Side view of Martin's fuselage. Looks like a very neat aircraft manufacturing plant with some very neat aircraft building going on. A stringer similar to those on the turtle deck will be fitted from the tail to the firewall to hold the fabric away from internal structure resulting in a nice smooth surface. No oil canning! | |

Tail section with stabiliser, elevator and ailerons in background. The stabiliser has a Birch ply skin. | |

Stan's comments regarding drain holes
---- at least 1/4 (6mm) in dia go in all gusset etc pockets and in wing spars (pressure relief vents in every bay) wing,tail and fuselage lower skins, I use seaplane grommets --- anywhere that moisture could accumulate. Holes to be drilled before varnishing, so holes have varnish on edges and not raw wood. there should be holes as above and in the lower front where there is an inner and outer skin. --- Vent/Drain Holes 1) to pour varnish in
2) to relieve the pressure and prevent blowing the plywood off with extreme pressure changes at altitude (same reason for the
wing spar)---VENTING !!!! This is common to all wooden aircraft .

Checking the canopy for fit. Rick has used gull-wing type doors instead of the forward opening (Piper style) doors shown in the plans. This seems to be a common choice due to a perceived difficulty in sealing/waterproofing the standard doors. In fact, Stan McLeod has devised a number of tilting canopy alternatives. | |

Covering the elevator. The cut-out is for the trim tab. | |
 |
Panel construction started and C150 rudder pedals in place. | |
 |
Rudder covered using the Stitts process. | |
 |
Wing construction a fair way to completion. A masterpiece indeed and a fairly good view of the work involved | |

Another Cavalier originating from Western Australia. It has now moved to Victoria where it is undergoing a freshen up, including some new tip tanks and RV style nose gear. I will update the progress as I find out. | |

I don't think that this one's going to fit through the garage door! I wonder what the neighbours thought when they saw a Cavalier parked in the driveway next door. | |

Ribs fitted to the main spar with rear spars, drag spars and most of the centre spar fitted through the ribs. This procedure is very interesting as only one side can be fitted piece-by-piece. The other side must have ribs and spars fitted together, then the whole lot attached to the spar together. Why? Because, otherwise there is no clearance for the second rear spar to be slid through the ribs due to the already attached side being in the way. | |
| Stan's Diagram |
Stan suggests that ribs are bridged at the top of the spar and slotted at the bottom to slide over the spars. Bridging is cut off after wing assembly. | |

The resulting wing with the D-nose covered with Birch ply and you can clearly see the flap handle in the middle of the seat section. | |
 |
A very nice canopy set-up indeed. | |
 |
Nose cowling fitted to the front of an O-290 engine. | |
 |
Nose cowling plus a nice big spinner. | |
 |
A slightly different view of the clecos and masking tape. | |
 |
The top of the engine cowling open for inspection. |
