Glue was applied to each layer, and clamps applied at close intervals along the length of the beam. In the photo on the left, John is applying glue, while Tom, Craig, and George are supplying moral support. On the right, above, John is tightening one of many clamps used.
On the next day, Friday, another piece was glued on to one side of the beam to span the edges of the pieces that were glued together previously. The photo on the left, above, shows this with the clamps in place. Note the thinner piece in the center that was used to achieve a dimension close to what is needed. This was obtained by cutting a 2" piece on the bandsaw.
On Saturday, after clamp removal, the beam was run through the planer several times to get it down to the proper dimensions, and taken several blocks to the work site as shown on the right, above. It even looks quite straight. The sill that will be replaced is the lower one adjacent to the new beam. The vertical and horizontal framing members are mortised into the existing sill, so more work will need to be done on the new one before it is ready.
