I bought a 4*40 that was all ready built off a fellow but I wanted to add a cowl to improve the looks. I found the link to the renderwux website and used some of Tom's ideas. However I didn't want to be bothered with the cowl mods. What I end up using was a Sig Kougar cowl. I was running a Saito 56 at the time ( I have a .72 now) and I mounted it inverted and cut out the bottom for the cylinder head to stick through. This looked really sharp and the best part was that I had a removable cowl for easy access!

I like this method so much that I used it to make the cowls for my duelist! Give it a try you'll like the results!
