Telescopic Bore Gauges | Model Engineer
Posted by Tony Pratt 1 on 18/01/2021 13:40:09: 'This Old Tony' on Youtube did a video on improving a set of telescopic bore gauges, it might be useful having a look to inform your buying decision. I wouldn't personally buy this sort of thing for less than £20, it would end in tears. The Kennedy ones look OK & you can always get a refund if they are a load of rubbish but as they are mainly an industrial supplier you should be alright. Tony Here you go, I was just finding it when you posted your reply; from a couple of minutes in Bill
