Terrific. Is it large? Terror inducing? Or is it really good? |
Thread: New series by Tim Hunkin |
21/04/2022 20:09:24 |
I remember being enthralled by his stuff when I was younger, so a couple of years ago I sent him a message thanking him for making a series which still sticks with me now. He was gracious enough to reply, and as you can imagine was polite, erudite and self-effacing. Lovely chap. |
Thread: Myford ml7. Longbed for under £200 |
16/04/2022 21:47:45 |
I'm sure its useful to someone; the ways might be in good order, its hard to tell. |
Thread: cut-off |
16/04/2022 21:46:20 |
Donkey saws seem to have gone out of fashion; I think I'm going to try to find a reasonably priced one of those. Less worry than a bandsaw. |

This is superb. |
Thread: cutting pyrex tube to length |
16/04/2022 17:59:32 |
I've had a suprising amount of success by just sharpening an HSS cutting tool to a knife edge point and turning the glass in the lathe. I wrap the tube in tape to protect it from the jaws, but a better way would be some sort of soft jaws as it can be a trial to get it concentric this way. I cut the end off of a pyrex test tube this way, but usually I cut normal glass. You just gently introduce the cutting tool at a 90 degree angle and the glass cuts a vee which you can then tap gently to break once its deep enough. Playing a flame over the cut edge works for normal glass I think with pyrex you would have to use an abrasive grit paper to get the end sweet.

Thread: ml7 tri leva cross slide screw ? |
15/04/2022 16:02:05 |
Quite a bit of backlash isn't unusual, but its probably not the nut. As others have done, on my ML7 I bored out the hole that the shaft goes into and fitted a 1/4 x 3/8 x 1/8 sealed bearing, with an NTA411 bearing either side (a needle roller bearing with washers, two of, part number NTA411). The removed a vast quantity of the backlash. |

You had enough spare minutes to kvetch a response... |
Thread: silly question about oil drip feeder ... |
11/04/2022 20:45:18 |
I was told that with the myford oilers you should be just getting bored waiting for the next drip and then there it goes! Mine tremendously over oil. I usually am on the lathe long enough in one go for the oilers to almost empty. As for the thread cutting, there are charts which will help you out on google that you can print off for the workshop wall. Don't forget the material you are cutting will have a bearing on things too. |
Thread: Fitting a 5 micron DRO to Myford ML7 |

What are you making that demands that accuracy?! |
Thread: Making gears in the lathe |
11/04/2022 16:11:23 |
I tend to only cut about three different thread pitches. So you don't waste any effort, do you need these gears? |
Thread: Set screws replacing rivets |
11/04/2022 16:06:24 |
Small size rivetting is very effective and quite easy even for someone with ten thumbs like me. It's your locomotive, do as you wish. The only people you need to please when building are you and the boiler inspector (And he won't give a damn about the hornblocks!). I would probably think rivetting is easier rather than faffing about countersinking, loctiting etc. |
Thread: rivet snaps |
10/04/2022 21:49:59 |
Most of my rivet snaps have a side ground down for clearance with previous tasks. I don't bother to do the full circumference. |
Thread: Central Heating Control |
10/04/2022 15:00:32 |
My Grandfather was the foreman of the Boiler House at Boscombe Down which supplied superheated steam to heat exchangers fitted to all the other buildings of the site. It was an interesting system, but I suspect it wasn't very efficient. Oddities included the Weighbridge hangar with an air curtain system coming up from the floor to try to retain heat when the doors were open, and the heat exchanger connected to a merlin engine radiator/heat exhanger to warm fuel up for tropical testing. Don't fancy being near that when its all toasty.
Back on topic I'm finding my house heating far more efficient now I'm heating specific areas rather than all of it. It's a tall and narrow house on three stories so all the heat goes to the top. I've suggested using a fan and ducting to bring the hot air back to the bottom but my wife really doesn't like the idea of my experimental duct-work...

I've used white vinegar in the past with good results. |
Thread: Modern boiler construction methods for the model engineer |
08/04/2022 17:11:38 |
I love this application of modern techniques to our hobby. Brings it into the current age whilst maintaining the spirit of ME. I think I'm a data nerd. When I was younger my cars all had as many gauges as there were things to measure... |

Trouble with ebay is it's a market-place, not a single seller..
..and I'm always astonished at how many people forget that. It's like writing off an entire town's shopping precinct because you got stiffed once at the Sunday market.

I was having a brain fart. I was thinking I'd used it incorrectly as a contraction (as in "Keith Appleton is"
