Rob,

 

If memory serves me = correctly (my build log and pictures weren’t much help), I went = with option 1, but ground out most of the carbon where the phenolic = blocks were to be located so they mainly attached to the canopy = frame.=A0 Keep in mind that these phenolic blocks get reinforced by the = foam canopy rails, so filling any gaps between the two is kind of = important.=A0 Once you get the blocks and the foam installed, = you’ll definitely want to mock up everything on the fuselage to = make sure the gas struts clear the foam canopy rails before you cover = the foam with BID.

Another question for those who have built the forward = hinged canopy.

 

In the instruction sheets which accompanied the forward = hinge kit, it specifies that a phenolic pad 1-1/8 inches square should = be bonded to each side of the canopy frame, 12-5/16 in  rearward of = the gas strut forward aluminium supports. However prior to doing this, = the instructions require 8 layers of carbon uni cloth be bonded to the = inside of the frame, commencing just to the rear of the mounting = positions of these phenolic pads. In fact, from what I can make of the = drawings, the edge of this carbon layup passes neatly through the middle = of the phenolic pad mounting position.

 

The logical options seem to = be….

1.       = Enlarge the carbon = layup area so that the entire phenolic pad is over the carbon layup. The = instructions indicate that the phenolic pads, which are bonded into = place with structural adhesive should have bevelled edges “so the = attaching lay-ups can smoothly cover them” (CH 17 Sup-17). There = is no further mention of the attaching layups. Did any of you folks = apply the phenolic over the carbon and then apply 2 or 3 bid of glass, = or maybe imbed the phenolic between the first 4 layers of carbon and the = last 4 layers? Or maybe put it under all 8 layers? I am concerned that = by bonding it over 8 layers of carbon, then adding =BC in of phenolic = then applying a couple of layers of glass, the whole mounting will be = too thick.

 

2.       = Reduce the area of the = carbon so the phenolic pad mounting is clear of the carbon altogether = and therefore is bonded directly to the inside of the canopy frame = skin.

 

3.       = The 8 layers of carbon = are not meant to be applied all the way to the edge of the canopy. The = diagram however seems not to support this idea.

 

Sorry this question is so tedious to describe, but I would = like to have a clear picture in my head before I start mixing any = resin!

 

Once again, I do appreciate the help I always get when I = put a query on the list.
