Riviera stringers

Post by Idigplanes »

Hi all. I am having a hard time finding quarter sawn Doug fir or white oak for my riviera stringers. What other options might I be able to use and/or get my hands on here in southwest indiana?

Quarter sawn is the gold standard. How about laminating two layers of plain sawn layed up with opposing grain pattern to get the stability without the sourcing trouble?

It shouldn't be hard to get white oak in Indiana. There is a ton of it here. I know of at least two good sources up my way.

I’ve checked around and haven’t found any. I was not aware that laminating flat sawn would achieve the same affect as quartersawn. Maley and wertz didn’t have any.

laminating two thicknesses should make for a stronger timber than one solid piece.

Ok so I’ve got enough q sawn white oak to make my stringers with. I will have to scarf to achieve the length and laminate (2 lams) for thickness. Is there a special process to follow? Glue and clamp? Mechanical fasteners? Special epoxy? Being such an integral component of my build, I’m a bit nervous. Thanks guys.

If you are laminating two pieces to make full thickness, I would stagger the the joints a couple of feet, Poxy Grip them and call it good. You could even lay out the joints in the motor stringers to land on a frame instead free floating between two frames. Use mechanical fasteners if you want to as long as they don’t interfere with engine mounts.

White oak tends to burnish in the saw/planer. Sand the surfaces to be joined with 80 grit and wipe with alcohol. There will be a pair of fasteners every 24" at frame to stringer connections. Tom

For sure rough up gluing surfaces on white oak. I used 4/4 white oak sandwiched between 3/8" Okoume. Oak was roughed up and epoxied with SB screws to locate pieces and ring shank nails every 12". My stringers have been rock solid for over 6 years.
