Sine bar errors

[Paul Jones]

Marv,

I totally agree with your analysis. I realized I didn't need the super precise sine bar for my work and could either make my own like you did or buy a used one on eBay. I bought a "previously owned" 5" sine bar on eBay because used sine bars seem to be highly discounted despite being of the highly precise variety and no obvious signs of wear or corrosion.

I like your approach of building your own sine bar for general use around the shop but I took the easy way out. However, for a lot of my small part machining, I could also used a 2.5" sine bar which would be a fun project.

Thank you,

Paul

Post Script - I put the sine bar project on hold because I bought a new, never used, 2.5" sine bar manufactured by Fischer Machine Products for $25.75 on eBay. I have bought other Fischer Machine Products and they are very precise and well made.
