Topic tags/keywords: bandsaw

I want to add a bandsaw to my “bag of tools” to supplement
the Hegner scrollsaw for curve cutting in larger pieces as well
as resaw/veneer cutting.

I have no experience in projects which
would make good use of the bandsaw in resawing/veneer and cutting curves,
so I wanted to double check with those that have experience so I don’t
buy something which I will quickly “outgrow” :

Regarding curve cutting:
(a)in the specs I see min blade width for saws whose wheel diameter is < 500mm
usually approx. 6mm is specified and for those with >500mm, 10mm is specified
(except saws like Jet -I think I’ve seen 3mm is min). I know the width of blade affects
minimum radius of turning, but would 10mm be OK if I went for the larger saw?

Regarding resaw/veneer
(b)Ideally infinite height of cut would be nice;), but what would be a
min you wouldn’t go under and max you wouldn’t go over ?
I have no experience with veneer and can only think of things like furniture/cabinetry parts
where you could use resawn/straight grained/stable wood of whatever width (height of cut)you could
get/but what would be a reasonable “quality” height of cut to look for from a bandsaw?

I’m in Croatia, so I don’t have access to all the saws mentioned here (nor the nice prices) but have possibility of getting hold of Jet, Hammer 4400, Felder, Centauro, Agazzani, Bini and Socomec,
with Jet and Hammer being the “light class” and others with dual quality guides
and heavier construction.

Hi Vjeko
I’ve owned a jet before the saw I have now and it worked well for a lower end saw. I usually use a 1/4” blade for cutting curves. As far as resawing veneer I would do some on line research like you tube. They key with resawing is to have your fence set to compensate for drift in your blade. I n all band saw operations it’s important to have a sharp blade so I would buy extras when purchasing your saw.

Hi Jim,
Is 1/4” (6,35mm) the min width stated for your saw (which saw do you have) ? Would 10mm (just over 6/16)
be OK (at least that is what is specified for the larger saws) ?

Had a look at your website (very nice!) – what about re-saw work -do you use the saw much
for this/do you often regret you didn’t have a larger one (not knowing how large your bandsaw is ;) )

Hi Vjeko
I do have a larger saw now but even though it is 5 hp and has a fence made to do veneer (called a driftmaster) I find that unless your doing very large pieces of wood that most saws with a sharp blade can re-saw fairly well.
Here’s a link for metric conversion.

Hi Jim,
You didn’t exactly answer my questions regarding:
- 1/4” / 3/8” width of saw blade
- what height of cut you would look for in a bandsaw – what did you need most
in your projects ?

These may sound like stupid questions but I just don’t know how big to go
(within money and space limitations ofcourse;)) regarding depth of cut and
am unclear on whether I’m loosing out in curve cutting (if specs are to be followed
i.e. smaller saw can have narrower blade) by going bigger

It depends what your making Vjeko
If your just going to make veneer all day then buy a resaw band saw with a big motor and resawing capabilities up to 16” or more. If your just going to resaw occasionally then the smaller Jet will do fine I think it can resaw to 11 1/2 ” . Most people in a general sense use band saws to cut curved or irregular shapes and occasionally resaw. A large Resaw type band saw usually uses large blades 1 1/4” or more but they are not good for curved work. In a smaller saw many can take blades up to 1” give or take. I hope this answers your questions.

I’ve found the best all around blade to be a 3/8” with 6 teeth per inch. Its on my bandsaw 99% of the time.

For re-sawing, I use a 1/2” 3tpi blade (mine is a Highland Wood-Slicer).

For cutting tight curves, I use either a 1/8” 6tpi blade, or 1/4” 6tpi (the smaller the blade, the tighter the radius).

And I would echo a1Jim’s advice … make sure the blades are good and sharp. Dull blades will contribute to burning, especially with blades that have more teeth-per-inch.

I’ve come across a couple new saws which have caught
my eye – would appreciate any feedback on my thoughts:

(1)Minimax S400P (I think this is a Centauro saw)
wheel 400mm/15,7”
depth of cut 400mm/15.7”
width of cut 380mm/14.9”
blade 10mm-30mmX0,5mm / 0.39”- 1,18”X0,02”
table 450X600/17.7X23.6”
weight 190kg/418lbs

(2)Minimax S500P
wheel 500mm/19.7”
depth of cut 500mm/19.7”
width of cut 480mm/18.89”
table 500mmX700mm/19.7”X27.6”
weight 260kg/573lbs

Now, (1) caught my eye as it has a much higher resaw capability
than other saws of this size (and width of cut would be good enough for
furniture/cabinet work) and it’s weight and size would
fit better in my small shop but the sales guy said he would go
for the larger one due to less saw blade breaking. According to
my logic, the longer blade (compared to others with this size wheel)
is travelling over the wheels less , with less stress on the blade,
and I guess blade breakage
depends on how good the blade/weld is/ saw setup and how careful you are.

The only thing still bothering me about it is not being able to put a blade narrower
than 10mm/0,39” on it for “scrolling” thick wood- but maybe
I’m expecting too much/will cover all fine work with the scroll saw.

Any smaller and I need to go to the Jet 14”
Any thoughts ?

Some recent articles I’ve read indicate that wheels of 14” are too small for the thicker (.032”) re-saw blades. The blades will break going around a wheel of that diameter. Plus blade drift occurs more in the 14” saws. Their conclusion is that at least a 16” saw should be used for re-sawing.

A 14” saw with a 2hp motor should do fine for resawing as well as curve cutting. For rewawing you’re going to want at least a 1/2” blade with 3 teeth per inch, you can still cut wider curves with this blade as well. For tighter curves a 1/4” should be narrow enough, though with a 14” saw you can get 1/8” blades for even tighter turns, but then can break real easy if you’re not careful. Even though a 14” has a shorter cut capacity, you can get a riser block to increase that. But like several people here have said, if you’re doing a lot of resawing, go with a larger saw.
