Nice to see you're still with us. Why did you elect to use a internal gear? What was that gear used on?

Re: Page 631 Walking Dragline
 

Hi Steve,

I'm always with you :). Thx for careing. I was doing some other modelling stuff and was trying to get this internal gear ring.

I'm still thinking about of building a rotary passage for power supply so I decided to use an internal gear rim.

I found it on the TV. It was a report about inventions. Someone was showing a rehab buggy for disabled persons with a connectible electric drive. This gear ring is screwed to the wheels and the pinion is spuring in.
I managed to find the inventor of this system and to purchase one of these internal gears from him.

Re: Page 631 Walking Dragline
 

where did you manage to find that?

Re: Page 631 Walking Dragline
 

I find it by searching the internet. Great invention. Isn't it?

Re: Page 631 Walking Dragline
 

I was thinking about how to reduce the weight of the bucket. Today I had an idea of some weight tuning so I made alot of sparks and cut some sections out of it. I will plate the new holes with much lighter aluminium sheets.

Hi lorenzo-I see you are working on the page again. Why do you want a light -weight bucket? I found the heavier the bucket got the better it dug. I actually added weight to my dragline bucket.

Re: Page 631 Walking Dragline
 

Hi Tom,

yes I'm doing a little on it. The bucket was to heavy. But I think it will still dig good.
I also had a mast collapse so the boom went down. The mast and one of the boom parts broke so I have to redo it. The mast this time in metal. I think the boom is strong enough so I will let it made of styrene for the first. We'll see.

Re: Page 631 Walking Dragline
 

This is how it looks now. I shut the openings with aluminium sheets.

Re: Page 631 Walking Dragline
 

Now you need holes so water will drain.

Re: Page 631 Walking Dragline
 

Yes, but only when I'll dig for gravel and similar under water.

Re: Page 631 Walking Dragline
 

You didn't consider plastic sheet to make the bucket lighter yet?

So how many cubic meter did you move before the mast/boom broke?

Re: Page 631 Walking Dragline
 

Hehe, good questions ;).
The plastic sheet isn't wear proof so that's why I choose alu.
Not a single one did I dig with it ;). I hope I will , some day :D.

Re: Page 631 Walking Dragline
 

oh i didnt know your mast broke!! glad to see you are still alive Lorenzo!

Re: Page 631 Walking Dragline

Re: Page 631 Walking Dragline
 

Lorenzo-your bucket is looking good! Sorry to hear about your mast failure.:( Do you have a lot of work to do to repair the boom?

Re: Page 631 Walking Dragline
 

Thank you Tom :).

One boom section broke into 2 pieces. I think it's relatively easy to repair. The lower section of the mast is completely destroyed.
The mast was lighter (smaler) than the boom. The failure started on that location where the hoist rope passes through the mast. There is a big diamond shaped hole.

Re: Page 631 Walking Dragline
 

It looks like a new bucket was delivered ;).

Re: Page 631 Walking Dragline
 

I've made a new spreaderbar (the old one had nearly 500gr) and changed the chains so the drag chains are longer now. Steve, what do you think, is it ok now?
I also weighted the bucket. It's 2,3Kg now. I haven't weight it before but I was told it has 4Kg. So, I would say alot of saving :).
