|Thread: Beer and Grapefruit|
|Thread: Cost of mini lathes|
|Agreed Re the capacity of these machines to open up the world of hobby engineering. As a teen I was besotted with engineering and lathes. I'd have killed for one of those mini lathes back in the 80s.|
|Joking aside, it just depends what you want to do. They can be of very variable quality. A friend of mine bought one and it was junk. Then my uncle bought one fir Model Railway use and it was OK.|
|They cost a lot. Because you will soon realise it's limitations and need to buy a proper one.|
|Thread: Couple of things at Lidl|
|V8eng my local Lidl still has inverter welders. If you want I can get one and post it to you. Reimburse me for the cost and the postage. |
|Thread: Aluminium thread strength|
|As others have said, on 8mm thick material a nut and bolt is the answer.|
|Thread: Myford Super 7 metric change gears|
|Just for interest my friend Richard Oakley can 3D print any gear you may require.|
This is done using a FormLabs SLA machine. The print medium is a high impact resin similar to Paxolin.
|Thread: Aluminium thread strength|
|It's nice to see a reference to MIL HDBK 5J. I thought it was just me that used it.|
The case of the bolt threaded directly into aluminium is really dependent on what you want to do with it.
If you are building air or spacecraft or a nuclear reactor, then use an insert. If it is for a jobbing task in the workshop or home then threads into the aluminium will be fine.
I've seen threads directly into 6082 T6 take loads measured in tonnes.

|Thread: Which books|
|LH Sparey's book is very good. Most of what he talks about in the book is done on Drummonds, so seems like a good book for the smaller lathe. |
Lathework, a Complete Course, by Harold Hall is also very good. It's a Workshop Practice series title. I too have Chapman, from over 30 years ago in training and still excellent.
I'm going to suggest something else that is not a book. Machining is inherently practical. Watch some of the you tube machining channels.
In my opinion the best one is a guy called Doubleboost. He is British and he is very down to earth and does some interesting projects. His channel is Sunday Night Night Cap. Puts out a new video every Sunday. The old ones are all archived. Highly recommend - equal worth to reading several books.
|Thread: Cheap LED rpm modules|
|Quick search on led tachometer threw up four from bang good all under a tenner.|
|Yes Led and tachometer. Got mine from Amazon. I just put one on my Harrison M250 during a vfd conversion. It works a treat. You can read all about it over on the mig welding forum, under "A Vfd for my lathe"

|Thread: Mercer British|
My brother got a new to him Emco lathe and it had a dial travel indicator on it that needed a service.
He enquired of Doubleboost Re Bob and he did the job for him. To say thanks my brother sent some bits, a few drills, de burning tool, circlip pliers I think, which the Boost used in one of his Sunday give aways.
|Doubleboost who posts on you tube has a friend called Bob who refurbishes and repairs dti's and the like. |
You could try asking Doubleboost to see if his friend would have a spare part. He is usually very obliging.
Doubleboost is generally found on the mig welding forum, as am I.
|Thread: Increasing cost of entry into model engineering|
|I don't mind you tube reviewers making a bit of commission on stuff that gets sold. They've shown me what I can and can't buy with some degree of confidence, so fair play to them.
Neil, I remember last year you reviewed a lathe in the magazine from Arc. I take it you got to keep that machine? So all's fair then
Just to be clear, I've nothing against any UK supplier. I still use them. You'd want your head examining, I suspect, if you bought a sight unseen rotary table or similar from bang good. That said, for things like inserts, it's great. Especially if I can watch someone demonstrate them working well.
I found out about bang good from a slightly different angle. An electronics enthusiast friend showed me it as a place to buy small electronic modules, the type of stuff you'd use with Arduino. Much cheaper, again, than UK based suppliers.
I used a little relay module from there in my current VFD conversion on my Harrison M250. You can read all about this over on the mig welding forum. It's in a thread called "A vfd for my lathe".
Hey. If Arc can plug his stuff here, I can plug mine.

Point taken about the bad reviews and so forth. However, if I watch someone who is taking a heavy cut on a piece of stainless round bar and the insert is performing well, then I can choose to buy that tool. If he does something else with another tool and it doesn't perform, then I don't buy it. That is the risk taken out of it for me.
If the tools don't perform then they fail the review. There is very little you can do to fake that. OK so you tubers get a small income from making and editing videos. I get a great deal of pleasure from watching them and I get a lead to a good supply of tools. I don't begrudge them the income, wish I could do the same. Pay for bits for your shop by making a few videos, be great.
|I wouldn't buy a mill from bang good. But then I wouldn't buy one from Arc either.|
In my original post the point I was trying to make was that you tube reviewers are helping the likes of me-and dare I say it us-to save considerable sums on the bits and pieces we need. My recent tooling acquisition is a case in point. I bought the ones I saw reviewed, so I knew they were good and fit for purpose. I saved by an order of magnitude on my old suppliers price. And the quality and function was exactly the same.
How do the UK suppliers gauge the products they are buying from the same Chinese factories?
|I have a small hobby shop with a lathe and mill, well actually two lathes and two mills and some tig welding gear, but still small really. In there I indulge my favourite pastime of making bedding for my stainless steel hamster.|
I want decent quality tooling that serves me well but doesn't hurt my pocket.
The individuals on you tube who have machining channels and review kit from the likes of bang good are a God send to the likes of me. They don't receive payment - unless you count getting to keep the tools they review - and they give the stuff a good work out so any flaws become apparent.
I just bought a set of 16mm toolholders and some inserts from bang good off the back of a recent review. They are excellent. They are no different in quality to the ones I'd purchase from all the usual UK suppliers except in one very important regard. They are a fraction of the cost. And by a fraction,I mean about a third.
I also needed an ISO 30 chuck recently. I bought one from bang good. It is excellent. Negligible run out, well made and finished. Does me proud. It was considerably less expensive, by an order of magnitude, than the same or basically identical product from the usual UK sources.
So essentially if you want your hobby machine shop to not break the bank then you have to shop carefully and you'll get quality items from the likes of bang good. You are buying exactly the same products from exactly the same factories that the UK suppliers do. They then stick their large mark up on it.
|Thread: Mini lathe 3 phase AC conversion|
|Perhaps you need to consider a bigger machine with more capacity.|
|Thread: A delta motor running in star config.|
|Just get and fit a smaller motor. Right tool for the job and all that.|
|Thread: Pressure as a unit of time|
|Re the idea that people have been converting pressure gauges to other things for decades...people have been committing murder for millenia, it doesn't make it any less wrong!|
I'd not make a clock to gauge conversion using pounds per square light second. That would be mixing units.
I've had enough now, I'm off to the bar...
