Very quick job today.
6 rods in stainless. 12mm dia, 30mm long with 20mm turned to 6mm and threaded M6x1
One side to be milled flat so I can drill and tap 2x3mm holes for fixing some flat brass strip to.
This was the third design I eventually decided upon.
Turned the 6mm dia, threaded the end m6, parted off to length, repeat till all 6 were done.
Then I reset each rod and rounded the end with the curved part of a router bit
Then mounted each rod in a tool holder, set the height and using a 10mm end mill to face off the length of one side. Repeat again.
Start

finished in one pass

The 6 finished parts with the router bit I used to round over the ends.

These will eventually hold the spiders on the giant binocular.

I only had about an hour to work in the shop last night so I fabbed up the mounting brackets for my power steering oil cooler.

Here’s what I started with, a 3” long piece of 2.250” diameter x .120” wall tubing that I cut in half lengthwise to saddle over the 2” diameter cross member and two pieces of 1/4” flat strap.

Saddles welded to tabs after drilling and tapping the tabs to match the coolers bolt pattern.

WOW, that thing is filthy under there and needs to be detailed.

Bead blasted, painted and ready for installation.

Thanks for looking.

wouldn't attaching the cooler to the exhaust pipe actually pick up more heat from the exhaust? I would think you would put it away from a heat generating component.

EDIT: it's been pointed out that it's not an exhaust pipe..

Not sure Jeff, but it looks likes it hanging under the front part of the engine. maybe that is a tube that is part of the frame. ???

No thats an exhaust pipe for sure

Then the "exhaust pipe" has a hole in it near the right hand bracket...

 

[Brento]

Nope im wrong now that i looked closer at it. It looks like its attached to the nose of the vehicle. The giveaway is you can see the belts and pulleys. Prob support for the radiator. @Bill W. @woodchucker

Agreed, in the standard view the image info blocks that, but using the full size function, I see that now.
Obviously not an exhaust pipe.

I installed a couple of inexpensive DROs on my 9x20. I can get them to register .0005" of movement even though the rated accuracy is .001" - which may actually be true but I didn't expect that they would increment in .0005". Not too bad for $60.

 

[kvt]

so what ones did you install.

Those inexpensive scales are actually 10 micron scales; .01mm or .0004". I used Yuriy's Touch DRO for 5the readout on mine and set the resolution to four decimal places. The readout steps in increments of .0004". Depending on how the math works in your readout (does it round to nearest .0005" or round down or round up), that last .0005" may not be accurate.
