Thin Aluminum For Templates?

[Tallbald]

I wish to make multiples of several small items like key rings, cell phone cases, and dog collars. I have on hand a sheet of thin, tempered aluminum flat sheet I was given, perhaps 1/16 inch thick. I can cut and trim the aluminum with my band saw and smooth the edges with my sanders to make durable templates. Most postings I read here though seem to choose clear plastic or bag stiffener for templates. Why not aluminum? Am I missing something important? Don

Aluminum may leave marks, like pencil marks, on leather if the edge is accidentally drug along the surface of the leather. Try it and see what you think to see how careful you need to be.

Well, which do you think is easier to cut out and sand sooth so it doesn't mar the leather? And which one can you see through for easier placement? And which one is the least expensive option? How durable do your templates need to be?

Think it through and I am sure you will come up with the right answer....for YOU !

I made templates for my cigar cases out of sheet aluminum. I made sure the edges weren't sharp. I lay it down on the sides of veg tan I get and use a break away utility knife and cut around the template by dragging it along the edge. As long as I hold it down good It works really great for me until I get a clicker die bought.

I've had aluminum react with wet veg tan and leave a mark but I can't think of any other reason as long as you are careful to remove the sharp edges. I had 2 templates made for wallet pockets by a professional and it was cheap and fast. They laser cut an acrylic sheet and you can add holes and slots for reference points.

The only 2 reasons for not using aluminum that I can see is: Possible reaction with the leather\discoloring the leather and the inability to see through the template for psoitioning. Keep your leather dry, "break" any sharp edges and you will be fine.

Other than the potential for discoloration of wet leather (as others have mentioned) I don't see any issue. Just make sure that if a piece gets bent that the measurement are exact before using it again.

I've found out the hard way that once aluminum is bent (even a little bit) it doesn't go back to the same shape/dimensions. My Macbook took a dive out of the back of a van due to an automatic opening hatch. Hasn't sit level ever since.
