When I decided on the Corvair I had already fitted the shorter bolt welded brackets. I replaced these with the non-welded ones that also have the canopy attach point. One thing to keep in mind if you use these is you will need to attach the engine mount while you can still get to the back of the firewall. craig(at)craigandjean.com wrote: > > I think that the factory has taken to delivering the brackets without the > bolts welded on.

With someone's recommendation on their Central Pneumatic Air Compressor (2.5HP-8 gallon, Model 90385) I purchased one and received it a few days later. Both wheels were broken off when it arrived in the box and the motor cover was broken such that it was not attached to the motor. I called HF and they courteously indicated they would send replacement parts which arrived two days ago. The new wheels were easy to attach but the new motor cover had to be modified before it could be labored into position for placement of the attaching bolts and screws. It appeared that the motor cover was either poorly formed or for a slightly different product. Operation of the air compressor is disappointing. Eight seconds after you start using air the compressor motor turns on. If you stop immediately it takes another 50 seconds for the compressor motor to once again turn off. Using its air to power an air shear requires stopping operation about every minute to let the compressor catch up. The bottom line is that if the price is very low, it probably is a minimally acceptable product. I got what I paid for. $119 for this compressor is acceptable if only occasionally used for putting air in your tires but I would not recommend it for building an aircraft. I also got the Air Hydraulic Riveter (Model 93458) at someone's recommendation that it was better than the one from Zenith. I tried to follow the instructions on priming it and put some hydraulic oil in it. The result is that a cloud of oil comes out every time the trigger is activated. I have not yet dared to get it close to the 701 I am building. On the plus side the air compressor is smaller than the one it replaced which had lasted some 15 years. Both HF items can be purchased from me for much less than I paid.

Even a high quality compressor will run its butt off trying to keep up with a tool that uses more air volume than it can provide. That said, I don't know how many cubic feet per minute your shears use compared to the capacity of the compressor but it sounds like a mis-match.

In this approach, you have to have pretty good timing because the speed bleeds very quickly. With a passenger and lots of fuel, extra concentration is necessary. I also will relax sometimes by approaching with some power, and keeping it in until after the flare and the plane's rate of descent is arrested. I suspect that my rather aft CG helps maintain my plane's elevator authority a little longer than the same plane with a forward CG. I have also found operation out of an 800 foot strip to be well within the plane's capabilities, and this included 40ft+ trees at the threshold of one direction.

Does it go to one end of the travel first and then to the requested spot? If so, then it is probably calculating the time to travel from one end to the target spot. The motor speed will vary with voltage and load, so the positioning wouldn't be very accurate. What happens if only one of the feedback lines is open circuit?

On the firewall, you need to keep exhaust as much as 3 inches or more off it so that any electrical pumps, lines or hoses aren't affected by radiated heat. Another good item is wrapping the exhaust to contain radiated heat to where it leaves the pipes. It's very effective. You may, depending on the horsepower output and rpms you run, require a bit more than the half inch for fiberglass. I replaced fiberglass that was that proximate with aluminum pieces that are less affected. They cool better and don't conduct as much heat into the fiberglass that they blend with. First link shows the fiberglass that ultimately browned by the heat. Second link shows the aluminum inserts and the third link shows how paint tends to blend the aluminum and the fiberglass parts so they're not noticed. http://www.macsmachine.com/images/cowling/full/lowercowl1.gif http://www.macsmachine.com/images/cowling/full/cowlfairingsinside.gif http://www.macsmachine.com/images/completion/full/601ezclosefrtrt.gif More pictures on the site if you're curious, Good luck, Larry McFarland 601HDS at www.macsmachine.com kkinney wrote: > > Pardon me if this is a stupid question, what are the design considerations for routing the exhaust system stubs? > Bingelis says the obvious stuff like don't route them too close to anything, I'm hoping for something more specific. > > How close is too close to the fiberglass cowling?
