Vince -> Binding and Purfling (Jun. 15 2015 9:07:14)

Which approach you have when creating the bindings and Purflings.
For the Bindings I glue the veneers on a Plank with approximately 3-4 cm wide and saw and plane the package to the desired height after drying . Then I saw the individual bindings. The same I'm doing more or less with the Purflings. Both bent in a Fox Bender. I use PU glue or Titebond. What are you doing?

I do the same as you Vince. Although I use a wider plank as I am generally working on 3 guitars at a time. I only use PU glue Titebond brand at the moment. I find that the TB original rinkles the purflings or just gives up under the heat.

I glue largish sheets of veneer together to make the seperate purflings of say 150mm wide or as wide as the narrowest veneer in the pattern.

Stephen,
Titebond III is much more resistant to heat than regular Titebond.

Cheers John, I shall have a look at that.

The other advantages for using PU I can think off that PU has is that it doesn't curl your veneers while you are gluing and also no matter how many veneers you glue the set time is alway 1 hour. With the water based glues you will have to wait 24 hours with many layers of thin veneer.

You're right the water based glues can be a nuisance due to curling. I'll give the polyurethane glue a try. Thanks for the tip.

I do about the same except I bend using a heated bending iron. I tape two binding strips with side purflings together, with the side purflings in the center, using 3 or 4 pieces of tape. Then I hold this under hot tap water for half a minute or so, and then bend, starting at the waist and moving the pieces of tape to already bent areas as I go. For purflings only, such as BW or BWBW, I don't wet them. I use Titebond glue.



alcazaba -> RE: Binding and Purfling (Jun. 16 2015 3:47:01)

where do you buy from the planks? here in US I haven't been able to find them.

Hot hide glue for bindings does not come loose with heat. Though is a bit of pain to work with on purflings.



Stephen Eden -> RE: Binding and Purfling (Jun. 16 2015 9:11:29)

I use a normal bending iron to. I made a bending jig using 3x 150w light bulbs which worked ok but I still had to do more bending after. I should go for the blanket and jig route as it could give me a little speed boost but its just getting round to it.

I use the tape method as well although I don't move it just bend the taped areas too and usually bend 12 to 16 at a time.

I buy large lumps of Indian Rosewood 'Decking' and cut the planks off of that.
