Thread: Problems reading from a 3.5" floppy disc
20/09/2020 14:33:04

Try a disk cleaner in the drives.

Are the drive at the same temperature? Disks and drives expand and contract which can put the tracks out of alignment.

Thread: Burgess BK3 MK2 capacitor
17/09/2020 23:33:58

Do we know the required capacitor voltage? This is almost more important than the uf rating.

Thread: Tachometers sensor magnet
16/09/2020 00:10:24

Make sure that you stick the magnet the right way around, you just know that it will happen.

Thread: Use of 2 front wheeled motorcycles on the TdeF

Mind you Piaggio started it with their MP3 scooter.

It's always a shame when someone feels the need to resign (or semi) from a forum such as this but it has to be remembered that times and people do change.

I have been a moderator on an engineering forum for over 19 years now and it is noticeable how the users (members) interest changes over time. There is an initial keenness to be in contact with like minded people and to share experiences whether gaining or giving knowledge.

After a while the realisation sets in that you know as much as you need too and you no longer know more than those asking the questions. You also notice that the newcomers queries begin to get repetitively similar and suggesting that the search facility is used normally falls on deaf ears.

There are times, no doubt, when moderators may seem harsh but consider also the logistics of the forum. There is minimum advertising here because it is, I believe, run by a commercial enterprise. The owners therefore are entitled to set some rules and live by them. If these rules do not sit well with you then of course you have the right to stand back.

I do find it a shame that Barrie felt the need to publicize his disagreement with Jason as it does not allow Jason to defend his position and as such seems somewhat unfair. A quiet departure with PMs to close contacts would have been more diplomatic.

Thread: Hello

Looking at your lathe on lathes.co website it would be a shame to consign it to the scrap bin, hopefully someone can help you.

Thread: Any idea what this is guys & gals
24/08/2020 11:45:25

It looks to me somewhat similar to an air operated "mole" as used by the gas and water trades to drive a pipe through the ground.

Thread: Quality Finish
23/08/2020 14:39:59

Use a shear tool to obtain a smooth finish then fine abrasive.

Thread: How can I fix this LCD display?
20/08/2020 18:03:27

Check also the back contact surfaces of the LCD unit.

Thread: epoxy resin preventing from sticking.
14/08/2020 22:03:05

There are a few things available..

Non stick epoxy

Thread: Coping with voltage spikes
13/08/2020 18:49:14

At low engine/dynamo revolutions the regulator will be busy switching on and off to balance the battery/load.

Do the lights settle down as the revs come up?

Thread: TBH!
12/08/2020 13:13:25

Agreed, but it's all relative...

On a refrigeration forum I use one of the members from Iraq posted a picture of his car dashboard at 5 o'clock in the morning and a temperature of 50⁰C. ( Not for me I think)

Thread: Greenish amateur lathe enthusiast
11/08/2020 18:25:12

Found a copy of the manual here...

FF400 manual

Thread: Paint for mild steel sheet brazing hearth.
09/08/2020 19:37:18

Vehicle exhaust paint, some goes up to 650⁰C.

Thread: Viking Link Interconnector

Well that passed a little time reading up on that quite interesting subject.

It seems that there are less losses in transmitting DC power as it doesn't have a frequency compared with AC. These losses increase with the distance.

One factor which I believe could be important s that the DC link provides a system isolator between the two AC systems. This allows, for example, the North and South islands to be out of phase with each other but still pass power between each other.

Other things are that the DC cabling can be smaller than the AC especially on overhead cabling therefore towers can be smaller, cheaper, too.

Thread: DC motor reversing
17/07/2020 18:49:53

A couple of thoughts, I'm no expert on these things...

Are there any limit switches in the circuit?

Is the ram mechanically sound and able to operate in both directions?

What is the small PCB for?

Thread: Hallite washers

Are these bonded seals of any use?

Bonded seals

You mean a Dowty washer?

That's the name, for the life of me I couldn't remember it. It was only 40 years ago when I used them on a regular basis.

Many years ago I was in lane three at around 70 when the traffic slowed rather quickly.

I hit the brakes hard but also checked my mirrors, as trained, so as I came close to stopping I moved right towards the central area with my Dad, in the passenger seat shouting "what are you doing?"

Having stopped we watched the car behind me, nose down, head directly into the boot of the car in front of me.

Close call
