Just would like to share a simple way making a constant chamfer on the side of plaplate .
the chamfer i need here is 45degree on 1mm plaplate , so by math it's D1= 1mm , D2=1mm
Option A : Using the sharp edge of caliper, lock the measurement n just scribe along side .
Option B : Ruler marked up n down scribe a line or just with pencil.
i always prefer scribe with caliper , job done in secs with constant width . But only if u had invest a caliper (RM40 China bansai bansai ban ban sai !! :P)
Just paint the side with white board marker
Slice off the sharp corner. Dont need to be acculate , as long as the cut out not touch D1 & D2 marking.
1- Ease the next scribing process , which always happens where over scribe or accidentally slip off .
2- Less plaplate to scribe or to sand off , save ur time safe ur lung.
Just hold the cutter perpendicular to the plaplate on the chamfer n scribe with light pressure.
after the scribing , it might give u a "step" rough surface where you press too hard during scribing.
So Sanding is the only way - file then sand paper
Chamfer plaplate strip glued on.
