Good morning,

today the first boom pictures. I choose the short one for the model. It measures from main bolt mounting to stick bolt mounting 780mm.
It's not only a foursided housing, there is some structure inside to stiffen the whole thing. As you can see, the drum inside is made with two halfs whitch were welded together. The outer diameter is 74mm.

some more...

it came together very well, all parts got mounting noses and holes like a puzzle again for easier setup. Then the noses were welded at the outside to avoid warpage. Michael did an amazing job on the mill and fabricated the massive steelpart. It will take the two stick cylinders.
The stickside of the boom were doubled up with some lasercut parts and after this I wrapped a belt strap around the sandwiched parts.

Wow Markus....really like this build !! Great ideas, excellant workmanship and a larger 1/10 scale...looking forward to seeing more..well done!!

What is the size of the bucket??

thank you guys for your comments. I'm looking forward to show the stick today.

About the bucket, well, it fits to the machine ;-) it is a massive HD Bucket for digging rocks. Sure I'll need some other ones for digging in sod and topsoil, the Rock bucket will be rather ineffective for this. For easy changing there will be a hydraulics operated quick coupler. The bucket needs some more welding, but I ran out of gas for the tig.

greets Markus

Hi guys,

here some stick work. I made two of them, one fits to Michaels R9100. The lathe bcame more and more useful, here I did the slope on the frontend parts of the stick. It comes together very well, but due to double cylinder action I did a little line boring and reaming on my lathe.

Thank you, Ed. But I've to go a long way to the end, remember, this project started in September 2011. But I think it's going down the hill!

We come closer to the bucket but first I'll show up with the OilQuick120 quick coupler. Fortunately I was supported from the manufacterer with a drawing and some really good pictures. For this I had to made some really small double-acting cylinders. First tests with compressed air were successful.
Half of the parts were lasercut parts, the others were milled/ premachined by Michael. First I drilled the 1mm holes up to 1.3mm for tapping with 1.6mm (I'm proud to tap 48 holes without breaking that little sucker). Later there will be screwed covers whitch will hold the bolts in place.
The cylinders are simple brass tubes with the head soldered in place. Then I did some internal lathe work for the o-rings on the front and for the lockring on the backside. Really simple made.

After this a lot of tig-welding and some sandblasting. The last picture shows how the locking bolts locks the bucket.

Hi folks,

@Avel: thanks for your comment!

@all: I know you're all waiting for bucket-pictures. Well, here they are, but it´s not finished yet. There´s a little more welding to do, but I think it´s recognizable.
The teeth are sandwich-made using two halfs of lasercut sheetmetal, each 10mm thick. Could be the canines of a grizzly The knife is 12mm and needs some milling first (like the teeth).

and the next ones. The bucket without the knife is for my college Michael, he's got some different teeth (toothcarrier and crown). Anyway, he did a great milling work.

It's just incredible that you can fit a gallon jug into the bucket... that model is gonna be just massive! I can't wait to see the pictures of you standing next to the finished model!

I thought your colleague Michael was building a front shovel?

thanks for your comments!

it's even more than a gallon! Today I was a little scared by myself , I put the stick on the bucket. The phone right next to it is a usual size.

No, Michael builds a backhoe attached R9100. Here two pictures showing the stainless steel laser-sintered toothcrown and the knife. Markus

Your 1st pic with the stick & bucket, drop that assembly on a scale, let's see what it weighs... then how about a pic with you standing beside it for a size reference?
