- (Well, I *personally* don't want my buns soldered off, thank you very much! ;-)

- Hmm. Synthetic motor oil, eh? That might have been better than what
- we did - we used cooking oil because of not wanting the (assumed) noxious
- fumes we expected from motor oil. The main problem with cooking oil was
- that it has a very short "hot enough but not so hot to burn" range - you
- have to keep it almost smoking but not quite....
-
- I would also think, now that I pause to think about what we were doing
- (yeah, pausing to think about 10 years after the deed is done!), is
- that the solder pot would have been a MUCH safer way to go about it -
- you could clamp the solder pot down, you don't have to diddle with
- the stupid pan edges (I remember wearing my leather motorcycle gloves
- in order to be able to handle the boards - don't try this at home,
- kids!), stuff like that. I don't remember if we tried to heat only
- the board or if we stuck the entire assembly under the oil - I think
- the former, and I vaguely recall it was NOT a simple matter to get
- enough oil in the pan (NOT exactly the flattest surface around)
- to cover the pins in the middle AND the edges...
