need an odd size alumium tubing - anyone know of online stores ?

i have a lathe to adjust the final ID and OD of the pieces i have to make, i just need stock to start with that gives me enough material to work with

final required sizes
first piece: 1.69" ID & 1.9 OD
second piece: 1.75 ID & 1.9 OD

typicly available tubing can be found in 1.75 ID X 2.0 OD , but i wonder about accuracy, as i would much rather have sligthly LESS then 1.75ID and have to open it up, then have 1.75+ and have to much slack in the part

and since this is a protype part, if i had the pieces machined im looking at 300+ for the parts, just to make stuff i already have the lathe for

it depends on the legnth your looking for

call up Metal Supermarkets in Buffalo (elmwood and military) or Rober James Sales on Walden ave. Those are the only 2 places locally i can think of that you can purchase tubing/pipe without having to purchase a full lenght of stock.

How long?
I might be able to help with the second piece but the first piece would be a pretty heavy wall which I don’t carry.

We use both when we’re in a bind.
