I wondered for years if getting a crimping machine was worth the effort and expense. Then the Volvo started popping pilot lines this spring. Local Parker store price was crazy for these. Even when ordered onlne the cost with shipping was pretty hefty and I had to wait for them to get here.
I suppose if the machine was on a paying job at $350 an hour a $100 hose would be cheap, but when it really is a farm tool things are a little different. So I looked for a machine at auctions, craigslist etc.
Finally found one a few weeks ago at a great price and came with boxes of fittings. It was a local craigslist deal.
It is great. Cut my hose price by half or more and I get them right away and to exact size.
If you do this there are a few things to learn. First, there are 2 kinds of machines - postive stop and adjustable. Positve stop is easy to use as there is no adjust but you are limited to specific hose and fittings. Adjustable machines can do any fittings but you must be willing to learn crimp specs, measure and adjust as needed. All come in various sizes (tonnage) to crimp certain fittings.
You will need to stock hose, fittings, adapters etc. but the reality is most things run on 3/8, 1/2 or 3/4 hose. A decent selection of 100r1 and 100r2 hose will cover a lot of things. Most smaller machines will do these. Medium machines can do up to 1" 4-wire. When you get to 4 and 6 wire for really high pressure things you can stock jsut a bit or buy them as you need assembled.
The first thing I would look at is what hoses you would want to make. Then look at cost. There is a lot to learn about safely making good hoses but if you are willing to put in the effort ypu can save a ton of money and downtime.
