yes, a scarf can be used on ply and lumber, if your going to sheath in glass use ''polyester resin NOT epoxy' when u get the required thickness of glass Matt finished with ''Gell Coat'' or good enamel paint, this will allow the polyester to harden.
Epoxy actually needs some thickness to achieve full strength. I have actually considered a layer of mat in the joint. Great jig, love that it rides on the pipe clamp, well thought out, I might add a vacuum port to the back.
I have a question I want to build a 24 ft center console fishing boat using plywood and fiberglassing over the whole boat can I use this joint for all sides and hull.
Wrong...try reading about wooden boat building first. its hard to get the recommended scarf length with a circular saw on the ply edge...and get it straight and feathered. Not to mention you have a min length you can achieve with a regular skill saw .....often will likely have a a sloppy looking line with blow-outs. Taking an hour to scarf plywood is nothing when it comes to hull integrity. This guy is making boats that have a wood finish so he cant hide bad scarfs with fairing compound etc
Best scarfing jig out there so far. Thank you for posting.
Great video. Thanks for taking the time to show others how to do it.
Thanks for the great video. What keeps the jig from moving side to side on the bar clamp?
Would a sacrificial board underneath prevent tear-out? Maybe tape the edges also?
This is great. Simple and effective. You appear to be clamping the jig with the cross-bar in some way. Can you describe how the clamp works? Thanks!
Vacuum port in the back of the jig?
Great video Mike. Thanks for sharing.

Yes, use an 8-1 scarf or bigger, (so 1/2" ply will be 4" long scarf,). I use scarf on ply from 1/4" upward and on timber.

Thanks for this video, just learned a new trick
Best video I could find
Use a number 7 bench plane and a little energy. Way quicker. Done in 5-10 minutes.
Guess I don't understand why you didn't just scarf all the way to the line with router?
And if you click his link apparently it goes to a malware site. That's what the antivirus is saying.

Works Great? NO! Terribly time consuming.... How about a circular saw in a similar jig?
i know right? circular saw takes like 2 seconds lol
