Re: Monte Carlo coverboards

Wow, Steve & Roberta, major help, thanks. Love both of those joints! I'm designed for 1/4" cover boards, but Think I can still do plugs, which I prefer. I think the widest Sapele I can get is going to be 12". So, for the bow piece, I'm going to try making a 24" wide section by edge-joining two 1/4"p...

Rudder authority

I'm building a Monte Carlo, which is a 24.5' boat in the plans. I have stretched it to 27'. The rudder is the one the plans recommend, from Glen-L. But when I look at it, now that the boat is almost finished, I'm wondering if I should have shopped for a bigger one. The reality is, I will put the boa...

Re: Monte Carlo coverboards

Wow, Peter, that's one BIG board! I haven't been able to find Sapele that wide, although I think I can get 12" 4/4 by about 12'. The "butt" I was talking about was linear, ie, side-by side. I have done some of this and a careful seam with the grain from the same board is almost undetectable. I'm thi...

Re: Monte Carlo coverboards

Thanks guys, and for the pics. As I said, my cover boards will be 1/4", but nonetheless, I am unable to find wide enough Sapele to make the bow curve in one piece. Even if I could, the largest band saw I know of here is 16", so that would be the limit of the width, if I could find it. I can get 10-1...

Monte Carlo coverboards

I've searched the Forum, but none of the discussion talks about cover boards on top of ply subdeck, or how to make the curved boards for the bow section. The Monte Carlo uses a full 3/8" ply sundeck (all the way to the shears), with 1/4" mahogany on top. If the cover boards are to be like 5-6", keep...

Re: attaching ply subdeck

Yeah, it's a good feeling to know there is metal in the boat taking up the shear stresses. I like the idea of a few screws and then nails. As I thought about it more, it doesn't really matter if there are some slight imperfections in the ply from nails pulling it down into slight imperfections in th...

Re: attaching ply subdeck

Thanks for all the replies on my Monte Carlo question. I have also read elsewhere that the nails/screws serve no function except to hold the ply in place while the epoxy cures. The reason I thought of using #6 bronze screws instead of the nails is that screws give you some control over the squeeze o...

attaching ply subdeck

I've faired the supports and fitted the 3/8" ply subdeck pieces. I plan to use 3/4" and 1" bronze screws and epoxy to install the subdeck. What should be the spacing along the battens, frames and perimeter? #8 screws? Maybe 3" apart?

Re: prop shaft engine flange

The bushing is a great tip I will use. However, it would be difficult, but not impossible, to pull the shaft out and use my drill press to finish it. The flange is set on the shaft using heat to expand it, and the engine is not in yet (so I can't use the engine flange as a puller). Once the engine i...

prop shaft engine flange

I have the engine end flange on the shaft, with the key in place. The flange also has two large set screws. My understanding is that the set screws are mainly to keep the shaft from departing when in reverse, and that the fit of the flange bore and the key are what transmit the torque. My plan is to...

Re: Twin Fuel Tanks - 4 Way Valve Installation

Thanks. I can understand the USCG reg, which has to cover a myriad of situations and boat sizes. I would definitely be worried if it was hard-plumbed. But I have had a hose cross-connection on my ancient Land Rover ambulance for decades and it works just fine. On this boat, the lines and T are well-...

Re: Engine mount "bedding"

I have a support in the way, so it will be two halves on each side.

The trans came on the Ilmor 430. It is a ZF. The mounts are almost level on the stand, with about 2" of travel, so plenty of adjustment.

Engine mount "bedding"

I think I've got the right terminology here, for the wood pieces that are bolted to the inside of the motor stringers, upon which the actual steel engine mounts will sit and be secured to. They are to be bolted through the stringers. "Bedding"? Whatever. In any case, I think the standard is White Oa...

Re: Twin Fuel Tanks - 4 Way Valve Installation

Is there anything wrong with cross-connecting two tanks? I have brass T at the keel, fed by each tank, and supplying the engine. Shouldn't the two tanks equalize with the engine off, even if they don't draw equally while it's on? My fuel gauge switches from one to the other.

Re: Hull Identification Number

My boat is going to be in CA, and when I went to register it, they did want "every receipt", so I departed empty handed. I'm going to give it one more try with the major receipts (which I will have to regenerate). As far as the HIN, I will have to get that first. Apparently the process you describe ...
