Looking at the links there is no sign of a plug of any type. I assume Oldiron saw the voltage printed on it and gambled with the odds of success being fair that the 20A input was left from another machine rather than an appalling badly designed machine. |

As it's all coming apart. Use wood to jam the bull gear and a bar across the jaws to loosen the chuck. |

You need the tool tip width to be greater than the 'thread' that you can currently producing. Slow down your cross slide winding hand or use a broader tool tip. Bolt steel is extra stringy stuff and gives a torn finish unless tools are very sharp. |

Not much, they aren't very useful. This one is what I have as well - only with less rust, MT1 centre they never have a makers name on them, but Jones & Shipman has been linked to them. |
Thread: Anyone got a Rhubarb clump still going? |

Can't grow it anymore, though moving the plants to the kids gardens they grow fine. Must be like rose sickness for rhubarb. |

Hi Maurice, You may be able to apply for a single machine permit instead of a gaming machine technical operating licence if you:
" Like many laws enforcement may be low, but like speeding not getting caught does not make it legal. Robert G8RPI. I don't know if there are any actual qualified lawyers on this site who could give an informed opinion. 248 No prize(1)A person does not commit an offence under section 37 or 242 if— (a)he makes a gaming machine available for use by an individual, and (b)the individual does not, by using the machine, acquire an opportunity to win a prize. (2)The Secretary of State may make regulations creating exceptions from the offence under section 243 in connection with machines which, by virtue of their nature or any other specified matter, are not designed or expected to be used to provide an opportunity to win a prize. The 'no prize' requirement probably explains why your money goes straight through, no doubt the reels still spin. |

So from Journeyman's link it could be 10A to 140 or maybe 35A to 145. This is how the specs get screwed up with cut and paste and how your Thai advert mentions TIG when it clearly isn't. Oldiron has clearly used his so we know the design works. Just make sure you can get the copper tips for the gun where you are as it doesn't have a Euro plug in gun. You will get a burn-back that wont come out of the tip at some time. Don't buy the cheapest wire you can find it won't work very well. |

It goes back in time too. There was a day when there were tens of thousands of horses trotting round cites belching out their pollution and not enough old men with buckets and shovels growing rhubarb. |

Can anyone help? I have an old one arm bandit machine which has been converted to accept the new 1p coin, when i put these coins in they fall straight through the macine, how can this be fixed? Something wrong with the conversion I would imagine. There should be a gate to slow down the coin and divert it into the coin collection box. regards The coin mech should be removable and still work without the rest of the machine so you should be able to see whats going wrong. If it's a one penny bandit have you tried a 2 pence piece? |

This might be me living in sheffield too long... but I have my own linguistic bugbear. "Knifemaker" and "Bladesmith"... NO!, Bad american hobbyists and pretentious blacksmithing youtubers who don't want to make anything big or difficult, Bad! The term for a person who makes knives and bladed instruments is a "Cutler", and I'll die on that lexical / dictional hill if I have to*. *Hope it doesn't come to that though, it's only words! What makes you think Americans would what a Cutler is? Or Cutlery? Or what a table knife is for other than cutting things up. |

Hi MichaelG, that is interesting, and although I can't recall ever seeing that house, I've certainly been close to the location when arriving on a train a few times back in the late 50s / early 60s with my parents and siblings when we went on our summer holidays to my mothers parents who lived about half a mile away, on London Road South. Had many happy holidays on Lowestoft beach, the boating lake and the miniature railway with a steam locomotive, even saw Leslie Crowther once outside Claremont Pier. One or two photos of the Miniature Railway in Lowestoft Regards Nick. P.S. I've just looked on Google Maps street view, and you can see the Banksy artwork with the skip still in place. We did walk down that road beside the railway once to a long footbridge that used to go over the railway to the road on the other side. Edited By Nicholas Farr on 12/01/2023 09:05:15 Likewise, my great aunt had 'Seascape' on Marine Parade (the name survived till recently) I used to watch that train from her window. I watched the parts for the Sizewell reactor trundle past from the docks. The big grey crane that used to stand by the bridge was built to unload them. There used to be a dairy at the dogleg of the Parade where you could watch the bottling process through the windows it's now Potblack. Edited By Dave Halford on 12/01/2023 11:35:17 |

How do people protect their tools from corrosion in a non insulated workshop ? I used to have my lathe and mill at my work and never had a problem. Now with this cold weather, my mill bed turned brown overnight ? I’ve now covered them in BBQ covers, but does anyone have any other suggestions ? It all largely depends on your workshop construction. Single brick or wooden shed, the recent rain will get through the walls and condense on your colder machines covered or not. Concrete floor without damp proofing the same thing happens and in this case the plastic covers can make it worse. Chainsaw oil has a sticky nature and is not easily displaced by water |

Competent person? That would be covered here so it seems to be not so woolly after all. Says the man who was a competent person to fit a 13A plug and had a card to prove it. Yes really! With RFI you may get trouble if the VFD spec says apply RFI controls and you don't and someone complains. If it's not mentioned then you can shrug I guess. There was an RFI issue at Heathrow due to someone unplugging a live CATV feed in a Brentford flat and screwing up aircraft on approach flying straight down the Brentford main drag, as they do.

Thread: Changing the motor in Drill press |

Posted by Ian P on 10/01/2023 10:13:22:
There have been a few mentions in this thread regarding the unsuitability of a drilling machine for milling purposes. The OP made no mention of wanting to use the drill for milling purposes, he just asked a straightforward question about changing a motor. I think that all that is happening now is that the OP will get more and more confused. Ian P Indeed The op states WOOD. Admittedly it's not often we get someone from the dark side posting, but even I know that a basic milling machine for wood is called a router and commonly spins a lot faster than our milling cutters. Andrew, On picking your belt speed try to keep the motor speed fairly close to the plated 50hz speed as the motor fan is not very effective at significantly lower speeds. You may also need more power for large forstner type bits or hole saws if you. |
Thread: ME Beam engine flywheel |
08/01/2023 11:19:52 |
If you can't get the boss centred under the the chuck of an SX1 to bore it then machining the rim is a little academic. If it does mounting the flywheel for side milling the rim on either a rotary table if you have one or make a plate with a pivot to suit the boss and a large lever to control the feed. The last suggestion is last resort and a bit fraught with danger and possibly too far outside the box. Don't climb mill by mistake, the flywheel will have lots of leverage to overload a small table.

There seems to be some porky's going on. Just been on Vevor .com website. This is cut & paste through notepad direct from there site. Steve, There's more than 40 of them, which version is yours? Given you can't trust the paint colours. Come to that one of them shows the heater outlet inches away from a sleeping child in a car seat and I don't believe for one minute anyone would take that sales pitch seriously. You have to click the right photo arrow once to see that one Edited By Dave Halford on 05/01/2023 17:00:12 Hi Dave. The actual burner seems to be in only 2 sizes. The small bodied 2Kw & the badged 5-8KWSome as you will have seen are self contained with the fuel tank sat on top of the burner unit on a tin shelf. I have the open separate one. It is not a Vevor but basically they are much the same. A copy of an Eberspacher or webasto. It is a bit ironic the the Vevor pdf file says not suitable for buildings & then on there website it says they are. Not sure if there are some sort of get out clause in there. Some of the sellers show flames belching out of the front of them Others pics like the one you describe. What i do find a shame is that basically talking of buying inferior Chinese products , when most or a large proportion of Forum members own Chinese mills & lathes & drill presses &. You see the point. Most electrical items are now produced there. Even some of the Branded items we think are worth the extra for are not made here any more. The UK has become a Distribution centre & commerce. Steve. Edited By Steviegtr on 05/01/2023 17:19:05 Steve, The website is just sales BS, like the link in my post. The PDF is a little more careful. Even in the UK you can apparently legally use a business sales 'puff' which is kinda nearly true. Fanciful claims just put me off so I wouldn't buy it. I use cheap CCGT inserts, a bit more fragile than real ones, but a ratio of nearly 4:1 on cost makes them worth it. I've also bought stuff from ME shows when I can hold and look at it. All the large far east large tools that I have bought have been to some degree junk
So I only buy pocket money stuff now and your heater is way too expensive to gamble on. |

That's a bigun, I've got 2 side by side cones on my Rockwell Delta lathe for 1HP. That might need matched belts all round and ordinary ones are £50 each |
