    Homemade wooden pull up bar station question about base size

    I'm not allowed to use a doorway, ceiling or wall mounted pullup bar.

    So if I make one from wood and bolts roughly like pictured here
    http://maxweights.blogspot.ca/2012/0...bar-hello.html

    I was thinking I'd use 4x4 on the base, and 2 2x4s for each side of the uprights, and some 2x4 for the bracing on each side and to hold both half's in place (instead of the pipes he has on the bottom)

    I probably can't do 1 full chin up, so it only has to support me a ~218lb

    My question is

    Is 4' of 4x4 on each side enough at the base, and where would I position the uprights, in the middle at the 2' point or could I center them on the 3' point....so that it could fit in a corner better


    Size wise could I even get by with 3' total base length

    ....I guess it could double as a clothes hanger rack in my bachelor pad

    Do you plan to swing at all on it or do kipping pull ups?

    If not, I think you can get by with a fairly shallow base though, obviously, the wider it is, the more stable it will be.

    I would position the uprights at the center of the horizontal members forming the base. You will need (diagonal) bracing as shown in that link you provided.

    You will find that stability will be enhanced, especially on carpet, if you place one foot (for four total) at each corner of the base. The foot can be something as simple as short piece of 2x4 nailed or screwed to the bottom at each corner of the brace. If you don't put these feet in, it'll probably wobble, even without weight on it.

    No I just want to start doing standard chinups and pullups...But since I will bolt it together I can easily add a larger base down the road if needed.

    The room has really short carpet so that's perfect. So if I used a 30" 4x4 for each base, with the uprights sitting on top in the middle that's about 15" on all four sides, that should be steady enough then. I do have some big plates like 2x50lb, 2x35lb I could always use to help steady it.

    ....if it wasn't I'd just go by another $8 8' 4x4

    Not sure. 30" doesn't seem wide enough to me. I haven't done any calculations to support this; it's just a gut feeling.

    I agree. Maybe for chins, but not pullups.

    Sounds like you need a set of stall bars, err, I mean an indoor clothes hanger.

    Well I'll be getting an 8' 4x4 and cutting it in half. If I could keep the base 3' or under it would really be out of my way. Safety 1st, but.....I can lay about 220lbs in 6 plates on it

    First off I would se 4x4 for the uprights and build the base out of 2x4 not the other way around. Otherwise just like that link would work just fine.
