Status: offline 		I just got a biplane in an auction. The plane does not have an Cowl covering the engine. It works well and everyting, however, it does not look that good with out the Cowling. I have no Idea were I can get one or how to build one.

I am new to this hobby and I need some suggestions.

Thank you,

Paul

Status: offline 		I built a cowl for my Nosen Citabria, using foam blocks carved to shape and covered with glass cloth.
After the resin has set, remove the cowl and dig out the foam.
Needs a lot of filling to get a really smopth finish, but it is OK for a one off job.

I left the engine in place and covered all the openings . I also left the spinner backplate so I would get perfect alignment. Just glue enough foam blocks around the engine.

Status: offline 		Thank you for the advise Tommywatson. However, I am looking for something that is already build. I am not good building or shaping things.

I could not get the picture of my plane yet, since my camera is not working. However, I am attaching a drawing with the measurements of the front of my plane. Maybe somebody can give me a pointer on where I can buy a cowling that fits my plane.

Thank you for your help,

Paul

Status: offline 		If making a cowl using fiberglass over foam, instead of digging out the foam couldn't you use gasoline to melt it out? (Being certain that is wouldn't affect your resin).

I remember hearing of this technique by someone making scale drop tanks. It was useful if you wanted to make the lightest part possible and needed to remove the foam from an encapsulated part. He drilled two small holes and flooded the tank with gasoline.

Status: offline 		Yes that works OK. You can use thinners also. It leaves less residue than Gasoline.

Status: offline 		I'm taking a wild guess here, but your airplane may be a Gee Bee Models Tiger Moth. I used to have one and the firewall you sketched bears a very strong resemblance to my old one.

As I recall the Gee Bee Tiger Moth had about a 44 inch span and the wings were slightly swept. Upper and lower wings had slightly different sweep angles.

If it is a Gee Bee Tiger Moth, you may be able to find a commercially available replacemet cowl. Here is a pic from the tower website.
