Hi all -

I looked for a newsgroup about hydraulics but didn't find one... so here
we are...

We are in the process of repairing a truck mounted hydraulic crane (an
old power company rig that digs holes, sets poles and generally does
lots of stuff).

Yesterday I replaced two of the approximately 3,218 hydraulic hoses on
the rig and paid about $100 for them. Since there will be more hoses to
replace as we get into the project (and we also have a backhoe with
aging hoses that will need some attention in the future) we are
considering getting the tooling to do our own hoses.

The crimping machines seem godawful expensive - and there seem to be two
or three manufacturers (Parker, Weatherhead, Gates, etc.) with
apparently incompatible fittings and crimping dies...

Is tooling up for what we want to do reasonable for the amount of hoses
we will be making or is it more cost effective to run down to the auto
parts and have them made for us as needed?

Anybody do/done this and have any words of wisdom?

Thanks in advance

Carla

You didn't really say how many hoses you expect to make in the end.
If your project will be a lot initially and then only an occasional
hose, you could buy a crimping machine, possibly even used, make all
the hoses you need, then sell the crimper. After that, pay the $50 for
the occasional crimp job.
