Trying to put together a simple longbow after 12 years or and forgot a lot of things, especially detail oriented. Slowly but surely I am gaining on it.
That said, I have been seeing some posts from you more experienced types that are splicing those thin, visible veneers together. I have angled my cores and super glued them together, but the veneers look to be handled differently. I have seen a picture where the veneers were looking like one 72" strip. They weren't butt splice I don't think.
Anyone out there ever done this? I have .030 thousands veneers so butt splicing isn't going to work I don't think. I may be wrong. thanks for any direction on this.

Butt splices don't allow for much gluing surface on .030" pieces. I've done it with success, but I've had a few come apart too. Depends on the amount of deflex in that area, if any.
I've spliced them by creating an angled/beveled edge or scarf joint which increases the amount of gluing surface, I then also use a toothing plane blade to groove the gluing surfaces so they can't be starved of glue. I use Smooth On epoxy and cure with a shop light nearby for heat. Those things have raised my success rates.

It didn't work. Search for footed or spliced limbs. Pretty good thread.

Jim: A lot of time those fancy veneers are done in a block form using a good epoxy and then the veneers are cut from the block. I think it would work if you did 1/2"-3/4" thick blocks then re-sawed them into veneers.

What Bob said. The way we learned to do it in Veneer class at school. We had to make a project using multiple spliced veneers.

That's not always an option, in fact, usually it isn't.

I always splice veneers the same way I do lams, fishtail em, and then glue together. Just have to be careful not to glue them to the table, or after spreading epoxy picking them up.

Sorry for not responding to the kind responses. I get a hundred things going and neglect to follow up.
I have spliced veneers together ala married two different kinds of wood together. Matching curved edges, glue then resaw, but that was with 36' pcs and they were easy to handle. Never really gave a thought to ripping 36 inch material, fish tail or scarfing the ends, gluing then resawing them down again. My issue would be sanding something that long to uniform thickness. I just have a drum sanding attachment on a motor for thickness sanding and having to managed and extra 3 feet of material might mess me up. I would need to come up with a support table of some kind.
Great ideas and reminders though. Thanks!

I use 3/4 stock, stack on each other tape or little glue spots so they don't move. Saw with sharp thin bandsaw, don't quit moving even if you get off line. Pop apart, swap one end insert lam to replace kerf epoxy and saw out lamps. I don't touch with sander.If you are careful sawing they fit perfect. Carl
