Ah, so I'm guessing Weller is American? It's funny, whilst I was born into a mostly imperial measurement world and was then merged into metric, one of the few things I don't ever think I ever used is Fahrenheit scale (maybe early tropical fish stuff)? I guess that's because it's scale doesn't relate to anything tangible to me, like the freezing and boiling points of water etc? >6=600, 7=700, 8=800. <conversion> ah, 6=315, 7=370 and 8=425 DegC (although I agree those numbers don't have such a ring to them and would be difficult to mark on a tip). ;-) >Many US suppliers such as Mouser.com and >Digikey.com stock parts for these older Weller products.

I've just fired my iron up with the new barrel and tinned the ends of a couple of bits of stranded copper cable with my 6 tip and it seemed to do so very easily. Maybe a 7 would be required if using unleaded solder (which I'm not)? I have a couple of 7's on their way so I can see how they compare on my iron. Cheers, T i m |

Ah, and that explains the 'waisting' I saw on my existing (and only) tip. Good tip. ;-) Cheers, T i m [1] Just looking up Curie Point science again it explains what was happening the other day. When the iron was cold and the permanent magnetic field was high in the tip it held itself into the element (the end of the barrel was worn oversize and didn't retain the tip) until it warmed up and then would fall out, just as it was up to temperature. ;-) |

The mechanical switch that is operated by the magnet can get stuck/seized, meaning that the iron gets much hotter than it should regardless of which tip is in it. It's entirely possible that a properly working iron with a number 6 tip is hot enough for what you are doing, but if you find that it is too hot then perhaps the switch is stuck. Chris |

Ok, that's good. Maybe they made more different sorts than the ones that I have. I'm pleased that it worked. I'm curious whether your new barrel is larger in diameter than your old one. > The other question is do we generally put any sort of thermal / anti > seize paste on these things please, or would pretty well anything > simply burn off? I guess you could use copper grease or aluminium grease and though the grease part would probably burn out and smell and make a mess, the metal particles ought to remain. I doubt it is necessary and I've never used anything like that on a soldering iron. The only ones that I have had get really stuck were Antex ones. I think that if you just disassemble it occasionally either to change tips or just to inspect it, that should prevent it getting seized up (and if it does you would catch it before it is impossible to remove). |

I'm ahead of you there. When I was still at BT (so 40 yeas ago now!) I modded my PU-1D base with a front mounted red LED that goes on when the element is on (and it's still working). ;-) So, if it was stuck on (or off) I'd soon see it in the 'activity' LED (and have in the past when a small tap on the element seems to cure it, typically stuck off). Your good point is noted though. ;-) Cheers, T i m p.s. JOOI ... I've just timed the iron heating from cold (20 DegC ambient) to the 600 DegF (315 C) tipped iron heating till the LED goes off and it was 55 seconds. |

With a selected collection of zeners and diodes it is possible to put a droppered LED, across the AC supply line. Unfortunately LED off when iron is on (supply loaded), but at least , it shows the switch is not stuck on. |

That's how it was designed but I was reminded when talking to Chris that I modified mine 40 years ago with a red LED in the front that comes on when the element is drawing current. >droppered LED, across the AC supply line. >Unfortunately LED off when iron is on (supply loaded), but at least , it >shows the switch is not stuck on. Ah, my LED definitely comes on when the heated element comes on but I can't remember how I got there? I do know I built, assembled and fitted it and it could have been co-designed by one of my co-workers at BT at the time. Cheers, T i m |

I'm still in fairly good shape so hopefully that won't be a requirement for me. However, I'm lazy and would probably buy an electric start conversion if there were such a thing. I've often thought a removable ratcheting hand crank start, like in my former Land Rover Series IIa might be easier than a string pull. I live in an overgrown redwood and douglas fir forest. However, my days of dropping trees are in the distant past. These days it's construction scrap, clearing smaller trees, brush clearing, and trimming oversized firewood. I probably spend more time repairing other people's saws than using my own. Sigh. I big branch came down in the last storm. While cleaning off the roof today, I noticed it had bashed in the 2x6 T&G roof and split one board. Tomorrow will be dedicated to gluing the mess back together. Yet another normal day in the deep dark forest. <http://802.11junk.com/jeffl/pics/home/> -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
Jeff Liebermann <jeffl@cruzio.com>: Sep 16 08:47PM -0700 >How do you tell when the bar lube is blocked? Remove the bar and chain. Chain oil comes out of a hole that mates with a corresponding hole in the bar that only goes half way through the bar (i.e. the hole is only on one side of the bar). Run the saw without the bar, chain, or cover, for about 60 seconds. You should see oil slowly dripping or exiting as a small mist out of the hole in the body. If nothing comes out, it's clogged further upstream or the pump is trashed. Lots of YouTube videos on testing and fixing chainsaw oilers: <https://www.youtube.com/results?search_query=chainsaw+oiler> More common is that the oil hole in the bar is clogged with a mixture of oil, dirt, and sawdust. This would probably be a good time to clean out the bar groove, dress the bar, remove the sharp edges, flatten any dings, lube the sprocket, etc. <https://www.google.com/search?q=chainsaw+bar+maintenance> No need for the specialized tools. Just a scraper that fits in the groove, hand file, and trisquare. If the lack of oil has caused the bottom of the side plates on the chain to wear and the edges of the bar to mushroom into sharp edges, you may need to have the bar squared and the groove deepened. Also, it helps to flip over the bar to extend the wear life. Most people don't like the way the saw looks with the manufacturers name inverted on the bar, but that's a small price to pay for extending the life of the bar. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I assume the noise is also gone. I'm rather surprised you didn't find any magnetized solenoids, because every one had the problem to some degree. However, if you fix the pads so that there's no metal-on-metal when the solenoid closes, the effect of the residual magnetism is negligible. >Thank you.
