Re: Another Tigercat...
 

Reg, Good looking build !! Its operates so smooth,will be cool to see it with the hydraulics and a sound generator. Congrats to you. Fred

Re: Another Tigercat...
 

Thanks guys. I just wanna get it done! I just took a break from the shop and it's sunny out now so I guess I should be putting up xmas lights:D..."but" I'm almost finished the hydraulic valve so I suppose I have to make a choice. I think this is where I have to do the right thing versus the "me me me" thing...Hows that go? Happy wife, happy life? But hey I'm not getting married til next year so:p...


Greg... I have to finish this first BUT!.... I have been taking pictures, collecting facts and measurements for off-highway KW's for about a year... I also have a stack of Milspec 2.2 tires thats about 2 feet tall and no way to move my equipment to the worksite....

Re: Another Tigercat...
 

Mighty fine machine work!

Re: Another Tigercat...
 

very nice work !!!!

Re: Another Tigercat...
 

Looking good, im impressed by you guys who can make your own hydraulics! Cred to you!

Re: Another Tigercat...
 

Man that set of spools are awesome. I though you said that you hadn't changed the mill over to CNC. Looks like a lot of work when into making them. Any tips you'd like to share
Rob

Re: Another Tigercat...
 

Did you made these with a manual mill? They look very good.

Did you knew how to machine before you bought that bf30 or not?

I just got myself bf20l and my first parts look good but their precision is shi....

Re: Another Tigercat...
 

Thanks a lot guys, I just hope it works:o! It is a bit of "f"ing around but it's really not that bad with a DRO on the mill. I used the plugs out of the valve I had made months ago and just made a new body and servo mounts so that spead up the process. I also "clamped" the servos in place rather than drilling and threading each mount. I thought it was much easier to machine two holders and only have to thread two holes verses 16. It also makes assembly go much faster. I trimmed a little more of the 'fat' off of it this morning before work and drilled and tapped the last four holes so now I just need to put it back together and push some oil through it!

Oh... Madda, Congrats on the new mill! I have no prior knowledge or training in machining, just a fair understanding of how things should work. My father inlaw is a tool and die maker by trade but I didn't ask for his help on this. I wanted to do it myself pass or fail! Hopefully it's a pass!lol I guess I will know soon!

Reg

Re: Another Tigercat...
 

Cool machine. That piece of work in your hand is pure art! Dan

Re: Another Tigercat...
 

Oh you're using DRO, that should make working a lot easier and precise? How did you make these larger holes, with a rotary table or boring head?


Keep up the good work and post pictures of machining setups when you are doing something, I would really like to see!

Re: Another Tigercat...
 

Nice machine work :cool: Have you made allowance for o-rings between the two main plates?

Re: Another Tigercat...
 

Had the day off because of the weather so I spent a little time mounting the hydraulics valves and such.

Re: Another Tigercat...
 

Nice work ! and the machine work to make hydro's is awsome wish i could do that sort of thing just not that close to tolerances yet lol

Re: Another Tigercat...
 

That's a cute Lil' pump!

Re: Another Tigercat...
 

Reg you just keep uping the BAR ! WOW You are very creative, keep the photo's coming...

Re: Another Tigercat...
 

Well since the 850 is nearly finished and there is a show in a month, I thought I should get the 630D back on the bench and see what I could get done. I had stolen the ESC to get the 850 going so a new one was installed here today along with finishing the wiring on the motors. I also mounted an on off switch while I was doing the wiring...Time to get back into the hydros and see if it can do more than drive around!

Re: Another Tigercat...
 

Reg, it's been a long time since you started this build, and maybe I missed it, so I hope you don't mind me asking - where did your tires come from?

Re: Another Tigercat...
 

Yeah I kind of got burnt out on this build and lost interest. The tires are from a New Bright Raminator truck. I just happened to ask the local hobby shop to keep an eye out for tires with chevron type tread and someone came in the next week with a Raminator they wanted to trade. My friend at the shop scooped the tires and tossed the rest. I paid $20 for them and they are perfect size for 1/10 scale. I've been looking for another set ever since with no luck.

Re: Another Tigercat...
 

I managed to put this together today. My father in-law made this pump up for me back when I started the EC300 but I ended up buying a Jung for that instead so I thought I would give it a shot in the Tigercat. It is made up of some "secret" gears and a CNC'd aluminum case. The drive is the original out of my excavator....http://youtu.be/Zc13A6xJLKE

Thanks for looking!

Re: Another Tigercat...
 

A couple pictures of the pump mocked up in position. I won't hook up any hoses until I make all the cylinders.

Re: Another Tigercat...
 

That's some serious pressure.

With everything you have now Reg, I belove you should be nominated for "Fleet of the month"!

Ben

Re: Another Tigercat...
 

Haha I think everyone on here has a fleet! That's the way it should be...

Re: Another Tigercat...
 

I still have a lot to do on this detail wise but at least it has some badging now.

Re: Another Tigercat...
 

Looks nice and tidy under the hood and cab! Glad to see you're back at this one. Think you'll go through and add some more details to it? Bring it up to par with the Kenworth? The Tigercat doesn't need a lot. Just little things maybe. Working lights, windshield wipers, cab window protection....ect.

Re: Another Tigercat...
 

It will get a little more detail but will never match the KW. I plan on adding some screen to the side windows and some cylinders to operate the hydraulics:rolleyes: but that's it. This is one of those projects that fizzled out and now I will just be happy enough to get the hydros working and move on.

Re: Another Tigercat...
 

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

Re: Another Tigercat...
 

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....

Reg

Re: Another Tigercat...
 

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:rolleyes: One cylinder in the grapple has a leaky O ring and the valve for the blade is out of whack. This was my first attempt at soldering anything like this so I was pretty relieved when none of the joints leaked. At least not yet...

Re: Another Tigercat...
 

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.

Re: Another Tigercat...
 

Looking sweet . Reg

Re: Another Tigercat...
 

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.

Re: Another Tigercat...
 

That looks great all around Reg. :cool:

Where did you source those right angle hose fittings on the cyls from? Are they metric or SAE?

Re: Another Tigercat...
 

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

Re: Another Tigercat...
 

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

Re: Another Tigercat...
 

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...
