Hey Neil,

Took a look at your model tonight. Getting better...but few issues as you'll see in the attached pix...which stem from the "basics".

- Alignment of curves/surfaces are still off.
- Not sure how you built some of your surfaces but you can see the density differences.
- With the curves/surfaces alignment off...you won't get a true "water tight" solid model.

...practice the above "basics". ;)
