Status: offline 		No, no, mart. No back burner for my "woody". As a matter of fact it is an inspiration to get my project done faster. I had to buy it because it was a steal and I saw it run. Boy, does she fly over the water, you wouldn't believe it. My budy bought the newest version of the Insane Hydro and it is not any faster in my belief. Right now I am fabricating the cowl/canopy and the rear wing. Pictures to follow soon.

The Insane looks good. I hear that hull is crazy fast, Insanely fast you could say, haha. I bet you and your buddy are doing some serious bench racing about your wood hull against his new Insane, eh? Looking forward to your cowl build pictures, take care.

Scott

if I am nearly as fast as the Insane I will be happy, believe me. All my buddies at our club run modded Zens, mine is (still) stock. But who knows? I might have the "wonder boat" created

Status: offline 		Sorry it took so long to get back to you, been rather busy. As for the sponson AOA, most of the boats out there use a 3* rise, or upward angle from a 90 at the sponson transom. Any less than 2.5 will have the sponsons dragging while any more than 3.5 will cause planing out problems. As already stated, NEVER THIN EPOXY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If you go to the West Systems website, it specifically states the adverse effects of doing so

Status: offline 		Thanks, HJ. That's what I figured. 2.5° seems to be the perfect angle. I guess I have to increase mine a tad to get to the required 2.5°. No big deal. An additional piece of ply glued to the bottom, tapered out toward the front and we are perfect .Regarding the thinning of epoxy resin, it really is not that critical. I've been working with epoxy resins for the at least 25 years and you hear all kinds of comments what can do and not to do. I have never heard of thinning being a bad idea. Nor have I experienced any adverse results by doing it. You should not thin with aceton, but denatured alcohol should be O.K.

Status: offline 		Worked diligently on my wing set and the cowling. Got the foam sanded to shape. Pretty much ready for the balsa planking job. Got to finish my Miss Budweiser, too. Man, too many projects . But I love it that way. Check out the pictures of my progress.

Nice work. The foam shapes look really well sculpted. Your wing looks good too. Can't wait to see the glass work. Take care,

Scott

But it really wasn't that hard to do. That foam sands easily and takes shape in no time. All it's left before planking is a balsa nose piece and a balsa block for the scoop intake. I'll take pictures of the process.

Status: offline 		O.K. guys,
next step of the cowling project was to make a balsa ring for the air intake scoop. Also the nose cone was mase from a balsa block and replaced the foam nose. The planking is really nothing special. It goes on easily and quickly. The cleaning of the fingers takes sometimes longer than the actual wood work . The reason why I procrastinate with this project right now is, I am having too much fun with my "Insane" Hydro. But slowly I am getting there

Status: offline 		dicko, not yet. Planned on doing all the glass work over the weekend. I still have a liitle wood work left to do on the inside of the cowling, which is a ply wood ring that strenghten the open rear end. Other then that, after glassing an a lot of sanding comes the finale-the paint job
