Mr CND

It is with great sadness that I have just found out that my friend and engineering mentor Bruce Hazelgrove died of a heart attack. Bruce was an engineering talent the likes of which I haven’t seen before, he could design, draw, work out gear loadings, scrape white metal bearings, machine and weld. He had incredibly dexterity and could literally turn his hand to anything. He was the brains behind the Battlemax project and the CND Laverdas that you may know of plus lots of design fabrication for the car racing world. More recently he was featured in British classic bike magazines for recreating obsolete engine parts and crank cases.
We shared a workshop for a while and were good mates . Top bloke and very smart guy.
 
So sorry to hear..
The CND850 was a very special creation that fascinated me from the very first time I saw it. I had the machine under my wings for several years and I was amazed by the incredible eye for detail. Photos couldn’t do it justice, only in the flesh it shows what a true marvel it is.
Those silencers were a work of art and when I removed them for the first time I expected them to be heavy lumps, but they were feather light! The tank was beautifully made and extremely light too. I could thoroughly enjoy looking at the front mudguard which has an exquisite shape.
The engine was such a violent shaker that I feared that on the long run, most of those beautiful components would suffer, crack, or worse. I did several attempts to improve it, to little or no avail. It was more a show bike than a riders bike and so I decided to let it go.

It was a privilege to have owned it though. If there is a Cloud Nine, I bet Bruce Hazelgrove can be found there.

Ironically Bruce didn’t build the engine. The only pic I took back in the workshop shows Bruce with a Honda Hawk engine in one of his frames- box alloy from beaten sheet, incredibly light. Billet yokes and swing arm pivot are all in house. His own V twin engine being just out of shot, typical but I think I was using up the end of the film!

Obviously a very talented guy to be building his own frames. Sadly we are losing a lot of the individuals who not only built bikes but knew what they were doing not to be replaced.
The CND looks amazing, a bit like the mid 70’s MV350 👍

Did you go as deep as balance factor in trying to improve it, Marnix? If the engine ran similar balance specs to an SFC pr an SF then the only conclusion would seem to be that the frame is too light.
