    It helps as to which digital caliper you are using too. The (later) Mitutoyo's don't eat up battery power when off. Sadly other brands (including the cheapies) do. These days I try to limit button cell batteries to one or two mitutoyo calipers and either remove batteries from things that only get used occasionally (keep them in the fridge - they last longer) or preferably get 'old fashioned' measuring gear that uses dials or vernier scales.
    SR44 batteries certainly are longer lasting than LR44 batteries, but they still cost.

    Why not just buy them in bulk? They are not that expensive.

    Picked up MEW Issue 274 today. An interesting article on a tool for removing the Myford Chuck, instead of using the backgear to lock it up, which could cause damage to the teeth.
    A continuation of Differential Dividing, for anyone with a Drummond M-Type lathe an article on making Norman Type tool holders. Making split bushes and mandrels to achieve concentric turnings, also a short article on making a Direct Indexing Head from a scrapped Towing hitch. This type of hitch I don't normally see around, it's the ball cast/forged into a fitting with the plate attached ready to bolt on. Fixed flange tow bar, I think they're called.flange neck tow bar.jpg
    For those that have a Mini Mill, fitting a power feed to one. Plus an index of issues 261 - 272
    Hope this helps someone.

    Kryn you'll see a lot more of those UK European hitches about as Aussies towbars can't be fitted to many European cars. Viods warranty no where to attach them to.
    They are useless hitches for our conditions and size of towed stuff.

Grinding with CBN (Cubic Boron Nitride), an alternative way of bolting down a drill press vise, a carry on article from the precvious issue on constructing and using stepped chucks and a concluding article on making the cam grinding machine
    There's a short article on Gib tightening and in the same article, on machine lighting.
    Hope this benifits someone.

    Picked up the latest issue 279 today, and it has some good articles in it. For those that have a Myford or 2, making a tailstock dial for it. Fine Feed Gears for the Mini Lathe, an interesting article on choosing Collets, and for those that like to make items for their shed, Constructing a workshop crane, making a powerful Carriage Lock, and a Trammel for Marking out.
    Also the conclusion of Living with a SX3 Milling Machine.

    Default Issue 280

    Issue 280 is now out. Several interesting articles, making your own Sine Bar, a Carbide Insert tooling for small lathes, miniature bearing puller, tips for turning Acme Worm threads. Adding a tailstock micrometer dial to a Myford S7 lathe, an interesting article on the usefulness of ER Extension Spindles, and finally a couple of articles on converting a Colchester Bantam Mk1 from 3 phase to single phase, utilising the original switchgear and Variable Frequency Drive for the Myford S7.
    Hope these are of interest for someone.

    Default MEW Issue282

    Some more interesting articles in this issue, making a Hydraulic press, a simple Myford Lever stop, to prevent it falling backwards when released, a secondary hand wheel which replaces the projecting handle, a sliding chop saw utilising a 4" angle grinder.
    An article on how to use/utilise a disc brake to make an 11" rotary table.
    For all those that want to design and build a lifting beam for the workshop there are formulaes on how to calculate your SWL (Safe Work Limit) Michael might like to read that and advise if the calculation formulae is correct.
    Anyone that has a "D" Bit grinder or "Universal" Grinder, a way to modify it to become more universal by adding some easy to make tool holders.
    Also a way of removing bearings that connot be accessed from behind. There was a similar thread posted recently about this subject.
    Plus the usual continuation of Lathework for beginners.

    I take no responsibility for the formulas in MEW (or any other publication) being either correct or incorrect and will not advise anyone as to whether or not to use them. I have not seen those formula and have no plans to review them. Anyone using said formulas without correct training and understanding of them and their application do so solely at their own risk, and are advised to consult with an engineer with structural or mechanical experience if they have concerns.
