Or just click on "Additional Options" below the message box then select Attach: Choose File and locate the pic(s) on your computer.
I'm only old on the outside.

Arthur, here's while waiting for you to manage to post your pictures...
You have my sympathy, it took me a while too.

This the first layout when I started making my patterns.
There progressing slowly as I get the bits to measure, but not easy to find the parts to do it from.  I've bought a few bits such as cranks, pistons, cam shafts but still lots to get measurements from.http://s1285.beta.photobucket.com/user/arthurlewthwaite/library/G50%20Project

Mr Lewthwaite ,
                          Is this just an interesting engineering exercise ? , what do you intend to do with it when finished , it is truly a monumental task .
Remember you and all men are standing on the shoulders of giants

Arthur.

Do you have a chassis or are you only interested in the engine?

Your patterns don't look far off, just a bit of prettying and some Resolan.
I wouldn't worry to much about you draft angles etc nor making relief this can all be done in the sand when you start moulding up. When moulding you can also "knock in" some shrinkage.

How are you running your rods Forked (Harley) or parallel Ducati?

this project is moving slowly at present due to other commitments and projects,am making some paddock starters and anew project to make a contra rotating blades helicopter that is controlled just like steering a car,with a steering wheel .the idea being to build small personal helicopters that are easy to fly,if i can get one built and passed by the civil air craft authority,the crmc could hold helicopter races,haha,

have widened crankcases by 30mm and obtained moto guzzi crankshaft and rods and bearing housing with main bearings,this is one piece crank with same stroke as the  g50 matchless ,extra width allows more room for front cylinder carb and rear cylinder exhaust .main bearings hall metal not roller bearings,new half timing pinion gear made to fit crank,crank modified to do job.allows for a belt drive pulley to be fitted where guzzi clutch flywheel bolted on.slowly getting there.
