Mirrored scratchplate cutting/fettling


Recommended Posts

I’ve done a couple and it’s a bit of a nightmare. My ‘technique’ is to stick the mirror acrylic to my template using double sided tape. I then cut to about 10mm oversize with a jigsaw on the highest speed setting cutting really slowly. Then I finish to the template using a 60 degree chamfer cutter in my palm router, again on the highest speed setting. With one sheet of Perspex the double sided tape actually pulled the mirror finish off the back so check on a small test area first (in that case I covered the back with wide masking tape and then used the double sided tape onto that).

Other thing to watch out for is the swarf is very ‘sharp’ so leave the protective film on the front as well otherwise you’ll end up with loads of scratches (again, lesson learned the hard way). Of the two I have made, I have also made at least four rejects.

Try and find someone with a laser cutter! Makes for a much nicer edge and finish. 

 

Scan in your old scratchplate, create a vector image and boom! Perfect every time!
