DeWalt DW733 planer blade sharpening and setting.

[MarkG]

I have a DeWalt DW733 12.5" planer and have had it for years, but haven't changed or sharpened the blades yet-----one of those tasks I have put off and dreaded for some reason.

I have no problem sharpening knives, but that's different altogether!

To anyone who has this model planer, what have you done as far as sharpening and/or replacing the blades? I know there are countless jigs, fixtures, gizmos, etc. available. It's a task I know you have to get right if you want good finishes out of the planer, and I've probably put it off too long! :S

BTW----I have a continuous 'semi-permanent' long table running through it and the whole thing is mounted on a bank of rolling cabinets.

Thanks for any tips or for sharing your experiences with this planer.

Tagging along on this one. It seems to me for a quality finish you need a really good grind on your knives. If it were me, I'd bring them to work and do it on the surface grinder.

I use my 6x48 belt sander with a 150 aluminum oxide belt, I made a beveled guide out of white oak I sharpen my 20 inch planer blades and my 12 inch planer blades this way. I do a quick hone on an Arkansas stone after.

It works well, you may need practice to get it right I have been sharpening my tools for 40 years hate having a shop do it, they grind way too much off takes me about 25 minute's to do my 4 20 inch knives.

I keep a spare set sharp so I can sharpen on my down time.

These work well for blade alignment when replacing or resharpening.

The bench top "lunch box" planer blades are so thin and narrow actual sharpening is just about impossible. They should also have index holes so there is nothing to align. It's a totally different setup than a cutter head with gibs.

That totally depends on the model, I have a "lunchbox" delta 12 I bring to job sites and use in the shop for thin stock, the urethane in and out rollers leave no mars. The knives are double sided no holes and the head has gibs, the knives are supposedly disposable a few quick swipes and they are sharp again thin as they are.

Just have to know how to sharpen them.

Any planer I have used, index holes or not should have a alignment jig some are magnetic others are hold down by hand for setting knife height.

For double side knives a good trick is to mark the dull side with a sharpie when flipping.

Yeah the urethane rollers are the reason I kept my delta lunchbox.

Not sure how a jig can do anything on a index pin setup there should be no play or any ability to move. Further the times I've used a magnetic knife jig on a gib gead, I've still gone back and had to adjust the knives once measured with a dial indicator

Here is the Dewalt manual blade change section, no jig no adjustment. They are double sided knives so just flip them for a fresh edge

Ok never used that model, I have a hitachi that has locator's but they are oval so it still needs a knife setter.

I will try to remember to take a picture of my knife sharpening jig for the sander.

Sharpening jig, bolts on and off the sander I hone off the wire edge on a Arkansas stone, works well for me.
