Still at it!!

[landrover]

Hello All,

Might get it in the water yet this year! that's the goal. Just wanted to post a few pics and ask if i'm on the right track. The shots of the keel are of what i hope is completion! Keel laid into Pl premium adhesive, 1/8 gap at min,then a 2inch strip csm in the corner, then a 4 inch, then 8 inch, then a full width from side to side with 1708 stiched cloth. Is that enough? Hoping so. As for the other pics, that's my rebuilt transom from the inside. 2 slices 3/4 inch ply as was there before. Should i add 1 more 3/4 ply? 115 hrse yamaha is doing the pushing. However i really have to "nail" down the gussets. How thick? Do i use 3/4 ply doubled up as well? How do i attach them to the transom(should i screw them to the transom first) should i also tab them in to the rear deck?How many layers of 1708 should i use to ensure the strength and stability so there is no more flexing at the transom? Do i transition to the floor the same way i did the keel? Thanks for any input,

Landrover

Re: Still at it!!

Great job everything is looking really good and from what you are saying you are definately using the info from the pro's on here to correctly restore your mother ship.

I am only giving you some idea's of things and ways that you can attach your gussets to your transom. You can lay fiberglass in conjusnction of epoxi, use dowels or dog biscuits as well as epoxi and fiberglass.

As for the thickness of your transom, what was the thickness of your origional transom? What was your boat certified to carry on the stearn? If you are moving up in weight did you add anything or is the thickness you have now mirror image the origional? If you do have to add size weight and thickness is anything going to hinder from putting the boat back together?

Re: Still at it!!

ok....a few thoughts....

1. in pic 3 there is chip board in the boat......get rid of it. use proper ext ply.

2. in pix 2 & 3 there is woven roving...is there csm under it?...or is that factory?...it needs csm under it or the bond will not hold...if its factory....its fine...forget it.

3. you need to cut a better angle on your "knees" to the transom.

4. make sure there is a layer of glass between the transom and where you join the "knees" to the transom. (that way if one peice rots....the glass will prevent transfer.

5. once the gussets ("knees") are placed in the boat...you can pl them in....wait till it cures...then just glass over it in a tabbing fashon to the transom

you are a ways away from the water yet...but not far if you have the time to spend on the boat.

cheers

Re: Still at it!!

Have I missed something?? Is it common to lay fiberglass cloth(csm,etc.)over the floatation,stringers,etc.prior to installing the deck?Or does it just look like foam in your pics.

Re: Still at it!!

Hi Guys,

Thanks for the replies. But my heart did sink Oops, when you mentioned the roving. When i ground out the original glassing due to the rot, it seemed a little thin in the chines, so i happily laid down the roving thinking thickness build, no csm underneath. Low and be hold, i've bonded my 1708 edges to it.

Should i grind out all the roving and just add more 1708 ?

As for the particle board, it was my "bench" for my waked paper so i could slather on my west system.

As for the angle,what shoul i be aiming for? The angle that you see is from the old gussets end point, so i matched up for the new ones. From the bootom of the transom to the tip of the old. Should i be beefier or more shallow?
As for the flotation there is none inher now,i removed it all. That's the stringer, which is a 3 ply of 3/4 inch marine ply, glassed over for strength ,stability, and rot. My impression from all the reading i've done here is that it is a safe practice to do so.And mine was done from factory, so i'm returning it to spec.
Thx

Re: Still at it!!

rover...resin by itself is weak. very brittle....check the pot you mixed your resin in....see that thin film around the sides of the pot...you can crumple it up in your hand.

when you lay a roving without csm down...you get a resin rich area between the substraight and the roving....the resin rich area is as brittle as the stuff you crumpled in your hand.

csm is used to build bulk with not much weight and also to absorbe any extra resin.

the roving you layed...with out csm between the substraight you might be able to pull it up with plyers.
the 1708 if layed with the csm down will not be affected.
if you cant pull it with plyers...out comes the grinder bud.

as far as the angle on the gussets (knees) just have the angle match the hull transom angle...thats all. so the knee touches the hull the full legnth and at the same tinme touches the transom.
just remember to seperate your transom and gussetts with fiberglass...that will be a rot barrier

 

[oops!]

Re: Still at it!!

WAIT..... is that epoxy you are using??....

if yes....dont worry about the resin rich area....epoxy is not ment to be used with csm. roving can be layed directly on a substraight with epoxy resin.

Re: Still at it!!

Thanks Oops,

Sadly that roving was put in with vinyl, then i swithched to epoxy. Just to difficult to breathe with the vinyl stuff. AAargh! though , i thought i was done with the grinding. Or is there a chance that with what i have laid down all around it , and the fact it was only the last of the three layers that are on it that the rest will hold? I first pl'd the keel in , then a 2 inch corner strip csm, then a 4 inch 1708, then an 8 inch 1708, THEN the full width laying on the roving. Is it possible that those first layers will hold it in place. It's a 16 foot cvx carlson with a 115 yamaha pushing,hoping that it will be small enough that you'll say that my last layer was overkill. As for the angle i cut on the gussets, i'm hoping it might be a little overkill so there won't be any flex. The last ones were cut with a curve in them that lessened the angle at the transom, but they flexed alot.
Here's hoping

Re: Still at it!!

yep....youll be fine...

the roving is over the 1708 with epoxy.

just remember that any time you lay down a layer of glass with poly resin (or VE) you need csm between. the 1708 has csm so its fine....the roving is laid with epoxy...so it does not need the matt.

and...lol....yes...thats overkill. one wrap of 1708 over a csm tabbed stringer is lots.

i used more on the hull extension to be sure it was strong enough for the glassed in extension section

Re: Still at it!!

Thx Oops,

But the roving was put in with vinyl, and is the first contact layer with the hull.Then i laid all remainig layers with epoxy. So that roving is vinyl bonded. Do you mean that i'm ok to leave it because of the amount of layers and square footage elsewhere? Or i'm i still going to have to grind?

Re: Still at it!!

As well her is what i was thinking as a beefy gusset. Pl them together,then to the floor and edge of the transom?
As for that roving, here is a pic of the full width of what i have on the floor,can i get away with leaving it?

Thx again

Re: Still at it!!

Any thoughts ,
will i still have to grind?
Thx

Re: Still at it!!

Sorry Oops,

I'm stalled on this rebuild in case you really think i should grind again. The roving was put down with vinyl then epoxy layers over. But with those last photo's , do you think i can get away with leaving it?
Thx again
Rover

 

[oops!]

Re: Still at it!!

yep.....leave it.

the ve and epoxy will be fine.

sorry for the alarm.

there are a few ruls that cannot be broken using polyester resin.....ve and epoxy are a totally different stuff.

 

[landrover]

Re: Still at it!!

Oh god,

Just for the hell of it , i asked the guy who sold me my resin here last year, and it turns out i was wrong. That roving WAS put down with POLYESTER, not vinyl, My apologies Oops, for taking alot of your time.

Must i still grind out knowing the roving IS down with poly, or is it a small enough foot print to leave alone. I'm not overly familiar with those few unbreakable rules.Thx muchly

Re: Still at it!!

Hoping Still!!!

I'm not going to move ahead with the floor until i get confirmation on the grinding, But i did laminate the gussets and they are ready for install.PL in place , one at a time so i can clamp more effectively. Plius that " i don't get it thread" was a real eye opener. Foam will be going back in to this baby! Safety first for the family. I wondered though, has anyone ever laid in a "bag" in which to pour in the foam , so that after it sets, it's encased in the bag, so moisture stays out?
