    Come on, out with it! For a couple of years I have been casually planning to build a utility vehicle for the farm. Something like a John Deere gator but way cooler. 4x4, all wheel steering, etc.

    So what's up?
    I don't have any specific projects lined up yet, but having the ability to bend thin wall tubing is something I definitely wanted in my new shop.

    3 ph has it figured out..
    Like a bike collector told me, you can't have all the bikes at once, but if you keep getting rid of some you can have almost everything once..
    But 3 phase has it figured out, after a while when you get tired of some stuff you just give it away.. that way it AlWAYS goes..

    And then you got room for more stuff, and you just get more..

    The steel market is so crazy, prices and stock availability, these days not sure if DOM seamed tube is still available. It used to be quite a bit less in price than seamless DOM .

    It's quite a process to pierce a red hot billet to produce seamless DOM. I had a chance to tour a plant in Northern Cal that made hydraulic cylinder bodies that way.

    A local shop needed seamless titanium DOM around 8" ID. It was so hard to find they bought solid bars and had the supplier send the material out to have the ID trepanned out. The trepanning company did it free and kept the slug.

    Seamless "hot rolled/drawn?" "pressure rated" steam pipe is same price as welded around here(or even cheaper). Around 2.5eur/kg or 5usd/lbs. Usual wall thickness for 1.9" OD is 0.11"
    Cold drawn seamless is easiest to find sold as hydraulic tube , price is about 2x hot rolled seamless. Cold drawn hydraulic tube is also approved for FIA safety chassis material.
    If US market is anything like here 3-PH lightbulb should also ask the prices for hydraulic tube.

    And remember that 2" pipe and 2" tube are not even nearly same size and need different dies.

    Well not to change the topic too much, but with all the online metal stores, which one offers the best value on shipping? I am trying to stock up on CR and 6061.

    Ebay, beats them all. Various metals I bought recently were under half the price of the online metal suppliers.

    A example, 4inch round 3 in long C360 brass, $68 a inch from online supplier plus shipping, ebay $60 with free shipping.
    3/4 dia TGP 4140 prehard rounds, 10 in long, $2 ea on ebay with free ship,

    Make sure you bring some with you when you come. Besides organizing and cleaning up my shop we can build my UTV while you are here.
