Thoughts on PVC stringers

For me the best is the stiffer board you can use that not chatter in bumpy waves. It’s more the quickness of flex return than overall flex max number. To much flex slow boards. Pvc stringer can work good in eps epoxy board because it increase “plastic flex dynamic” =slower return to original shape after flex=less chatter in bumpy waves.

Extruded pvc = pipe = high density, low flex Expanded pvc = foam = low density, high flex I’ve been using expanded pvc as stringer on eps boards for a long time with very good feedbacks. Easy to shape and very good flex. www.facebook.com/surfprofoam

So im guessing some of you have tried electrical conduit or pipe as stringers? I have been thinking of using two 25mm to 32 mm heavy duty, or light duty conduit lengths on each rail.
Drilling the holes down through the length of each rail. Drilling while the board is vertical as the welded drill bit of at least 5 feet in length will bend in horizontal drilling.
I might try it out even though there is less flex with extruded pvc.

that board is CLEAN Mako!

nice job

nice board…

My comments were to the naysayers that do not like PVC foam…It’s a good stringer…and a very good stringer for people cutting their own blanks…easy to work with…

You built a great surfboard. Carry on!!!
