Nice set of "T" hinges, true wrought iron from the the late 19th century. More trickier than one thinks to forge
Interesting relationship I just realized. It's not overly strong, but so long as your hinges aren't warped, they shouldn't flop around too much. Just one more reason to shoot the guy who decided to stop producing these hinges.
Apologies for the picture quality. I didn't have very good lighting for this shot.

The site is on a plateau above Cwm Pennant on the shoulders of Garnedd Goch (700m) - one of the mountains forming the Nantlle Ridge. Records of mining exist from a prospectus issued in 1850 but the enterprise was in liquidation by 1894 after which no further work was done. Fortunately the scrapman must have considered the Cwm Ciprwth site too remote to bother with, which could account for the survival of the waterwheel and other artifacts. The site was extensively restored some years ago by the Welsh Development Agency and Snowdonia National Park. Since then time has taken it's toll and the two long flat rods have now (July 2011) snapped.
It seems likely that the mine operated in conjunction with Gilfach, passed on the way up to Cwm Ciprwth, and that all ore, etc passed out through the Gilfach adits. The evidence of mining on the site consists of 2 flooded vertical shafts and a horizontal, also flooded, adit. There is an almost complete lack of mining waste or scree which seems to mean that Cwm Ciprwth was no more than a pumping and access site for Gilfach.
The most notable feature at Cwm Ciprwth is the water wheel. This is complete except for the metal buckets and leat. The leat can be traced on the hillside behind but the final section, consisting of presumably a wooden launder, is absent. The water wheel was made by Dingey and Son of Truro, whose name appears several times on the metalwork. Diameter is about 25 feet and it would date from the mid 19th century. Presumably the wheel arrived at Cwm Ciprwth as a kit of parts as access by anything larger than a horse would seem impossible.
The water wheel drove a pump and a winding drum. The wheel drove the pump by means of three flat rods. These are long pieces of straight timber raised above the ground. It should be borne in mind that because the flat rods are not under tension they have bowed somewhat with age. The supports where the flat rods joined each other are hinged at ground level. As the water wheel turned the whole length of the flat rods would move backwards then forwards. This movement was transferred to the pump, which is also hinged at the bottom. The water in the drainage shaft was sucked up by the pump and fed into a channel and then into the stream which flows through the site. At the other end of the pumping mechanism is a counterweight - a box filled with rubble. The winding mechanism on the water wheel consists of a drum operated by a large gear wheel. To engage the drum there is a clutch, although the handle to operate this has been broken off. Presumably the winding mechanism would have been used to access the two flooded vertical shafts, in which case a simple form of pit head gear would have been present.
There are two stone buildings on the site, one consisting of three rooms. This may have been a smithy, storeroom or miners barracks. The other is a simple square structure next to the stream, possibly an explosives store.

We saw our first worn out set of bearings on a Brompton this winter. Nick's rear triangle was a bit shakey side-to-side, so new bearing to the rescue. This beautifully made reamer along with a knowledgeable toolmaster will make things good as new.
Nick was patient with us and knew the job would be done well. The next Brommie that needs a hinge bearing will be quick as we now have the tools and the parts.

It was on this day of photography that I was approached for the first time by someone who had a possible objection to my actions. As I was wandering round the small industrial estate on a Sunday afternoon, I was almost satisfied with the pictures I had taken so far. Shortly after taking a photo and walking back towards a road, a black 4x4 drove up the road towards me; I presumed they were perhaps asking for direction. It turned out to be the estate's security patrol officer who had been alerted by some of the units who had seen me on CCTV. He questioned me about the photos I was taking and I simply responded that I was interested in the colour and shapes the buildings had to offer, and being the open soul I am, offered to show him the photos. He wasn't bothered, but seemed satisfied that I wasn't there to scout out the security. "In that case I had better cancel the Police then. he said. I thought that was a good idea.
I wish I was good enough to get the mouth to open on a hinge, instead it is a simple part substitution where you slide out the closed mouth and slide in the open
The old pin and hold-open roller were removed using a dremel with a cutoff wheel to cut their tabs and then tapped out with a hammer.
Note how the new hold open roller will bolt into place...
(--upper left image)
Parts were stripped to bare metal, primed, and painted.
Before painting, I had masked the holes where the bushings and hinge pins go in, the hold open roller, and the hinge pin where it would ride in the bushings.
No need to clog the bushings with new paint and make the pin harder to insert.
Note the position of the bushings and where the masking tape was on various parts...
(--upper right image)
The bronze bushings were pressed into place using a vice. Old socks worked great for protecting the new paint.
(--lower left image)
I should have masked the hold open cam where it rides on the roller, but I forgot. I used a razor blade to carefully scrape off the paint to keep it from contaminating the cam and roller.
Here came SNAFU #1!
A painted hinge pin will NOT insert, even with a thin layer of paint. I had to use another unpainted pin. The two parts were mated and the hinge pin carefully inserted.
The paint was protected with a cloth and the bottom pin area was supported with a socket. I tapped in the pin with a hammer. Actually, it was more of a severe beating… Another reason to assemble before painting.
The hold-open spring was put into position, the detent cam pulled back with channel lock pliers wrapped in cloth, and the hold open roller unit dropped home.
(lower right image)
This inserted easily even after being painted. The cam was released and the roller unit secured with its Allen head bolt.
The unpainted hinge pin was carefully painted and the assembled hinges were set away for the paint to cure…
Lesson learned – install the bushings and hinge pin before paint – it is much easier to do and there is less risk in damaging the paint during assembly.
Lastly, the bolts needed resto.

A desperate, but successful fix to the old Sony Vaio laptop. I have simply soldered the broken hinge in place. With a large enough bead of solder (filling all available space), it will hold just fine -- perhaps better than a new hinge.
The poor thing is 8 years old now, but its kind is still loved by many, as I can tell from perpetual replacement hinge and battery offers on eBay.
