I tried to explain that there was a slight technique to handle this weight.
Just username confusion again. Thanks. The company said they'll do it in MATERIAL GRADE ALLOY STEEL 6850.

Just to reconfirm. Your previous content has been restored. Pasted as rich text. March 13. Louis Cyr was a French Canadian strongman with a career spanning the late 19th and early 20th centuries. Thanks.
Sorry but this is beyond my abilities - sounds like great project! You can post now and register later. Edit: that's based on 7,9kg/dm^3 for 18-8 stainless steel also known as V2A.
I made a mistake earlier the 0.284 was actually lb/in^3. Louis Cyr is often considered the strongest man of his time, boasting feats like a 4,000lb back lift, a single arm overhead press of 273lb, and more.
This is an event that entails athletes having 90-seconds to complete the heaviest Cyr Dumbbell press that they can within the set time frame (dumbbells range from 274 lbs – 330 lbs). Is there anything else you need or do I have everything? Yeah I imagine it wouldn't be cheap, screwing the second globe on could get a bit tricky too. I found a good company that will do a dumbbell out of a CNC lathe tooling and is a single piece (not a two globes then molded to a handle). What is the length of the globes or spheres?
Can't do this at work right now but can get you the info tonight if nobody else chimes in.
The Cyr Dumbbell Rogue Fitness modelled the new Dumbbell on plans of the original that is currently held in the Stark Center.
A globe dumbbell like the inch. The company said they'll do it in MATERIAL GRADE ALLOY STEEL 6850. I was thinking of making one with a handle threaded on both ends and screwing the globes on so I could upgrade to heavier globes if I ever got to the stage where I could lift the first one. Join the BarBend … Upload or insert images from URL. Join the BarBend … I could turn the handle myself and then get the globes made by a machine shop, At least that way my Mrs wouldn't see the full amount on the credit card statement all in one hit.I wouldn't be able to lift for a while either, so I might start by making pipe cast with lead in the center that I can load with plates or something similar to progress my way up to it.
this deviation is not so critical, by the way, could you specify steel density you took into account while was calculating in kg per m^3. That difference would only amount to like 20 grams of the final dumbbell, I agree these are very minor but if you're a machinist the measurements probably need to be precise. But I need one more dumbbell. The handles should be 51MM thick and 4.5 Inch long (yes 4.5 inches not 4). I really should change mine at this point haha.

But this will be made of a single steel. Brass - 125765.173g @ 8.490 g/mm^3 -125.75kg (rounded) This can vary quite a bit because brass can have a lot of different compositions and the mass can changes depending on the composition.
Need some help in making a dumbbell.
It's as exact as I can get without knowing the specific type of steel, there's thousands all with slightly different densities but I don't think the variance would end up being more than about 3/4 of a kilo at this size. I've always wanted to have a thick handle with interchangeable globes, even additional handle sizes too would be a crazy good training tool and a space saver, tho not much of a wallet saver. What you're trying to confirm is the diameter of the globes and the total length.

I modeled one with your dimensions (as 1 solid piece) using Onshape and I calculated the mass for a few different materials. Personal records Strongman.
So I need the calculation of the parts. That's it. Skip to content.

I mean was it taken into consideration as the handles won't be going in the globes? 117 KG. You cannot paste images directly.
Just to remind total length = 596.48 mm or 59.648 cm or 23.4835 inches.
Thanks a lot. The dumbbell is 274lbs or 124kgs and the event was a tie for first place in 2014 with four competitors each completing 4 reps in the alotted 60 seconds, Brian Shaw, Mike Burke, Zydrunas Savickas and Hafthor Bjornsson.
I'm not suggesting anything @climber said was inaccurate, mass calculations are largely based on the standards charts you use to calculate mass and different sources quote slightly different values.

Which is only logical. It can always be challenged, of course, and if anyone will, it might be the man who currently holds the Cyr dumbbell world record (149.7kg/330lb): Mateusz Kieliszkowski. x.

This would weigh 116.45kg, using 0.284g/cm^s for the density of steel.
Christopher, if it was Stainless Steel will the calculations be same?
Clear editor. I want to do a Cyr Dumbbell replica (almost). How good/bad is that? x.
I want the dumbbell in steel. Get Stronger in 3 minutes (or less) World records, results, training, nutrition, breaking news, and more. Will the specs be same if I decided I want to go Stainless? I was a machinist in what now seems like a past life. Need some help in making a dumbbell. By this deviation is not so critical, by the way, could you specify steel density you took into account while was calculating in kg per m^3.
Just about any steel used in manufacturing is far stronger than the needs of a dumbbell, the only different it changes is calculating the precise weight, but even if you use the average steel densities you would be off by less than a pound in either direction. If Chris doesn't want to, I'll calculate it with pen and paper for you.
I'm thinking of having a circus dumbbell made myself, not a beast like the Cyr dumbbell though that would be an ornament for me.
I want to do a Cyr Dumbbell replica (almost). Told me Diameter times 2 plus handle length. It's not exactly twice the diameter plus handle because the globe goes into the handle a little bit, so you need to subtract that distance from each side. Now this is a small difference, it only comes out to be about 10mm in total length, and maybe 200 grams of weight. Mateusz Kieliszkowski's 320lb Cyr Dumbbell set a new Rogue Record.

Others are helpful. Subscribe. His recorded feats, including lifting 500 pounds with one finger and backlifting 4,337 pounds, show Cyr to be, according to former International Federation of BodyBuilding & Fitness chairman Ben Weider, the strongest man ever to have lived.

Nothing cut and molded into another.
