A blow by blow account of rebuilding my 1961 Velocette Venom and my struggles with the world of motorbikes in general.

Putting the cart behind the horse


I had to get organised.  I was looking at the increasingly messy workbench and thinking that I could see no end to the tunnel into which I have gone, so I had to plan.  Perhaps this yearning is as a result of all those years working in engineering. As a callow youth I would have happily gone into the garage and done the first thing that came to hand or that grabbed my attention.  This would be why my Tribsa, my Hondumph and my Gruch (Greevse/Puch – made from other peoples chuck outs) came out so odd (don’t ask!).

So what have I done?  Firstly I’ve contacted Grove classic motorcycles and got a copy of their excellent catalogue. 


This has all sorts of exploded diagrams with Velocette part numbers against them and is worth its weight in gold.  Next I joined the (mightily efficient) Velocette Owners Club


The club also has a spares scheme that works on the same system and so the same diagrams work.  Incidentally, these are the same as used in the Haynes manual.  Then the long boring bit – I wrote up spreadsheets for the engine internals and casings.   In these I have left columns to organise the work. 



So now I know what areas to work on and where to get the bits.  The final part of the puzzle is in knowing what the priorities are.  Mostly, I’m ok with engines, but there are areas that I need to consult people with knowledge of specific areas of this vintage one.  Luckily, there is a superb technical resource in the Velocette club and its technical forum.


A good example is to decide if I have to change the valve seats in the head in order to run unleaded petrol.  I put up my question and within a day had a host of very practical and well considered answers all with the same consensus of opinion.  Happily, I don’t.   I am changing the valves though since the stems were so badly scored, but I’m holding back until they arrive to check the clearances in the guides before changing them too.  

This has been a definite step in the right direction.  In fact I was so pleased with myself I spent an hour or two cleaning more parts and checking what I’ve got against my new lists.  Just like at work, there’s only so much desk flying that I can stand!

My Forgotten Past Double Life as Dr Bodgeit and Mr Scarper


They say that we store everything we experience in our memories, but that the access to most of it is often only triggered by key sensations.  I believe this is true because as I started cleaning the pressed steel transmission parts my rose tinted spectacles fell off my face and shattered on the floor. 
My alter ego as Dr Bodgeit had been hard at work back in the 1980’s - just look at the backs of the studs on the inside of primary chain case:
 
If you spotted the solder trying to hold those clinch studs in place then give yourself a coconut.  If you missed it, then here they are again:

Lovely monstrous carbuncles and as I recall for the first time in what seems like aeons, bloody hard work as at the time I’d lost my Dad's tin of flux .

The drive sprocket cover also came with a torrent of long forgotten emotion.  Back in 1979 I had to do a quick fix to a cracked mounting bracket or miss the band playing on the old Pier.  Time was short as was my patience (Mr Scarper) …

…yes, that’s a Meccano nut and Screw!  I remember riding along thinking “Well, it’s still holding” in answer to my conscience long after the bodge had been committed.  Incidentally, the gig was cancelled when I got there because the band said the pier was unsafe that it about to fall down, which, with hindsight, was rather ironic.  

Another cringe worthy bodge is the rocker cover.  Back in the day, I read somewhere that it’s a good idea to add a breather to the rocker box as this can prevent leaks, so I drilled a hole in the beautifully shaped rocker cover (why there?  I can’t remember now).   I drilled it too low and it dribbled oil as soon as the engine was started, so I plugged it with any old nut and screw and did it again…



…real class, but I’ve left the best to last.  

Andy’s found the rocker box oil feed pipe.  See the nut.  See the split.  Remember the plonker clamping it up with a jubilee clip hoping it would seal.  It did for a bit and then my right boot became more waterproof than my left.










There are those in education that say we should take care not to stifle creativity in the young as was done in the bad old days.  Looking at these I can’t see that dull lessons, bad food and ritual corporal punishment administered through a twisted system of justice caused me to lack creativity back then.  From what I’m starting to find, I could be resourceful and creative in a sort of shootingfromthehipasthemomentdemandsitand nevermindtheconcequences style.   A true Brit!
