What my car guy does is puts plastic bead into any material I want to use and runs it through his sewing machine. Like the edge of a old vinyl seat car. He then sews that into 2 pieces of tolex as we measure and cut each part. He is good at it and can cover a 2, 12 cab 2 tone in a=bout 45 minutes or at least less than an hour.
For a joke, I built a bassman for a friend in a 1 12 cabinet with a vintage 30. We diamond tufted, padded and put buttons on every place the diamonds intersect. Not a lot of padding like Kustom does, just about 1/4 inch high. I had a sign engraver make the faceplate out of 3/16 inch white plexiglass. We filled the engraving with bright red acrylic paint and added a thin 1/8 clear cover. Back lit that baby with yellow LED and attached it with brass thumbscrews. White cane grill with a leather red bead. All the stitching was done using dual threading. White and metallic red together. Looks sort of like a baseball.
It turned out so nice, for 2 days I told him I was keeping it as a joke. When he began to get upset I apologized and gave it to him. He said he knew I was not the type of guy who would do that and that is why he was upset. He thought I was mad at him. We laugh about that all the time. I wish I had some photos of it. I will get some next time he comes over with it.
It looks like it should have wheels and side-pipes.
I get most of my faceplates from a company that makes desk signs. They are made of metal. Southern Stamp and Stencil.
www.southernstamp.com. Check it out. They also sell a stencil cutting machine. Check them out when you get time. They sell Marsh inks which will dry on plastic, metal and glass. All you have to do is fill the engraving and wipe off the excess. Using a bondo scraper will remove all the ink except what is in the engraving. Really easy and cheap.
The amps are like out babys, aren't they. I tell people that each one contains some of my soul and lots of my mojo. Might aught to quit doing that because they may not want my mojo.
