Thread: Bandsaw swarf brush

My old Porsche metal bandsaw has a small wire brush for removal of swarf from the blade.
These are no longer available and to fit one I would need to adapt the round wheel ones that are now being fitted.

Did some thinking and recalled the bandsaw at the steel outlet which had cutting fluid nozzle after cutting.
Some others on another forum said that they have done this also and supposedly works a treat.
So I fitted one today.

Here's my baby BS fore and aft coolant.

I only fitted one extra nozzle. Will see how it goes.

Does your two work Bob?

I added a second fluid line to mine. Also changed the worn fixed wire brush to wire wheel. The blade now stays a lot cleaner.

Hi Tony, this is something I need to do for my BS too. Does that round wire brush rotate during operation?

I've cut mine back to one nozzle at each end and sometimes don't even use the rear nozzle.

Hi Guys,

I use a piece of carpet felt glued to the back mount. I just cut a slit in the felt with a Stanley knife and let the blade run through it. It collects the swarf and keeps the blade clean ! Actually the more swarf it collects the cleaner the blade is. I just brush the collected swarf off now and then. However I don't use coolant.

Thanks - that sounds effective and easily achieved.
I'm not quite sure what you mean by 'carpet felt' - a photo would be great.

I'm sure BaronJ is probably either having his afternoon nap or busy with the honeydo list at this time of day so I'll take the liberty of replying
I'd say he means carpet underlay felt - the older style underlay that isn't rubber/foam.

It was still commonly used in cars after most domestic underlay moved over to rubber/foam. My old late 90's falcon still had it, whereas I only ever recall using the rubber style in the late 70's when I did a bit of work with the carpet layer next door.

I was thinking about this yesterday or very similar anyways

Have the blade run though two adjustable insertion rubber wiper blades...one iether side of the blade..?

but for now I will just wait till i need to saw up steel and inspect as to how well the extra cutting fluid nozzle worked....dont want to fit another swarf brush or do anything at this stage until I have monitored it

Hi eskimo,
I tried a variety of brush set ups on my band saw and found they did not last long before they wore out. In the end I used a piece of the black poly tubing used for water irrigation. You need to find a piece the right internal dimensions to slip over your current coolant outlet and cut it long enough to fit down over your blade, you will have make a cut longitudinally and in the center of the poly pipe with a hack saw the same length as the blade width. Once this is in place the poly tube will deflect most of the swarf and the coolant flow will take care of the rest and lubricate the blade. I only have a single coolant supply on my saw mounted just after the cut and it works.

Just finished cutting some largeish bits of steel.

It has worked better than I thought it would.

Next to nothing in the way of swarf inside the arm and wheels.

Will now need to make a splash gaurd for new nozzle to stop cutting fluid splashing onto floor.

Sheesh...make something to fix something only to find you have make something else to fix what you just done...lol

Hi Guys,

Some pictures of my bandsaw blade wiper...

It is a piece of 5 mm thick carpet felt.

The felt is simply stuck on with a dab of Bostik. Its been on there since I refurbished the bandsaw, which is several months now. The debris simply collects where the blade runs through, I just brush it off now and again.

This is the carpet felt that I used. I bought a 20 metre long roll of it when I did my camper van conversion. I used it to line all the surfaces.

That's a simple but very effective method.

Like it.
