Does anyone know of a supplier where I can get frame lugs to do a build that has larger tubing than a standard bicycle? More for motorcycle, motorbike, or tandem bicycle application? I couldn't find much of anything. I'm just curious what is all out there for heavier duty or larger diameter frame lugs as I'd like to purchase some.

Welcome to the forum, ER.
You've come to the right place for help but unfortunately I'm not quite sure what you're asking for. "frame lugs".
Can you be more specific? Engine mounting hardware maybe?

Castings would be more appropriate, to braze the frame tubes into, rather than welding the tubes in.

Thanks Buba, so basic, yet so effective... I'm envisioning my tubing at 1.5" or so, I actually have a few other ideas now, so we'll see.

The Timeless motor company makes exact replicas of early Harley's and now Merkel's built with traditional cast steel lugs and braised tubing...

And another builder here was able to buy just a single large drive pulley from them. So perhaps they would sell just the lugs? Although I don’t imagine it would be inexpensive.

The old motorcycles did use tubing slightly larger that the vintage bicycles must of us use for creating our builds.

And then here’s a impressive approach being done by new member JonesL...
