- My Delta 12" planer and 6" jointer are well overdue for blade
- replacement. I see several options for approaching the task and
- am interested in learning about the experiences others have had.
- Here are the choices I've identified so far. Maybe others can
- be suggested.
-
- 1. Use the trial and error adjustment procedures in the manuals
- supplied with the machines. Maybe this isn't too bad, I don't
- know. My reading of the sales brochures and articles below lead
- me to believe that this is tedious and not too accurate.
-
- 2. Magnaset. These are widely advertised devices that use
- magnets on a pair of arms at each end of the blade to hold the
- blades in place while set screws are tightened. Sounds
- straightforward, but the cost is high. Really high since
- separate Magnasets are required for the planer and jointer. My
- just received catalog from Woodworker's Supply has these listed
- at $71.95 for the planer and $41.50 for the jointer (assuming
- steel and not carbide blades). Each is a substantial fraction
- of the cost of the planer or jointer itself.
-
- 3. Dial indicators. The use of these for setting planer and
- jointer blades is described in issues #70 (I haven't seen this
- yet) and #87 of FWW. This seems attractive because one dial
- indicator can evidently be used for setting the blades of both
- machines and can be useful for other purposes too. I don't know
- the cost of a dial indicator of the type used in the FWW
- article, which includes an electromagnet to hold it in place.
-
-
-
- 4. Knife Alignment Sensor. This is advertised on page 5 of the
- Dec. 92 issue of FWW. The literature sent to me by Chesapeake
- Enterprises, who sell the device, shows that it senses
- electrical conductivity via sensors held in place by magnets --
- you raise the blade until contact is made and a light flashes
- and then you set the screws to hold the blade. Unlike the
- Magnaset, this has is a configuration with one arm that extends
- over the blade, so separate measurements would seem to be needed
- at each end of the blade being set. I haven't used this
- contraption, but my guess is that some repetition must be
- necessary, with the device being moved from one end of the blade
- to the other until the blade is set as desired. Seems like a
- reasonable idea, and the single device can be used for both the
- planer and jointer. But it's expensive at $99.95.
