My new project

[seth30]

alright got all the plates made, and I was going to rivet them on but realized something   I dont have sealant for the metal plates.  What do you recommend to go between the plates and the boat as a all around sealant?

3m 4200 if ya need to remove it later. if not 3m5200.

Thanks!  Is that something I can find at ace or home depot? 

[seth30]

any ideas on seats?  the ones that I pulled out were about as steady as  sheet of paper   Or do you know of a quick and cheap way to make some?

[seth30]

Or is there anybody on here that is trashing there old jon boat seats in place of new ones?

You could rivet some brackets on the sides of the boat and use a piece of 1X12 mahogany.  Glue your brackets with your 3M adhesive as well.  I made new seats for my little Starcraft, then had stainless boxes made to hold foam under the seats for flotation.

Can you provide a pic?  This is my first boat and I have a lot to learn.

Seth, PM me your email and I will send you a drawing if I can.  I am not at home to take a pic for a couple days.  Basically, I would have a three-sided box the length of your seat made with flanges that bend out with screw holes and on the ends have a flap bent in on each side to keep your piece of foam from sliding out the ends.

Tried to email, won't send from my location for some reason.  Here is what I tried to send.

Seth,

I can’t remember how wide the seats are on my little boat.  They are at least 1X12’s which are 11 ¼” wide.  This would be the minimum width I would go, maybe a little wider if someone has the wood available.  The drawing would be for an 8” X 8” X the length of your seat.  The screw flanges that fold out at the top would be ¾ “ wide, the flanges on the ends that fold in would be at least ¾” but wider would not hurt.  For my boat I had completely enclosed boxes made, the problem with that was that it is not sealed at the seat joint and the enclosed box does not drain if swamped unless you turn the boat over.

The two views are a 3-D one where the red lines are the folds that would be out of view if this were solid metal.  I am not trying to talk down to you but am not sure at what your drafting experience is.  The second drawing is a not to scale one of the flat cutout sheet of metal where the blue lines are the bending lines.

Simpson Co makes some galvanized stair brackets that you can pick up at Home depot.  You could bolt or rivet/glue these to the sides and then mount the seat to them.  You can probably figure this out as you are probably not a complete newbie to construction type stuff if you decided to take on this project.  I would put an extra coat of paint and primer on the hull side of these brackets as well.

Good luck with your project.  If you have any other questions, feel free to drop me a note.

Sorry the email didnt work out, after all its a hotmail account   So the gavalizned goes over the wood?  We have a pretty good home depot on the island here.  I will check it out tomorrow   Thanks for all the help!

This box would hang below the wood seat.  The long 3/4" wide sections would have holes tapped in to screw up into the seat.  The other dimensions on this example are 9 1/2" wide and 8" tall on the two sides.  The total width from outside of flange to outside of flange would be 11"

Here's some more info on the pic.

Thanks for the new diagram   That makes a lot of sense now!  Without the seats in my boat the thing is really flimsy, and this will help sturdy it up a lot!

It will definitely help keep the gunnels parallel.
