I’m playing with lug designs while I’m waiting until I can continue with my actual build/setup.
Thought I would drop some pictures here of what I’ve drawn up so far, maybe some of you will find it interesting.
Pair of classic head lugs:
Reshaped the top lug:
I’ll play some more with that asymmetrical detail, I don’t like how it looks yet but I still like the idea.
Playing with ways to make the transition smoother:
This is pretty sweet! Is there any way you could make a little lug design tutorial for us neophytes?
Thanks!
I could look into it if others are interested, just gotta find a good free video editing software for that.
Hananas,
Nice stuff, keep up the good work!
I often kick around the idea of making more castings, but doubt the market is big enough to support the investment.
Still, it really is fun to play with designs. I have some Samson inspired lug designs somewhere. I’ll try to dig them up and post here.
Cheers,

Hi Kirk, thanks!
I’m totally new in this space and I really have no idea what I’m doing yet but I’m experimenting with getting some of these custom lugs 3D printed in 316L stainless to build my own frames with.
So far it looks challenging but doable!
I’m a fan of your work, would love to see more interesting stuff!
Edit: here’s the first set I got 3D printed as a test. I’ll see if I can braze these up when I complete my torch setup.
Nice! I assume those lugs are designed for integrated bearings?
Yes, to accommodate the odd IS42/47 headset that’s used with 1 1/4 tapered Trek carbon forks.
Not sure what software you’re using, but if you can change from Tangency(G1) to Curvature(G2) you’ll lose the worst of those shadows on the fillets. G3 is likely overkill for such small blends.
You’re right, I’m using Fusion 360 and I haven’t checked in a while but I think it doesn’t let me use G2 on chord length fillets. I’ll have to check again because I’m not sure actually.
I could always try unstitching my surfaces and bridging the gap created by the chord length fillet with a G2 loft, but it seems like a bit of an overkill workaround
