Getting cutter to cut at a 90 deg angle to the table

Ok, so after 3 years I have came up with this and it actually works.I always had difficulty to get the cutter plum to the table and usually ended up with ridges on my projects.I had a disc cut about 120 mm dia with a 8 mm hole in the centre with 4 smaller holes to put screws through (didn`t use them).I then took a 1/2 inch shaft of a cutter that I don`t use anymore and attached the disc to it.I took the gadget and put it in the router and dropped it onto the table after I loosened all the bolts that holds the z-axis in place so that there is free movement ( keep in mind that I first skimmed a small section on the table and cut a round hole in the centre ) once the disc sits on the table it actually holds the z-axis plumb to the table.I then tightened the bolts holding the z-axis in place and there it is no ridges anymore.Hope it is self explaining. ( lets presume the glass is the table)

That is a pretty darn good solution Hennie.

I did something similar out of plywood (mine was a triangle) to square the relationship of the spindle to my Drill press table. I often rotated the drill press table for custom stuff and had a tough time getting back in plane. Great idea for the MM surface.

Now I have a few 45, and 30 degree step blocks drilled out to set the drill press table for custom stuff that works the same way in reverse.

Usually on a drill press, I use a 123 Block and a 3/8" rail in the chuck.

Ross the 120 mm disc worked well.One can surf on a 600 mm disc :)

I think I'll shrink my big idea back to your more respectable 120mm :)
Nice tool by the way.

Well if you own your own broom you MUST be clever.

Kobus it is for rent if you need to use it.You just need to get on the broom and harry potter over here and get it:)

Just to give you more ideals or how to improve upon. I want to say they use to make a 1/2 shank one but I cannot find it anymore.
