Tractor backhoe - homemade

[Renze]

I know that problem... its impossible to use a linear cylinder to get a 180 degree movement without one cylinder getting over the dead point and working against the other... so you have to make with what you CAN get..

P.S. did you make your own hydraulic cylinders, or just adapt a do it yourself cylinder kit with the trunnion mount ?

I got a 2 mm difference between the swing circles and that only heappens at a small portion of the swing, at about 25 degrees but I believe it will work. I made cylinders out of 2 old ones by cutting them in half and making these middle mount rings

BFreaky;

What is the word cut from steel? (Behind right swing cylinder; as you look at it sitting in operators seat)

Thanks

The word is "prototype" . That's also my drawning.
It's the first machine, so it has to have some kind of mark on it. I will put some more, but they are not cut yet

Ok thx

Zoomed in to try and read the word but could not really make it out.

BGood.

Nice job BFREAKY....I'm sure your care and attention will work perfectly for a long time (and to your specific needs) as it is custom made to fit a custom-quality individual. If ever you decide to try this particular project again, I truly hope you will try to fabricate EVERY part (in a more simple manner) just to say that you made it MOSTLY from what you were able to do within the limitations of your tools/machinery and supplies/material. If possible, and if ever a more simple design would interest you in the challenge of doing it with less outsourcing, I truly hope the steps are video archived.

As an illustrator and "tinkerer", I'm glad I happened upon this thread and am exytremely anxious to see the finished product (in use). A video would be GRAND.
