    https://thebicycleacademy.org/collec...me-fixture-kit

    has any one used this jig?
    is it worth it?
    should I spend more on a frame jig?
    what other jigs should i look at that are affordable?

    I am wanting to set up fat bikes to freestyle bmx so hi bb and low bb.

    I am just getting my home based shop set up and looking for feedback.

    Jeepers, awful complex and expensive for a "low cost" jig.
    No, I haven't used it.

    However I did build one very similar using structural steel "drops", C-clamps, threaded rod, and some bike hardware. It didn't cost me $300 even with a little help from a local machine shop.

    If you are looking to build several frames for various customers, buy a jig like that. If you are only looking to make a few for yourself, just hack something cheap and easy to get'er done. You might only use it once. Sorry, I don't mean to preach, you asked for feedback.

    I'd hate to get the shipping quote for shipping that sucker from the UK.

    ...if they even ship it at all. I was trying to buy a drain plug for a camper van from the UK and the guy straight up refused to ship it to me. "shipping to the US is too complicated" he said. 2 of the most developed nations on the planet and you can't ship me a $6 piece of plastic?

    belterskelter are you in US or UK?

    Copy what James at Blacksheep has done.

    I just ordered most of the material to build a copy of his in 0.750" x 1" and it's $150 cad (Metal Supermarket here in Vancouver bc).

    I have some 80/20 in 40mm width that a friend gave me for free that I have hacked together a semi jig with and it's not sufficient. By the time I add what else would be needed it would be well beyond what it's going to take to build a steel copy of Blacksheeps's fixture.

    With just a drill press and a couple machinist squares and you can build a clone of the Blacksheep jig.

    Yes, thousands of motorcycle frames have been built with the same style jig. Take some care in building the jig and it'll be a good platform to get started.

    I am in Rossland BC Canada.
    I think so far it's a toss up between the benchmark jig and academy
    But we will see.... The academy is still priced better. Will be looking to make mitering fixtures out of 80/20 for chainstay and seatstay. Will be hand fileing to start.

    If you want a beam-type jig it's pretty darn easy to build your own. There are some decisions to make (fixed head tube vs fixed seat tube) but it's nothing too intellectually strenuous. I imagine with some scrounging and creativity you could put something together for a couple hundred bucks that would work great.

    The downside is setup time. With a few digital angle finders and some magnets, it's no problem to get it setup right - but it'll take you much, much longer than the ~20 seconds with an Anvil. Taking the frame in and out of the fixture will also be more time consuming. That's probably no big deal to most people, though.

    IMO, paying $1000 for that kit is probably not worth it for what you get. But I'm sure it works fine.

    No doubt the Anvil is a time saver for a pro builder.

    I am going for the vertical head tube layout pivoting the frame around the bb.

    Secondary reason for me is that I plan to build more single pivot style full suspension bikes like my last one. I will be able to make a rear end jig on the back half of the flat beam. I'll start a thread once I have it built.

    I love it - can't wait to see what you come up with!

    I think for me, the Anvil is more of a brainfart-inhibitor than anything. Yes, there's a ton of time saved in the setup stage - but there's also the set-and-forget with minimal thinking that really helps me. I have a sort of basic procedure I follow - but the more effort I have to put into basic "easy" tasks, the more likely I am to screw them up (YMMV, I'm a dunce about many things). The Anvil lets me focus my limited mental abilities on other stuff and saves me (most of the time) from screwing up.

    Looking forward to seeing this.

    Have not used it, but I've seen it in person. Pretty badass. Clever design. I think you provide the main beam. The rest of it fits in a smallish wooden box. I use a bringheli.
