Step 1: In the Beginning
Being OCD enough to seldom throw things away, I had a piece of Mahogany left over from when I turned a old side board into a Vanity for the Master Bathroom. It was about 24 inches by 60 and had a piece of trim to match on one long side and the two short ones. This being a very old piece of furniture so the moldings were screwed on not nailed or glued so the first step was to remove it and then stare at the pieces until I came up with an idea.
I realized I had more than enough to make a good sized top for a nightstand with enough left over for a drawer front or I had enough for two sides. I also knew I had several sheets of Oak 3/4 furniture grade plywood leftover from when I trimmed the detail work I did to the ceiling of the great room and dining room from 2x4's.
The choice was obvious so I then focused on how to maximize the piece of Mahogany and how to also possible reuse the moldings that match it.
Since this isn't really an instructable on cabinetry and this isn't a one sized fits all project I'll let the pictures do the talking on how I cut it.
I then glued clamped and screwed the top together and set it aside to dry bottom facing up.
To determine the height the rail I measured the height of the walker my wife uses. Since that will vary in range for whoever you build one of these for, most likely the patient used the walker for some time it has been adjusted to fit them to a height they prefer. I got a measurement then placed the grabrail I had chosen on a flat surface and measure how high it was, subtracted that amount and the thickness of the top from the walker height measurement and was left with how high the night stand needs to be to end up at the same height as the walker. I also measured the inside the molding dimensions to get the correct size to build a box for the base. I added 2 more inches of overhang to the front to be sure there was an unobstructed area of floor and no danger of stubbing her toe.
Step 2: The Basic Box
I cut some thin strips from the scrap of mahogany about 1/4 wide to trim over the cut edge of the plywood and cut a piece out to fit into the top and bottom of your now 3 sided box. This would be a good time to add shelves if desired or a drawer or two. I chose to make a single drawer and started by attaching a strip of wood ripped from a 2x4 that was about a half inch thick and glued it to the inside of the left side at the height I wanted to mount my drawer hardware. On the right side since I wanted room to wire switches and outlets and the intercom I made the spacer about 2 inches thick but as wide as the left side and glue it at teh same hieght as the one on the left so it would accept the drawer hardware on the right side and leave me plenty of room for the electrical boxes.
The intercom needs about 2 inches and I figured that ensured me it would fit and leave me a 3/4 inch safety margin.
The bottom of the box was glued and held in place with finishing nails because I had a long strip of the Mahogany that I routered one side of so I could run a band around the base and tie it in visually to the moldings around the top.
The drawer is simply another box made of such dimensions that it fits inside the spacers previously glued to hold the slide hardware. After it has been tested to fit you just drill two 1/4 inch holes spaced horizontally though the front of the drawer then after aligning the finished drawer face you just screw it on from inside the drawer. This let me leave a longer overhang on the right side so the drawer looked aligned when closed since the center of the drawer itself shifted left.
Step 3: Finish It
Once I had those holes drilled I marked space for a double gang box on the back, carried the whole thing back to the garage and used a jig saw to cuts all these hole and mount the bracket to hold the intercom speaker, sanded everything a bit, brushed on some walnut stain inside and out the put two coats of polyurethane on with a light run over with fine steel wool.
After it was well dried I wired in a double set of switches meant to fit in one gang, two outlets on the back for the double gang box and wired a plug and flexible line long enough to plug it in. This lets me plug in a desk lamp and a fan, 1 to an outlet and have 2 switches in easy reach to turn lights on or off or fans or a vaporizer etc, whatever item an invalid might wish to have some control of activating without having to call for someone to do it.
I then wired the intercom speakers so they stayed clear of the AC lines and left a pigtail out the back long enough to tie it into the system, and brought it back to the bedroom, lined it up with the tape on the floor and put two lag bolts 2 inches into the stud using the spacer I had made to keep it square to the wall. The table won't tip when someone tries to pull on the rail even if I test it myself by hanging off it with my 170 pounds.
Its surprising how far a solid handrail in the right location will go to making someone with difficulties walking feel secure.
I also made the optional cup holder which also makes for a good place to keep pens and pencils or phone books medications etc.
