I would like to make a one piece mould (less work) of the front of my Elan so I can make a one piece flip front. The bonnet will be fitted and blended in prior to making the mould. I can't see any locks. The mould should flex around the wheel arch lips. Can anyone see any problems?

Lucky for you, the Westfield grp quality is way beyond what lotus did those days. So your weight saving will be greater than mine. I managed to get the body down to 20kg. Original is about 40-45kg. Bonnet alone was 14kg and is now 3,8kg (near the bottom, you have to keep higher thicknesses against road dirt, so the weight saving of the other parts are lower). I would have been able to get to 3kg, but not with 245g cloth skin, and not within the budged. You don't know 4-5 guys who would invest in a full elan cf conversion?
This would be the project, I was dreaming of since I remember dreaming of anything. I would take one for myself.

Yeah, the fibreglass is over 1/2" thick in places!  Too many Elan owners are purists so the thought of doing what I am doing is almost a hanging offence to them.  The only fibreglass left on the Elan once I change the front clam and inner wings will be the sills, front and rear scuttles and rear wings. Floors, dash, all interior panels, bulkheads, boot lid and floor, rear wheel tubs, rear light panel and roof are all carbon. Doors will be soon. Boot went from 6 to just over 1kg!

A few years ago Nick from Carbon Weezle was going to make me a body and I bought the carbon for it. Unfortunately circumstances have now precluded this from happening so I am doing it piecemeal :-)
