A Frame is Born
Here you can follow the creation of a DAVE YATES custom frame. If you wish to see more
detail simply click on any of the images to view an enlargement.
|
Every custom frame starts with a
consultation with the customer. Dave has a fully adjustable jig that can be used although
he prefers to work from the riders existing bike as a starting point for the design. |

Tubes and components are stocked in a variety
of types and sizes.
|
|
The tubeset and components are selected using the
customers order form. |
| The building of the frame commences with a set of
sub-assemblies. This is the chain stay/drop out joint using a jig to position the joint
for brazing. |
 |
|
This is the seat tube/bottom bracket joint being
brazed using the main jig. |

Here you see the forks being brazed

The sub-assemblies are carefully assembled in the frame jig
which is designed to allow any size or type of frame to be built.
The bottom bracket is the fixed reference and all the other
centre lines are adjustable. Co-ordinates are used to set the seat angle and rear drop out
centres.
The measurements are taken from the customers order form and
are checked and re-checked several times. Once Dave is satisfied the dimensions are
correct the joints are fluxed and the triangle brazed together.
|

|
 |
The seat stays are fitted as a second operation. They are carefully marked to length and
whatever end treatment the customer has specified is applied to the tops. Then they are
brazed in place. |

|
The "braze ons" are silver soldered in
place and the whole job cleaned up by careful use of files, emery cloth, elbow grease and
a great deal of skill. |

|

|
 |
|
Once the metalworking is finished the alignment of the frame is
checked, and any minor imperfections corrected.
|
 |
The frame is then shot blasted all over before
its trip to the paint shop.
|
| Within minutes of the shot blasting operation the
frame is sprayed with a coat of acid etch primer that provides a secure base for the paint
system. |
|
|
Several coats of colour, depending on the colour
scheme, are applied building up the thickness to provide a tough durable coating after
stoving in the oven. |
 |
Once the paint has been stoved the transfers and
any lining required are applied and a coat of clear lacquer is sprayed on to seal it all. |
 |

|
Before the job
leaves the workshop all the threads are tapped for easy assembly of the bike. |
And Finally......... the finished bike
ready to be ridden off into the sunset !!
