I tried several alternative for an Apron SWarf Shield:
I firt tried the?:
This is held in place by Neodymium magnets, but is a little thick (and the magnets gather steel chips). Also, I'm not sure if they are still in business, even though their website is still up & running.
I then tried the?: While their current offering (above) looks like it is Aluminum, mine was thin plastic sheeting and I used a bead of Permatex to attach it to the Apron. This worked well, but the left edge tended to grab on my telescoping lead screw cover, so the last time I had the Apron off I made one from 0.010" brass, drilling & tapping the apron for M2-0.040 x 3mm screws (didn't use drive pins because I want to be able to get to things later):
The lower left corner is secured by the telescoping lead screw cover receiver which mounts using the M4 tapped holes (added when installing the cover).
