Finish planing, helical and quick change knives2/2
I have a small wooden window factory and have been purchasing my poplar stock from a saw mill with a double sided helical planer. They let me cut my wood to length then joint/plane it for flatter boards. However, even when the Extrema planer is tuned in with fresh carbide the wood has “micro voids” and needs sanded or finished again. After much experimentation I’ve found my little Dewalt 735 cleans the surface nicely, with no further attention needed before priming/staining. BUT, it’s a hobbyist tool and the motor overloads during long runs. I need a stationary planer that gives the same finish as the Dewalt but is much more rugged. Also, I LOVE the easy with which I can change the blades in the Dewalt.
So, since I can’t get the Dewalt 735 with 7.5hp 3ph I need to find the next best thing.
I’m looking for a stationary planer with a) straight, quick change blades b) a smooth finish c) plenty of power.
Is the Jet JWP-15DX 15” 3-hp Planer the only one on the market with quick change knives like the bench-tops?
Any other suggestions?
Can ANY helical give the same quality cut as a a good straight knife planer?
Are you familiar with Tersa Heads? These straight knives are available in a few HSS and Carbide types, and have two edges on each knife. Tap them down into the head a bit, and they slide out the end of the head. Slide in the new ones and turn on the machine. If it takes more that 5 minutes, you should find another line of work.
These give a very clean cut; the HSS on Pine makes it shimmer. The carbide is more durable of course, but also very sharp.
However, it is always recommended that all wood, especially exterior wood, be sanded before any type of finish. The sanding provides a mechanical and chemical bite for the finish.
