Square cut to Radiator Hose

Today, Paul on s/v Solace shows us a masterful way to cleanly cut heavy hose:

Sometimes we need to cut radiator type hose with a nice square end. Some of you know how hard that can be with the hose unsupported and cut with a hacksaw. Here’s how we do it. BUT, don't do this if the hose has a metal spiral inside. Your saw blade won't like it.

Take the hose and find a suitable piece of dowel to insert into the hose. It helps to have a firm fit and if your piece of dowel is slightly over sized, use a belt sander to take the end of the dowel down to a slight taper until it fits snugly into the end.

From my pictures you can see two hoses; one fitting inside the other. It was important for me to not only get both hoses cut square at the ends, but to also have both hoses cut to the same length.

Once the dowel was placed in the end. A line was marked and we used a table saw to cut the hose. Be careful not to cut fingers! Leaving the dowel in place in the end of the hose, we turned it over and repeated the process at the other end.

If you don’t happen to have a table saw, here’s another technique you can use. Once your dowel is placed, take a square piece of paper, and roll it around the hose so that one edge comes around and lines up with the same edge as it is rolled over the hose. This is to ensure the proposed cut line is square to the hose. Slide to desired position and with the paper firm and edge lined up, scribe a pencil mark around the hose on the paper edge. Remove the paper, and now proceed with a hacksaw to cut the hose to the line; rotating the hose as the hacksaw cuts into the wooden dowel. This is a better technique if the hose has the metal spiral "spring" inside it. The hacksaw will cut through that OK.
