Cutting hose-ends square

[Shoalwaters]

I try to cut the ends of new hoses clean and square. Short pieces can be cut on a mandril in my lathe, but anything over 14" long has to be done with knife and eye. This seldom results in a square end, especially when cutting waste hose with spiral nylon reinforcement. Google has only turned up variations of scissors and guilotines,* both of which squash the hose first and will (I think) produce an out-of-square end. A chop-saw will cut the black steel-reinforced hose, but it melts anything plastic. A device based on a tubing cutter with a mandril inside the end of the tube might work. Any ideas?

When I have access to one when I want to cut a hose I use a bandsaw.* On the boat I use one of those hose-cutting tools, the kind with a handle and a blade attached to a pivot that you squeeze to bring pressure onto the hose.* I have found that by putting on a small amount of pressure and then rotating the tool around the hose I can cut thruough it without compressing the hose itself, and the cut comes out very "square."

But the bandsaw is best.* I just don't often have access to one when I have to cut a hose.

Mike: I've used one these for cutting waste hose and even 2/00 battery cables. You can re-sharpen the blade or buy replacements. I'm not sure about the steel reinforced hose.

If cutting the hose with a handsaw, I'd first run a strip of painter's tape around the hose to mark the cut.* Once satisfied with the squareness of the tape, use it to guide your cut.

Ive always had good luck with a serrated knife. So if you don't have the right saw or other tool blade, a quick trip to any Dollar Store for* a serrated knife can save the day.

Peggie,
Those things ALWAYS cut crocked. I hate them. But they saw good.

If I know how long the hose should be ahead of time I'll cut it on the horizontal bandsaw in my shop.

When I'm on the boat I do this -

I buy the cheapest little plastic yellow miter box I can find - usually 6 or 7 bucks at a place like Ace. I cut the hose in the miter box using a nice rigid (small r - not a brand name) square tube hack saw with a fine blade.

I use KY jelly to lubricate the blade. Easy to wash off, and really speeds the cutting up. I just clamp the hose with my free hand.

If it's a big project I just throw the miter box out when I'm done - they don't last long, but it does give a nice almost square cut.

As square as hose needs to be anyway.

Works for me.

Make that vote #2 for the cheap miter box and a hack saw. *Pipe cutter pliers are great too- that is typically what I use.

I second the recommendation for the pvc pipe cutter.
Mine is redline brand they come in two sizes to cover various size pipe works a treat
cuts square only 1 reservation later model ones seem to have gone to plastic for the frame mines cast metal and durable dont know how the plastic frame works out.

This is what I use:

Works great on any hose, rope, etc.

Here are a couple of others.

Mike, it looks like lots of good ideas for getting a square cut, but I wonder why it needs to be so perfect.* I would think, that unless it's really out of square to the point you can't double clamp it, it makes little difference.* Still, there are some good ideas here........Arctic Traveller

Glad someone else ask this as I am wondering the same thing.

"Glad someone else ask this as I am wondering the same thing."

Yes. I guess one can make a project out of any task.

 

[Shoalwaters]

Thanks to all who responded; plenty of food for thought. The tool I thought might exist apparently doesn't.*

The last three posts ask why it has to be "so perfect". My requirement is "clean and square", in other words to good engineering practice. That includes bolts and hose clamps of the correct length,*cable ties with the ends clipped off and screw-driver slots lined up. It may be a tad childish, but I get satisfaction out of looking at a finished job done to the best of my ability.

I used to work with a mechanical/automotive engineer Brit who was an ex Cat rep, car builder, etc.; a really serious, knowledgeable guy.* He showed me a photo of a working steam engine model he had built.* I commented on the fact that all the screw heads were lined up in unison.* "Full marks for you, mate!" he said, beaming.

The fact that somebody noticed absolutely made his day. So, I can relate.

I have not thought about cutting them square if there is enough room to get two hose clamps on, so what is the diff its square of not square?***Shoot most of the time I am just happy to cut the hose and get the hose on/off without cutting/hurting myself.

Does that also include filing the ends of clipped cable ties?* I can't believe how razor sharp that plastic can be.* I try to file them if I can, but at a minimum I'll take something blunt like a pair of pliers, and pound on the sharp corners to dull them.* I'm tired of cutting myself on the stupid things.............Arctic Traveller

Try cutting wire ties with side cutters designed to cut plastics.* Very sharp, no bevel on one side, leaves wire tie ends square with no points.

McMaster and most tool retailers will sell them:



<h3 class="PrsnttnNm">Plastic-Cutting Pliers</h3>

With Adjustable Stop and Cushion-Grip Handles






Designed for cutting plastics, these extremely sharp pliers make a flush cut that leaves a smooth, finished edge. Not intended for cutting metal or wire.

Normal people* believe that if it ain't broke, don't fix it.*

Peggie,

There's only one "ain't broke" line that flies.


If it ain't broke it must have been maintained.

Hiya,
** P/F.* One of the reasons Mr. Shoalwaters lines up his screw heads, uses the proper sized clamps*and tidies up his work is*a concept called PRIDE OF WORKMANSHIP.* Doing a half-assed job isn't in MY maintenance program either.* Well done Mr. Shoalwaters.
** Mr. AT.* I hear ya about the sharp ends of cable ties.* One of the things I do is hit the cut end*briefly with my soldering iron.

There's a big differerence between "fix" and "maintain."* The line is, "If it ain't broke, don't fix it."** It's not, "If it ain't broke don't maintain it."

 

[ColonyCove]

I'm not going to vote on whether a 60 degree jagged crosss-section*hand-cut with a dull kitchen knife or a laser guided precise 90 degree cut made on your CNC milling lathe is superior.* It's entirely a matter of what's good enough on your boat.
However, for those seeking something approaching a square cut, consider a piece of dowel closely matching your hose interior diameter being used to prevent hose collapse while employing your mitre box or hack saw.

 

[sunchaser]

Form over function keeps too many vessels at the dock. Lining up screw heads in an ER takes the cake. But, OC on boats*is alive and well and keeps therapists in $$ to pay for their own toys.

And another thing.* If I was in the market for a particular boat, and found two similar, all other things being equal, the one with lined up screw heads, proper sized clamps and bolts and a clean engine room would make me believe that boat has received better maintenance.* Which one do you think I would buy?* It's the reason I keep my engine room immaculate, my maintenance records complete, and my manuals up to date.* Better resale value...............Arctic Traveller

These sound great, have you used them on zipties?* It seems to me the sharp edge that results from cutting with normal side cutters is the corners. The edges end up razor sharp. Does this tool eliminate that problem?* If so, I'll be getting a pair soon................Arctic Traveller

 

[Forkliftt]

Radioshack sells a $5 pair of red handled pair of light duty side cutters that is flush on one side and tapered on the other- similar to a wood chisel. It is great for clipping tie wraps so long as they are not the huge ones.
