Another BFN Rebuild

Ha, thanks Tim. The damn thing still isnt done yet though and the 4th is upon us... GL is only a few weeks away so it better get wrapped up soon.

As promised, here are some updated pics.

As mentioned previously, we covered the entire floor with 3 layers of glass. The front (foamed) section got mat/cloth/mat, the coosa got cloth/cloth/mat. I also ground the hull down and we put 2 strips of biax down the middle.









You can also see that the angles to raise the gas tank had been bedded. Here are the front stringer blocks bedded (they have since been filleted and glassed). We figure a little extra support between the stringers to keep everything straight wouldnt hurt- after all, the mains are quite a bit taller under the engine than they were originally.



Here are the kick plate panel supports. They were glassed before installing the panel.



We also built the rear panel, which will consist of 1/2" coosa with 3" strips of coosa running width wise. There are 2 layers of cloth between the layers, and one (so far) on the 3" strips, as well as one on the fillets. Ill snap another pic later to help show what I mean. The top will get several layers of cloth, and at least one layer of mat. Even with no glass on the top side, it seems to be pretty solid. It has to be, as it will need to span the full width of the bilge.



Here are the supports it will sit on:



There will be some 2"x2" angle aluminum screwed to these 3/4" supports, so the panel will sit on 2-3/4" on either side.

The extra order of foam showed up this week, so I finished filling the air box, then ground it smooth and bedded the top and kick plate panels onto it. I taped it all in last night- no pics of that yet. The kick plate has 2 layers of glass on the back side and the top has 2 layers on both top and bottom. This should help screw retention for accessories, carpeted panels, etc.





I filled the gaps around the pipes with thickened resin. Ill be going back and 5200'ing them as well, for good measure. I also trimmed the inlet to the batt box, so here's what it looks like (prior to final painting):



Last night we got the engine assembly started, so the cam is in and one head is on. We measured our pushrod lengths and will get those ordered up today- hopefully we're looking at a launch sometime next week.

WOW! Fantastic job Tim! I can’t wait to see it finished up and on the water…

Have a great holiday weekend!

I guess just a little more than Stock lol

if you could only see the swim platform gary Blackburn handcrafted for me

Haha, thanks Eric!

almost two weeks and no updates, is everything going ok Tim?

I think he's stuck on getting the engine back together. Maybe we need to send Chris east to help out!! He'd have plenty of "Timmy" comments!!
Tim,
Yes, what is going on?

BTW, Roger was absolutely amazed with the Coosa board samples he saw at GL. He being such a freak on composites, he wishes it was available in the UK. It is nice stuff!!

no Tim doesn't like fine details or quick easy proven methods or snap-on tools and I really wouldn't like to slow down an wait for him to catch up and over analize any issues.

doubt that I've been a product designer for almost as long as you've been alive. I've been paid quite nicely to make someones idea a reality, showed the proper manufacturing methods and techniques to accomplish the task at hand and meet all design requirements. But hell any one can design ignition systems, human implants and fighter jets, Hell whats a little cosa board compared to carbon fiber, and titanium childs play actually, but hell he's never been apart of record breaking speed setting vehicle, repeated Indy 500 winning engines or the latest aircraft engine technology that powers stealth aircraft that don't need a runway, so yes it would be a major step down for me and quite simple actually but EE's seem to know it all but always have to have a mechincal guy pick them up after they fall over the hurdles in front of them. Lets over analize how to create a lip to mount a board. please you don't have a clue what my skill set is, because I'm not quoting from a book or online source, it's from experience that you don't have.

...and you dont know mine, either.

All I know about your skill set is what I read on here, and what Ive seen with my own eyes.

Thanks for the offer to help turn wrenches, but I think I'll pass.

sorry never offer too help Timmy.

and yes I did see you struggle with a very simple task so from a design stand point your very weak in that skill set, It's not hard to copy something that is all ready done or you take apart much more difficult starting with a blank sheet of paper like I get paid to do every day.

If you think that the rear panel support was the most difficult aspect of this design, that really shows a basic lack of understanding of what is involved in this sort of project. I guess I shouldnt be surprised, as youve never undertaken one yourself- and that would explain why your input was way out in left field. Another example of our resident Keyboard Cowboy.

As far as "copying" everyone else, Im not sure I follow. Yes, I leaned heavily on those who have come down this path before- specifically Joe with the Coosa, and the other BFN owners who have turned out some beautiful rebuilds. I think it would have been foolish to ignore such things. However, if you cant identify the unique aspects of this design, then there is no hope in explaining them to you. In the meantime, you can keep on producing "brilliant designs" on your blank piece of paper. I assure you that I will be no less satisfied with the results of the final product without your input. Besides, Im just a hobbiest working on a little father-son project, here.

I love a know it all because I never have to say a word. Boo raka shaka Bumbaklot
