Where did you get the excavator?

It's scratch built.

Ari got my thinking about doing some welding so I started on these this afternoon. I decided that I wanted a bigger digging bucket and a clean up bucket. I was trying to film a video of it playing in the shop but a servo on the valve block fried so now I have to replace that before I can. Anyway enough talk.....

Reg, you make it look to easy!

[Hemi1966]

Nice work Reg, it's easy when you know what you are doing
What's the material thickness?
Was that upper inside weld hard to do?
Can you take a picture of your torch. I'm thinking of purchasing a smaller air cooled torch, the one that came with the machine is water cooled and quite large.

[RCP57]

I wouldn't really say that I know what I'm doing. This material is .100 thick so it is much easier to weld than the .063 I normally work with. The weld inside was a tricky one to do once both sides were in place. I use 150amp air cooled torch and for this I also used the short back cap which makes it much easier to fit into tight spaces. I will take a picture of it tomorrow when I make the other bucket.

The gear switch is two position switch, which is why said the "on" side set to 20 - 30%. If you want slower speeds with stick movement, turn your mix switch off (upper right corner of my radio).

I have my 850 on a DX18 now, but even when on the DX8 I had the pump on a 3pos switch & never used the 3rd pos anyway for highest speed, the mix would take care of that.

And I set my throttle ch (boom lift) to always go full speed with/without mix within the programming b/c I need full power & flow to lift with any sort of speed... can't remember off the top of my head how I did that... but otherwise dig loose material with the mix off too conserve battery run time.

Thanks Joe. I started to change things a bit this morning but I decided to leave it for another day. I did manage to try out the new digging bucket though. This pump motor set up makes such a horrible vibration at medium speeds. It really drives me crazy. I'm using a love joy coupling but I think I may make a solid sleeve to try. http://www.youtube.com/watch?v=lI3tP8vGCSQ http://www.youtube.com/watch?v=W-F53RRfqUA

I got a start on the clean up bucket today but didn't get a chance to finish it...







Here's a picture of my 150amp torch. I normally use a #4 cup and change the tungsten to match the amperage as required.

Thanks Reg
What tungsten do you use with aluminium ?

Uh..yep...Haha I forget...I use pure tungsten but there is another one too and I forget what its called. I'll try to figure it out.

I finished up the clean up bucket tonight. Pretty basic buckets but they should do the trick!

Those new buckets look great !!!

Do you have any more pics of the slip ring you made??? (need some ideas for my shovel)

I left one pile of dirt in the yard from my little S10 dump so that i could spread some of it out with the RC's. The weather finally turned really nice again yesterday so in the evening when I was tired of working in the shop I got the Volvo and the Euclid out for an hour or more of playtime. I haven't ran the excavator for quite a bit so i was definitely out of practice but at least everything worked!
