Years ago I saw someone at a fair making name signs. Using a plunge router with some type of plastic shield around the circumference of the face plate. The operator could see most of what he was doing and the vacuum hose connected to the shield caught most of the sawdust.
Need to be making more signs and probably try to work some butterflies or dutchmen into some other projects.
Looking for a good plunge router and one of those shield units. Recommendations?
