Nice work steve-you should think about becoming a machinist !! That should give you good traction now. The show sounds like fun! I hope you have someone to take lots of pictures and videos!

X2 since I can't be there

Adding some pictures of my machine to this thread I have elsewhere on the forum.

I clamped my camera on where the operator's cab will be to get an operators perspective.



I need to cut the excess links off the drag chains now that I have tried digging with them shorter than I originally had. I think now they are closer to the proper length per scale. I can also dig about 3'' closer to the fairlead now.

Like the operators perspective.

Thanks for posting them Steve.

Thanks for the link. I look for those all the time but haven't been on ebay for a couple days. I was up to camp this past weekend but we got sort a rained out. I have one of those in my collection too.

Time to get back building again on this. Not much time till the Cabin Fever Expo. I've been designing the wedges and other bucket rigging that I threw together last year. Everything served me well but it just wasn't "to scale". should have something to show soon. I still need to make a trip 295miles out East to the 1:1 machine to get more sizes on the exterior house and "A" Frame.

Here is a start on the "Crows Foot" this is where the drag chains,dump rope socket,and drag rope socket meet. I made it out of 4140HT steel so it wont wear out dragging in the dirt.





Stepping down with a 1/8'' ball mill to make the taper.

Very nice work Steve the more you do on it the better it gets, keep up the good work. Ed

Man, what an intricate piece! I'm coming over to hang out

Finally figured out an attack on the drag rope socket this weekend. Had to make it in two pieces then I'll Tig weld the halves together. Sorry for the ugly finish, I have lots of blending with the Dremel and Lots of deburring to do still on this one. I still need one more this size for the hoist and two smaller ones for the dump rope.

Simply amazing!

Here is the drag socket TIG welded together. Of course there is some grinding and filing to do. I had one heck of a time seeing what I'm welding! I even have a 2X magnifier in my helmet and was wearing my 2X cheaters

[rockNmayhem]

Steve that looks absolutely astonishing. Great welds for being so small and very clean looking socket. Can't wait to see what it looks like cleaned up.

More rope socket construction photos from last weekend. This time this is the hoist rope socket. I still need to radius the sides some.

Way beyond cool...

This weeks project is to design and machine the hitch links that the drag chains attach to.

Here is a shot from my ESCO salesman sample bucket showing what the completed parts will look like.


Left hand and right hand pieces started

That's incredible work! I wish I could TIG weld that good! And machine parts that well too!

I can't see what I'm doing!! I probably could have made smoother welds 10yrs ago when my eye sight was better The welds will get ground down anyway.
