Ideal Standard quality failure Feburary 2026

After a few issues with fresh water leaking through one of the house loos I decided to replace the whole thing with something new. All turned into a bit of an epic fail on the part of Ideal Standard



As soon as the replacement pan arrived it could be seen that the exit pipe was neither round or consistant to make a good joint with the house waste pipe. 



The exit pipe is supposed to be 105mm diameter but was ± 5mm out. This template shows the gaps that would have caused a poor seal with the exit pipe.


The supplier was contacted who sent over a replacement but that replacement also had the same faults. Both were returned for a refund. I sent some photos to the manufactorer who said not to install the item and return it to base.

To see if this was a one off or a more prevelant problem I went and shoved my hand & camera up the waste pipes in a local bathroom showroom. Whilst it was not possible to measure for ovalness the toilet pans on show they did have poorly crafted exit pipes. An interior rim round the exit pipes was aparent which in service could have caused blockages and poor flow. These were also Ideal Standard brand loos. 

It's all very well looking nice but you also have to check the functioning parts of everything bought these days.

MR2 Drivers Club Social Survey results March 2026

 


 A short Google Forms survey was circulated to members of the South West region of the UK MR2 Drivers Club early in 2026.  This was followed up with a wider distribution of the form link to other MR2DC members. The result 35 responces are presented here :

Forms response chart. Question title: MR2 type that you have and drive  (Tick all that apply). Number of responses: 35 responses.

Forms response chart. Question title: My main MR2 is .... Number of responses: 32 responses.

50% indicated that there MR2 just for weekends and special occasions. 15% being restored and 12% as a daily driver.

Forms response chart. Question title: Area of MR2 activity ( not all areas have coordinators ATM ). Number of responses: 35 responses.

The 60% Slice is the South West.

Q: How far would you travel to a club event ( apart from National Day ) ?

A: Most respondants indicated about an hours Drive ( 50 .. 60 Miles ) with about 4 indicating 100 miles or 2 hours would be OK.  A couple indicated that 1/2 counties over would work.

Forms response chart. Question title: Which of the following events have you attended in the last 2 years. ( Tick all that apply ). Number of responses: 30 responses.

Forms response chart. Question title: What events would you like to do more of in 2026 and beyond. Number of responses: 34 responses.

Q: Other car club affiliations. Are you a member of another car club or group, if so what ?

A: 32 % belonged to no other group.  With 4/36  folks belonging to other MR2 related groups

No touch record turntables *update*



I had one of those cascading thoughts streams yesterday, It would be great to have a record turntable that did not have a stylus. The music grove would be read optically and translated into the music stream on the fly. There would be much less wear on the record and the signal could be manipulated to remove any distortions.

After about 30 min I had some ideas sketched out. First the name would be C&P audio using the initials of me and best audiophile friend :-)  The cartridge could be linear tracked like my fav B&O deck hovering just above the plane of the record surface.  The detector signal could be fed to a small processor below the play deck for interpretation. A few of ideas rapidly followed ..

  • Speed of track optical processing is well within the scope of modern processors (like self driving cars)
  • Lighting and video capture via optical link to head (like an endoscope)
  • Track detection and linier tracking across record - controlled by feedback from the cartridge (like a 3D printer)
  • Surface height tracking possible over warped records
  • Scratch detection and skipping, long view, short view
  • Digital or analog output
  • A dust removal system would be needed to replace the stylus pushing debris out the way either by blower or electrostatic.

Then of course I had to Google the idea to find what else is out there .... Looks like only one vendor ELP Laser in Japan has the pure light/laser version I was thinking about. Two other vendors offer cartridges with optical movement interpretation. The Minot has a full deck with optical tracking and arm movement, with DS Audio offering a cartridge than can be deployed on a tradional deck with replaced signal electronics.

Key Technologies for Optical Playback
  • ELP Laser Turntable: The most prominent, and essentially only, commercially available option is the ELP Laser Turntable. It uses lasers to read the groove modulation and converts the reflected light directly into an analog signal. It is fully contact-free, meaning no damage is caused to the record, allowing for high-fidelity sound from worn vinyl. Being a made to order unit the cost is high. 



  • Miniot Wheel 3: This modern, minimalist, and versatile player also features an optical pickup system rather than traditional magnetic coils. It uses a stylus to scan the groove but has optical transducers to create the signal. Claiming to be gentler on records while providing a "perfect" analog sound from 0 Hz.
  •  


  • DS Audio Optical Cartridges: A different approach, DS Audio produces optical cartridges that can be installed on traditional high-end turntables. They use an LED light and a photo-sensor to detect the movements of the stylus, rather than magnets, which they claim reduces noise and improves tracking.


Given the available technology of arm tracking control from a 3D printer and improved speed of processing available in a Pi 5 there could be room for a cheaper all optical turntable. The development costs and effort would however be substantial. Probably stick with the B&O deck for now. 





Down this internet rathole technolgy based search came across this interesting items about dust repelling surfaces research at NASA. 

Update 5/4/2026

Some ideas just won't let go, here are some more notes on the subject. 

How fast would you have to read a record groove at normal playing speed ? The answer depends on where on the record the needle is. As rotation is constant, at the outter edge the needle has to move faster than in inner part of the record to maintain the contant RPM. When it get to the run-out area, next to the lable, the circumference is smaller therefore the needle is moving slower in the grove to maintain the same rpm.

On the outer edge of a LP playing at 33 rpm the needle travles about 0.5 meters per second. At the inner edge of the same LP the needle is moving at 0.2 meters per second. The range of speed is less for a '45 but within the same scale.



Using a small handheld USB microscope camera we can see some images of a '45 revealing scale of the optical issue.

The project would need better optics to have a chance to read the groves at a reasonable level of accuracy. Also the tracking of grooves would need to be +/- 0.1 mm. 

It might be possible to scan a field of group of grooves for a revolution and stitch the tracks together in sequence to recreate the whole track. However if the groves were missalligned or stiched out of order, the result would sound like a scratch.

How Do Different Play Speeds Affect the sound of Vinyl Records?

There are two important parameters that affect the sound quality of a record which are both set when the record is cut. Firstly the speed and secondly the gap between the grooves which is determined by the playing time. In simple terms the higher speed of 45rpm provides better sound quality than 33rpm as there is a longer section of the groove to hold each second of audio. This is analogous to the sample rate of digital audio. But it's not that simple! The outer edge of a 12" record travels at more than twice the speed of the runout groove near the label so in theory the audio quality is gradually decreasing as the record is playing.

Equally as important is the space between the grooves. The louder a source recording and the more bass the greater the lateral vibration of the cutting needle and hence the width of the groove itself. It is possble to extend the playing time by reducing the volume and attenuating the bass but this reduces the quality.

The 45rpm 12" single developed in the 70's would often have only one track per side and made the most of vinyl limitations to get the maximum dynamics and quality available. Ultimately the standard 12" LP album at 33rpm is a compromise between sound quality and the playing time.
