I had a call a couple of days ago to say that the Data General 6220 5Mb Winchester Chassis was ready at the shot blasters. On collection I was amazed to see just how much damage the rust had done to the chassis. With all of the oxidant removed the chassis revealed a lunar type environment – some of the craters are 2-3mm deep!
It’s a good job DG used plenty of steel for the base! Another few years and I think it would be sporting some extra ventilation 🙂 The entire restoration blog can be found HERE
So if you’re looking for someone to clean or polish your metal I thoroughly recommend Pro-Polishers in Oxfordshire, UK: http://www.pro-polishers.co.uk/ Gary and his brother Dean did a fantastic job on my chassis and are very well regarded, so much so Formula 1 teams use them for their shiny bits!
