The Crossroads of the Aether
Greetings, all. This is my first post on your esteemed site. ( So go easy on me, please. ;-) )
I have need to cut thin brass sheets on a scroll saw. I believe this will work much better if I can "back" the brass with something like Masonite (which I have in abundance). What I'm looking for is an adhesive that will TEMPORARILY bind the two materials. I don't care if I have to do a little sanding to get the glue off the brass, but I don't want to have to scrape at it for hours.
I'm thinking that ordinary wood glue might meet the criteria, but those little brass sheets are 'spensive, and I don't want to waste one finding out. Anyone have experience with this?
Rubber cement can be peeled off, but if you are using thin sheets of brass then the metal might deform when you are removing it.
Another option might be a hot glue gun. The glue should adhere to the brass temporarily, but since the glue will stay on the surface it should be relatively easy to peel off.
the trouble with hot glue is it will leave a void which will cause the metal to deform if you cut it in that area.... plus it will not be a smooth joint between metal and masonite which will mean the saw blade will or might "pluck" at the metal as the blade rises again.
G.L.'s idea is a good one but the removal can be done with a wire saw... lift the edge of the metal up and then slip the wire saw between the materials. then gently saw the joint loose. the saw blade may become full of glue and require you to clean it but this will be the fastest way to separate the two materials with out bending the metal.
Oh a wire saw can be found in a plumbing department... it is used to cut PVC pipe in tight spaces. I am sure it will cut the soft rubber cement a great deal easier than it cuts PVC.
I hope this helps...
Tremendous ideas. Thank you all. I feel like rubber cement may be the way to go here. It just needs to keep the brass from shifting and lifting. I know you can also sandwich the sheet between two boards, and then wrap them all up in tape, but I like to see what I'm cutting.
Well, I tried the wood glue--glued up a small piece of scrap to a masonite board last night, and cut it this morning. It seemed to be going so well, until, as Lady Alice predicted, the brass simply popped off. I guess it's off to the craft store today to buy some rubber cement...
Two sideded tape...and not "tigertape" but the flat stuff that looks like masking tape. That's what we used at Mattel...
And Bestine cleans off most glues...rubber cement thinner.
Ooh! Why didn't I think of that?
Not sure what "tigertape" is, but I'll try to avoid it.
I wonder if double-sided Scotch tape (cellotape, for the non-Americans in the house), would work?
Stopped at Lowes on the way home tonight. Couldn't find double-sided masking tape, but I did find double-sided duct tape. That worked perfectly! It's a little tough to un-stick, but not too bad.
You can use WD 40 to remove the glue but you have to wash off the WD 40 with soapy water...
Wish I had thought of the double sides tape that was a capital idea Major.
Try screwing the brass sheets on the outer edges, perhaps using small washers for added control.
