A Family Project Starts Right at the Factory - Day 1 & 2

Yesterday morning (Monday), Lon Boehme, his brother Val and his son Barry pulled in at the Zenair factory in Midland with their 12 ft. trailer in tow. They had just spent the weekend driving in from Alberta (34 hours!) for a promising week: a Wing-building program, a rudder workshop, and a trip home six days later with a partially assembled STOL CH 750 airframe kit in the back! Here is a short running summary of the experience...…

progress on CH-750 at Cloverdale

I am two weeks into working on a quick build kit at Quality Sport Planes in Cloverdale CA.  I continue to be very pleased with the help I receive and with availabilty of special tools and knowledge of Doug.  Every day I get more done and am getting closer to the point where I can move  the project to Alaska to install the engine.  I recommend this company to anyone who may want to keep things moving along on their project.

Rudder Skin

Drilled and ceco'd the rear rudder skin today. Also slipped on the nose skin but ran out of time before I could do anything but tape it down.

Flutter testing

Back in March 2010 we offered $750 to Zenith Aircraft Company toward their flutter testing expenses. The recent Zenair News includes information regarding the latest flutter testing on the XLB, therefore we are sending our check today.  We feel we are indebted to Zenith for their continued expensive testing.   The additional testing is reassuring to us, and we commend Zenith for their continuing professionalism.  Wes & Lurlene Bressler, N601WL, Jabiru 3300, 50 hours total time.

Article Reprint: Safety Is No Accident: Zenith’s aircraft are high-utility contenders. So how’s their record?

Finally... spars completed!

PLEASE tell me the spars are the hardest (physical) component of this plane to create.  After 286 solid AN5-6 rivets my left shoulder, neck and lower back are aching.  I know there's a few more to go... some longer ones on the spar root fittings, a few in the cockpit, not to mention those pesky little 3-3 suckers on the trailing edge... but I'm over it.  After this plane I never want to see a solid rivet again, let alone set one.  I'd have a ceremonial "chucking the bucking bar" in the dam,…

Cut Down Header Tank

Decided to cut down the header tank. It just didn't fit well, and seemed too large/heavy for it's mounting location. New total length is just shy of 19 inches with 8 inches in diameter.

Volume of a cylinder = 2 x pi x R x length, so 2 x4 x pi x 18= 452.38 cubic inches/ 231 (cu in per gallon)= 1.96…

More Rudder Work

After several weeks of cold weather and business trips, I resumed work on the rudder this weekend. Sprayed Zinc Oxide primer where needed on ribs and spar. Cleco'd everything back together and then got to use my pneumatic riveter and air compressor compressor for the first time. One bad rivet had to be drilled out and re-done, Next weekend, the skins.

getting started on my quick build 750

I have spent the last week at Quality Sport Planes in Cloverdale CA working on my 750.  It has been a great week with Doug giving me just the right amount of advice.  I will be here for another month working on the project before trailering it north to Fairbanks Alaska to put the engine on.  I am very happy working on the project here in Cloverdale.

Mated rear ribs to spars

Located rib locations and drilled spars. Had to remake one rib out of this set (#2) all in all I'm happy with that. Time now to clean, sand, prime & finish spars.

nose gear bungee life

I have 6 yrs.( 300 hrs.) on my original nose bungee. Is it time to replace? I have no sag or signs of deterioration. How often are other 601 xl owners doing a replacement?
