Stainless isn't always magnetic

Stainless isn't always magnetic

  yes agree, but put a provision of "binary" split in assessment.

From contemporary knowledge, I don't "think" there were stainless construction offered in production wheels. Could be wrong though 

The 750 f2 were steel and satin chrome with many others aluminium alloy convex or inverted design. Unsure of 125T, CX 500, CB 650 etc.

There may have been stainless spoke arrangement on racer RCB that I think was first use of this generic design in 1976.

True DomP, I've also not eliminated plastic.😄😄😀

I thought stainless was rarely magnetic, unless cheepo stuff

There is an entry on Wiki as well.

Properties can shift according to alloying mix and the attributes those bring.

"Types of stainless steel
Stainless steel comes in over 57 types of standard alloy, as well as numerous custom alloys produced by stainless steel manufacturers. The composition of each type varies. Based on their metallurgical properties and microstructures, stainless steels can be divided into five categories:

Austenitic Stainless Steels
Ferritic Stainless Steels
Martensitic Stainless Steels
Duplex Stainless Steels
Precipitation-hardened Steels
The Duplex stainless steel combines austenitic and ferritic crystals, so it offers the best of both worlds and is magnetic whilst also having generally greater corrosion resistance than the austenitic 304 and 316 stainless steels."

Quoted from here https://www.eclipsemagnetics.com/resources/guides/are-all-stainless-steels-magnetic/ some are more condusive to welding, while work hardening etc also varies.

With the milder spell I have started to assemble some of the frame bits over the last few of days, center stand is in place.
Steering shaft outer races fitted to steering column, painted the front steering shaft ready for fitting bottom race and fitting the column. A taper roller kit that was cheaper than the standard ball bearing races, old bearings were well rusted. (JMT Kit was from M&P on offer at £10.18)

The kit came with a bottom spacer, I will be fitting an improved bottom seal that is attached to a thin spacer rather than the rubber original type. I have a selection of thinner bottom spacers that I can use left over from my 400 build.They are steel JCB bucket shims in various thicknesses that are the correct i/d & o/d. My bearing puller tool will remove a bottom race undamaged if I need to change the spacer under the bottom bearing.

Not much of an update really as cold spell with no warm house to retreat into has slowed down progress.
Frame is on the bike stand, hit a snag with my fix for the worn frame hole for the center stand, not a big snag but enough for some cogitating to occur. When the center stand is used the return spring pushes the stand boss towards the olive that I made. 

I have a cunning plan Lord Black Adder.

#Frame after powder coating by Macabe Thiele, on Flickr

[McCabe-Thiele (Ted)]

The brake lever/pivot sleeve is somewhat sloppy due to wear, both the lever & the insert are NLA.
Hard to work out which part has the most wear, the collar or the insert

What is the way forwards to fix this sort of problem?
Presumably members working on rarer model Hondas  come up against this problem.

[Bryanj]

Probably a brass bush turned to fit the worn shaft and the hole for the insert

[McCabe-Thiele (Ted)]

When I dismantled the center stand I found that the centre pivot shaft was broken quite close to the brake pedal bracket that bolts into the end of the shaft. Clearly this damage had been present for a long time leading to wear in the frame at the left side as the shaft was pretty free to wobble about.

The original stand shaft looks as thought the end part is pressed into the shaft as it was serated at the end, this has kept it in place for many years.
When the brake was applied the whole bracket was moving as the end bolt was finger tight, this might explain why the wear is mainly on the left side  of the brake lever, the outer end has relatively little play.

Reversing the insert does not significantly change the amount of play, the brake pedal though has some serious wear to the inner left side. There is not a lot of material to cut into to make it good with an oversize bush/insert.

I'm going to start fitting the steering shaft whilst I mull over my options, I'm still working on the footrest hangar plates, I have a couple of spare sets that came with the bike to practice on. I'm thinkng a Matt finish might be more practical, still needs the preparation work.

You are a star Ken, I must have a poor search engine!

At first I thought I had made a Typo claiming to be related to one of the Kray Twins, I'm a Pussycat really not hard at all.lol

[McCabe-Thiele (Ted)]

I've had a good couple of hours on the SD this afternoon, the headstock taper roller kit I bought fitted a treat, just did away with the thick base spacer, I fitted a thinner one I had in my box of bits.

Trouble is when something goes well I'm looking for a knock on problem.

🤭 yes I’ve had that feeling Ted when things are going well, your looking over you shoulder so to speak! 😂 in my case it’s not being pessimistic it’s being realistic! 🤭
