Re: Gas forges/torches

For heating and cutting but NOT welding I strongly suggest an Oxy Propane rig over Oxy Acetylene; *much cheaper* and easier to deal with propane than Acetylene. You do need the correct tips to use it however. (It is as mentioned in-appropriate for welding.) As for scrap yards my favorite is a quite ...

Re: Wrought iron from the Globe Mills

More than 12 points phosphorus makes the iron brittle when worked cold, Cold in blacksmiths terms! Too much sulfur makes for hot short iron---iron/steel that will fall apart when worked too hot. Phosphorus is a hardening element; not as good as carbon but many of the bloomery irons were high phospho...

Note once you have a good burner forges are rather trivial---I built my last one one Saturday morning for US$2 no welding required fanciest tools were an angle grinder and an electric drill.

Re: Can you identify this armour and help solve a mystery?

Remember stoutness implied wealth as did a lack of a tan on women---they didn't have to work out in the fields in the sun. It's the paleness of factory work that made tanning an indication of leisure time and thus wealth in more modern times.
