I am trying to collect material and ideas in order to make a mini backhoe.
I may never make one, but I am proceeding on the grounds that I will.
Before starting in on how I should just buy a real backhoe, let me say I do
not need a real backhoe. I can really get by with just using a shovel. B
ut a mini backhoe that would be say 3 times as fast as just using a shovel
appeals to me.
I have thought about building a tiny mini backhoe, but the cost would be ne
arly the same as a some what bigger machine. The hydraulic cylinders and h
ydraulic valves are the major expense and they would not be significantly l
ess for a tiny backhoe.
I purchased the plan that are on Ebay for $13.99 and are not real happy wit
h them. Most of the drawings are three dimensional showing all the hidden
lines. And most dimensions are in the text. And the pages all have the s
ame title block. But I did not pay a lot so can not expect a lot.
I am hoping to collect most of the material ( not including hydraulics ) fr
om the local scrap yard. I am intending to put the engine, hydraulic pump,
filter and tank as a unit with quick disconnects. So I can remove that p
art and connect it to a log splitter or what ever. And hope to find a boat
trailer at the scrap yard to supply the wheels. I have already bought s
ome 3/16 rectangular 4 by 3 inch tubing for the booms and chassis. All in p
ieces only 4 feet long, but I have a welder. I also have some cut offs of
1 inch rod and some 1" bronze bushings.
So what I would like is comments. Especially from anyone that has built a
mini backhoe. Good sources for hydraulic cylinders and valves would be ni
ce. The Surplus Center is already bookmarked. Things to avoid would be ni
Oh yes, I am thinking about using my feet to swivel the boom instead of of
using a hydraulic cylinder. It seems like that might be okay to do. Maybe
have a plan on how to add power to swivel the boom if using my feet is too
much work. Or maybe figure out a way to use car clutch and brake parts to
swivel the boom. I am sure there will be comments on that idea.
