The answer is yes, you can use Carbinge with Carbinge Keepers for the entire attachment system for the cowls – no Camlocks or other brand of this type fastener required. For the rear part of the top cowling there is some creativity required but it can be done. I have seen and heard of more than one solution to this problem, but the best way I’ve come up with is to run one pin across the top of the cowl/fuselage junction using a Carbinge Keeper and having the allen head screw inset in a short groove in the cowl. Prior to this, the bottom cowl is attached to the fuselage with one Carbinge Keeper on each side starting from the bottom. The Keepers are made long so that when screwed in they extend vertically past the top of the lower cowl. At bottom cowl installation, they are inserted to the point the ends are flush with the top of the lower cowl. The top cowl is then set to place and the two side pins already placed in the bottom cowl at the rear are inserted further into short runs of Carbinge on the sides of the top cowl. Next the Horizontal Carbinge Keeper is inserted across the back top of the cowl and finally the two horizontal side Keepers are inserted to place and screwed in at the front of the cowl. I neglected to say that there are some screws required to hold the front of the cowl together around the propeller spinner. The most common use is for the horizontal side attachments. If you stick with that you’ll need Camlocks or some other attachment at the rear. This will visually break up your paint job and finish work, will provide some additional drag in flight, and will take more time and effort to install/uninstall. Also they will tend to work and wear as flight hours accumulate. When tools are used to install/uninstall them, the paint around these fittings tends to get dinged up a bit. They attach at specific points depending on how many you use so that the stress on the joint is isolated to these attach points whereas Carbinge with Keepers attaches the parts together all along the joint spreading the loads evenly. You get a more secure fit – less vibration – lower tendency to work and fret. I hope this helps.
