'Rope Blade' for bandsaw
 

Hi,

Trying to cut out jigsaws from plyboard with a bandsaw and was
thinking would
it be possible to obtain a blade for the saw that has a circular cross
section.

This blade would cut in all directions without the need to constantly
move and twist the uncut puzzle.

Does such a blade exist? I cannot fine one on the net or in my local
tool supplies.

Cheers,

Jack

Is there something like diamond wire that can be used in the band saw?
this is like a saw made from epoxy bonded diamond dust on a piece of wire.

Just a thought.

Seems like that might be pretty hard on the bandsaw tires

I've read about one, but IIRC it took special tires. I *have* seen
scroll saw blades that cut in all dimensions.

And poorly, too. With near zero turn capability within reach of a proper
blade, especially a bi-directional, since he's cutting ply, this blade is
going to be worse than useless.

yes. it's called a ring saw, used to cut glass sheet.

you can also get diamond band saws.

note that you have to use water cooling for them.

I've never heard of such a blade for a bandsaw but it is a common item
for a scroll saw, if all your are talking about is cutting out jigsaw
puzzles. The downside is that such a blade leaves a rougher surface
than a conventional blade, is slower cutting, and cuts a wider kerf.

A ring saw is different. Although most ring saw blades used for cutting
glass _are_ wire-like, that's just coincidence. The real difference
between "ring saw" and a woodworking bandsaw is that the ring is a
rigid ring whilst the band of a band saw is flexible. This allows the
bandsaw blade to take the usual "racetrack" shape of two semi-circles
joined by straight sections. Blades used for sawing glass aren't this
flexible, so they have to remain ring-shaped.

Glass working ring saws often also use a splittable ring with a screw
connector, so that you can saw internal cuts. Now _that's _a thing I've
often wished for on my wood bandsaw!

Everyway-cutting bandsaw blades are available, but they need machine
setup to be modified. In particular their guides are complicated by the
fact you're not just cutting forwards, so they now need to support the
blade against pressure every way.

As to the tyres, then they don't really care. So long as the teeth
aren't slipping _over_ the tyre, then wear isn't unusually large.

well, if you look at the 2nd link i posted, it's a real bandsaw,
although it's pretty small. they do have larger ones, but they're
majorly expensive.

there is also a wire saw that looks just like a scroll saw, but has a
cut in every direction diamond coated wire.

then again, a quick search shows a hilti saw that does this

On machine shop bandsaws, it's fairly common to have a blade welder
built right into the machine. One could drill a hole, cut a blade
open, pass one end through the hole, re-weld the blade, and do an
internal cut.

Not very convenient, but certainly possible.

No, they're both Tauruses. I haven't seen a Taurus 3 here in the UK yet,
but all the others were rigid rings, not bandsaws.

I was also warned off flexible band saws for glassworking recently (I
was looking to buy a ring saw) on the grounds that they didn't cut as
well "edge-on" as the thicker rings did.

Hello Folks,


Thanks for all the replys. I might try the scroll/fret saw baldes and
see how I get on.


On a different point, there is a terrible amount of S**t appearing in
the newsgroup
as I am sure you have noticed. A similar problem occured on another
group
some time ago but has since dissapeared. I believe it is like bad
weather, will
pass away eventually.

Cheers

The closest that I've seen is a bonded carbide wire for both hacksaws and scroll
saws, but not band saws, as it's used in an up & down/ back & forth motion..

Wouldn't a scroll saw be better for puzzles?
