Thread: Pond filter with UV lamp
30/04/2021 13:53:09

Thanks all for your quick!!

Steve thanks for reply... perhaps my wording was a little bit I am not saying you can get UV LED lamps for algae control....this is what I am looking for!

And if Jason hasn't heard of it ... its not looking as if they exist! Nigel is probably right that it needs some research, bacterial growth and things of a biological nature is the area I'm not that conversant with.. will have to ask at the fish shop...

Hi All, Tea Room again!

Replacing a fluorescent type UV tube with an LED.

The problem/s. ... I fitted an 80W solar panel on my shed roof to power a small 12v DC pond pump, it works great using the battery regulator supplied with the panel, however the ultra violet lamp used in the filter housing is 230v AC and I have rigged up a circuit (relay) to switch on the UV lamp only when the pond pump is being fed with power and water is then flowing over the UV lamp.

This also works a treat but it would be more efficient to use an LED UV light, (I assume), this would give me a completely free pumping and filtration setup using the solar panel.

The problem is that I don't know if the UV LED striplights have the same effect as the glass tube type lamps and there does not seem to be much information about these lamps, I have seen some led UV lamps for aquariums but these appear to be for growing plant conditions.

If anyone could give me advice about this it would be very much appreciated.

Thanks Peter,

yes I do agree with the fact that the website is more convienient than having to look all over the place for records, however my main complaint was about cancelling subscriptions, I too like yourself had cancelled once before, using exactly the same procedure as I did the last time, there should have been no dispute.

I did state that the company has a .com url, and you are correct in saying that it should be , it was peculiar that the lady who I spoke to had quite a pronounced American accent even though I selected the uk helpline on the web page.

Thanks Philip... will have a look.

Thanks to all for replies,

it is a good idea as ChrisH says to cancel any payments when terminating the subscription, I just wonder how many people are caught up in this scam.

I agree with John (modeng2000) there are other free sites which in my opinion give just as much information as paid sites, I have learn't my lesson with this one, I am indebted to TrustPilot for giving me an edge in the ensuing confrontation with hard faced 'helpline' staff....(I have no connection with TP) although some 100% reviews are a bit suspicious.

My other axe to grind is with Virgin Media who seem to treat customers as a commodity...but I will leave that for now in case my blood pressure goes off the scale....!

Hi All.... hope this is ok for the Tea Room..

I don't normaly get very annoyed but I was really miffed about ending my subscription with this company.

I paid a months subscription and cancelled the subscription a few days after I had looked for information, well within the imposed time limit.

I recieved on the webpage a cancellation advice note and a plea to think about what I would be missing out on, however I was not impressed with the sneaky way that relevant information is witheld unless further payments are made.

I would have thought that was it.... I didn't use the website again and forgot about it, to my surprise on my bank statement I noticed that the subscription had been taken again a month later!

I telephoned the customer helpline only to be told that I had not cancelled the subscription properly and should have noted the cancellation number and other details, also that it is company policy not to re-imburse any payments..... after a somewhat irate conversation I managed to secure a repayment.

If anyone uses Ancestry, be very carefull when cancelling your subscription, they hold all the cards and after looking at the reports on Trust Pilot it appears that others have had similar or worse problems.


Thread: What to do when you lose something
22/04/2021 15:33:21


If ever the gremlins steal something and hide it, the first thing to do is give the workshop a good tidy up...they don't like that and will put it in the place where it should have been in the first place.

...Thanks Jason... you are a star..!!

rgds Bob. (James)... its a Scottish thing..

04/04/2021 19:35:18

Thanks Jason....

I have done exactly what you said and the page to enter the subscriber numbers came up as you have shown above..........

the numbers are entered and the page 'saved'..

but there is still no access to the magazines, as I said previously, on clicking 'magazines' ... the next message states that I need to enter my subscriber numbers in my "menber profile" which is another page and does not have boxes for subscriber numbers.

Thanks again for your help.. rgds.Bob.

04/04/2021 18:28:31

I have subscribed to ME and MEW, but can't access the magazines as per Jasons instructions above.

The message I get is "this is subscriber content only..and I need to register my subscription number in my member profile" .... so I go to my member profile.. but there is no place to input my subscriber number ...!

If I log into Pocketmags I can access some magazines but not any of the previous subscription year.

What am I missing out ? would be gratefull for any help.


Thread: Digital Callipers - again

Hi Gary...

I had a very similar problem with the stainless steel calipers I bought with the logo 'Max Measure' probably Chinese, very often the reading would re-set to around 5.07mm for some reason when being adjusted.

I took it apart and gave it a good cleanup, but no improvement.

.... I changed the batteries a few times with no effect,

I thought they may have got damp so I left them on a radiator for an hour or so...but still the same.. so I thought to try another battery but I didn't have the right one which should hav e been an LR43 but I only had an LR44 which is a bit thicker but it fitted in, and is now ok, and 3 weeks on it is still ok.

Perhaps the LR44's are a higher voltage?

Thread: Coffee machine project
02/02/2021 17:23:54

Hi Ian...

I don't know about filling a coffee machine water tank but I was contemplating filling the toilet cistern from an outside rainwater tank, there are some 'off grid' people who have already done this sort of thing but you will have to look for them on the intnet...

I think it would be quite easy to fit a level indicator and an inlet valve system, perhaps an overflow for if it all goes to pot... or an alarm.


Thread: Telescope Mount: DIY Azimuth Bearing Suggestions?
18/01/2021 09:24:33

Hi Dr GMJN....

This may be helpful,

seems that after some experimentation that kitchen laminate was a good candidate.

I have made a vertical azimuth telescope bearing using the material that my wife has for doing oven cooked chips, I don't know the name of it but its a golden cloth type material, in my application it slides on a metal shaft however you can't glue it so it would have to be held in place at the edges for a Dob.


Thread: Wood boat hull
22/11/2020 15:49:16

Hi Bob...

I am making a model boat at the moment, this is 'Ravenna' and plans are from a well known supplier, disclaimer,

I didn't plan to make a boat but was in the process of changing a wooden slatted venetian blind when it ocurred to me that the wooden slats could be used for something.

The 'slats' are I believe Maple and I managed to bend most of them to shape using plenty of clamps.

'Planks' are butted up with plenty of good quality waterproof glue, small gaps filled in with expanding glue and when finished soaked in thinned paint then 4 coats of paint,...still not finished this ... but it looks ok having never had a go at a model boat before.

The cabin is now buit up and am making window frame inserts using brass 22mm compression olives which are elongated over a mandrel and silver soldered.

I don't know if this is the right way to go about it but I'm not one for convention...

Good luck Bob..

Absolutely brilliant....thanks. Bob.

Thread: Basic Harold Hall Rest movement
14/04/2020 19:50:53

Thanks Martin for giving H.H's updates to original design.

Adrian, as you can see I haven't followed H.H's design but used what bits I had in my junk box, the actual rest table and fittings sit on an old rotary milling fixture and this forms the 'slide' bit of the design, it works just as well.

I don't think you need to get the dovetail angles to exactly 30 degrees I should imagine any nearby angle will be ok so long as they are the same angle... in fact if I was making it, I would make the female part out of 3 pieces and screw them together, it saves having to have the right dovetail cutter and is not a part that needs to made for heavy work...the same goes for the male part of the slide.... is anyone going to inspect it afterwards?

You can even make the parts so that if the screw holes a elongated a bit you wouldn't have to have gib strips...nb..I am definately not a purist!

Hi Johan again... I should have inserted that it can have a function other than setting the top table rest horizontal.


14/04/2020 17:56:53

Hi Johan....

I have also made Harold Halls grinding rest and I too wondered what the left & right tilt was used for, but I had made it by then !.... after much head scratching I couldn't understand what use it would be and it wasn't until I saw a Quorn in action that I realised it did have a function and was a necessary item.

The tilt can be used to 'wipe' a cutting tool over the grinding wheel in order to limit the striations that a stationary grind would create, you need to set the top of the rest parallell with the wheel for this, unfortunately since I found this little operation was available to me I have not had chance to try it out as yet.!

Here is my rendition of H.H's grinding rest mounted on an old lathe bed...I must say the rest works great.




Thread: What Did You Do Today 2020
04/04/2020 20:02:20

Nice work John...

I made this fitting for the lathe so I can set the 4 jaw chuck up with the dti when working with small diameter stuff, I have a magnetic base with the dti on its arm and find it difficult sometimes to get the needle to be at the top of the small diameter piece.

I fixed an old microscope rack & pinion slide on the arm holding the dti and now the dti can be moved back and forth easily over the work piece after the magnetic base is set in the general position.

Its now nice and easy to set up...Bob


Thread: DTI base
02/04/2020 20:40:11

I was having difficulties in setting the dti when small diameter work was being set in the 4 jaw chuck, the problem being that the needle of the dti needs to be moved only tiny amount to set it on the top of the work. The jaws can then be aligned, usually I move the magnetic base about and with a bit of luck just get it takes some small but annoying faffing about......but no more!

I have fitted the base arm with a microscope slide which holds the arm with the dti fitted, the mag base is put in the general area and the fine adjustment is made with the microscope focussing slide... is it over the top?... yes... does it work better than before ...yes.
