The articulating spacer for the SX2 is a design by Donald Bird that was posted on CNC Forums<\/a>.<\/p>\n

<\/a><\/div>\n

The plans are all imperial, but this is a metric sized mill, so I converted all of the dimensions to metric and drew it up in Fusion 360<\/a>.
This first piece is the front mount plate that is 110x88x19mm.<\/p>\n

<\/a><\/div>\n

I started off by squaring up a suitable piece of aluminium.<\/p>\n

<\/a><\/div>\n

It was somewhat rough on the rear side, so I decided to flycut it flat.<\/p>\n

<\/a><\/div>\n

Next I drilled the mounting holes 8.7mm, then counter bored 14mm to a depth of 9mm.
The centre hole is about 10mm at this point.<\/p>\n

<\/a><\/div>\n

The centre hole was enlarged to 16mm and then counter bored at 63.5mm to a depth of 0.5mm.<\/p>\n

<\/a><\/div>\n

The part was then flipped over and I started cutting the offset pocket with a 3 flute 10mm carbide endmill.
This shot was taken after clearing the initial pile fo swarf. <\/p>\n

<\/a><\/div>\n

 Next up milling off the central chunk to complete the pocket.<\/p>\n

<\/a><\/div>\n

 followed by a cleanup pass to the final dimensions.<\/p>\n

<\/a><\/div>\n

 Clearance chamfers were then cut with a 6mm carbide endmill and the corners squared off.<\/p>\n

<\/a><\/div>\n

 The part was then clamped to the table to allow enoughh height for drilling vertically.<\/p>\n

<\/a><\/div>\n

 The central hole was drilled through and tapped M8, the outer holes were drilled through 6.5mm and counterbored 10mm to a depth of 9.5mm.<\/p>\n

<\/a><\/div>\n

 The finished piece, just needs the blue marker cleaning off.<\/p>\n

<\/a><\/div>\n

Those with keen eyes may notice the hole at the bottom where I started drilling the M8 hole on the wrong end!<\/p>\n","protected":false},"excerpt":{"rendered":"
