Wheel refurb

<< < (2/2)

K2-K6:
Just the rivetting of stress critical parts gets you into a more specialised area than seems apparent.

In a near equal application of stressed airframe for example, you have to have the correct material spec for the rivetts, the age before use is critical as it's ductility changes with age and if you use it with too much age then you effectively run the risk of stress fracture to rivett the material as you are applying it to fix the parts together with potentially fast and total failure during use.

There is not exactly an excess of them to start with, so any single failure puts you into a very high load on the remaining parts to quickly raise the stress there too.

I have restored my F2 wheels, but I just spent a lot of time internally cleaning with emery paper and a lot of patience. I masked them off neatly for spraying. They don't look to bad. If you do de rivet them you will need a professional rivet gun a blocks, and as mentioned the exact spec for rivets. I don't know the spec but if its aero spec contact Light Aero Spares (google) they may be able to help.  This is part of my job as an aero engineer.  Stick with Plan A, it would be easier. Good luck

K2-K6:
The originals do seem to last well, indicating a good material spec to start with so you ahve to at least match that.

Ever thought about how they get them to run straight without any spoke tweaking to tune them as well?

Thank you to all, what a hell of a response you have all given good sound advise and to be truthful I will as mentioned try plan A first ;) I will take them in to the chap who presently has my frame and associated parts to powder coat and will see if he can clean them up, I will keep you all posted.

I have to be truthful if I had not of posted my question when I did, I proberbly had started to strip them down this weekend :(

Great advise and much appreciated
