4.0 out of 5 stars Just for pros, June 12, 2001

By	Jonathan Conway "stairgod" (Schuylkill Haven, Pa United States) - See all my reviews (REAL NAME)

These trammels are the next best thing to the old Stanley #94 trammels that are rare these days. The offset cams for "precision adjustments" are a pain to use because you have to back off the nut pretty far and the overcome the spring pressure to move them, but considering these trammels are best used for scribing big arcs and radii, as in layout work for circular stairs and millwork, in isn't that big a deal. Bottom line is if you need to do precision division work, get General's trammels with the side adjustment nut, but if you need big and beefy, these are the ones.

this trammel is well made and can be mounted on a 2x4 for larger circles if needed.only drawback it needs is a fine adjusting screw for fine tunning a measurement.

A great instrument for measuring when other ways are more troublesome. Worth the price when you really need it.
