Saturday 11th January 2014:

The second Saturday work party this year, I did not write about last weeks, but in summary it was similar to this weeks.

Preparations were made for this weeks main meeting on Tuesday and the Friday/Saturday open evenings for Star Gazing Live.

The steps were swept of leaves and the hall spruced up a a little.

As the year progresses TAWPIA will keep you informed of activity.

Saturday 1st February 2014:

The Saturday before last Saturday there was not a work party because the evening was Star Gazing Live Open evening which was well attended.

Last Saturday there was a work party but I forgot to report TAWPIA 2014 activities. The main Activity was splitting medium density building blocks in two in preparation for continued observatory basement block work.

This Saturday made use of last weeks activities in that some of the blocks cut last Saturday were set in position by the Chairman and Assistant Treasurer who made a nice cup of tea. The Treasurer utilized some of the excess mortar to fill minor cracks in Lecture Hall outer wall to prevent the ingress of bees and wasps which have nested in previous years.

Saturday 8th February 2014:

A busy afternoons activities were successfully achieved by The Treasurer accompanied by a Non-Committee Member of the Lincoln Astronomical Society, the latter brought much appreciated jam donuts to this work party. Between them the outer lecture hall wall was cleared of vegetation and invasive ivy removed from walls. Also following on from last week possible bee and wasp holes were filled.

Meanwhile a not-so-busy afternoons activities were achieved by Chairman and Assistant Treasurer in the Observatory basement where they continued block laying.

Members reading this are welcome to visit on Saturday afternoons between 1330 and 1500.

TAWPIA contingent was 4 this week.

Inside the observatory a USB hub was fitted to the Telescope Pier and the new Guide camera tested. The Treasurer was content with the results.

The Treasurer also prepared a demonstration for new dome guide wheel system to be showcased and discussed at forthcoming Business meeting.

The Observatory door mechanism was adjusted to improve access and egress whilst not compromising security.

Further block (medium density construction) splitting continued using by cutting a groove around the periphery of each with a Bosch GWS 7-115 angle grinder (power applied and switched on) with masonry disk. The actual split achieved by a direct blow in the groove with a bolster hit by a large hammer. 15 blocks were converted into 30 blocks using this method.

A nice pot of tea was prepared by the assistant Chairman accompanied by some biscuits.

It was very windy. The preceding week was the windiest it has been for years. The Site appears to have survived it with out incident.

Although of shorter duration than normal this Saturday was an active and constructive one.

Apologies in advance if this is not the appropriate place to post this message!

Every time I come to a lecture I want to ask, but don't know who to approach, if you would like all of the little seat cushions sprucing up? I would be more than happy to either come and collect them one Saturday and return them the following Saturday, or I could come along to a work party with my sewing machine and do them in the lecture hall?
I don't want to encourage any falling asleep during lectures, but for the members who aren't as young or big bottomed as I am, I'm sure a bit of extra comfort wouldn't be minded :lol:

It was also mentioned that the kitchen was being done up, are any tea towels, cleaning products etc needed?

Saturday 21st February 2014:

A prototype auxiliary Observatory Dome wheel was discussed. The need for this was raised at the recent Business Meeting. The Treasurer took it away for further design review at home.

Other activity was setting up the guide system on the observatory telescope by the Treasurer. The Computer has been kindly reconfigured for ease of use by our leading Astronomical Imager.

Recent Society Gravitational Speaker mixed up some concrete and pointed up the Lecture Hall side door steps with rainwater run off gully incorporated too.

The Chair and Assistant Treasurer continued block laying in the Observatory basement.

As ever time was taken for a nice cup of tea and a donut.

Earlier on in the a couple of casual visitors were guided around the Society facilities to what is believed their satisfaction.

Also in response to Sailor Venus: Yes, please visit on a Saturday and we can have a preliminary discussion about the Society cushions, They have been in service now for nearly 20 years I think. Some may have had the stuffing blown out of them a bit and the seams stressed so the Society is grateful for your generous offer. Thank you

Saturday 1st March 2014:

This coming Friday and Saturday is National Astronomy Week. The Observatory will be open to members of the public to view Jupiter. Some foam was positioned above the low observatory door space to mitigate against the risk of possible bumping of heads.

The Treasurer had been busy manufacturing some auxiliary dome supporting wheel assemblies. The need for the wheels was discussed and agreed at recent Business Meeting. They were subject to an on-site Critical Design Review and judged fit-for-purpose. They will be positioned in the Observatory wall in the next few weeks.

The Chairman and Assistant Treasurer continued block laying in observatory basement in accordance with agreed plan, well over half way now, but a good few weeks away yet until the timber work is installed.

The Assistant Treasurer found time to made a nice cup of tea for all TAWPIA participants.

Next weeks TAWPIA may be a bit thin-on-the-ground due to the evenings National Astronomy Week activities.

Saturday 15th March 2014:

There was no TAWPIA last week as it was National Astronomy Week open evenings on Friday And Saturday.

Both were well attended by members of the Public. Good views of Jupiter, the Moon and the Orion Nebula were seen on both nights.

This Saturday work progressed inside the Dome with the Treasurer assessing locations and heights of the planned additional Dome support wheels so as to relieve stresses.

Beneath the Observatory yet more blocks were cemented into position.

Outside the Dome Mr. G commenced cutting up the large steel access ladders that have been an asset to the society for many years. They had seen work on the original dome build in the late 1970's and subsequent refurbishments. Unfortunately the weather had taken it's toll and some of the heavy plate steps had become detached at points. It was considered at the last business meeting that they should be disposed of and the space utilised for more observing space. The Secretary acquired them from the now long since demolished Whittons Bakery on Lincoln Outer Circle Road.

Inside and outside was given a thorough good sweep by Mrs G. After recent visits this was in need of doing and the areas are a lot more presentable now.

A good 3 hours work.

Saturday 22nd March 2014:

The Treasurer was dome bound this afternoon evaluating strategies with Mr. G for fitment of additional dome support wheels. The objective being to position them at the optimum points to enable the dome drive wheel to remain in contact at all times.

Today saw the delivery of another 15 medium density building blocks. They were split in two to make 30 smaller medium density building blocks.

The steel steps were also broken down further continuing last weeks start.

The 'Committee Room' was made more accessible by Mrs G and the Assistant Treasurer made a nice cup of Tea.

Upon TAWPIA departure at top of steps a welcome delivery was made by Forum member Sailor Venus. She has kindly overhauled and uprated a quantity of the Lecture Hall seat cushions. These will benefit Society Members and visitors alike and their repair is much appreciated. It is hoped that the improved comfort levels will not result in the increased likely hood of audience members at lectures dozing off. In the engineering world unforeseen consequences of modifications can be very interesting; typically during any equipment/system modification process there are several design reviews where experts are present to evaluate potential side effects. Judgments are then made on any changes in risk and additional mitigation procedures included in operating instructions. With reference to the cushions; please gently nudge the person next to you if you suspect them to have dozed off during a lecture.

Other deliveries included some large astronomical poster size photographs that will benefit the walls of the lecture room.

There were a few spots of rain this afternoon too.

Saturday 29th March 2014.

Block laying continued in Observatory basement. A small milestone has now been reached in that the 10th layer has been reached. There are only 2 more to go until the timber structure can be installed.

Assessment of Observatory Dome auxiliary wheel installation continued. It appears that complex 3 dimensional finite element analysis may be the answer. But trial and error may be used as well.

Next week there will be a sports event in Lincoln that will close off Burton Road so there will not be a TAWPIA next week.
