Renovating a Burgess BK2 Bandsaw

Bizibilder bought himself a wreck of a bandsaw about three weeks ago for the princely sum of £20 – A small tabletop Burgess BK2 two speed model probably made in the 1970’s.  Unfortunately in his haste to get on with the job he forgot to take any “before” pictures!

Suffice to say it was a sorry sight – 90% complete (the whole upper blade guide assembly was missing), both the machine and its motor, were full of sawdust (bandsaws always are!!) and looking as if someone had painted over the rusty bits and scratches with an old rag soaked in the gunge found at the bottom of an old tin of silver-grey paint.

Three weeks later and it is transformed! 

The whole machine was stripped down into its individual parts – which included drilling out some pop-rivets (I suspect some of these were original and quite a few not!), and completely dismantling, cleaning and reassembling the motor. All the main aluminium castings were “wire brushed” down to bare metal and the corroded steel parts, nuts and bolts etc. renovated or replaced.  A couple of coats of primer and yellow gloss for the insides and two coats of Hammerite silver on the outside got things looking better (£10) – The base and motor were sprayed dark green as Bizibilder had a spare can!  With a new blade and drive belt fitted (£15) the whole thing was reassembled.  A couple of evenings making a rather nifty new upper blade guide and the machine was complete. Bizibilder even cleaned and reused the original labels.  Total cost £45.

It is now “better than new” – especially with the uprated ball bearing blade guide! and should be good for another forty or so years service.

A few pics of the finished article:

Last chance for those AR’s

Just a couple of tiny AR's today - Remnants of the two that have been on view for nearly three months:

The Sun today with returning spot groups

A couple of active areas on view - third time around for both?  AR 2673/2674 then 2683/2682 and now 2686/2685.  Seems likely.

An awful Sun image!!

The seeing today was awful and I almost gave up trying to get an image of the Sun at all – not the best of images:

Daytime Moon

A daylight Moon - After a regular session photographing the Sun I thought I'd have a go at the Moon too!  The moon was high in the sky so it gave a good opportunity.

ED120 APO, Canon 1100D, 1/640sec, 100 single frames taken.  PIPP was then used to crop the frames followed by AS2! to stack 60 from the 100 taken.  Then Lucy-Richardson deconvolution in Astra Image to sharpen.  Quite a few gentle iterations of curves in Photoshop to try and get some contrast back, followed by a tiny bit of sharpening.  The original colour image has been changed to mono.

Autumn Sun

A clear sky when I got home from work - and one of the last opportunities to get a Solar image on a work day as the Sun is now getting low at that time:

A gap in the clouds!

Just enough of a gap to get a disk and one close-up today - I believe AR 2683 is most likely the second time round for 2674.  2682 is still showing tome spits and spots of activity that were much larger last time round as 2673.

Returning sunspot group??

Today's Sun with a new large AR coming into view- possibly the return of 2673 and all its friends?  (see entry for 9th Sept – the Sun rotates once in about 28 days so spots that last long enough can reappear after about 14 days of disappearing as they are hidden on the far side of the Sun).  If it is then we should be in for a good show over the next couple of weeks:

A hazy Sun

Finally found a break in today's clouds large enough to get  an image!  Still very hazy which didn't help:

A very late-in-the-day Sun

A tiny gap in the clouds as the Sun dropped over the observatory wall - just enough to get 200 frames and stack 26 to get this:

Just a small break in the clouds when I got in from work - followed by a thunderstorm!

Quite a show on the Sun at the moment!

Quite spectacular as this is supposed to be the solar minimum!
