Default How do I cut reinforced silicone hose?

I didnt know what section this goes in, so move it if there is a more appropriate place.

I have a lot of reinforced silicone hose that I need to cut. It's reinforced with 4 plys of polyester. I'd grab a pair of scissors, but I need to make over 100 cuts.
Also, these cuts need to be clean.

Is there any way to do this with a bandsaw?
Is there any specialty tool for this?

I'm afraid that there will be too much flex with 2.5" ID.
Anything?

Thanks,
Alex

Check at your local Auto Parts store for a hose cutter.They work great on radiator hoses.

Maybe a set of Craftsman HandyCuts or similar. Sears item #00937301000 Mfr. model #37301.

Not sure how thick 4 ply polyester reinforced hose is but its what I use for most radiator hoses, heater hoses etc. If it was wire reinforced like fuel filler hose I would use an abraisive chop saw.

Do you think it will have trouble with the polyester braids?

I'm guessing that you probably have a chop saw if so use it. Just be ready for smoke from the hose. If you have a miter saw I'd give that a try and see how it works. At work we have a tool that clamps the hose flat and has a blade mounted on a slide to cut the hose. It is used for rubber radiator hose, the straight stuff that's a ***** to cut any other way. Hope some of this helps.

Yeah, we've got an Ellis saw at my shop, but I'm thinking our blades arent fine enough to make a clean cut. They're made to cut stainless steel and whatnot.

Is this clamp you speak of called a vise grip?

It's a flat table about 7 inches front to rear and about 8 inches wide. There is a arm that pivots at the rear to clamp the hose and it's held by hand. The blade is mount to a piece of keystock that slides in the base. The keystock has a knob mounted on the end about 3" in diameter to push the blade. If I remember correctly it was made by Gates rubber company. I havent seen it since this spring, hopefully it's still around so I can get some pics for you.

I've cut all sorts of rope with mine so I don't think it should be a problem. The main thing is that your hose isn't too thick. If it is too much over a 1/4" wall the blade isn't thick enough. Basically it is a razor blade and anvil integrated into a set of pliers. The hose cutter pliers should work good too. As Dr. Dean alludes to, flattening the hose while you cut it should help.

If you are doing a whole mess of them ie. production run, I would look at rigging something up. With a new blade your Ellis saw may not do to bad. Otherwise something with a blade and anvil type arrangement should work good too.

Do you guys think that if I clamped the tube flat and used this 52tpi blade it will work smoothly?

clamp it flat then cut next to the clamp block with an olfa razor knife use
wd 40 as a lubricant. Use a wood bottom block and an aluminium top block knife guide. when the blade dulls just snap off the section and you have a sharpe blade. Terry
