Yes I get that John, but what about the thread pitch, etc. Not to mention M6, M8 etc. Like M8x 1.25...

You can get thread gauges for testing the thread pitch.  Some metric sizes do come in two (or occasionally even three) different pitches, but I don't recall seeing much other than the "standard" pitch for astronomy, with the possible exception of filters and T2 connectors, so if you buy an "M8 bolt" you're pretty likely to get the right one.

A thanks James. I suspected it would be complex 🙂

BTW, I think the last time I saw an Acme product was in a Road Runner cartoon 🙂

And a bit of light reading. 😀

Looking forward to my set arriving,
I think I purchased my set a day after yourself John, so fingers crossed they arrive soon.

Sadly just yet another copy invoice sent from Springer, so far no shipping details.
Clearly direct from Springer was not such a wise move.

Ordered mine on the 8th and they said it would arrive on the 18th which it did. Delivered by Elite couriers which I’ve not heard of before.

I ordered my set on the 9th from Springer, so far only an invoice and no delivery or tracking notifications.

Perhaps you've gone up a level in your frequent flyer status with all these orders, John

Acme thread table

From dad's 1943 "Machinery's Handbook".

Yet another book arrived this morning from Book Deposatory,  via carrier pigeon. They informed me it was "winging its way to me" on April 3rd. 

I haven't read any of it yet, just looked at the pictures, but I must say it looks a promising read. Lots of nice refractors - which Neil E has the Hot's for deep in his heart. One day he might write a best seller entitled "Takahashi"!

If I owned that table, I'd have to paint the underside greeny-grey-blue and mount a waterline model of a ship on top!

A little 500gb PCIe SSD. Small but fast, hopefully will speed up stacking.

At the mo all my astro files are on a general drive, now I can put them on their own.

The postman today, primarily bought my "light" filters for my small refractors 100mm and below. The filters are Wratten #56,#21#23A,#8,#82A. I got these as an upgrade to replace my Tal filter set. As the Tal filter set, doesn't have any Wratten numbers on the filters or even general nomenclature like "light red". I suspect the Tal filter are normal filters not "light" filters like I need.

I like these new filters as they have the Wratten number on them. Plus they come with pretty good cases, which I didn't know at the time of ordering!

Slightly overdue L-Bracket & Sky-Watcher UWA 58° 6mm planetary eyepiece, betting on teasing 216x out of the Skymax 102...

Not much. Just a 55mm to 48mm step down ring so i can use 2” filters on my compact camera. Just needs a small amount of zoom to avoid vignetting.  🙂

You’re the one stopping me buying these on eBay!! I found they for my 50mm bins and a 135mm camera lens... hopefully have the ones I need.

That's not bad at all.  I'm planning on doing a NEQ6 soon and it looks like quite a lengthy procedure by comparison.
