Woodworking #6 - The Jointer's Jumpin'

[psychomikeo500]

i read an article once about jointing with a table saw. you put a sacrificial fence on your saw and raise the blade up into it. then behind the blade, you put a thin piece of wood the width of the exposed blade and keep the board straight to that to joint an edge

Hi. According to this, especially the end of this video, I am decided about to build my own CNC router base. :-) Realize that feeling of timber perfectly flattening itself automatically during my coffe break :-) heh

I have a problem; whenever I use my jointer it creates a "wedge" shaped board, has anyone ran into this before? Email; justicejamesb@gmail.com

@LFWOL I try to avoid saying things like "always" and "never" in woodworking, lol. Always lands me in hot water. 99% of the time I go with the concave side down. But there are some instance where its more effective to go with the convex side down. Primary, with a thinner piece that just by virtue of pushing across the jointer, flattens out "artificially" from your hand pressure.

11:13 I really don't understand this point - if the timber is too wide to go through your jointer as it is, how does glueing it to an even wider board help?

[TheWoodWhisperer]

@danebdon because we are sending it through the planer, not the jointer.

[jumbo508]

@danebdon really how does that help

Good video, but I have to point out that your use of the word coplaner is incorrect.

Two planes can be parallel, but to be coplaner would mean that the board has zero thickness.

[GamingDrummer89]

With cups, I always have to put the convex side down. But I have to do it the other way with bows and twists. If I don't, I always find that the little bit of downward pressure I put on the board is enough (especially with long/thin boards) to press the center of the board flat only for it to spring back up to being bowed slightly. If I do it the other way, I don't put any pressure on the high spots (the ends) and those basically "float" over the knives and make the face come out perfectly flat.

If one's jointer is jumping, are its bearing defective? :-)

[TheWoodWhisperer]

@ChrisBowlas If its jumping too much, return it. :)

I would be hesitant to mark my boards with chalk. I don't know the hardness of chalk but to have it infiltrate the ways and/or bearings of my jointer could (again, depending upon the hardness) wear the machined surfaces prematurely.

[ChrisBowlas]

@hotwheelsp

I doubt that it would do any damage; for the chalk to mark the timber, it must be softer than the timber!

If you are still concerned, though, use a soft 3B graphite pencil.

thanks marc for this informative and detailed video. It is a great help for me to carry out lessons regarding jointing clearly...

[dchamberss]

Another great video Marc. Keep up the good work. Check out what we build sometime at.BradleyBrandFurniture com

[carykong]

Woodwhisperer---do you have a video on ways to turn your table saw into a jointer?
