I just began testing my skill with cutting thin strips on the band saw for a project, not a veneer just some edge banding. I curious with shop cut veneers it seems very difficult to get uniform thickness considering the blade drift and user variables:eek: . My bandsaw is not yet "tuned" as it might need to be for this type of work.

Is it pretty much mandatory to have a drum sander available for thickness sanding when you get ready to veneer a panel with multiple pieces of veneer?

I'm not yet ready to attack a veneer project but I'd like to sometime and want to know a bit more about what I should expect.

Is it pretty much mandatory to have a drum sander available for thickness sanding when you get ready to veneer a panel with multiple pieces of veneer?The answer, as usual, is "depends". If you're not trying for a perfect book-match on the adjacent pieces and you don't mind losing a bit of material, you can substitute a planer for the drum sander:
1. get your stock smooth/flat
2. slab off one piece of veneer
3. run the remaining stock through the planer to get the sawn face flat/smooth again
4. repeat steps 2 and 3 until you have what you need (or run out of stock)
The key to this is that each piece of veneer has one smooth face: that's the one you glue down. The top face will have the usual saw marks etc and need to be smoothed, but that's usually somewhat necessary anyway.

Note that I didn't say this method was easier (or better) than using a drum sander, but a planer is a lot cheaper.

And of course how well your bandsaw is tuned and how good your blade is matters a lot.

I do a lot of shop sawn veneer work. "Blade drift and user variables", are the things you want to eliminate as much as you can. I have a dedicated resaw machine, power feeder, and a carbide blade, but I still feel the need to sand the veneers smooth for a consistant thickness. I have the luxury of a drum sander and so I use it to acheive a perfectly flat and smooth veneer.

But all of this is not necessary to creat shop sawn veneers. I agree with all of Lee's recomendations above, and I suggest you tune the saw, adjust for drift, and work on your technique. Good pressure against the fence and a consistant feed rate will improve the quality of the cut and reduce the sanding requirements.

Lee, your approach sounds like something I've started doing. When I was cutting strip for edging, I would return to the jointer to give the rough edge a pass and then return to the band saw. This way I always had a clean side that I used for glueing.

I guess just substitute the planer for panel resawing and it's much that same.

I do need to work on tuning the bandsaw though.

I have recently cut some veneers on my bandsaw using a 3/16" x 4 TPI blade. Gave very consistent thickness at about 3/64". I did not try to plane between cut because I was just testing the blade combination. I was actually surprised at how consistent the pieces were. I got 10 veneer pieces out of a 3/4" piece of walnut. If you want to get a smooth face, then you will lose some when planing and cannot get bookmatching since the smooth face is always on the same side.

So John, when you coming by the shop and setting up my S45? :D :D Bring your drum sander with you too, OK? :eek:

I was fortunate enough to have a bentwood lamination class with David Marks last week. He tuned a bandsaw that he had never used (the same saw as I own) to a level that cut consistent strips of wood for bending, roughly 1/16" x 3/4" x 3'. The thing is, he did in 15 minutes what I haven't done in a year and a half. I now have a renewed belief that a tuned bandsaw can produce glue-ready parts.

Not sure I can do it, I just know it can be done.:)
