Toolpost Grinder |
There have been several times when I've wished for a toolpost grinder to finish a shaft just right and to close tolerances. I debate whether to buy a used Dumore or Themac on eBay or try to fabricate one as a project. Simple ones are really easy to make and just involve lashing a suitable Dremel or hand grinder to the post in some way. More complex versions involve fabricating a spindle and replicating the style of the commercial TP grinders. I am really tempted to work on a spindle for one. It would be a good warmup should I ever choose to make a more ambitious spindle, perhaps for a lathe or a mill. Meanwhile, I am collecting photos of TP Grinders others have made for ideas.
