The DeWalt DW1150 is a cast iron jointer planer made in the 1980s and early 1990s. It was the successor of the DW50 jointer planer. It has a much better fence than the DW50, which was the weak point of that machine. It was succeeded by the DW733s, which is large the same, except painted yellow.
Cast iron body
The body is made from heavy cast iron, which is much higher quality than most other machines, both new and vintage. Its construction is relatively simple, so most models you will find on the second-hand market are still very useable today, simply because there isn’t much that can break.
The machine’s key features include the folding tables, which helps you maintain accurate settings even after switching between jointing and planing. It also has two feed rates (9 & 11m/s) for planing, which help with cut quality on difficult boards.
Changing the height on this machine is easy, because the handwheel is attached to the thicknessing table itself and operates very smoothly.
Replacement parts can still be found online. Be sure to also look for the DeWalt DW50 and ELU EPT 1151 and 1153, because those are identical machines for the most part and many parts are interchangeable.
Mortising table DW600
There was also a mortising attachment for the DW1150, called the DeWalt DW600. You can find the schematics for that here. I’m not sure whether it also fitted the DW50.
Note about the fence: Some machines still have the same sloppy fence as the old DW50, so be sure to check that when looking a buying one of these.
Replacement Blades: You can find replacement blades at Amazon UK (sold by Axminster), Amazon Germany, or on eBay.
