I've got a cheapo HF metal bender that I use occasionally for making small brackets from flat and round rod.

I don't use it much but I've have managed to bend everyone of the pins/rods that hold the dies in place. Kinda funny that I've bent the pins but the bender overall is still holding up well.

I need to turn some new pins on my lathe but I have no idea what type of steel to use. Maybe I'm just over thinking?

4140 would be OK .I like A-2 also . Youre pins were probly 1020 Hot Rolled or 1018 Mild Steel. Even some O-1 would be better than the Unit came with.

Can you just buy a box of dowel pins of the correct length and diameter? www.mcmaster.com has standard, oversize, undersize, hollow, pull, metric...you ought to be able find something that would work.

I think they need to have a flange.
I second 4140HT

Would it be possible to use some grade 8 bolts?

Farrier, you can put harder pins in but you can bet that if the pin doesn't give, something else (more expensive or harder to find) is going to. It is likely that those pins are made of soft material so they will act as a failure point to protect those more expensive componants.

I'll try some 4140.

I've only been turning on the lathe for a few months so I'll use any excuse to make something from scratch.

Thanks!
