I am planning to build new drawers for some stick-built kitchen cabinets. I would like to use full extension, soft close, undermount slides, but havin g no experience with drawer slides, I don't know if it's practical.
The following link shows the view through one of the drawer openings. As yo u can see, there is currently a 1" wide runner that the edges of the existi ng drawers simply ride on. The picture shows the right hand runner for the drawer that was removed and the left hand runner for the next drawer over, which is pulled out about 1/2 way. (The yellow vinyl tape on was an attempt to make the runner a little more slippery.)
I should note that 2 of the 5 drawers have runners that are only ~3/4" - 11 /16" wide, not the full 1" shown in the picture.
The cabinets are ~24" deep, from the back of the face frame to the back wal l. The back wall of the cabinets is actually the plaster wall of the house, although there is a cleat that the runners are attached to.
I would like the drawers to be as deep as possible. I've seen some 22" slid es, which means the drawer boxes have to be 22" long, right?
The drawers will be made from either 1/2" Baltic Birch plywood or 1/2" popl ar. (opinions welcome, as I'm new at this)
Are there undermount drawer slides that will sit on the existing runners or do the runners have to be removed or can they be left in place and the sli des installed some other way?
If undermounts are impractical in this situation, what are my other choices ?
Thanks for your (gentle) guidance.
