Week 226 - Cowling Part 4

Hours to date: 2141.0

Those of you who are observant will have figured out I am now up to about 85 hours on this cowl project. If you're getting bored with it imagine how I feel!

I had a very down day after spraying on the guide coat and sanding it down - there were low points EVERYWHERE.

My technique had been wrong all along - working in small areas rather than in big sweeping movements at 45 degree angles - as it should have been.

Watching the master Mike Arnold at work I soon learned what to do.

Ironically I have all his other videos on DVD except for the one which shows how to make a plug. If only I had watched it before I started this job it would have saved a lot of pain.

The video in question is here: https://youtu.be/qStFDcZs5Og

If you find that interesting then I highly recommend watching all his other videos - so much to learn from this guy who I rate as the 'God of Glass'.

Anyway back to the amateur - me. 

So what I had to do was cover the entire surface again with a layer of body filler. I've gone through another 4kg tin of filler!

Then sand that off using the big sweeping movements and repeat until all the low points are filled - that's where I'm at now. I've just sprayed yet another coat of primer and it's looking very good, it's not perfect, you could spend forever on this but it should be okay for a mold.  

I've just started making a bridge for the split line as the mold has to come off in two parts due to 'draw' - you cannot remove a mold from a negative angle. In this case the only way to split my mold is along the thickest part of the sides.

I don't think I'm going to get much done this week as I'm off to Barcelona for two days but will hopefully get back on it over next weekend.

Covering with a layer of filler due to my shit technique

Thinking about buying shares in a sandpaper manufacturer about now.

After much more sanding and filling and primer. But is it ready?
 
 Quick video of the cowl as a walkaround. I'm really happy with the shape.
