I mounted a venturi ( horn) on the left boot cowl for the vacuum and mounted the filter inside on the left boot cowl . Haven't flown yet but it looks kind of " airplanie". I went with the Vertical Card Compass rather than the DG. Was advised that since GPS, the DG was added expense I could do without.

For my cowl I am going to buy a nose bowl and make a custom aluminum cowl like on a Piper PA-11. I am going to use a Pitts style nose bowl. I have seen this type of cowl on a 601 and it in my opinion looks excellent. They are not too difficult to make from scratch. Just copy the design from a Piper rag and tube aircraft. Fibreglass nose bowls can be purchased from ACS or if you prefer an aluminum bowl check with the aircraft wrecking yards. Your other option is to make a female mold to form a custom fibreglass cowl. Lots of info on this method is available on the web, in books, and in old Kitplanes issues. Personally I don't enjoy working with fibreglass (one of the reasons I am building a metal plane) so this method is not for me. Brian Caithcart Saskatoon Sask.

Do not archive ----- Original Message ----- From: "Steve Dixon" Subject: Zenith-List: ZAC Pneumatic Rivet Puller > --> Zenith-List message posted by: "Steve Dixon" > > I recently bought one of the rivet pullers ZAC sells, and it continually leaks a small amount of air through the system. It produces an audible hiss as long as it is connected to an air line. In spite of this it seems to work just fine. I need to determine if the hiss is normal in which case I can learn to ignore it, or if I should contact ZAC and make arrangements to return it before too much time goes by. I previously had one of the Harbor Freight pullers which didn't leak at all.

I picked up the zenith cowl with my kit (currently for sale, please reply off line if interested. zenith quoted $375 plus shipping) and was not impressed with the design. Skyshop has a cowl from Czeck aircraft that they want 385 for, but the design is the same as zeniths (substandard in my opinion, although Danny at Skyshop says their workmanship is better), though their shipping is cheaper. Mine will be considerably cleaner and is built around a mounted 912ul engine on the nose of a 701. My process is: 1) Wrap the engine up tight with plastic and duct tape (those that ran out after the last scare and bought up a bunch to seal their houses should have a ready supply, for the others, the stores have restocked). All round the engine, exhaust, and tape to the firewall. The front of the radiator and oil cooler will just need duct tape to cover. 2) Form the basic shape using poster board and duct tape. 3) Continue forming the basic shape with chicken wire. 4) Expansion foam over the chicken wire. 2 part foam is preferable, but sometimes hard to acquire due to shelf life. Gap sealer foam from your local hardware store of the type used to seal around pipes will work (and is what I am using). Use the minimum expansion type and do not try to spread with a trowel. That's sort of like trying to shape a soap bubble, with the same results. 5) With a body file or similar, form the foam undersize from the final contour desired. Note, if the foam comes real close to the final contour, it will continue minor expansion somewhat for some time. Just dig out the bubble of foam with a knife and reseal and recontour with plaster. Want to know how I know this? 6) Build up with plaster to final contour (the step I'm on and should be finished with this weekend). I'm using Ultracal 30 made by United States Gypsum. It's a minimum shrinkage plaster. Build in thin wet coats (goes on well by hand, just coat your hands well with vaseline to protect yourself from the cement and silica in the plaster), after the initial heavy coats. While still wet but fairly well set up, it can be shaped with a body file. For the underside where the plaster wants to fall off, mix with hemp fibers (non-smokeable, completely legal, probably can be gotten at the same place as the Ultracal, and about $135 a bale). Final contour can be achieved by bodyfile, vixen file, drywall sanding equipment, or whatever you are comfortable with. One note, you will probably want to use some water with the sanding. 7) Scribe the split lines for your cowl sections. On mine I will have a split line for the upper cowl, and a split line down the center from the prop shaft all the way under to the rear (to allow me to pull the lower cowl mold due to mold lines without breakage). After the two piece lower sections have been pulled from the plug, they will be rejoined with glass. 8) Shellac the surface. May take a wet sand and a 2nd coat to get a good seal of the surface, and to remove imperfections. Make sure the scribe lines in the plug are still there. 9) Mold wax, parting film, whatever it takes but do a thorough job, do not skip this step if you want to be able to get the mold loose. 10) Gelcoat, brush or spray on. This will be the finish surface for your mold. 11) Lay up the individual mold sections with excess. The scribe line will mark where it needs to be trimmed back to. 12) After breaking the mold loose from the plug, put it back in place and reinforce. I intend to used 3/8" aluminum tubing with a liberal coat of plaster and hemp. Should be about bullet proof, and legs can be added also to get the mold up to a working level or at least stabilize so that it don't rock and roll while trying to lay up the actual cowl. By this point you should be far enough along, and have a good enough understanding of the process, that further comments from me about the layup of the actual cowl would be rather pointless. Good Luck! By the way this plaster and hemp portion of the process is what our plaster pattern makers and tooling people here at Boeing Wichita use. When I am done I will have a mold that should be suitable for building multiple cowls if there should be a requirement. Or I may just have a mold for sale.

Then all I have left are the details. 90% done & 60% to go. nhulin wrote: > --> Zenith-List message posted by: "nhulin" > > Listers, > > Please reply to the list on this one.

After all, that's why I decided to build an aluminum plane. Which nose cowl will that be in the ACS catalog? The only ones I've seen with explicit dimensions are 35 or 36" wide and this is too wide for what I want. When I was considering that option, I was looking for about 32 wide. --- Brian Caithcart wrote: > --> Zenith-List message posted by: "Brian Caithcart" > > > Neil and Michel, > > I am building a CH601HD.
