Truckers Monster Rebuild

You realize that's not a wheel...right?

Well duuuh, hence the single quotes. It's a hemispherical hub like the one on the 748-916.

[Rameses]

hemispherical

Nope.


And like truckinduc said, it would probably be strong enough without any of those spokes in there at all.

There's enough meat shared where the inner and outer circumferences meet to do the job.

The part isn't undergoing any rotational forces, only straight line.

Same idea but different forces. A single sided swingarm has to cope with all the forces in a single arm-hub. these are eccentric hub adjusters.  If it were for a single sided swingarm It would be much beefier. Since the load is distributed and shared between two arms, with quite a bit of space inbetween, the forces are not as concentrated.

Its an eccentric hub.  I never understood that verbiage.  Acentric seems more logical, and is a synonym for eccentric.

Maybe someone who's truly learned could fill us in on the etymology.  make the beast with two backs Google: I'm not looking it up.

Eccentric, not hemispherical!   Bah, curse English as a second language!

I understand your point, but I would still be concerned. If the frame can crack, I think the adjusters might as well. Look at the eccentric adjuster for the rear shock on the Bimota DB7 for example: they shave a lot of material off, but it's mostly full.

Let me also point out that I'm not trying to put you (or your work) down! I really admire what you're doing and what you've already done with your VTR project. Keep it up!

[truckinduc]

No offense taken. I guess im taking it to the limit! 

Frames crack because of ducati's welding techniques. 

[truckinduc]

so I should have made the eccentrics today, but I didnt.  Ive been dying to get started on my exhaust so I finally did.   Lots O cutting and Welding.  Its going to be ALOT of work but worth it in the end, in my opinion anyway.

[Ahks]

for a very novice welder like myself that looks like a nightmare lol.
Make sure to get a shot of it off the bike too so we can admire the handiwork

[truckinduc]

well its Titanium so we will see.

[Ahks]

o rly now. THAT is spectacular.

[one]

been reading this since morning....(Malaysian hour  )

well,like everyone said,you are great at what you did...
you did it well,clean and neat...

with all the utilities and machineries,wow...u have that at your home...cool..

btw,how's the price like for those Ti tubing?

ps:sorry for the bad english

[truckinduc]

Thank you. Most of the machines I use are at school.

I got a good deal on all of the titanium at the junkyard, I paid 1$ per pound.  So ive got about 30$ in my exhaust so far.


That being said does anyone have any rashed up Ti mufflers?  Im looking for one to cut up and make my muffler out of.

  Looks like that will keep you busy for a while.   Can't wait to see the finished product.

I don't have any extra laying around, but I'll trade you my dinged-up remus TI hi-mounts if you've got a suitable alternative... Arrows, CF cans, something... I'd take CF low-mounts if you had some knocking around, I'm not too picky...  One of the cans is pristene, one has a depression from a door opening into it... pics available if you're interested.

BTW, what's the skinny on welding TI?  I've done some basic ARC, MIG, and oxy-acetylene, but heard TI needs to be done differently?

Thx!

[truckinduc]

Ive got nothing. Oh well.

For Ti to be done properly it needs to be welded in a vacume chamber, or argon or helium environment.  When the material gets above 800 degrees f it becomes contaminated if exposed to oxygen or other elements in the air.

You can get away with lots of shielding gas and purging the inside of the tubing. This is what ill be doing.
