I liked it so much, I wanted to see if I could create it large radius. I have down to ~9-10% 054, some 063, mostly 072, a little 081.
This will go into my inventory, named the Leikec. I thought the wye was a little awkward and put # 5 to smooth things out on the left. I'll probably refit with Ross switches.
Looking at the 3D, I set the view block at 8". Probably needs to be 10" or 12"
Thanks for a creative design and post some pics while you build it.
