    Tube sets

    I would like to dip my toes by building a bike with a tube set and lugs. I found a 26" frame set with lugs on Nova, but not a 29" wheeled version. I found a 29" set on Henry James, but cant tell if it's lugged or not. Does anyone have a recommendation? I'd like to build it SS so adjustable dropouts would be key.

    You're going to have trouble finding lugs that will work well for a 29er, unless you are looking to build a "monstercross" style of bike.

    The HJ recommended tube sets are not for lugs because they use big tubes and there just aren't people making lugs in angles that work well.

    If you want to build a 29er and you have the brazing stuff, just go for fillet brazed.

    I'd get the cheapest tube set you could find......maybe two sets......and then have at it with a file, saw and torch. I would also consider grabbing some scrap metal, or maybe a small shipment of straight gauge 4130 from Wicks to practice your fillets if you haven't made any before.

    I'd probably opt for some cheap track dropouts too on frame #1. I'd hate to ruin a set of $100+ paragons or similar.

    Thanks guys. I'm decent at brazing but was going lugs to short cut using a jig. Is it possible without a jig?

    If you do some googling you'll find some lugged 29ers build with the Llewellyn "Slant 6" lugs, but they're not useable out of the box - people usually have to do some manipulating on them, flip the seat tube lug, etc. It's not a shortcut by any means and you're on your own at the bottom bracket.

    If you also do some googling you should also find that there are lots of resources on framebuilding with minimal tooling, such as this one. You can do a lot with some angle iron or surplus 8020.

    Even a minimalist jig is still a jig, but yes it is doable without using one of the more common expensive jigs. Lugs do present some advantages and disadvantages, but I build my lugged frames as though there were no lugs and then add the lugs. All your miters should still be flush........although we would never know how bad your miters are with lugs covering them. :

    I build off of a flate plate of granite with Alex Meade blocks. You could easily fab up something similar.

    Interesting with the blocks. I definitely have some choices to make.

    Do you have to shim under these blocks or are they specifically designed for the tube diameters you are working with? I am looking at trying a frame using this method.

    Jay, check this forum out: Jigless Frame Construction

    The 5th post on this thread is what I just used and it worked nicely. It's about $20 in materials at The Home Depot, plus it's easy and quick to make.

    Also, your screen name suggests you may be from Castle Rock, CO. Am I right?

    I believe those were custom - I don't see Alex Meade listing them on his tool page.

    Edit:

    The whole flat plate system is here.

    This is the way I'm leaning and yes I'm in Castle Rock CO. Just returned from riding Indian Creek.
