Hi, In my Reader's Digest Universal Dictionary page 434; di-elec-tric (di-i-lektrik) n. A nonconductor of electricity; especially, a subtance with electrical conductivityof less than a millionth (10-6) of a siemens. [DI(A)- (through)  + ELECTRIC.]
--di-e-lec-tric adj. --die-lect-tri-cal-ly adv.
 
page 430 di-a-lec-tic (di-e-lektik) n. 1 the art of arriving at the truth by exposing the contradictions in an opponent's argument or beliefs and overcoming them; especially, the Socratic method of question and answer to elicit the truth. 2 blar, blar , blar........ more about truths ect.
 
PS. the pronunciations in the brackets are not exact as they have got some of those funny little marks and wrong way round letters.
 
Hope this all makes sense.  Regards Nick.

I hear what you are saying John.

Hi, I have allways had a keen interest in electronics. I have bult many electronic PCB's even ectching the booards myself. However I don't think electronics should encroach into Model Engineering into any great extent. There are other publications for that interest. (just my opinion)
Regards Nick.

Hi, strange how you read the word thats supposed to be there, although it is spelt wrong. Couldn't see it till I got to Andrew's post.

Thread: Dangerous Practices
15/09/2010 18:51:00
"Even with the chuck tightened by gorilla, application of sufficient side force would shift the work piece in the chuck." by J A Harvey-Smith.
 
Didn't read in the text; plough into it and get this bit done and out of the way. I think if you were to apply the amout of force required to shift the set up in the photos, you shouldn't even be using a lathe. The use of the tailstock centre support is mentioned and shown. This is said for "added security" which makes it even less likely to shift sideways even if your cut was a bit to heavy.
      Still not covenced that it is a dangerous practice.
Regards Nick.

Still no explination why one believes its a dangerous practice then.
Regards Nick.

Wel David, at least they may get the point.

Thread: What is the truth about "Tich"and "Minnie"?
13/09/2010 20:23:41
Hi, I to have castings for Tich, and maybe one day soon, or maybe later I will get round to start building it. I will say that although I have nothing against clubs, I have no interest in joining one. I prefer to be totally independant and produce what I like when I like or maybe never. Its the interest in machines and mechanisams and tinkering about  that I find rewarding.
Regards Nick.
Thread: Dangerous Practices
12/09/2010 23:04:40
Hi, If the method of workholding in the said photos is dangerous, then explanation should be made as to why. I myself have used this method many times during my fitting in industry when sizeing keys for shafts. I have never had a problem with this method, as has been said caution, vigalence and common sense when chucking anything before swinging the piece to be turned.
Regards Nick.
Thread: Another 'What Mill' Question
11/09/2010 17:33:18
Hi John, have you tried heating your drill with the stuck on sleeve, as it may be just that. Stuck on with Loctite, and if is 638 you won't move it without heating or cutting it of.
Regards Nick.
Thread: Chester's CQ2365/ 920
10/09/2010 09:41:20
Hi James, even if the backplate was running true the correct way round, it is unlikely to run true back to front as they don't have a true registrar on the front to fit the spindle nose. Regards Nick,
Thread: BMS angle not 90 deg
07/09/2010 23:59:14
Hi, Ihave to agree with Andrew, BMS stands for bright mild steel which is cold processed in its final stage, it is normally fairly sqauare, but rarely exact. It would be quite pricey to use in general fabrication. Black, or hot rolled as it actually is, is used for fabrication perposes and very seldom square or truely flat. Regards Nick.

Thread: wheels and loctite
31/08/2010 00:26:28
Hi, 638 is a high strength with a diametrical clearance of up to 0.25 mm, 603 is the same high strength but with a clearance only up to 0.1mm. Both these reach thier handling strength in only 8 minutes so you must be sure that you get your wheels in the correct alinment without to much hanging around. Once this stuff is set you will have to heat the whole joint to 250 C if you need to remove it. 641 and 668 are both medium strengths and are for clearances of up to 0.1mm and 0.15mm respectivly and have a handling strength in 30 minutes and are more easily dismantelled if the need arises.
Hope this helps.
 
Regards Nick.

Hi, maybe the War Office missinterpreted the information when they heard about General Feild Marshal Walter Model's army in 1944 and though they had to scale down thier attack.

P.S. 'ope me English is understandable.
Thread: Doris LMS Black 5 by LBSC

Hi, virtually all asbestos and even second hand asbestos was banned from use in the UK by 2000. It still exists in buildings and all sorts of places. It dose not have to be removed unless in is in a poor condition. A lot of the dangerous types of asbestos can only be removed by lienced firms, other types sould only be removed after you have had traning to do so. for more info go to www.direct.gov.uk and type asbestos in the search box at the top. I would not recomend using any asbestos even for private use. If any newly built models are put in the public domain anywhere that contain asbestos they are most likely to be illegal.
 Regards Nick
Thread: Copyright
24/08/2010 09:09:03
Hi, copyright can be quit a complecated issue. I have been reading Niloch's link to a previous thread, where one member said they had scanned articals and sold the mags on. It is possible that this is in breech of copyright laws. I believe you are allowed to copy material for your own private use, but you must own and keep a copy of the origanal. If you sell on the origanals you must also pass on copies or destroy them.
