Here is a list of all the postings Carl Wilson 4 has made in our forums. Click on a thread name to jump to the thread.
|Thread: cutting the bar of a digital calliper|
|That's meant to be a pound sign not a question mark.|
|A friend of mine has just fitted a DRO to his XYZ 1440 lathe. He got the DRO from Ali Express. It has cost him ?150 inclusive of ?18 import tax.|
|Thread: Electrolux vacuum - Need to make a missing wheel|
|The first question in maintenance is is it worth repairing?|
|Thread: Storing Machinery In Damp Conditions - Advice Please|
|Common or garden waxoyl. Used it in the RAF to protect aircraft going into long term external storage. Works perfectly. |
In my second career, have used it to protect non stainless steel components that go subsea. Works a treat, protects against seawater corrosion. Another thing to do is wrap stuff in denso tape. Sort of waxoyl impregnated fabric tape.
|Thread: More collet and milling tools confusion.|
|What about this|
|Thread: What bearings for a submersible wheelchair?|
|316 stainless on ptfe is how it is done. 316 stainless is required due to the high concentrations of chlorides in seawater, and in a pool too.|
|You don't need the complication of ball races etc for a submersible application.|
|316 stainless steel running in ptfe bush. I have extensive experience of this running in seawater. Lasts forever.|
|Thread: Rocol RTD shelf life|
|Regarding the query of the original poster. In industry, oils, chemicals and solvents often have a test date. This is to ensure that no deterioration has occurred in storage and that the product is fit for use. Certainly this was done in the aircraft industry. |
That might be an explanation for the date on the Rocol.
|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"
