I started my backhoe Root Ripper.

[the old grind]

... Does anyone know where I can get some bucket pins for my quick connect, they need to be 30 mm or 1 3/16.
the factor pin is 127mm or 5" so it would need to be 5.5" with pin on the end. They do not need to be greasable because they are on on the QC and don not move.

Go to a local steel supplier and buy 'stress-proof' steel round in choice of diameter and 1 pc total length for the pins you'll make (u cut to length w/hacksaw or bandsaw or their $2-3/cut?). Material has a tough, smooth, accurately-sized surface and finish. That said, be warned that you just can NOT weld 'keepers' on ends, but you design to drill/tap for those with even your DeWalt 18v cordless.

It's an easy-working ('free-maching' in the trade) steel alloy which is why it won't weld with any rod or process yet known. Otherwise "stress proof" is a well known/used bottom-price, top-performing, DIY-friendly material for pins that one can work with almost as easily as aluminum or brass. The first pin I made for the backhoe sold me on it to use for all since. t o g

For my pins I get 25mm round bar from McMaster Carr and cut to length. They have lots of different kinds, I get the cheapest. The local steel supplier has cold finished round bar in inch sizes, which is less expensive than MC, but they do not have mm sizes.

Thanks for the pin info!

Here are a couple more pictures of my new QC.







I need to clean up my welding/steel and put a coat of paint on it the root ripper.
Once I have some pins, I can try it out the QC and the root ripper.
Next up is making my 16 bucket but that is for another day.

Nice job on the coupler!

Thanks.
There was a lot of work that went into it before I could have it tacked welded together and test it with a bucket to make sure it would work well.
Once I knew it would work, I was all set.

It is loosely based off pictures of the Bxpanded QC the BX backhoe is similar the my GC 1710

On the topic of getting the most from your hand held bandsaw. I made a table for my DeWalt about 4 years ago. It is very accurate and versatile. I use it weekly. I can't say enough good things about that DeWalt saw. It is flawless after literally years of steady use.

In the photos I am making parts for my new backhoe thumb, 3 pieces of 3/8 x 5 in flat bar, 7-3/32" long. And 2 pieces of tube for temporary spacers, also 7-3/32". Easy peasey.

Wow! Nice bandsaw table.

I'll second using 1144 stressproof for pins, been using it for years and works great. You can actually weld it. I wouldn't trust the weld for heavy structural applications but have welded retainers to the end of pins and they hold up just fine (tig welded).

If you can get it in TGP (turned, ground, polished) for close the same price go for it, I've had some 1144 not be as round as I like for pins.

Thanks so much for the advice. I just picked up 3 foot 1144 TGP $39 OTD. My local place only caries TGP but that will work for me.
I will have to cut it and drill it for pins.
This is enough where I can leave one pin in each backhoe attachment.

I made two pins so far. These pins are just a tiny bit bigger. They fit but I need to adjust my quick connector a little.
I think I will chamfer the outside edges like the factory ones. I think that would help some.
