|Thread: Shackerstone - Battlefield Line - Outside storage|
Spent a lovely afternoon on the Battlefield Line yesterday and snapped these poorly machines stored outside the engine shed, out of shot to the left look to be 2 or 3 lathes under cover
|Thread: DRO Z-Axis /4th axis "combiner"|
Very well thought out and nicely done!
|Thread: Printing small parts for car restoration|
I 3D print Jaguar X Type headlamp adjusters in ABS which deviate from the original design to prevent shearing across the Z axis - you may find similar issues with parts so some trial and error orienting the physical build will be required
ABS can be smoothed using acetone, this gives stronger inter-layer adhesion and smoother finish, again, some trial and error required
Have a look at Robox printers which crop up on eBay / Gumtree from time to time, US imports are just fine, no voltage issues just a mains lead change. Beware the earlier single extruder models have a tendency to leak, replacement heads are available ~£120 and there are a few other gotchas, nothing insurmountable
|Thread: Machinery Directive and CE marking|
|Thread: Why do we do it?|
Can anyone explain why we need two clairvoyant onions? does the recipe also include eye of bat?
I'll get my cloak...

I'm glad you said that Bazyle, you are now my go-to guy
I have the view that everyone should be welcome to contribute regardless of skill, knowledge and experience - everyone wants to belong to "something" and IMHO it's not for anyone to be excluded
Threads which meander are usually more informative than a straightforward answer. I have learnt an enormous amount perusing various threads which don't immedately answer my specific question but spark further interest
|Thread: Hardinge lathe on fleabay|
That's a big price drop making it very attractive, timing not good for me though
|Thread: Toolroom lathe?|
Thanks thaiguzzi - a very useful point to consider
What is the maximum floor loading of a typical concrete garage floor?
@Martin - some thoughts on using WM180 recognizing these are my opinion only from an inexperienced user, and none of the below prevent excellent results from being achieved
Now the positives, which far outweigh the above
In summary, I'm delighted with my WM180, it's not perfect, but certainly more than capable even in my clumsy hands. Most importantly, a good entry into our hobby and points to requirements for my next machine. Some 3 years into ownership I doubt I could have made a better choice given the circumstances and skills starting point, I just feel it's time to acquire a more capable machine. And I have learnt loads, sometimes it feels like a mountain to climb, but I'm not aiming at being "the best" or perfect, simply sufficiently competent

M300 is on my list along with Boxford AUD and various Colchesters, a visit to 2nd hand dealers with my mate is approaching to get a feel for what may suit me best subject to availability
I may still look at others, I'm not in a hurry to buy
Thanks guys, I am conscious of the wear and general condition issues but appreciate the contextual information
I hope my ex-toolmaker buddy will be able to spot issues far more readily than I will, assuming I can get him to travel
I have approached the Gromatic owner for photos too
I doubt I will ever use a taper turning attachment...
At the heart of my question is whether a sufficiently decent condition toolroom lathe offers any advantage over what could be considered more mainstream ie non-toolroom lathe, maybe I'm getting unnecessarily tied up with semantics
I can't see anything obvious - initial build quality and subsequent wear notwithstanding
I'm not after automation, copying etc but like everyone else, just the best I can get at a sensible price. I don't need to turn 36" items, but 12" is too small, I'm conscious of the general advice "bigger is better" and it's easier to turn smaller items on a larger machine than larger items on a smaller machine
I take on board the potential risk of acquiring a clapped out example - caveat emptor and all that
Precision is something I hope to develop with practice... I am a long way off that yet
I had assumed the term "toolroom" implied use for one-offs rather than production line, so I am educated at least on that point
This is not another "which lathe should I buy thread" as I have narrowed down my "want" list - simply asking whether there is any benefit to acquiring what is advertised as a toolroom lathe as opposed to any other lathe
For example - Smart & Brown and recent advert for Gromatic spring to mind, can anyone explain why a toolroom lathe would be a better (ha - define "better" purchase than a similar size Boxford / Harrison / Colchester
Some context may be helpful, I have a Warco WM180, a great lathe to learn on and in truth I haven't explored all possibilities, and my feeling is I want something with greater than 12" between centres with separate screw cutting lead screw. As mentioned in a previous thread, the lack of a screw cutting gearbox doesn't help either, an in truth, I had to start somewhere and the WM180 was available at a fair price. I don't have a project or specific use in mind for the lathe, just a hankering for something a little larger (up to 36" between centres) and more capable as I'm probably now "borderline competent"
|Thread: Mixing Gear Module?|
Thanks Michael, I appreciate the confirmation
Martin Cleeve is indeed a very clever man!
I do have to seriously think about my approach, Robert's suggestion has the appeal of space saving, less machining and is non-machine specific in it's implementation, worthy of an article when I get my act together
Now that is a very appealing option, thanks Robert, blindingly obvious now you have mentioned it
Time to get my thinking cap on
I have a WM180 and dislike gear changing for cutting threads, there has to be a better way - and yes, this might be academic as I intend to purchase a bigger more comprehensively equipped lathe this year
On the WM180 within the gear train cover space is very limited, as an aside, moving the motor would help. Having looked on YouTube, some of the home-built gearboxes are substantial both in size and weight, which got me thinking
I know the WM180 uses Module 1 gears for the chuck drive, I wonder if I could gang a 40T Module 1 gear with a 40T Module 0.5 or 0.75 gear to reduce the physical gear size then reflect the new Module down the gear chain to the lead screw - I cannot see any great load issues but I might be missing something blindingly obvious, it has been known...
I saw pre-production models in action at New York MakerFaire in 2017 and was very impressed, I have no affiliation with the company, simply spreading the word
|Thread: If starting again, what would you buy with a budget of £5k?|
Personally 2nd hand every time, I'm on a steep learning curve, have no intention of model making just making stuff for my own use (lathe tool holders, tap wrench, modifying my lathe etc) and pleasure of having a reasonably well equipped workshop
I want to upgrade my lathe to a Boxford / Harrison / Colchester when I am in funds, I have a Tom Senior M1 with DRO which is more than adequate for my needs, and an Invicta shaper which is a thing of beauty - another tool to learn how to use, it's an indulgence rather than a need
I would add a decent bench grinder to your list
That should leave plenty of money for tooling and materials - Hopper has given a very good account
As an aside, if you are looking to pick up techniques and skills quickly, the Axminster 5 day intermediate course is an excellent starting point, I wouldn't bother with the Lathe or Milling beginners course having done the Lathe beginners course too
