Slot Cutters Create perfect slots for splines in your glue-ups, or make t-slots for your own slat wall. These router bits by Whiteside are 100% made in the USA, rated #1 by Fine Woodworking magazine, and guaranteed. Cut slots for biscuits with a slot cutter mounted on an arbor that’s equipped with a bearing. Cut a continuous slot on boards thicker than 3/4 in. If you want to make biscuit joints, you don’t have to buy a biscuit joiner. In most cases, a router equipped with a 5/32-in. Slot bit can cut perfect slots to fit the biscuits. How about cutting the slot in a square blank of wood then turning round would be easier to hold and cut. Or Laminate the blank from 2 pieces of wood with a 1 x 5mm rebate cut in one piece. This would ensure that one edge of slot would be in line with centre.

Cut Deep Slot In Wood

  • I will need to repair the bottom of a few exterior wood door jamb. Moisture from driving rain has penetrated and caused wood rot at the bottom.

    There is visible rot at the bottom four inches or so. I removed all the loose wood and cut back as high as 12” to get to solid good wood. Putting in a new prehung door is not an option right now.
    I have rebuilt the bottom 12″ of the door jamb and stop. No problem.

    The only issue is the original door stop has a precut slot in the door stop for kerf weatherstripping. I need to make a similar slot IN PLACE in the new door stop.

    How would you make such a slot? What tool? OMT? Router? Dremel? What blade or bit?

    Thank you.

    Sounds like they needed a new entry door.

    How deep and wide is the required slot?

    I say 1/2″ deep and the width of slot is about 3/32″, about twice the size of a OMT wood blade.

    Try stacking 2 OMT blades to get the thickness or just cut the slot with one and ride the side to get the desired width.

    Cut the spline off the weather strip and glue and brad nail it in place.

    I was actually thinking about doubling the OMT blades and see if that would work on a scrap piece of lumber. That would be an ultimate hack haha.

    Does that work????

    Edit: just tried…nope. That would have been nice!

    I think I would use a thin kerf circular saw blade to get most of the groove, and the OMT to finish it. Might be a little wobbly, but it’ll be covered so it won’t be too obvious.

    Dremel type rotary tool with router base attatchment and slot cutting bit.

    Router with an edge guide.

    I was thinking dremel purely for the size. Could get the slot closer to the threshold before the base bottomed out.

    You mentioned it has to be cut in place, you mean that stop kurf?
    Can you measure and then cut before you install, I’d do like Sorpa mentioned router and guide

    I’m doing the same thing now…. only I remembered the kerf in the stops.LOL
