Cheap taps from Amazon?

The haters will hate, but tap guides are great (e.g. https://biggatortools.com/v-tapguide-faqs, but even a block of hard wood with a clearance hole drilled in it works fine).
Unless you're tapping something super tough (306?), Amazon taps are fine for hand tapping. Go in straight, use a good lubricant.
