Re: 1962 BSA DBD34 Gold Star barn find restoration
I finally found a couple of hours free time, so I laced my front and rear hubs.
The front 190mm brake took quite a while to lace while the rear quick detach hub was dead simple and quick.
The front hub:
The Buchanan spoke kit consisted of 40 spokes, 20 interior and 20 exterior spokes. The BSA factory parts manual shows the same part number 42-5552 for all 40 spokes. Each nipple was lubricated inside and where it meets the rim to prevent future galling. This is an alloy Excel WM2 19" flanged (shouldered) rim.
The interior spokes (end showing to the outside) are obtuse and the exterior spokes (ends to the inside) are 90 degrees.
(top) exterior spoke 90 degrees
(bottom) interior spoke obtuse angle
Buchanan Spoke and Rim marked the rim making it easy to identify the right and left side of the front rim.
The interior spokes went in first on the right hand (brake plate) side with the spokes pointing forward in the direction of travel as per original. Everything was placed on a large piece of foam to protect the paint and rim.
I flipped the wheel and laced the left hand side (drum side) interior spoke going the opposite (towards the rear) direction.
Next were the exterior spokes on the left side. They were a tight fit and it was necessary to remove the drum ring from its plate in order to get the spokes in. The angle was difficult and I need to use a punch in order to get the spokes to sit in their seats. The right hand exterior spokes went in easier. I left all the spokes loosely laced .
The rear hub.
Chomp.
The BSA rear quick detach hub has 40 identical straight spokes and could not be easier to lace. I did one side and the other, following photographs of my original wheel. This is an alloy Excel WM3 19" flanged (shouldered) rim.
Done.
I am going to mock the wheels up on my frame this weekend so I can determine my offsets and then true my wheels. DO NOT FORGET to measure the offsets of your original wheels like I did!
