Quick change planer blade system7/3/15
Can anyone relate their experience with the ESTA Dispozablade on a professional grade planer? I'm considering purchasing a 20" planer, (SCMI), and using the quick change system. Will I be satisfied, or is the only truly good system a built in Teresa head?
About 10 years ago I purchased an Esta Dispoz-A-Blade system for my 12" Model 100 Powermatic planer. I couldn't get the knives set at better than .01" to .02" accuracy across the width of all 3 knives.
I called and was told that for the typical user that was a pretty good setting. With a dial indicator and my old steel knives I had always managed .002" to .005" accuracy.
Since then I think they've improved their indexing system. I on the other hand quickly went back to my old steel knives until finally putting a Byrd Shellix head on the planer 3 years ago.
By the way I have to rotate those carbide inserts for the first time this coming week. Of course we don't do the volume of material through the planer that the typical shop would run but it still strikes me as pretty amazing.
I also tried a set many years ago. Also had a negative experience. Used them on a 24" Wadkin planer. They were flimsy and bowed as the gibbs were tightened, sent them back. Would not recommend. Go with the Byrd, Tersa, or Terminus
I bought my SCMI 20" used and to my surprise it came with a Tersa head. It takes about 6 minutes to change all 4 knives and resume work. Also allows me to keep my carbide set at the ready for any work with Teak. The old school version of this is my 12" Oliver jointer with a sharpening attachment that sharpens the knives while still mounted in the head (bolts to the outfeed table). It was built in 1944.
