Wound the spring for my safety valve, put it together and tested it. It takes about 200 grams of pressure to move it, which is far too much. I will cut the spring down and try it again. . Luke, I've only just read your post, so I hope this isn't too late. Shortening an existing Coil Spring will make it Stiffer; so there is no point cutting it. You need thinner wire and/or more coils [not less] and/or a larger overall diameter to produce a softer spring. MichaelG. |

![]() 1181 forum posts 669 photos | Can confirm what MichaelG said. Shorter spring = harder spring I lowered my 105e Anglia by cutting 2ins off of the front springs, and that made a significant difference to the ride. Resorted to having a new standard set reset 2ins shorter. The cut springs worked a treat when I eventually converted the car and raced it at Kyalami.

27 forum posts | Hi Michael and Geoff, you're both quite right, I also have had a couple of cars lowered by cutting the springs, and the ride is much harder. This was all the rage in Queensland when the ink on my license was fresh, even though it wrecked the ride of the (street) car by any sensible standards. It was a cheap modification you could do to have your car stand out and look a bit different, hence the appeal at the time! I didn't explain fully what I was doing, but the reason I had to cut is so that I could have room to loosen the nuts holding the spring on, and therefore create a softer setting. The nuts were right at the end of the rod, and it took quite a bit of compression just to get them on. So although the spring in question is now shorter, it has (almost) the same length of travel, and therefore is much softer overall, and has room to adjust in both directions. Total force to move the valve is now about the 180g mark. Still a little high, but much closer to where it should be. I mistyped on my earlier post, it was originally 400g! The "textbook" figure is 100g. Regards Luke |

27 forum posts | Did a bit yesterday. Finished welding up my vacuum chamber (I think, it hasn't been tested yet). Separated and cleaned up the port faces from my previous post. Wired the mill computer power button up to the machine control panel so I don't have to climb underneath every time to turn it on and off. Replaced the BIOS battery as well, which needed doing. Generally tidied things up in the shed and found the floor again. Machines no longer covered in brass. Also planted some mushrooms! Today I'm going to see if I can get an order in for some bits to make a QCTP. Is cast iron a good choice for the main post? I am thinking a 3 inch cube of the stuff is the way to go for a Warco 1232. I'm planning on steel tool holders to go with it. Edited By Luke Graham on 25/10/2013 14:50:51 |

1058 forum posts 16 photos | Paul, I converted my BS0 to stepper control a while ago. I used an Oldham coupling to connect the motor to the head and it works flawlessly. I have been using a division master to control it but recently built one of Steve Wards indexing controllers, significantly cheaper than the DM and better facilities. CB. Gave the Boxford shaper a fresh coat of paint this week. P.S - don't for one minute think this thread is boring although maybe should be archived at the end of this year and a new one started for 2014. |

![]() 25215 forum posts 3105 photos 1 articles | Yes following the replys to my questions a week or so back the thread will be locked on 31st December and a new one started. What does make it boring is posts about non ME related stuff. If people are bored with it either don't read as Norman suggests or post something interesting and on topic.

75 forum posts 6 photos | What does make it boring is posts about non ME related stuff. JasonB Not everyone is a model engineer! Surely there is space on a forum like this for ideas outside strictly model engineering? And this website covers MEW as well as ME. It has been noted before, by at least two previous MEW editors among others, that quite a lot of people who take the mags are into engineering but not specifically the making of engineering models. Well, if I have to report in on today's activity in order to qualify, I spent the day machining tongue & groove joints on boards for my new (wooden) garage doors. Jim

![]() 25215 forum posts 3105 photos 1 articles | I was refering to things like painting the spare bedroom, visiting the mother in law, taking the dog to the vets, etc As per Springboks post. I'm quiet happy for it to include anything engineering/ home workshop related. The whole reason I started the thread was to get people to say what they had been upto in their sheds/workshops, that is why this thread is in the "Work in Progress and completed projects section. If you read the second paragraph of my opening post you will see I wanted it to be a place where people could show what they had been making. J Edited By JasonB on 25/10/2013 20:46:55 |

![]() 2314 forum posts 139 photos | Jason Well the thread title is "What did you do today? So that really could be anything. In my view the thread is predominately " workshop related" so the odd " took the dog for a walk" is legitimate and, in truth, doesn't bother me much. I guess you could name your new thread " What did you do in your Workshop today" which might produce more focused contributions but there can be no assurance of that other than extreme moderation or banning " off topic" posters. ( I would be quite pleased to hear of your day unblocking the sink or scrabbling around fitting a new bog seat as that tends to by my experience of life whilst your superb daily efforts leave me open mouthed in admiration . It might be comforting to know that you too suffer from time to time!) A days shopping with my wife tomorrow - but hey - I will enjoy that too. Regards Norman |

![]() 4318 forum posts 291 photos 1 articles | This thread is what it has become, not what it was intended to be. Such is the way of these things. Personally, I appreciate getting to know a little more of the day to day of our contributors. Not least it helps to understand why A is knowledgeable about X or why B can take approach Y. It's also one of the 'friendliest' long running threads and it would be a dire shame if it descended into the same mire as as some others. Neil |
