It seems to me that this ought to call for active discussion. E. K. Barrett: --The report mentions the jacking up of stringers by bolting on side braces. I get away from that by using a 2-in.x2-in. extension clamp which leaves it 12 in. in the clear, and the horns drop down and catch under the outside stringer. The saddle catches over the foot lift of the jack, so I don't have to bolt on any sash braces. I simply roll the jack into place and it will pick the stringers up without bolting on side braces. G. W. Rear: --My understanding of this idea in trying to get the cap out was to jack up the weight so as to get it off the cap. The only objection I have is to the driving of piles under a trestle without the stringers having been shifted so that the piles are driven in their proper place. I don't believe that a good job can be done by trying to drive the piles unless the stringers have been shifted so as to get the pile started where it is intended to be, and driving it where it is intended to stay--either with a 3ply or a 4-ply chord. We have never yet been able to find a way of doing a good job without shifting the stringers, especially on the lower trestles. It may be that when the trestle is of considerable height that the piles can be spotted in without springing them too much out of the way. We find in our practice that the best way is to go to the bridge with a pile driver and finish up the job before you leave it.
