Still having problems fitting Eastport Nesting Pram


Hope someone can help me -I am still having problems getting the transoms on the Eastport Nesting Pram to fit. I posted here last week and also spoke to CLC and they said that it was okay to have gaps as large as (not bigger than) 1/4 inch at the ends of the planks. I tightened them as much as I could - added more wires near the ends as Terry suggested - and still cannot seem to get gaps from occurring, but they are less than 1/4 inch. So I thought it was good enough. But when I tried to wire in the stern transom, well, there are still going to be gaps because the notches that are cut into the transom bottom and sides will not fit precisely where they are supposed to along the bottom blanks.  Is this OK? Or do I need to get them aligned? Will I be able to somehow get them in the proper place when I turn the boat over? Attaching some photos. The same as is illustrated in photo #2 is the case in the rest of the notched corners/edges.

Thanks in advance!

(1) Shows gaps at end (stern). Similar at the bow. 


(2) Hope you can read the annotation -  it got cut off when I shrunk the photo down. Here it is again "Notch" (in red circle) would end up here (meaning just under the arrowhead) when boards are forced together, not to the left over the lip of the plank.

RE: Still having problems fitting Eastport Nesting Pram

You could try changing the wiring order and attach the planks to the transom first to guarantee that the notch lines up with the lip, then tighten up the plank-to-plank stitching. Or. you could get rid of the notch with a rasp as long as any gap is under the limit for filling with epoxy/woodflour putty. Remember, the strength of the joint comes from the fiberglass tape and epoxy putty fillet, not from perfect mating surfaces held together with carpenter's glue.

I know that this is bound to be frustrating, but it really is a case of taking it apart and trying again until it's good enough for your standards. From a mechanical strength point of view, the fit does not have to be perfect, only fair and symmetrical. From an esthetic point of view, paint and fairing compound will cover a multitude of sins and you can still end up with a prize-winning yacht finish, so don't get discouraged. You will have a fine boat, no matter what.

Good luck,

Hello, try this temporary clamping method to close the gaps in the planks when trying to fit the transom.

Also, tap the wire inside the hull flat before you tighten the wire outside of the hull. That small slack in the wire can leave you with gaps in the planking after you tighten the wires. I also use some 17 gauge steel wire from a previous build. Careful not to rip the wood.

Goog Luck, Capt Mike

   Thanks, Laszlo! I think I am going to go with rasping down the notches. With respect to your answer, what do you think is the max size of the gap for  "the limit for filling with epoxy/woodflour putty."

By the way with respect to your other post, about speaker at Annapolis Maritime Museum:  Until 5 minutes ago it was snowing by me! (1 hour driving west of Annapolis). So far I've been building/epoxying the boat indoors, though in a relatively cold room, so supplemented with space heater overnight.

By any chance are you a volunteer at AMM, I just signed up to volunteer.

Before you go rasping the notch, you might want to try Capt Mike's innovative and effective clamping method.

I try to keep gaps less than 1/8 inch (3mm for the countries that haven't landed men on the moon). Since CLC says 1/4 (3mm) for this boat and it's their design, I defer to them.

And I think that you may be confusing someone else's post with one of mine. I've never heard of the AMM, though now I will look them up.

Hello, the attached clamping method will help to close the gaps between the transom and the planks. 

The clamp will slide a little due to the clamping angle, but if you have the wire ties in place a quick twist is possible.

Good luck,
