    Default DOM tubing and types

    With a tubing bender, I'm finally going to switch over from building silly things out of SCH-40 pipe to silly things out of DOM tube.

    I'm going to stock up on DOM and was wondering what the most popular sizes are for items like go-kart frames, mini-bike frames, up to full road/race worthy tube frame structures.

    I know going from thick-wall pipe to thin(ner) wall DOM requires additional thought/engineering/triangulation but I'm wondering what are the typical OD and wall thicknesses used.

    It appears like 3/4" OD .065" wall, 1" OD .095" wall, 1.25" OD .095" wall, and 1.5" OD .120" wall might cover general frame material, and maybe some heavier 1.25" OD .250" wall for building suspension components like A-arms, 5-links, swing-arms, etc.

    What do you guys think?

    One of the more common cage sizes is 1.625. For my stuff I have the 1.625, 1.75, 1.25 and 1" dies.

    The most common size for go cart frames, atv's etc. is around 1" .090 wall. All depends on what your needs are.
    When it comes time for a project you'll never have the right size on hand and you can't stock every size and wall thickness made.

    Don't forget a few feet each of sizes like 3/4 x.188 1"x.188 1"x.250 and 1-1/4x.250 it comes in handy for making bushings and spacers.
    I just need one more tool,just one!

    Thanks, I plan on buying plenty of different sizes in low quantity like you suggest. I'm planning on getting ~120' of each of the frame sizes though so I'm trying to figure out what the best sizes are to get in bulk.

    Check with the rule books for various race organizations like SCORE or NASCAR.
    They will spec out the OD and wall for Roll cages. That will be the biggest size you need.

    I have built several single seat desert off road cars.

    1.5x .095, 1.5x .083 with 1x.83 diagonals for the larger cars.

    1.25x .095, 1.25x .063 with 1 and 3/4 x 0.065 diagonals for smaller cars.

    I am thinking you will always have to order in and it will be a long time before you would get bulk pricing.
    That would be how many Tons are you buying, not how many feet.
    There are a lot of variables, in sizes.
    Best bet stock what you know (or think ) you will use, and then order in as needed.

    How many die sizes will you have ?

    Steel prices are high. Not a great time to stock up. I would be on an 'as needed basis' for a while.

    I made my cages out of 1.75" diameter and .120 wall thickness for jeeps and broncos.

    Are you sure you want to be a Harbor Freight Warehouse, AND a Tubing Supply Warehouse ?
