I have a Laguna 14-12 bandsaw, and was just cutting down some logs for a spalted box. I noticed the blade was moving a LOT, and got some REALLY crooked cuts:

After cutting them all, I noticed the table insert was cut into as well:

My blade tension is set appropriately, does anyone know any other suggestions for things I could adjust?

Do you have your guides set correctly? That’s probably a really dull blade or kinked blade as well. Did you use your resaw blade for cutting curves? You should dedicate one for only sawing straight lines.

Regardless, after cutting your metal insert, your blade is probably dull now anyway. Time to replace.

What blade are you using? I have that same saw and had a similar problem, then I switched to Timberwolf blades and the problem went away immediately and completely.

I had a lot of difference just by adjusting blade to run with bottom of teeth at the midle of the wheel.

pmayer thanks for the advice. Can’t remember what the brand was on the blade I bought… it was from Rockler and I purchased it last year. We (the classes I teach) only use it for straight cuts, we have a different saw all together for curved cuts. That doesn’t necessarily mean that a student didn’t mistakenly try to cut curves on it.

jmartel I used the standard setup that was shown in the O.M., this is what it looks like now, after some use:

any suggestions on things to adjust?

When you are resawing, you need to have the guides about the thickness of a sheet of paper away from the blade (both upper and lower). There’s way too much play in that photo.

Replace the blade, move the guide blocks in closer, and you should be good after that. Note that you will need to move the guides when you cut curves.

Look up a video on youtube from Alex Snodgrass for tuning up your bandsaw. Once I followed that, I could peel off 1/16” veneers straight off the saw.

I’m no pro, and I don’t have a laguna (griz 17) but the guide block on the left looks like it is way too far away from the blade.

When I setup I use dollar bill folded in half to space the blocks from the blade (less than 1/32”). Your image looks like is almost 1/8” or more away. I do this for both top and bottom

Hopefully someone with much more experience will concur. If not I may learn something new.

its the guide block that’s confusing me… I looked all over the place but it doesn’t seem to have an adjustment for moving the white inserts closer to the blade.

Hello Tooch, the Laguna guides are made of ceramic and the blades from Laguna have zero pitch, the blade runs right to the guide. Looks like you have corrected the problem, have fun, make some dust.

I have a delta 14” and do a lot of this resawing and i found that a 3/4 x 3 blade works the best.

One day the blade was dull so i did an experiment. I put a 3/8 dia grinding stone in my dremel and
blowed alll saw dust out of saw and used the dremel to sharpen the hook part of blade,it only took
about 15 min and cut like a new blade so i made it a practice to resharpen the blade. just hold the
grinding stone in the hook of blade and move dremel in and out. it don’t take much to sharpen
and saves a lot of time and money.
