Pictures of the front cockpit cover.

Thanks John. Could you post a couple pictures showing the installation? Maybe a closeup of it installed and a couple of the backside of the cover and the method of attachment? Sounds like an idea I may try myself when I get to that point.

Sorry, sometimes the connection from eye to brain breaks down. I obviously read the question as "front cowling".

When cutting the cockpit hole, the piece removed was saved intact. The outer edge was lined with an "h" moulding. A pair of strap fittings from West Marine were attached to the cover more or less at the widest part and inboard of the edge enough to clear the padded combing. The cover is held in place with a couple of 1" straps with velcro attached running down through the plywood former adjacent to the front seat. A light aluminum "L" bracket was formed and riveted toward the rear of the cover to maintain the longitudinal position. There does not seem to be any air load on the cover. It does make the rear cockpit less breazy. The first few flights were without the cover and the draft brought the dust that had eluded the vacuum during construction up into my face.

Right Doug, sorry if I wasn't clear...although I do like the cowling as well. I was wondering how to add a front cockpit cover if I had a padded combing around it. I looks as though you solved that problem.

John,

I think Dave was looking for info on the cover for the front cockpit hole, not the cowl.

The creation of the front cowl was quite simple but too detailed to be added to this string. If there is interest I will post another message with the details. Some information is avialable in the archives.

As a introduction to the process, there is no structure forward of the firewall supporting the three cowl pieces. Each is attached to a flange that is riveted to the firewall and each other in a moncoque manner. Time will tell if vibration will cause problems down the road. A friend who did similar but added bracing has actually suffered greater vibration damage, possibly because the cowl is so rigid in a vibration rich environment.

Looks good John!

Any updates you'd care to share with us regarding the plane and/or the Rotec?
