So,, at the moment inertia due to the fact that despite it having soaked in WD 40 for a good 10 hours the hex screw on my needle bar won't move. Subsequently I can't adjust the needle bar and the sewing machine itself must remain inert.
I tried putting the metal panel that the light is attached to back on the machine only to find that it doesn't connect to the column. I guess on closer thought it wouldn't, since the needle column has to be free standing in order to move right. Had just thought wit it going back on it might steady the column and I would have greater purchase on it and thereby be able to turn the screw.
 I remember the first time I tried to turn the screw lower down that allows the needle to be changed it was very very stiff and had to sit in WD 40 for a while. I think I actually pretty much gave up on it and went down town, came home and it was able to move. No such luck so far with this damn hex key. I'm just watching the hex key nearly bend in the middle from exertion, or looks that way. maybe I just need to put more faith in it.  It's a metal hexagonal bar on a plastic handle & I'm just wondering if it might be easier to turn if it was shorter. Not sure what that means in terms of leverage though. I know that with some leverage the longer the handle/lever the greater the force applied but since this is sticking out horizontally from the fulcrum and doesn't have length in a dimension that extra force could be applied as far as I can see I don't think that applies. maybe I need a wrench or something, pair of pliers, that I could attach to the shaft and turn things that way? Is that the way it works?

Until such a time as I can get that screw to move, work with  the sewing machine is at a standstill. Maybe I need to move onto cutting things out in preparation for the thing to fix itself? Pockets which I might have been better off working on yesterday instead of that  bib, still need to be done. Really should have gone and refilled the bobbin  and finished off the buttonholes on the bib at the time I was doing them,. Think I'd been letting eating get very late, possibly even had food getting cold at the time so had placed a fullstop on the activity without finishing. Thought things had been getting good up to that, what with the tension on the stitching finally having been corrected. I'd even gone back over whatever stitching was already on the shirt yesterday morning before the problem began. Well, spilt milk doesn't really do anything but make a mess. So counting my druthers isn't going to make it any better is it?

>>>>>5 hours or so later I'm back with a set of Stanley Hex keys that are the standard shape not the straight stick with a handle type that I presumably got given in Maplin's several years ago. Those I had may have been designed for more delicate work on a computer. Whereas what I take to be the standard shape is more L shaped or rather short shaft, long handle which is more the other way round than the standard letter shape.  Not tried it yet but hoping that it will be exactly what I'm looking for.
Also hoping that something I heard about today which might turn out to be a C.E. scheme or something based in upcycling things as clothing and repairing donated clothing comes to fruition.

Also need to check up what patterns are available for men's clothing from Burda since there is a sale on the label in Hickey's. Just looked at a mid 19th century outfit that looks like something from Dickens or other costume drama before I left there earlier. Want to see if it's worthwhile though.
