Guys, if you're married, and you surprise your wife with one of these, you and the table will probably both end up in the garage indefinitely. If your wife likes it, she's a keeper, make sure you hold on to her. Women, if you're thinking about making one of these, I'm single. (wink, wink)
Step 1: What you'll need
- Drill and drill bits
- Hacksaw or other metal cutting tool
2 - wheels with or without tires
4 - 5/16" x 24" allthread (if your wheels have 5 or more lugs you will need 5 or more pieces. You might get by with 3 but that will leave empty holes where there should be a nut)
4 - 2" swivel casters
4 - 5/16" acorn nuts
4 - 5/16" rubber washers (I'd probably skip these if I had to do it again)
4 - 5/16" steel washers
4 - 5/16" T-nuts
Can of flat black spray paint
Round glass - 28" by 1/4" thick
I was going to use allthread that was the right size to screw my lug nuts onto instead of using the acorn nuts but my lug nuts are 12mm with 1.5 threads and I couldn't find alltread that size at a reasonable price so I ended up using 5/16" with acorn nuts instead.
Step 2: Making the base
Paint the base flat black (pictures didn't turn out) so you don't see it when you look down through the wheel and let it dry overnight. I painted the top and the sides but left the bottom unpainted for several reasons. I was running out of paint because I didn't start with a full can, also it would make it hard to see marks you'll be making to align holes for the allthread and the casters. When was the last time you saw a piece of furniture that was painted on the bottom anyways?
Step 3: Clean your wheels
Step 4: Base Assembly
Make two lines at a 90 degree angle to each other on the bottom of the base that intersect at the screw hole in the center. Measure how far apart the lug nut holes are on your wheels and mark that same spacing on the lines you just drew. Then drill a hole at each mark. The hole needs to be appropriately sized to fit the center part of the t-nut. After drilling, insert a t-nut in each hole and hammer it in until it sits flat on the base. The spurs go into the base and keep the nut from spinning when you screw the allthread in. Attach a caster on each line near the outer edge of the base. Exact placement isn't that important as long as it's close.
You could do without casters but keep in mind that the table won't be light (mine weighs in around 70 pounds without the glass) and depending on the wheels and tires you use, the rubber may be on the floor instead of the plywood base and it will not slide. If the base is going to be on the floor, you will probably want to countersink the t-nuts so they don't scratch your floor.
Step 5: Continue Assembly
Step 6: Final assembly
Since my wheels had 8 holes to fit different lug nut spacing and I only used 4 acorn nuts I set my lug nuts in the other 4 holes. They're not fixed in place but the holes and the nuts are tapered so they sit there nicely.
Step 7: Final Thoughts
- I got the allthread, nuts, and washers at Lowes for just over $15.
- The casters are from Harbor Freight and came to about $12.
- I got the glass at a local "Mom and Pop" glass place for $40.
- I already had the paint but I think it was about $5.
- I liberated the plywood from the dumpster at work so there was no cost there and I haven't bought any lately so I have no idea how much that would be.
Total for the whole thing came in around $725. That's way more than I would usually pay for a table but since the expensive parts were just taking up space in my garage and I needed a table for my monitor, I figured why not.
The height of your table will vary depending on the size of your wheels and tires. My wheels are 17x7 and the tires are 205/40/ZR17. Overall height including casters and glass is almost exactly 19".
One day I might make another table with the other 2 wheels or possibly get an oval shaped piece of glass to put over both of them and use it as a coffee table.
