Home made Backhoe

[Renze]

I've learned welding with a small stick welder when i was 10: Later my brother bought an industrial 380V MIG welder. Then at engineering school when i was 16 we had to learn torch welding. Later i also used TIG welders.

Iｴve used all methods in practice, so i should know what i'm talking about:
My brother sometimes asks me to weld, because my welds seem to stick:
I keep telling him that its the preparation that causes 2/3 of the success of the weld. Grind rust, zinc and paint off the welding surfaces, and cut a slot or keep an opening of half the material thickness, before welding.

A stick welder makes up for a lack of preparation, but it doesnt make any better or stronger welds if the welds are properly preparated. I only use the old buzz box when i can bend the rod into a position where i cant get with the MIG torch.

Thank you, I've welded with many different systems too.

Nice looking backhow! I'd like to see it in action. Very good job.

OK can we get back to the main topic of this thread, backhoe? Where did you buy the plan? I think I like this plan better than the JP Engineering backhoe plan..

Do I need to have an aux hydraulic system on my tractor for this backhoe to work or do I hook up to the PTO drive? I am hoping for a hydraulic system hook-up but when you said that this backhoe of your is too strong for 3-points, what did you mean? Can you clarify?

Thanks!

By the way, it looks so great and liked your work regardless of what many opinions about how it is welded..

An Excellent Idea.

I am also interested in the 3-point question.
Unfortunately it looks as if Vicashoe the starter of this thread never came back here!

Hi All,
The Vicashoe is a modified 708 model from CadPlans Corporation - Where you can find designs, tips and order information to build your own backhoes, diggers and MORE!
There are a couple of other plan suppliers
Backhoe Plans: Build a backhoe, these plans show how. CDP backhoe > manufacturer of backhoes & thumb kits
Backhoe, Backhoe plans, Build a Backhoe, CAD plans - welcome to Backhoeplans.com

cdp probably have best digging geometry BUT use a rare cyl size mainly available from Princess Auto, Canada. Sells basic plan cheaper under name oldriga on ebay sometimes.

Cadplans easier to build & use more commonly available cyl size (closed length
pin centre to pin centre) available Northerntool etc, so costs lower, wish I had gone cadplans as in uk - might go half share in cost to get a copy. Have found good sources of valve block, pumps, motors, uk but not yet cyls (rams)
Have a friend who has dug up old expired patents re. 180 swing & cracked them matematically to use std cyls.
New to tractor by net, just joined to help out with plan source, will check out if site allows email or PMs between members, if so I am happy to help

I went to a backhoe thread and a welding thread broke out.



Politics, Religion and Welding. Three subjects to avoid at ALL costs.

Richard61,
Thanks for posting those links, and welcome to TBN.

This cracks me up when I hear it. Your family car along with every piece of modern machinery including all the new tractors and heavy machinery coming out today are welded with guess what.... CNC MIG.

I will have to repeat this hoe was stick welded with 7018 rods not MIG welded. Sorry it took so long to reply

 

[vicashoe]

Excellent hoe, after all it's a vicashoe! About how long does it take you to build one like that? The cylinders, are they 2.25" ID with a 1-3/8" rod? After enlarging the photo 400% I was trying to figure out where you rest your feet? I didn't see a foot rest or floor plate. Another question I have is how did you bend the curve in the plate to form the bucket?

Very impressive......

Larry

2 1/2" x 14 x1 1/2" feet are supposed to have a plate below the valve but I have yet to put it on. Bend in bucket is arm strong with a come along

 

[vicashoe]

I believe he cut out a thin notch and welded it back up. Is that right? That is what I did to mine.

That is exactly what I did but I am thinking 10 degrees instead of 7

 

[vicashoe]

Are one or two rams used on the swing. What is the swing angle?

one ram 14" and 135 degrees

 

[vicashoe]

how much did it cost for the backoe material ??

everything cost around $1200 scrounging ebay and all the discount places

Iplayfarmer ,

Then, let me ask you this, Do you have what you think is a good welder for the material you are welding? Do you think a qualified Mig welder could do some outstanding welding using your machine, staying within the boundaries of your machine? If that is true, then you should be able to achieve the same results. I believe that the ability to succeed, is in every one of us, and the ability to achieve a particular goal is up to the individual and the amount of training he is willing to go through. Most of us do not have the training that we would like to have, for whatever reason, be it money, time, working to many jobs, night courses, etc. I believe that you, me, just about anybody can build just about anything you want with enough training and practice.

I would love to have a good shop, with a computer in side room, and be able to draw something, cut out the pattern, and weld it up, and then look at what you have done, and sit back, and say D*m, I'm good.

I scaled the drawings to a 1/8" piece of hard board, cut it out with a scroll saw for a pattern then clamped it to the steel I wanted to cut. Cut it with a plasma cutter. No computer cutter NOR A MIG WELDER here.

I incorporated a Prince pump to the hoe and attached it to the PTO shaft. Too strong as far as digging pulled the top link apart on a dig once thus the need for a subframe. The plans are from CadPlans Corporation - Where you can find designs, tips and order information to build your own backhoes, diggers and MORE! I did make alterations to it like a deeper dig by cutting and angling the boom to 7 degrees also the hydraulic outriggers
