Zero Clearance Plate

[conwaygolfer]

Is there any benefit to a zcp when cutting 45* angles? If so, how could it be made, considering at the rear of the blade is the location of the riving knife.

I made one from 3/4 oak for 90 * cuts. It lasted about 2 years. After cutting a slot in the rear for the "knife", there was only about 1 1/2 in. left to hold it together at the front. I guess it finally got tired of me removing it and it split apart at the front.

Is there a better way? Thanks for your advice.

sure you can make one, with the BT3s tilt the blade, lower it below the table and raise it through same as you make a 90 degree plate. Be careful of trapping the blade so it can't turn freely when started or you'll be breaking belts.

Its less likely to break if you make it of a grainless material... probably still have to be careful about bending it depending upon the material.

as for benefits, same benefits - but I think less obvious.
Reduced tearout,
dust collection
keeping cutoffs out of the saw body.

I don't think any of them are so bad with 45 degree cuts I've wanted to make a special 45° ZCTP, so I don't have one.
mostly you get a sharp edge anyway, and cutoffs are wedge shaped and less likely to fall in.

I use the stock plate, but add a piece of blue painters tape over the slot. Put it on while the blade is retracted and extend beyond the front of the table, raise the blade to cut height. Tape lasts longer than you think it would. Standard disclaimers apply. YMMV.

Thanks for the input. Think I might try the tape.
