Nice looking work...i think ....all the aluminum is causing me to loose my memory

So how are the aluminum braces attached to the hull / deck? Transom looks stout!

The single stringer that goes to the box (bilge) ....... I added ad additional laminated piece or 3/4 to each side and drilled through. Bolted the braces at the bottom and ran them up to the aluminum channel brace across the transom. The aluminum brace is bolted to the transom in 4 places and the bolts were bedded in with epoxy. There is a 2x3 laminated under the aluminum channel attached to the transom.

Think I need to get some more epoxy too. My friend brought over a whole roll of 17 ounce biaxial fiberglass cloth....... the roll is easily well over 250 pounds. Really nice stuff and I will use it to cover my deck.

AlumaGlass!!!!

Be prepared. 17 oz fabric will soak up a lot of epoxy, and IMHO is way overkill for a deck, but since it's FREE (The best kind of fabric) you can't beat it!!!!

I agree! But........... I was swayed by the price

Being a C.O.B. I completely understand!!!!

Re: Sidewinder (Cobra) 16 SS

Had some time and a bit of nice weather. Got the deck tabbes in using CSM and 1708 3" tape. I ordered more epoxy before I finish the deck.

Here is a shot of the tabbing - there is a layer of csm under the deck, over the joint and a layer of 1709 cloth. I doubt it will let go.


Here is a shot of the knee braces that show a bit of the angle. The wood received more epoxy and fiberglass today too.



Now here is the challenge........ the boat was re-painted with a very durable paint over the old gelcoat and metalflake. I imagine the gelcoat and metalflake were cracked and the finish was poor.....well someone did not do enough prep and the cracks are showing through. I have a feeling I have a tremendous amount of sanding ahead ;( All the top surfaces (facing the Sun are this way.

Re: Sidewinder (Cobra) 16 SS

Yeah, I'd say a good Respirator and Lot's of Sandpaper are definitely in your immediate future!!! As we all know It's ALL about the prep!!!!

For a "Tinner" you're glassin looks purdy darn good!!!!

Re: Sidewinder (Cobra) 16 SS

Looks like you have some sanding time. A good pneumatic dual action sander will make life a lot easier. I have a 3m foam pad on mine, its about 3/4" thick and softer than the ones that come on them. it does a nice job of conforming to the curves of a hull. You can get hook and loop, but I used the 6" sticky paper, its usually cheaper. You do need a pretty good air compressor however....those things love air! Nice looking work, you are making quick progress!

Re: Sidewinder (Cobra) 16 SS

Looks good and done fast...glassing quality is top notch...
Very interesting "composite structuring"...I like it!
Happy Mid-week!

Love seeing someone work on these boats. Gives me some fuel to pull mine out. She is an 18 ft jet.

Those are stainless steel bolts that were epoxied in to the cross beam and the beam was completely sealed and epoxied in and the aluminum is 1/8" thick. It was actually aluminum I had left over from doing my Starcraft SS.

I am hunting for a "large" motor and last night I missed out on a 175 Johnson on craigslist which went for $800. I am patient for a 150 or larger otherwise I do have a 115 in storage

Re: Sidewinder (Cobra) 16 SS

Just have to vent....... I am on a sightly overbuild mentality but did not think the spashwell through......... now I am in the process of correcting my errors.

My transom boards are laminated with csm, the transom was glued to the hull with csm, the spashwell was glued to the transom with csm everything being done with epoxy. Well I glued the splashwell and had to slice the splaswell to remove the 3/8" of overage I created.

Yup had to cut the splaswell all the way across and now I am in the process of re-attaching it with more csm, epoxy and fiberglass. It is working out but a comment need to be acknowledged - archbuilder is right I have done a few fiberglass hulls before and the epoxy is too time consuming....... however...... stronger then hell! Incredible working time...... even during 90 degree days.

I will get some more pictures up soon but only have been devoting about 2-4 hours a week to the boat. Since our season is soon to change here my next goal will be to flip the hull, work the bottom and probably leave it flipped all winter. I still have my Starcraft to play with.

Re: Sidewinder (Cobra) 16 SS

That sucks, but that is the way it goes! I don't know how many times I have measured twice and still cut twice! Poly's speed is a double edged sword.....you end up working like a mad man sometimes trying to get everything placed before it fires off! Good luck with the fix!

Re: Sidewinder (Cobra) 16 SS

:grumpy:Epoxy top and bottom and of course............ I am waiting for it to dry....

I guess I will work on my Starcraft in the interim.

Re: Sidewinder (Cobra) 16 SS

Looks like a nice job stitching the pieces back together:thumb:...Once it's all faired and painted, only we'll know it was ever cut apart...

Re: Sidewinder (Cobra) 16 SS

If you don't mind me asking, why are you using CSM with epoxy. Typically you'd use a 4-6oz e-glass fabric with epoxy for this type of repair.

 

[Bob_VT]

Re: Sidewinder (Cobra) 16 SS

The epoxy with csm fills the gaps and is super strong. I used light cloth too but csm is my favorite "glue" material between things.

Another key with epoxy is not to over-clamp and squeeze things out. I have used cloth BTW the csm behaves very well with the epoxy

 

[Woodonglass]

Re: Sidewinder (Cobra) 16 SS

Hmm, due to the random loose strand make up of the CSM it really offers very little strength to the mix but... with epoxy having it's own binders it does not require a lot of added "Flex" strength soooo, if it works for you more power to ya!!!! I've always used 6 oz fabric and it also works well in filling gaps, bridging joints and is easy to use and will conform to just about any shape. Epoxy is great cuz you can use about anything with it and never have a failure!!!

Re: Sidewinder (Cobra) 16 SS

Took the Sidewinder out of storage and getting ready to dive back in. The hull had been painted before but the bottom of the hull has the old metal flake........ feels like 100 grit paper if you run your hand over it. Now to dig out the sander.
