Curved Rail Lamination Process - Great Lakes Woodworking 

Excellent

I spray a light coat of lacquer or paste wax to the rail before glueing. The bending mold and excess glue come off with very little effort and save HOURS of sanding.

Curious as to why you used a pva rather than a plastic resin glue.

I was thinking "look at all that squeezouoooooohhhh, shrink wrap!" Brilliant.

Question what if its also bending downwards will the same strips work for not only bemding the same axis as in your video but also if its bending downward?

Strip-laminating handrail, is lot more work than just milling handrail segments from solid wood, especially if you process any CNC equipment. The fact that you end-up with longer lengths however, is a definite advantage. Still, there are serious disadvantages as well... Spring-back, de-lamination, stripped glue-lines, extensive form construction, mountains of clamps (which get stolen when left on job-sites overnight) hours of dry-glue scraping and sanding,, handrail profile limitations (based on available, bender-rail styles.) Can you tell, I'm not a fan? It is something that amateurs can sometimes pull off, although I wouldn't recommend it. BTW, you can also get launched of the 2nd floor with all your nail bags, while tugging on a wet bundle (I hit the concrete before my hammer, which then hit me over the head.) Did I mention that you really need two guys to bend rail?

Get rid of the stupid slow-motion.
