The Wall of Shame.......Has come down

[Flash]

I had planned of tiding it all up.....but never got around to it.


But now the shame it's gone!


spent a little extra time on it this time!
built all my mm oil gauges on a 4x8 sheet of particle board, that is build as a seperate piece from the bench.


But is meant as a backing board for the bench.

here it is all put back together

I made them separate pieces so i didn't have to level the bench.
The back board has one large bolt with a nut pressed into each 4x4 leg. screwing them in and out will level the gauge back board. one bolt on each side.
And when i build me a real "P.T.S". flow bench.......the back board is already done
once i decide were to mount the motor controller....i can tidy up the wiring as well.

Looks good bro. Nice size garage, too bad its sssooooooooooo cold in there!

Looks good. I like the idea of the back board separate from the main bench. I put my bench on rollers this winter and made it much easier to move around when cleaning up.

Thanks Chris,and Tom
It a 40X40 3 car Garage. some day i hope it will be 20 X40 shop(a little easier to heat!)

I originally was going to attach it to the bench with a swivel in the middle to level every thing.

but i thing this will work out better as well.

All the gauges are 3/16 OD vinyl ......think i when to small. all the gauges are slow to response.
Only had but a moment to play it then though. Will know better how it all work tonight.

although my gauge are already set up and have mm oil in them.......I ether have to go with a larger vinyl tube.............or maybe its just the 15* garage temp that i have been testing it.

The question to my self is, What is the viscosity of the mm Oil and the Dot 5? I can't seem to find that info, it's probably based off of a 60*F any ways

So tonight i will be making up 2 simple/quick U-tubes and tying them both to the same vac source and see which fluid flows better in a 3/16 tube. at 10-20* above 0

mm Oil is just to slow acting in the cold, so i will have to rebuild my gauges with larger hose.
and if i have to do that, Well, i might as well switch to Dot 5 Brake fluid.........BUT WHAT HOSE WILL WORK BETTER WITH DOT 5................I hope to have a solid answer tonight! <----------they need a Mad Scientist Icon

Thanks Malvin, but it's the dot 5.0 (SILICONE BASE) that I'm using.

and i wanted to compare it to MM oil

The close to mm oil, or "MMO" was a comparison to 3 w eng oil.
found spec on a 5W oil
MOTOR OIL GRADES:

SAE Motor (ENGINE) grade
ISO grade @40°C
Cst @100°C (assume same as 210°F)


32 = 28.8 to 35.2

this info don't help much as this spec is at 100*C
and the info above is MM/s
