Thread: Stanley Hand Drill
06/03/2011 11:56:28
Glad to see david williams getting help. He did not give the model number of his venerable drill and it is not surprising if spares are not available today. In their 1992 price list, however, Stanley list spare jaws and springs for all of their hand drills including two models then discontinued. Their motto then was "The best tools you can lay hands on".
Thread: Forced lubrication
05/03/2011 18:52:35
I have just come across your post. I couldn't see the particular Warco mill you mention in their current catalogue but I believe this lubrication method is very common. The corresponding oilers on my own Warco machine are located on the long *vertical* faces of the table and I have never actually attempted to use them, preferring to oil the ways directly. There is in any event no provision on the Y axis so these ways have to be lubricated in this way. I don't find it necessary to loosen the setting of the taper gibs and would regard this as something to be avoided if at all possible.
Pumped lubrication seems more appropriate for a machine in constant use and my thought for an improvement would be the incorporation of accessible hydraulic nipples; if you know where to get an affordable *non-leaking* oil gun to feed these then please let me know!
Thread: Bench grinder flanges - to fix or not to fix?
25/02/2011 19:43:13
HSE advice (see hsg17.pdf on their website) is that the inner flange on grinders over 560 W should be secured to the spindle to prevent rotation. I have seen an 8" 900 W machine whose inner flanges were not secured other than by the friction of the securing nut and, noting that it carried a "CE" sticker, wondered whether the HSE requirement had been relaxed by Europe (the HSE document mentions the possibility of revision).
I have experience of two makes of 6" grinder both of which had the inner flange secured against rotation by a pin and this arrangement is shown as "normal" in Ian Bradley's book "The Grinding Machine" published by MAP in 1973, although the use of a pin is at least 100 years older.
We are all aware of the danger of wheels bursting. My impression is that the captive inner flange reduces the need to tighten the nut, over-tightening being one of the known causes of wheel failure. I have as yet been unable to verify whether the requirement has indeed been waived by Europe or what the reasoning for such a change might be. Any comments would be welcome.
All this might seem rather theoretical - we just want to sharpen the tool and get back to cutting metal - but it should certainly concern anyone thinking of buying a new machine. Grinders are sometimes designated as "offhand" but we probably should not be!
