Pattern Transfer Technique

[sbmurphey]

Had an early start this morning with the time change. I started surfing the web looking for some additional ways to transfer the drawings onto my sheet metal.

I found the following method used by jewelry fabricators worked for me.

Print drawing on a laser printer. (Confirm scale and quality of scan prior to trusting this method.)
Place print face down on metal. (You will project a mirror image. If this is not acceptable, consider mirroring the image before printing.)
Use a solvent to release the toner. (I am currently using acetone. Xylene was recommended by the jeweler I got the idea from. I'll have to find some and try it.)
Press the wet print into the metal.
Peel the paper away from the metal as the solvent flashes off.

I'll have to give this a shot, thanks Stephen.

We glued printed paper patterns to the metals with 3M Super 77 spray glue. Used a Lee Valley optical center punch to locate the drill holes. It is easy to cut shapes to size on the metal bandsaw. We had a cheap 1/2" x 65" band saw for cutting part & then part was sanded to the lines using a 1" x 30 belt/disc sander or bench grinder. The paper & glue comes off easy with mineral spirits or alcohol. Acetone & especially Xylene should be used after reading the MSDS with caution.

I do something very similar to Glenn but use rubber cement from Staples. Rubs off with my thumb and I clean with naphtha.

That's what I do and has worked great for all my parts.

I like the rubber cement idea as it does come off easy with no obnoxious clean up. Good pointer.
