Yes, can do lapstrake. I built the Herreshoff Columbia dinghy which is the lapstrake version of the catspaw (and a foot shorter). Herreshoff planking is 1/4".

Underlayment from the big box store works well. More than 1/8 but less than 1/4. All that really matters if you have something that you don't edge set.

Personally, I found the hot glue ladder...

Louis did adjust a small bandsaw to do a rolling bevel, but you can only cut timber up to a certain size/weight on it because the table tilts instead of the saw, and so heavy timber is going to want...

I made a similar setup with a keg, but wound up grinding the entire valve off so there was just a gaping hole in the top of the keg. Then I snagged a flange from a big box store that would cover the...

I'm a total amateur and I have no idea how to assess that boat based on the pictures above. But, I'm going to address something that is, I think, more important.

OP — why are you interested in the...

1. I just dropped 5mm doorskin ply on my garage floor, butted the edges together and dropped some weights on them to make sure they didn't slide around. If you don't want to crawl on the floor,...

Thank you!

Miscellaneous was stuff like bedding compound, my steam bending setup, oar leathers, extra clamps, jig materials, a few small tools I didn't already have, a handful of books as...

Oh, and because I know someone will ask, pictures below:

When I started my first build more than two years ago, I found it hard to find good information about what to expect during my build, especially costs and timelines. I promised myself that I would...

Can't imagine any issues as long as you listen to what Nick said above then.

Are you bending parts of the backbone or are they all sawn?

Thanks for getting us to a page 4 Chris! No idea what went wrong with page 3.

I'll keep the updates coming tonight. I don't know exactly where I left off, so I'll do some backfilling with pictures.

I can't seem to get it to come up either, so I'm not sure I can continue this thread. Anyone ever see this happen before?

One interesting bit to note about the stern seats — because the seat risers wound up with a small bit of curve to it as I...

One other note on the riser - boy was it hard to make sure it was fair without being able to get in and sight down it very well. But I think it came out okay. You can see it a bit in these next...

In the realm of things I forgot to photograph — seat risers and floors.

Floors were cake. I used a contour gauge to capture the shape of the keel and planks at every frame, then copied that onto...

It's been a while since I've posted — been busy working on the boat in all my pandemic-inspired spare time. I've been pretty bad about taking pictures and things might be out of order, but I'm going...

Beautiful job planking up. That was impressively fast!

^This. It's not just about you.

And the nearly final product -

Just need to fix that grain tearout and round some edges over to make it look prettier and I'll probably call it good.

Got 'em fit and reporting back with results here -

I stuck 120 grit onto the wales and worked the block back and forth to see where it hit, then used a card scraper to take those areas off. When...

This took me way longer than just cutting out some knees on the diagonal would have, but I am very happy with the result.

The final knees glued, shaped, varnished, and fit into place.

sp_clark - it's the Herreshoff dinghy. I can get pics next weekend when I travel back to the shop.

Yes Gib, going to bed it in dolfinite.

Sounds like the lipstick, carbon paper, and chalk are...

I'm struggling to cut my oarlock pads to sit on the inwale and guard without any wobble or visible gaps. I think fitting my breasthook and stern knees was way easier.

My handiwork with a block...

Yes, the broadstrakes are a bit wider. This helps keep the planks around the turn of the bilge reasonably skinny so that you don't have to back out too much material. Barry Thomas' book Building the...

Thanks for the input everyone! I do love the idea of a brass shim, highlighting a first timer's lesson in fitting wood to inner curves. But for simplicity I think I'll split the difference to make it...

My inwale is about a thin saw kerf too short, probably 1/32"....you can guess how that happened.

Building context:
- This is an 11' 6" Herreshoff dinghy.
- Guard, stern knee, and...

Varnish it is! Thanks guys!

About to install an inwale in my Herreshoff dinghy, and trying to decide how I should finish it.

Gunwale Construction - #10 copper rivets through through the guard, plank, frame, and inwale.

Gib thats beautiful! Do you have a picture of the whole deck after rubbing out?

Since you want to expand your list of options, you could look into Deks Olje D1/D2. The D1 is a penetrating oil that soaks deep into the wood. A lot of people often stop there when oiling a dinghy...

AFAIK oak doesn't turn black from water alone. But, if there are iron fastenings in it and it gets wet then it will turn black with iron sickness. And if it's treated with any kind of linseed oil...

For the carriage bolt that runs through the skeg, keel, and knee, the first thing I did was poison the holes with cuprinol. Then I just drove the bolt in and wound a short strand of cotton caulking...

Gib - those two blocks clamped to your planer bed, are they for consistent depth adjustment? Or something else?

I'm assuming you're doing traditional construction since you mention WRC. If so, you'll be fine. Much larger transoms are made with real wood all the time. Use good quartersawn stock to minimize...

Heh, I had a feeling that was the case Gib. Didn't want to lead anyone in my response.

I'm not sure how comfortable I'd feel vaporizing ammonia in my shop...

I was going to send you a link to a thread response about Kirby's that I have bookmarked, and then I realized you asked the original question there...

This video popped up on my YouTube recommendations today and I thought it might be of interest to some here https://www.youtube.com/watch?v=1pPKUgpn0CI

This was particularly interesting to me...

No cats or swallows. Nothing drips from above and I wasn't in the loft space above to disturb any dust. No greasy fingers because it's just me in there and I was wearing nitrile gloves for all but...

Thanks David, good to know. Interesting points about MS and tack rags. I don't think it's MS for the reasons you say, but I did tack from transom to stem so maybe the rag was loaded by then and a...

Edited, tried a different upload method. Can you see them now

P.S. Here's the paint job as a whole in case anyone is wondering what the big picture looks like. She needs more coats and it's definitely not perfect, but other than the two blemishes I'm pretty...

First time painter here and trying to debug why these two spots happened:

Some context:
- The substrate (more on that later) was sanded to 120 grit, vacuumed, wiped with mineral...

I'd agree on skipping station 8. I used it and it was unnecessary.

If you overbend your batten on the lofting floor between stations 7 and 8 to create a fair curve, then your transom bevels might...

Uwe - I'm finishing up my Columbia model dinghy, which is what the Catspaw was derived from. It's my first build as well. I'd echo nearly everything Eric said in post #10.

- Goop, not glue, in...

P.S. timo - saw your building thread and the paint job looks great!

Sorry, I meant sand between coats of the 1959 itself?

Also, did you guys sand between coats? The tech sheet doesn't seem to indicate - it just specifies overcoat times. It does specify sanding between priming and coating, but not between coats, which...
