Was watching this build on the Garden and have been constantly amazed by what you have made. Being a machinist by trade, lets me know how much time you have invested in this build. Hopefully, I will see this outstanding machine built and painted digging in some dirt in the near future.

Since I don't have anything new to add I'll be posting some old build photos for everybody's entertainment. Here's a shot of the tub removed from the rotating frame showing the rotary slip ring that transfers the power up to the machinery deck. Notice the 135# marking. That was the weight of the rotating frame less walking cams.

Here's another old picture of the revolving frame....

This one should have been in the earlier post on the swing gear box that shows me fitting the box for proper gear alignment on the deck.

Nice work steve-in pics 1 & 2 I see holes tapped on the main rails between the swing gear and the slip ring. Just curious, what are these holes for?

Ah, that was a huge mistake! I originally was going to make collector rings like the real machine only 14 circuits. I bought a $45 piece of Static dissipating UHMW plastic to machine out then press copper rings in each. After I spent a whole day machining them I was reading that the material was a good insulator only to find that was a typo in the McMaster Carr book. Static Dissipating CONDUCTS electricity! The salesman said I could send the mtl back but I told him I already cut it up. So I scrapped the idea and started buying rotary slip rings that came up on Ebay and I bought several to try. Now I know how much current the machine uses I may be able to put a slip ring in with more conductors. I have one the same size and make but 24 wires. With this type I could hard wire the whole machine and forget about using a radio to control it.

Thanks steve-I really like that slip ring you used. The one I used in my shovel had such small wires I really struggled with it. Also I needed more wires.

Hey Steve, you being a fine machinist, it sure would be cool if you could build the hydraulic pumps we use in this hobby. The kind off work you produce it would be an easy build. And it would keep the money in the good ol USA.

This model is just amazing... The hoist drum/shaft assy looks just like the ones that have come through our repairs shops over the years. Showed the picture to one of our service techs and he was hard-pressed to believe it was a 1/16 model! Just a marvel of machine work.

Here are some photos of the walking machinery. I can't seen to find more. I wonder if that roll of film is still in my old camera that quit before I used digital.

Mock up of the upper and lower pices


Rough Milling the kidney shape on the matching half's




Final finish and rounding over the track


Profiling the T shaped pieces that that cam pushes against





More milling and drilling

Matching the square drive on walking shaft for a perfect press fit

Milling the mount on the shoe


Milling the taper and bull nose on the bottom of walking unit


2 almost completed walking units

Good God you've got a lot of time invested in this, and it shows. Awesome work on the machining.
I've never heard of such a machine until I saw you on Scale4x4 and had to a search to see what it was.
I can't wait to see a vid of yours in action.

What CAD program do you use?
I was lucky to get digital readout on my milling machine but how funny to have a CNC.
Guess that out of budget for modelling purpose only.

Very impressing model, do you count hours put into it?
