The July 2002 workshop at the Obadiah La Tourette Mill brought participants together from New Jersey, New York and Colorado. Work was successfully undertaken in two areas - repointing stone and constructing mortise and tenon joists.

Instruction was given on the properties of historic mortar and the best materials for use in the turbine bay area that is at times underwater. This was followed by instruction in fabricating tenons on floor joists and mortises in beams, using tools from the original era of construction. By the end of the week four new floor joists were in place and a considerable amount of repointing was completed. Fieldtrips to historic local lime kilns and a nearby restored mill gave added insight into the work completed during the workshop.

The mill, built in 1751, is located on the South Branch of the Raritan River, in northwestern New Jersey. It originally ground grist into flour, powered by two water wheels. The mill was renovated and converted to turbine power in the 1870's by then-owner Obadiah La Tourette, and the milling operation continued until WW II. Unoccupied since 1967, the mill and eleven acres of river front property were purchased in 1991 by the Washington Township Land Trust. At that time the oldest section of the mill was in a state of collapse and had been condemned. The Land Trust is currently restoring the mill with the help of volunteers, grants and donated funds.
