    Tumbler reverse gears HELP

    Not sure whether you've seen this but Tony Griffiths at Lathes.uk has a write-up covering Advance Lathes here: http://www.lathes.co.uk/advance/ Per the article early models were a bit crude but later ones were decent machines. He suggests that tumbler gearing was not standard equipment but an...

    Proposal for "fixing" chuck - would this work?

    He, he, it seems that these chuck truing fixtures are not just the products of the fevered minds of hobbyists. NASA, no less, has posted a design: NASA OK, it's more elaborate than the ones referenced by Charles Lamont and I but in essence follows the same principles. Joe

    Ive stripped gears in the head of chester conquest, please advise!

    The Chester Conquest here: http://www.chesteruk.net/products/detail/2 — seems to be pretty much the same lathe as the Arc Euro Sieg C3 lathe here: http://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Lathes/Model-C3-Mini-Lathe/Model-C3-Mini-Lathe So, disassembly of your lathe's...

    Proposal for "fixing" chuck - would this work?

    How are you going to stop the superglue setting at some intermediate stage while you're doing the first reassembly — like leaving the chuck seized solid when you've only inserted one jaw? Have you got super-slow-setting superglue? PVA for metal-to-metal joints! What's wrong with 'traditional'...

    Aluminum for steam engine?

    Myfordboy's video series includes one where he: 1. Machines a circular trough in the rim of the aluminium flywheel he's cast, and 2. Encloses the rim using a large jubilee clip through which an entry hole has been drilled, and then 3. Pours molten lead into the all-round cavity to provide...

    New Mini Mill available

    This looks to be the Grizzly-badged version of the Sieg U1 unit reviewed by Frank Hoose here: http://www.mini-lathe.com/Mini_mill/Reviews/U1/U1.htm Joe

    Power Hack Saw Flee Market Find

    Hi Ironhorse, I paid £60 which at the then very low £—$ exchange rate equates to about $80US. I don't know what the cost of industrial machines is nowadays but the only hacksaw machine aimed at home users I know of is the Sieg unit marketed by Arc Euro — see here...

    Power Hack Saw Flee Market Find

    Don't know if Ironhorse has had a chance to open up his machine yet but perhaps I can answer since I had a look at the innards of mine years ago. The motor output shaft carries a small spur gear that drives a larger spur gear within the gearbox housing to achieve speed reduction. On the...

    Power Hack Saw Flee Market Find

    Just posting to say that there is at least one other of these saws around! I bought it new around 1984 and after 30 odd years it's now a little timeworn. Still works fine within its limitations, though. In some ways it's rather crude — the automatic cut-off is simply a bolthead on a bracket...

    Prazimat DLZ180 x 450 help

    Hi, As you'll see from this thread, 'Dr Jo' has one of these lathes: http://www.homemodelenginemachinist.com/f15/my-shed-15623/ Suggest you send her a 'private message'* to see if she can help. Joe * To send a private message, click on 'Dr Jo' in the top left hand corner of the post I...

    Electronic leadscrew for my lathe

    No probs. Anyway, sorry for taking your thread off at a tangent. Joe

    Electronic leadscrew for my lathe

    No, the Kwackers project is for a standalone, boxed controller independent of a PC just like the Division Master. Here's a link to a build described over on the Madmodders site by 'craynerd': http://madmodder.net/index.php?topic=2242.0 Here's a U-Tube video outlining a build by M...

    Electronic leadscrew for my lathe

    I don't know how adaptable picclock's interesting interesting project is to the jobs you've queried — maybe he'll comment on that in due course. You might like to know, though, that there's that there's a mature and reasonably cheap electronic controller project for dividing heads/rotary tables...

    Myford chuck Guard/Shield

    Excellent idea! Can't say I'm in the market for a chuck chip deflector but your idea could be used to make a wheel guard for a home made T & C grinder. If this was based on using, say, a 4 inch face cutting wheel, a milk pan would probably do the job — these can be obtained as small as 120mm...

    lets speed things up

    Hi hudmut, Like you, I'm carrying out a project that involves running a 4-pole 1350rpm motor at twice (or more) its rated speed. Being similarly concerned whether this was safe, I looked at the manufacturers' spec sheets for my motor and similar types. The specs included the bearing types...

    Bore Measuring

    Hi, I've read this thread with interest but I don't think I've seen an inside micrometer mentioned: I picked up this Mitutoyo unit secondhand on EBay about a year ago for around £20. Although I have T-gauges and small-hole gauges I've never really got the right "feel" for them so I thought...

    Wales

    Hi Ralph, No disrespect to this forum but being North American based, I doubt whether there are too many people here familiar with the Welsh scene. Perhaps you'll get a better response if you post your query on a British model engineering forum — here, for instance...

    Collet sets

    Lucky man! I wish I could see a consistent theme in the handling of UK customs charges. My recollection is that they apply duties on goods worth £18 or more but I've heard of a few cases where goods worth more got in "under the wire". Maybe the point of despatch affects the issue — my goods...

    Collet sets

    Hi If this is your first buy from a Hong Kong seller there are a few points you might like to bear in mind: 1. What you see as the price/postage isn't what you'll eventually pay. Likely additions on entry to the UK are: (a) VAT (on the cost price if I recall correctly, not cost plus postage)...
