Unfortunately, I didn't discover the problem until after drilling/clecoing the skin. After rechecking and not finding anything wrong with my measurements, I cross-checked some of the measurements in the plans and found that there appears to be a descrepancy of about 8mm between where the assembly instructions advise to place the leading edge bend (which is where the actual bend in the kit-provided skin is) and where the bend should actually be. I cut and bent a new skin offset from the original, back-drilled the holes from the original skin, and everthing then went together perfectly. Having a blast--with this exception the plans (and kitted parts) have been great.

The plans do tell you what the thicknesses are. .016 is most of the metal on the 701. There are .040, .062 etc. but only for specific places.

Most noticeable on the left side; hose is almost squeezed flat. I have checked all measurements for the various parts/pieces associated with this portion of the assembly. Looks like maybe I need to replace lower hoses for front cylinders with slightly longer hoses so as to curve around heads of Barry mount bolts. Of course this will increase quanity of coolant needed, thereby increasing weight, increasing fuel consumption, etc, etc. Where does it end? Any input appreciated.

You can remove the waterpump fitting from the engine, warm up the points where the hose connectors enter the fitting and then rotate the connectors upwards. This aims the hoses upwards to pass over the engine mounts. I made a wooden dowel fit into the connectors to get a grip for rotating them. When they are warm enough they will rotate easily.

I used a scrap hose sleeve over the hose where it contacts the bolt head, to avoid abrasion and secured the sleeve with a wire tie. The FAA inspector gave me a 'atta boy' for this as he said this is a potential area of failure... where a vibrating item is in contact with a rubber hose. Also, those hoses are metric and my NAPA auto store couldnt match them for proper diameter size.... !!

It is comforting to know that having four days off work two weeks in a row didn't cause mental collaspe. All comments appreciated. I have reviewed all the ZAC construction photos and, yes, it is a tight fit. Another problem solved via the Internet. Have managed to clean workshop, haul off all trash, donate an 18 ft long one-piece table to the local volunteer fire department (bring on the fund-raisers - they'll have a place from which to serve burgers, BBQ, beer and baloney). I did get all the remaining parts into ONE small box, and sorted other stuff into boxes marked "Instruments", "Electrical", "Fuel", "Brakes" and "Misc". The last one is the tuffy. This next is not a "rub-it-in" ----- it was 79 degrees in North Texas yesterday, 75 today. I fear Mother Nature will soon remind us of the calendar. Thanks again, Zed Smith do not archive
