Thanks to FF for the original idea of blasting steam away with jets of air during a neck reset! I wrestled with trying to make a "from-scratch" version of his, but the nagging issue was already using an old StewMac neck-removal jig that's worked just fine for years... although, of course, it had no air.
So, after a few false starts, I've jerry-rigged an air-blaster that attaches (and can remain attached) to the StewMac jig ...and saved a few bucks in the process. The plastic cable ties started out to be for temporary holding but they seem to work just fine on a permanent basis.
Nothing terribly complicated here, a capped-off PVC manifold with four 1/4" Loc-Line hoses & ends to aim at the usual suspect areas that tend to blush the finish when the steam escapes.
The end on the "driver's side" accepts a small vacuum cleaner hose end, with the vacuum cleaner set-up to blast air out instead of vacuuming-in.
BTW, Mike, how do you make your shop vac blow backwards? tom
----(hoo-boy, there's a hundred one-liners there, but I'll pass and take the high road :)----
Anyway, the vacuum I'm using is an inexpensive little benchtop/wallmount model from WalMart and the hose can attach at either of 2 ports, one on either side of the canister... one sucks, the other blows! Really, that's the only way to say it... and most shop vacs are set-up the same way, too.
Here's what I'm using... it's not pricey at all and works well. http://www.shopvac.com/wet-dry-vacs/vac-details.aspx?vacId=342&... The hose-port shown on the front is duplicated on the back, and that's where the air is expelled out.
Mine, sucks, doesn't blow .. was I shortchanged? ;-)
..thanks for the info..Tom
