SCAMPers:
Moving forward with the build of #330. Now, one thing that has me worried is skegs! I have no idea what to do. I have a pattern that I got at SCAMP Camp, so I have at least the outline. I don't have a band saw, and am not really a woodworker, that is for sure. What would be the easiest way for me to make some skegs? I could probably cut 3/4 inch plywood with a jig saw, and glue together, and shape it. Would that be adequate? I am worried about trying to work with hard woods. I am not sure how I would do it. Furthermore, what will be the best way to attach. Should I screw through the hull into the skegs once they are built? Thoughts for simplicity here?

Hi
You can cut out and laminate plywood to make skegs. The method is quite simple.
Cut out the pieces from the pattern I supplied you but make the cut out just a tiny bit larger (like the thickness of a sharpie pen, good for drawing the pattern) so when you go to shape with a sander you have a little wiggle room. Wet out the pieces, glue up as you would any other element of the boat on a thick flat bench with clamps, weights even some screws to temporarily hold them together or on a flat floor with adequate weight. Make sure the pieces align as you apply clamping pressure.
*Clean up squeeze out to leave as smooth and clean a working/shaping surface as possible. Come back to the laminate after about a half hour to clean up any additional squeeze out, it happens.
After the cure you can the then take the skeg laminates to a bench vice, clamp one in or both side by side for shaping consistency and shape with a sander. Careful rough shaping with belt sander if needed (go easy here a belt sanders can take too much off very quickly) is a possible start then you can refine with a palm sander, etc.
During the shaping take the skegs to the upside down hull and check their fit, shape as needed.
Also round over the lower edges with a trim router. Fiberglass the skegs with 6 oz cloth and finish as you would the hull with fill coat, graphite (if you are using graphite) etc.
If you want finger grooves let me know and I can walk you through this procedure. This will require a plunge router.
I suggest gluing the skegs to the hull and screwing them from the inside of the upside down hull with about 6 SS screws each to pull them down snugly.
I have noted your email to me on the other construction question.Look for my reply email. How about a phone call? It would be great to catch up in any case.
Hope this helps!
Best,

Re: Bamboozled by Skegs!
I was advised to make mine from hardwood elsewhere on the forum. I started with plywood, but decided to use some rough red oak I found at crosscut lumber in seattle.
I drove through a few stainless screws from inside the hull as the glue was hardening. Make sure you measure correctly where to drive the screws and drill a pilot first.
Also make sure that the skegs will fit on your trailer. I extended the fat part of mine by just a few inches aft so that the skegs would for sure fit the rollers on the trailer.
I then epoxied the heck out of them to cover the rough cut and a nice big fillet.

Re: Bamboozled by Skegs!
So I thought I would follow up.
I glued the paper pattern I had for the skegs onto some 1/2 inch plywood and cut it out. I then cut out 4 pieces of 3/4 inch marine plywood from the 1/2 inch jig. Now, I tried with a trim router, and that was a mistake. With no table router I just cut them out with the jig saw. They were a bit uneven, but still pretty good. I laminated them on a very flat surface, and then shaped them with a portable belt sander, orbital sander, and hand sanding. Rounded over the edges with a 1/4 inch round over bit. They came out great. I then glassed with 6 oz and fill, sanded, and I had me 2 very nice skegs. I glued the first one to the boat today using 5 screws through the hull from the cockpit side, and that worked out great. I will attach the other this weekend, and then fillet. So, I am happy with this. I will then put on UHD plastic 1/4 inch stuff to them for dragging it over the sand etc. All is good.

Re: Bamboozled by Skegs!
Yay, good job, they'll be rock solid, I'm sure! I bought a piece of Douglas fir for mine. It was the most expensive bit of wood in the boat! Used a jig saw to cut the shape, hand tools to finalize (ie: fix all the errors made by the jig saw), and a borrowed router to round over the edges. It was a very joyful job!!

Re: Bamboozled by Skegs!
Figure I would show you how they look nearly completed. These are the 3/4 inch marine plywood cut and laminated, epoxied, shaped, rounded over, then glassed. Then attached to the boat, big fillets, and finally, the hull paint. I am now attaching UHMW plastic glides to the bottom of the skegs as seen here. These are the pre drills to get them to hold shape. I will then remove the screws, drill out to 1/4 inch, fill with thickened epoxy, re-drill, run some 3M 4200 along the line, and then attach the rails again with the stainless screws. I think this will work really well. Should be durable, slide on the trailer, and take a beating on the shore.

Daniel,
Very nice work from someone who was initially bamboozled! Nice job.

Thanks! This is a great community, and I got lots of ideas here. They came out well. Should do the job!Brent65 wrote:Daniel,
