My first job in the auto trade was working for a Mercedes shop. Back then (early 1970s) the exhaust systems on them had to first be fitted/mocked up in the car, tack welded, then pulled back off and welded completely. We got a LOT of oxy acetylene welding practice. An odd thing we discovered was that the wire coat hangers the uniforms came on made the best gas welding rods.
Fast forward to the 1980s and owning junkyards and cutting things up with a propane/oxygen tip saved huge money using propane instead of acetylene. You can buy propane cutting tips for most torches.
All that to say I'm still quite fond of torch work.
One thing to be careful about on that old rig from your dad is that the diaphragms in the regulators may blow out from old age when you first put gas pressure to them. Just be ready to shut down the valve in case of unexpected excitement.
