Thread: Virtualbox advice
01/04/2020 16:21:30

I have used a number of VMs to test new OSs or use Win7 under Linux.

Each time I have used the default network adapter settings. The network appears as a wired connection on the VM, the default adapter settings have been used (I haven't changed anything), and it is set for NAT (network address translation).

Things may work better after installing Linux on the VM, then installing the VBox guest additions to ensure all proprietory drivers and software are installed.


Thread: New design of mains plug?
30/03/2020 18:05:45

The earth pin on that plug is shrouded which is another no-no and instant giveaway of a non-conforming plug.

Anthony is the lucky first responder so the board has a new owner. Good luck to all the brave people who are taking this project on, please let us know how you are getting on.


PCB arrived safely yesterday, now to source the components - most are somewhere in the parts bin!

Thanks for the kind offer of the PCB, Doug. Much appreciated.

Hi Doug,

I am interested in the PCB. PM sent.

It may be an apocryphal story but was informed that the low hrs E.E Lightning in RAF Hendon museum in '70s had been retired due to mercury spillage in cockpit.

The aircraft in question was XM170, which was contaminated during build. Very low flying time on the airframe when it was scrapped..


Thread: Ebay - BIN watchers
08/04/2019 17:37:15

I add BIN items in my watch list, so that if the price is reduced I seem to get an email notification quicker than one of the opportunist 'You viewed this item at X price, it is now reduced by Y".

Hi Jeff

The year for the Vauxhall is 2000 the engine fitted as standard is a BMW 6 cylinder 2.5DT, I belive the same engine was also used in the Range Rover, P38



The engine code for the BMW engine fitted to a MY2000 Omega is X25DT.

Unlikely to be major differences to the mechanical parts of the engine, just to the engine management system and other emission control equipment. The first letter of Vauxhall/Opel engine codes defines the emissions standard the engine meets.

I signed up to be on the waiting list for the lightning detector hardware that feeds into the Blitzortung/ website.

Signed up in July 2014, where there were approx 1500 people on the list. Now I am at no.35, the list has grown to 4500. It grew quickly after the site was featured on national news channels...

Thread: Boll Aero

Does it draw fuel to the carburettor if turned over with a finger covering the air intake?

Do you get any signs of life if you prime it (sparingly!) directly into the exhaust port?

From the number of completed examples that were shown on Ron Chernich's website ( I don't think there were any show-stoppers in the plans. What date/revision plans do you have?

Nice work - looks like you are making good progress! smiley

I have used mild steel and brass for the split taper bush in the past on various engines, with no issues.


Aluminium, I think, may cause issues, by galling and welding itself to the prop drive hub or the crankshaft itself.

Thread: In-line Diesel Engine Model
17/01/2018 10:30:52

A construction article for 'DUX' - a 9.5cc single cylinder Diesel with solid fuel injection, designed by Martin Alewijn - appeared in Strictly IC magazine from Dec 2000/Jan 2001 to Aug/Sep 2001 (issues 78 to 82). I understand that back issues of the magazine are still available from the publisher at

As I recall from the article, the issue of drilling a very small hole in injector was avoided by making a very fine scratch in the conical seat of the injector needle, which then provided a path for the fuel and the necessary atomisation.

Thread: Fitting Ikea Kitchen Units - Me workshop wall is on the way.
01/11/2016 21:05:29

Have you seen this installation guide?


I have just installed a new Ikea kitchen, and found that it is easier to mount the cabinets directly to the wall and avoid using the rail. This is especially so where two walls are not at 90 degrees to each other and there needs to be some 'fettling' of the cabinet positions to get everything to fit.

The plinths do clip to the cabinet legs, and the Metod legs are adjustable for levelling. Product code for the legs is 402.055.99. They are pre-adjusted to the 80mm height of the plinth.


Thread: 10-32 UNF Threaded Rod
06/07/2015 20:59:30

I think the holes in the plate are towards the tighter end of the thread specifications, as an M5 screw only goes in about a turn and a bit before binding up.

Given the price of the Sherline accessories, I would expect this, though!

06/07/2015 15:43:21

Thanks everyone for their inputs so far.

I have located a more reasonably priced source for UNF studding - £2.88 per ft. A reasonable price but still a lot more than the metric equivalent.

As there is 3/16" MS bar in the materials bin, and a suitable die is on its way, I think I will give making up some studs a try. Will also make a few 10-32 test holes and see what happens when an M5 tap is run through. Come to think of it, I am sure I have an M5 helicoil kit, so maybe I will go for broke and just re-make the holes in the sub-plate with that (if I have enough of them!)

Do you really need to use 10-32 UNF?

M5 is so very close in diameter and you can buy S/S studding at £1.53 per metre!!

The clamping plate on the mill table and all of the accessories are tapped for 10-32, so I think it would cost more to buy a new piece of ali plate and re-tap it and all the other parts than get hold of some more threaded rod.

A valid point though, and one to keep in mind if the UNF studding isn't easily available.

Any links or auction numbers? I looked on there and couldn't find any.

05/07/2015 16:36:16

Afternoon all.

I am looking to obtain some 10-32 UNF threaded rod, to chop into 1-4" lengths and make more hold-down studs for my Sherline mill.

It can be ordered from the USA where it is more commonplace, but the carriage works out more than the material.

Does anyone know of a UK based supplier? I only found some at Cromwell's who have a 'special offer' of £14 for a metre.

It only needs to be self-coloured steel, not diamond-coated unobtainium!
