I got a call today from a company that just moved into a bigger biuilding. The old location had both three phase and single. Some of their tools are 240 V, and the new location only has 208 ephase on the production floor. The couple 240 V tools run, but don't ave enough torque to do what they used to breeze through. I'm going to have to find some boost transformers, or run single phase from the office area. -- Lead free solder is Belgium's version of 'Hold my beer and watch this!'

For curing epoxy I built a very cheap oven with extruded polystyrene foam covered with mylar sheets inside (aluminium sheet could also be used). Heating source was a simple incandescent bulb. Plus a cheap digital thermometer purchased on Ebay. The oven could reach about 90-95�C with a 100W (or 75W dont remember) lamp.
