Would this be a possible option for doing hot work?

Servus!

I didn't think that MAPP Gas got hot enough to do anything except set your shop apron on fire.

I would say no, but I am FAR from an expert.

I'm still thinking about getting one of those weed burners that run off the large gas tanks like you use on a gas grill, anyone try one yet?

I have one of these (not for any armouring stuff, just for around the house use) and the problem is not the heat, they get hot enough to cut through most metal I have tried. The problem is that the bottles are small, and don't last long. THey say the oxy bottles will last @ 20 minutes, but thats bull. More like 10. And they aren't very cheap when you have to buy 10 at a time.

I use Oxy/ Mapp on a regular basis, you can get larger bottles that will last a fair length of time, it works for heating and cutting without much problem. It is not very good for torch welding though. Patrick

Thanks for the info. DO you use a Rosebud tip (I think it is the term) for heating?

I will probably try it for a small amount of hot work. I can not have anything bigger in the house because of the insurance company.

I tried yesterday to do a little heating and working of a piece hot. Nothing fancy, just some simple dishing with a propane torch and I LUV IT! What a difference from cold work. Much easier to feel how the metal is shaped.

I am curious what do you use for as a cutting tool?

Pat - you say you are doing this because the insurance company won't like anything bigger....

My insurance agent never worried about my O/A system at all - 2 sets of tanks in the basement and he looked right at them.

As long as they are for a hobby..... They are probably safer than a wood stove or fireplace..

Wade,

Thanks, I actually didnt think about the hobby point of view. I have a small company but I actually do not sell anything thats made with the heating process. But go explain that to an insurance agent who just gives you the strange look when you say you make armour.

With the small amount of plate I sell, I will stop altogether and sell only chainmail. Then I can make a better distinction to them between my business and hobby wich will be plate.

Now the only one left to convince is my wife. Any advice on that Wade. ;-)

Actually - my wife never seemed to care.

She met me many years after I bought my torch (I got it when I was 16).

Seriously - I started assuming we could get away with this stuff when some friends (Polidor, Franz and Marc Rengarth - but those are names from the neolithic era, even farther back than the dark ages when I started) were trying to set up a shop in a garage in the city of Chicago. The insurance man didn't even blink about the forge, welders, etc. - but he made sure that they promise not to put in a woodstove or oil stove.

My torch was in the basement under the kitchen. I didn't even have the tanks chained up (I should have).

Torches really are not all that unsafe. Unlike fireplaces, you don't leave them alone and no matter what the worst case scenario, tanks are really safe if you aren't really careless.

Get a set, you will enjoy it.
