Visited the Ray Allen booth at Oshkosh and looked at their trim servos. Just $125 bucks, 4 oz., and they measure 1" x 2.3" x 2.75". I know its a bit too high tech for a Piet but if DJ can have a digital engine management system why not? (Need a battery of course).

Running a 600 hour C65 but with mixture permanently wire locked rich. I imagine you were leaning out on every trip regardless of altitude - is this correct? Following some of the engine related presentations at Oshkosh I think I had better take out some plugs and have a look at them. My understanding now is that a weaker mixture is actually good for engine longevity so I'm now thinking of fitting a mixture control.

I've been interested in the dual mag setup for the A-Model engine which he markets. I would guess that he had this product installed on his engine.

From: "Textor, Jack" Hi all, I'm looking at Planers for building the Piet. I saw positive comments in the archives on the Delta. The Deltas I've considered have been 12", two blade, and one speed variety around $250. I'm also looking at the DeWalt 734 which is three blade, one speed at $370. And also the DeWalt 735, three blade, two speed at $500. The best pricing for all seem to be at Tool King. Would appreciate any comments on these thoughts. Thanks, Jack T Des Moines ________________________________ Message 7 _____________________________________ Time: 01:57:25 PM PST US From: "Michael Turrell" Subject: Pietenpol-List: Re: Planer help All the machines you mentioned are good,but what you want to look for is "how easy is it to change blades" I run a Ryobi in my cabinet shop and the blade change is a snap,takes me about 10 min. no brainer type of setup.Also how many sharpenings are you going to get on a set of blades(I know Delta were very skimmpy when I looked a few years back)? On the Ryobi the machine will likely burn out before I run out of blade to get sharpened,allthough somtimes I wonder,as I have been using it since 1995 and untold thousands of board feet have passed through it,but my guess is they all will stand up.Just a couple things to consider.Mike ________________________________ Message 8 _____________________________________ Time: 02:41:28 PM PST US From: Isablcorky@aol.com Subject: Re: Pietenpol-List: Planer Help????? Jack T, Since you brought it up I will comment on the subject. I have mostly Delta tools in my shop as that was what was offered at the PX where I shop. I wish I had gone elsewhere. Drill Press. Chuck hangs up when trying to go to large shank drills 10 in Table saw. So cheaply built one can't saw a true straight cut Mitre Saw. Have never been able to square the blade vertically Electric sander. satisfactory Mikita drill, Cut off saw and Bosch grinder are all great. What I'm trying to say is go the extra money and get something better than Delta Don't have a planer or joiner as I have access to the woodshop At Barksdale where they have heavy professional grade equipment. ________________________________ Message 9 _____________________________________ Time: 02:54:08 PM PST US From: Rcaprd@aol.com Subject: Re: Pietenpol-List: Adventure '05 Crunching the Numbers In a message dated 8/4/2005 11:47:15 AM Central Standard Time, Mike.Hayes@denco.co.uk writes: I imagine you were leaning out on every trip regardless of altitude - is this correct?

My understanding now is that a weaker mixture is actually good for engine longevity so I'm now thinking of fitting a mixture control. Mike, I have been leaving it full rich, until I get to an altitude of 4000 or 5000 msl. My next time up, I'm going to follow Chris's suggestion about leaning it out before that. If your engine is running rich, it will deposit more carbon in the engine oil. Another possible cause of running rich, is a float setting that is too high. Does your carb ever drip fuel ? And a possible cause of higher fuel consumption might be using a high power setting, in attempting to sustain a higher speed. I'm pretty sure I can get a consumption of just over 3 gal / hr, if I fly at just over minimum controllable airspeed. For my plane and instruments this is at 1750 to 1800 rpm, which nets about 55 to 60 mph indicated. Can't get there quite as fast, but it's a great way to just take in the beautiful scenery !! Chuck G. NX770CG ps It looks like this weekend I'll be doing some high altitude tests. ________________________________ Message 10 ____________________________________ Time: 03:14:35 PM PST US From: "James Dallas" Subject: Re: Pietenpol-List: Adventure '05 Crunching the Numbers Chuck, The speed you are looking for is Lift over Drag Max--the point where induced drag and parasitic drag co-incide. The slower you go the more induced drag due to lift and the faster you go the more parasitic drag increases. Wished I could've made it to Broadhead, but Uncle Ray wouldn't let me off.

I have a delta, and it works just fine. It is set up with blades that are mean't to be thrown away, they are sharp on 2 edges so you can reverse them. It costs just as much to sharpen than to buy a new set. but I have a machine to sharpen them, so I do sharpen mine. Del "Textor, Jack" wrote: Hi all, Im looking at Planers for building the Piet.
