Hi Steve,
Man are you making progress! It took me a couple of years to get to that point.

Attached are a couple of pictures that might help you on the planking. My planks were approx 5' long, the ones staggered on the ends were 2 1/2' long. I figured that on the original boats, that the butt joints would end on or near a frame. The my joints are staggered like a brick wall. The butt joints on my boat are parallel to the frames. It you look at the pictures, you will see blue lines. Those lines are where the but joints are. I used screen molding to make the curve and line up the division points at each frame. I also used the moldings tacked in place on the line to scribe the cut for the plank. It worked good for me. I was afraid of using a router to cut the curves. Instead, I marked the cut, got close with the band saw and finished with a block plane. I didn't fill the joints with wood filler because I wanted the joints to show like on the original boats. I was afraid that if I filled the joints, it would look like a big piece of formica.

The screen molding was tacked on the line, a second molding was tacked against the first molding. The first molding was removed, and the compass was run against the outer edge of that molding to mark the line on the mahogany.

The blue lines are where the butt joints are. Notice they are parallel to the frames.

with the help of so many I am now staining and about to buy a bunch of epoxy to wrap this rascal!

I have an engine question. I have my full scale engine drawing and have been chatting with some others who are doing the same. But that PCM 343 engine is going to be a tight fit (touching both the keel and having to take out significant amounts of frame 3 just under the deck.

What I'm wondering is why couldn't I use the 8deg down angle tranny? It sure seems to give me quite a bit of room without invading the cockpit.

Thanks in advance and I will update some pics very soon.

Still having a blast!

There is no reason not to use a down angle gear. It was once hard to find a 1:1 ratio. But, they're out there now. Even then you can use a reduction and increase the prop pitch.

I used a 1.23:1 down angle on my Tahoe 13x16 prop.

Thanks Bill, I'm being quoted the 1:23:1 for an additional $525. I may go that option as it really makes a much easier fit without modifications to the frames and the motor is almost level with a 9 deg down.

I sure appreciate the feedback.

Hi Steve,

You’re doing a great job. I joined the forum a couple of months ago when my Tahoe 23 got started and had lurked for years while planning to build a Barrelback 20. I missed your earlier posts and got caught up today.

A while back you asked about the waterline and I think the answer could use a little more discussion. Please see page 5 of the instructions “Boot Top: This is a painted line normally considered the waterline…locate the top of a 2” wide boot top strip 2” below the set up level all around.

I think mine is the ZF-63a. A 1:1 gear w/12" prop is equal to 1.23:1 w/12"x1.23=14.75" or 15".

firstly, thanks to the folks who take the time to respond to my many questions. Unfortunately those responses have spawned more questions!

TomB - I'm sorry, I can not find the link to the page 5 you referenced. I have searched for "boot top" and "page 5" and don't get any solid results. however I think I get what you are saying but would love to read the referenced material.

Bill Edmundson - If I understand correctly, a 1:23:1 transmission turns more slowly than a 1:1. there for are you saying with the same pitch prop I would need a 15" prop?

again guys, the help and responses are so appreciated!

Steve

I have another question regarding use of poxy seal. I have about a half gallon left and believe I can use it to seal the mahogany planks that have been stained. I believe that it is a good use of the poxy seal (vs CPES).

Thanks in advance,

Steve

No. Not more diameter, More pitch.

thanks Bill, not only does that make more sense, I like it better because the prop will fit!

Hi Steve,

I was referring to the Barrelback written instructions that came with the plans. The heading for Boot Top, on page 5, is where KH addressed the waterline.

Hi Steve,

I can confirm that TomB is correct as I have the same instructions for my Barrel Back concerning the boot top or water line.

Martin.

OK TomB and falconer100, you'd think after reading those durn instructions 10 times I'd remember that, but when you do it so long ago and learning so much before doing anything, I forgot about that paragraph! anyway, I've come a long way and not been very good at posting pictures, so let me play some catch up.

Here is some stain going on.
