Labor surcharge for cleaning old work
$24.00 each (nominal)
This is a charge for the labor involved in scraping and stripping non-factory adhesives and materials, and then typically painting baskets that were scraped to bare metal, when rebuilding parts that have been previously rebuilt or refoamed.
It is a tedious process, often involving scraping away at unknown glues - typically contact cements supplied by foam surround sellers - that take much, much longer to remove than the much more appropriate materials and quantities used in the factory.
There are not many old woofers that I have to do this with when it occurs - principally it is the odd or "unique" dimensioned woofers and midranges used in the following models:
I just did one such woofer to come up with the price. I had to remove the cosmetic foam, which was glued with a copious layer of contact cement to the new, sturdy foam below (these were done, badly, recently - two worked ok, two rubbed). Then I have to scrape that new, strong foam as much as I can out of the contact cement that it was embedded in. Finally when that was done I had to soak the glue with Methyl Ethyl Ketone under a fume hood, wearing appropriate PPE, in multiple stages until the glue was completely removed. This exposed the painted surface below, but also a lot of bare metal that the prior "repair person" had left scraped and raw. Some of this was already rusting.
At that point a light spray with Rust Reformer paint/primer will make the part ready for where it would have been after a two-minute cleaning had it been only factory adhesive and the decayed original surround.
Twenty minutes at the current labor rate is what I will charge if I have to do this to rebuild a part. This is actually generous of me, which is a bit risky with my time except I don't think it is going to come up much. If it happens too much I may have to adjust that figure. I might charge less for the midranges - they are half the size, which does reduce the work required.
