Honda CB400NA Superdream - new money puddle.

[K2-K6]

Probably the simplest way to recover it would be to get a plate made (bespoke washer really) in something like 4mm plate, four holes drilled into that and just placed correctly! then with welding through the holes to frame structure to secure. 

Holes  unless you know someone with a spot welder, local bodyshop etc ? that may do it as adhoc job for you.

That'll give an easy install and competent bearing surface in bore to repair it.

I've resurrected my Brass olive, if I can sand it down a tad more it might work

[McCabe-Thiele (Ted)]

The Brass olive is an interference fit on the shaft when I push the shaft fully home from the other end, on assembly I will pop some Loctite on the outer edge of the olive and shaft contact.

It has been suggested elsewhere that Brass might be too soft due to the weight of the bike.
As it's a tight fit with the shaft being double held at the other end by the usual clamp plus a bracket bolted to the center of the pivot to stop it rotating it might be good for a few years.

I think thats a great fix Ted, worth telling the other forum

[McCabe-Thiele (Ted)]

I've posted a picture on the Real SD Forum Bryan, only comment to date was that brass is a bit soft, suggesting the weight of the bike might be an issue. I'm happy to monitor the situation and see how it works out.

For what it does i think it will be fine mate

Weren’t the bushes in the CB900FZ plastic?

Softer than brass.

Whilst I'm thinking about what to do with the slightly pimply fork sliders I decided to spend around an hour on one of the fork stanchions, I think it's the left side iirc.

I started with Ken's little plastic wheels Red (220) then light green (1000) then 5 minutes with some medium soap on the buffing wheel. I'm chuffed with the improvement, I will do more until I am happy with the finish.. I used my Dremel type tool instead of a cordless drill at speed setting 3.

That looks pretty shiny!

I tend to paint mine, as I lack the patience, buffing wheel, and take the easy way out.
I have to re-do the fork lowers on the daily ride, and wish I had them looking like that!

That looks great Ted. Those whizz wheels (as I call them) and reccomended by Ken really are the bees knees.
I will use your method when it comes to polishing the TL125.

[McCabe-Thiele (Ted)]

After mixed results plus daft rising costs/quotations from two local firms I have used previously a mate put me in touch with a small firm near Chesterfield. They specialise in vehicle paintwork they also do powder coating.

As the Superdream is never going to have much end value I have taken a risk and taken the frame to them. I will report back on what sort of job they make of it and name the place when I have the frame back, hopefully by the end of next week.

Photos will be posted, I'm using the firm based on recommendation from someone whose opinion I value.

Ted - what are the plastic / polishing wheels you referred to?

[Skoti]

Don't know what Ted used, but I got a similar result using a scotchbrite pad type version of a polishing disc from Lidl.

Not too brutal but enough to easily remove the lacquer and gently polish up alloy.

Then finished by hand with solvol autosol.
And finally done with autoglym super resin to seal the elements out.


EDIT.
Parkside fibre disc set, item number PWSZSP1.

I notice Ken has previously posted a review on these and if they are good enough for Ken they were good enough for me. They are are great product.

Ted - what are the plastic / polishing wheels you referred to?

I use two of the polishing discs on the same shaft, although they come in a range of coarseness I tend to use the 220 grit equivalent ones for the first phase, then the 1000 grit. One pair of wheels lasts for ages as long as you do not apply too much pressure or have your dremel type tool set too fast. The plastic discs are directional, it takes a bit of practice as you need the wheels ideally to be at 90 deg to the metal. I used a cordless drill back in 2020, a dremel type tool is much better, mine is a mains powered Von Hous recommended by a member. Final phase is the buffing wheel using the different grades of finishing soap.
Ken has discovered a new super grade of finishing soap that he was telling me about last week - it's Gold and priced accordingly.

These are the ones Ken uses & recommends, I think they are mentioned in Tricks & Tips here http://www.sohc.co.uk/index.php/topic,28743.0.html
