|Thread: NHS Covid Passport Scam|
there is the real NHS app that allows you to order repeat prerscriptions and view when you had your vaccinations and show a QR code. no charge no credit cards involved
|Thread: Centec 2B - New arrival and Q&A|
I would just get the Arc Euro MT to J6 and make a drawbar from M10 threaded rod. I have mm whit and UNC in two sizes of drawbars for mine as if I see tooling at a good price a Drawbar is cheaper than some other tooling.
B16 is one of a series of European Tapers used on chucks if you search MT3 B16 in Google you should see lots of possible suppliers, I have used Amazon in the past.
|Thread: Oxy Propane kit|
CuP alloys do a nice kit.
How big a burner are you using?
|Thread: Something a bit different- excavator arm|
The chap who did the walking one did a tracked one before, he used to be at Harogate most years.
|Thread: Help to value a Schaublin lathe.|
I sold one some years ago, Expect 4-500 pounds, more if with good selection of collets or optional slides.
This is a instrument makers lath so will not have many of the features some are talking about.
Ebay or similar with a reserve will probably find the best offer.
|Thread: Washers under nuts|
I suspect that washers every where came from working on costs plus jobs for the MOD in the cold war where if you added washers everywhere on thousands of bits of kit and got cost plus profit it would add up.
Reason for this is everyone iIhave met that worked for GEC, Marconi, BAC etc wants washers every where, and when asked why because there supervisor or manager insisted, never have got a good explanation.
Commercial people I have worked with only wanted them if to cover slots or protect paint etc.
|Thread: What nut and bolt material?|
This are of corrosion is complex. A good guide is the PRE no which is a guide to pitting and crevice corrosion resistance
As a guide
304stst is about 18
316stst is about 24 so 30% better but if at elevated temperatures would not be considered marine.
Generally if there was a problem on a swimming pool or sea water I would look for a PRE >40
This takes us to super Duplex such as SAF2507 or 254SMO which is like 316 but with more chrome and molly.
|Thread: Taper-Lock Bushes - tolerances|
h9 is clearly the intended shaft tolerance, I suspect the numerical tolerance is the range over which the taper locks should work
holding the h9 Will probably make removal easier if needed
The h9 tolerance I quoted is out the Fenner download. either way h9 or h8 top limit is 48.000
If you don't want to wedge open the the taper-lock the shaft should be h9 giving 47.94 to 48.00 so your shaft is a smidgen oversize.
Turn it down or open out with screwdriver.
|Thread: Hemingway Kits filing Machine|
Nice build log, keep it coming please.
|Thread: Electric vehicles|
Its going to happen, see the news the other day that BMW are moving all combustion engine manufacturer out of Germany and retooling for doing the electric power packs in Germany. The report suggested so the German workers were protected for the long term.
|Thread: Multifix toolholder Vendors|
I started with the create which was fine, then bought some more holders from Germany via Ebay and they fit pefectly, Paints a different colour but they were quicker and no carrier customs fee.
Using a genuine Dickinson that came with the lathe I occasionally got a Jam when parting, with the multifix straight through under power feed including 304/316 stainless steel.
|Thread: Hand drilling stainless steel 3mm thick|
Its Hard work but not this hard.
Need an old fashioned corded drill with two speed gear box. trigger control helps more.
use good drills Dormer A002 work well, they are like a split point multi facet, use cutting fluid like Rocol or CT90.
I was doing M10 Tapping size in 316L 10mm thick. 4 holes per plate 8 Plates, took an afternoon to drill and tap, used two sizes of drill 5 mm and tapping size. Hard work but keep the pressure on and change the bit as soon as it starts to rub.
|Thread: Parcelforce or DPD|
DPD every time as they will leave in a safe place. easier than going to he sorting office to collect parcelforce.
|Thread: Hydrogen-powered train makes UK maiden journey|
Peak generation and distribution Capacity is near 50GW, averahe use is 32GW and mininum draw <20GW so as long as cars are charged off peah there is a lot of capacity,.
The use of smart meters will allow for more management of who charges when, and faster charging stations are appearing at petrol stations now,
I filled in online survey with one of the fuel majors where I pay at the pump and they clearly see themselves as an Energy company, watch to see how much some of them shift to renewables.
|Thread: Stainless steel|
+1 Done the same been using it 2 or 3 years of fairly heavy B&W use and only on second bottle of ink.
|Thread: Is This a Tooth?|
Longest Dinosaurs tooth 300mm / 12"
|Thread: Warco WM280V-F Gearbox|
One of the interesting things with Barrys stripdown of the gearbox was the the O ring grooves, as the dimensions were decidly odd Barry sent me the dimensions and asked for my view on the circlips to use.
The dimensions were:-
Shaft :19mm Groove 18.5mm Width 1.3mm old circlip 1.0mm thick
The only one that is std that I could see is the 18/17 and that was after checking the imperial ones as well.
In the end I sugested the following sizes and comments.
Well all I can say is what a dogs dinner
If they don't look as if they will stay In place make a tapered mandrel out of steel
Hopfully now that everything is sliding properly the circlips will stay in place.
