banshee transom and likely stringers

[banshee owner]

GT i was leaning that way too.

How much bigger did you drill the holes for peanut butter they look 4 or 5 times bigger from your pics

 

[GT1000000]

For the stern eyes I did make them about 4X bigger...let me think...yeah, they are 3/8" bolt diameter eyes and I believe I used a 3/4" or 7/8" hole saw...maybe it was a 1"...hmmm...
The garboard plug assembly is approximately 1-1/8" in diameter and I believe I used a 1-1/2" hole saw...
I think one of the reasons I drilled them out so big to begin with was to give me lots of play in the actual final positioning...

well guys its been a long time slowly making progress last night was huge milestone. I finalyy got the carpet cut and fitted and laying in the boat and i must say its loooooookinng goood lol. I also got the seat bases covered and the joints are almost seamless between the carpet on the floor and the carped on the bases. I must say it looks alot better than i imagined it would.

THRU HOLES in transom should I drill em larger and fill will with thickened resin and re drill then use sealer

Yep. With the caveat mentioned by GT1M.

Also, I tried something with a previous project for the bilge drain that I was quite pleased with. I took a piece of plastic conduit (ABS?) and rubbed a candle on it ("release agent"), then set it in PB (epoxy in my case) inside an over-drilled hole at the bottom of the transom. The next morning I gently tapped it it out and had a lovely smooth bilge drain. I chose conduit the same OD as the ID of those brass drain tubes, so the plug fit in snugly.

I chose this route since i have seen many transoms rot out around the brass drain tube set in sealer, which *never* seals.

My before pics arnt that great but they give you an idea how rough the carpet was and dirty

GT1 or anyone else i drilled my holes int the transom and filled with peanut butter i didn't not put any chop strand in the mix just cabosil i found the chop made it stringy and spikey. my problem is the holes i filled with PB ended up cracking thru the muddle and the actually looks like it shrunk and separated from the edges in the hole. Would that be because i didn't put chop in or mixed wrong i haven't seem to have that problem before.

Any insight would be appreciated

I'm also thinking i might try hammering the PB plugs out and try again and hopefully second time they would turn out better

 

[GT1000000]

Yep, without the chopped strands, that thick of a layup will tend to crack as it cures due to shrinkage...
Also make sure you are not over catalyzing...
If your chopped strands are much bigger than say 1/4-1/2" in length, then take a little time with some scissors and chop them up a bit more...
You should not need very much...figure to do 4 stern eye holes at approximately 3/4" diameter by 2" transom thickness, you should only need about 6-8 ounces of resin, approximately the same in volume of the cabosil, and a small hand full, maybe 4-6 tablespoons of chopped strands/milled fibers...mix it all up really well, then add your catalyst.
Even though it is a bit hairy, a quick hit with a D/A and some 24-40 grit, will knock them off...
Don't try to bang them out, you might cause more damage than you want...
It would be best to just drill them out again using the same hole saw as before...just make sure you get it good and centered...

Yeap what GT said. Seems like a lot of people starting out get into trouble using a bit too much CS in their PB when doing fillets so I like Woods recipe of 1qt resin, 1.5qt cabosil and 1/4 cup 1/4" CS which is 2 oz. So for 8 oz of resin that comes to 12 oz of cabosil and 1/2 oz of CS. Good luck measuring that! Oh and I tend to go light on the cabosil like GT said 1:1 is fine but for this I'd probably go thicker. I also coat the bare wood first even with PB.

 

[banshee owner]

thanks guys for the input. i didnt have any problems with my fillets they all turned out good. i guess ill have to drill and redo them which isnt a big deal.

On a side not i have the carpet al glued in and seat boxes covered and ski locker covered.

unfortunatly it would splash this year but i will have it all next summer yippe and knowing it is safe again makes it all worth while

cheers and have a good day

CSF (Chopped Strand Fibers) used in making PB for gluing the Transom to the outer skin should only be 1/4" or less and should be added in quantities of about 1/4 cup per Quart of PB. That should yield a very "Non Hairy" mixture and if you keep the MEKP ratio @ 1% to 1.5% you shouldn't have any issues. You can make your own from scraps of CSM

 

[Daniel1947]

OK Wood....1 quart resin + 1/4 cup of CSF (<1/4") + how much cabosil??? I know it is usually left up to the cook, but what do you recommend for a good normal PB mixture?

 

[Rickmerrill]

Hard to make cookies if you never tasted one. Cabosil at 1.5 times the amount of resin is good for starters.

 

[Daniel1947]

Thanks Rick....guess I am getting old....that is exactly what you said a coupe posts back. I am probably following too many threads. I am so confused. Thanks again...I will read more closely in the future.....yeah! right. :facepalm:

 

[Rickmerrill]

I'm so old I didn't remember I'd said that!

...said what...?

Boat is pretty much done. Will upload pics and this may long weekend it will make its first splash in the lake.
