Stock making

[charub]

Christmas is on its way, I have 2 weeks off work. I think I will manage to retreat away from the chaos that my wife, two almost teenage girls and a 3 week old baby girl will inevitably create to my man cave.
Once inside, I'm going to have another go at a stock. I have made one or two in the past from solid timber.
I came across some rather nice 18mm birch faced ply today at work that looks perfect for the job.

Is everybody still of the opinion that a good quality waterproof PVA is best for gluing the 18mm planks together to form the basis of my blank? I know that there are stronger glues available but I am concerned about glue lines, flexibility etc.

Any advise gladly accepted.

Thanks.

I used polyurethane glue when I made up my blank ? Good luck

Used both Polymite / Cascamite and water activated Gorilla glue and they both work very well. Gorilla glue is more readily available and expands to fill any gaps , so does need clamping up well or it’ll push the joints apart.

Hi

I made the plywood (HW80) stock of these using two pieces of 1" Birch ply (Scrap wood from our patternshop), I glued them together using PVA glue (Also from our patternshop!) and put a load of G clamps on to hold them together, I used a gouge that was intended for turning wood in a lathe to cut the inletting, Got it finished then sold it for some reaon!!

Try to arrange the mated sides 90° to each other for a seamless job

The former wont leave a yellow glue line

I used PVA for this stock for my Scorpion made out of birch ply.

Apologies for thicko response but I don't get this and it sounds crucial.
Dim but willing. Jules

If you have the grain of ply running the same direction (The parts that are glued together) you'll get a 'twice as thick' ply running down the centre, He means make sure the two mating plys to be glued run 90° to each other, Mine both ran in the same direction!!

Thanks John. Crucial then as I suspected. Jules
P.S. Lots of waste for one offs then. J

Just finished cramping together using gorilla glue - jeez, it's messy.

Might be messy but it's the best there is for this job.
Basically the same glue used to make engineered timber frames used in large buildings.

chap near me built a DIY wind turbine a few years back. the blades are carved from a laminate of old school desks stuck together with gorilla glue. seamless build, looks great up close and has been outside for years without a single joint failing.

There have been a couple of comparison tests on the net and the strongest wood glue turned out to be Titebond 3. I dislike Polyurethane glue as it’s very messy but does have its uses, particularly gap filling on poor joints. Another wood glue reckoned to be very good is Cascamite.

When a long time ago I intended to build a wooden support table for my ML7 Cascamite was the glue recommended.

Not sure these days but Cascamite used to be used for laminating bow limbs.
