|Clarkson Mark I/II/III Tool and Cutter Grinder - Home Made parts and Modifications|
↓ The Universal Head bracket is scratch built and is 20mm lower than the factory part. Here's how it was assembled and welded.
↓ The Universal Head bracket is graduated.
↓ Sharpening a 50mm drill bit.
↓ Sharpening a 5/8th drill bit. The finger was awkward to use on the smaller size drill bits.
↓ The rear stop mechanism.
↓ The block is drilled and tapped. The finger assembly is attached to the two inline holes on the top.
↓ The zinc block was not quite long enough, so a 'locking block' was attached to the end of it.
↓ The 'locking block' is attached to the main block by only 2 socket screws, due to lack of space.
↓ The block is aligned to the index marks on the bracket.

↓ Split Cotters are used to lock the rotating parts.
↓ The base plate "D" is a little bigger than the others. The 20mm diameter CRS round was welded to the first "D" and the face that mates with the second was faced off.
↓ A second stub was welded to the second "D" which was faced off to mate with the first using a stub of CRS locked with the split cotter.
↓ The third "D" with the second split cotter with the vice mounting plate welded to it.
↓ The vise is a 1" screwless from CTC Tools which is big enough for most lathe tools found in the home workshop.
