|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
|Thread: Surplus subjects learnt at school.|
The subjects I enjoyed most were those taught by engaging personable teachers with a genuine concern for their pupils and where the subject matter coincided with my own admittedly narrow personal interests. Despite an interrupted secondary education - two grammar schools with a comprehensive in the middle - I was always destined to be a Jack of All trades
How I wish the Internet had been widely available and accessible 10 years before it was, I try to learn "something new" every day - I dread the prospect of retiring but welcome the prospect of being able to spend time on things I enjoy
|Thread: Aircraft radio scanner|
Two frequencies of particular interest are the distress ones: 121.5MHz and 243.0MHz
Don't ever transmit on these by mistake as the transmitter will be pinpointed by direction finders
|Thread: Hemswell Cliff, Lincs|
Hemswell is hit-and-miss - it's a place I regularly visit particularly the car boot, often there is a chap selling engineering stuff and another selling offcuts. Usually the good stuff coincides with the Antiques fair at Newark Showground
Not forgetting the weather, it is Lincolnshire after all...
|Thread: Using a lathe|
A friend of mine is a Managing Director in an investment bank, he tells me his bonus is tied to the number and severity of outages in his domain. His simple answer is to tightly scrutinize all changes and reject all but the absolute minimum ie mandatory software upgrades, patches and functional changes his business users scream for
Risk management is more about perception than reality, as many risks cannot be quantified, no change does not equal no risk, but for some, it's close enough
It is impossible to impart a healthy respect for machinery unless one becomes hands-on familiar with its operation and potential dangers, we are not doing the next generations any favours by keeping them away from perceived dangers, much better they hang around the streets causing mischief...
|Thread: Multi faceted drill bits - really necessary?|
@Andrew Lyner - you make an excellent point
I dipped my toe in the water with an inexpensive lathe to see if I would like the hobby, as a consequence, bought cheap and made some "bad" purchases initially, I like to think I am making better purchases now primarily from reading posts here
Back on topic - thanks to those posters imparting information - appreciated, I now have Dormer A002 on my wish list
|Thread: Electronic Noise and ARDUINO|
Are you using screened cables between sensor and Arduino? I suspect pickup on cables
|Thread: Easy Button Die Storage Solution|
Good idea, well executed
|Thread: Model aircraft pilots angry over drone laws|
Just seen this on BBC News
|Thread: Warco GH600|
I'm sure you have seen several threads on "What lathe to buy" on this forum already
From my limited experience, it would be helpful to know the proposed use, do you intend to work on motorbikes or scale model engines for example - what do you mean by "smallish parts"?
Warco have an open day this coming weekend (I think)
Here's my thoughts on my WM180: https://www.model-engineer.co.uk/forums/postings.asp?th=141354

|Thread: Use a router for a mortice lock|
Souber mortice attachment for drill, it's what the pros use
Alternatively, mallet and chisel after boring out for the body of the lock
|Thread: Tom Senior spindle bearing lubrication|
According to the manual I have for M1 and Major:
Slides, Feedscrews, General Lubrication - Shell Vitrea Oil 33 / Castrol Perfecto NN / BP Energol HP30
Gearbox - Shell Vitrea Oil 37 / Castrol Perfecto RR / BP Energol HP40
Spindle Bearings - Shell Alvania Oil 3 / Castrol Spheerol A.P.3 / BP Energrease L.S. 3
Vertical Head, Rotary Table - Shell Alvania Oil 2 / Castrol Spheerol A.P.3 / BP Energrease L.S. 3
|Thread: Chernobyl TV Series|
Thoroughly gripping story brilliantly depicted, deserves every accolade, makes very uncomfortable but unmissable viewing
Enjoy is the wrong word, but I certainly appreciate this series and hope there is a follow-up on the long term effects and cleanup efforts
And maybe a series on Fukushima too
|Thread: DC motor + speed controller|
Check out YouTube - Clough42 - developing an electronic lead screw
|Thread: Lathe improvements?|
There’s a chap just started a series on DIY ELS on YouTube - search for Clough42, makes very interesting viewing. He explains the issues very well and is developing the series as he goes, for example, has moved on from stepper to hybrid stepper / servo motor. I’m waiting for him to complete the series then either purchase a kit or plans depending upon how he chooses to monetise his IPR. His electronics knowledge is deeper than mine and has already saved me from wasting a lot of time, what’s more, it looks like his software is available under an open source licence
|Thread: Oh Dear, I've blown the chop saw...|
You could measure resistance across commutator windings to satisfy your curiosity but frankly it's dead and needs to go to Silicon heaven
|Thread: Unknown tool|
Let's hope it isn't British Steel, Scunthorpe, on my doorstep, but I work in London!
