Source for Spline weights/Lofting Wales
Hi folks,
Does anyone have a source for spline weights/lofting wales. I am gearing up to build my first dinghy and was looking for supplies. Thanks, Dave G. |

most builders make them. I use coffee cans full of sand w/a nail, and
rip my wales from clear cedar. |

My drafting Ducks and Slines came from K&E.. However I don't remember if they had any large enough for actual lofting. Shouldn't be to difficult to replicate them with some lead, a bent nail and a coffee can. Steve s/v Good Intentions |

Are you going to use them for a lines drawing?

Actually, I was going to loft a set of plans from the table of offsets.

Did you ever find a source for spline weights? You can contact Tom
MacNaughton (do a web search on his yacht design school) and buy some from him. And from Elkhorn Composites, for $27.50 each, you can buy the traditional ducks made from cast-lead: Craig Smith or Dave Hopton Elkorn Composites 25 Grove Street Watsonville, CA 95076 (831)722-1654 Westlawn used to sell white plastic, lead-free hollow, spline weights that you'd buy then fill with BB's. I have these and like them well enough, although I filled mine with lead shot from the local reloaders supply store (gun store). You can read Westlawn at I'm sure the Webb Institute and The Landing School can also point you to sources for spline weights. From what I've seen, the spline weights range from $20 to $30 or so (that's *each*, not for a set) and you'll want a minimum of about 10. I have 15 and have on several occasions needed all of them. For your full-size lofting, note that a hardwood batten (1/4" by 1", as long as your boat plus about 8 feet) works will. You can lay out plywood, put nailers across the seams to hold them together, then draw in your baseline and centerline, square off the stations etc. Put a fine finishing nail through each offset point and instead of using weights, use spring-loaded clamps to do the fairing with the batten. You sometimes have to mark a fair curve, remove the batten and nails, then relocate some nails and re-bend a fair curve with your batten a couple of times to achieve the fairest curve that produces the best average through the original offsets (discounting the outliers that are obvious typos that is.) Here's a picture of me doing just that: http://www.advantagecomposites.com/tongass/step8.html Good luck, Brian -- My boat project: http://www.advantagecomposites.com/tongass "David & Margaret George" wrote in message ...

I'm lofting a 38' Diesel Duck today with a spline weights that I made by
melting down tire weight lead. Couldn't find a lofting floor that would allow me to drive nails so I had to have another way to hold the splines. I'll let you know how it works and, if it works well I'll give you the details on how I made my spline weights and battens. -Steve On Fri, 17 Oct 2003 21:16:41 -0700, David & Margaret George wrote (in message ): Actually, I was going to loft a set of plans from the table of offsets.

Okay, we completed our lofting and it was a success, so here's what we did:
I melted down tire weights (got 2 buckets worth, must've been at least 300 lbs., for $40) and used old bread loaf pans as forms. I tried the little tiny loaf pans but the resultant 8-1/2 lb. weights weren't really up to the job. The ones that I made in full size loaf pans were 15-20 lbs each and worked great. I glued the finished lead ingot on to a piece of 1/4" plywood that was pointed at one end. Used Gorilla Glue. I got the idea for this from the (I think it was) July issue of Duckworks Magazine (www.duckworksmagazine.com). My battens (or wales) were simply 1x2 s ripped in half so that I had 2 pieces that were 1-1/2" by 5/16". Since these were only 8' long, I butted them together and used the same material to make a butt block about 2-1/2' long. Granted, this wasn't the best type of batten to use since it didn't bend absolutely fair at the butt, but it wasn't bad and it was what I had on hand at the time. A one-piece batten would be highly preferable. During the losfting, I set the spline weights so the point of the plywood base was at the points I wanted to use. The weight of the lead spline weight was enough so that it didn't slide and would actually hold the batten where it was supposed to. On the most extreme curve at the point where the stem meets the keel, my wife had to hold the weight to make sure it didn't move due to the pressure, but if she hadn't been there I would have just piled another weight on top and it would've held fine. I used 8 weights and, although it wasn't enough for a continuous run, it was plenty for my 16' batten. Good luck to you. -Steve from Silverton, OR On Sat, 18 Oct 2003 8:24:55 -0700, Stephen Yoder wrote (in message nk.net): I'm lofting a 38' Diesel Duck today with a spline weights that I made by melting down tire weight lead.

Hey "Steve from Silverton, OR", you're in my old neighborhood. I grew up
outside of Salem, north end, near Hazelgreen. There was a woman at our church (Christian Center) in Salem by the last name of Yoder ...this was in the 70's. Any relation? What kind of boat did you say you are building? Brian (now in North Albany) "Stephen Yoder" wrote in message thlink.net...
