In this video I fabricate and machine a new bigger riser block for my milling machine.

First job is to take the 4” block out of the milling machine to see how a new one needs to be made.
15mm top and bottom plates are cnc plasma cut out, 12 mm braces are also plasma cut out. These are tacked together before a 6mm outer ring is rolled in the rollers.
After the riser block is welded up, its put into the lathe to have the mounting faces machined flat and also the outer diameter is machined for a smooth appearance.
The bolt holes are then transfer over onto the new block, top side is drilled and tapped, bottom holes are drilled straight through.
Finished off with a coat of red oxide spray paint.
Hope you enjoyed the video.
Thanks for watching.
