Hi Paul39,
The photo's look impressive, the glue I use is described by manufacture as polyaliphatic crosslinking PVA hope that helps.

My choice cross-linking polyvinyl acetate for type C & D glue bond ply - Titebond II - same brand on both sides of the Pacific.

It pays to check the glue bond type of the plywood you are using and try to match it for glue performance. Polyurethane may be a better choice for Type A & B bonds.

"Glue BondsThere are four types of glue bond for plywood manufacture described in decreasing order of durability.
Type A – produced from a phenol formaldehyde resin which, sets permanently under controlled heat and pressure. It gives a permanent bond that will not deteriorate in heat or cold or under wet conditions. It is used for marine plywood, structural plywood and exterior plywood which has long term exposure to wet or damp conditions.Type B – produced from melamine fortified urea formaldehyde resin (MUF) which sets under controlled heat and pressure. Type B is suitable for plywood involved in up to two years full exposure to the weather such as in formwork plywood or exterior doorskins.Type C & Type D – produced from urea formaldehyde resin (UF) which sets under controlled heat and pressure. These are interior bonds which are not recommended for any purpose where exterior conditions are involved. Even for interior purposes, C & D should not be recommended for structural applications. For areas around sinks, vanities and laundry tubs, Type A bonded plywood should be used." http://www.awpanels.com.au/plywood/about-plywood/

I do a bit of segmenting and use the type of glue that Rod has referred to. Your equivalent would be Titebond 2. If the plywood is rated for internal use then Titebond 1 would be sufficient, if it is exterior or marine grade then Titebond 2 would be the one to use. In reality, which glue you use will depend on the end use of the bowl, whether it needs a high quality bond or not.

Thanks to all. I'll put up some photos in due course.

Hello Paul 39,
I am not really a segmented turner, so I bow to their advice. However, for gluing plywood pieces for turning bowls , including plywood for pepper mills,
I use Titebond 111 because of its waterproofing ability. It is marketed with green label printing. I also use it for other laminating and find it an excellent product.
Generally, many of us find that the Titebond products are very good. Drillit.




UOTE=Paul39;1868781]I have a bunch of 19mm 13 ply plywood that I would like to glue together to make thick enough blocks to use for bowl blanks.

Like so:

What sort of glue do you segmented turners use? Use the technical name rather than the brand name as I'm on the other side of the pond - USA.

Thanks[/QUOTE]
