Lou, I just sent you 3 documents by email. The 1[SUP]st[/SUP] is an introduction to lug cutting, the 2[SUP]nd[/SUP] are instructions and the 3[SUP]rd[/SUP] is a reference for tools and suppliers and helpful links. I don’t charge for them. You might want to read them first before sending me a donation for our Ukraine Bicycle Project .

Yes cut lugs can support significant weight without worries. In England they used to advertise fancy lugs were less likely to break because their greater shoreline length reduced lug edge stress. In reality their purpose was to make frames prettier but that might seem less manly than some logical reason based on physics.

You probably know this but Hetchins is the most famous of the British builders that made frames with fancy lugs. Many other builders from the UK did as well like W.B. Hurlow. I’ve got some of their frames hanging up in my shop to inspire students.
