Yes its done quite a bit of cutting and teeth still bloody sharp. Unsure where to buy replacement discs they dont seem common, 1.1mm thick (how it cuts with a tiny battery) 85mm, 15mm bore.
The trouble with a lot of these flow switches is they need a fair flow to operate. For example that one in your link needs 6-7lpm and I don't think that much goes to the torch.
It does have a fan but it is not integral to the motor, just a 240v fan fitted to the cooler.
The bore is already only about 3mm at the torch.Reduce the bore & the increased flow rate will be metered as greater flow volume.
Did this very same mod to my lathe. I also made a solid post to replace the compound slide. I only put the compound slide on when needed now. Which isn't very often. Both mods were from journeyman's workshop website. I also did the mod to disengage the banjo that carries the change wheels, so they only run when needed, this is a great modification.Not today, but I got this finished last weekend. After chatting with @Pete. this morning, I decided to post up some pics!
It’s a 4 bolt compound slide clamp for the 920 mini lathe. The standard 2 bolt affair is said to rock somewhat, although I can’t say that I’ve ever noticed it on mine. Anyhow, it’s supposed to be a very worthwhile modification, so I thought I’d give it a go.
I screwed up a little at the end, as I didn’t notice that the bandsaw bow was off square slightly, so after it was squared up in the mill, the graduated swivel is a little more exposed that originally expected, but it won’t affect the way if functions at all.
This is the 2 bolt original clamp:

It's made from a bit of plain 15mm mild steel, so I was quite pleased with the finish I got. It was the first time I'd 'properly' used the mill so it was all a bit of trial and error and guesswork with regards to feed speed and tool speed, and I also discovered that a higher spindle speed on the lathe gave a better surface finish, so all in all I learnt quite a bit on this job! Happy days!
Next up I need to make a couple of new T bolts for it, as I'm just using ground down M6 screws at the moment, and I think they need a little more surface area to prevent the heads digging in to the T slots.
Also judging by the photos it looks to be sitting a little ****** on the cross slide, so I'm hoping that it will square up when I get it screwed down properly.
That looks like a very interesting site - I’ll have a good look later on.Did this very same mod to my lathe. I also made a solid post to replace the compound slide.

The bolts were converted into Grub screws, loctited into place and preened over the make sure they don't come loose.
