90 degree bender for 1/8" bar

I've just spent the past 1/2 hour on the internet trying to figure out if there is a tool that will bend 1/8" stainless steel bar at a 90 degree angle. I know there are a lot of compact benders out there, but I don't know if the throat is tall enough to accommodate 8"L x 1-1/2" W x 1/8" bar. Does anyone on the list have a bender that can bend bar at a sharp 90 degree angle?

I usually heat the stainless in my vise with my rosebud torch and hit it with a sledge hammer until it bends to a 90 degree angle. There has to be a quicker, better way. I will need to make 140+ of these for a fireplace installation. I'm trying to create an estimate for all of our installation labor and I'd like to cut down on my fabrication labor time.

Help!

Bending bar

If you are trying to bend 1/8 X 1-1/2 flat the long way, (along the 8" direction) you may be in for a bunch of failures. Instead you should contact a local sheet metal contractor and have him cut you some strips of sheet. The failure rate of bending flat bar the long way is quite high because of the grain produced by rolling it into a long bar in the first place. When you bend along the grain, it tends to split. If however you get sheet cut against the grain, it will bend very nicely. You probably knew this, but a word to the wise is not usually wasted.

Bending

Em,
It's late as I'm not quite sure of how you want this bend, but if you are bending the 8" into 4" per side I think it can be done. Again I'm not sure with stainless because I've never put it into my bender , yet! But I have a Hossfield bender with a bending dog which will bend steel on a ninety degree angle without heat. Find someone in your area who has a hossfield bender and ask. Janet R.
P.S. I like a woman with a hammer!

Re:Bending

Dear Janet,
Thanks for confirming that. I'll make a trip in to Cleveland and ask a blacksmith I know there. If I could see it done on someone's bender I'd feel better about buying a new tool. Not that I wouldn't just love to have the tool anyway...

Bending bar

Thanks Rick, but I happily will be bending the clamps in half in the other direction. So 4" before and after the bend.

V fullers or press maybe?

Would you be able to use a jig in a press, possibly even an arbor press to bang out the series? (or fullering under a power hammer)
Not sure how identical you need the 140 to be, but it sounds like enough to use a forge, so you can get a lineup of pieces hot more economically that just oxy/acet, maybe even just a pre-heat before torching...
the iforgeiron.com blueprints may help you!

Bending Stainless

Bending 1/8 stainless is no big deal. Go to a sheet metal shop and have them shear and bend the parts you need out of a flat sheet. The shear can be set to bang out the 140 parts quickly and a power brake will give you good repeatable results. If you need holes, they can punch them too. The holes will be more round than drilling. Sometimes it does not pay to do it yourself, especially if you don't have the equipment already.

Re: V fullers or press maybe?

Dear Ben,
Thanks for the link. I'll try to register later when the site maintenance is done. Sadly, I do not have a working forge, power hammer or press. Today I have received some excellent advice about machines that I will have to purchase at some point in the future. An ironworked scares me to death, but would simplify the clamp making process. The Hossfeld bender has almost legendary status, now due to its affordability and prowess. The world may just stop spinning if I get a press and the necessary tooling.
