Eddie, I personally would have kept the Mounting-ring, it is sturdier and better for the engine case. It helps to dissipate torque loads.

That's what I was thinking but wondered about the weight. But that is probably negligible?

The flywheel needs to be removed. In the original convertion of the engine, the flywheel hub is cut out and the rest discarded as the 'plane is prop started. I want to fit a starter so need to remove the weight of the flywheel but still retain the ring gear. Imposible to find an auto flex plate so I came up with this:

VW flywheel cut to pieces. Ring gear cut off and hub cut out. The original weighed about 10 pounds. The idea is to make the web out of 7075 as per the drawing. The thinnest I could get was 10mm. Hope it won't be too heavy.

The power plant to be. VW type 1 2.1l conversion. Will have to get my butt into gear with the mould for the engine cowl (and the cowl)

Fitted the wings yesterday with the real struts and made the jury struts which must made up with the wings fitted. I planned to make the plug for the engine cowl mould today if the weather was good as I have to work outside due to space constraints.

So with the rainy weather...... :( .... but my lack of patience got the better of me and I got both. The rain and an engine cowl plug :mrgreen: Took me an hour to get the garage clean though #-o #-o Still a lot of work to get the final plug out of that ball of foam.Nobody told me I will need sculpting skills when I started with this :? Looks like the VP nosedived into a block of dough :shock:

A bit of sanding, two glasses of a nice red, a few hours and a moerse mess later, it looks like there is actually an engine cowl stuck away somewhere in that block of foam 8) .....Still a lot of work ahead though 8-[ 8-[

Hi, hoping for a bit of advice. I have just re-assembled an evans vp1 that I bought last year, it supposedly had a zero timed 1800 vw engine, but after firing it up for the second time both of the cylinder heads have cracked around the bolts and seem to be beyond repair, perhaps over tightened, any idea where to start looking for replacements??? It is duel ignition running off two lucas SR4 mags if that makes any difference, Cheers.

Good evening shirewood. I've got no idea where you will get that in Britain.

Maybe try the VW Yahoo group?

Thanks for the replies, I have found some with single ignition and will hopefully get the second holes machined, cheers.
