Cutting macro line

[Glovebox Operator]

Is it better to cut ever so slightly longer or shorter? I never seem to cut on the correct side of whatever line I've measured, so which way is it better to be wrong? Also what is the best tool you've found to cut with?

I usually aim for just right. Something sharp.

jk. I do try to hit just right. Sometimes error on a little long. Have one that’s a little short and I need to adjust it on occasion or it leaks. I use garden shears to cut macro.

Ha I usually do too. Last one was cut twice and still to short. The coolant/ fuel line cutter i use does a pretty good job but pinches it a bit. And a nice pencil sharpener does a similarly good job of cleaning up the ends.

I picked up a 3 pack of these on amazon for like 5 bucks, still using first one

These are the best way to do it. Im fortunate to "find" them at work

Err on the side of longer. You can always cut more off, but you can't add it back.

An anvil pruner works extremely well also. They are garden shears but only have one blade and the other side is either a solid plastic or metal block. I stole my wife’s Fiskar trimmers years ago and that’s all I use. No pinching and super clean cuts with macro

This!

I use a razor knife that I bought from Home Depot. I cut it in the kitchen on a cutting board that I put flush against the edge of the counter. I do this so that the blade can push through the line completely without the frame interfering with the cut. A knife with a straight frame is best.



Also, I don’t angle down on the knife while cutting… I align the blade perpendicular to the macro line so that its straight up and down for a flush cut, then I use one hand to steady the knife and I use the other to press the blade through the line.

All that said, that fuel line cutter looks like the way to go. I didn’t know those existed until I read this thread.

I use a pipe and tube cutter that I found laying around. It took some practice to get them straight but it’s a clean cut. The scissor type.

I use a cigar cutter and aim for slightly long. Works pretty well but that fuel line cutter posted above looks like it'd work better.

After cutting it I take the sharp edge off the line so wen it’s installed it don’t cut the sealing oring inside the fitting.

Nail file works really well

I use a cheap old pencil sharpener to bevel the end and hit it with a little emery cloth to clean it up.

Many 010 orings were sacrificed so I could obtain the knowledge Chuck has given for free.

I use a No.11 Xacto knife and a small modeling square to make sure the cut is good and mostly square-ish. A light sanding to clean off and burrs or weird lips from the cut and it's good to go. I usually cut the line a little long, but I have one gun where I need to get the length just right....so I measure the distance the fitting's collar extends out and deduct that from the length I need.

I have a chest full of architectural drafting and model making tools, so I use what's on hand and what my hands know best.

I use a PVC pipe cutter to trim my macroline. It's a tool I have on my pegboard anyway and it provides a clean 90 degree cut.

Cheap coax cable strippers like these work great, unless you're trying to cut off just a really small amount. Like others have said, you need to round the edges after you cut it.
