Thread: T nut slot channel

I suggest you go to the "8020inc" store on ebay to find your extrusion and then look closer to home. Nathan.

It looks like the link provided by MichaelG is for end supported loads given that they show a deflection. In practice, Unistrut provides support for much greater weights, given that you fix to horizontal substrate (ceiling) or vertical substrate (wall), at the correct fixing spacing. In a concrete building (modern Hospital) , I'm happy for suspension of 200mm/8" heating main to be suspended from Unistrut at 1Mtr centre. In reply to postings as to the nut fixing, it is not a tee nut, it is a Cam nut which aligns two slots/grooves to the rail therefore applying both inward and downward pressure as the fixing screw is tightened. Nathan.

I should have said that it can take some time to correctly adjust but that is time well spent. That same adjustment is also giving you safe braking so take your time and do it several times if needed. I could copy and PM you the relevant pages if you wish? Mine was a pig to do the first time but now is easy. Nathan.

Have you checked the clutch components? Do you have the manual? If so then follow the instructions to adjust your clutch, usually just cleaning components and retensioning the spring but occasionally you will need to remove one or more of the shim washers on the shaft. Harrison state that disassembly and cleaning should be carried out at six month intervals. If you don't have the manual then buy one from Tony at Lathes etc. Nathan.

Thread: Waterproof cabinet / box?
13/04/2019 19:25:25

How about a plastic coal bunker? Cheaper than the Adept cabinets and larger. My 500kg bunker is approx. 600 x 1200 x 1000mm, keeps the fuel dry so should keep your RC dry. N

Fizzy, I think that Tony (Lathes) stocks them or you could do as I did for my small (150mm) 4 jaw and buy s/hand catch plates. Remove the pin, face it and then machine to suit. Works for me and has done for 6 years now. Nathan.

Thread: Windows 10 again

Thank you all for your efforts. Brian, I'll try those two surge protectors.,Danny, I think your suggestion is the only positive method if you know a storm is coming. SOD, I'm in the tropical bit of North Wales about 300 mtrs altitude and not more than a mile from the Zip World attraction. That unit from RS might not be too expensive when you consider the replacement costs for phones and PC. Hugh, thank you,I'll PM my details . Nathan

Thread: Tungsten Alloy
30/11/2018 21:25:46

Duncan, have you thought of Tungsten darts as your material source? Wrong shape but prices are low. With your skills you could find a workround? nathan.

Thread: Windows 10 again
30/11/2018 20:25:53

I should point out that by "satellite" I mean phones that are slaved to the base station. In no way I could afford or justify owning a satellite linked phone!! Nathan.

30/11/2018 20:21:28

Rik, they are plugged into a surge protected 4 way trailing socket. My feeling is that we're also getting it through the phone line. We've lost two phone base stations this year and are now running a mis- matched trio of phones. The satellite phones are always ok. Is that because they are not connected to the phone line or is it because they have less sensitive electronics? Nathan.

Thanks' everyone. I'm considering a Dell 780/790 SFF from Morgan Computers. it comes pre loaded with W 10 64 bit and 4GB of memory. I'll upgrade to 16GB and fit a larger HDD, if I can find affordable PCI low profile graphics and sound cards they will also be fitted. Drivers for my printers are available so that's not a problem and I may just upgrade from CS2 which was a freebie anyway. Nathan.

Is there a way of protecting routers and cordless phones from nearby lightning strikes, apart from unplugging everything?

29/11/2018 23:08:34

I should have said that I'm working from a cheapo Viglen tablet via wifi. I hate it as a primary machine!! nathan

29/11/2018 23:06:31

Today we suffered a close hit during a very short thunderstorm. The router,my pc motherboard and the ethernet cable between the two, plus the PCI ethernet card suffered damage.It looks like my HDD and 2 external drives are ok. OS is Win 10 32 bit. The cheapest option seems to be to buy a refurb PC. Should I stick with 32 bit or move to 64 bit? The only progs I need are CS2 and Paint shop X9, both of which are legal. All of my MS progs should be O/K. Any advise would be welcomed. Nathan.

Thread: Quick release hook
14/11/2018 22:00:48

Sounds to me as if Sam is describing a surface flotation system, not a fully submerged bag. In that case the bag is sized so that it is oversized for the lift and will not "explode out of the water with strops etc flailing in all directions" and if the bag manufacturer/supplier are involved should be perfectly safe. Neither manufacturer or supplier would wish to involved in a dangerous scheme as they would be liable if it went wrong. If correctly specified the bag should do no more than bounce on the surface . Nathan.

Edit because I quoted the gist not the actual wording.

Thread: Pumping water up a hill

A Ram pump is horribly inefficient, less than 10%



However, if you have a flow and no power source, they are very efficient at doing their job. They will work practically maintenance free and what needs to be maintained can be looked after by unskilled operators. They will also work 24/7/365. I have one on our local allotments site pumping over 380 mtr x 14 mtr head, it supplies a 10 m/3 tank. Over the three years it's been in use only the impulse valve has been replaced . Considering that it is made from common fittings and a booster pump pressure vessel and is only 3/4"/ 22mm bore it has lasted very well. Flow is not great but is constant and the secret seems to be to pump into a large bore pipe(we use 100mtr x 63mm mdpe) to start with, then reduce the bore diameter over the remaining length . Once full this system produces .8 ltr/min , or 1.152 m/3 day . It takes some time to fill the pipework but after that the flow is constant . I'll try to go down and take photos. If the OP thinks he has use for it, I have a Green and Carter Vulcan at 2.5" drive which he can have free. It needs a new or repaired impulse valve but is fine otherwise. Nathan.

Thread: wood turning

Re my previous post. It should have been "near enough" with a standard metal cutting insert. Nathan.

Thanks to all. I've found what I needed at "AZCarbide", they have a range of inserts designed for/suitable for woodturning. Nathan.

What did you buy and how much was the postage?

Vic, at those prices I was never going to buy! I just wanted the range of shapes and am now looking for the full geometry of each insert. There must be a "near enough"

Alan, that is also of interest, can you tell me if you modified from metal cutting angles to wood cutting angles?

All good info and many thanks. Nathan

Welcome back to the nuthouse Graham

I'll second that, I really enjoyed the original thread on here. Nathan.

Thread: wood turning

Phil, I've been a wood turner for many more years than I care to admit ! My Father taught me in the early sixties. Timbers used for this experiment would be English Walnut/ Sapele/ Honduras Mahogany/Burmese Teak and Cherry, all of which I have in store. I won't touch the Rosewood for the time being!! Nathan.
