Thread: IC engine tractor conversion query
31/07/2019 15:46:44

I think it's fair to remind ourselves that whilst the petrol engine runs at full speed, it doesn't run at full load much of the time.

Thread: How to remove four jaw chuck screws?
13/06/2018 21:10:38

I'm thinking that those circular plugs at the rear of the chuck have some sort of forked section which locates in a groove in the screw holding the screw from moving along its axis. Maybe tap the plugs to take a length of screwed rod and then with a nut washer and a short length of pipe slowly extract the plug.

Thread: Cheap software
14/06/2017 20:29:00

You must know full well that it is of course pirated software, a quick check online shows that Photoshop CS3 is nearly £600 on Amazon. If the programme on the disc actually installs and runs it is very likely to include your special free gift, namely a trojan keylogger that will send home to daddy every so often all your passwords and logins for online banking , shopping and even the model engineers forum. I have a copy of Lexia software to run diagnostics on Citroens, it sends my anti virus mad even trying to install it, so I run it on a lap top that never goes anywhere near the internet.

Thread: CO2 Mig welding bottle

If Its Bass bottle just exchange it at your local brewery suppliers. Or fiendly pub landlord. Pub bottles are used to pressurise ber, there are thousands of them on circulation at licenced premises. Nobody seems to worry about them too much.

Thread: Internet scam?
30/05/2017 14:13:38

At my work I receive these calls, sometimes more often than daily either a vindoos problem or to do with my electricity contract. I've now started saying that the business has closed and that they have come through to the security ofice and that the business has folded owing thousands and would they like to leave me their number so the police can get in touch with them , CLick. Sometimes I tell them that ( my name ) is no longer working for the company and they need to speak to Mr Pramshed, and they dutifully write it down, basically wind them up as long as possible . If you let them they will take you for every penny. Action fraud reports losses of £691,000 in 2015 .

Thread: Air in the workshop
30/05/2017 14:03:12

Like it or not 25 years ago I plumbed out my garage using Hep2o piping, which was brown and called Acorn when I did it. Since then I have had zero leaks and can't fault it in any way. The system runs at about 90-110 psi and I use snap on air fittings. I may change over to euro fitting as these have a larger aperture for the same size of fitting.

Leaf spring off an old car , next to nothing at a scrap yard.

Thread: Derby Industrial Museum
17/05/2017 09:49:46

One could spend a long time looking round N Wales for the MoIF, it is about 8 miles north of Cardigan. The issue with the signage may well be a result of local planners , rather than any attempt by Paul and Hazel to hide........Private Eye has had quite a lot to say about planning policy in the area.

Thread: Cyanoacrylate and Quicklime
13/05/2017 23:30:35

It's been available in the motor trade for some years , but I expect the price will have come down somewhat now. I believe the filler powder may well contain a catalyst for the superglue. As other have said it forms a very hard and quick repair on may substrates.

Thread: Can you identify this engine?
18/04/2017 10:41:54

My advice would be to take the mag off and leave it somwhere warm for a week to dry the insulation out. Old magneto insulation absorbs water from the surroundings and then can go short after a little running . When you have a decent spark . Then try the engine with a whiff of easy start. If you have a spark it will at least go pop.

Guys , it's just been left out in the rain for a while. Water the universal solvent.

Thread: Spline gauge.
02/04/2017 23:30:07

I did a bit of development work for a company that made replacement rear axle shafts for quad bikes, just like you want to do . The splines we had on the shafts were a 90 degree angle and were rolled onto the shaft originally. we were able to cut the splines by using a dividing head and a simple end mill along with a bit of relatively simple maths.

Thread: Lathe line boring
12/03/2017 13:55:45

I'm sure I am pointing out something that will be obvious to you, but you should plan to machine the base first of all to a finished dimension working from the nominal centreline of the bore. Then you have a nice flat face to clamp the workpiece down for other machining. That face  will then be the datum face for all the other dimensions. Normally there is plenty of meat on castings so it should not be too much of a problem. .

Thread: Help with a thread mistake
23/02/2017 12:25:39

Well the easiest way would be to buy a helicoil kit and re -do the thread the correct size. JB weld won't be up to the job ( or jb perhaps) . A lot of motorcycle heads get helicoiled  when the threads gall or strip. A helicoil is a 'stronger job' anyway. However as we are on the Model engineers Forum I have no doubt that suggestions will abound around making a threaded Titanium bush, or some other more complicated suggestion followed by 11 pages of posts about the appropriate tapping size, or the correct grade of material for the job. Helicoil kits are available cheaply online. Inserts can be shortened if you are careful or different lengths are available. Once the plug is in no one but you will know it is there.....

Thread: Tuning
07/02/2017 18:27:42

In responce to packmule, some amatuer tuning is still possible . There was a young bloke near here who had a moped with a watercooled Minarelli 50cc engine . I was boring him with tales of how we used to tune old Bantams and Villiers engines by taking a couple of mm off the top of the exhaust port, cleaning up any burrs etc in the inlet and so on. We also looked and found a washer welded in the top of the exhaust pipe with about a 10mm hole in it when it was in place.

So first the washer came out and the next time I saw this young bloke he got me to follow his moped in my car to check the speed. I clocked him at 68mph in my car for about half a mile . Question , how long did the engine run before the piston melted?

6 years on he is a very well qualified motor engineer working as a responsible MOT tester, having learned a lot of lessons the hardest and probably best way.

Sadly this mind set of 'best in the world' is still alive and kicking in the UK. Only last night I was watching the BBC news. Welsh farmers produce the 'best lamb in the world' now that are worried that if we do a trade deal with NZ then Kiwi lamb will come in and undercut them . There are currently quotas that limit the amount of meat the Kiwis can sell here. When we are out of the EU these won't apply of course. It's the same model that sounded the death knell for our industries and it really sad, but if we can't compete on a level playing field then in the long term it's not going to end well is it?

Thread: Cam Calculations
27/01/2017 00:41:47

Following on from Tims comments, if I may , the shape of the cam follower is also vitally important , flat or radiused and the radius of the follower all affect the rate of opening( and closing), but not the overall lift. If I can remember a flat cam follower will give an aggressive rate of opening wheras a radiused follower is more gentle.

Thread: A Triumph for BSA
24/01/2017 17:18:56

BSA took over Triumph in 1951 and although similar in many respects to the BSAC15 design , if somewhat smaller, the Tiger cub was indeed a Triumph design , one can tell as it had a silly little plunger oil pump, unlike the BSA's which tended to have gear pumps.Towards the end of production there was a Bantam Cub, which was indeed a Cub engine in a Bantam frame. whether it badged BSA or riumph I don't know off hand.

Thread: Ebayer refused to sell to me - on their avoid list
24/01/2017 12:48:44

I f I had sold something in good faith on Ebay and someone left me negative feedback I would be extremely dissappointed . Every seller always says something like ,' If you have a problem with an itenm , contact us first before leaving negative feedback'. you didn't do this and so left the seller negative feedback without giving him the option of resolving the issue. This is effectively vindictive, like getting in a fight before letting the bloke who spilt your pint apologise and offer to buy you another one.

There is a reason for feedback, if there are 50 sellers of an item, fuel hose , widgets or whatever, then not every seller can be at the top of the first page obviously. The sellers with good feedback get to be at the top of the first page and sellers with worse feedback end up on page 9 where no one ever sees their item. Negative feedback should only be left really for Rip offs or other serious reasons , not because you don't like an item or it's not quite what you expected. Your feedback could have really serious effects on the seller.

If I was selling coily airlines with brass ends and one was 8mm dia and one was 10mm dia , I would describe them as such rather than cut one in half and say 'well it has a 5.9mm bore , but its only 5.5mm where it passes through the brass fitting'. No, there it is on the shelf one is yellow and 8mm and one is blue and 10mm and that is what you get.

It's hardly any wonder he doesn't want to have anything to do with you is it?

Thread: Freight / Import duties.
16/01/2017 14:41:38

As I mentioned in a previous post I rang up and asked HMRC about import duty and they were most helpful. Why not ring them up and ask if there is any way of avoiding the collection fee, possibly by registering with HMRC as an importer and having a number. I'm sure Curries don't have lorries turning up at their warehouse with the driver going ' Ere mate , lorry load of tellies ere for you mate, oh and wheres the boss ' cos theres a £10, 000 bill from customs before you can offload 'em.' So there may be a way of formalising things. I know I bought some thing from the USA and I know I paid the customs in advance and paid a little bit extra so as not to have it submitted to HMRC upon arrival in the UK. It seemed to me well worth the effort.
