I've been scanning Ebay, & tonight: just found a pr. of T.E. chambers

It looks like they bugger welded the tips back on.  The tips should be held on by a stud that goes through the center.  The studs have a tendency to twist off when you try to remove the nut holding on the tip.

Yes,I see that welding mess.
I'll need a person to clean that all up and reattach the end-tips so they can be removed at intervals to clean and re-pack them,along with doing what Mark said about hot-tanking them to clean them all out nice.
I also want that person to cut them open vertically along a welded seam,go in there and pop-out all the different dents:give them the 'full treatment'.
I'll get them coated w/ a durable product when I'm all done

I put a pair(from an R5c which was discarded during Spring clean-up in Hamden,CT.)on my 75' RD350B back in 1987' which were very gently used;I rode w/ an overloaded bike across the USA 2750mi. and love the Torquey response they gave my 350.
Now I'm hooked on this brand for an RD street bike.

I asked on my MX sites 1st as there used to be about 3 guys/shops including Nevada. They were always booked weeks out in advance and would stop taking orders to catch up. Good work and reasonable $. They are no longer around and no others recommended in the off-road world. Supposedly there's 1 in PNW and 1 back East but could not establish contact with them through internet searches.

I appreciate your search;I'm still striking-out..

it was many months ago when I inquired and struck out...

I think you are going to be really frustrated and ultimately disappointed in this quest. Cone pipes are not repaired the way you envision. Typically they must be cut apart at existing seams of individual sections and pounded out (or replaced with new similar rolled welded seam section) and welded back in place on the pipe.

Hydroformed stamped pipes are made in 2 halves and welded together lengthwise. FPPs are example of this vs. how your TE are made. These pipes typically are repaired using air pressure and heat to pop out dents. Sometimes people drill a hole opposite the dent, insert a rod and heat the dent while applying pressure on the rod to push out dent from inside. Another method is welding on a rod directly on the dent and using heat and slide hammer to pull the dent from outside.

That's just a basic overview of methods I know of and/or tried over the years. Not meant to be all-inclusive and/or 100% correct explanations of every technique or method used today. You can imagine the time and work all this takes and it won't be cheap if you find someone to do repairs for you. I'm kind of resigned to the fact I will have to repair my dented pipes myself when I get around to it someday 

If you are able to weld and perform basic metal work yourself that will likely be most direct route to fix your pipes IMO.

they can be cutapart and repaired, but it's a long messy progress. I've done it. the torque pipes are thick too, so a hammer and dolley, sandbag and some forming skills are required. me? I'd clean em up as best as possible, get them cooked out and cleaned, and go from there. it's going to be stupid expensive to pay somebody to do it right. like, about what a set of new Lomas or specii pipes will cost.  I envision about 10-15 hrs time at 150 ish an hour will get silly fast. or, buy a welder and learn how to do it. this of course doesn't include rechroming, if you want to go that way. I'm not trying to discourage,  just been there.  I spent a ridiculous amount of time on a set of fpps about a year ago doing it. mostly can repair. I like TE pipes , I've had them. but just depends. look for local fabricators in general. 0.02

I understand what you're telling me Mark.
Well, 'in for a penny:in for a pound'.. which is to say I'm committed to do this project;I'm looking for the right person to let them do the job;possibly someone who's retired(and still alive  )and had done it plenty before.
I may be able to convince them to do this work.
I'll keep searching.

not trying to discourage you, but anyone you find is probably going to want to do it the way they know best through years of experience and might not agree with your special requirements on how you want it done

hey, I get it. I've spent a lot on a bike that was worth next to nothing and don't regret it. reach out to chopper, and off road shops. you're going to find your guy 'outside' the normal channels I think.  good luck. Just be prepared to pay.

Yes,I'm in.
I'll keep looking for guys who do vintage off-road dirt bike restorations.

I recently repaired a set of Jemco pipes and that included a lot of hammer and dolly time and in the end I had to replace about half the cones. I still have a set  Bassani pipes that I don't want to even think about.  To be honest, repairing pipes is more trouble that it's worth.  The exception is MX pipes which they plug, pressurize and add heat until the air pushes the dent out.  I am not trying that any time soon either.

The Jemco's took me months because they were so frustrating to work on. My hat is off to anyone doing that professionally.

I imagine the toughest thing will be to find someone who will do it nice.

I've seen dents in pipes removed with air pressure and heat. Requires some way of really sealing up both ends.
I'd like to find some junk ass pipes to try this on in fact.

I live in a 2nd floor apartment w/ no access to a shop;so far I haven't learned much about welding and heating metals.
I imagine it's a type of 'art' to do this.

It's really just basic metal working skills. Have you considered taking a welding class? Like adult school or ROP offered after hours at Community Colleges? I started with small engine repair and woodworking classes in Jr. High School 1971. Then progressed to metal shop, advanced metal shops and eventually into auto shops in high school 1973-76. Of course, I had a natural curiosity on mechanical things since I was a toddler that drew me into this stuff. The point is you need to develop a basic understanding of "how to" bend, cut, form, heat, attach metals and practice until you are comfortable with it.

Please very careful and use proper safety equipment if you experiment with this. The most common method involves expandable freeze plugs on both ends - with a Schraeder valve on 1 end to add air pressure. There's lots of carbon and combustible junk in pipes that easily catches fire and produces tons of toxic smoke even if you are just heating or welding with open ends using a torch. This works best on thin metal pipes, but can burst open seams if you're not careful...
