Step 2: Framing the box

We are gonna skip the seats since I was using a crummy camera for the seat construction.  The seats are identical to the top of the motor box so consider it the same only smaller.

So the box was built out of 1/2" plywood in two pieces, a three sided lower portion joined to the floor and transom and the top with is three sides with a top that will flip forward to access the engine. The entire box is covered with vinyl with a cushion on the top. The top portion of the box was probably ok to reuse the wood but I replaced it anyway.  The lower portion of the box being on the floor of the boat got wet much more often and was rotten in the corners and other areas. So... using the old box for measurements I started my plan.  I had Home Depot cut the plywood into strips along the length of the panel to make it easier to move and reduce my cutting needs since I did not have an eight foot saw guide.  So I really only had to cut these pieces to length.

To assemble the box I frames some strips of pressure treated lumber about 1"X1.5" I had lying around and used 1" staples and tightbond II waterproof wood glue to hold it together tight.

Once assembled I did a rough sanding to remove splinters and break the edges for the vinyl.  Once sanded I put two coats of Sherman Williams exterior latex paint over everything.

Once the glue was set these boxes are very sturdy and once they are joined to the boat this thing is going nowhere!
<p>Please tell me how thick (the weight in oz per) your vinyl is. Also, does it matter what weight it is? When do you use a 28oz and when to use a 35oz? Thanks.</p>
The weight of vinyl is not as important as where and how the vinyls are produced !<br>Most Asian and South America Vinyl Mfg Source Raw Materials (IE Resins and Plasticizer)<br>From China these raw materials are inconsistent and not reliable.<br>Your boat seats will mildew and First Turning Pink then Brown or Black !<br>If you buy Presewn Trim like Welt or Hidem ASK FOR Marine Certified TESTED GOODS !<br> If your supplier doesn't OFFER ASTM TESTED GOODS FIND A NEW SUPPLIER ! ! !<br>THE Warning language used by import suppliers !<br>Passes U/V <br>Or <br>Mildew Resistance <br>Those statements should be followed by Test Methods and How Many Hours Goods Pass Test For !<br>Most Original Equipment Manufacturers require 1000 hours min. UV Test !<br>Asks Your Marine Vinyl Suppliers for testing method use by their fabric manufacturer !<br>ASTM TEST METHODS ARE WHAT MAJOR AUTOMOTIVE AND BOAT BUILDIERS REQUIRE.<br><br>IT'S AMAZING HOW MANY PAPER COMPANY'S IMPORT SO CALLED MARINE VINYLS WITHOUT TESTING EVERY BATCH....<br><br>
What Brand of Marine Vinyl did you use ?<br>Please send current photos !<br>
Sweet!! Thank you for the idea of notching the piping! it gives me an idea for remaking my motorcycle saddle. <br />What did you use to form the piping? <br /> <br />Cheers!
that was a smart idea to replace the top...saves you from having to tear it all apart later or building a new one later.
Yeah, once I was in there and considering the woodworking part is the easy part I bit the bullet and decided to do it right. Thanks for the encouragement, expect to find more as time allows. Don't forget to vote for me in the challenge.
Great stuff! Keep it up. <br><br>Put a link to you on my boat building blog. Hope to see you continue the detailed info.<br><br>http://www.craftacraft.com/vinyl_seats<br><br>Bruce

looks great!! <br>One heck of a lot of work too I bet....but well worth it! looks as good as a factory job!<br><br>TY for sharing Sir.
wow i might do free yahught fix it with this
Absolutely,<br><br>If you pay someone to do this for you that free boat becomes expensive very fast.
