See Michael Fortune's band saw videos, he adjusts the saw so you can use the saw fence with no drift. Worked perfectly on my bandsaw.
Wish I'd found this video before I wasted time on six others! Thanks, this is the best method I've seen so far!!
Thanks Rob! I have a Jet bandsaw with a 13 1/2” cut capacity, and have never been able to get a usable veneer with it. I tried again, following your advice, and ripped a couple nice sheets off for the first time. I know I’ve said it before, but thanks for all you do for the community. You have, most definitely helped “take my woodworking to the next level.” I’ll never get to your level, but the better I get, the more fun I’m having. Funny how that works! Take care Rob!
Perfect! Now I just need to buy a bandsaw so I can give this a go. 🙂
Hahaha. You just made my day. Thank you.
@@rickholmwood2000 youre easily pleased
@@gbwildlifeuk8269 your implication is what?
Great video! It’s nice to see you give some tips for using power tools more accurately.
Exactly the tip I needed today!
Really handy advice. Simply and clearly presented. I use a band saw at my wood working club. It's a professional machine used by a bunch of amateurs so you can imagine who it cuts most of the time. If it isn't a brand new blade then it drifts like a raft in a whirlpool. I'll be using your advice next time.
Wow. Great tip Rob. Thanks 👍
Nice tip Rob. My bandsaw at times has a mind of its own and cuts all over the place but not what I want.
Thanks Rob, just what i needed.
Thanks Rob. Solved my bandsaw drift.
Thanks Rob. Years ago I built a fancy resaw fence from a woodworking magazine. It work and has all kinds of adjustability but it gives me fits a lot of the time. Looks like all I need is a good straight edge. I wonder how a piece of angle aluminium would work. Not an expensive option at my local scrap yard. It would remain stable in my changing shop environment. Love your technique.
Thanks a lot for the effort and explanation.
Thank you Mr Cosman!
Using the fence and accounting for blade drift is a good idea. Great video thank you for sharing!👍🏻
Thanks for watching and commenting
Once u find the angle the blade is cutting at loosen the table and adjust it to suit. Then you will have the tables mitre slots and the fence matching. Saves finding your blades cutting angle and clamping wood on the table.
I suggest aligning the table (and miter slot, and fence) to the blade. This would correct the cause.
Very helpful video, (as always). Thanks Rob
Thanks for watching
Great idea.
Great! I have been wondering about that.
Thank you 👍👍
Excellent tip! Problem solved!
Nice !
I'm catching your drift, tks
Thanks. Any thoughts on doing a bandsaw blade sharpening video?
Thank you. This is a really handy video. Do yo think that if you aligned the the stock fence to the block of wood it would stay true and avoid drift? I have always found my stock fence problematic for this same reason.
Thanks
Thanks for video. I’ve been going crazy over the drift. I use a Laguna 1412 and generally love it but I’ve been getting drift of 1/100 to 3/100 over 12” length and trying to correct for that. Now I think it’s just my OCD. Maybe some drift is normal
does a too-tight blade affect the cut, or just cause extra stress on band and bearings?
Do you need to sacrifice part of the thickness of the board that you want to slice? Can you use another board that may not have identical grain direction relative board thickness? Can you use a pine 2x4 to establish drift before cutting 8" wide (8" tall on bandsaw) hardwood?
Does this drift vary based on the hardness of the wood or height of the work piece or can you set-and-forget it and cut many pieces of differing heights and species?
Hope you're feeling better!
Rob
Enjoy your videos. Does the drift always stay the same (using the same blade, tension). If so couldn't you just adjust the actual bandsaw fence and be done with it?
Have you any experience using Michael Fortune's technique of setting up the table to the drift? I used his method and squared up my table, now my mitre gauge works with the blades. I have tried all 3 of my blades and they use the same setting with equally good results. I have used the method you describe in the video, which does work great, but with the table set up, there is no need to redo your fence set up every time.
I've seen that Michael Fortune video and admired his approach. Been shopping for a bandsaw online, but I want to ensure that lateral table adjustment capability is available on whichever saw I end up buying.
@@kennnva551 I think most"new"bandsaw have this. I think it is called a trunnion mount?
If you adjust the table so the miter slot is parallel to the blade you will eliminate drift and you will be able to use jigs in the miter slot and know the angles are correct.
What would you consider a good size and tpi for all-purpose bandsaw blade?
Usually have a 1/4” 3tpi blade in for general purpose because you can take tighter turns. But I wouldn’t be cutting into any thick hardwoods with that blade! 3/8” is a good compromise and I’ve had that size every now and again
My blade twists to the right as soon as wood touches it. How do I fix that. Is that the same as drift?
I understand what you are saying but I have a question. Why do manufacturers put a tall fence on a band saw if you can't use it?
Pop Walker
So you have a thin slice, with one jointed side, and one sawn side. What's next for the sawn side? Plane? Or the jointer? Or leave it as sawn so that the glue has a rough surface to bind to?
I plane it, lay down a piece of sticky backed sand paper to hold the veneer in place while I plane the rough side.
Hi Rob, wouldn't this work just as well if the fence had been set up parallel to the blade in the first place? Mike
The blade twists and turns while cutting, that's why he did those first few inches by hand to determine the angle.
@@mitschkoff Yes I understand this but if the permanent fence is correctly aligned with the blade I don't understand why Rob's temporary fence would be any better.
2:57
As you use the blade particularly on cutting curves, the set wears unevenly. Now it may no longer cut parallel to the fence.
@@RobCosmanWoodworking Understood Rob, thanks. I guess that would apply mostly with the narrower blades. As I don't have a table saw I use my bandsaw mainly for resawing and long rips with wide blades
Good tip.
However, the thickness discrepancy is 20 "thou" - about 0.5 mm. It's about 25 percent of the thickness of the panel!
Rob, I have trouble keeping an even thickness to top to bottom just resawing. Forget about slicing for veneers. What do you think the problem is? I am using a 3/4 inch woodslicer blade. Used the Alex Snodgrass method for setting up my Grizzly bandsaw. I cannot seem to get an even thickness top to bottom on stuff over say...6 inches tall. Is this a blade tightness issue? Thanks.
Yes tightness would be my first guess
@@RobCosmanWoodworking Thank you.
Could it also be the table isn’t 90 degrees to the blade?
@@TWC6724 as I mentioned, I did follow the Snodgrass method for setting up the saw, the table is square to the blade.
@@RobCosmanWoodworking is there any good way to determine if you have the correct blade tension? Any kind of trick you use? Alex says to push on the blade at a certain location blah blah blah but that is so subjective.
Grazie!!🔝👌🤗
Thank you for watching and commenting
If the band saw table is properly aligned, you don't need to do all of this. And that it relies on sawing to a line, then aligning an auxiliary fence by holding the board in the correct position? Just align the table correctly and put the blade in the correct position on the upper wheel.
Hi.
What happened to your voice?
Thanks for these tips.
Dads got a cold
Just adjust your bandsaw correctly. This technique is fine once and a while but not practical for everyday use.
Forgive me if this is a dumb question (I just purchased and set up my first bandsaw 3 days ago - Rikon 10-326). Does this technique work for any resawing thickness? In other words, does this work if I want to resaw a 1" thick board down the middle? I just tried this a couple hours ago using the fence on my saw on a piece of 9" X 12" red oak. It came out pretty good, but definitely not perfect.
Why not just adjust the alignment so the blade is riding properly on the crown on the wheel....
ripping??????? NO! this is resawing NOT ripping. thanks for the info!
Are you a trumper?
I just use the right blade and tension the hell out of it. That blade has too many teeth per inch. Way too many. I'd put a1 inch, 2 TPI, carbide, Lennox woodmaster on that saw. It's big enough to handle it.
It’s a 3tpi skip tooth, for the amount of re-saving that I do it has just the right amount to make it useful in other applications
@@RobCosmanWoodworking Aside: I bought your book on DT.s Thanks for that.
I've never seen my saw drift. Online discussions (that I've seen) on it seem to revolve around (1) tiny saws that can't develop sufficient tension, (2) worn-out blades and (3) blades with insufficient gullet to clear the chips. Your saw looks plenty sturdy. I bet you don't have drift either.
Waste of time … a properly aligned bandsaw DOES NOT DRIFT. Watch the video by Alex Snodgrass on the topic. My 14” Delta with a 1/2” Woodslicer blade does better than that.
Ok professor.
Why are you guys propagating bandsaw drift. IT DOES NOT EXIST. please learn how to set up your blade and the drift will disappear

Nice!
