1-1/4 X 1-1/4 solid bar stock

Dean Olson · Mar 8, 2011

Anybody know where to find some? I need 2-36" pieces.

Local steel suppliers say it's an odd size.

I'm have a Farmall C-254 cultivator for my Super C that I want to make another attachment specifically to mount deep fertilizer injector knives.

I usually buy from discount steel, but they are close by. Minimally they have a great website to look for prices and availability.

I'm assuming you don't need hardened steel.

Make what you need.Lay a piece of 1/4"flat bar to two sides of a 1x1"Square

Great tip. Thank you.

This will be used to support a single fertilizer knife running about
4" deep in front of a planter . It will be in freshly tilled soil. I
suspect that standard steel will be more than strong enough.

Look here: McMaster-Carr

Doesn't seem that odd

Where are you located?

1 1/4 sq is not an odd size and honestly 1 1/4 square tubing with a 3/16 wall will probably be plenty heavy.

Any commercial steel supplier will be able to get you that material without issue. Buy an entire length of tube vs having it cut... Saw cutting is generally more expensive than if you bought an entire 20 or 24 footer...

You'll have 1 1/2" then.

gene bender · Mar 9, 2011

Where do you live. You can get sq tube with thick wall also.

DeltaRed · Mar 9, 2011

Not oppisite sides...adjoining sides.2 oppisite sides will be 1x1 1/2....2 adjoining sides will be 1 1/4x1 1/4.

You could always sleeve it with another smaller piece increase it's strength. Can't get the cheap welded seam and do it.

Richmond TX. Just outside Houston. The 2 steel wholesalers, major facilities, I normally deal with don't stock it. I'll make a few more phone calls. Surely in a town this size its in stock somewhere.

I've learned not to tell any suppliers what I'm working on because the automatic response is "we don't carry that".

A 1 1/4 sq tube with a 3/16 wall thickness is about 66% as stiff as a solid 1 1/4" bar - Assuming both are similar materials with similar strength properties and modulus of elasticity.

As an example, a 48" long piece of say 1 1/4 sq solid A36 , fixed at one end with a 1000 lb distributed load deflects 2.22 inches at the end. A mild steel 1 1/4 sq x .19 wall tube deflects 3.31 inches under the same constraint and loading.

If i can get it here in IOWA you sure should be able to get it in TEXAS but if worse comes to worse if have some let me know.

So how strong is it if you sleeve them?
