Hi. I've search for some threads on how to build a cowl, but haven't found a good step by step technique. Are there any sites, mags, etc. that show step by step intructions?

I am currently building the yak 3 from redstarrc and it has a balsa cowl. Take a look at the manual it has some pics that might help. www.redstarrc.com

Have built basla cowls before and now I go for the ease of ordering a fiberglass one and gives me much better looking front end

You can make a fiberglass cowl using the "Lost Foam" method. Here is few photos of a recent one I made. Laminate blue foam sheets to get the size you need, sand to shape and glass the outside with fiberglass cloth and epoxy.

Once the epoxy cures, melt the foam out with acetone or gasoline, I found that gasoline works as well as the acetone on blue foam.

I used balsa where finer detail is necessary

Tony,
That cowl looks great. When you say blue foam do you mean the stuff that home depot sell's that is about a half inch thick and real smooth? Also what weight glass do you normally use. I need to make a cowl and a set of wheel pants and this will be my first attempt at it.
Thanks

This is probably what you are looking for:

It's from the Sept. 2000 issue of RCM

Krossk,

Talk about timing! I am building a Sig Mid-Star and contemplating a cowl. I am at that point in the build so this is very timely stuff! Thanks for posting!

I can't take credit for the original posting. Someone else posted it for me a while back and I just happened to have a hard-copy laying here with the links to the pages printed at the top. It is, however a very good article to have in one's reference library...

Yep, copied and filed away. I was hoping you had the originals as a few of the scans could use a touch-up or two . Oh well, its great information nevertheless.

Yet another reason to love these forums.

Import it to Acrobat then increase the size. It will be plain as day.

Agreed. Probably wasn't very clear in my prior post . I was thinking it could have been copied better - leaving out the gutter of the page ... small stuff that really didn't effect the readability of the piece, just asthetics. Hummm, I guess that same rationale is what keeps my kits on the building table longer - always trying to make everything just right and asthethetically pleasing.

I'm the "someone else". Thanks krossk. I used this articlt to build a cowl on the tiger 2. I can re-scan the article if you like. What pages do you want posted?

Mods

Yep - that's right. I guess the memory's going faster than I thought.
So how's the ModKat coming along? Haven't seen any updates for a while.

I know my last update was on 3/19/07. Sanding is taking its toll on my sanity. Good news is that I'm pretty close to making the molds and my telemetry from eagletreesystems came in.
