|Thread: Meddings pillar drill colour|
I actually thought Meddings used blue anyway, they must have changed colours in the past?
I wonder why so many machine tools were painted either Grey or Green? The last Harrison M300 they bought where I used to work was white, if not at least a very, very pale Grey.
|Thread: Why mostly manual cars in UK|
Given the number of road deaths and serious accidents world wide it’s clear that humans simply aren’t up to the job. If you take car ownership away from people completely it will not only cut deaths on our roads but free up time for what many drivers really want to do - look at their phones. It would also cut car crime and reduce pollution. I would expect that fully autonomous cars will be cheap to hire so all those that can’t afford to buy a car would have access to cheaper reliable transport. I could also mention noise pollution and other anti social driving from the chav’s that every area seems to have. Governments know all this and they can monitor where everyone is at any given time so you may not like it, and many won’t but it’s coming at some point whether the public like it or not. From what I’ve read though many young people already dislike the prospect of spending a large part of their income on a metal box that spends 95% of its time outside their house or workplace. Attitudes change but it’s often the elderly that get so stuck in the past they can’t see the future. Don’t panic though, you’ll likely be long dead before fully autonomous transport rules the roads!
|Thread: Parallel Pliers|
Anyone using pliers to turn nuts or bolts should expect the worst! When I worked as a mechanic I was introduced to what was called a “Top Wrench”. Although I bought both sizes for use on track rods etc at which they excelled, they also worked very well on damaged nuts due to their self tightening action.
|Thread: Recommend a Small Parts Lathe for £2k.|
Single point threading on a machine without a thread cutting gearbox is not a problem for the home hobbyist with plenty of time on his hands. I can’t see it being very popular in a production environment though given the faff of looking up and changing gear wheels etc?
The 920 Lathe has a Norton style screw cutting gearbox.
It has belt change speed adjustment but there is enough money left in your budget to fit an inverter and three phase motor to give you a reliable variable speed lathe.
Or if you can up the budget a little:

|Thread: LPG heater- fumes|
I use a fan heater in my workshop, it soon heats up. I’m fortunate in that the floor is wood covered in painted ply so it’s a lot more comfortable than my past workshops with concrete floors.
|Thread: Brass Tarnishing|
Thanks for the replies folks, much appreciated. I already have some Renaissance Wax so I’ll give that a try. I also have a tube of Lanolin somewhere if that doesn’t work.
Is there anything that can be wiped onto brass tool parts to stop or reduce tarnishing. I suspect most options will be some kind of lacquer but I’m wondering if there are any oil based treatments that can be used instead.
|Thread: Parallel Pliers|
These look like a handy item.
There seem to be many different jaw types out there but due to the construction of the pliers it looks like it’s easy to make and fit your own custom jaws.
|Thread: New here but into clocks|
You are most welcome Derek, I believe there are a few clock makers on here.
|Thread: DRO on a Mill|
I find a basic digital scale on the quill indispensable for drilling. Some folks are keen to say it’s not very accurate but It’s been more than good enough for me.
|Thread: Metric micrometer what t buy?|
I’m with Dave, I don’t understand buying cheap Micrometers. I’ve got a Mitutoyo and a Moore & Wright 25mm which were both under £25 some years back. I’ve also got an old 1” Moore & Wright somewhere that cost me a tenner from a tool store that was closing down. I’ve got a 50mm Draper somewhere, no idea how much that was or how good it is but I’ve never used it.
|Thread: Knurling tool operation|
I’m waiting for the Chinese to start making these:
|Thread: Rake angle on Cutting Tools.....memory tips???|
Your reply was fine Ian. I too found the original question was a bit lacking in information but hopefully Neil has got it right and it will suffice.
There was a heated debate on another forum about rake angles etc. If you multiplied all the different “recommended” rake angles by the number of different tool shapes you would need 127 different tools as I remember. Much of the printed data about this is quite simply out of date and only really relevant if you are a production turner using one of the many carbon “tool” steels available 100 years ago. Bob has the right idea, just grind up some HSS and give it a try. It’s how I started. These days though, apart from “specials” I use a Tangential Tool or Insert tooling. Good luck.
|Thread: Cold Blue|
I’ve used Gun Blue liquids like Birchwood Casey with some success on small parts.
|Thread: Parting off tools for 102 lathe|
A quick google of your machine and I’d say you could use 2 or 3mm tips on it. They used 2mm tips where I used to work on M300’s, I never thought to ask why. I personally gave up using inserts for parting and went to T shape HSS blades and wouldn’t go back unless I had to part something particularly hard. These are the blades, I use the 1/2” ones:
These would obviously also work well in a rear tool post.
|Thread: Holding screw-end end-mills/slot-drills|
Yes, same here.
|Thread: Quick Machinists Jacks|
I might normally agree with you but I’ve already got 5 metres of 12mm threaded rod sitting in the shed. It will only take me a few minutes to put an M8 thread on a couple of bits. I only want two.
Sadly I don’t have a faceplate for my lathe so not an issue for me. Hopefully I’m out in the shed today to make a V block with a spigot to fit the hole I’ll be drilling in the hex bolts. Good idea about the adapter for use on 1-2-3 blocks but they have Imperial threads. Luckily I have some Stevenson's Metric Blocks tapped M8 so I can use those. I need to make some M12 - M8 adapters now ... And there I was thinking it was a quick and easy solution!
Edit: Yes thanks for the idea Clive.
