Thin plywood dado help

[Robert Hayward]

I've been thinking of using 1/8" B/B plywood for miter joint splines. Anyone do that?

If you decide to try it see if you can get 1/8" aircraft grade birch ply in 5 or 6 ply. Not even close to being cheap but the edge grain looks a whole lot prettier than 3 ply BB 1/8".

As long as the arbor hole matches your saw, you can use a variety of smaller diameter blades designed for hand-held saws to get creative with kerf width when grooving.

I've not used plywood, but I have laminated veneer to make splines. Essentially DIY plywood. Nice because you can use contrasting woods to get creative. You can also do something as simple as veneering a piece of solid wood with contrasting veneer to get a striped appearance. All essentially a derivative of making inlay banding.
