Thread: Built-up edge
13/10/2019 22:15:56

You have not said what type of Alu you have. I would expect HE15 or HE30 to machine quite well at the speed you quote.

Having one time ordered Alu as HE30 I got some Alu which turned like chewing gum, changed my supplier PDQ.

Thread: What solenoid to use?

There are some gravity type flaps set at a slight angle that only open when there is internal pressure. Often fitted to cooker hoods, no leccie iused at all.

Thread: uv cured gap filling adhesive
08/10/2019 13:55:34

For some time UV cured optical cement has been in use in the optical manufacture and spectacle lenses, particulary the type with a close up lems attached.

Prior to the UV cured optical cement Canada balsam was used that slowly yellowed with age. From what I see in the trade the UV cured cement does not yellow.

A recent Win 7 update has added an address bar to my bottom bar on the screen, what is this?


Thread: Water in fuel
29/09/2019 08:59:17

It comes to mind, when I bought my first new Ford Escort Estate the fuel tank was leaking, I went to the Ford garage under warranty and they agreed and ordered a new tank but after a 2 week wait decided to take things into hand myself. Drained the tank and flushed out with water a few times and could not smell petrol anymore. I was able to take it to a friend who had a gas torch and fluxed the the cleaned area and flooded it with solder and killed spirits.

On examination I could see tha the petrol tank interior was lead coated ! so no corrosion.

PS, never did get the replacement petrol tank. Thank you Ford.

PS. sorry, I forgot to mention that this was an Export car, which may have a relavance.

Thread: Worried
28/09/2019 10:02:48

It has got to the point now that I no longer worry about the mpg, I just fill up with £20.00 a week and that does it. Even though the car has diagnostic fuel usage I dont bother looking,

here is a point, I have a class 6 engine in my VW. If I use Shell diesel within a few miles the catalyst light comes on and the book tells me I have to do at least 20 miles at 40mph to burn off the rubbish? If I use run of the mill Sainsbury Diesel, no problems. There is a price difference but it is lost by doing the 20 miles to clean the Catalyser unit.


Thread: Water in fuel
24/09/2019 14:12:20

One time I filled at a newly opened gas station, I use diesel, shortly I had engine problems and found that there was water in my fuel filter. I ended up buying a new fuel filter untit complete due to corrosin of the body inside.

Complaint to the gas stations just drew blank stares. Ever after that I had to have one of those fuel line filters which collected all sorts of muck.

Obviously not of much use to teh poster but as a source of water maybe.

Thread: What the he**
24/09/2019 07:55:08

I had a Ford escort front spring break where iit sits in the pan in the McPherson strut, they are colour coded so went to scrappy and found one of the right colour code and easily fitted it.

Oten when walking the dog I see bits of spring laying in the road and always on a roundabout, I pick up and dispose.

Thread: Surface plates
20/09/2019 10:35:38

You would be surprised at how useful a surface olate is from scribing rising dimensions to checking flatness of parts being made.

I had a bronze casting and as I worked it it distorted and I only found it by using the plate and a V block.

If you have a Scribing/measuring device it is somewhere to store it ready for use.

Thread: Fiducial lines on a Zeiss Microscope Eyepiece
20/09/2019 10:31:27

There are many factors in Microscopy that are made for different usage, I have seen some where incident light use and reflected light so maybe a different focus there. My own use has been with reflected light looking at PCB's and the resolution is critical for dry joints in multi layer boards.

Sadly I no longer have contact with Leica since I left in 1999. I would think my contempries were no deceased.

It might I wonder if it to focus on meniscus plates where the focus changes through the meniscus?

Fiducial lines are usually on the focal plane and appear on the negative or print for measuerment purposes, I wonder if the lines in the eyepice appear when used with a camera?

Thread: Petrol Gen for 7 1/4 locomotive
16/09/2019 21:55:35

One post mentions Hydraulic drive motors. A petrol engine driving a pump to drive the wheels, foolproof. No electricity, no danger wow.

15/09/2019 08:35:45

I have always found that what a gen. is rated at is not what you get. I then triple the Gen. rating to get what I want and this of course means a jump in size. It all sounds feasable for your project and I would at first set it all out and prove it before comitting to hardware on the track. Generating leccie is about 4 x the cost of household leccie.

Thread: Myford 254 thread dial indicator
09/09/2019 21:48:02

Hi Phil, the brochures are 1999 vintage so not current and as you say the lathe is out of production.

I had just purchased an ML10 so wanted the brochures to get bits I wanted.


09/09/2019 12:19:39

I have the sales brochure and available parts for the 254. the part. no. 95/136 for metric threads, in the listings priced at £100.81.

Note. it is only for use with metric threads. it goes on to say that if used with the imperial conversion set. 95/078 on a 254 lathe the leadscrew nut must remain engaged.the part no. for the imperial thread ind. iis 95/105 and cost £36.89.

Hope this is some help Clive

Plus £61 for the detailed build instructions.

Thread: Why does the micrometer have a second knurled segment
05/09/2019 14:28:20

Chris. the small ratchet thumbwheel is to give a uniform pressure when measuring close tolerances, Thumb pressure on the large thimble can vary so much as to give odd readings.

Thread: Torx head variant or faulty batch?
21/08/2019 15:18:57

Then of course TORX put a dimple in the bottom of the recess! so I had to buy 20 sets of new TORX drivers to go with the old ones. My answer was to put a screwdriver against and wipe it out.

Thread: Wasp trap - suggestions please
20/08/2019 09:08:27

Re-the wasps, wasps as such do not eat and can only suck liquid even though they have mandibles. They forage for protien for the larvea who as a reward will give a drop of sweet lliquid from a gland on their rears end. This prompts the wasp to forage again.

The nest, can be in a tree or loft or shed or underground in a vacant mouse hole. They will enlarge it considerably.

Often you will see lumps of mud on your car from excavations.

Disposing of a nest, do it after dark using a torch as a shield. Allowing you to get close. Foam cans with a tube are good but slow. If done in the daytime foraging wasps come back to find the nest smell gone and they hang about for days.They are Pheromone driven. Given from the Queen. Do not use petrol and ignite as I have seen a chap lose his hair and have facial burns as the petrol blew out of the hole in the ground. Heavy volatiles like Nitro Cellulose thinners kill them but put a dustbin lid over the hole to keep the vapour in. They will not re-use an old nest but will build anew each year. Only a hibernatining fertile Queen will survive the winter.

It is an Amyblyteles Armatorious, very common and parasite of Moths. No common name.
