Reg, I know it has been just about a year since you worked on this one, but I've been waiting to see how the valve would work and if any leaks developed when in use. Just finishing (Painting) the RH400, but the valves I build are to large for the L2350 loader I have started. Like you after awhile I get bored with a project and start a new one ,if the valve worked this would solve the room problem I foresee.
Thanks Earl |

Sorry Earl but this thing hasn't had much attention in a long time. It has been on the bench, looked at and put back on the shelf several times but no progress has been made. I would really like to see it operating but I just can't seem to muster the interest needed to build the cylinders and air cylinders are hard to find(expensive) in the strokes I need. I have all the necessary materials just not the determination....

Well it has been a long time since this thing has had any attention but for some reason I got a bee in my bonnet the last few days and threw it back on the bench. After about 3 days and over 30 hours in my shop this is what I have...
Completely one off hydraulics, pump, valves and cylinders(some of these parts were already made). They even work!...well kinda ![]() http://youtu.be/QpvGxaJk3G0 http://youtu.be/7ZONUWIWIeU ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() Thanks for looking! |

It's nothing fancy. Just silver solder. I don't need to run a huge amount of pressure on this one so it should hold up fine.

Nice, Reg. Really nice. I enjoyed the videos. Just a thought for the grapple. Maybe you could devise a spring assist to help the grapple jaws open and close evenly? Or maybe things will get better once your parts wear in a bit.

That looks great all around Reg.
![]() Where did you source those right angle hose fittings on the cyls from? Are they metric or SAE?

It looks very nice. Seems like the performance is up to standards as well

Thanks guys.
I was thinking the same thing Nate. The cylinders for the grapple have enough exposed rod that i could put a helper spring on there. I think I will wait and see how often it opens goofy before I change anything. The fittings are SAE(10-32x1/8" and 10-32x5/32") and sourced through a local Hydraulic shop in Victoria. They are meant to be used on truck air lines and so on. I use them on the Volvo too and have never had a failure so far at 32bar. Metric is available too but harder to get. They are a bit big for smaller cylinders like this but are about $4-6 each and often in stock at the local shop. If they don't have them they are typically an overnight item from Vancouver. A banjo style is available too and has a slightly lower profile. Reg |

I got a few of the kinks out on the skidder today(literally). It turned out that the issue with the blade was a kinked hose so I shortened it up and that solved the problem. The valve block was weeping a bit so I took it apart and put a thin strip of loctite around each rotor and buttoned it back up. No leaks there now. The grapple cylinder was binding mid stroke and causing it to leak. I made a bit of a relief near the swivel and now it only leaks once and a while. Once I did all this and finished the wiring, I decided to have a little playtime. I'm now running most of my models off of one radio so I need to remember to center all the switches between models! Oh well, hopefully I will get it all figured out one day...

Thank you very much guys. I still have some details and paint to add on the skidder but I must say that I am happy to see it fully functional. I think a smaller hydraulic pump would be a nice addition as I have the speed dialed down a lot on this one. I also need to invest in a better battery. The 5aH lead acid doesn't run for long before it dies and it's added weight really isn't necessary on this machine. I added foams to the tires yesterday and that seemed to stop the crumpling on the rears.
Does anyone have any experience using the complete pump setup from RC4WD? I think it is around $225 for the pump and motor but I have no idea how much oil it moves. I need a fair amount of volume for this, just not as much as I have now. ![]() Reg |

Glad to see you have your model working, as always a work of art. The hydraulic valve working with just minor leaks is what I've been waiting for, now its my turn to copy your build and build my own for the l2350 I have under way.
Thanks Earl |

Yes the valve seems to work OK with no leaks now that I used some loctite between the halves. I could have machined grooves for O rings around each valve and that would have been better but I was lazy.
Any chance you will be taking the ferry ride over to the island next weekend to attend the Atique truck show with us Earl? Lets see some pictures of your build! Reg |

Another great build!!! Watched the vids earlier today....NICE.....
You need better foam in the tires if you're going to always haul those big logs around...LOL...again nice job man well done!!! KP |

Thanks KP. It needs some work but I'm happy to finally see it fully functional. I put some foam in since the videos and there's no more flattened out tires now!lol

I have been waiting for some motors to be in stock at the Robot Shop for months. They are supplied by Servocity and I could have bought them there but for some reason their shipping to Canada is really expensive. Anyway, a while back I made an order from RS and they had 1 in stock. I need 2 motors but I thought 1 was better than none so I bought it to try. Here are the results of changing the motor....http://youtu.be/LtbxUR9raN0... I guess I will order another but I'm not sure how useful it will be. Maybe I should glue the rear tires first...
