“Hey man, weight is weight. I'm not lifting gold bricks here.”
Milled Dumbbell Bar with Black Oxide Comparison Shot with Old Non-Milled Standard Size Dumbbell Bar
Variations on that theme are as common as love gone bad in a honky-tonk bar band. When it comes to fitness equipment it may even be an intelligent statement. For example, plate loaded leg presses don't need highly accurate weight. On the other hand, good dumbbell bars do make a difference.
This Atomic Athletic Bomb Proof Bulletin is the first in a series on the ins and outs of the garage gym dumbbell. I'm starting off with your dumbbell bars, because they can really be the foundation for a fully functioning garage gym.
I believe that every gym needs some standard sized equipment. For the Doubting Thomas out there, who only believes in Olympic equipment, I would like to point out Pro-Style Dumbbells. That type of dumbbell uses standard sized plates, which simply means that the hole in the plates is designed for a one (1”) inch diameter bar. For the lifter who will not use standard sized plates, I will send you directly to the plate loaded Olympic Dumbbell Handle... go ahead, click that link... Now the rest of us can move on.
The photo above shows an old, typical, standard size dumbbell bar (left side) in my collection. I have no idea of the age, but it has had a lot of use over the years. I believe I bought it from York Barbell twenty years ago. To the casual observer, it looks round, but it is not. In fact, it was never round. Unless your bars have been milled or turned round, like the one on the right, then that bar stock has flats and dings all over the place. That leads to the low tolerances that are required for most fitness equipment. For example, our Allen Collars are made of a high grade springy steel with a center hole that is drilled out to a one inch diameter. Some lifters will pry them open and force them onto a worn, low grade bar, because they never intend to remove them. But if you look closely at the photo, you will see a spot where someone really cranked down with a wrenchless screw collar and buggered the steel. Unless I took a file to that spot, there is no way an Allen Collar would slide over it. I would be stuck using a set screw collar or wrenchless screw collar, whether I liked it or not.
Building Rotating Thick Handle Dumbbells
If you have never used a rotating handle dumbbell, then you are in for a treat. Sure, you might think that you don't do cleans with your dumbbells, but I would ask how you get them to your shoulders for pressing. A rotating handle dumbbell is great, even for a basic dumbbell curl. It is easy to make your own, with parts you may already have. Using our Brass Thick Handle Adapter, a standard dumbbell bar, plates and collars, you can build your own.
The question you have to ask yourself is, “How well do I want these dumbbells to rotate?” If you want them smooth and fast, then you simply can't use the old dumbbell bar (Photo-Left). In fact, you probably want to use a pair of Allen Collars on either side of the handle with a millimeter of clearance. Then butt your plates up to the Allen Collars and secure them with another collar on the outside. If you used good milled bars, then the handle should rotate nicely. We have those bars in both fifteen inch (15”) and twenty inch (20”) lengths. The eight inch length bars we sell are for the Iron Boots.
All the best,
"Today is a good day to lift."
