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:

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.

Sun pictures again!!

Not taken a Sun pic for three months!!  However all is not lost as I have only missed a dozen tiny spots as we are passing through solar minimum.

Usual rig of 120mm APO refractor, Baader Solar film ND 5.0, Canon 1100D, ISO 100, 1/3200 sec exposure.  120 still frames taken.  Trimmed in Pipp and then stacked in Registax 5.  Photoshop to finish and add false colour.

The Moon with X and V on display

A bit slow processing these but finally done - The Moon with the "X" and "V" on display from last night.

ED120APO, ASI120mm mono camera, 2.5x Powermate for the close-ups.  Processed in PIPP, Autostakkert!3, Astra Image and Photoshop for a final tweak!

The main image is a five pane mosaic - each pane 200/2000 frames taken (one was a pig where the scope/ camera or something moved and I had to crop about 50 frames from the end of the AVI - I think i may have walked past the scope and I must have nudged it! :hmh:

Close-ups as above ie 200/2000 frames each pane - one a single and one a two pane mosaic.
