Meet the Franken-Inch Dumbbell

Recommended Posts

crazy_bee

Hey guys,

 

I had this idea for an homemade inch Dumbbell. I really wanted to buy a cast replica but it would have costed me about 800 CAD.

Being a father of three young kids that kind of expense is hard to fit in the budget.

That is how i thought of doing my own. Yes, I know, the FBBC handle is still the cheapest way to go. But I wanted to have a real, one solid piece dumbbell.

I found out that if you take two 88 pounds Kettlebells, cut the handles and weld a 2.5 inch CRS handle to them, you have a very realistic replica.

I will have to weight it further with a proper scale, but i got a little over 170lbs on my bathroom scale with it.

 

 

You can do the same thing with 32kg bells for a smaller replica. For smaller than that you might want to do this with competition kettlebells, it would do a better more rotational force with the larger globes.

Be sure to do this with cast steel kettlebells and not cast iron. ( Cast iron is a pain in the ass to weld.) You will need close to 300 amps welder to weld that thick, so you might want to take it to a welding shop.

 

I hope it helps someone, and most importantly that this wasn't talked about before.

 

Thanks,

 

David Hoffman

Wow!  Practical and (relatively) inexpensive. Great job!

Do you think the welds will hold ok? 

Globe dumbbells cop a lot of dropping (based on my experience) :blush

Great idea! Any cheap sources for the kettlebells @crazy_bee? What brand did you use?

I think if one knows the proper techniques for welding cast iron, this is a great idea.  Having said that, given the size of the cast iron, it should be fairly forgiving.

That looks great, dude. Is that SMAW? I am also curious about what brand of kettlebell you used.

2- 90lb kettlebells equal future goals 😁 I still need to cut the handles off and paint.

I'd leave the handles on. Might make it easier to transport...

Makes it heavier too. I'm not sure of it'll kill rotation though.

Shouldn't affect rotation. How are the handles attached?

also, if your not able to lift it, you can now hook tubing to those handles and attach it to a pull up bar so give a little help until you can lift it solo

I think he started with 1" handle and just did a 3,000 pass weld.

No welding on this bad boy. Loctite. I also had the handle drilled and tapped 1"-8 so I could use all thread to put it together. Feels pretty rigid. @Squeezus
