Still for sale. We walked past yesterday evening. Though the M6 is overhead the elevation is insufficient to hide much noise. It’s really incessant and quite deafening. Shame as otherwise with its layout and paddock it would be very pleasant.There is a brook that flows through with an overspill feeding it from the canal too.
Lovely house, but I agree the noise there is terrible.

If there is an accumulator there will normally be a delay in the pump starting after opening a tap. Increasing the flow resistance with filters will reduce the flow from the tap and consequently increase the time taken to get to the pump cut in pressure. If the flow is adequate it would not seem to be a problem, However 12V pumps that are typically used are not designed with filtration systems in mind so problems may well ensue, especially as the filters foul (and on canal water that would seem likely). If further filtration/water purification is added (as suggested in the OP) then greater problems may well arise with water flow rates if a single pump is used to push water through the whole system

Grants lock cottage for sale, again.
https://auctions.savills.co.uk/auctions/8--9-may-2024-149/grants-lock-twyford-banbury-ox17-3jw-9835
I do not see that being a worthwhile purchase at the price and with the additional issue of the access charge.

Best wishes for the Hip operation.

Re the 10 or 11 thou exhaust clearance, the smaller value was in the earlier manuals and 11 thou in the later versions. I doubt the difference will be of any import. I set ours to 10 thou as that is what is cast into the rocker cover, the engine is circa 1960, the later version of the manual is from (I think) 73.

0.254mm = 1/100 inch or 10 thou?
I agree but it is still the wrong dimension, should be 5 thou inlet and 11 thou exhaust according to the manual.

And these are the torque settings, but note they are in pound-inches not pound-feet
And the head should be tightened like this.

I suggest following the instructions in the Gardner manual valve clearances.pdf
If you need a manual PM me

The blue item in the far bottom left of the photo looks like a diode splitter, if so that needs to be included when drawing the schematic. Also if only one battery is now installed, how has it been connected (so looking at the photo of the original setup may be a distraction?}.

A regular visit to The Crow locks on the BCNS provides a nice coating of oily tar on the surface of the Hull (though probably dissolves any bitumen blacking at the same time). One of the most polluted sections of canal that we have been to.

There are videos on coal gas manufacture on Youtube. The first one below gives some idea of the byproducts that were collected/made and is thus relevant to the tanker trade (the sound is terrible but just about intelligible). The second gives a more hands on view of the actual gas making.

Gas water was also derived from the coke. After it left the ovens the coke was red hot and, in air, would start to burn. So the coke was quenched with water. Some water turned to steam, which, with some coke, might be fed back into the gas producers, but as the coke cooled, there was a lot of water contaminated with products that could be extracted and sold.
A Gasworks wasted nothing.

I agree that water was used to quench the coke, however, my recollection is that the raw gas was passed through water to remove the denser components and reduce the smell. The result would be water saturated with oils, creosote, ammonia etc. This was a valuable source of chemicals and was thus collected and transported to chemical processing works for extraction of useful chemicals

Our Gardner 3LW came from a Smiths crawler crane. Apparently they had two engines, one for the caterpillar tracks and one for the winch, ours being the track engine. No idea what type the other engine was.

Try agricultural merchants like TFM if you want Golden Film and buy 20L rather than 5 (you will use it). Golden Film commands a premium price from many suppliers (morris included if you order direct)
Alternatively try Smith and Allan or Westway Oils, look for oils which are both SAE30 and API CC (thus a low detergent oil like Golden Film), plenty of listings on eBay and these will include delivery.

Try Wet and Forget, it's a biocide. Follow instructions, do not drink, do not pour in canal, etc etc

In an attempt to stop this C&RT are attempting to capture what a canals standard gate should be and record it in their CAD system. I am attempting to get these drawing made public. They require this given that they are moving to CNC manufacture of lock gates. The new head gate which have just been install this winter on 'hampton were machined in 47 minutes on a CNC machine, rather than taking 3days to do on the machines currently installed at Bradley.
It then took the same 2 days to assemble the gate.Given this the BCNS and the NAG have agreed with C&RT what a standard BCN gate should be, and a set of drawing have been produced. If you would like a copy I will attempt to procure you a set.
I am curious about the standardised design for BCN gates. Does it utilise a frame faced with planks as shown in your coloured drawing or is it constructed in the current style with thick timbers placed side by side and held together with long transverse bolts? A couple of years ago I have a long conversation with a CRT guy who explained to me that the modern style tend to bow under water pressure as they age and this causes the paddles to stick in their frames. I would appreciate a look at the new design if that is possible.

Just use the oil from Westway, it is the spec you originally asked for.
-
This supplier provides 15W40 in API CC. I have used oil from this supplier before and it's been fine, though I have not used this particular oil as I need a straight SAE30. The price includes delivery.
PS The company is adjacent to the Staff and Worcs canal in Wombourne

Recently when we were doing the offside veg cutting we had one of CRT's ecology persons tag along with us for the day. It was a nightmare because they kept saying you can't cut this, you can't cut that, even in parts where trees were causing a major problem, not just to navigation but also where they were compromising the safety of boaters too.
On the Bradley Canal restoration there is a large tree with three trunks below the lowest lock. The tree sits in the bed of the canal where the bywash used to emerge. The CRT ecologist will not allow us to remove it even though it's in the bed of the canal. D'Oh!

I also wonder how far the (very) modern trend to allowing vegetation to decorate canals banks is a factor. Many pictures from some time back show canals very shorn of trees and undergrowth. I also am aware that there seems to be two schools of thought: keep them clear to avoid storm damage when trees are brought down, the other that growth helps to bind the soil together and reduce erosion. I don't know enough to assess the balance. The current 'political' context favours greenery at any price - sometimes the longer term cost is now being shown to be greater.
But I speculate.
The trees do seem like a big risk to me. They add a lot of weight, but also catch the wind and then topple and collapse. Sadly, allowing unrestricted tree growth is very much the norm on cuttings for roads and motorways these days. Consequently I suspect more incidents will result. Having said that, I fully agree that the Easenhall cutting looks to be too steep an angle given that the soil appears to be soft throughout the depth of the cut.

From the details :
The property was originally a former lock cottage on the Staffordshire and Worcestershire canal. It has been substantially extended and over the years to form the current house. Internally there are some original parts with timber frame work still visible internally. The property offers lots of opportunities for not only family living but scope for multi-generational living and ample opportunity to work from home.
Maybe the lockie had to 'walk to work.
AFAIK the S&W cottage were not timber framed but all brick. I still doubt this is a lock cottage.

Surely you'd want to copy the design of a lock that hasn't collapsed! Otherwise it is only an insight in how not to do it. 😀
I think my suggestion is largely valid, though I accept your argument. Abandoned locks may only have collapsed due to decades of dereliction and zero maintenance and thus this does not necessarily negate the value of the original design. Also I suspect there are some part demolished locks (or photos of them in a part deconstructed state) which will also give an indication of the designs used.

You obviously didn't check before typing that
Can't find one on RS either. Never heard of Zoro until now and they have an open-ended but no combination, so that will do. Thanks for that!
So what's this- F'ing scotch mist? Perhaps you should engage brain before letting clutch out on keyboard! Just search BA spanner in RS

I lost my 2BA combination spanner the other day and to my surprise, was unable to find another for sale on the net, anywhere! Are BA nuts and bolts really that obsolete?
BA spanners are available, Zoro, RS, Amazon and of course eBay have them. RDG tools have some open ended spanner sets which look ok and they have BA socket sets . Quality spanners from named suppliers are becoming quite expensive (ELORA etc). I am not sure you will find combination spanners. Nuts and bolts are available from model engineering suppliers but again the low demand causes prices to be much higher than equivalent size metric fasteners. Taps and dies are available from model engineering suppliers.

The glass in ours was scratched like that for years and did not fail. This year I have bought replacement glass from local glazing company and fitted it, so the old glass is held as spares.
