Nice Job Captain , Can I give one little piece of advice , the rollers your are using for the slides are kv full extension rollers (from work I assume we use the same ones) They are not meant to be mounted in a horizontal fashion( found out the hard way of course) , It may work now put in time all the ball bearings will fall out (possibly into the tank) when this happens the rollers will no longer support the weight of the pull out shelf and will come crashing down, you could use the same rollers you just have to re-design the shelf to use vertical rollers.
