Got some more done....... After the 3 into 8 won't go conundrum, I paced out the faceplate holes accurately, on my rotary table. Just squeezed in........ Sawed away the excess diameter. Note the obligatory scratch........ :bang: :bang: I'd marked off the holes in the pan freehand, with dividers and centre punch. It fitted perfectly on the "precision" placed studs. Nice to know I can still mark out accurately! :thumbup: Skimmed o/d, and both sides, then swapped to some precision, thin cardboard........ This allowed accurate facing away of the radius, leaving a truly flat disc...... Found it very difficult to get the scroll spinning true..... Until I placed the drill chuck close by, and tapped disc true with lead tup. Topped, and bored to 1.5"....... Will turn a spigot on the 2" boss. Should look something like this....... Rear view........ Two of the holes will fix the balance quadrant. The other will have a plug fitted. Next up, is recycling the boss. Nowt much goes to waste here! Plugged the spoke and grubscrew holes, ready for re machining...... More progress, sometime next week, probably....... David D |

Yeah looks good that David, how thick is the frying pan base? |
| Stilldrillin:
Thanks Chaps! :thumbup: Thickness is .085", in the centre area Nick...... Does anyone think, this is taking conservation of resources a little too far? :D David D |
