Vee Block Adjustment Jack

[Toolmaker51]

While sine bars are far more widely used, fussing with Jo blocks gets tedious. Per inserted text, this provides adjustment while indicating for inspection or grinding. Commercial blocks vary in design, so shape of attachment may not be your solution. The idea here promotes the mechanical aspect, and nearly universal.



One more tip. When Jo blocks and sine bar are called for, I slip feeler gages under the base roll for small incremental changes.
