    That would probably be a nice price on them, especially if they had removable pieces, so you can change the bend radius. By the time you made a few, you could easily reduce speed to half what it originally took to make one. Running a batch of 10 would lower it a lot.

    I really don't have time to do it. At work, I'm way too busy, and don't work in the shop anymore. At home, I'm busy with family and other hobbies.

    This thread is back. I may need to get a rotary type of bender for another application, and may be able to kill two birds with one stone. Any of you know of some good places to check into these?

    Yeah I just knew I had a fork stuck in me. The other guys were regulars with the company. I remember over hearing a radio conversation (no cell phones in those days) with this foreman and one of the owners of the company. The foreman wanted all our checks for failing the test. I heard the owner say “JR, these are the best weldors we can find, think about it…. If everyone failed there must be another reason, anyway if anybody goes down the road it will be you!”

    I have heard this also. I know I’ve taken pipe test where they would UT or shoot them before bending. Their theory was it’s a lot less labor to shoot or UT, then cut prep, bend and have a guy fail.

    Years ago I did an open root pipe test at the San Francisco airport, soon as I was done they UT’ed it, perfect, couldn’t find anything , took the pipe in to prep it for bending and tensile. Next day they came back and ask me right in front of the whole crew, “ What the **** did you do to that pipe”? I guess the coupons shattered like glass . So I look around for the foreman to see if he has my check. He puts me to beveling pipe while the other guys finish their test. Couple days later same thing everybody fails the bend, but passed the UT. Ran some test on the pipe; results came back the used pipe the company had bought from Colorado Coal and Steam was not weld able . Man was that a relief to me I needed that job!

    That really depends on how well you can weld. I'd rather xray because I don't have to cut out and prepare the bend specimens.

    all I know is if it isn't welded a 100% with the bend test then it is going to break lol

I don't know if this thing was home made or not but is nice. by the way thanks for help with my 2G pipe it came out great today. Thanks

    Chris
    Glad your test came out well!!

    I think we may just go with xray testing. If we consider the cost of having guys cut and prep bend coupons, in addition to the lost production, the cost will probably come out to equal to what it costs to get an xray done...and we will get a discount if we do several xrays at once. Not only that, but we can easily store the xrays for recordkeeping.

    I really didn't think that xray would be the cost-effective option. However, I needed to show all options before I went for approval to buy something. Good thing I did, cause this will be a lot easier, and more effective.

    Those are some nice benders, but still not in the range where I can go to the boss and tell him that, based on price to buy/work to make, we should buy one. I may just wind up making one.
