FL Tahoe 23

Post by djwalsh1960 »

My Name is David Walsh.

I have been following reading this forum for a looooong time and finally purchased the plans for a Tahoe 23.

I have completed the building form and I am busy transferring the plans to plywood to make templates. As I gather materials to continue, I am having difficulty locating stock (Khaya, Sapele etc.) long and wide enough for the motor stringers (16' + ft.). I am wondering if anyone has some thoughts or experience with starting with 4/4 stock, scarfing and laminating to get to roughly 17' long and 8/8 thick. I can cut to length and plane to the width called out in the plans and I will offset the scarfs on the lenghts of stock to be laminated.

Once complete, will I have stringers that are strong enough?

David,
That is what most people end up doing and has advantages of generally speaking a stronger stringer less prone to warping.

Thank you, Tony!

I had another question (of many, I am sure). The plans call for 3" wide stock on the frames unless otherwise noted. I assume that means that the width where floor members join side members is 3".

However in following your build and reviewing as many photos as members post, it appears that the widths at those junctions are far more than 3". Am I seeing things or are the frame members really 3" at those joints?

Welcome to the forum David,

The frames are 3" minimum. The bottom members of frame 1-8 are all 3". Also have a look at the Frames Drawing, Sheet 2. For example, frame 1 would be 3" at the chine and sheer and wider in the middle.

Hi Tom,

You have made it perfectly clear. I re-reviewed the plans and it's starting to sink in. I appreciate your welcoming the newcomer. I have been gobbling up information from everyone's posts and pictures for months...well...years. I feel like I know you all and I look forward to a great adventure.

Thank you, Tom.

Well, I have scarfed some Sapele stock together to get the correct lengths for the stringers and laminated the finished boards together to get the width needed. This weekend I will shape and notch them per the plan. The scarfs look really even and tight. I offset the scarfs when laminating so that they do not lay on top of one another. I fabricated a jig for my table saw and with a little trial and more than one error, I was able to cut duplicate scarfs on each length and they came together like pieces in a jig-saw puzzle.

I would like to add a really boring photo of a very long board with a bunch of clamps, but I am struggling with figuring out how to upload. I have a way with computers you know... However, I am making progress.

I was fortunate (lucky really) to find 20' Douglas Fir beams from a local supplier for my 21' build. Scarf and laminate away if it's the best you can get, it'll be plenty strong.

Hey Bluseman.

Someday, my workshop is going to look as organized and SPACIOUS as yours. The scarfing and laminating will create some pretty sturdy stringers. Now, I just need to figure out how to post photos.

Hi,
There is several Tahoe builds at the Gatherings.
The Gathering is a fine place to share build processes and build tips, and, boat rides.
Would like to see new builders there, a fun time.

Making Progress

Post by djwalsh1960 »

It's going slowly but making progress. The stringers have been laminated, scarfted, notched and encapsulated. Frame 1 is finished and Frame 2 is nearly ready. The Fastening Schedule for the Tahoe calls for 1.5" screws to secure the frames to the deck beams. However, I have seen a number of photos of builds where carriage bolts were used. Would it be better to add a couple of bolts per frame member?

Bolts at the deck beams? No, I'd use the 1 1/2" screws. The only place you need bolts are the junction of the stem to the keel and at the blocking for the motor stringers.

Hi Roberta and Bluesman. I appreciate it. Looks like screws will work and bolts where the decks and frames join will add some strength. The stringers are laminated and scarfed. If you zoom in on the photo, you will be able to see one of the joints. 1.5" sringer width calls for a 42" scarf....that was fun! All joints have been epoxied along with fasteners. The stringers ( and now, Frame 1) have also been encapsulated in epoxy.

I miss read your post and was thinking frames to clips and stringers. Bolts are appropriate there. Screws and glue are fine with deck beams. I deleted my post to avoid confusion.

I wouldn't use any bolts at the deck beam connection on the frames, you'll need to notch these corners later for the sheer / deck clamps and you'll want the bronze screws as they'll easily be cut if you need to (you will cut into one sooner or later, trust me). Plus the size of a bolt hole here would create a weaker joint, not a stronger one. Epoxy & screw these connections.

I'd stick to the instructions.
