Laser cutter z axis linear bearing mount - After drilling the holes on the bridgeport mill I used this metric tap guide and a m8 tap to thread the holes in the plate. I am a little disappointed in how well the tap guide works, there is way too much slop in the guide to hold the tap straight. The guide itself is very well made just not snug enough. I guess this is due to most taps from different manufactures being a slightly different size, so it would be difficult to make a system like this that works with them all?
