Ive searched a lot over this forum which helped some but i need detailed infromation on installing a my own stringer on a foam blank for my first board which ive chosen to not be stringerless ?
Use a piece of masonite to use as a flexible straight edge. Make sure it’s wide enough so you don’t get any side flex, something like 12 in wide. Clamp that to the bottom of the board. Now take your router, with a speed controler to slow down the rpms to 8,000 or so. Use a high Hilux bit, mill end, or a Eager Beaver muilt directional bit from the HD. Cut the blank in half with the router, (optional, run both ends of blank through surface planer) Get your stringer material, put the fresh cut blank on end and draw your rocker on the stringer material. Take a jig saw and cut rocker profile. take all 3 pcs. Stringer, side A, side B of blank, and glue up with lamination resin with a little white pigment mixed in. Clamp together with at least 6 - Pony 3/4 in bar clamps, don’t buy the 1/2 in ones…they flex and distort.
If you don’t have access to any of these tools: draw line down blank, cut with hand saw, sand both faces flat with 1x6x24 sanding block, glue in stringer as in above, and clamp. Don’t try to substitute tape over clamps, you need clamps.
Just think about all the fun stringers you can put into your surfboard with this amazing masonite jig!! Why you could do a figure eight, just cut one side in a S patern, glue it up, let dry, flip the jig over and cut the other side, wow! amazing!! amaze your friends!!

Thank You That Helped Immensely
Aquatic,
Before you glue that thing up, remember to support the blank, especially where the clamps are. Check out what happened to a blank I glued up, and I didn’t support it properly… The clamps can weigh quite a bit.
There was quite a bit of unwanted ‘concave’ glued into the board, that I sanded down, making the blank thinner than planned.
