Topic tags/keywords: question i replaced knives in a boice crane 1400 joiner and made sure knives were well seated the length of travel the work pieced moved from first contact of the knives to release was all over the the place from one end of the knifes to the other the only pattern was the travel of the work piece was less away from the operator whats going on

I’m retired from the button factory Woodworks where I worked, as an independent wood worker. Setting up small shop in my basement and need help setting up my boice crane jointer. I replaced the knives; problem is when I rotate cutter head to move wood through the arc of the knife, I get different lengths of travel from one end to the other (laterally across knives). The specs call for 1/4”—3/8s travel of wood from point of contact to release of cutter head. Made sure knives were well seated—no luck.
So, Can the cutter head bearings be adjusted? Shimming the ways could be a possible fix? I bought this joiner because machines like this one are pretty much bullet prof. Can somebody out there show me the Way? I’m new to operating in a forum. Lets hope I’m doing this right

What do you mean “Well Seated”? Those knives ‘float’... they should not be sitting on anything, and you adjust them against the outfeed table. They do not have to be, or need to be, parallel with the cutter head – as long as they are parallel with the table.

BTW: I did the ‘movement’ method for a long time and always got mixed results. It wasn’t until I got a dial indicator that I saw just how far off that method can be. Do yourself a favor, get a dial indicator to set your knives!! You will be glad you did. You can pick up a decent set along with a magnetic base and different tips on Amazon for about $30. The replacement tips are really useful, as one is a large wide tip that is perfect for the knives; the stock tip on the indicator is usually a small ball bearing type and difficult to keep on the knife edge.

Also, are you sure your bearings are in good condition? The first thing I do with new to me used equipment is replace the bearings to make sure. Cheap insurance to prevent much more costly damage down the road. The bearings on that machine are pretty easy to replace, and the motor should be easy as well. I documented my restore over at the OWWM site, where you can find more info on the bearing replacement.

Cheers,
Brad

PS: Once you get the dial indicator, you will discover a ton of other uses for it besides just setting knives!

PSS: If you don’t already have it, the manual can be found here.

Some Boise crane jointers have a fixed outfeed. That can make setting knives really fussy.
Brads advises getting and using a dial indicator. I agree because that’s what I use.
First make sure your using the correct knives thickness and width.

Good Luck

Thanks folks, Thanks MrUnix. Learning that the knives float is a very important piece of info. I will buy my own dial indicator. I used a friend’s to set up my table saw using the PAL system. Forgive me, could it be better to set knives to Infeed table since that’s where the magic happens? The Outfeed table, after it’s set, will take care of it’s self. Happy my Outfeed table is adjustable. Replacing bearings is on the list.I have the Manual. It does bother me, though, that the fence does not contact the length of the Outfeed table. I’m making a false fence now. Thanks to
Brad,AJ,and btw. I feel better about setting up this old work horse. as ever,Wilss

The knives need to be from the outfeed. The infeed lowers and raise depending on how much you want to cut off a board. Usually 1/32 inch.
Here’s a very good instruction video on jointers.https://m.youtube.com/watch?v=ob3V5SVrqAw&list=LL&index=8&t=0s

Good Luck
