Beautiful work with the brown stuff, I love the way the knot works as an eye. Your repertoire of talent amazes me to no end

Thanks Chester - that is not a knot, that is the eye carved in to the wood. This is based on an old weathervane that is a bit stylized, I am copying its pattern.

Yesterday I got a coat of paint on the gears and guide wheels - the interior machinery is going to be all a steel color, which is how the real machine is (frame/floors/booms are black).

And got a start on making up the fixture blocks to hold the guide wheel bracket for silver soldering. Couple of blocks, notched in the corners to avoid soldering the fixture to the parts. They also came in handy for setting the angle on the parts to mill the ends to fit each other. Here, the angled end is at rough cut length:


Here is the end cut down and notched:

And the guide wheel bracket ready for silver soldering. The fixture has some NicroBraze on the mating surfaces to keep any rouge solder from sticking them to the parts. The same fixtures will be used for soldering up the smaller bracket, which holds a set of guide blocks.

After soldering, the ends of the top will be milled to match the angles, and the bottom rail will have the center cut out leaving just the 'feet' at the ends.

Chris, you do realize with painting all those gears that you are going to be in trouble with Don. I bet he was waiting to see if you polished them.  :Jester:   :NotWorthy: :praise2: to both Chris and Don. :old:  :DrinkPint:

Oh well!  I guess if he wants to travel up here to polish them I can strip the paint....   ::)

Got both of the guide wheel supports silver soldered up, pickled, and brushed clean this afternoon. The funny shaped bits at the left side are the soldering jigs.


Then trimmed the feet to length and trimmed off the top ends and the bottom center. Now they are ready for some JBWeld to fill the temporary holes from the soldering jig, and drilling the mount holes for the feet-to-floor screws and the axles for the wheels...

That's some mighty nice fabrication work there, Chris!

So, what are you using for your 'steel colored' paint?  It looks nice. But now that I've got paint on the brain, I guess I need to know what you're using  :embarassed:

Hi Kim,


I have recently started using DupliColor ceramic engine spray paint, goes on nice and thin, can take high heat but needs no baking. This is thier Cast Aluminum color, is a good match for the 303 stainless color. I have used their black for the frame and floors, also on the rc boats, holds up well.  It needs a couple thin coats, can be recoated in ten minutes. Nice stuff.

Chris, those guide wheels painted up look just like full size freshly sandblasted iron castings on a foundry floor. Great work (as usual!)

Today I got the slew chain brackets bolted to the floor, and was able to hook things up for a test. Turns out that I had to unhook the chains, and line up all the links without any twists, or it wanted to walk off the turntable edge. Makes sense, cuts down on wear as well. 

Here are a couple of photos, then a video of it in action:

Here is how the forward ends of the chain go around the end of the boom, and get drawn in by a pair of hooks. The hooks go through the boom, and a nut on the other side (the hardware kind, not me... well, me too) can tighten them up to tension the chain.

Whoa! Looks like a potential Elf 'n Safety issue there, even if he is wearing a hard hat ...  :slap:

We all ran out of superlatives long ago but some great work on those gears, and the control levers and, well, everything  :cheers:

Mike.

Thanks guys!


That elf is standing where the real boom operator would have, who would have had a normal cap or hat on, no hard hat!  Even the main operator stands inches from the spinning guide wheel, no guards there. It was definitely pre OSHA!
