Hi Willis,
I don't know why that wouldn't work far better than what we're using now. The
problem I see with making a horizontally laminated bushing out of Delignit is
the short grain run length. By the time the hole is drilled, there's not enough
grain length to securely hold the lamination cross banding together unless the
plate webbing holes are reamed out so big that they overlap. There just isn't
room on a lot of plates for 1/2" bushings. A smaller diameter bushing that has
good compression resistance and won't come apart would be welcome. Thanks for
the information.

Best regards,

Ron N
