Traveling Sherline Show
Backside Cutoff Tool Holder
A back side cut off tool holder has a real advantage in these small machines. So, I decided to build one for the Sherline. I found plans for one on this site. I copied these but for using a T-slot key on the bottom rather than a bar on the side to keep it square. The result is as shown:
It follows the design of the stock Sherline holder, as well as the design mentioned above. A pocket is cut for the cut off tool to sit in. The slots allow the screws to tighten and pinch the tool to hold it in place, due to flex of the top. The center stud goes into a T-nut holding the holder to the table.
I also made a riser block for this cut-off tool. It's shown below with and without the main cut-off block.
The part on the left is a riser block when using the 1" head stock riser block. It also has a T-slot key on the bottom. Two counter sunk cap screws tighten the block to the table. Then the cut off holder key fits into the slot in the riser. The bolt that normally holds the holder to the table then holds it to the riser block.
It works well but requires the part to be solidly mounted in the spindle. It works better than the stock front side tool.
