More drilling and grinding on the frames

Matt has been hard at it with the grinder and drill again!

A large number of rivets on the frames have been ground flush and blow holes drilled to enable the rivets to be removed.  The rivets that need to be removed include the ones holding the footplating to the valance frames, those holding the valance on and those which hold the foot steps in position.
This is all to allow us to remove the existing bent and distorted valance plates in preparation for new ones being cut to size and installed.

The new valence plates will be cut using the CAD model produced by Matt and shown on a previous post. The reason for grinding them flush and drilling through is to reduce the risk of a blow back of hot material when the burning out of the rivets takes place. the holes allow the moulten material to pass through and make a tidier job all round.
The drilled and ground rivets following cleaning
The valances, it has been decided, require replacement due to the amount of distortion present in the existing ones. this is due to a long active life and a couple of shunting incidents following withdrawal from service in 1974.

The rivets holding the steps to the valance have been drilled and ground flush
When the old valances have been removed, they will be kept to confirm the design of the new set before being sent for recycling. The steps will be refurbished and new cast treads will be cast to allow them to be further used.

The work continues apace and hopefully this will be the last few bits to be removed from the frames before they start to have things put back on to them!

We are currently fund raising for a new set of cylinders for the loco ( a second set will be cast at the same time for loco No.178).  The cost of the casting will be in the region of £7,000 with the cost of machining and transport adding another £7,000 to £8,000 to the cost making a total of around £15,000. If you should happen to know anyone who has recently won the lottery, please point them in our direction!

We are a totally self funding sub committee of the Bluebell Railway Preservation Society, so every penny spent on the loco needs to be raised by receiving donations, selling gifts and items of interest or taking more valuable donated items to auction.

Another update from Matt

Frame Drawings

As well as a full time job, driving steam engines, looking after his partner and having a social life, Matt has continued with the production of CAD drawings for the locomotive!

His latest offering is an advance copy of a 3D CAD model of then frames (complete with cylinders and stretcher bars installed!

The right hand frame view. 
ll pictures are from CAD files produced by Matt Holloway

The plan now is to use these drawings to produce water or laser cutting templates for the frames and stretchers, especially the section at the rear of the loco which was eaten away by the corrosive action of the coal dust mixing with rain water.  There is a probability that the drawings will need to be modified slightly to allow for the modern metric plate, but that will not cause any great problems.

An oblique view from the front RH corner clearly showing the frames, valance, cab and bunker floor buffer beams and even lamp brackets!
Once we are happy that the current frames can be welded (aka the hole repair Stuart (skid) Marks is attending to) Matt will finalize the rear of the frame cut lines and CAD models for the rear frame sections ready for water or laser cutting.

We are going into some exciting times in the not too distant future!

We are hoping to be able to set up a PROJECT 27 Facebook page so please watch this space for further details!

Of course our current fund raising push is for a set of cylinders to be cast and to this end we will be next at the Railway with our fund raising stand at the Vintage Transport Weekend in the Field at Horsted Keynes.  We are having this month off active fund raising, but will always welcome passive funds!
