Hi Guys:
I have a Craftsman 4 1/2” Joiner-Planer I got from a neighbor (it was free so I couldn’t turn it down ). It is missing the guard but it does work, although it is a little loud. The blades were dull so I purchased a new set. I was surprised but Sears still has the blades available.

My problem, and question is does any one know how to adjust the blades on this? I got them close but one or both of the blades is slightly eschew. I can tell when I make several passes on a board the cut becomes increasingly crooked. I can compensate by alternately flipping the board end for end but then I am going against the grain and get tear out. When I try to “level” the blades I have a hard time lining it up when the blade assembly wants to rotate and I can’t find a way to hold the assembly firmly. Also, when I tighten the blade hold down screws, the blade shifts on me!!

I cuss a lot!!l

I can’t find a manual on this so does anyone know how I can adjust these. I know…I should buy a REAL planer but like I said, it was free!

Thanks for your help
Bill

I had one of those loud things for a while. It was also a freebie. I even made a guard for it but like you, I could never get the blades right and eventually threw it out. I don’t think that are built well enough to do anything but ‘get it close’.
Now I use my router and a split fence for jointing. Been happy with that ever since and I really don’t intend to get a jointer anytime soon.

Make a pair of small wood wedges about 3/8” square on the wide end.
Use these to hold the cutterhead still. It takes a bit of fussing. Softwood
is probably better for the wedges.

Setting knives accurately without some sort of magnetic jig (or hold-down
jig on a spring-loaded cutterhead) can be frustrating, but pull up a low
stool, get some good task light on the jointer and take your time
and you’ll get it done.

The blades being off by even a fraction of an inch is just as bad as it being off by a mile.

I use a dial indicator with a magnetic base. Like Loren said, “pull up a low stool” because the devil is in the detail. The 4” jointer I have uses three set screws to hold each of the three blades in place. I lock the center set screw and make the fine adjustments with the outer set screws until it is as perfect as I can get it. When you get a good measurement on one blade, repeat on the other two blades.

I remember seeing an in-depth write up on this subject in Wood Magazine but I can’t seem to find it right now.

Bill, have you got an old speaker? Heat to magnet with a propane torch just a bit more that you can touch. tap with a dead blow plastic hammer and the magnet will pop lose. DO NOT let it hit the floor. Cool and remove any glue left on the magnet and use this to hold the blade for tightening. The bigger the magnet the better. Hope this helps. Rand

Thank you for all your help. I don’t have a speaker to get a magnet off of but that seems like a really good way to hold the blade. Looks like the wedge idea may be the ticket.

Bill, Here is an article by Tom Hintz that I found to be pretty helpful in setting jointer knives. What you have described sounds pretty normal to me. If the knives are off even a few thousands then you will have the problems that you are describing and, the knives will move when the gib screws are tightened unless you put downward pressure on the knives to hold them with a wood block or dowel while tightening the screws.

SIMPLE made guage.Plane a piece of hardwood about 12” long to use as guage.
Mark a line on the stick’s face where it crosses the edge of the outfeed table. Rotate the cutterhead slowly so the knife passes beneath the stick. If the stick doesn’t move, the knife is set too low. If the knife just brushes the stick, it’s flush with the outfeed table—which is still a hair too low. Ideally, you want the knife to drag the stick aout 1/8”, more than a 1/16” but less than 1/4”. This indicates the knife is a few thousandths proud, and your jointer will work just right, both now and as the knives wear toward dull. Move the setting stick to the near side of the outfeed table and make sure the knife drags the stick just the same amount to guarantee it’s parallel to the outfeed table across its width.
Repeat this process till all your blades are equal.

It appears that the Vintage web serve was down, but it is once again working.
