Subject: Re: Pietenpol-List: LANDING GEAR - SPLIT AXLEBart, Our plane isn't flying yet -- hopefully the end of next summer. We madeour struts as per the plans and had no real difficulty bending the 13gauge steel (4130) to fit inside. Then I just welded it up. I don'tbelieve we are going to have any problems with this and with the weightof the airplane bouncing against the bungee cords, you need all thestrength you can get. This area is really going to take a beating as itdoes in other similiar airplanes.John LangstonPipe Creek, TXnle97(at)juno.com________________________________________________________________________________

Pietenpol-List: LANDING GEAR - SPLIT AXLE
Original Posted By: nle97(at)juno.com
I am currently looking over the landing gear section of the Piet drawingsand have a concern with the 3/4 inch 18 gage tubes (shock struts) and theirend fittings. The end fitting consists of a U-shaped 13 gage reinforcingstrip welded in slot in end of shock struts. According to an EAA weldingbook this design is not good because of too much cold working and welding.I drew up an end fitting using what the EAA book recommended. Now I amstepping back and thinking that the recommended end fitting looks like a lotof maching and $$$. Question: Has anyone ever seen the shock strut end fitting design shown in the plans fail on a Piet or have cracking problems. Asalways, I am looking at the most simple/practical/least expensive means of construction. I would prefer to stick to the plans but wantto produce a quality product. Any and all comments welcome.Thanks, BartBart ConradBoeing Field Service Rep - Hobby FieldDouglas Products Division & 737 Hvy MaintPhone: 713-640-5882Fax: 713-640-5891E-mail: bart.conrad(at)na.boeing.com________________________________________________________________________________

Most of the flying has been from hard surface runways except for acouple of trips to Brodhead. That was hay fields. ( ask Andy King ).Anyway, I'm not the best pilot in the world, & let me tell you I have madesome hard landings. Dropped it in from way up. In fact one time I thought Ibroke the spar.The gear is still there, as good as the day it was built & with the originalshocks cords yet.I think Brenard broke the code.Mike B Piet N687MB ( Mr Sam )________________________________________________________________________________
