Trout boat under construction

Building this on a budget, not because I have to but I find a perverse pleasure in doing so.  It's the farm upbringing I guess.  Now, before someone says I could have bought a manufactured river bot for $1,500 and it was already done I know I could and have seen some on Craiglist, but what's the fun in that?  I love building things.  This is also my learning project for a more ambitious one to learn  the epoxy and fiberglass side as well as picking up some more woodworking tools.  I hesitate to post this but the next project is a mahogany Barrelback 19 runabout.

Get this figured out, I will learn to weld plastic, think a trout boat out of polymer hull, VHmw-PE would be great with a jet????? Similar to the Boulder Boat Works:

Only in a trout boat. We need you down here....

When I built my last jon boat, I went through a lumber yards entire stock on two different occasions to find the five clear pine boards i needed for the bottom and sides,

They did have some pin knots, but were basically clear, so it could be done (10 -15  years ago).

Not a lot of visual progress.  Got the transoms done with two coats of epoxy.  Going to start reassembly tonight.

Built a scarfing jig for my router to cut 8:1 scarf joints for the gunwales and chine logs.  They need to be one continuous piece.  At that ratio an epoxied joint will be as strong as the base material.  Worked pretty well, ready to glue with no sanding or planing.  Not a very good picture but there are two tubes set 16" apart and one 2" higher than the other.  The router is mounted to a "sled" so that it cuts the scarf.

I have no wood working ability and I find this fascinating.  Very cool!!

Yeah, great project, keep the updates coming.

Not a lot of visual progress but definitely some hours.  Reassembled all the frames with a coat of neat epoxy on both surfaces with a layer of thickened epoxy between them.  Thickened is made by mixing filler like wood flour (sanded wood dust that is really fine).  By brushing on a coat of neat or unthickened epoxy first it keeps the wood from sucking up too much of the epoxy from the thickened one, drying out the joint and making it weak.

I got the gunwales and bottom chine logs routered and beveled and glued up the scarf joints.  Installed them today with the same method above.

Tomorrow I'll flip the boat and install the bottom chine logs and start glassing up the bottom floor sheets into one 20' long sheet.  You can scarf the plywood together but it's easier to wet the joint, install a 3" wide strip of fiberglass cloth and then wet a 6" wide strip right over it and weight it down to clamp it.  Then it is time to install the floor.

1) Scarf joints

2) Stein has ALMOST as many fancy C clamps as Dave has Zinkers/Zeros

3) look forward to you being around more

2a) Not enough, I was scrounging in the bottom of the drawer for anything that had a threaded screw in it.  I really need a couple dozen more.  Matter of fact, I think I'll stop at lunch for some.  I was actually a bit light when I got to the other side.

3a) Makes two of us.  Four more years...

Here's a neat thread from the past.
