I'm building a cabinet for my next amp build and am going to use tolex. I'm thinking of using small diameter piping on it where the seams meet. Anyone know if i should use a router to route a recess or a "ditch" of sorts for the piping to lay in or is it typically just glued to the flat surface? Thank ye...dave

Definitely not just glued to the flat surface.

Thanks!

I'm getting ready to start tolexing. I can't find a lot of info on piping. The piping I'll use doesn't have the lip. It's pretty much just small diameter plastic string.Anyone know what gluing approach to take with piping? I was thinking a bead of super glue. Would super glue be adequate? Or something more pliable like silicone or hot glue? Last time I got out the hot glue gun I got hot glue in my hair and ear, fingers were burnt and stuck together and I had to piss really badly. I think super glue would be better.

Not sure where you plan pipinng but here is a good video

Link should work now.
It is a long video, but he completely reworks a marshall head with piping.
Tried to fix the youtube link. No luck... sluckey

Thank you very much! I'll definitely watch that.

P.S. : The piping will go across the top where different colors meet. I'm trying to do something similar to the Marshall Astoria.

On all of my amps, I have routed an 1/8" slot, and run my Tolex over the slot (if you want different colors, only put glue on one side at a time). I use a screen roller to push the Tolex into the 1/8" slot, and use a razor blade to cut the Tolex down the middle of the slot (more or less - a little to one side, if I'm honest). I'll use either some scrap pipping or 1/8" wooden dowel to hold the Tolex in place as the glue dries. When everything is dry, I put my piping in the slot, using the screen roller to push it into the slot, which is a tight fit because with the Tolex the slot is not a full 1/8" thick. I'll use a single upholstery staple at either end of the piping, if it is hidden. On my AC-30, where it isn't hidden, I just made the joint at the bottom of the amp, and was very careful about cutting it precisely to length. No glue should be required for the piping, if the slot is a tight fit, and it would be very difficult to glue it without making it look a mess.

Thanks! I was thinking a slot would need to be routed. I'm at the point where I need to figure which approach to take.

I have a cabinet that I’m working on and intend to use piping on. I used a circular saw blade with a 1/16” kerf on my table saw to cut the grooves for the piping tabs. I could not imagine the round piping, simply glued to the surface of the tolex would hold for more than a week.

BTW, any good sources for piping, other than mojotone and antique electronics? Their selection is really limited.
-
Those are the only 2 I've found.
-
the piping on my randall head is just stapled.ebay search for audio cab piping
-
Mojotone has some different small piping with no stapling flange.
