Perfecting the XM-18 3.5 Spanto Flipper?

I second Nano Oil, I was fortunate to receive a complimentary tube from my good friend Rubi, best stuff ever. Oh no I can see a thread coming, " what lubricant do you use on your Hinderer XM and why" forty pages to follow with chemical analytical charts under varying temperatures including drag coefficients.
 
Lubricants
Table 1 shows values for absolute viscosity and pressure-viscosity coefficient obtained from AGMA 925.1


Table 1. Absolute Viscosity and Pressure-Viscosity
Coefficient vs. Temperature

Temperature
EHL film thickness is established by the operating temperature of the components. For gears, the temperature of the gear teeth is relevant. For bearings, the temperature of the inner ring and rollers is relevant. A typical operating temperature for the gear flank and bearing ring and roller is 80°C. Environmental factors can influence the actual operating temperature.

EHL Film Thickness
EHL film thickness was calculated using equation 65 from AGMA 9251:



where

Hc is the dimensionless central film thickness
G is the materials parameter
U is the speed parameter
W is the load parameter
If geometry, elastic properties, speed and load are fixed, EHL film thickness varies with the pressure-viscosity coefficient () and absolute viscosity () as shown in equation No. 2:

Rubi I am having trouble selecting the lubricant for a CO2 reciprocating compressor form a fertilizer plant. Which cylinder oil to use? Wet CO2 produces a weak acid, which will dilute the lubricant, and will react with EP addtives forming deposits. ISO VG220?
Also how can i calculate the amount of dilution i can expect with the gas? Is it possible?

Thanks in advance for any help.

Joe - I'm going with... "loogie". Final answer.
 
Got it guys thanks, meanwhile I will be thankful for Nano oil and its's miraculous properties when used on my XMs.
 
My Spanto is Stiff as a corpse when centered. :grumpy: I have to loosen the pivot to get it out, however then it becomes off centered, it bugs the hell out of me. I also have a slicer that is smooth as butter and yet centered. The tension on the lockbar on the Spanto is much harder than Slicer, wich is in many cases sweet but it pushes the blade off a bit if the pivot isn't cranked down to no return... Don't wanna mess with the lockbar. Have tried centering tricks without result... Should i just crank it down and and let it break in? Both are new from Dealer. Tried different lubes, running CRK greese now wich is ok.

And Hi everebody im new here!:)
I live in Sweden (you know, Fallkniven, Gransforsbruks axes and more;) )
 
Welcome to the Herd!!

I would give the Spanto some break in time. Some people say they had no break in, others say they had to break in...
 
Lite look in the stickies, you will find a guide to centering, my preferred method is with a folded business card between the liner side and the blade, with all the handle screws loose, tighten the pivot to where you want the tension then tighten the handle screws from the pivot to the lanyard hole in sequence....has always worked for me.. hope this helps, I know many others have other ways of centering and they also work very well.....thats the fun of owning a hinderer, it's tunable, like a fine racing carburetor(oops my age is showing)...

Hi! Thank's for the tip. :)

I have tried similar methods but i will give your tip a go!

Thank's

Love my Hinderes any way :thumbup:

And i will check the stickers, i learning (hopefully) to search subjects thats has allredy been covered! :D
Thank's
