Thread: Thread dial indicator

     Nigel, HI.  A rotating rack would comprise a series of rings, it would not
    be a screw, so you are not quite right.  I can't say what is right though,
   sorry.

     I can't ignore the blinking ads and I have noticed that Warco offer a
   Hugh range of lathes and mills.  I presume that these are made in Wales.
Thread: Lament for a lost grease.
21/03/2010 11:21:54

     For moisture resistance, CL is the Beezeneez but it is not Castrol Medium!
   Steve has got the point, it is lacking in greaseworthiness.  The calcium
   ( or lime ) base is just coincidence.
19/03/2010 18:11:32

     Castrol LM is lithium based, not lime.  My tub of LM has a list of Castrol greases
   on the side which includes Medium.  LM is excellent in its way but it is stiffer than
   Medium
19/03/2010 12:52:49

     Once upon a time, when the world was a better place, it was possible
   to obtain "a general purpose lime based grease for use where there are
   no high temperature requirements"  It was called Castrol Medium Grease.
  
   Castrol Medium was honey coloured and opaque, it was quite unrivalled
   for greasing things that needed greasing. Nothing could touch it.
 
     I am sure that Castrol would say that their current range includes
   products superior in performance to Medium, whatever application one
   might chose but they disregard the emotions of the user.
 
     Happily, I have enough Medium left to see me out but I must not be
   selfish and I truly feel for those in a less fortunate position
       
     Please tell me that I am wrong and Medium is not discontinued !

     My silly question for today;  has your battery gone flat??

Thread: Hallam Engine
27/02/2010 07:57:49

     10cc is 0.6 cubic inch.  Hallam 60 signifies the capacity.

     I know v. little on this subject, so please understand that my questions
   are questions and not sly suggestions!
     a) Would it be an awful nuisance to arrange the ignition timing to be
   variable during running?
      b) Is the load in the right parish? The engine note strikes me as one
   that would tell a great deal on this score to a chap familiar with the engine!
 
     Great project! I much enjoyed watching the video.  More power to your
   elbow, and please keep the experiments going.
Thread: Oil for Lathe GearBox
24/02/2010 01:29:10

     This is far from being the first "Oil" thread that we have had and the
   answers seem to be no more authoritative than usual.  Any old oil is
   better than none, no doubt, but the amazing differences between the
   solutions adopted above are horrifying when the damage that might
   be done to expensive and treasured machinery is considered.
 
     Could an eye be kept open for a "Workshop Practice" author to get
   it all sorted?
Thread: Lower Price Optical Rev Counter Accuracy
23/02/2010 15:05:18

     Well done Les!  That's put that one to bed.
23/02/2010 11:47:53

     I think you are being too pessimistic Martin.  They have to click a spare
   genny onto the grid without all the winding up that they used to do.  Life
   is too short for that nowadays.  By the standards of we agricultural
   mechanicals, the 50Hz is very good indeed. 
23/02/2010 04:52:31

     Something wrong surely.  Have you forgotten the flashes from
   the -ve half cycles?  Anyway a 3jaw will appear stationary @
   2000 rpm under 50 Hz lighting
Thread: Has anyone any experience of HQSS tools – notably taps and dies?
21/02/2010 22:39:19

     Just for fun, I Googled Totem and  found an unequivocal assurance
   that the wooden boxes in which sets of taps are supplied, are designed
   and made in UK.  No such assurance is given about the tools however
   so my assumption is that they are foreign.  Seems likely that Julie is
   right about India.  There was nothing about a distinction between HQS
   and HSS that I saw.   All very funny.
Thread: Measuring tool accuracy
21/02/2010 10:41:30

 
     Back in the summer, when Peter first started this post, I thought it
   would be a good idea to try out my own kit. In general, I was reassured
   but decided that I had to make a micrometer stand in case I ever did want
   a good answer.  I confess I have not yet done so.  I was impressed by
   my 1-2-3 blocks, which do seem to be 1-2-3! and horrified by my school-
   type protractor which looks nice but is desperate!  Altogether a worthwhile
   exercise
Thread: Diamond tool holder.
20/02/2010 23:21:44

     Excellent though most aspects of these ingenious devices are, it seems
   to me that there is a difficulty that has not been mentioned.  On intermittent
   cuts, there will be a tendency for the tool to be driven down into the holder
   like a tent peg and some sort of positive means of preventing this would
   be a good idea.
Thread: Drill Chuck, Dismantle
15/02/2010 10:42:08

     Important for use as thinner for paint is the fact that White Spirit
  all evaporates.  Kerosene ( paraffin oil ) leaves a thin oily deposit
   of low lubricity.  This interferes with the drying of paint and is also
   is a nuisance if left in bearings.
     At one time White Spirit was also called Turps Substitute but I
     believe that this is now a dfferent but very similar product.  In
    B&Q, you can often find them on adjacent shelves.
Thread: diamond grinding wheels
10/02/2010 14:10:26

     Someone recently (yeah, I know! ) pointed out that liquid iron dissolves
  carbon and so, if you grind ferrous metal fast enough to make sparks, you
   will lose your diamond quite quickly.
     Perhaps this is why Ramon used diamond only for tungsten carbide.
     Did Circlip's burrs cut fast enough to spark?
     Has Dias's wheel cut enough to reveal a drastically reduced life?
     Has anyone used a diamond wheel on iron long enough to answer
   this partly remembered caution?
