|Thread: Sewage dumping|
Umm no Duncan, if one outflow is opened for say 100 hours in a year and there are say 100 outflows then that is 10,000 hours of sewage, now the river Wye is one of the longest river in the UK so you see how the maths work and how the total can add up.
I don't know about your area but surface water, in the main, is separate to sewage here, the exception being where roof runoff at the rear of old houses do enter the sewage system.

The River Wye was in the news last week because the phosphate levels are waaaay over the legal limits and while land runoff from chicken farms poo being spread over fields near the river or tributaries the water company dumped raw sewage for 40,000 hours in 12 months!!!
It's a shame as we had otters coming back into the area and a couple of pairs of Kingfishers but with the minnows dying from the pollution we will lose them, also salmon caught in the river is down to low double figures this year.
Welsh Water are now saying they are 'looking into the issue' (probably because the issue has been highlighted). Before anyone says about profit, WW is a not for profit company.
It's such a shame to see the river deteriorate so much over my 70 years here.
|Thread: Antikythera Mechanism|
My random 2P's worth:
They knew about gears and ratios at that time so could they have made some kind of 'rotary table' out of the parts they had already made?
Tin hat now on
|Thread: Warco GH Universal mill help|
The mill actually weighs in at 360kgs and the head is the heaviest part of the mill so while it's an estimate I don't think I'm that far off. If the mill had a rack for the head I would go with a counterbalance but it has a screw in the column and takes 3 1/2 turns of the handle to move 10 mm! The effort to move the head down is appreciable while not as much as going up.
A freshly charge battery in my drill will move the head up but is on the cusp of the ratchet triggering to avoid motor burnout etc.
I think I'll look for a mobility motor or similar and build on from there, meanwhile I'll use the cordless drill as I have 3 batteries so always have fresh ones available.
There's no easy way for a counter balance and I think it would need to offset about a 100kgs to work. I don't need variable speed just need it to go up and down at a suitable rate, I have a couple of leisure batteries left over from my touring days so a buggy motor would be worth looking into.
I've recently acquired a Warco GH Universal mill and it's a great mill but the method for raising the head is rather laborious and long winded!!! I tried a 3nm stepper motor but it couldn't touch it, so I then tried my 18v drill and it did move it once fully up and down but now the ratchet in drill mode has kicked in and no longer works.
Has anyone done this 'upgrade' or got any suggestions?
|Thread: Grubby Screws!|
I've decided to drill out and thread for M8 rather than mess around with making some that would have an inherent weakness of a slotted head.
Thanks for all your advice chaps.
I have a couple of holes threaded ME 1/4" x 32, I thought I had some grub screws to fit but apparently not, the ones in my tub marked as 1/4 by 32 are too small, duh!
What size grub screws do I look for, 10-32?
|Thread: LPG Gas jet sizing|
Not sure how much exploring you did but if you had scrolled down to the bottom of the page you would have seen a link to the page you need - gas essentials and jets
|Thread: Need some help/advice|
I'm starting to set up my new to me mill, it has a table size of 800 x 240mm. I currently have a small 'toolmakers' vice with 3" x 4" jaw opening, I want to get a mill vice to fit on the table but don't really know what size to go for, 5" or 6" with the commensurate overhang or keep to a vice that stays within the boundaries of the table.

My first Duplicate!

Think this is the one?
Electric cars are promoted as lower maintenance costs but where is the cost of battery replacement factored in as I can't believe they would last the vehicles life and would there be a tail-off of performance as the batteries reach end-of-life?
And would the recycling/refurbishment of batteries be completely green?

m-machine.co.uk sell it and I've always had good service from them.
|Thread: NEW SCAM|
Just received a text from Parcelforce @ 09:37 saying they missed us earlier and to book a redelivery via a link.
The link 'looks' valid but I went straight on to the Parcelforce website and entered the 'tracking number' manually and guess what? It's not a valid number.
I entered the mobile number 077750 99726 into a valid mobile search (there are a number of sites that come up as not tested by Norton) and it is located in Indonesia.
If you're a person expecting a delivery you could be easily taken in by this one.
|Thread: Newbit Londoner|
Expect to spend a fair bit on tooling and accessories to kit your new lathe.
What are you thinking of building?
You'll get plenty of help and advice here
|Thread: 2-Part Covid Vaccinations|
My wife and I were contacted by our respective surgeries by phone for our jabs and had them last Friday and the Friday before, we're 69 & 70. Missus had quite bad reactions, myself not so bad, to the Tizer vaccine.
|Thread: Tools and equipment loan list/surplus list|
Chris, thanks for the offer, close-ish but not close enough, it's for a Denham Junior mkll faceplate or rather one that nearly almost fits, most frustrating
I agree, a brilliant idea, one thing worrying me though Chris, if you're 77 this year you were born in 1944! Or should another 100 years be added? Yes depends on how you read it.
I could do with borrowing a right hand 1.75" x 6 t.p.i. tap to rethread a faceplate I possess if there's such a thing.
