Summer 1990 Rotary Table

Hi Dr. MC Black, glad you find the photos better. I was not offended about your comments. Those scans were done many years ago and PDF editable programmes cost more than I was prepared to pay and the idea of the overlapping the sheets, was so that anyone could print them out on an A4 printer, trim a suitable side and attach to the next page and thus produce a drawing of the same size to that of the originals. Being there were a large number of these various plans, they were did this way to produce something useful and I could apply the same template to every drawing, they still took a fair amount of time to scan, as each side had to be scanned from both ends and then stitched together and then each scan had to be cropped four times to produce the separate pages. You can produce a decent size drawing onto a A3 sheet of paper, using the full scans, but of course they will be only a little over 50% the size of the originals.

Regards Nick.

Clearly he knew the convention because it's used throughout the rest of the drawing! Just a typo I think. He made another minor mistake in the copyright notice, possibly not corrected because it's too much work by hand:

I found it surprisingly hard to suss out Ⓑ. I didn't tune into the drawings well. If I were building the table, I'd redraw it in CAD to make sure I understood it.

I did nothing more complicated than enlarge the drawing so that the element for each part filled an A4 window on my screen and then printed "Current View" on A4 sheets.

I notice that in many places on the drawing, the draftsman used a " (inch symbol) before the decimal point - but NOT consistently.

I notice that the holes on the 2.5" and 3/4" circles are only shown for part of the circles (say between 1 o'c and 5 o'c) rather than for the entire circle. Any idea why, please?

If Mr. Daish is a subscriber to this forum, is there any way of contacting him, please?

Very many thanks, in anticipation, for your continued assistance.

I must be losing the plot! The start with a zero convention most certainly isn't used throughout the rest of the drawing. DrMC is right. My excuse, I was looking at another plan at the same time. Sigh...

Neither excuse or apology is needed or expected.

I wonder if the copyright notice is invalid because the name of the company is wrong!

Intellectual Property Lawyers would make a lot of money out of things like that!

Has anybody other than Circlip actually made one from the drawings?

With best wishes and thanks again.
