|Thread: Lifetime Guarantee ( Ford)|
I had a new Citroen GS back in 1988. It was a great car except for rust! At the end of the first year it had holes on the doors where the window frames met them. A few years later they started galvanising them and cured the problem.
|Thread: Having PCB's made|
Making a PCB is not so difficult. I had to do it 20 years ago as a uni project. Just do it yourself!
|Thread: Beyond my skill level!|
I'm a bit sketchy on the differential effect when using separate motors on either side with the motors in series, but as the inside motor on a turn is slowed down the outside motor gets more electrical "bits" and speeds up. I know this from practical experience but don't understand how it works.

"Norman; let's hope your pal can be big enough to accept you intention & you can get back to having a bevvy, or two together again... ... wry smile?"
George, Mechman48, not yet.
I detest emoticons and don't use them. I recently fell out big time with a long standing friend as he did not realise that what I said was a joke and he took it as a personal criticism, the damage is still not repaired. It can sometimes be difficult to demonstrate humour in a quickly written message. Maybe I should start to use them?(would you say that that is a wry smile?)

|Thread: Tank restoration|
I was surprised, when you titled your post "tank restoration" I was thinking Water tank? Army tank? I was not expecting petrol tank.
I can't offer any advice, I used to own a BSA A10 and the tank cracked around the outlet, I couldn't find anyone to repair it and had to replace it with a cosmetically inferior one. Happy days, I paid £12 for the bike and sold it for £70.
|Thread: Slideway protection|
I use a piece of steel sheet held on with magnets. It does stop me getting too close to the chuck but is quick to remove.
|Thread: Machining Titanium on a Hobby Lathe. Is it a good idea?|
Ignorance is bliss! I have had two experiences with titanium. I asked a local engineering company who specialise in exotic metals to roll a cylinder for the smokebox of the loco that I was building. I gave them the choice of brass or stainless steel. When I collected it they told me that they had neither of those metals in 1/8" so had used titanium as that was all they had. In later years I realised that it was not titanium as it was very soft and sticky to cut and tap. I have no idea what it was. Recently I used some titanium sheet to make some camera parts (it's all I had at the correct size). I cut it with a cutting disc on a Dremel. If I had seen the video of it burning I would have thought twice about using it. Anyway, all was well, but it does tend to crack when you bend it.
|Thread: Lathe for sale|
I deliberately did not comment on its suitability for anything ( far be it for me to comment on other peoples ability), although I do think that it has limited use. The main thing that I noticed was how thick the paint is! (look at picture 7)

|Thread: Fireproof Overalls|
Jack the ripper was never caught!
|Thread: Lathe for sale|
I saw this homemade lathe on Ebay. The owner certainly didn't skimp on the paint!
Ebay item no.172506289779
|Thread: Paypal scam|
I received an email a couple of years ago purporting to be from Paypal saying that my account had been suspended. Being the disbelieving sort I did not follow the link and logged in to Paypal my usual way and found that all was fine. I try to keep my disbelief in gear at all times. Another time I had a phone call from someone saying that they were phoning regarding my motor insurance. I did not believe him and told him to write to me. He did, and had cancelled my insurance!
|Thread: Copper rivets|
GLR Kennions have the 3/64ths in copper and steel. For the 1/32nd rivets couldn't you just get some 1/32 copper wire and form your own heads?
|Thread: 'Re-purposing' old hand drills|
I had a Stanley hand drill from the late sixties that broke (I can't remember the problem). I mounted the chuck on the handle, it made a very useful holder for things like countersinks for deburring.
|Thread: Aldi Angle Grinder sparking - is there anything I can do?|
Keep your receipts. B&Q have a two year guarantee, I'm not sure about Aldi and Lidl but it will be at least one year.
|Thread: Electronic mouse trap|
I had rats in my house. I bought a large bag of poison pellets. Set a few where I had seen a rat and put the bag away in a cupboard. Next morning I found that the rat had chewed its way into the bag and stolen most of the poison. I didn't see any more of them after that.
|Thread: Cheap but decent Mini Tape Measure|
I used to be a teacher of design and technology. I tried to get the kids to use millimetres, it was impossible. Every other department in the school used centimetres. I tried to persuade the other teachers that they should use SI units (which does not include CMs) what a waste of my time! I've given up. It was easier with inches, at least we were all singing from the same hymn sheet.
It no longer matters to me. I am retired.
|Thread: Best way to cut stock to size|
Despite all the arguments against angle grinders they are very convenient and cheap. I have used the cheapest from B&Q and yes, they are not great quality but at £20 they are great value. I bought one and used it for six months and it burnt out. I had kept the receipt so I took it back and was given a replacement. That too burnt out after a few more months. I took that back and as there were none in stock I was given a refund. So what is there to complain about? One years free use of an angle grinder. That seems good value to me.
Not cutting but grinding. For aluminium, the discs designed for stone work without clogging.
|Thread: Take a look?|
It all goes back to where you accept that someone has built their own loco or traction engine. Laser cut frames, spokes for traction engine wheels, made their own castings, dug their own ore. It all depends on where they want to start. I know what suits me, building from a ready machined kit is not engineering but some people get enjoyment from it. Do what suits you.
