    Design Drivers?

    Maybe you should run home and take your thread with you.

    Design Drivers?

    I got a email BACK from him,once,something, something,no not yet. The Chevy LS 5 can be had for reasonable money(compared to the -7 and its forged titanium rods,etc for $40k)

    Design Drivers?

    Figure on cost per hour plus overhaul,put that much in the bank for every hour flown,fly and forget about it. We have a bunch of adequate motors,but nothing "great",Zoche sure looked like a miracle,as do others but natch on a plane yet.

    Three surface Stall Maneuvers

    An all flying canard surface such as found on the wren,or robertson stol aircraft,should spice up the performance on a three surface tandem aircraft. Make the first and third surface operate differencialy.Done right ,control forces will go up with airspeed,and help to keep it in hand. And of...

    how to locate each holes positions relative to the center of engine shaft?

    How about an abitrary reference point ,three feet from my center,find my bolt hole,extend the line out to the same diameter as my reference,measure, compare to the same radius as my bolt, repeat as many times as nesessary to get a grouping,throw out the outliers and average the rest. Its...

    how to locate each holes positions relative to the center of engine shaft?

    I aint gona machine nuthin,just design and make a pattern/file. For Class A+ machinists to follow.Get a test template made, verify the pattern.Email the file,and the part will just be waiting when I get home one day.

    how to locate each holes positions relative to the center of engine shaft?

    The figure of .006 play was referencing a dry crank with an extension,and yes is theoretical. The point (well taken) is that useing the crank center to locate the pins and bolt holes is prone to errors. An adjustable arm bolted to the crank flange that could hold 2"pins of the size the matches...

    how to locate each holes positions relative to the center of engine shaft?

    I will get to drawings,and then start filling the waste paper basket with those. Right now I am throwing out ideas, and getting better ones. Useing a doughnut/guibo on the flywheel and driving the small pulley will isolate the belt drive from the toroidal motion of the crankshaft and having a...

    how to locate each holes positions relative to the center of engine shaft?

    While I concur with the need to have gear sets aligned in both dimensions to .001 or better,I am left with a quandry as to the value of measuring crank shaft run out when evaluating a motor. Or is crank run out only a broad hint, and that hanging anything like a belt drive pulley off of a crank...

    Current state of Great Plains Aircraft?

    I dont know Pops, you tell some great stories. Some are gems. One in particular where you describe a day in the shop ,setting out to do one thing and then getting sidetracked a dozen times doing some thing else that needed done. Math and the ability to focus are central to building an aircraft...

    how to locate each holes positions relative to the center of engine shaft?

    Ok then one principal is that each hole you need can be treated as a point,on a circle,centered on your crankshaft. And then each hole can be measured for distance to each other. If any three holes line up in such a way to make right angle triangles,so much the better. Plenty of other good...

    how to locate each holes positions relative to the center of engine shaft?

    As the plate you are referencing is clearly a product of a cnc machine,why not back track that part and get whoever made it to use there files to make the next piece you need?

    First applications of composite material in home built or GA aircraft

    You almost got it,they designed while Hittler provided a reminder of what they were about. War. And as a war contingency they designed as to minimise the impact on factory floors,where thousands of ordinary men and women came to work to pound rivets while the bombs fell. No time or energy to...

    Belt Drives and design

    Ok. l will ask for a slight extension on this diversion. The numbers posted about the tensile and ultimate streagth in the article linked suggest that the syretching that does occur,happens at loads beyond other materials currently in use. Yes ? no? and that the implication is the thermal...
