is set-up properly, I'd buy another blade.
 
How wide is your table saw kerf. 3mm is fairly typical I think, but there are narrower kerf blades.

The other thing to factor in when comparing the two is how clean the cut is as that will dictate how much more material needs to be removed in cleaning it up (e.g. with a hand plane).

Definitely and also whack up the tension on the blade to max until it's righty-tighty - Rob
 
Too tight is almost as bad as too loose on a bandsaw blade.

When you start to tighten a blade, watch from the front edge. It will vibrate a lot. As you slowly tighten the vibration will lessen, and suddenly become so still youll think the blade has stopped turning, Thats the correct tightness. If you carry on tightening the blade will vibrate again and the cut will be bad.
Of course that assuming the blade has not been kinked from abuse.

I've used both bandsaw and tablesaw, and both are about equal provided the blades are in good condition. If using the table saw I would use a sacrificial piece of wood to push it through as the only damage you will get is as the blade exits the wood.
But just to repeat, ether way, the blade must be good.
 
After a quick google it seems you should be able to get a blade with a kerf under 1mm and possibly as small as .75mm. I’d have a chat with Ian at Tuffsaws and see what he’s got.

The blade I have in it is from Tuffsaws although it has been resharpened once fairly recently so that could be the problem.
I'll check the tension but I don't think that's the problem and I'll chuck a new blade on and see if there is a difference.
 
I've had blades resharpened, they never cut as well so I dont do that anymore.
