Matt Paxton was not able to fix his gear in time to take off for Brodhead so is staying behind. Jack Phillips blasted off after the fog lifted:"The fog is getting thicker.""And Leon's getting larrrgerrr."stop short of Brodhead and come in tomorrow, but one never knows. I had my Cub up for an hour today. Interesting thermal activity in this 98 degree heat. I will try to take some pictures and post them tonight for those who can't make it for Holy Week.-john-http://www.cafepress.com/half_fastJohn HofmannVice-President, Information TechnologyThe Rees Group, Inc.2424 American LaneMadison, WI 53704Phone: 608.443.2468 ext 150Fax: 608.443.2474Email: jhofmann(at)reesgroupinc.com________________________________________________________________________________Subject: Pietenpol-List: Water versus Laser cutting metal parts.

We manufacture a lot of parts for airplanes and we use water jet only. Thereason is a laser will case harden the edge of the metal part. First whenyou drill out a hole you will mess up a drill bit really bad. And if youhave to bend anything the edge will crack unless you polish it. I think youcould use laser and your parts would be just fine as far as stress. Thereare just those drawbacks I talked about. I am building a Piet and we arethinking of offering up some metal fittings for the piet.

Jeff,I have the same set up as you except mine is a C-85. I can't remember about thestarter gears, its been too long since I had the engine apart. Although I thinkthe starter gear was left in place behind the rear gear case. As far as theauto gas goes. I have an all metal fuel system and a steel needle and seatin the carb. The only rubber I have is aircraft quality Airquip hose betweenthe gascolater and the carb. I have not had any issues with that piece of hose.The only actual issue I have with the auto gas is that the O-rings on thefuel drains need to be replaced every annual due to swelling. That is it. Idon't worry about the fuel additives since it is too cold to fly above 9 or 10thousand feet. Just put a little marvel mystery oil in the fuel occasionallyand all will be fine.

I guess the string bit would be a lot cheaper than renting a transit. Good luck. Sounds like you are pretty close to covering. Wish I were that far along. Just finishing my right wing. Left wing should be a lot faster -- I'm learning what to do on the right one. Fuselage is about half finished. Still need to build up the landing gear and engine mount. Maybe I can make it to Brodhead next year. C ----- Original Message -----

Hi womenfly2.....yes I agree with what your saying and look forward to seeing whatyou came up with. Surely if someone could make the metal parts in bulk itwould have to be cheaper as you would get a better deal when buying materialsin bulk. Obviously labour is added to that but someone like me who is time poordue to family commitments, I would rather buy these parts ready made and getflying sooner than struggle through wasting time sourcing materials and doingit etc. Its a fine line and judging by other responses here, im not the onlyone.Even supplying the parts flat and undrilled so each individual can bend and drillwhat needs bending and drilling to fit their own project.As an example, the prices I obtained for 4130N are as much as $45 a sq/foot herein Australia.

Scott,I cannot help you with pictures as I am not able to go this year either. I havebeen 2 years in a row but this year life got in the way. I had an email froma friend I met at Brodhead last year and it struck a pang of disappointmentthat I would not be able to hang out with him this year. He gave me my firstride in an GN-1 last year which is what I am building.I see that you are not too far from me. I am in Remsen NY which is just northof Utica. We should get together one day and compare our progress.I bought a GN-1 about 75% complete with a Corvair engine. The 75% is misleadingas I spent 2 years figuring out what the previous builders did, and then 3 yearsmore undoing and redoing things I did not like. This spring I started intothe engine which was supposed to be redone but lacked the care that I wantedto see. I attended Corvair College #20 and learned a whole bunch. I will probablyreceive my heads back, totally reworked, on Monday and can begin to reassemble.Once that is done it gets put on the airplane to check weight and balanceand then the fuselage gets covered.
