Mounting the work like this means i could machine all round the part in one go ,making all the edges parallel and square .

Thanks Lads  :beer: :wave:


Well did a spell in the shop tonight  a bit more work on the motor mounts , I am using my 20 year old RF25 mill/drill to bore the mounts.
I used a hole saw to remove most of the material , witch left about 1/8" for boring , using the hole saw also means i dont have to move the head on the machine and loose alignment .
 
Bored to size , finish is Ok for an old not very ridged machine .
 
Thats the screw end done .


The motor end was done much the same way , just is an oval , bored both ends which leaves a little bit between the two too mill away .



I use mild steel bar ground up for parallels so it dose not matter if i machine into them .

Rob

Man after me own heart, can't see what all the fuss is about hardened and ground parallels accurate to a given size to the nth micron.

Much prefer stock size ground down to a matching set. Plus points are if you use a 1" wide parallel it won't allow it to grip a 1" bar, toss up which one is held the tightest but if you grind 5 or 10 thou off to clean up they will always grip an 1" bar if you do have an accident it's doesn't cost you an expensive tool and possible harm a job.

This tip is only for the unwashed, that twat in the yellow mac obviously knows all this so I don't know why I waste my time posting instaed of making more Ju-ju dolls.

Been a bit slow of late  :palm: , anyway did do a bit to the motor mounts .

Set up to round the corners , using the angle plate i made earlier and a stop , actually a cam roller from a fuel pump CAV i think .



once set its just a simple job to turn and flip part to do all four corners on both mounts .


Next the motor pocket , more cam rollers used to position the work on the mill .




Next the slots for the motor fixing screws . no DROs in my shop i use gauge blocks and the likes ,no battery's required   , after using edge finder to locate position of first slot , lock X stops
for the slot length and Y stop for first slot position , move Y to next slot position and lock stop .

work fist position .


Second position .





Remove gauge blocks , that are set for  the pitch of the slots , and slide job down .



Had a nice run up to Scotland today , picked up a new toy ,,,,, thanks Darren  :beer:


must resist urge to fiddle with it  :palm:

Well spotted Dean I didn't think this latest Ju-ju doll was working, obviously is, just needs tweaking a bit or a bigger bodkin.   :zap:

Thats his big slot to match the small slot  , no point in having a round hole and slots the motor has to be able to move

nither am I the bumpy bits in the main hole are the result of lengthening the large hole to make a BIG slot to allow movement two big holes with centre offset by say 10mm

Yes, but he SHOULD have milled them away so the edge of the slot was the usual baby-soft chrome-plated wonderfinish...

But, for some reason, Rob chose to not only take the half-baked route, but after his previous work dared to show it in public! Either that, or the Stevenson Curse is finally taking effect...
Cheers!
