|Thread: Seeking advice on suitable lathe|
In view of the number of operations to be carried out you might consider a capstan lathe - one that has several tools mounted on a rotating capstan in the tail stock. This would greatly simplify tool changes and increase both productivity and repeatabili8ty but at the expense of reducing available bed space which probably isn't of great importance for the work you anticipate carrying out
|Thread: How to upset the neighbours!|
'Tis a thing of beauty!
|Thread: Need help with wiring|
Assuming these are the 3 wires:
Brown - Probably +12v
Black - Probably 0v
Yellow / Green - Earth
Measure resistance between Brown and Black, should be a few (tens?) ohms
Assuming low - but NOT zero - resistance, try putting a car battery across Brown and Black, just touch the terminals and see if the motor twitches in the right direction, if not, reverse the wires and retry
|Thread: Non ABS pipe glue recommendation please|
Thanks for all the advice - Martin's suggestion of Devcon did the trick, I stumbled across a tube at a car boot this weekend, wouldn't have known what I was looking at without this top tip
Hot tub holds 4 people therefore lots of water pressure, so far the repair has held up
Outlet pipe for hot tub snapped when moving hot tub, I've tested with Acetone but no joy, plastic is hard white with almost ceramic like texture and brittleness
Replacing the pipe isn't an option unless I absolutely have no choice so I'm looking for a glue recommendation please
|Thread: Hieroglyphics on a Wehlen & Co clock face|
Likewise I am intrigued - and agree it's a bit of a punt with regard to proofreader marks
As for the lasting impression, it may be the markup paint reacted with the white base and over time "developed" despite the markup being removed after lettering was applied, I'm not a chemist...
Happy to be proven wrong on all counts, simply offering some thoughts
Is it possible the annotations are a combination of proofreader marks and manufacturer code?
This site suggests the three horizontal strikes are for capitalizing: **LINK**
|Thread: End Mill Sharpening of Helical Flutes|
I am interested Tony...
|Thread: Blown Fuse|
Is it possible the flash when viewed was behind the tool ie within the motor casing which from the viewing angle gave the impression of being at the tool tip?
An arc sufficient to blow the fuse should have left some mark on the tool tip and work item
|Thread: What method do you use to find center height for your lathe bit?|
Thank you Danny, I've just ground one up and tested on brass, excellent finish with long swarf finer than a hair
|Thread: Serious question, What is a Mini Lathe?|
Isn't "quality" subjective?
Not being picky, pedantic or looking for a fight - I can't afford / justify a top quality lathe or mill yet, I set my expectations on what I can achieve accordingly and as commented, my WM180 is far more capable than I am which points to the "quality" of product this operator produces, not the "quality" of the machine I use
Taking a more extreme view, the pdf recently attached explaining what Japanese POWs produced is simply astounding and far more impressive than anything I can produce - that's what I call quality
The Chinese are very good at taking a long term view, sometimes several generations
India is unlikely to become a large scale manufacturing centre for the simple reason the country lacks natural resources - no Oil, Iron ore etc. Whilst China import huge volumes of raw resource, their command economy, centrally planned infrastructure, opaque financial investments and currency manipulation give huge commercial advantage to local producers
And back to the original question lest this be a thread drift too far...
I think Dave hit the nail on the head with his definition
Frankly I don't care what my lathe (WM180) is classified as, it's what I have to hand (until I fix the WM240) so it is the best available to me. I'm still learning and the lathe is way more competent than I am, doesn't stop me wanting a bigger, better lathe though
|Thread: smooth cut in brass|
Mike - are you using TC tipped or HSS tool? Please attach a photo
What speed are you running the lathe at when approaching 12mm diameter?
What depth of cut are you attempting?
@Zan - beat me to it!

|Thread: Another knurling tool|
Thanks for showcasing your knurling tool David, your design may very well solve an issue as I am considering making a new knurling tool myself
|Thread: My new lathe a Warco 918|
Yeah I guess so, the display itself is digital though the function is RPM whereas DRO (IMHO) is synonymous with distance measurement, at least, that's how I think of it...
Honest guv, I'm not trying to join the pedant club, I know too little
RPM not DRO?
|Thread: Surplus subjects learnt at school.|
@Howi - I enjoy work tremendously so why would I look forward to giving up something I genuinely love?
I have plenty of things to fill my time so I'm not concerned about being bored
|Thread: How badly do I need a surface plate?|
Thanks Dave, very helpful
I'm making 6 similar items which do not need to be absolutely dimensionally accurate but must pass visible muster, so far I don't need a high precision flat surface and caliper measurements are just fine
I'm glad I am not the only one who uses the 'fitting' approach, I haven't yet needed to machine anything to tight tolerance but that's probably because I don't make models - but I have enormous respect for those who do
However, I did pick up an unused granite cutting board yesterday "just in case", I hate Sod's Law...
|Thread: What mills have you had|
Tom Senior M1 - Retrofitted DRO and rev counter, investigating X axis motor for both left and right. Needs a proper control panel and lighting rather than the eclectic kit of parts slung together
|Thread: What lathes have you had?|
WM180 - Somewhat modified and my regular use lathe
WM240 - Need to fix or replace the motor and I expect this will either be sold or become my regular use machine
I will upgrade one to ELS when Clough42 produces his kit
