What Glue to Use

[Shovel Man]

Have a glueup that needs more open time. It's a laminated bend that's going to take about 10 minutes to lay up before I bend it, so it can't tack up in that time. It's just wood to wood and not highly stressed. Cool basement shop, KD wood.

Titebond Premium says 'longer open time' on the label but is that going to be enough?

Liquid Hide Glue.

Titebond II Extended has a 15 minute open time.

I've used TBIII for a 10+ minute glue up with no problems (15 layer serpentine cane)

Old Brown Glue will give you plenty of time but the flip side is it needs some time to set up.

I have used hot hide glue for laminations.Have not used the hide glue in a bottle as another post mentions.If using hot hide glue,brush on the glue to each side that needs it. Don't worry about it setting up. Will dry as soon as it cools.
Now you have separate laminations ready to clamp up. Clamp two together and move a heat gun across the work until you see the glue oozing out.Let it cool,usually within 10 minutes or so.Then add second lamination and repeat with the heat gun.Repeat until all the pieces are glued up. If necessary brad nails or screws can be added to remove clamps sooner.

Interesting technique.

You could also consider plastic resin glue.

Unibond 800 is another great option.

IMO, the biggest single factor to consider is what the ambient air temp is where the glue up will take place. The hotter it is the more you need to move to the plastic resin glues or epoxy. At 100°F, Titebond II is tacked up in less than a minute. At that temp DAP Weldwood will give you appx. 15 - 20 minutes. About the same for Uniboond 800. West Systems epoxy (with slow hardener) will give closer to 1/2 hour to 1 hour.

These adhesives do well in higher temps but also have a minimum temp of around 65° - so plan accordingly.

Glueup went well. Used Titebond Ultimate. It gave me enough time, about 10 minutes to assemble then bend all 4 plys at once. It takes a very light tack on contact, just a combination of suction and sliding friction. Nothing a little force couldn't overcome. Phew!
