Generator Rehab

#1

Post by LanternWerks74 »

Hi Gang,

Came across a generator which has some slight thread damage, the cap wont “start” as the very first thread is folded a bit. I want to be industrious here and use a die to cut/clean the thread and see if I cam salvage this part & hone a skill in the process. I have a thread gauge & it appears to be a 32 Fine. I don’t know how to read the diameter of the pipe & apply that to the correct die.
Can someone help me with this?

I have some dies, all too small. I need to source one for the job, but not sure how to go about making sure I have the correct fit.

I have measured the diameter of the pipe, which appears to be .3785 inch (3/8)

Having never shopped for a die (or cut threads) I am now in the weeds and require a bit of machinist guidance.

I’m guessing a suitcase stove generator?

From a practical stand point, carefully dressing away the side of the folded thread with a needle file might be the way to go. It would be the same as using a die to remove the fold, and you would probably have better control of the operation.

Yes, looks like the beefier 3 burner type of genny. It doesn’t mate with the stoves I have (all 2 burners). Not sure how it ended up in my extras stash.

Needle file is a good suggestion, I may go that route.

I would try a triangle needle file too, or get a thread restoring file that includes 32 tpi. Those files are only about 15 bucks, and will clean up a thread nicely.
Just FYI, a thread restoring file usually has eight different thread counts. Just make sure the one you buy includes the 32 tpi thread.
The thread restoring file looks like a square piece of steel with a different thread pitch on each side and each end of the file. Each thread file will work for eight different threads, and it doesn't matter the diameter of the thread you want to restore. A thread is a thread, in this case.

Listen to Dean. Here's a couple of thread files from my tool box. You can see the TPI stamps. These guys have saved my bacon more times than I can count.
