PPS: Wealden have revamped their site a bit, so here's a direct link to Wealden's Ron Fox videos. Enjoy!

["crossed in the post" with Marcros - quite agree with him!] you have to wonder if he's bent the shaft of his router! You'll get a lot of recommendations for Wealden, who are excellent. In my limited experience, Trend's professional stuff is good, but Wealden and Axminster are slightly...

Do appearances matter, or is this just 'to get you there'? Copper with SS or Chrome ought to be OK - so can you use conventional plumbing fittings and silver solder (AKA braze) them, or possibly just solder them? Lead-free solder melts at around 200 deg C (it does depend on the type tho), and...

Small rollers: IIRC they're a 6mm spindle. So after a good rinse, I fit a 6mm drill in my cordless. take them in the back lane and spin them up to get rid of the last vestiges of paint. It works a treat, and they get re-used several times, which is good as the hairy ones usually shed...

Check the rotating magnet first. That repair is almost free!

I got my wife her second set of Pentax bins (9x28) recently. The first ones were a "pocket" pair, 9x15, I think (the label came off years ago) and are about 37 years old (bought as a birthday present for her when we were courting), and all the rubber covering had come off in sticky lumps... but...

You really don't/shouldn't need that (you do at the top end, because of the individual aerial impedances interfering with each other). At the bottom, the input stage of each receiver device should filter as necessary, using only what it needs and ignoring the other signals. A cheap resistive...

Yup, I realised once I twigged it wasn't a thermocouple (what a twerp - still don't know where that came from - I do remember testing it on the kitchen table though...). Will read the article but I assume the other pair are shorted at the sensor and used on the other side of a Wheatstone bridge...

I don't see why - the same signal can go to any/all the receivers without any issues (well, as long as they are properly designed). You will need to ensure correct termination though, which requires a passive splitter or a distribution amp. In the case of the splitter (and some designs of amp...

I have just found the documentation for our system - Googling indicates that they are actually Platinum Resistance Thermometers (PT-1000). The installation guide talks about extending the cables (using co-ax, which might explain the phono plugs!). There doesn't seem to be any calibration...

@Doug71: Yup, the simplest thing is just a run of coax. Otherwise one of those dongles that includes the Freeview channels, but I'd guess they need subscriptions. ----------------------------------------------------- On WiFi speed: I've just put in Ubiquiti 802.11ac Wave 2 Nano HD APs with a...

I'm refurbishing our solar heating system (oh the joys of lockdown!), and I would like to neaten-up the thermocouple wiring. The annoying bit goes up to the sensor on the roof. The cable is far too long, and a lot of it is in a (literally) tacky coil "secured" to a rafter with insulating tape...

I have a lot of analogue kit, some of which is rather unusual, and for me it's very useful. If you only have digital stuff, there's little reason to use CoAx, I can see. But anything coming off an aerial will need it, so it depends. The other thing I will readily concede is that stuff using...

No losses because of the multiplexing (signals sharing one cable) - each has its own frequency band and they don't really interact. You will get signal loss from distance (especially with the higher frequency ones such as satellite), and incorrect termination... ... What does cause issues...

Wot 'ee said above. I'm just preparing to run in extra cabling, including more co-ax. Like Pete I have a distribution amplifier in the loft, which has the ability to combine a number of signals* into one cable. That makes the other end(s) neater. E. *Satellite, UHF TV ("Freeview"), VHF...

Hi Roger, I think Mac OS is (was) based on Berkley (BSD) which is similar to Linux, (both were intended for Intel processors), but not quite the "big" Unixes of old. The DC uses Safari on her (last year's model) iPad, and I find it slow and clunky. That said, there are a number of sites out...

Notable that my Trend T11 came with a guide bush alignment jig for the standard 30mm bush, and their universal baseplate came with the pin Phil linked to, albeit in plastic (perfectly OK for the task). One thing I find occasionally useful is a length of ground silver steel bar, 1/2" or 1/4"...

Sorry I came too late to this , but just in case someone else comes across this with the same problem, I have struggled with mine in the past, but now have a really easy answer: The issue with the SIP wheels on mine are the way the bearings are located: normally you'd expect a pair of...

NHS England isn't doing a good impression of having found any clues recently. Most of the innovation has come from the local teams right up against it. My wife's practice has had several cases amongst the medical staff, all of whom have been mild and they have apparently recovered and are back...

Ah, systematic experimentation - way to go, that man! It's interesting that my old router plate was an Axminster one, with holes tapped to take their box joint system. I never bought it, but IIRC, it had a hard plastic backer board/fence, something like Tufnol, or the Bakelite that many router...
