I've followed this thread with interest - I'm working on a 5A with reversing gear at the moment, and if I've got it right the eccentrics foul the step in the crankshaft. On nominal dimensions the eccentrics will rub on the flange of the crank bearing, but the crank change in diameter is a further 1/16" out. The additional drawing for the reversing gear shows a clearance of about 1/16" between the eccentrics and the bearing flange. (My drawings are dated 1954 and issued in 1965 - the engine was started by my grandfather who died in 1966 and I feel it is about time it was finished!)

I have an Automobile Engineer's Reference Book from 1956 which gives the taper as 3-1/2" per foot on dia, or 1 in 3.43, or 16° 35' 41" included angle. So I guess your 8° per side is close enough!

Trespa offcuts are available from David Meddings DeSign (or they used to be when he had the unit next door to my work - he has now moved further up the industrial estate so I don't see the piles of material any more). I don't have a contact number handy but I am sure you can find him on Google - he also used to trade as Reel Furniture. He is in Attleborough, Norfolk

I've had a quick look through some books on marine steam engines and I can't find any that show a flywheel, but they all appear to have a flange as Jason suggested. I doubt if you would get keyways on the bigger stuff.

Pages are in reverse order, but hopefully still useful

I have the issue you want. I will scan it for you

Mine arrived yesterday, so there is probably still time before it can be considered lost.

My experience of ME mags that don't arrive is that they say they don't have any spares left to send out and they extend your subscription by 1 issue. Then you find that the company that takes all the surplus ones will sell you one but you have to pay the postage. It's a bit of a con! You would have thought they should get a copy back from the surplus company, or at least arranged for that company to supply one FOC

I also use Metalfast (or ThyssenKrupp as they are now known) but have recently started using Shropshire Stainless & Aluminium www.ssaltd.net . Not sure whether they will deal without an account, but they are very keenly priced on sawn plate.
