I am going to have new Diehl like gear upper attach brackets made. They will be a little taller than the Diehl castings to fit the AS5048 spar better and they will be a hair narrower. The main reason I am doing this is to give me more ground clearance. I am changing the angle of the legs fom 50 degrees to 57.5 degrees which will give about another 1 3/4" ground clearance. They will be cut from 6061 aluminum plate with a HyDefinition CNC plasma cutting machine, have the holes drilled exactly the same on both brackets on my milling machine so they are reversible, have all corners radiused, be welded by a professional aircraft welder with more years of experience than I am old, then heat treated back to T6 by Braddock Metalurgical.
If anyone else is interrested in a set please contact me offline at br...@engalt.com. They will be around $250 a set depending on how many I do. I am basically ofering them to cut down on the $175 minimum lot charge on the heat treating and the other one time costs. I am doing this one time and ordering metal Monday and will not make any more after that. I will also do a set of longer bottom brackets in 4130 in the next week or two done at the correct angle. Keep in mind that this will make the gear less springy, you will have to come up with your own glass, Scotchply, or aluminum legs, the bottom brackets are not included and I am not sure what they will cost yet, and I am not an aeronautical or structural engineer and make no warranties as to the suitibility of this to the KR or any other aircraft. I am just using them on mine and trying to cut the one time costs some. If anyone wants a drawing email me. Also, if anyone has any other 6061 aluminum to be heat treated and wants to share some of the minimum charge let me know. I will be doing some 4130 and some 1095 in the future also, but those minimums are only $60.00. Brian Kraut Engineering Alternatives, Inc. www.engalt.com
