Default 45deg chamfer fence

I need to put some 1plus inch, 45deg chamfers on some (full) 1x3in strips. Seeing as how I donít have a large bit, I thought Iíd try to use a straight bit and an auxiliary 45deg fence and some light passes. I made a triangular fence that would face the table fence and allow the work to be pushed past the bit at a 45deg angle.

I took repeated light passes. It worked, but I canít help but feeling there is a safer, better, simpler way to accomplish this. Iíd appreciate comments and suggestions.
Thanks
Dick

Iíve included some pics
1. Shot of the table fence, aux fence, and the chamfered strip (after it was cut)
2. This is my aux fence. I made if from some scraps I had. The multi layered pieces and the slot are the result of the scrap piece- nothing to do with the design.
3. Wide shot of the whole table setup. The aux fence is held to the table fence with a piece of corian and spring clamps.
4. End grain shot of the finished chamfers.

Dick, as long as you were using a push stick and your fence is set up as a jointing fence so the outfeed section limits the amount of the cut you got it in one.

Hi Dick

You're emulating the way this job was tackled in commercial shops on large (spindle) moulders before the more widespread availability of tilting arbors. Traditional-style rip saws don't have tilting blades, either, but instead rely on a tilting fence which achieves much the same sort of result.

On a safety note the only thing I could suggest is that you make the angled bed piece longer so that you are supporting more of the material in cut

Regards

Phil

Default 45deg fence

Thanks guys,
I tried the jointer fence setup, but it didn't work that great. I was probably in too much of a hurry and didn't get everything adjusted correctly. I ended up taking the spacer out and set the bit for a shallower cut and lived with a little snip on the ends.

The fence was "long enough", but you're right- If I need to do more of this I'll make a longer fence for better support.

Thanks for the quick responses.
Dick

Default 45 degree safely cut

Hi Dick, I believe Mike touched on the key component, the push stick. Try designing one especially for this task to push the jig and the workpiece at the same time.

Hi George

The jig should be fixed to either the router table fence of better still the router table and the material pushed over the top

Phil you're right of course but I didn't see any easy way for him to fasten it to the table or the temporary fence he made with the Corian, so my thought was to push both together with the special push stick on the end and his hand hold guiding on the angle jig. Not the best answer I know.

Hi George

That's a fine way to do it without a bigger 45 deg. bit on hand..

Hi George

Actually you might be surprised at how strong a hold a few blobs of hot melt glue can have on Corian. It's often used yo fix temporary plywood or MDF cramp (clamp) blocks when pulling a joint together on an installation job. Holds well and knocks off cleanly with a sharp thump from a steel hammer

Default 45deg fence

When I did my cuts, the fence did move to the left (push direction) but the Corian held the fence solidly against the table fence. I agree that a longer fence would be better and safer, but like I said, I used scrap that I had on hand.

If I have to use this setup again, I'm thinking another stick IN FRONT of the Corian and left of the aux fence. This could be clamped to the table and stop any movement resuliting from the cutting passes.

Great idea about the push stick- Obvious, but I just didn't think about it.

This forum has been a great resource for ideas and answers!..

Thanks
Dick
