Thread: Locomotive Suspension
18/09/2010 17:33:55
Gentlemen,
      I am building a Sweet Pea 5" gauge 0-4-0. I have got as far as a full set of frames and now need to fit wheels, axleboxes, springs etc. I wonder if anyone who has built one of these locos could possibly tell me, firstly, if they used the Blackgates springs, and secondly how much they shortened them by.( I have tried asking this question on the Sweet Pea Forum but got no replies)
Thread: Dangerous Practices
14/09/2010 22:46:57
I feel that I must agree entirely with Crewmech, this article is aimed at beginners, correct practices should be followed. In years to come people will look back at these articles for instruction and this bad practice, because that is exactly what it is, will be perpetuated. I was fortunate to do a proper engineering apprenticeship and if I held work in a similar fashion I would have been sacked. I also went on to run my own business for many years and if I had seen an employee carrying out this dangerous practice I would have sacked him on the spot. I do not care what any of you get up to in your sheds or garages, it is when you commit your dodgy practices to paper and publish it as beginners articles that it matters. Regarding the double sided tape, the steamchest cover should have been gripped in the 4 jaw and faced, then reversed in the chuck to face the other side. Shame on Mr Hall for his bad article and bigger shame on the editor for allowing publication.

Thank you all for your replies, I have more than enough information now to tackle the job, hopefully it will be done sometime over the weekend.

Gentlemen, I wish to cut a worm about 1 inch diameter to mesh with a Myford changewheel. Can somebody please tell me what pitch(TPI) the worm would need to be, and also what angle tool would I need? I am making a loco building stand for Sweet Pea and want the worm drive to rotate the loco. The price of a commercial worm and wheel is enough to make your eyes water. Thanks in anticipation.

Thread: "Foundation" book has got me worried
26/04/2010 17:24:23
Hi John,
Like you my workshop is in a garage, a detatched double to be precise, single skin, no insulation and no rust. The secret is to run a dehumidifier constantly.
Thread: Frame material for Tich
04/03/2010 19:06:42
Hi David,
 
   Nothing at all wrong with using gauge plate for frames, I use it in preference to black or bright steel as it does not spring when cut. The only disadvantage is the price but I think it is well worth it for nice flat straight material. Frames should be rigid, look at all the stretchers etc used to brace them, I agree totally with Tony on this point.
Thread: Badger Mini Abrasive Gun
19/02/2010 19:51:51
I also have one, about as much use as a chocolate teapot. Eventually bought one of the Machinery Mart benchtop ones, needs a bit of work doing to it to stop grit coming out in a fine mist everywhere and also a big compressor but at least it works, and yes DO IT OUTSIDE

Still waiting for mine in Hampshire.
 
Thread: why cant you silver solder in the workshop?
01/01/2010 18:34:18
Hi Dave,
      
         Apart from the condensation that may or may not be caused, I think the real reason is due to the fumes released from the flux and the cadmium fumes released from the silver solder rod. Most instructions say to use in a well ventilated area, whatever that may mean. Personally I silver solder small jobs in the workshop with the door open but try to do larger items outdoors, weather permitting! 
Thread: myford boxford or colchester
28/11/2009 20:05:33
I have had a Colchester Bantam Mk 1 1600 revs for more years than I care to remember and I have nothing but praise for it. I very rarely use it above 800 revs and I would consider it to be far superior to a Boxford and much more solid to use than a Myford.
Thread: Cutting male threads
14/11/2009 13:33:06
Hi Chris,
regarding your Lancia thread, it is still common practice in industry to b***tardize a thread either by an odd diameter or an odd pitch. I work in the aerospace industry and our products have "home made" thread sizes so our competitors parts will not fit. I agree totally about the internet as a resource but I still like an old fashioned book to read in bed when I cannot sleep.

Regarding books on thread data Machinerys Handbook published a book solely on screw threads, about 290 pages worth. My copy is edition twenty with a price label for £1.95 and was published in 1972. It appears to cover a lot more threads and in greater detail than the traditional Machinerys Handbook
Thread: 3 ½" Gauge Association
08/10/2009 17:28:07
I agree entirely with Tony and Alan. I would most certainly join if such an association existed
