Jedo's Volero Dart Resto...

Re: Jedo's Volero Dart Resto...

"The stiffness and rigidity of the stringers is supplied by the FG encasing the stringers... some manufacturers use hollow pre-formed box construction FG...
No Timber is guaranteed to be completely resistant to the effects of water, over time... (some timbers are less-resistant than others)
Given that the viable lifetime of the restored Volero is a possible maximum 10 yrs (if it floats at all) the choice of timber / material for the stringers is less important than the protection affordedby the applied FG..."

The above is certainly true IF... you apply enough layers of glass and extend the tabbings appropriately onto the hull to carry the stresses placed on the hull. I would suggest a minimum of 4 layers of the CSM and the 1708 type cloth.

Re: Jedo's Volero Dart Resto...

Hi woodon...
As stated - I can't source 1708 in Australia... but I will be using at least 4 layers of 600g CSM...
The stringers will have some kind of timber core - ATM I'm thinking Meranti / Luan, but if I can't source the 11ft lengths required then it will be seasoned DAR plantation pine...
What width and length of tabbings do you recommend - and spaced at what interval...
Thanks for your help

Re: Jedo's Volero Dart Resto...

Looks like your making some good progress ! The stringer I would think should be placed where the original ones were placed .
Btw , you may have to rename her Itchy Everywhere after all the grinding !

You can 'make' longer lengths of stringers from 'normal' 4X8 sheets of plywood. Luan typically doesn't have a substantial core, unless way over there Luan is a somewhat different product then the lightweight, usually 1/4" underlayment, that it is here.

3/4" ply can be scarfed to make longer lengths, or you can stagger the joints & laminate two 3/8" sheets into a longer 3/4" thick piece.

As SP suggested, using the original layout for stringers would be preferred. Unless your question was about the spacing between pieces of tabbing....

In which case, tab as often as needed. Stringers that are an irregular shape, sharply tapered, 'tall' or that intersect bulkheads, chines, gas tank compartments & etc may need more frequently spaced, shorter length (along the stringer) then stringers that start out at the transom & evenly transition towards the bow. Taller stringers will need the tabbing to run up onto the stringer further & out on the hull further as well. The tabs are often done in 2 layups, once you have a support system in place to hold the stringer where you want it while you bed the stringer, some tab at those locations as well before removing the supports. Then remove (reposition if necessary) the support system and finish bedding & tabbing the stringer where there was none (at those support locations)...

The tabs are solely to attach & hold the stringers in place until you can fiberglass them to the hull.

Read thru some resto threads. It was surprising how many boats had seemingly random. haphazard(sloppy even) construction below deck. Many look to have had heavy woven roving saturated w/ resin & merely draped over the wooden stringers occasionally along their length. No other fiberglass work done to hold them to the hull....

Re: Jedo's Volero Dart Resto...

why not just use structural/marine ply...properly glassed in etc etc.. for the stringers?
did the original stringers stop at the front bulkhead and then another section from there

why only 10 years?
it looks to have been made between '68-'78 and looks to have had the original floor and packing material between the hull and deck,
someone else will still be using it down the track for awhile yet,
lots of early FG boats from the 50's...and earlier..still being used

I should have added, that doing the stringers this way ^^^, is insufficient & may 'only' last the 10yrs you mentioned earlier.

Following WOG's advice @ layup schedules & details in his signature link for stringers, transoms & decks, will give you a much much longer service life from your Dart......

Re: Jedo's Volero Dart Resto...

Thanks for all of this great input and advice...
*sphelps - Renaming is a must..!! Keeping with the maritime theme, we did think of renaming her "Itchy Groyne"... LOL...

Stringers: Yes... I do see the importance of glassing the stringers properly and effectively and that's the way I'll do it... The "core" of the stringers seems to be a less important consideration so I'm not overly concerned what timber I use there... Hardwood would have been preferential over softwood (pine) and I'm still leaning towards Plantation Mahogany at 35mm thick...
My thoughts are: measure/cut/shape/dry-fit each stringer. Then wet each one out thoroughly and glass over with my 600g CSM before bogging-in (PB), tabbing and glassing each one individually to its allotted place in the hull... I'm also adding 2 'extra' stringers to each side of the boat so as to raise the deck (previous deck was just resting on the flat parts of the hull)...
Given my tendency to "over-engineer", there will be quite a few layers of 600g CSM individually applied to each stringer - and not merely draped over them...
I'm waiting delivery of Gelcoat to complete the underside of the hull before turning to the stringers...
Thanks for your continuing help...

Jedo Velero Dart Resto2

We had a hiatus in the Resto since my last post in March 2013 - combination of Winter, Holiday Trip, and Illness...
Nothing at all done to the boat since that post: http://forums.iboats.com/boat-restoration-building-hull-repair/jedos-volero-dart-resto-594388-2.html
A banner on that thread advised me to start a new thread as that one was over 90 days old
So... Here she is:

Awaiting application of flowcoat/gelcoat on the repaired hull (which I now have)
Can members please advise re 2 questions:
(1) Do we need to flowcoat/gelcoat the whole hull..??? Or do we only need to flowcoat/gelcoat the areas repaired..??
(2) I'm not confident with a spraygun: Can we apply flowcoat/gelcoat with (a) a Brush, (b) a paint roller..??
Many thanks for your advice and thanks for advice already given.

Hey Jed, that red banner is just to keep other blokes from bumping the thread to the top in case you aren't around anymore. You can reopen this thread any time you take a notion to.

You can just paint those patches if you want, but they'll stand out... depends on how pretty you want the boat to look. If you want it to look pretty you need to paint the whole boat.

Re: Jedo's Volero Dart Resto...

Thanks 'jigngrub'...
Well, I'm keen to get the job done and see the boat back on the water for the G'kids. Seem's easier to bodge-up the bare fibre glass patches with the gelcoat/flowcoat and then smooth all the patches back with wet'n'dry, than to strip ALL of the remaining gelcoat off - and then recoat the whole lot...
Thing is - will such a "patch job" make the boat water-tight..??
My skills at boat-repainting are minimal, so there's no guarantee that a whole re-coat (by me...) will look "pretty"...
I practised brushing it on (small area) and was dismayed to see all the brush marks... Rolling it on just gave me a landscape of peaks and pits... Overcoating the whole hull would be a nightmare to sand smooth...
I'm a little more confident about working on smaller areas - provided that method keeps the water out of the boat.
Just like fixing a "ding" in the hull - except here we have 5 or 6 "dings"...
Anyone's thoughts are more than welcome...
Thanks

If only I was an ace with a spraygun...

I have to agree that she has an attractively curvaceous bottom...:laugh:
However... she is rather plain above the waterline...:lol:

Re: Jedo's Volero Dart Resto...

Paint on f'glass is just "fluff" and "eye candy", if you did a good job patching the hull with the f'glass your boat should be waterproof.

As for applying the paint, you just need to practice before you jump on that hull. If thinned down properly the gel coat should roll on properly and look good enough. The same thing with a spray gun, practice.

Here's a thread where Trooper futzes around with some gel:
http://forums.iboats.com/boat-restoration-building-hull-repair/78-ebko-lebaron-therapy-524704.html

... and Decker does some futzing with it too in this thread:
http://forums.iboats.com/boat-resto...om-deck-stringer-replacement-help-471173.html

I would strongly advise against grinding the old gel off of your boat, it's more work than it has to be and can look pretty bad if you don't get it just right.

Maybe some of the paint gurus will stop by and give you better advice than mine.

Hi 'jigngrub' - thanks for the extra info:

I'm thinking another layer or two of FG & Poly to build the hollows up before flowcoating...

I'm going to try the rolling & tipping method and see how I go with that... Since they are only 'small' areas (compared to the whole hull) then sanding them back won't be too arduous...

Re: Jedo's Volero Dart Resto...

Some progress...
Gel-coated the entire hull using roller x 5 coats: no wax.
Light sand with 150 over last coat to knock off the nubs.
Have now applied first coat of putty-filler.
This went on smoothly with a roller.
Hot weather now upon us - 38C - and blistering sun, so will have to wait for a break in the heat before applying more coats...
Have still to replace the stringers and transom...
