Looks great RW. I feel your pain with welding 1/8 aluminum. Just like you I can do it sometimes but as you said, a moment too long or a touch too much on the pedal and it's like snow in the summer.

Re: Great Dane excavating co.
 

Still amazing I would have used brass but I guess that's train thing background . You aluminum welders work out s stunning to see

Re: Great Dane excavating co.
 

the hand rails look good what you have done so far ..I am pretty ok at working with brass and my soldering is above average ..the other day while working on my ladders something didnt look square enough for me ..took the plyers and tried to tweek it a little ..ended up breaking the joints..not super strong but it will do..I purchased a square wave lincoln 200 last summer and still have yet to set it up..some good vids on youtube welding some small stuff..maybe some helpfull tips on there for you ..well i hope to be able to do somewhat ok behind a mask one day .maybe holloween . lol wishfull thinking

Re: Great Dane excavating co.
 

I don't know why I didn't go with brass, guess because I had alum on hand and some steel. But still need to get a couple more pieces of steel. The aluminum is tricky to bend, as I couldn't find any bend able stuff so 6061 rod. Have to heat it and then it's may still stress crack on some of the 90s. So that's why I'm also doing steel. A lot more forgiving in the bending and welding. Was having a hard time keeping parts in place even just to get a tack on them. A little bump or poke with the rod and they are moving. So I made this up to get square 90s and to hold things in place. As long as it last for a couple it will be fine. Just have to get a quick tack

Re: Great Dane excavating co.
 

What type of bender or method are you using to bend your material, I'd like to get something to use on brass just not sure what works best. Your railing looks great!

Re: Great Dane excavating co.
 

I was mostly using a 30" 3-in-1 brake shear roll bender. I know it's hard on the bar but I used one section on end for all my bending. Would square off blade vertically and horizontally to try and keep square. And a bit of tweaking in the ole bench vise while slipping a tube over the rod as to keep material bending at the bend and not length of rod.

Wow looks and run great can't wait to see it painted

Re: Great Dane excavating co.
 

Hard to appreciate its size just from pictures... maybe someday I see it person. :) :cool:

Looks like it gets around with plenty of power to spare.

What's the hyd pressure set at to dump the load?

Re: Great Dane excavating co.
 

Great job Cooper

Re: Great Dane excavating co.
 

Anytime you are south, and east,,, your always welcome joe,, power, yes plenty, she will go up more than 30 percent incline. I haven't tested fully loaded but for what she is designed for around a 10-15 percent grade that doesn't pose any problems. I may even change some of the gearing in the 4:1,4:1,3:1 tranny. May switch to three 3:1 plantary. Just off top of my head I think the total reduction is 144:1, I may drop it to 81:1 or 108:1. They are my options that can easily be done by just swiping carrier , planet and sun gears

I think the pressure is still around 100 psi, haven't messed with any of that yet. I did notice in the grass when fully loaded sometimes the steering cylinders would stall when vehicle was stopped. But hey it's never good to be trying to crank the wheels unless you are moving. So that really isn't any problem. And lifting is no problem even at that pressure!! Guess that big 3/4" boar really does pack more punch!!

Thanks mikem!!!

Re: Great Dane excavating co.
 

Well done ..steller build ..yellow with make it stand right out

Re: Great Dane excavating co.
 

When are you going to demonstrate it as a beer cooler?

Re: Great Dane excavating co.
 

Cooper-that is a big truck!! Like Joe said-it is hard to see the size from the pictures but I can see it is big and will haul a lot. Nice work!!

Re: Great Dane excavating co.
 

Well I've been trying to gather all my options and solutions for increasing the speed of dumping the bed. After a lot of numbers, ideas, evaluations,, I pretty much came to the conclusion of it is what it is!!! I could possibly get a different pump, as I have the lesser flow one from premacon. I think the 600mil/min. Could go with the 1200mil/min. Now that would theoretically cut my cycle times in half, and the bed should take 15seconds to go up. But with running two cylinders off one valve and having a internal boar of .75" and the I.d. Of fittings acting like road blocks the best solution is to get the higher flow pump and have each cylinder supplied from its own valve. And run 4or 6 mm hose to them. Rather expensive modification:). Guess this is good reason for most people having a "plan" or doing the calculations before they cut parts or purchase parts:)!!!! I don't like the idea of independent valves unless a equalizer line installed.
Do you guys think doubling mil/min flow from 600 to 1200 will noticeably improve cycle times? I keep going back to inner diameter of fittings and hose as major restrictions for rate of flow. I'm sure I'll find a home for a hydraulic pump if I purchased a new one, :)

Re: Great Dane excavating co.
 

I'm not sure what your fittings are like but the SAE fittings I use have the same internal bore for both 1/8 and 5/32 sizes. The excavator uses 5/32 hose and fittings but was restricted at every connection. I drilled out the fittings to match the inside diameter of the hose and the difference in speed was noticeable. I'm not saying it was an earth shattering change but it did help. Can't you swap the motor and spin the pump a bit quicker?

Re: Great Dane excavating co.
 

It's a haul truck not a race truck. Your lifting the
Heaviest load out anybody here. Leave well enough alone

Re: Great Dane excavating co.
 

What is the # on the Jung pump? What do you have the pressure set at?

Re: Great Dane excavating co.
 

I thought it dumped just fine . Maybe open your fitting ports like Reg said .

Re: Great Dane excavating co.
 

Awsome ....the fine detail makes these models stand out ...nice ..How is the tapping going so far ..I have been doing quite a bit of 0-80 latley and it seems almost easier then the 2-56 and 4-40 ..Broke 2 2-56 on this my scraper build and one 1-72 ..2 of them were because I dropped them ..lol
I have to found some pretty good deals on Ebay for taps but should start looking for some good drill bits..my local suppler is charging over $5 a piece for the smaller bits ..they are good bits tho ..
Nice work buddy

If I would have planned ahead,,,,,,,, I wouldn't have to make simple tools like this!! Had to make an extension for drill bit and tap for holes along bed rails. Hand drilled:(. Haven't broken any bits or taps for a long time but most of the small ines I've broken have been from dropping them also!!! The first ring of bolts on the wheels are just for show, drilled a little under and just pressed them in. Every time I think I'm close to paint I realize another detail that would look good, feels like never ending!!

http://i1357.photobucket.com/albums/...psedocea5e.jpg

Like this hitch, have to tear the back end out to get in mill for cutting/tapping. Then thinking about small things like supports for wire to lights ect,,,, but I've learned if I don't do it now I don't do it. Still have lights for excavator laying around that I keep saying I'll get to!,,,,,,

Re: Great Dane excavating co.
 

I have done that, after thinking a few hours how on earth to reach such a spot and it took only minutes to make a simple extension.

is it going to be yellow for cabin fever???

Hopefully be yellow within next few weeks. :)

Wow you got that together fast.

Re: Great Dane excavating co.
 

Got to McMaster.com for your drill bits. You can get cheap ones or get the better ones much cheaper than from anyone local.

Re: Great Dane excavating co.
 

Much better in quality too . I get mine in packs of 12 .

Re: Great Dane excavating co.
 

New gears arrived today, just in time for tear down for paint. Ihave 144:1 reduction and with these new gears I can change to 108:1 That might be a little closer to scale speed. Also can go to 81:1 (or 96:1) but I think that will drastically drop my torque and be too fast.

Re: Great Dane excavating co.
 

OK when did they change they're yellow again :confused: I notice 2 shades at Cat Monday but didn't think to ask .

Re: Great Dane excavating co.
 

I think they only have the two, the new yellow is more dark than the old. Probably been 10-12 years or more for the new paint.

Re: Great Dane excavating co.
 

One looks more mustardy
