How do you guys minimize the chip out of cabinet grade plywood when cross cutting dados in plywood. Cabinet bases and wall cabinets have dados cut into the sides for the top, bottom, and back. When I built the cabinets for the buffet, I got some chipping. Not enough to really concern me but I would like to minimize it as much as possible.

I used a stacked dado blade. However, I didn’t have a zero clearance plate but I have one now. Maybe a test run will help determine if something else is needed.

Note: I am not really interested in using a router because of the number of cuts to be made – too time consuming.

Just curious to see if you guys have any tricks or tips you can pass on.
Thanks
Mike

Score both sides of the proposed dado with a utility knife, or masking tape along the cut path.

Adhere a 1/4” piece of cheap plywood to it so that it is the surface chipping out.

The quality of the dado set makes a big difference….at the very least, keep it clean. Take light passes. The suggestions above will help too.

A good dado set with a zero clearance insert is your best bet. But “good” dado sets tend to run $250 and up.

The easy way: Set the blade to only about 2mm height and cut BACKWARDS. Then to full height and cut as normal. It looks a bit dangerous but is totally safe.

Hope this works?

I think you need a spankin’! :-)

I like Gene’s idea of scoring before cutting. That should be fairly quick with a simple jig.

The next project will probably be ten cabinets, 5 uppers and 5 bases. So that is forty cross cut dados. The bottom dado of each unit will be 1 1/2 up from the bottom and actually a rabbit on the top end of each base. The uppers will be 1 1/2 from each end. I can easily make a jig and score a line quickly before passing the piece across the dado. I would only need to score the side facing the joint that will be seen.

I appreciate all of your feedback. It is nice to get help and advice from those that know. No doubt I will be documenting the build as I go.

Kaerlighedsbamsen’s suggestion is perfectly sound. It works well and is quite safe.
