rare gs swing arm ad spotted

[nlovien]

maybe of interest to add something a bit different - http://www.classic-motorrad.de/classifieds/racing-teile/racing-teile-in-romeitaly-and-pragueczech-republic_i14081

Yeysus that's cool, needs some work, but finding another one would be impossible.  Wow. 

[Dezza]

Very unusual. I wonder who made it.

[Rijko]

love it. Seller has been trying to sell it for over 2 years now and keeps reposting it.
Looks like he does not accept anything less than 400 euro and shipping from Italy is expensive.
Everytime i see it my greed plays up but total price is too rich for me

Limited Forging sites for Mag in Italy at that time.

Probably a Private commission, but Campagnolo must have been involved.

Well somebody needs to feed back the costs of recommissioning that.  MagnaFlux inspection,  detail welding and repair, re-Chromate. Not available in Italy/Croatia.

:lol: PM and I can probably get it sorted.

stfu Mark 

Have been eyeballing that one for a long time now, you're feeding my greed !
Swingarm would look great with my other magnesium parts ...

It's whispering to you. 

[Rijko]

dammit it is ... but including checking/refurb that would make it a 1000 euro swingarm.

fatal attraction at work !

[markfoggy]

Well, probably the only one left on the planet. 

Is never going to be cheap.

Seriously  Mark?

There's more places to get castings done in northern Italy than there are places to get Pizza, look at any Italian racecar/bike from WW2 on.

  Not shortages today of places over there to get it checked over and rechromated either.

[markfoggy]

Well yeah, you may be right, is just more difficult if you think of it from bike world. Can you help this man out and get him some contacts for a guide price?

 

[Rijko]

i'm not cheap, but i am out of a job atm ... guess i'll polish the heck out of a 100 bucks GS1100 alu swingarm

[markfoggy]

Rijko, as you pointed out, it's not going anywhere. 

[Gammaboy]

Man that's a nice casting.

There's a makers logo on the underside, can't make it out though - wonder who it is.

Campag were probably the biggest supplier of Mag castings, but there was plenty others in the 70's.

[Gammaboy]

Thinking about what you can see of that logo - it's familiar, but I can't put my finger on it.

Thought maybe it was Segale - he loved cast mag swingers and eccentric adjusters, but can't find a segale one that looks the same.

[Maggo]

Nice looking - but a bit too much russian roulette for me

[Solcambs]

Seller should get it checked and sorted .. then the price tag would be pretty damned high I would suspect!

[canamant]

No way Jose.  Cast magnesium of that age ?  They let us run modern wheels in the Classic TT because the cast magnesium ones are known to turn nasty with age.  I'd put that swingarm in the same category.

Magna flux? On a non ferrous material?

[markfoggy]

^ yeah you got a point, my bad. Got a mag brake hub looked at a while back, can't for the life of me remember what was done to it. Bit more than penetrating dye., was a contact from Dymag when they were offline for a year of 2.

[Reinhoud]

May be ultrasonic testing. But whatever testing you do on it, I wouldn't trust it. With all the testing you can do on it, they're all to find porosity or cracks, you can't find out how strong the material is without breaking it. You won't find that with NDT

[dupersunc]

Die penetrant is most common for Mag castings, or eddy current if you're feeling flash.  Eddy current will get under the surface, which Die penetrant won't, but from what I've seen and been told of  old mag castings, 99% of the time flaws you pick up beneath the surface have been there from the casting process, so tend to be disregarded.

I tend to agree that swingarm is best seen as a curiosity rather than a useful item.
