we all do small odd jobs not really worthy of starting a dedicated thread for but might be interesting to some of us so I figured I would start this thread to hopefully get some extra activity on the site. so this thread is for everyone who wants to snap a few pictures of what they did threw out the day to give the rest of us something interesting to look at in the evening.

My buddy has a 1971 GMC 5500 with a cummins from a 93 dodge pickup it and he used the intercooler from the truck during the swap. it was corroded and full of pin holes and finding a good one came up short, in fact I have 2 more buddy's that now know they have the same problem! bigger intercoolers from heavy duty trucks are relatively easy to get so I cut half the core out of a cooler from a sterling truck that had a C7 CAT engine. its a little wider and thicker but it worked, and theres enough left to re-core one of my other buddy's coolers also.

the 2 coolers


pressure washed the sterling one.


cut tanks off dodge one.


cut core from sterling.


welded the tanks on.


not the best TIG welds I have done but there a hell of a lot better the the factory welds next to mine!

it looks like you could all most get 2 of the truck coolers to fit the dodge sides.

There is enough core left to do another one which I will be doing. The next one will have 1 or 2 tubes less then this one but it will be going on a stock engine and the core is thicker with bigger tubes then the factory dodge core so it's shouldn't be an issue.

rainy 4th of July here in MD, just did some internal cleaning house,sorted and rearranged 'inventory',cleaned out a storage sea container,tested some generator ends(failed megger insulation test,put on scrap pile,not worth rewindin)-but scrap is bring next to nothing right now.Kinda of an inside shop day today,sorting nuts and bolts LOL

No pictures, as they wouldn't show much everyone here isn't familiar with. Changed the oil on my recently engine swapped generator. This is a weekly event. But this being third oil change I added a heaping teaspoon of molybdenum disulfide powder to the oil I put in. This is a one time treatment. Last engine I applied it to got over 4,000 hours on it before it packed in.

New -real- gas cans arrived. Take some getting used to, but I already like them better than to old plastic -CARB- cans.

Hey Doc

What does the molybdenum disulfide do? Make the internals slippery?

It's the moly in moly grease. As it was once explained to me by a fanatic bimmer mechanic; the molybdenum bonds to the metal parts, -ionically I'd guess- then under conditions of lubrication breakdown where you'd have metal to metal friction, the sulphur shears much like graphite. I don't know if that really happens. I do know that the last engine I treated with it looked almost new inside after 4,000 hours when I tore into it. The failure that took it down wasn't friction wear related. (A loose compression release pall beat the crap out of the cam drive gear till the teeth bound).
I'll post pics of the bore and piston once I find where I stashed them.
Doc
Oh, I already posted them. See post 14995 in the spring weaning thread.

some more aluminum welding, just the normal weld up the cracks and lose rivets in an aluminum boat. this boat had a rough life by the looks of all the dents in it, some really bad ones on the other side!

I always hated welding aluminum boats because the grade of aluminum they use is usually garbage. It's usually a lot of recycled stuff. One spot will weld great then a spot next to it lousy. I used to weld the john boats from the recreation department on my Air Force base and hated it. Backup gas from the back side, copper backup plates with shielding gas, nothing helped the inconsistency of weld quality. I even built a tent out of welding blankets to keep drafts off my shielding gas. It's danged embarrassing to supposed to be trying to train somebody and have something fight you like that. Recreation had 12 boats of that type and I always felt the urge to run when they came dragging one in. I haven't tried any others than them, I hope yours comes out great. Sorry, your pics caused me some serious flashbacks! LOL!

Ive been welding aluminum for 25yrs and have to agree,but when you're training someone,what a better way to teach them that all is NOT as it appears.Having to fight with bad material content is an education in itself..kinda makes you appreciate new material fresh off the rack.I once constructed an aluminum walkramp for a custom trailer.(1)had bad shield gas;(2)material was recycled,had impurities and dirt in it;(3)welder(Syncrowave)had control issues in the middle of the job-rough way to start the day

Thanks Doc

I saw the previous shots and was impressed by the look of the bore and hence the question about how the moly worked and what it was

Doc Where can you buy the moly?
Thanks

This is probably the cheapest route to just try it out.

I've had a one pound bottle since high school, which Amazon also carries, but ~$90.

Odd jobs...
Oil change (again). Replaced failed hour meter on small Gen. Inventory and organize storage unit. Build more soda bottle and stinkum fly traps (folks across the street train and care for horses. Fly population exploded!) Track down crimp terminals. Test AC on new 4kw Gen. Lube car lock mechanism after car locked itself when I last got out. (Spare key) track down a manual for tote goat Nova.

the frame on my truck is getting a little thin so I added two post that bolted to the bumper and welded to receiver hitch.

I picked up a 2 gallon air tank that had been a small "inflater" compressor. The compressor was toast so it had already been removed. My first goal is to cap off extra ports and make it just a transfer bottle. There are two gages and an adjusting valve but it seems leaky. I'll have to clean and see if they can become usefull. I only have 12 volt compressor which is pretty slow. Now I need to find a good compressor with a leaky tank. Maybe a repurposed frig compressor.
also got an LED task light for the welding cart and an old belt sander to try the motor out on a grinder I found. So I perpetuate the age old issue of many starts and no finished projects.
I did finish a great scooter ride in the NC mountains thisafternoon.

i think i read you could use a car ac pump four an air compressor.

When I moved into my property the previous owners had left an air compressor with motor but no heads on the pump. For a long time I used one of the round GM A/C compressors that pumped up pretty good although the intake was awful noisy. Had an air raid siren sound. There were about 50 window A/C units with the coils already cut out in a pile, so I got curious and cut the compressor on one open. The head on the pump looked about the same size as the missing heads so I made a couple of adapter plates out of aluminum and put them on. The plates dropped the compression down some but it worked for several years until funds were available for an 80 gallon store bought unit. Just be careful when you cut open the window unit compressors, I used a torch and didn't pay attention to where the cut off outlet tube was pointing and got a hot oil bath on the underside of my arm (above the welding gloves that came up to my elbows!)
Yes, I bought the property real cheap if I would clean up all the junk instead of the old lady that owned having to. The list goes on and on and......

Bunk
My brother used to work in a motor rewind shop in his early days. Whenever he found an old motor he ran a megger test. If it failed he would flood spray it with transformer spray and then let it dry thourly. A few days later he would re run the megger test to see if it helped. Most of the time that was all that was needed to put the motor back in service for his own use.
