Again, thanks for the encouragement guys. I'm amazed at what one can learn reading back on the various build threads here. Man, you guys know your stuff!
Did a bit more wrestling with the slides (?) and needles today, one stubborn one left. Will try soaking a bit more break free, and maybe applying some gentle heat. Hoping to have the rack soaking in pine sol by the weekend while I polish up the bowls and top caps.
