2319 forum posts 13 photos | I haven't trawled through all your links but if one of the named suppliers has the courage to state an actual accuracy figure rather than just 'precision' I would go for them, if in the future they are not as described you can get a refund. Loads more advice will follow shortly from different forum members. Tony |

They are 1⅜ " square near to 35mm, so might suit your purpose, but how precision is ultra-precision?. RDG sell a varied selection of sizes - the smaller ones without the clamping facility. You don't state whether clamping is a pre-requisite. John

![]() 317 forum posts 23 photos | These occasionally appear on car boots - Hemswell (north of Lincoln) had a regular stall with quality tooling I guess it depends upon perspective - I bought stuff with the expectaiton of learning so it doesn't matter if I dink it - actually, it does matter, but I get slightly less annoyed than if I had paid a fortune And to John's point, do you need ultra precision assuming one has the means / skills to measure...? I know I haven't mastered this yet |

7517 forum posts 20 photos | The main thing putting me off is that I would like to have a smaller V one side. I looked at that one and it does appear to have a smaller V one side, or even a larger V one side - it’s all relative, I suppose? Edited to add that all the hardening in the world will not prevent you from dropping them! Edited By not done it yet on 19/04/2021 15:17:55 |

![]() 25215 forum posts 3105 photos 1 articles | You don't say over what length you need that 0.001" accuracy ? 1" , 4" 12" Don't think I would bother with the Blue Fox as they could not even fit the clamps the right way round! I think most will be within the spec you want, these ones of mine which came from Chronos I think are only a couple of tenths (0.0002" ) out over their length with my measuring equipment Edited By JasonB on 19/04/2021 15:50:30 |

10668 forum posts 2415 photos | Slight worry about the precision requirement - does John need more than a matching pair? It's easy to manufacture two almost identical V-blocks by grinding them together as a pair. So even a cheap pair of blocks should match accurately, and two blocks are usually all that's needed. V blocks don't have to be an exact dimension unless three or more are needed together. If that's the case, look at high end precision blocks, £££. It's the multiple precision part that's costly, rather than what they're made of. Much depends what they're for of course, but I avoid expensive tools for ordinary work because accidentally damaging them in the rough and tumble of my grotty workshop is so painful. I only buy expensive tools when essential, and they are cosseted for special occasions while cheaper tools do the work. Cheapo tools are ruthlessly replaced, which isn't often because I don't have to meet thrash-the-tool production targets. Ought to admit I see tools as expendable, not heirlooms: others positively enjoy handling quality tools, if that's what's wanted, go for it. I got my inexpensive blocks from Machine Mart (VAT free day). In the same cost class as John's examples, they're fine. Although 'pretty accurate' and 'hardened', I take care not to drop them! One point that may not matter, but the clamps on expensive sets are usually (I believe) made of steel. whereas those on cheaper sets might be alloy. The blocks themselves appear similar - never had the chance to do a scientific comparison. Tin hat on now. For what it's worth, I don't recall any V-Block quality complaints on the forum. I expect a barrage of examples will promptly descend on me from a great height. Watch this space! Dave |

![]() 3676 forum posts 82 photos | If you buy blocks from the classic toolmakers like Moore and Wright, Starrett etc. Then they will be a matched pair with matching serial numbers. Many second hand blocks will have very low mileage and should meet your spec. But check the numbers. Buying new at the economy end of the market is going to be a risk, I would be looking to buy from a supplier that is interested in maintaining their reputation for acceptable quality at a reasonable price.

Same discount to callers (when their premises in Dunstable are open) MC Black |

One might ask “why the grooves along the sides?” Does the price reflect only the single sized V. Is the buyer expected to make their own usual type of U clamp? If the through-hole is for securing it in the vertical, it looks very close to the V. Are there any precision dims provided for standing them on end? Definitely look like those are cheap for more than one reason. I would fear that ‘ultra precision’ might only apply to one isolated dimension. Dimensional description, or lack of, is important for some - but clearly not for many purchasers. I expect my V blocks to work accurately in all orientations. But I do have some odd ones that are often ‘close enough’ for the use to which they are put. The angle of the V is probably the least important dimension. |
