Don't get me wrong I am not knocking the Chinese Digi-callipers, I think they are marvellous and I have about 8 or 10 around the shop. Every machine in common use 'should' have one but what happens in practice is that the most used machine has six :scratch: However once you know the limitations they are easy to work round, I tend to get close with the callipers, then swap to micrometers if needed, things like bearing diameters need to be spot on so it's micrometers to finish. Tomorrow I have to make 3 long shouldered bolts with three diameters, 25mm, 22mm and a 20mm x 2.5 pitch thread, none of these diameters, lengths etc are critical and I'll use the digi-callipers for everything. No point working to tenths when not necessary, it cost money to do this and it's usually my money so that's a big incentive. :beer: My complain with the 350 was jittering and because it was on a lathe, the accuracy. I have a Sino readout now and it works well but I still don't rely on it all the while, my main lathe a TOS 14 x 40, is now about 10 years old and still deadly accurate on the dials, if I put 0.025mm on it will remove 0.025mm from the diameter. The Sino will follow this the 350 wouldn't. |

--- Quote ---The tape was free but I subsequently got some more from Allendale. I think it was very cheap (2 metres for £~20, ISTR). --- End quote --- John that 'tape' is exactly what I've been looking for - still am ;) I can't see it on the Allendale site, do you have a link? Bill [edit] Ah ha found it ----- out of stock ! :( :bang: BTW JohnS I still intend to experiment with an optical mouse or encoder based digital trava-dial, but I'll continue it here, as there'll be less chance of bumping in to an know-all/nothing idiot ;) |
