We've just got back from a break away, during which I had two days (the second of which was over 11 hours long!) at a blacksmith's forge making a knife. It's still got a lot of work to do...
It started as something that looked a bit like this (not my photo - just something I downloaded from the web):
It got made hot a lot and got hit a lot (first with a power hammer and then with a few different types of hand hammer) and twisted a lot with a leg vice and a clamp.
After a lot of that sort of thing, it ended up looking like this:
It then had a lot of (belt & angle) grinding to make it look like this:
For a sense of scale, that's a shade under 400 mm long.
After hardening, a bit more grinding and then tempering, it was time for about 3 hours' worth of hand sanding, which I didn't enjoy very much.
It was worth it though. After all the hand sanding, it went in a bath of ferric chloride for half an hour.
I'm loving the way the pattern goes around the bolster and up onto the blade...
It now needs to go in a bath of (and I quote) the "cheapest, nastiest unfiltered instant coffee you can buy, made to the consistency of gravy" for four hours, then I need to sharpen it and try to fit the wooden handle sides without damaging that wonderful pattern.
I'm not sure I'd want to make another knife again after all that hand sanding, but I'd definitely be tempted to have a go at some other types of blacksmithery at some point in the future. That part of it was great fun.

Nice. What does the coffee do?

Apparently low quality instant coffee is a little bit acidic & it helps to bring out the contrast

Helped someone out with a Fobco handle lock and a couple of stop nuts. My knurling is still rubbish:

It can defy best efforts, on occasion.
I run my lathe on its slowest belt speed, & you have to be firm at feeding/tightening the knurls. Try being timid, & they generally look rough. I use WD40 as a lube whilst knurling. Give the piece an occasional spray.

Will give lubricant and a slower speed a try Thanks
I use thick oil for knurling. Also I start with about half the knurling wheels engaged on the work and then slowly move it along and back again a few times, keeping it engaged the whole time until you’re done. That looks like stainless though - very tough to knurl as it work hardens.

I have never really had much issue knurling, usually use the flood coolant running on it (more to stop the knurl seizing as they are old crap ones) and just plenty of pressure on the knurls.
Here is a stainless one I did a while back.

Drilling table for mill.
Made entirely from scrap. 5mm plate and 50mm x 5mm equal angle.
Just need some t nuts, studs and washers sorting.
I've left room all around so I can clamp to it using mole grips.
I don't have a drill press since I got the mill. I will still use my nippy vice directly on the mill table. But anything hand held or that I can clamp to this, it
should make things easier.
I did use arc welding for this. Good practice for my fillets. I struggled with distortion too, I had to beat it back into shape!

Lubricant makes a big difference. The knurl dislodges bits of material from the stock and if you don't lubricate, they get stuck in the indents of the knurled part and the next time it gets to the teeth of the knurl it gets mashed. Lubricant washes all the crud away.
