Dispatched to Johnathan.
I've ordered the one from Amazon in the link. I'll give it a go and report back ( although someone might need to give me a nudge to remind me!)
Well so far, mixed feelings. The concept is good, it goes together easily and appears to be a cheap solution to the problem. No instructions, and within seconds the belt seems to run sideways off the rollers. Maybe something isn't right, I've no experience with power files so I'll need to investigate. Stand by....
I bought an evolution one like Jonathon's. Just been using it to fix a chipped edge on an axe and had brilliant results and not much heat generated.
I used a big G clamp to fix it to an aluminium step up so I could hold / control the axe head better plus doing in the garden doesnt deposit hot metal filings over the cars in the garage!!
Earlier in the week I used it to smooth a small area of brickwork to mount an outside tap, which it did in seconds.
They are versatile and useful!
I thought I'd provide a little update. The amazon one is actually not bad, the belt has a tendency to come off, but there is a tensioner which helps to adjust it, if it does come off it's only a matter of a few seconds to re install it. For an occasional user like me, and for the money, I would recommend it. Just don't expect too much.
