Merry Christmas all.
I want to clean up the slug trap threads on a Small Journal Crankshaft.
Can any one tell me what size tap I need.
Many thanks, Iain

Try e-bay, I'm doing this job on a big journal crank at the moment and got a new Dormer 7/8 BSF tap off e-bay for £8 inc postage. There's probably no demand. I got a bottom tap as I wanted to scrape a lot of carbon out the threads.
