I agree with Wizard69 but would add that it is possible get all sorts of problems because the specification is that there are weights - end of story.

What rubbish goes into the melt is of no matter- to them. However, what happens when that hard spot turns out to be a bit of carbide.
Does this institute another bit of postbag which reads- My cheap jack lathe ( or not) has stripped a set of gears or a bull wheel or even a saddle with torn out tee slots' What do the experts say? Perhaps it would be cruel to say ' Penny wise, pound foolish'

Think again, does anyone want in an expensive lathe to find that casting sand has got under the saddle and the beautiful handscraping now looks like a metal cattle grid which has been run over with a full size battle tank.

Unreal? Sadly, it is all too true in the cold world of reality.

My thoughts but I've been there

In this hobby we usually spend a lot of time making parts. With all the setups and sometimes even making holding jigs, we can have many hours into one part. The cost of our material usually winds up as pennies per hour per part. Is it good to save a few pennies and maybe wind up with a junk part, or worse breaking a nice insert- that may cost $10?

I have a pretty good stock room full of 'mystery metal' and it seems every time I try to use some of it I am not happy with the final surface finish.

We spend a lot of money to buy tools and machines, so my view is to buy quality material, its the cheapest part of this hobby.

Off topic, perhaps but interesting !

Have some nice stainless cutlery which goes into the dishwasher with tablets.

Comes out with little red blotches where ordinary steel ( I guess) has reacted with the salt in the tablets-

To use the words of the Prophet---RUST

Cheers

This price is similar to others I have found in the past.
Two pieces cost more than I paid for my 7x lathe.
This puts it WAY out of my ballpark.

If I could find it for $6 a kilo, I wouldn't be looking at barbell weights.
Am I missing something?

You best sharpen up Your Google Foo, Speedy Metals list that size as $23+ shipping and any other cost They can dream up. Not related or even hardly a customer as I can usually do better than their price, just an example.

If you are THAT good, why wouldn't you give me the link where you get a better price? There, the imoji helps.

I prefer to buy metals locally when I can. Dura-Bar is a big company. I figured I should be able to pick it up instead of needing to get it shipped. That is the one name I hear most often when it comes to cast iron. I just don't understand why it costs so much. It has been my experience that when there is that much of a price difference, there's a reason.

If I buy mail order without seeing what I buy, how do I know the composition is any better than the bar bell weights? I have purchased steel online and it isn't always what it is advertised to be. There was a good metal supply company in Tampa, but it closed 15 years ago. There was also a a surplus/recycling place, but the State built a new road and bought the property, so it closed, also. I haven't been able to find a new supply since.

I did find what was supposed to be a great surplus place in Jacksonville. I took a trip up there to see what it was like. They had a lot of aluminum and small pieces of brass, but no cast iron. They had one shed with a lot of steel. I asked them what type some of it was and the guy said "you know, steel they build stuff with." It didn't give me a lot of confidence.

I freely admit that I am not good telling which type of steel is which. I prefer buying it from a knowledgeable source and don't mind paying a little more for the knowledge. I know even less about cast iron.

I've just returned from Aldi stores in Little England and next weeks offer is
1 x 10Kg or
2 x 5KG or
4 x 2.5KG

each set being 12.99

But earlier I got a Meehanite marking out table( rusty and unsuitable for marking out) for 3 quid.

I've just got a Myford ML10 plus a 3 jaw and it was index drilled, a 4 jaw, a faceplate, a catchplate, hard, soft, rotating and rotating centres , plus assorted drill chucks. I got a Potts drill unit( which few have heard of), a Cleeve swing tool, a QCTP etc ( Yuk) an normal one, a vertical slide and vice plus steadies and heaps of tools and jigs. Of course, there is whole Imperial set of cogs.

Imaging the cleaning and possible damage from weights, I think a stifled yawn might be appropriate as it all cost a mere 500.

sssfox, some CI issues/names/suppliers were discussed in this thread FWIW
http://www.homemodelenginemachinist.com/showthread.php?t=25282

As I posted, my only experience was CI rod for a cylinder liner supplied by Speedy. It was nice stuff to turn on the lathe, but I don't have any other comparative reference to other CI. I'm envious of the options available within USA but between the shipping cost & vendors, it narrows the field pretty quick in my locale.

I cant speak to your Durabar quote, but when I called a distributer (here in Canada) the $/ft didn't sound too excessive, but the min order was a show stopper. They seem to be industrial focused, at least here.
