That job would take up a lot of your Tile time-I thought you retired?Now I think your are a type A guy like me who likes a lot on your plate.
Throwing sinks for me was a phase I moved thru-custom work, sinks with matching ceramic handles on the faucets . Now I just say NO.
I did that for some clients who built custom homes. Now not enough money on planet for me to make a sink.Since my wrist surgery I need to do less with wrist not stress it more.I am settling for smaller forms. I already did the huge stuff in my career no need to do more of it.
Its funny the progression of throwing is always towards the larger forms-now it means nothing to me.I can appreciate a small well thrown pot more than a huge ugly vessel that screams its BIG but thats all.
Back to sinks they require lots of things to get right especially the overflows.
