Hi all,
I’m at the stage in my tri gear conversion where I need to think about how I am going to cover the hole in the belly and I am looking for ideas from those who have gone before me…. Think light 😄
My initial thought is to cut some 3 mm foam and cover it with some plies of uni on each side. I would have a couple of access holes or perhaps one oval shaped hole.
Any suggestions would be appreciated.

Hello Paul,
Well I recently closed in my mono hole and followed instructions that Bud posted (or emailed me, can't remember). I started by doing 3 layers of bi-direction cloth on a glass table and used a vacuum bag to make it flat as possible. Then taped that up against the bottom and traced out the hole from the inside. Then I used G10 board as the access cover plate and cut that shape plus an extra 5mm or so. From there I freeCAD designed some spacers to give a nice even 2mm gap around the access G10 cover and placed that in the hole and filled the void with flox and over lapped with 3 layers of bid to mount nut plates to later. With the trace line cut I held the patch in place with tape and ran 3 layers of bid from the panel to the side walls to glue in.Â
Its now complete but I have a video that talks a little about it here. https://youtu.be/7auXi3WRYwc
Hope this helps,
/Kyle

My Classic Trigear conversion uses a large, rectangular, removable aluminium plate over the whole hole. This is held in place with screws that attach to L-shaped aluminium brackets glued around the bottom edge of the hole. Gives easy access to fuel pipes, brake pipes and cylinders and various cables that run inside the former wheel well.
The aluminium plate also makes a great ground-plane for mounting transponder and EC aerials!
