|Thread: Milling Table "fault"|
Hello all, Im taking it to pieces tomorrow. The reason Ive come across this error now is because Ive always assumed every thing tobe correct, until I measured a piece I had machined for accuracy and was shocked. The DTI base is clamped under the head, rigidly too. Ive reasoned that if the column, which is bolted up solid, were at 45 degrees to the vertical, it wouldnt make any difference. Unlikely I know !.
The mill is in supeb condition, and not really over used. I did most of my machining using a Jones and Shipman vice (stupidly sold!!!) which is probably why I havent noticed anything . All the later work ona vice machined from castings by me, which is out on it sliding surface by this 10 thou .
Anyway , everybodys advice is much appreciated. Thanks.
Duncan, Paul and XD351 ; as you are all saying, Ive got to measure the thickness of the mill table for a start and then the table underneath too if necessary. Im getting the same error all the way along the mill table. Im going to remove the table and put the parallel on the table below it and measure that, the Y axis, if that makes sense. It seems that one of them needs regrinding. So much for Austrian quality control. Thanks toi all.
Gas mantle, yes I do. The parallel itself is accurate to a couple of tenths over its length and the Noga DTI set up is rigid. Ive had the mill for about 10 years , this being the first time Ive noticed this error. The reason Im checking now is because a milling vice (5 inch width ) I machined 2 years ago, checks perfectly along its length, but 10 thou out across its width, the length clamped to the table on the X axis during the job.
Im beginning to think that the mill was sold because of this fault.Im convinced just about , that the table will need regrinding. Oh bother !.

Neil and Pete, yes I will try out your suggestions. I have thought about the column being out ( it is bolted ), but cant see how it would make any difference, however, I will definitely try it . Hope Im proved wrong !!. Many thanks.
Hello all, on my milling machine, an Emco F1P, I have found which I presume is not right, nearly 0.010 inches discrepancy over 5 inches of travel on the Y axis. The parallel I am using is perfect, there is no lift in the table and is fine on the X axis travel. Not knowing a great deal about mills, I am guessing that the top surface of the table isnt parallel with the bottom across ways so to speak . Oh, and the top surface of the table is unmarked.
I would be grateful for anyones help. Many thanks.

Where does the " father " bit come in ?. Im confused !.
|Thread: Drinking and Driving.|
If it were up to me, the first time you are caught drinking and driving, banned for life. To be banned 4 times is a bloody farce. I know its easy to be " holier than thou ", but making a mistake whilst driving is easy enough without drink inside ones body, never mind being pissed !!.
A rant about our useless drink driving sentences......
My 43 yr old d.... head of a nephew was caught drink driving for the 4th time, 3 oclock in the afternoon, after crashing his van whilst asleep. 123mg / ****, well over. Just had his courtcase and sentenced as followed ; 32 month ban reduced to 2 years if he attends alcohol rehab course, 200 hrs c/ service and £ 175 fine, which includes court costs !!!!!!!!!!.
The law really is an ass.

|Thread: Mobile Phone Mast Installation|
Wish we had no mobile phone coverage, nobody talks to each other any more. Sick to the back teeth of trying to converse with people( including our kids) who just cant stop gawping at their phones.
Sorry for the rant.
|Thread: Silent Air Compressor|
My original compressor was a good unit and worked very well,, but the noise , bloody hell !!!!. Standing outside with the garage door shut was still embarassing.
James, I bought one about a year ago, fantastic bit of kit, very quiet too. Would recommend one in a heart beat.

Ian, one can only hope he died a slow painful death. I sometimes think humans are evolution's big mistake.
Reading about the fantastic work people do to help animals reminds me how much Im looking forward to reading the Duke of Edinburgh's obituary. he has shot many of them including at least one Bengal tiger. Roll on......

|Thread: Burglar alarm|
The law is wrong in my view, mainly that there are no deterrants to help stop the crime in the first place and generally speaking, the police are crap. I was told recently, that if you get caught driving off with snow on your vehicle , you could be in for a £1000 fine, but for burglary, first offence, a caution.
Their price for 75mm × 50mm× 3mm box section steel is a bit pricey, at £74. JD metals, £40 including delivery.
