Hi Roger,

I've got a question thats answer is probably obvious to everyone else but me. It would appear that as you slide your material over the blade it's sliding up a "ramp". How do you get an equal depth of cut on each side of the board? For instance, let's consider that we're cutting dovetails. Isn't the depth of the cut going to be slightly different on each side?

Clueless as usual (and currently in Pocotello, ID enroute to Sheridan, MT).

Mike

Mike,

That's a fair question......

By sliding up the "ramp",
if your referring to the pitch of the blade as it looks - at an angle to the stock as it passes thru the cut.....

The cut of the stock will be the height on both sides equal to the higher side.
Because the stock will pass thru to the highest point.
I'll take some close ups and post them over the weekend to illustrate my point.

also...... the pitch of the blade is adjustable.

Got it. I didn't realize that the material cleared the blade. Thanks, Roger

...as in it runs past the far end of the blade on each stroke.

......not always.

Concerning miters . . .
Depending on the miter cut, and the jig used,
one might clear the teeth, but not the blade.
(there is an angled cut on the blade at the end of the teeth.)



I'll take some shots on this subject later today.

On the subjects of miters,
for anyone interested in special rigging on the JMP, I just downloaded a long post on a working model of a 3-Point 45 Degree Miter Clamp Jig for the JMP

The thread is residing at the Jigs & Fixtures forum at BCTW.

Roger,
Is it possible to rip on the JMP? I don't mean just tenons, but perhaps rails & stiles. I'm assuming that there might be a way to set a fence to do it. I'm also assuming there's a size limit.

Michael,

Rips for stiles and rails?
Sure.

. . . . . . for a model or dollhouse perhaps.

The length of your rip is limited by the your ability to clamp the workpiece onto the moving table in order to make your cut.
Without actually checking, that would be between 6 - 7 inches - in all normal situations.

That being said, there could be a way to increase that a bit, depending on how creative you get with your clamping-jig-holding method.
I'm sifting through different rip "situations" in the coming days and I'll be showing it eventually on the Jigs & Fixtures forum on the BCTW site.

Keep in mind that you have a moving table that is approx. 8" wide by 10.5" long with a slot arrangement that is approx. 9" long minus your back-fence and forward clamp.
The blade tooth cutting length is approx. 14.25" and the maximum travel of the table is 16" (taking into account the length of the table.)

So creatively there is room to play, just give me some time.

One thing I will say is that the linear bearings makes the rips I do cut a lot easier than the dovetail sliders. Over the weekend I'll post some photos of small rips that I've done with spaulted beach.

Hope that helps.

Roger,
What I had in mind was some kind of continuous cut. I think I need to come see your's.
