I bought this 1987 Invicta/Delta (made in Brazil) jointer from the retiring owner of a cabinet shop. It had lived a pretty rough life, but I really wanted a DJ 20. I now have more money invested in this 19 year old machine than a new G0490.
I was able to buy a new base and motor for less than the cost of replacing the motor alone. The new base is the current version of Delta "Grey" (there are about 50 variations of this color), anyway the old jointer was the blue/gray and didn't look good on the new base.
I had some paint made to match, disassembled most of the jointer and refinished. It turned out OK.
The side benefit of this project was, the jointer (as I bought it) had a 1725 rpm motor, giving a cutterhead speed of about 2700 rpm, the new motor is 3450 which gives a cutterhead speed of 5400 rpm which is just about right.
