The revival of 650143R, 1970 with TS.

[Richard48Y]

Triumph forum has a lot of complaints about the rubber boots falling apart.
For only $5.00 I am going to try a set of Energy Suspension 9.13105G
I expect the poly will be more durable.

Started on modifying mounts,
Cannot complete them until my parts arrive on Wednesday.
But that did get me to thinking about fitting the new seals to the transmission.
Which has me wondering where to get the bellows type seals for the rear shift link?
Would be nice to not have to wait for another slow order from France.

Heard from Nitrofreeze this morning.
Seems they have a $90.00 minimum, I should have sent more pieces.
They also use UP$ for shipping, nearly $40.00 for a simple timing chain and gears.
I only spent $8.00 shipping to them via USPS Flat-Rate.
I have made payment and should have the pieces back next Wednesday.
Then I should finally be able to assemble my engine.

  I fell you pain. wait till you have a internation shipment

Still beating my head against this obstacle, WHICH alloy to use in making new transfer tubes?
No idea what the tubes RD Ent., and others have are made from.

Stainless 304 was not good, maybe in a fully annealed state?
Aluminum 6061-T6 is also useless, maybe T4, or O?
Of course the useless alloys are all that is readily available on-line. 
Someone should have the alternatives in stock.
I expect to have to make a long drive to pick it up once I find a source.
FYI, just buying transfer tubes and having them shipped appears to be about $900.00 now.

I bought mandrel bends etc and welded it together…..

[Richard48Y]

I have the bender, dies, and bad eyes.
Would not be able to trust my own welding.
This has now become a challenge so has to get done.

[TurboFource]

My local NAPA said they could bend up to 1-1/4” tubing .. maybe a local shop could do them?

[Richard48Y]

Almost anyone can "Bend" tubing, it is getting clean wrinkle free bends that is a trick.
For exhaust they actually make dies that force the crinkle at the inside of the bend.
Mandrel bender is silly expensive or I would have one.
From what I have been able to learn I just need to find a source of annealed material.

[TurboFource]

This was for hydraulic lines … I don’t think they crinkle those that I have seen …. they closed the shop here so I guess it doesn’t really matter

Just trying to be helpful

Our transfer tubes are a bit odd for size which also limits material availability.
I am at the point where I want to put them in now so annoyed this is being difficult.

Why don't you want to use AL?  The last set I had made were bent up from the proper size galvenized exhaust pipe, for what it was worth.  I have a set of AL pipes here that will certainly last long after I've gone west...and the system is only running at 7lbs pressure.  Originals were mild steel...and lasted how many decades?  Installed properly, I've no doubt that they would outlast any of us building these buggies.

The pipes are isolated from the chassis in grommets...so (should be) no dissimilar metal contact for electrolysis.  I have a set for the TC: 6061-T6, 1.25" OD.  Mandrel bent, no ridges.  Will probably give them a light alodyne and zinc chromate (Yes, I have the PPE and booth available to do it) anti-corrosion treatment. Can send photos to comfirm. 

[Richard48Y]

I am fine with Aluminum if I could just find material that would form properly with my JD2 bender.
It seems 6062-T6 is too brittle and T4 is unobtainium.

[Bryan Boyle]

Rich:  Sometimes it is worth finding the craftsman who can do the job right.  They are far and few between, especially now days when everything is just rip and replace.  Building from scratch is becoming a lost art.

These pipes were bent by someone who knew how to use a mandrel bender properly (last photo is the material type).  The extra cost meant that it was done right and the angles are what they are supposed to be.  Seamless 6061 pipe, bent properly in a hydraulic mandrel machine using the originals for a pattern, may end up costing less in time and materials than trying to figure out an alternative solution which may work, but not as cleanly. 

No criticism of you or your thought processes...but having done this a few times, it's worth the extra effort in the end.

Good luck!

I am out the back of beyond with no one reasonably nearby.
Even Reno appears to have no one beyond muffler shops.
China-Virus wiped out most of the craftsmen.
I've got both tubes fully drawn in Bend-Tech 7 as well as my samples.
I am confident I can do this as soon as I locate suitable material.
As a last resort I may have to buy bends and weld them.
Just cannot do $900 for such a simple part.
