I haven't covered a cab yet but I have worked with different contact cements quite a bit.Andy Le Blanc wrote:The best thing I've stumbled upon so far is a spray application of adhesive
on the fabric backing. Thick on the cab, but controlled on the tolex.
With metal or plastic corners the time to cover is in minutes.
Cutting in corners simply takes practice, but a controlled spray is essential.
You wont melt the tolex as the driers flash off, or risk over application that
happens with a roller or a brush, and the time to apply is greatly reduced.
The adhesive you use for tolexing seems to be the most critical item on the list.
I have read that the good old 3M 77 adhesive doesn't work all that great.
Which is strange because that is the stuff I have the most experience with.
Maybe it was another similar product.
The glue should be able to handle warm temperatures such as gigging or being stuck into a hot trunk of a car.
I used another product made by Performance Products Aerosol for installing a headliner in a car.
It seemed to bond very well and has survived one Summer so far.
It's a acetone based glue. But it didn't melt the foam backing on the headliner fabric so that was nice.
I wonder how the water based products work?
In my experience over the years, when products go from solvent based to water based there seems to be a learning curve in the formula because the first generation formula rarely works well.
I believe the early amp guys used Hide Glue. Which seems like a poor choice since I know heat can affect that.
Usually tolexing uses the dry contact type gluing where you apply the glue to both the cab and vinyl and let that get tacky or dry, then apply the vinyl to the cab and roll it flat as you go to avoid air bubbles.
The other variable is the thickness or stiffness of the material used.
Cheaply made thin vinyl can be melted by solvent based glue.
Very thick vinyl can be difficult or impossible to work with on the corners and radiuses.
Anybody ever use the VOX black type tolex?
I'm thinking I want to build a head cab down the road that will match my VOX 2x12 speaker cab.
