Hillbilly Engineering

Some PE and PP can be welded with hot air, I had a broken component and V'd out the break and used a small butane soldering iron/hot gas source and welded the part much like OA and used strips from a PP milk bottle top as filler rod, worked fine and is still good  today after about 20 years. Another try on a different grade of material got no where so I gave up, it just seemed to soften and char but wasn't playing ball, maybe better kit would have helped, maybe not, I don't know. At least one attempt came out OK.

To the best of my knowledge, the motor fuel of today bears little resemblance to the gasoline of fifty years ago. The top end Shell product claims to be ethanol free and is the only fuel I will use in my antique mechanical sheep.

HiTack cleans up with ethanol. - not real well, but the stuff is definitely not alcohol resistant.

Calling today's regular grade motor fuel "gasoline" should be a punishable offense - - - -

Huh. I would have thought the Permatex engineers would have been able to tell me that, should have been aware if 10% ethanol would defeat their product. Never had ethanol on hand to test it.

Thanks.

I've asked tech support personnel many chemical questions they can't answer, such as the organic acid resistance (tomato juice) of Omega's stainless and Inconel thermocouple probes. I special-ordered an Inconel probe to monitor stew simmering on the wood stove but didn't find a good answer to which was better on the Net.

Ether starting fluid, methanol and isopropyl dry gas, acetone (nail polish remover) and lacquer thinner have similar solvent properties. Mouthwash, 70% rubbing alcohol and vodka may contain too much water.

Use PermaShield for fuel component gaskrets - also a Permatex product. It specifies it is resistant to ethanol.

Hi Tack does not

No, you don't.

I once tested coupons of D2, 316L, a 400 series, and inconel in molten adipic acid overnight. The D2 filled the jar up with rusty precipitate, the stainless steels all showed precipitate and major attack. The only one to make it was the inconel.

I ordered, installed, and ran a very expensive 40mm W&P twin screw extruder on the basis of that test. One combi feed barrel was $40K alone. Mid 1990's.

Thanks, that's a good data point. I forgot to mention the citric acid from the meat marinade.

Which is "them", cheap or H&S? I seldom used my old electric Remington 14", but it lasted at least 25 years, before the plastic lugs which held the bar straight sheared off. The new one has a dozen years on it now, I guess. I took down several small trees at my sister's house last summer. Those things are built tough.

I gooped on some of the $1.50 HF epoxy onto the long cracks in a Mantis tiller gas tank my sister gave to me. The first time didn't cover enough so I cleaned it and added more. 2 years and holding!

I had a roll of that modeling clay gas tank epoxy which had hardened up on me after only 30 or so years in my junk drawer. They don't make things like they used to.

A pawn shop owner gave me a Remington that had been outside his shop under the snowbank all winter, abandoned there after he wouldn't pay what the previous owner demanded for it. It still ran and passed 500V hipot testing and the rusted chain and bar could be freed, though I replaced them. I did consider putting a handle and on/off switch on the top but the case doesn't seem strong enough.

My knees and back stiffened up after 30 or so minutes scrubbing the kitchen floor today. They don't make me like they used to.

Actually those are injuries from high school sports that never fully went away. They make me feel like a teenager again -- sore in all the same places.

Ditto here. I distributed a load of chips on the front "lawn" this last week and I still feel it in my shoulders and lower back, like I'd rowed from England to France or sumpin.

LOL. I'm glad most of my old injuries don't bother me.

It'll likely take me a while to "recover" from 3 weeks of holiday/travel. Not used to walking 8Km a day on cobblestone streets, and sitting in airplanes for 9 hours at a time. Using the cane made my hands hurt - not using the cane made my back/hips hurt. At least using the cane shortened a lot of lines - - - -

And if you're smart, you can use one which is tactical, too, JIC. Where are there cobblestone streets, London?

Rome. Florence, Athens,Kotokolan,Rhodes,Fira, Oia, Mykanos, Heraklion, Olympia, Ephasus - all places on my itinerary on this last trip.
