under the cabinet ducktwork
I'm in the process of redoing kitchen- one of my HVAC forced air/heat register is behind where one of my base cabinets will go (we are going to try and relocate it)- If not - where do I purchase (or have made) some type or ductwork that attaches to the existing register (I think it's like 6" x 8")- to a small, narrow duct to run out the toe kick? My other option was to buy one of those electric toe kick heaters but then I have no solution for the AC in the summer?? thoughts?

If you are a little bit handy, with some metal sheet you can build a closed or a U shaped (make is easier to screw to the floor) duct and attach it to the register, I did it once. Is not pretty, but once the cabinet are on, is not visible.

Simpler to just make it out of plywood.

I probably did not do it the right way but I ended up using a flexible duct, routed in the 4" tall empty cavity under the cabinet.

Building code requires that the entire warm part of a heating system be enclosed in metal sheet, even when is probably safe to use some plywood at the very end of the system.

That is not good, the nylon pipe is going to slow the flow of the air, and it looks terrible. Use rigid metal pipe, or even better, use a metal box, I installed hundred of those (I hated to do it, because I installed them when the cabinet where already on place, it's a very unpleasant job to access that small space, so low on the floor), google for "toe kick vent".

Nylon duct is only 30" long, fully extended, so I am going to guess minimal amount of air flow resistance.

With the duct work being offset in relation to toe kick vent, I just could not get the hard ducts to work without multiple turns, possibly creating leaks.

Here is the finished picture:

From the outside that looks really good. About the duct work, now it's done, but you can use rigid metal elbows, that you can adjust the angle from 0 to 90 degrees and put 2 or 3 in your case.

OP, You may want to look into this kit ( I don't think it is much different than what I have done, but it does provide you with some adapters.
