    Hi John, what you are doing is inspiring. I would like to know if this is funded with your own resources, or have you managed to secure some VC or similar funding? Thanks Kind regards Daniel

    Why split pins are the safest option for securing bolted connections

    I'm glad that this has opened a discussion, as this is quite important. It's obvious that Nord Lock are trying to run a business and sell a product, but so do nut and bolt manufacturers. Anyways, hope this helps. To be honest, I won't be building anytime soon, because of m.o.n.e.y. or lack of it ;)

    Why split pins are the safest option for securing bolted connections

    Amazon.com: Shigley's Mechanical Engineering Design (Mcgraw-Hill Series in Mechanical Engineering) (9780073312606): Richard Budynas, Keith Nisbett: Books if anyone's interested in Shigley :) The guy did say that the test they use for presentations is quite extreme. Aparently it was designed by...

    Why split pins are the safest option for securing bolted connections

    What I remember is that the red ones are plain nuts, green blue and purple are nyloc, ovalised nut and spring washer, and lastly the very flat ones are nord locks.

    Why split pins are the safest option for securing bolted connections

    Hello, I don't post much these days, but I thought this may be useful. A salesman from nord lock came in to the place I work at the other day to peddle their special washers and showed us a vibration test using various nuts (plain, nyloc, ovalised, and their own of course) and the graph...

    Steam power ????

    I've read an article on the six stroke engine. Quite fascinating.

    Steam power ????

    Right, supposedly, our normal ICE produces 100 HP continuous at whatever rpm, the efficiency is 35 % and another 35% is in heat. That is another 100HP. The question is, how much of that can be restored. I have come across some vague info, that someone has come up with a solid state heat to...

    Steam power ????

    This is all very interesting. It reminds me of a project Honda has developed for retrieving heat energy from the exhaust of a normal piston engine. Look it up on wikipedia. The idea was to have a hybrid set up like the Toyota Prus or the Honda Insight/Civic, and combine it with a steam turbine...

    His airplane is made that way cause it's just another way to make an airplane, just like you have ways of building bridges or refridgerators.

    Topaz, again, I understand where you're coming from. I'm very much into music (not creativly tho), and I know why this is an important issue, but think of it this way: An artist strives to create sth absolutely new, stunning and original, an engineer will take what other people HAVE THOUGHT OF...

    Again I'll go even further. General aviation over the years has developed a model for sheet metal building that has been copied many times over in numerous designs. Do you see Cessna suing Piper over Beech'es design techniques? Or maybe they should not use the same engine manfacturers? Or...

    KR series is another example. It wasn't KR who made new airfolis for the aiplane, nor it was them who started using the Corvair engine on it. To be able to use either you need separate analisys, and if you look at numerous two seat low wings, they all look similar, but will have different...

    Think again of computer software. I use Open Office. I don't want to spend money on the expensive Microsoft product, and I don't have to, because someone took the latter design apart, and designed their own with a new name and made it accessable to others. THAT is what this thread is about in...

    Again I can't agree. Please don't take it as arogance, or an attempt at flaming your opinion. It is only my view. Ferrari is popular due to many reasons, the performance, prestige and the styling. It took an artist to draw the lines of a ferrari. How many people would be able to recognise the...

    I don't agree. In spite the fact that I never graduated Technical University I attended, what I learned there, was that copying is the most common means of any design process. With all due respect to engineers who designed their own mashines, you can take one bit by bit, rename it, and it will...

    This can go on forever. If you really want to make a true open source airplane, someone needs to design one, and THEN post it on the web for people to make changes. Only then a community could build arond this design, and people could chuck in, one main version could be developed, with mods...

    pusher prop---mini-imp

    From what I understand, reflexing the flaps up for the cruise doesn't affect your final approach, because you would had long changed their position to down for landing. From what I can recall from my flight training, I deployed up to 20% of down flaps before turning to the final. Perhaps Orion...

    Project update

    No offence, but it seems to me, that it's been long since first pioneers did that. In my country, I'd be required to present a full documentation checked by a qualified engineer, and then get a two year time frame to build it, for which I'd need to buy a "licence" that needs renewing each two...
