Removing powder coating from wishbones and playing with pedals

63 + 4  = 67hrs

Two weekends worth of worth here….

Last weekend I spend a couple of hours removing as much as i could of the powdercoating from the wishbones to get them prepped for pressign the bushes.

I started this with a high grit sanding wheel on a dremel, this did a reasonable job,  but wasnt quick work – maybe 10 minutes a bushing hole.

I then tried to work by hand with varying degrees of sandpaper/wet and dry.

Then i tried to fabricate something with a mains drill and sandpaper on a drill bit plus padding.

In the end i resorted back to the dremel – I didnt end up removing every dot of black powercoating – but did remove 95% from each bushing housing, I was conscious i didnt want to take too much material off and bugger the fit of the bushing – read an interesting thread on WSCC around different bush types, i guess nylon would be good, but im going to stick to metalistic for the time being – lets not run before we walk.

I did look at pushing the bushes into the housings using a reasonable size bench vice but they either went in not straight or they didnt budge.

Tips i;ve subsequently learnt are using washing up liquid to lubrricate the movement, and freezing the bushes to try and make them that bit smaller – not sure how much of a falacy that is in reality – can;t see steel shrinking that much at a few degrees – but what do i know!

After nearly screwing up a couple of housings I have opted to get someone with a press to do it, called Tower Garage Marlow and they were really helpful and are going to do it for me – hopefully a good job, we’ll see.

Todays  weekend found me sitting in the car and finding with shoes i was struggling to get to the brake pedal easily with the steering column mount being a tad in the way, in the absense of being able to move this (welded to the frame) I spent some time looking at the pedals – I’ve subsequently moved them (in) towards the master cylinders by a couple of threads on the rods, did this by chopping about 5mm of the rod and re threading (and using yet another split pin 🙂

End result is the brake and cluth pedal don’t line up 100% now, they are about 5mm out of line -who will notice this please!?

However as a result both pedals are now a little better positioned – for me that is….
