Finally Building my Backhoe

[Iplayfarmer]

Iplayfarmer:

Thanks for those instructions. I will have to do it on paper as I have yet to get SketchUp working on here. Is there a formula I can use to calculate what length cylinder with what stroke I should be using? That, in large part is where my confusion lies.

I don't know of any. As a starting point, it seems to me that most cylinders have a stroke that it about 40% of the retracted length. I.e. a 10 inch cylinder has about a 4 inch stroke making for a 14 inch extended length. This is a rough figure.

Someone else hopefully knows of some kind of a calculator. Maybe they'll chime in.

thats why grinders were invented.

Absolutely!! I keep two of them handy, one of them with an aggressive wire wheel to polish up what the chipping hammer misses.

You could try using search as I'm pretty sure I saw a thread on it somewhere on one of the forums, or a simple thing I've seen is to weld a couple chains from the end of the stick to the inside of the bucket just behind the teeth . The chains should be long enough so that they are almost tight when the bucket is fully open.

That's an interesting idea. I have not seen it done that way, but it
would work.

I saw pix years ago of an articulating plate that fits inside the bkt, but
stayed put when the bkt rotated. That would only work with bkts of
a certain shape, however.

To avoid clogged bkts, I don't use anything less than 12" wide. Also, if
you drill a few holes in the bottom of the bkt, the suction will be broken
easily, which helps.

I'm pretty sure chains is the way I'll go. I had thought of a couple pieces of angle doing much the same as the plate you mentioned but the chains sound so much simpler. The holes in the bucket bottom might work if it was just muck we're talking about but this is Lake Agassiz / Red river bottom clay. I vow with my hand over my heart, there is nothing gooier!! Another thing I plan to do is taper the bucket a bit. The open part will be just a bit wider than the rear or bottom so that side cling should be less. Now if only we would have some dryer years all this would be moot!

I did a little work on the boom today. I've started a thread that I'm calling "It's time; either get started or.... Thanks again for all the great advice you've been giving me and I look forward to lots more to come!

Post us a link. Thanks.

Posting links is one of the many things I don't know how to do.:ashamed: Another example of too few functioning brain cells!

I've subscribed to it now so that I can see updates as they happen.

You might also check out Chad22's build as he's mounting his onto a garden tractor similar to what you are proposing. There are a lot of lessons to be learned in his thread.

Ok, that looks just like what Iplayfarmer did for me higher up on this page, thanks
