Malleable iron

Aside

After the spring failed on our back door handle I am having to replace the pair of ’em (after only 22 years, blimey!).  I found this run through of making malleable iron castings very interesting, you may too – if you like that sort of thing.

It’s worth clicking through to the process, lots of photos of hot iron being poured etc. RAL (AKA FS)

Why Black Malleable iron products are special?
Before we go into details about Kirkpartick it is important to understand why their products are special. All Kirkpartick products are 100% British Made British made and take over six weeks to complete. Kirkpartick make their products from malleable iron, not cast iron. This is an important difference and should be understood. Cast iron is a superb medium for items such as brackets, knobs and other non moving parts. It is very strong under compression, such as when used as a bracket, but brittle under tension. Malleable iron is much stronger and less brittle under tension and this makes it excellent for thin items and moving parts such as hinges and gate latches.
Malleable iron is basically cast iron which has had an extra special heat process added to it during it’s production. This ‘annealing’ process gives the iron malleability (hence the name malleable iron). This makes the iron much stronger and gives it a slight elastic property which, unlike cast iron, stops it from being brittle. Stopping cast iron from being brittle has been a special technique used by Kirkpartick for 140 years. Because the iron is now malleable, component moving parts are now able to be hand riveted together giving a very much stronger joint which will never break. This cannot be done with cast iron because it is brittle and therefore runs the risk of breaking. Many cheap imported products which look the same as Kirkpatrick products are make from cast iron and the component parts are held together using cheap spring washers which will usually break at some point, we do not sell these cheaper products. Each and every product from Kirkpatrick is individually hand riveted (where required), this ensures outstanding quality which is unsurpassed anywhere.
Overall you can be confident when you buy a Kirpatrick product you are guaranteed to be purchasing a 100% British made British made product, made in the original foundry in Walsall, West Midlands, which has been hand finished in a process that takes over six weeks to complete and possessing a quality that is unsurpassable and will last you a lifetime. We are so confident in Kirkpartick products we offer a returns no quibble guarantee.

Kirkpatrick HistoryWilliam Kirkpatrick, Esq., J. P. (1817-1887). Founder, in the year 1855, of the business in Walsall, that was carried on for many years in his name and under his direction. His son, Vincent Kirkpatrick, succeeded his father and presided over the incorporation of the business as a Limited Company in 1901. Upon incorporation, many loyal and long serving employees were given a shareholding. This started a tradition which continues to this day. Many of the descendents of those first shareholders still retain their interest in the Company and the Kirkpatrick family still also retain a shareholding.

I Mak Siccar
The origin of “I mak siccar” forms a direct link with one of the most decisive events in Scotland’s history.
The defeat of Wallace by Edward 1 at Falkirk in 1298 was reputed to be due to the defection of the forces of John Comyn, Earl of Badenoch, to the English. After the capture and execution of Wallace in 1304, Comyn had ambitions of becoming King of Scotland himself. It was at the Monastery in Dumfries that Robert the Bruce, a strong supporter of Wallace, and Comyn came face to face. They quarreled. Comyn was stabbed by Bruce. Rushing out to his escorts Bruce told them, “I doubt I have slain Comyn.” Roger Kirkpatrick, saying “I mak siccar” (I’ll make certain) ran into the building and finding Comyn wounded but alive, stabbed him to the heart. Subsequently, Robert the Bruce was crowned King of Scotland in 1306.

SAMSUNG CSC..well on one side anyway …

SAMSUNG CSC … could just do with a bit more felt on and some tiles out of the plastic bags and onto the roof, may have to wait until after Christmas, but subsequent to the photo felted both sides now and the floor concreted.

PS

I received this kind comment by email from Terry in Wisconsin, the comments on my blog seem to be broken …

 

Richard,

Tried to leave a comment at your site, it wouldn’t allow but I wanted to let you know how entertaining your blog has been this year as it is winding down. Your new digs look grand and if it makes for better “green woodworking” you should have it. I am associated with a green wood group in Belgium, groenhoutatelier.blogspot.be who teach primarily from the Ename forest near Oudenaarde although I live in Wisconsin, long story. You may have met Chris Nuyens at the Bodgers Ball with little Alwin his son, he continues the work in Belgium while I muddle on here attempting to spread the green word.
So any way, I like your blog as your style and mine are a fair match, I am always searching for another way to be involved, to get my hands on, to research and delve into another project and to mingle with like people, that is often the best part.
Hope you and yours have a grand holiday season.

Later,
Terry Vetrono

Correction

Thanks to Richard Francis for pointing out the nonsense that had crept, unnoticed into my post “Meeting Peter Folansbee”.  I seem to have suggested that red oak wasn’t grown in New England.  This was due to a mini crash during the writing of the post which resulted in “in the UK” being missing from “Red oak isn’t grown much, except in arboreta.”

Sorry about sounding as though I don’t know what grows in the Eastern US (and mostly I don’t!)  But I do know that red oak is pretty common, but not as good as white oak – at least for some purposes (I’m sure it has it’s uses too.)

Must read even more carefully before pressing “publish”.

Starting to look like a seat.  The assembly is just a dry run with no holes drilled or pegs fixed, that will be done on site at East Riddlesden Hall.  I’m axing out the arms now, and then there’s just the arm supports to turn and the wings to shape, date to carve in crest rail, fancy up the moulding, pimp the ends of the seat slabs, and make sure the side rungs drive right home so the back is relaxed.  It is not relaxed in this photo, it is an unlaidback, unfinished chair.  At this stage it is dangerous and must be kept in a cage.
