What adhesive would be best to fasten Plexiglas (acylic) to
plywood?(Baltic Birch)
I'm thinking epoxy but I'd have to go buy it so...anything else?

I'd recommend polycarbonate (Lexan) over acrylic (Plexiglas). If
struck, acrylic will shatter into sharp bits. Lexan is the
prefered plastic for guards.

I already had the acrylic but I agree with you on the poly.
In the particular application I intend I would "hope" the plastic
doesn't get struck. ;-)

Screws.

What's the application, specifically?

I am making a dust "shroud", "blade enclosure", whatever the appropriate
terminology might be to describe a device to collect dust over a table
saw blade.
I'm making the sides out of Birch ply and the top out of 1/4" acrylic.

NO!!

Don't use acrylic for this application, it's not impact-resistant. Use polycarbonate instead.

And why make the sides out of wood? Why not make the whole thing out of polycarbonate?

Since this project is a "prototype" I will very likely build a Lexan
model. I'm primarily interested in determining how well the device
collects dust from the table top and establishing a method of mounting
the rest of the "system". I will have photos when I try it out.

Keep us abreast of your findings! I have an old Craftsman tablesaw with
a blade-shroud, but no suction. I think it is acrylic, but am not sure.
Finding a really good way to add suction there would be good ...

In that case... make the entire prototype out of wood. Why bother using plastic for *any* of it?

Based on the tinyurl above, there is absolutely nothing to be gained
using 3M-5200.

Avoid acrylic like it was the plague because it will shatter from
almost
any contact by a chip thrown from the saw blade.

Use 1/4" polycarbonate (Lexan) and attach with some #10, pan head,
S/S, coarse thread, self tapping sheet metal screws.

Drill 7/32" clearance holes in the Lexan and 9/64" pilot drill in the
wood.

You need to provide some clearance between Lexan and fastener to
accommodate the difference in thermal expansion.

You can also make use of a 1,500 W heat gun to aid the Lexan
conforming to the shape of the wood.

Shoot a couple of coats of shellac to finish the job.

Have fun.

The working model will be all Lexan.

Thanks for that tip!

I have a good heat gun but I think I'll avoid trying to create any
curved surfaces.

I'd say Acrylic itself. Just like welding two slabs together.

Well, I was planning on using silicone to seal any openings that need

Looks like simple screws through the plexi/acrylic into the wood. If
the plexi/acrylic is shaped properly to match the curvature of the wood
sides, screws should be all that is required. There wouldn't be enough
air leakage to make a difference. Most of the leakage will come through
the bottom which rides on the work piece.

Pan head screws. Flat heads will split acrylic like wedges.

May I try to talk you out of that?

Silicone tends to "poison" the surface of anything that it is used on.
Nothing else will ever stick to it again.
If repairs are ever needed that could cause all manner of problems.


Use 5200 as the adhesive, and as the seal.

Good stuff, Maynard.

Thanks, Richard. I'm getting more votes for the 5200. ;-)
