Part 1: Design, CNC Parts and Positive Stops

In this video I will make a pivoting base or stand to mount the head of a cheap Mitre Saw, with the usual positive stops. This will be part of a series, and the videos will be available on a DIY Mitre Saw playlist. I am also introducing the idea of making machines on a CNC machine.

The sketch up plugin I used was: goo.gl/3Dl71d

00:02 Introducing the build.
01:14 Cutting a miniature maquette / prototype.
02:03 Testing fit of pieces.
02:35 Making the positive stop.
04:42 The pieces in birch ply.
05:22 Adding ball catch.
06:27 Installing saw motor.
07:29 Re-installing saw motor.
08:09 Fence positioning
08:50 A natural end.

Part 2:  Fence and Angle Locking Mechanism

00:19 Planing the location of the fence.
00:32 Screwing the base to the turning collar.
01:10 Cutting fence pieces.
01:30 Double checking line.
01:57 Gluing fence pieces together.
02:33 Drilling and screwing fence to base.
04:48 Fitting rubber feat to base.
04:55 Making locking handle.
07:22 It worked.

Part 3: Zero Clearance Insert, Dust Flange and Increments

00:05 It’s a bit stiff, I should sort that out later.
00:26 Checking how accurate my angles are. Seems good enough.
01:11 I use this flush trim bit to router a channel around the edge of the base, so dust can fall.
02:08 CNC’ing the female part of the zero clearance insert.
03:11 CNC’ing the male part of the insert plate.
04:42 This insert is a little shallow, but that is not a problem.
06:26 Extraction and making the dust baffle.
07:40 I missed a stage – mere mortal.
08:40 Cutting the rubber flange.
09:27 TEST CUT
09:44 Increments
10:18 Using a razor to smooth the paint job – which I done off screen.
11:33 Final Thoughts.
