Router table kickback question

**spartan** · 21st November 2008, 12:52 PM

I'd like to tap into the collective wisdom if I could....

I was doing a few test cuts on the router table last night. I had a small piece of timber perhaps 120 x 70mm - off pine. A brearing round over bit in the table - I was running it through to get an idea what a good height above the table would be to achieve the 'step' I was after.

I was using a starting pin. Feeding into the direction of turn of the bit. I had a couple of instances when I was working with the end grain of timber, and at corner, starting the cut where there was a gripping and the router wanted to push the piece between the bit and the starting pin.

I checked a couple of things and noted that the router TRA001 was set 1 - for speed. I turned it up to 4 and I didn't experience the problem again.

so was I experiencing true kick back or was the bit likely stalling, restarting etc?

I did experience the bit stopping before I turned it up...

Hi Spartan. I was hoping someone more knowledgeable would have replied to this first because I am not exactly clear about what happened. It sounds like, if you were cutting end grain, that the edge being done was only 120mm long. I think that would be hard to control against a starting pin - so easy to get the angle a bit wrong and have the cutter grab and swing the board a bit so it seemed to head between the cutter and the pin. My thought is that for the end grain cut you might support the board on the mitre gauge set at 90 degrees and run the end of the board against a fence. Thats how I do it anyway, and an advantage is that you can insert a piece of scrap between the workpiece and the mitre gauge to reduce tear out if that is an issue. I'd like to know what more experienced routers do.

Sounds like the bit was grabbing due to a slow bit speed and maybe a too fast a feed of material.

Normal feed orientation is against the rotation of the bit. With the rotation can lead to the workpiece being snatched out of your hands and shot out at a great velocity.

If you have slots for a pin in the table make sure that the pin is located so that the lead into the cut is against the grain as Mick has stated.
A lot of production router/shaper tables provide for a couple of threaded pin placements which may depend on the motor rotation (particularly if using a shaper type of table)

Some router tables provide these pin locations as matter of course,simply with the router stopped and unplugged rotate the spindle which show the cutter coming towards the timber rather than away from it.

Cheers

Definitely feeding in the right way, with the woodpecker plate, and rings it hard to get that part wrong.
