Kellogg Compressor Head Repairs 

Reminds me of the slogan on a handyman's van. "I repair what other people 'fixed'."

how do you get the valves out? Special tools?

@Mike Williams I made a tool with a piece of pipe and a grinder with a cutting disk.

@@mythril4 I will give that a try!

If I squint I can see me doing that quality repair!

+greasydot What I love about the job shop, it's a nice variety.

I own a powdercoating business and use the same IR gun. I can tell you from shooing parts like wheels lets say that have narrow spokes, lug nut holes in the center of wheels, and so on. Where if you aim the dot at say the center hub of a wheel where it has the most mass which will take longer to get up to temp in my oven, the cone will partially be on the wheel surface and some of it will be shooting past the wheel and hitting the oven wall a few feet away. Which in your head makes you think its not an accurate judgment of temp, but from actual readings from inches away to a few feet away, it honestly doesn't fluctuate enough to matter. its not like 6 inches from the wheel and getting all of the wheel in the 'beam' will say 385deg and then I step back a country mile and all of a sudden its reading 265... its honestly +/- 5-10 deg max. Now, that being said, the Kline IR gun Adam and I have, honestly, sucks. The reflectivity of the coating or the color makes the temp reading swing a country mile. Satin black reads the most accurate, gloss black would be next, silver or 'chrome' powder base is a mile off from actual PMT (part metal temp), white is pretty bad too, other 'darker' colors are somewhere in the middle. Not to mention mine is over 35-40% off! I can coat a thin metal outlet cover (I shoot these as demo swatches for people to see and feel the powdercoating colors) which will get up to part metal temperature in minutes where an alloy 20" wheel might take 45-50 minutes... I hang the outlet cover an inch away from my thermocoupler which feeds oven temp to my PID oven controller and where my PID reads 400 deg in the oven, 20 minutes later my outlet cover would have undoubtedly been fully up to temp and it reads 285 with the Kline IR gun 2 inches from it or 2 feet from it! Its incrementally off from what I have tested and found, so bad that I have a chart I made with IR gun temp = PMT written out on the side of the oven! I am too lazy to toss it in the garbage and get a better one because I adapted to it at this point. My thermocoupler is dead on, and I verified PMT with clip on K type thermocouplers too. I don't know if I just got a bum IR gun or they are all that shitty from Kline. On this casting video I would have like to see a few temperature pens used then shoot the line where it drew and melted out on part with the IR gun to compare the results.

I use mine for measuring temperatures on the drum of my coffee roaster. I also have a contact thermometer that is calibrated so I can check against the IR thermometer. In my case the difference betwee 1" away and 6" away from the drum is enormous. At 1" the reading is very close to the measurement of the contact thermometer, at 6" it is lower by about 40%. This is on an 8" drum at about 200 °C.

same Kline ir gun? I will have to shoot a video experimenting with mine next batch of parts I toss in.

I actually have a Kline and two other ones and they all show about the same characteristics. It makes sense when you look at the cone.

I use the same Kline gun. Bruce is correct about the cone. If you look at the side of the gun, it tells you how big the spot is based on how far away the gun is from the surface.

...and he used a Harbor Freight pick LOL...I have that same set. LOL.

Standard flair fitting. Nothing special at all.

+Andy Coakes Thanks Andy!

Thanks Rooster!

+dkroth Everytime? You learn from mistakes bud. 👍🏻

+ken cunningham Thanks Ken

The place I mentioned is a good source for hose and fittings

+Abom79 Sorry, I guess I missed that one. Oh well. Not having a good day anyway. Thanks Adam. Nice work as always. John

The "flared" end appears to be spherical versus standard 45 degree flare though.

We call it a ball because it is shape like a ball. I machine from 1" to 2" flared adapters and couplings on my line. That is a smaller fitting it's done on a smaller machine. We also make the tube nuts for them as well.

Jimmy.. is that ball fitting a standard in any particular industry. ?

+Doug Bourdo 1/2"flared× male adapter is what called on the print.

Is it also considered 1/2 inch NPT to 1/2 inch JIC fitting?
