You most certainly can.

OK Jono.
I have tried to track down 10 x 5s in 18mm and failed dismally. 4,5,6,9,12 mm available by the bucket load but no 18mm.
Who do you suggest?

[nugent]

try here Mark, we have had them glue up specials for us also in the past. for large bill board signage

Thanks Nugent
Again only 8x4s in marine ply.
I can scarfe boards together myself. Its just that the deck is 5' wide over the back 10' and the only cut is around the well.
The more I look at it the more I am thinking 3 off 8x4s will be a better idea.
There are no ribs or frames aft of the anchor locker. I think I would like a bit more support latterally without relying on the deck.
If I use 8x4s, with 3' cut off the end, I can put a bulkhead under each join.

[Jono]

As Nugent said...I got mine from Birmingham board ...aka Arnold Laver. Have you rung them? I had mine about 3 or 4 months ago on quite a quick delivery from what I recall.. Just getting my "boy" to give 'em a call....

<edit> Oops ! Duff Gen..sorry. What was ordered ..by me..and what turned up didn't match, but the boys "on site" cleared it with the Site Manager...who seems to have overlooked the fact that I had specified Marine which i am just off to discuss with him.......it turned up as WBP NOT Marine... best look at the invoice carefully now.

[Mark Halliday]

Cheers Jono

I hope the invoice is for WBP or you will be after a BIG refund.

I have just had a meeting with the co-owner and we have decided to go the 8x4 route with additional bulkheads and stringers. To hell with the extra weight. It is one way of using up nearly a whole board of offcuts.

I have been quoted £59.79 / sheet, 1220 x 2240 x18 marine ply by my local timber merchants, which seems a reasonable price.

[Jono]

....so having "gone off on one" at the Site Manager… he doesn’t bat an eyelid and (imagine a heavy Black Country accent) calmly says… “ I told the lad’s it’d be alright…coz the Gaffer would know that Marine Ply don’t come in 10 foots… and I didn’t think you’d want to look like a c**k having ordered the wrong stuff…”………. Ho- Hum…

Hmm, a deck with no console, thats looks familiar Mark

However whats making me slightly nervous is the Tohatsu was built by the same firm and its had lots of water over and under it.

You don't fancy taking the engine and tubes off then glassing right across the hull ?

[Hugh Jardon]

That might explain it then.

Marine ply is WBP but made from higher quality timber with no large knot repairs and no voids.
Good quality faced WBP is probably reject marine stuff.

Why's that then?

Mine has a slightly chequered history. I would not like to say that mine was constructed to the usual standard.

NO

[Mark Halliday]

Progress to date.

The floor came out remarkably easily with a little help from the old scottish screwdriver, aka angle grinder. I can honestly say it is not a job to do on a hot day. That dust really sticks to sweat.

It now looks like the port deck bearer may have been contaminated when fitted back in 1997ish. If that is the case, I think the whole thing has held together supprisingly well. Admittedly I would have prefered to find hardwood or ply - BWMs were known for being cheap.

1) Rear deck cleared and tank exposed (53l of liquid gold removed).
2 & 3) Port $ St'bd deck bearers (port to port etc)

[Mark Halliday]

Well that about it for the demolition stage.
The tank was bedded in with filler , and required a bit of TLF with the crow bar.
I am going to try to peel the tube tape off the inside of the hull and drop the tubes outside and below to keep them out of the way. If that fails, I will remove them completly.

So why did it happen?
Cheap build spec. is mostly to blame.
As far as I can tell, the port deck bearer was contaminated with rot before building. These bearers wer secured to the stringers with a mixture of St/St screws and mild steel screws (they may have been very poor quality St/St).
The soft screws rusted away over time allowing the rot to escape through the resultant holes. The floor was not well supported and flexed, resulting in the resin coat on the underside to crack. The rot then entered the floor through these cracks.

[Pete7]

That looks better, is it worth changing the fuel tank sender whilst it's easily accessable. I think they were tempo items and when I tried to change mine in January for another 5 bolt one the holes didn't line up. Oh and then the chandler told me Tempo had gone bust and the importer couldn't help so put the old one back in.

The question is who has less work to do for the RB Powerboat race start in 8 days time, you or John Fuller

Pete

[Mark Halliday]

Pete.
Thats good advice, except the sender is purely there sto stop the fuel getting out. The gauge used to flap about so much it was useless, even on dry land. Unlike most, I seem to have an acurate Navman 3100 flow meter.
Just in case I change my mind, I will be putting a hatch back over the sender.

I like that one.
