Sold my 40lb DBs and 100lb barbell (concrete+plastic) for $250

Bought some aluminum sheeting, a metal pipe, and concrete.

Going to make my own set of adjustable dumbbells by using 5lb concrete casted plates.

The iron pipe is capped off at both ends.
To change weight, unscrew one side, add weight and swap with appropriate pvc handle/spacer.

The hardest part is making the mold and figuring out dimensions for plate.

Pipe is like $15.
Pvc ~$3.
Concrete $5 for 80lbs.

Once I have prototype mold and technique/process down will make molds for mass production.

When I listed my weights, i had 12 responses same day asking to buy them.

Will sell these 40lb adjustable DBs for $40-60 or so depending on demand.

Shipping costs prohibits selling outside city (lose cost advantage) .
Will make extra molds and equipment needed to make your own and sell to people in different cities.

This is literally a money printing machine right now.

This OP. Nobody wants them. They take like 3 days to make and they lowball you on the price because "hey, it's just concrete, I could do that!"
t. made my own and tried to market them

PS: use quickcrete tube molds and hot glue.

hey retards how about coating it in rubber so you don't have to tell them it's concrete, just a "custom plate"
if you can't convince people into buying shit, trick them.
>Once I have prototype mold and technique/process down will make molds for mass production.
what would you use? wouldn't silicon molds deform because of the weight?
I don't know much about concrete and manly shit, but I do know how to make silicon molds n shit.
If you design it well enough, you can sell half the price of any gouged price, thus getting more business.
I don't really know about the law and this shit, you'll have to report the income to the IRS, and if the shit breaks and injures a customer they could hold you liable.

If you just throw concrete in a bucket and call it a day.
Of course no one will buy it.

However, the key difference is that these are adjustable.

10-40lb which is right where a majority of people use for weight.

This eliminates the need to purchase incremental dumbbells or adjustable dumbbells that cost ~$300 right now.
Both of which are out of stock everywhere.

Key points:
-Adjustable
-Floating grip
-rubberized (going to coat them in flex seal or other rubber epoxy as a finish)
-cheap

>pvc handle

op is girly hand pussy

The pvc fits like a sleeve over the iron pipe.
It doubles as a spacer for the plates as well as handle.

It's like a built in thick grip. Much thicker than a standard dumbbell handle and more like an oly bar.

>pvc pipe bends
>weights fly off
>floor ruined, foot crushed
