|Thread: What Did You Do Today 2021|
Not today, but over the last 4 days, worked on the bits below, plus sweat, blood and expletives deleted !!
and more elbow grease and the silicone variety ... ended up with this
An unusual design and manufacturer. the shaped work holders rotate individually and accurately match for height - 4 total approx 1/4" thick. Very substantial (heavy) and good for mill or drill.
Anyone else come across this type ?
|Thread: RAF to give up flying planes.|
The Royal Air Force (British version) has never flown 'planes' ... those have always been the province of the woodworking trade group.
Aircraft, or aeroplanes have developed over the years to the extent that the control function inputs are very much on a par with computer control. Indeed, the trend has become for management to encourage the minimum input from the 'pilot' and leave it to the autopilot and FMC ... the downside to this is explored in " the Children of the Magenta" - the upside (from the beancounters) is a reduction in costs.
Personally, having worked with a selection ranging from the original Link trainer, through a variety of VC10, BAC 111, Boeing 37, 47, 77 and Airbus 340, while the response can imitate the 'real thing', they are training devices - not replicas.
I offer my best wishes to anyone attempting to 'make a case' to the beancounters against their intentions.
|Thread: Sort of ... ???|
Bazyle - thank you for the response.
Not sure that all link suggestions should carry a synopsis to avoid wasting member's valuable time - personally, I assess these sorts if things quite quickly and go elsewhere if interest fails ... different folks, different strokes, I suppose.
Just come across this Youtube clip. If you can ignore the presenter, the content is worth watching.
|Thread: Cowells Lathes|
I have both (lathe and mill) and a 'job lot' of accesories. They are decreasingly used, so could be available. The problem, if such it is, is that they are 'cash on collection' ONLY! The lathe is the 14mm x 1.5 version. To avoid any misunderstanding, I have not yet made up my mind to put them up for sale, and, if photos are requested, they will be limited in scope.
|Thread: Broken window key|
Recently saw (on Youtube) a clip explaining that these locks can be easily by-passed, since they don't lock the mechanism, just interpose a 'stopper' on the handle. It is possible to insert a thin strip to depress the 'tongue'.Apologies for rubbish explanation, but a Google search for 'window locks' or similar should unearth the clip.
|Thread: Parkside pneumatics|
Many thanks, Howard and Clive.
Looks like it's going to be a 'home-brew' adaptor - 10-12.
Clive, you are so right about the removal - I don't know what adhesive they use, but, my word, it's very effective !
I have a few bits of Parkside pneumatic tools and a compressor with a flexible tubular outlet. The outlet male thread fits some of the items but not the particular vone I want to use. I need a male-to-male threaded metal fitting to use as an adaptor, but I don't know what the threads are. Can anybody advise please -a nd, if possible where to obtainn same.
|Thread: Lower back issues|
Been a 'member' of this club for many years. Ady's mention of the support belt is a good move - usuallty listed as 'nailer's belts'. Just gone back to wearing mine full-time.
Unfortunately Nature and a local 'sandscaping scheme' have left us with a need to move constant inundations of drifting sand - heavy, wet, particularly and dry. I can load a bucket using a long handle 'snow shovel, but lifting the bucket to wall height to dump it, is beyond me. So ...
... not completely finished, but, it does work and has been proof-tested to 28kgs, which is enough for my needs.
'Proper', competent engineers would undoubtedly make a much better job of it, but I have to work within my limited 'skill' set. The principle has been around a long time - Google "lifting sack barrow" for several variations and power sources. The 'Barrow' was a 'cheapie' £25 job and seems to be standard.
|Thread: Aircraft General Discussion|
Maybe a return to the original subject ( possible erroneous fitting of aircraft components) would help.
The Westland Whirlwind, and derivatives, had been in service for decades before it was (spectacularly !) discovered that it was possible to fit the tail rotor in reverse. Aerodynamics work much better in one direction !
|Thread: Which was the better design of Airship: R100 or the R101?|
Lee Rogers - same problem with helicopters.
All aircraft 'collect' static charge while airborne - static wicks dump the lightning variety and the rest goes through the tyres on touchdown. Helos need to be discharged with an earthing pole for slung loads or through the winchman's body when winching,
We did some trials with the Farnborough 'boffins' measuring the charges accumulated - they recorded values of 175, 000 volts !! During a very strenuous training sortie in Holyhead harbour, I touched down on the Marine craft pinnace with my hand on the cable and mouth open. - amalgam fillings make a good earthing path and the taste of electrical burning lasts a long time !
R I P - he has left a legacy of illustrated method and practice for anyone involved in good engineering - One of 'The Masters'
|Thread: An interesting device, on ebay|
Similar thoughts to Peak 4.
Same sort of set-up as the tool-holder in the Boremasters Tiplap - but surface mounted rather than on a round shaft. The 'trough'. which. I assume, would hold the tool, seems to be limited to one width only.
|Thread: New member from Cornwall|
Welcome aboard - sounds like a properjob, my 'andsome!
|Thread: Horizontal Bandsaw Problems - -Advice Please.|
Thank you NDIY - It was a thought that had flickered through my sub-consciousness before embarking on a world-wide search !
In lieu of any helpful suggestions, for anyone with similar woes, cutting the expanded tyre, and glueing the cut ends to fit, does provide a temporary fix.
Axminster horizontal/vertical two wheel bandsaw. The urethane 'tyre' on the motor drive wheel has stretched and had to be shortened and 'bodged'. with cyano. Works as a temporary fix, but I would like to fit a new one. The only ones I have found so far, come from the States and need a mortgage!. Does anyone have a source which will leave enough change to buy food !

|Thread: Any info on this?|
Well spotted Farmboy - yes, thinking 'conventionally, it is 'left-handed' to use it as a direct lifting device.
"Curiouser and curiouser", said Alice !
NDIY - only "plausible" because of the construction method.
Most Service equipment I used or came into contact with was either of exceptional quality or built like the proverbial outhouse ! This is well made, but not of the highest quality - the output feed roller and the internal chain termination, for example.
From memory, the 'real thing' was metal and the extension was tubular.
Thank you to all for the replies. Yes, the body is Tufnol and very well made. Somewhat oddly, the inboard end of the chain has a bit of wire twisted on itself to bunch up the last three or four links but not secured to the body. I fitted a 3mm screw through the last link and fixed it inside.
The small bomb hoist sounds very plausible
