    I built this jig out of 8020. Cost about 300$. The rear axle locator seems like crap, but i haven't had to file any of my dropouts. I used modified headset parts to locate the HT.

    It takes me quite a while to set the jig up, working from the rear axle and measuring everything forward, but it has produced good results. I miter/tack in the jig and braze in my work stand. If something has moved it's been easy to see. Each part gets removed/installed in the jig like 8 times, hah.

    I've also built a couple frames using a surface plate and fixture set. Similarly cost effective, but much more laborious. Maybe it's better for lugged building? I don't know. Only thing i prefer about it is how i'm not relying on the straightness of extruded aluminum and my own fabrication skill. Both methods produce frames of quality limited only by my metalworking skill.

    If i was going to build more than 2-3 frames per year i would buy a professional jig, but this arrangement works nicely for a hobbyist still figuring out each frame individually.

    fixture set. ......

    Rough estimate in total labor hrs it took you to build the jig?
    I realize times will vary depending on skill levels of each builder, just looking for a ballpark number.

    thanks, Brian

    Maybe it's different for someone who comes in to this with a mess of metal working skills and frame design/building skill, but 2 hours or 12 hours to build a jig is fairly meaningless. Those hours will be regained in time spent using the tool, and your first... ?dozen? ...frames will be so time consuming it doesn't really matter how much time you spend developing your tools if it means you get a better result.

    Time is free, if it's spent on a passion. The materials cost of that picture frame jig is low. If you're going in to business it's the wrong choice.

    That's my Instructable, and yes, the rear axle is the weakest part of the design. But it does get you going. I switched to an arm that takes a Anvil dummy axle.

    I got a new jig and have been meaning to list my Bringheli for awhile. New is $1500. I have a few additional accessories including 110, 120, 130, 135mm dummy axles, 44mm headtube cones and the post to mounts the jig in a Park stand. Was thinking $1200. It's in Colorado. Let me know if you're interested.

    PM sent.

    Iíve built a fat bike with the jig. Thereís plenty of clearance for it. I used some longer bolts for the dropouts and a bunch of washers to increase the spacing to 190. You could also probably get a long axle from Bringheli. Itís also easy to use a thru axle on the bike but build with 10mm QR dropouts if you use rockers/sliders or some other replaceable dropout.

    Building a jig for your first few frames is part of the fun and can be instructive... a rite of passage maybe?
    Plus it helps to bring understanding and appreciation for spending a lot of money on a nice jig.

    I may be selling my Bringheli jig soon, but I've got a couple more frames to finish on it (maybe ready to sell in May?). I've done a few mods for it, including making a dummy axle adapter that fits Anvil dummy axles. It'll build pretty much any hardtail.

    They go for $1,500 new and I'd probably want to get as close to $1,000 for it as possible. Shipping cost is also not an inconsequential part of the purchase. I'm in Denver, BTW. Let me know if you have any interest.

    I totally didn't see your post before I posted. I'm not trying to barge in front, Feldybikes. My apologies.

    I got a good deal on an old (early nineties) Henry James Universal jig. I spent lots of time and money machining adapters and new fixtures to make it capable of building a modern frame. Now the jig will accept Anvil dummy axles and a tapered head tube but I spent $700 getting it there. Iím feeling like I may have been better served buying some v blocks and building off a flat surface and full sized drawing for building my first frame. Just something to watch out for when buying a used jig...
