Straightening a gen tube the Hippie way

#1

Post by Gunhippie »

This one isn't horribly bent, but why not take a minute and make it straight?

Image

Put the tube between two fairly heavy, flat steel plates, with the flare hanging off the edge:

Image

Roll the tube between the plates with gentle force. As it gets straighter, you'll feel the bumps reduce and can add a little more pressure. Just don't go all ape and crush it!

Image

It took longer to find the top plate than it did to get the gen nice and straight.

Oh, yeah, check for this:

Pricker bender booby-trap. You can't see it looking down the tube, so run a piece of stiff wire down from the tip end. Toss it--it serves no purpose but to sell more gens.

I found the "booby trap" in a 502 I fettled a few weeks ago. Man, I'd hate to bend a pricker wire on a 502 gen because of one of those stupid things.

Did you make the post about it? I would never have looked otherwise.

I didn't know they put those mesh things inside the generators.

They seem to show up late '60s or so. I haven't really kept track, but I now check for them in every gen I rebuild. They are guaranteed to bend a pricker wire if you try to insert the pricker with a screen installed.

The fact that they seem to crop up fairly late in the history of Coleman kinda' belies the idea that they are there to filter fuel as Coleman and other camp fuels became available in the mid-to late-50s.

I use the steel plates because... well, I'm used to using steel plated to straighten pieces of metal. But I can see the wood getting better traction and having less potential to damage the soft brass.

i have learned to use wood on a few coleman things repairing em , especially the nickel ventilators , i have a few special wooden tools just for that . doesnt leave any scars just have to get creative setting up the push or roll depending ....i can usualy make those vents pretty straight ..... mostly just cuz there brass and easy to manipulate compared to steel .

Just my opinion, but I don't the generator screens had anything to do with fuel quality or fuel filtering. Most likely the screens were included to catch the carbonized material on the inside of the generator that flakes off when the generator expands and cools during operation. One can throw away the screen, but then one may spend more time in ritualistic cleaning lever spinning during a startup clearing flaking material out of the orifice that may have been trapped by the screen. YMMV

Good tip here man. I’ve rolled by hand before and gotten good enough results, but this one is a keeper.

I remember my first bent wire because of that aggavatin’ dadgum screen. But I still reinstall them when I find one. I put them on the pricker first before replacing them in the gen tube. Definitely not necessary but what the heck, it gives the next guy something to cuss about.

I usually run a .17cal bore brush in the tube during cleaning which gets the screen out easy. 17cal is for pellet guns. 22 cal I think was too big. For straightening, I made oak jaws for my vice and I gently squeeze and turn a bit, squeeze and turn, etc. Don't know what to due about a dent in an R55, but the pricker shaft moves ok and it works.
