Made some new VM26 fuel transfer tubes

[sschering]

I got the lathe working today so I made a few parts for the GS.

They are new fuel transfer tubes for the VM26 carbs.. The old rubber hat seals were shot and they dont make em anymore so I made some O-ring type tubes..
For the T fitting I just made aluminum hats to replace the rubber seals.. I'll epoxy them in place..

OOOOoooooooOOOOOOOOOOOOOOooooohhhhhhhhhh!

Purty!

Nice work.

 

[gsgeezer]

Beautiful they look great

Just did that myself the other day for the tranfer tubes but dont have the T. Looks great man

Great work on those parts.

I used to have a South Bend 9" but sold it before moving across the country. It was pretty sloppy but dang I miss that thing. A machinist friend help make the T shown below (for a 550); he turned the main body and I brazed in the barbed fitting. Works like a charm. There is some place selling these parts on ebay but they want quite a bit of money for them. Best to make your own!

I was going to make the whole T and braze in a fitting like yours but I wasn't able to find any brass bar stock over the weekend..

I found some 1/2" aluminum bar and went with this plan..

How wide and deep did you make your O ring groves?
I need to go back and cut them a little deeper and wider.

The fitting are .429" OD. Just about .004" under the 11mm (o.0433") bores in
the carb body.

I wish I could say I did a great job on my first try but there are 3 more pieces I totally jacked up before I figured what I should be doing hehe.

My Lathe is not exactly your typical lathe..
The slide rest and tail stock are Elgen but my grandfather made the rest..
Bed headstock and all..

I can't remember how deep the O-ring grooves are but you need the diameter inside the groove to be about 1mm larger than the O-ring ID. My machinist buddy is a perfectionist and made the grooves rounded on the bottom although I don't think this is necessary.

I found a nice page on O-ring groove design..

Nice! I admire your ability

Two years ago I had to replace the fuel tees on a GS850...

Insanely expensive!

 

[trippivot]

excellent

excellent

very nice work I must give you 2 thumbs up. might be a fortune in selling those parts.

 

[rapidray]

Know how to make a fortune making & selling motorcycle parts? Start with TWO fortunes!!! Ray.

 

[sschering]

Don't laugh. this is the lathe.. My Grandfather made it from a few elgin bits and the rest from scratch.

 

[sschering]

The final product installed..
Just for fun I turned the centers down a bit.
Can you believe some guy in Ebay is getting $40 for each piece? $120 for the set. crazy

If it works, it works. Cool machine.

What are the belts made of?

Bi-directional, multi speed. Nice and simple.

Good picture of some stock VMs.

Hmm thought I answered this but I don't see the post..

The belts are Accu-links.. polyester reinforced urethane..
the bet is make up of little links that lock together..
You make whatever length belt you want and they run smoother than a standard V belt.

I'll probably play around to see if I can make a good complete T without having to turn down a stock one as a starting point.

I'm looking at either using a 3/8" brass PEX crimp fitting as a start or making an all aluminum piece and using alumaweld rod to put it together.

Nice work...being somewhat of a hobby machinist myself i can appreciate those little touches that really make the bike unique...very cool..love the lathe too!

Cool.

I have an old 1940s Southbend lathe needing restoring, and belts are one of the things I'll need for sure. It originally ran off leather belts.

Accu-links, that's pretty slick.

Thanks.
