Topic: Temporarily joining wood sheets

G'day
I've just got access to a bandsaw. Much better a cutting curves than I thought. I'd initially like to cut 2 identical parts for a toy that has quite a few curves. So I'd like to temporarily join two pieces of ply to cut at the same time. There are some suggestions out there, however using double sided tape (too thick for my liking) and blue tack don't appeal. Using short screws was one option though that would leave holes that would need to be filled.
Any ideas ?
Regards
Alban

Hi Alban,
You can do this by gluing two or three bits of paper - or better still - thin card, on both sides and sticking the bits between the two pieces of ply you want to hold temporarily together. Stick the bits between the ply near the edge of the cut line. You can lever them apart with a chisel or knife after you have made the cut and sand off the remains to a clean surface. Good luck - Warne

try making a loop from masking tape...sticky side out...press the sheets together. May have just enough grip to hold them while you cut. The gum can leave a stain tho...and needs to be sanded off before painting.
Cheers.

Thank's for the suggestions. Masking tape loops were mentionted to me,though I had dismissed it, as tape loops I tried before for other things have always seemed to me to have some movement. I have to say I was quite supprised when initially playing with the saw, how controlled and well gentle not's quite the right word it was.
At least in the beginning I (at the moment) intend using slightly larger pieces of ply, that will be glued together well outside the cut line. More waste, but all on a learning curve. As the saw has a 14" throat in the old lingo, it'll all be within bounds.
The real fun will begin when I have to replace a blade or what ever. Getting the settings right......

Hi Alban,
With a 14" throat, I guessing its a bigger saw - just be careful with curves - if you need to make tight curves just take a bite at a time and gradually get to your line and you will save your blade. Don't try and adjust while the machine is still going turn it on and off as many times as it takes.
As for holding the ply together - obviously depends how thick the ply is - why not try just nailing it together with tiny panel pins? If you put sharp side up you could cut around them?

Try a few panel pins (tiny nails) or maybe staples.
Alternatively double sided tape. Whatever turns you on.

Hi ALBAN
Construction adhesive, liquid nails, fuller bond,sika there are a few on the market; really does stick like thick viscous brown stuff to a blanket; you'll see.
A total of 2 or 3 small spots, thumbnail in diameter, as close to the outside of the shape as possible, equally spaced around the shape.
Let it set it won't come apart until you gently cut it with a stanley knife or other thin blade (hacksaw).
Glue it, position it, sit a couple of bricks on it for 24 hours and you're the master.
In a dry atmosphere is best; lounge or bedroom is good and a great conversation starter with the better half.
Only hastle is the time taken for glue to set, but it won't let go; wonderful cheap stuff.
All the best in your adventure.

Good evening ALBAN,
I've had some success using a few blobs from a hot glue gun. Three or four small blobs evenly spaced around the edge. ( Inside where you want to cut, The voice fo a bad experience! ) Sets in no time, and use a chisel to pry pieces apart after cutting and sanding. I used the chisel to peel off the glue blobs left on the surfaces.
Works for me.
Good luck!

Thanks for all the tips. I think I might go with the blue tack first. Easier to get apart I suspect. We will see..
Regards

If I might ask, Why dont you like to use double sided tape?
I do lots of wood work and I use a really thin double sided tape.
Holds until I make it let go and very little residue left to sand off.

I'm with this one, I've been a woodturner, and have been able to turn a piece that was connected to stock simply by have a piece of manila folder with PVA glue on both sides between the pieces. When the turning is finished you can separate the paper and sand up.
Another posssibility would be a few dobs of hot melt glue at a couple of spots,
which can later be separated and cleaned up
