The difference between 60 and 240(iirc) degrees is quite substantial and it's very safe till you get to smoking stages of the solder then you don't have much time left.Originally Posted by T 20
Ah, very interesting but two of the old guns I'm bluing at the moment have cylinders which are sealed to the breechblock with solder and I'd be loathe to go anywhere near them with a blowlamp.
Besides which I seem to have cracked the job by switching from acid fume bluing to rust bluing using Ammonium Chloride --- I managed three rustings today.
One of the items I'm bluing is the barrel weight for this rotary pistoned HW35 which should finish the front end off nicely.
All the best Mick
You'd have to be a numpty to bugger that one up.
I use a laser IR thermometer to avoid that one.
