Special Hints

[NickGoodwin]

I have scanned an article from Newnes Motor Cycle Repair and Upkeep (looks like it’s just pre-war)… and to be honest I’m not sure whether it promotes best engineering practice … there’s some evidence of the use of big lumpy hammers!… so here’s the first 3 pages. If people say ‘oh no, not that old article… it’s all completely wrong’ I won’t put up any more. If the rest of the article is wanted I will upload the remaining pages. NB. I am a complete newbie so can’t judge the correctness of advice given in the article.

Hi Nick,
Don’t worry about lump hammers.I use a lump hammer and aluminium bar to separate crankshafts and a lump hammer together with a sledge hammer as a dolly to knock up cranks. Sounds brutal but is the way to go if used properly.

Hi Nick,
Have you looked at www. scotttechnicalities.com.au and http://www.mossengineering.co.uk

Hi all,

I think the Newnes “Motor Cycle Repair and Upkeep” booklets were published around 1931-1932. They were sold in 14 weekly parts for one shilling each. Many years ago an elderly friend gave me his 14 volume set and told me that everything I needed to know about vintage motorcycle maintenance was there – and they remain a great source of generally very reliable advice and guidance.

BUT the chapter on Scott engines does need a caveat. Last night I saw Glyn Chambers at our Christmas party and he handed me a note which I promised I would post on the website. It reads:

You need to use a big hammer to knock cranks apart or together – however if you do it as the book shows you stand a very good chance of smashing a c/case cup. Get someone to hold and take the weight on the flywheel as you bash the centre bolt head. When “knocking up”, support the weight on the opposite crank. 3 hard blows are enough.

Merry Christmas!
Martin

Thanks for the replies Bob and Martin… very interesting.

Thanks for posting those, Nick. I’ll print them off but make sure I annotate the appropriate page with Glynn’s caveat 🙂
