You might try a water filter dust collector like I use for drywall sanding. I purchased it at Homedepot and it's called an Aquaclean dust collector. I use a DeWalt DW412 palm sander on it with the vacuum attachment. You have to modify you collector hose a bit to make it work, however it does make short work of sanding drywall. It would work the same with the fiberglass dust. Now get back to the labor of love;) Bill Jeffries > I still hate sanding!

The vibration occurs both in the air and on the ground so that rules out control surfaces. I have never had ice on the Revflow. The vibration began gradually and and continued to increase. I'm going to check the balance on the prop again this weekend. Work has me too busy this week, unfortunately. Richard said that maybe as the aerosols evaporated in the finish, (I put a pretty good coat of finish on this time), the prop became out of balance again. Also, there still might have been moisture in the prop from the flood. It didn't appear so, but who knows?

After putzing around in flight simulators, I have finally started flight training a couple of months ago. Have a little over 10 hours of time. Currently, struggling with pretty much everything you can think of. Sometimes feel that I am not cut out for this. A whole new respect for all pilots and especially test pilots, which we all become when we build homebuilts and fly them ourselves. All the emergency landings, troubleshooting, faith in your own design, experimental engines and the increase of complexity due to the fast airplane that a KR is.... truly inspirational! Just wanted to say... hats off... and keep up the good work because what you do is not easy. Very glad to be part of the KRnet and private pilots (soon... I know I will).

I personally think it is a labor of love because you don't make any money at it to speak of, but there is a REAL thrill when your student finally solo's. That is like having a baby! You are just as thankful that they return with all their fingers and toes! LOL I a 4 year CFI with nearly 1400 hours dual GIVEN, and I have soloed 8 students on initial solo's, and have had nearly 80 different students as entries in my book for various levels of training, and nothing is more rewarding than seeing that student doing a good job on that first solo. Ameet you will get there. Right now it feels like you are drinking from a fire hydrant. It does get better. I sometimes think I was more pumped up than the student, and they were just relieved! LOL. This love of teaching and sharing flying is why I am working (slowly) on a documented transition training program for the KR, and will be refining this work at this year's Gathering. MAYBE....if you are short enough, lucky pilots can even get some dual time with me at the Gathering (remember my seats are forward 5 inches).

Make sure the camgear is still properly affixed to the end of the cam. Rings, pistons and rods OK? Were the heads and head studs torqued and all came apart with no looseness? Also check the valve & valve guides for proper clearance--Not just a visual inspection. You also may want to check the valve springs. When I raced Formula Vee's, we torqued the case and head nuts between rounds, and we also checked and adjusted the valve lash. Just make absolutely sure when you re-assemble this engine that every part has the right clearance and meets specs. Good luck and take your time.
