CBF250 Centre Stand Fix

Here I'm trying to fix a niggling fault on my CBF250. The centre stand has given problems over a long period. It was prone to jamming then it got loose and wobbly. The stand attaches by a pin through lugs on the frame and a tube on the stand. Water gets in causing rust. This initially caused it to seize and then it got loose as metal was lost.

If you run a bike for a lot of miles in all weathers then this is the type of repair you'll have to do. Remember this bike is used year round and for a good part of that it's saturated in salty water.

The pin

The stand

Frame lugs

The pin is nominally 16mm diameter but has worn

As has the stand (a 17mm dia socket fits in)

The gap in clearly visible

The socket easily fits into the lugs
In the past I spaced it out with bits of beer can but I thought that I could do better. Replacing parts isn't viable - the lugs are part of the frame. My plan is to drill the stand and lugs out to 18mm and make an 18mm pin.

I bought a 18mm diameter drill. I got one with a reduced diameter shank so that it fits into my drill chuck. I also got a length of 18mm stainless steel tubing. Stainless wouldn't corrode and also is quite hard so should resist wear.

The drill bit removes a small amount of metal

New pin
Back together. It's a nice tight fit - wobblyness gone.

Urban Run

Recently we've had some unusual weather. It has been cold but dry and sunny as opposed to the normal cold but wet and dull. It's too cold to go far but there are things of interest nearby. This is a random run through the city generally along the River Clyde.

At the Science Centre I found the paddle streamer Waverley at its winter moorings. The ship was built in 1946 and is the last passenger carrying paddle steamer in the world. The Waverley provides day trips throughout the country during the season and is claimed to be the "most photographed ship in the world".

A Clydeside montage - L to R the Armadillo (auditorium), the Hydro (indoor arena) and the Finnieston crane. 

Fair warning - there will be bridges. This is the railway bridge crossing the Clyde into Central Station. Ok, trains are heavy, but this bridge seems like overkill even by Victorian standards.
The Briggait was, for a century, Glasgow's fish market - now an arts centre.

I've always liked the winged sea horses

The place looks a bit rough. I found this photograph of the building when it was painted. I'm not sure blasting it back to stone was a good idea.

Cambuslang Bridge. This is a strange one. I worked for the Roads Department but never heard of this bridge. It was built in 1892 but at some point was found to be under strength. Weight restrictions were applied and eventually new bridges were built that replaced it. The bridge remained for pedestrians, In 1977 the council built another footbridge beside it presumably because demolition was planned. But it's still here with two adjacent bridges carrying out the same function. The bridge is obviously not being maintained but isn't in bad condition. Left alone it'll eventually rust away and fall into the Clyde. Maybe in 100 years or so.
Rosebank Dye Works. The east end of the city has many derelict industrial buildings but this is special. A fine structure with nice Greek key pattern in contrasting brickwork. It was constructed in 1881 for yarn dying. As far as I can find out it has been empty since 1945 (can that be true?). Cambuslang isn't the most desirable area of the city but surely something could be done with this place.
Cuningar Bridge. This new bridge gives access to a redeveloped area of land. It might look rusty - and it sort of is. This is weathering steel - steel with a small percentage of chromium added. This causes it to form a stable oxide layer that does not require painting. In time this should weather to a dark brown finish. The area was variously reservoirs for the city's water supply, quarries and a landfill site. It has been developed into a parkland. This is a good example of the development of the east end of the city - previously a fairly run down post industrial area.

Reel of Three. This is a sculpture on a roundabout on a recent development in Dalmarnock. It's across the road from my site offices (see below) When I was here this was a derelict factory (Phoenix tube works, I think) It depicts people engaged in a frantic dance.

Dalmarnock Bridge. I spent a year working on this bridge in 1996. The job was to replace the existing steel deck with a new one. Not too difficult but the existing ironwork - everything red in the photograph - had to be removed, refurbished, replaced if necessary and re-erected. Not any easy job, but hey, that's what I was getting paid for.

It might look bright but it was pretty cold.

SV Tank "Repair"

An outstanding issue from my accident back in May is the SV's tank. The bars bent back and dented the tank. I wasn't too bothered about it but, because there was some bare steel, I had to do something before it rusted. 

A possible "cheap and nasty" repair would be to fill the dent and find a nice sticker for the tank. 

Another option I thought about was a complete re-spray. I've never really liked the colour of the bike and, since it's a single colour with no coach lines this would make things easier. I'm not going to do this at present but might in the future.

The damage

I got this set of stickers from eBay. These are associated with the late racer Barry Sheene. I put his No. 7 stickers on the tank and continued the theme with Donald Duck on the back of my helmet.
The stickers were tricky to apply. They don't fit smoothly onto a surface that curves in two directions. I had to put some cuts in the stickers to get a fit.

The SV is currently laid up for the winter. When I post about my adventures next year you'll know why the SV has the tank stickers.

The man himself

White Cart Run - Coda

During my run along the White Cart I was reminded of events from my past. In 1992 I was working on a construction site building the M77 motorway at the point where it crosses the river. 

Here I met Colin MacLeod. You could say we were on opposing sides. He was an anti-roads protestor. For the year it took to complete this section of the road he camped out in the woods engaged in a (mostly) one man protest. He came to prominence when he took to the trees and lived up there for nine days. He was dubbed "The Birdman of Pollok" by the press.

In June he upped the ante. We arrived for work on Monday morning to find Colin perched on top of the 150 foot jib of a crawler crane. The police were called and the crane operator told the cops "I'll lower the jib so you can arrest him". The cops replied that if he fell off and was injured they'd arrest the operator.  

So we waited…..for 6 days. Then Colin came down, was promptly arrested then bailed out by his supporters. The road was completed without much further interruption. I had to admire his dedication to his cause. He died at a young age in 2005.

White Cart Run - Part #2

Anchor Mills. Paisley was known for textiles and this mill was part of world's largest thread producing factory. Now apartments and offices
Paisley Abbey. Established in 1163, but mostly 15th century (I think)

I came across this mural on the cable end of a tenement near the river. It depicts a kingfisher and is dedicated to Alexander Wilson. He was a weaver who emigrated to America in 1794 and became known as the "Father of American Ornathology" 

On the banks of the river is Paisley Town Hall. Typical of the grand public buildings constructed in the Victorian era.

Lift Bridge, Renfrew. Just before the White Cart joins the River Clyde is this lift bridge. It was built in 1924 and is still in operation.
And for the climax of my tour of the White Cart - something really special…..two boulders behind a fence. No, wait, bear with me.

The stone on the left is the Argyll Stone. In 1685 Archibald Campbell, 9th Earl of Argyll led a revolt against King James VI. This failed and he was captured near this spot and subsequently executed. This stone was (possibly) the pediment of a cross near where he was captured.

On the right is a stone known as "St Coval's Chariot". St Conval was a 6th century Irish priest who was carried across the sea to Renfrew on this boulder - like a divinely-powered surfboard, I suppose. He then worked to convert the Picts to Christianity. The stone was (and maybe still is) a place of pilgrimage. The stone has a depression on top (where the leaves are) and pilgrims would drink the rainwater in it to cure their ills. I would have tried this myself but the fence prevented me.


On a very wet and dull day I'm in Clydebank looking across the River Clyde to where the Cart joins it.  

I hope you enjoyed my run across the grey old city. As always I was aware of how much is packed into a small distance in this country and that even though it's cool, wet & dull a run on the bike can be enjoyable.

I didn't want to end the tour on a bum note so today I went back to Clydebank when it was sunny.

White Cart Run - Part #1

It's an idea of mine to follow the course of a river and see that I can find. I've posted a few such runs. But it's cold, dull and wet so I'm reluctant to go too far. The White Cart is a short river that rises in the hills near me and wanders across the south side of Glasgow for about 20 miles before joining the River Clyde. There can't be much of interest in that. Can there? Well let's see.

This is near my house and I've featured it before (where I incorrectly said it's on the Cart) It's an old mill outside Eaglesham. It's on Polnoon Water, a tributary of the White Cart.

This was built as a cotton spinning mill in the late 18th century. The stream has been dammed to provide power for the mill. It was nicely converted into apartments and I found an old photograph from 1965 before conversion. The website says that the photo can't be put on-line but I suppose a link is ok.

The ford at Eaglesham. I often pass this on my travels. The depth gauges are a recent addition - it seems that the metric system has not yet been adopted in East Renfrewshire.

The Footbridge in Linn Park. Only a few miles from my home and I'd never been here. As someone who toiled in the bridge building industry this is a little gem. It's an early example of a cast iron bridge dating from the early 1800s. Cast iron was replaced by wrought iron then steel but because it's cast rather than rolled it means that complex shapes are possible. Also cast iron is less affected by corrosion than steel so this bridge, built at the time of the Battle of Waterloo, is still in good condition and with a little maintenance it should effectively last forever. 

Snuff Mill. Again, close to where I live but I can't remember being here. The (former) mill is on the left behind the bridge and milled snuff (amounts other things)
Sitting in a fine location on the bank of the river is Pollok House. Once a private house and estate it is now public.
Footbridge at Ross Hall Academy. In the distant past I earned a crust designing and detailing reinforced concrete so I appreciate the single, elegant form of this bridge.
Autumn scenery at Crookston Road

Crookston Castle. Again I've passed this many times but never been bothered to visit it. It's in good condition for something built around 1400. It's in a pleasant woodland setting in well maintained grounds. Part of the castle is missing but, given its history, it's lucky that there's anything here at all. In 1489 the Earl of Lennox revolted against the new king James IV. The king laid siege to the castle and used a formidable weapon to end the rebellion. Mons Meg was a huge siege cannon that fired a 20" diameter, 385 pound stone canon balls. After a few of these hit the castle the defenders gave up.
