A news story to make Gunner's day....

QUESTION:

What would an approximate cost be to make a standalone backhoe? I see plans/kits like the Ground Hawg, Caddigger, and Trencherman with $3k pricing. Is it hard to find the proper type and size of steel plate, pipe, bushings, etc. for something like this? The plans (usually under $200) seem like a good way to save a lot of time matching parts and such.

ANSWER:

Finding the steel isn't a problem. Affording the hydraulics and power source is. A standalone backhoe will have at least 5 cylinders
(maybe 7 if you go for hydraulic outriggers) and associated control valves, hoses, a pump, engine, etc. Even from a salvage yard, that's going to be the bulk of the cost of the project.

Look at the package prices offered by Caddigger's supplier. The bulk of the cost is not in the (nicely) pre-cut steel pieces. Even if you scrounge the steel locally and cut it yourself, you'll only save a fraction of the cost, and you still have to come up with all the hydraulic bits.

I'm currently building the CadTrac, and I bought the metal kit primarily as a convenience to speed up construction. I wouldn't save enough by hunting up the steel and cutting it to size myself to make a dint in the total cost of the project. But the time it is saving me is major.

Their prices for the hydraulic bits aren't out of line for new parts either, and they're the parts specified in the plans. This also makes things simpler, though it is the area where you'd save the most money if you could scrounge them yourself from a salvage yard.

IMHO the prices quoted in the plan sets are highly optimistic. They're dependent on using scrounged hydraulics, motor, and scrapyard steel. Your cost will probably be higher. I know I'm certainly spending more to build the CadTrac than the plans say, and I'm buying the parts from their recommended supplier. OTOH, buying the kit certainly makes the project an easier one.
