Brilliant work! The Engine is Pure Artwork! Even with the cover one will be able to see just enough to be gobsmacked

Well the intimidating engine covers put up a bit of a fight, I don't think I can claim a victory but possibly a forced down out of control.
The top cover needed to be bent to a constant width along the bottom. I spent many hours playing with paper templates before I had a real eureka moment. I just cut and annealed a piece of sheet aluminium to the right length, 15mm wide tapering down to 13mm. With the centre line marked I started the bend over a pencil and finished it in my proxxon vice which has a nice ledge in each jaw I could get a flat base from.

4 hours thinking, head scratching and experimenting time, 5 minutes making time!

The 4 separate covers on each were infuriating and needed careful measuring, test fitting and fettling. When it came time to glue them in place it all went a bit pear shaped but I wrestled them onto the model. The two copper exhaust at the front of the engine are 1mm copper tube.

You can still see as much of the engine as I wanted visible, not very much!

Not the neatest work I've ever done but there will be a big exhaust pipe directly in front of the cylinder tops so I'm not too bothered.
I was thinking there is only one more big hurdle. The making of the wings, I'm going to have to completely clear my bench before starting them. I seem to have made rather a mess, I'm not sure which is bigger hurdle!
