Its all about bikes

Donated Bikes
So far this year we have had 2 folding bikes, A Lenton Sport from the 1950's, a Raleigh Supreme, another Raleigh gents bike from the 1970s, a good BMX, a shaft drive bike, a Trek and a Bob Jackson.  Not to mention other assorted items and spares.  Unfortunately the Lenton Sport has a serious crack at the bottom of the seat tube which is a shame as its probably 531.  The Bob Jackson is in excellent condition frame and paint work and is 531c.  Here's a picture

This is a beauty but presents a problem, what do you do with it? Rebuilding as originally specified with 14 speed would not make a desirable bike.  Putting a triple speed chain ring at the front is OK but this frame begs for something special.  A single speed or fixie is possible but for a good job would cost around £150  to £200 in parts if the wheels are included.  This makes the final price £300+ and a limited market.

It may be better to sell the frame and with the money buy a new stand.  What a choice.

Service
It's heartening to have had a number of people through the door wanting  their bikes serviced.  The cold weather and snow takes its toll on chains and sprockets.  The dark morning means that there is little day light time for bike maintenance.  There have been one or two bikes with chains that can flex a full circle.  We are busy and I hope it will stay that way. 

The Meditation of Wheel Building

About a year ago I started building bicycle wheels seriously as part of the Spindles project.  I had built a wheel about 3 years ago for my own bike which was a very unsatisfactory process as I didn't have the correct length spokes and so had to cut my existing spokes to length.   Since last year I've probably build about 16 wheels and so become somewhat more than a novice.  I found that there are three very important aspects to wheel building: getting the right length spokes, gradually increasing the tension and awareness.

The right length spokes.

I have used a number of the web based spoke length calculators but the best one for me is Sapim as its very clear as to what should be measured and seems to give the right answer.  I don't like the calculators where there is a drop down list of hubs or rims as the one I want is usually not there.  I can use a vernier calliper (at least an electronic one) and have a steel 650mm rule to get the measurements required by the site.  I've used DT spokes but have also started using Alpina plain gauge stainless steel as they come in boxes of 144 for about £20.  I have a box of blue nipples that provides a single marker spoke for each wheel that I'm building this year.  This is a trick I picked up from reading 'Its all about the bike' by Robert Penn.

Increasing the Tension 

Many words have been written about the number of turns to apply when threading nipples onto spokes during the lacing process.  I have found that to start, just screw the nipple up with fingers so that it's edge is just hiding the end of the thread is sufficient.  When lacing the alternate direction spokes, if there is tension building in the wheel then slacken off the other spokes with a couple of turns.  The aim is to have almost no tension in the spokes after it has been laced but all the nipples are at the same number of turns (assuming the rim is new and round).  Hopefully this gets the radial position even and no 'judder' up or down as well as lateral evenness.  At this point start to evenly increase the tension on each of the spokes using the 'key' spoke as a guide.  The best spoke keys are produced by Park.

Awareness  

The most important aspect of wheel building is being focused on what is happening.  Don't try to lace too quickly as mistakes are time consuming to rectify.  Go at a pace that allows the mind's attention to easily follow.  Don't listen to music or get distracted, just stay with the building of the wheel.   Focusing the mind is the most difficult thing but can also be the most rewarding.  Building wheels is almost a meditation practice: as the tension in the spokes is slowly built in the wheels so the tensions in the mind are released.  Before you know it the wheel is built.

Spindles in 2011

Saturday the 8th Januay is our first open day at the Pound Arts Centre in Corsham.  We have a number of new road and mountain bikes that are close to completion as well as the Cargo Carrier Bike that a friend in Biddeston is currently constructing.

On the agenda for 2011

We hope to do a newsletter for Katherine Park that will identify safe cycle routes into Corsham town.

Start a Wheel Building Service.

Promote the project in local magazines.

Find things to do with old tyres and inner tubes.

Cargo Bike

This Cargo bike was make locally and provides a very useful combination of bike and carrier.

The maker it currently designing a Cargo bike for Spindles that is capable of transporting bikes as well as   carrying advertising. 

wheelchair bike for community use

The wheelchair bike 

This wheelchair bike was locally made for a person with MS who is now too ill to use it.  It 's a clever design integrating bits from several mountain bike as well as a wheel chair.  If you know anybody who who have a use for it then get in touch using our email address.

This bike started life as a frame that was obtained locally.  It's a standard 23" frame that probably dates from the 70s or may be the 60s but is nothing special.  The paintwork was poor and some touch up has been attempted in the past however there was little rust.  It hung around literally for about 6 months until I decided to turn it into a single speed.  It was painted with black hammerite and the lugs were highlighted in white.  This is primarily to preserve the frame but provides a pleasing effect.

Here's the finished bike on sale for £180

Single Speed - light 24" frame

A 24" frame Single Speed/Fixed speed. SOLD

This bike has an unknown origin as I originally came as a standard geared bike.  The frame is made of thin steel tubing - may be Reynolds - that has very neat fillet brazing.  The rear dropout is 120mm and the bottom bracket is threadless that suggests a track frame.  However there are braze-ons to support front and rear gears.  There is one small dent in the left seat stay.  The paintwork is scuffed in places.  The single speed configuration seems to work best and the whole bike weighs around 21lbs and is a joy to ride with the extra narrow 27x1x1/8 ulta sport tyres.


The buyer suggests that its a 1970s Viscount with Chromo moly tubing see sheldon brown's page on this

1940s Raleigh Ladies Bike with Brooks B66 Saddle

An Original Raleigh Ladies 21" 3 speed Roadster possibly from 1940s SOLD

This was in poor condition when we got it, but was complete apart from the saddle.  see Raleigh Renovation The previous owner claimed that it was 1940s.  It has interesting cable brakes that may be from around that time however I do not believe the handle bars are original.  The front axle has been replaced along with the cables.  The frame has been pained with Hamerite to preserve.
There is a 3 speed Sturmey Archer operated by a modern lever.  The lovely original was not in working order so had to be changed.  The gears work but are not 100% as positive as a new 3 speed would be.  Vintage back rack is included.

The bike is now sold
