The Sun today - 4 April 2020

For the first time in a very long while a tiny sunspot!!  We have just been going through a Solar activity "minimum" where there are few spots, if any, for some time - this time round nearly a whole year!  the complete cycle takes eleven years.

31 march Moon

A three pane mosaic of the Moon - each pane in turn being made of three coloured channels - using Red, Blue and green filters to produce a colour image.

A long wait but at last a Moon picture!!

Not managed a Moon picture for nearly a year!  Simply too busy!!

However I did manage this tonight:

More progress on the whatya-ma-call-it

Quite a few hours machining have gone int these two blocks of cast iron.  These are the main "frames" of the machine.  Lots of cutting out on the bandsaw and cleaning up using the milling machine:
The machine is officially called a "Bonelle" Tool and Cutter Grinder. Designed by James Willis in the late 1990's after an original design - The "Quorn" Tool and Cutter Grinder designed by Professor Dennis Chaddock in the early 1980's.  The original "Quorn" being made from castings and the "Bonelle" being made from stock sections of steel and iron (along with quite a few modifications as well).

Fishing again - 21 September

Caught a few carp and spent a while watching a rat eating someones left-over bait.

And realised that the Moon had not yet set!

Havn't posted for a while...

Not much Astronomy going on as the Sun is more or less spotless at the moment and the Planets are not well placed for viewing (too far south in the sky and close to the horizon at best).

Bizibilder has, however, managed a few fishing trips........

(You should deduct one pound from the weights shown to allow for the wet landing net! 😎)

More bits of the whatya-ma-call-it

Bizibilder has been working on this project for a while and these are a few of the bits already made:

These precision ground steel bars are part of the main frame of the machine - they are around 15" long.  The shorter one at the front is a partially made boring bar that will be used shortly to bore some holes in the cast iron blocks seen in the previous post.:

These bits are various fixtures and fittings required to hold everything together eventually.  All made from free cutting mild steel:

And finally - a device for cutting the divisions on the several scales and micrometers that will be part of the machine - Bizibilder had to stop work and make this as he would have been stuck without it - tools to make tools (There will, no doubt be a few more of these before the project is finished)!

By moving the handle forward and backwards a tool bit, held in the ram seen protruding on the left, can be made to cut fine lines in the workpiece. The knurled knob on top allows the line length to be selected to show the longer and shorter "fives and tens" lines of the graduated scale.  The whole tool is about 6" long.

Bizibilder is building again - this time a whatya-ma-call-it:

See if you can work it out! (Hint - it is a specialised machine tool of some kind)

Some large blocks of continuously cast iron - 50mm (approx 2") and 40mm ( just over 1.5") square.  The longest piece being machined on the milling machine is 11 inches long.  These are only just within the capacity of Bizibilders machines!  The first two pieces shown here are the offcuts to be used later and are 6"-7" long:

The general idea was to machine the four long sides of the block flat and get them all square to each other and the opposite sides parallel - nearly four hours of machining later Bizibilder had made this:
Cast iron swarf!!!!! (or at least a small portion of it!)
Each side of the block took about half an hour - about 10 mins actual machining time and 20 mins to keep moving the clamps to allow the cutter to pass.  As the bar has slightly rounded corners (due to the manufacturing process of continuously cast iron) these will be tackled later - probably by hand filing - they don't have to fit anything and can just be "cleaned up" to look pretty.

A swift walk around the garden this morning

A few flowers to see:

Found these in the camera - from a month or two ago:

A Fine sunrise and an equally fine double rainbow

April 10 Sun - with a decent sized sunspot too!

At last, after several weeks of minimal activity in white light a decent sized Sunspot to see:

The Moon at Last!!

My first Moon of the year (in fact my first night image since last November!!)
Seeing was pretty wobbly but at lest I managed something.  Four pane mosaic using the 120APO and ASI120mm mono camera.  Each pane a stack of 100/1000 frames.
