I did a modest amount of scraping 20+ years ago to true up a small Chinese bandsaw. Scraping, hacksaw and files were my only option at the time. While not economic, the skill was worth the time spent. And the saw cuts true and will slice dime thickness pieces from bar stock.
For lack of practice, I have done a number of projects recently using files rather than my milling machine just to maintain the ability to use a file.
I bought a small lathe which I would like to scrape true and tune for precision work. Amazingly a 0.0001" indicator on the inside of the spindle taper does not move at slow speed. It increases a good bit when I speed it up, but I plan to address the imbalance by building a dynamic balancer and balancing the spindle plate. My assumption is that for precision work I'll use fixture plates or collets.
To scrape the dovetails I need a spotting reference. Is there an economical source for these or do I need to make my own?
If I need to make my own, what's the best material? I've got some ductile iron bar I can slice a slab off. That seems as if it would be the most stable material.
This is a warm up exercise for overhauling my Clausing lathe.
BTW I have a copy of Connelly. I've not read it in many years. But I did read it long ago.
Thanks,
Reg
