I just did it in my house. It’s a lot more work than just simply putting it in the hole because there’s always going to be something in the way that you’re gonna have to cut and reinforce later on to make sure that you can then secure the door later, but what he was showing was all the process, when you have the opening prepared already
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?
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.
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?
