Two months ago ,when cleaning on of my arms I’ve noticed that two of the bearings are in bad condition.
So ,I’ve ordered all the bearings (without the trust bearings) and new specially treated axels, so I can re-anodize and re-paint every part.
So far so good….But what I have found when de anodize the parts shocked me: Cracks all over the long sections of the arm ,especially where the axels and the bearings are.
I’ve ask a “specialist” ,who told me that those can be welded and will work fine. Hmmmmmm…….
Tried on one of the sections ,but I did not like how it looks.
So the dilemma was : to save this arm for spears, or to order a new sections .As I’m not really a rich guy and the arm with my back-up sled where already for sale ,I’ve decided to make new sections .
It took the machinist almost two months, but yesterday I had them and send them for anodizing.
Do any of you guys seen this before?
I know IIIa/Luna arms are old ,but this….

Hi Nikolay
I would contact Hugo from steadiRig as he may have several 2nd hand bones which he may be able to sell you at a good price or he may even be able to supply you with 2 new bones .
Good luck

Well done. I'm curious to know how much it cost you to have them machined and finished.

Unfortunately they cost me too much (1100 eur without the bearings), but I did not have a choice.
The good part is,that now I have the file with the drawings,so if anyone need some....

I think thats a pretty good price for all 4, considering you have about 60% of a full arm there...

Rick,
You might be right!
It was just too much in this moment for me.
I'm going to put all together now and see the result...
