Bill,
Those were great plans for the rollout cabinet drawers! I had done the same thing with our kitchen cabinets a while ago - for the same reasons - bad backs and knees!
We've gone the "plastic basket route" for the TM, and it has been a huge improvement, but I like the rollout drawers and may re-think the issue. Quick question: the slides you used, were they the "full extension" type or partial extension, or does it matter? I know those full extension slides are nice, but a little pricey. I agree with using the white spruce wood if you can find it - light and relatively strong for this purpose.
