Thread: Getting old, selling lathe

Sounds like between us we need to form a society of Amputee model engineers! However fingers don't count or we would be flooded with vacancies.

Best wishes, it sounds like you have a good mindset. Adapt and overcome.

Take the utmost care! We need all the members we can get!

I hate to repeat what has been said elsewhere, but you really need someone on hand to assist with these things. It's like trying to learn to drive by post otherwise.

Everyone here is very happy to assist in any way they can but its quite difficult to do so via a forum. If you can speak to your local model engineering society; ours certainly has lots of keen members eager to share their experience.

Really nice work, it's given me an opportunity to go back a while and catch up with what you've done to date. Following with interest.

My previous post I think got lost. I was pointing out that wartime equipment was often unpainted or blackened to save paint for the war effort.

Great news, I look forward to seeing them.

Thread: Oil drippers
07/06/2022 20:07:52

The easiest way to describe it is to gently take one apart and you will see how it all works. If you have the ones I think you have, with the toggle on the top open (vertical) a sprung loaded pin will be retracted from a hole above the little sight glass, allowing the oil to drip. If this isn't happening you undo the locking knurled wheel under it and turn the cap to gently move the toggle upwards until the hole is open. If you do it the right amount it will shut when the toggle is flicked over. I was once told by an older machinist that the "right amount" of flow is when you are just about getting bored and wondering if it will ever drip... and then it does. obviously that is very subjective!

It could be that the lubricator is blocked, or the mesh at the bottom is gunged up. Again, you will only know if you carefully take it apart, laying it all out in order. It will soon make sense. Just be careful not to damage the glass.

Swarf is the only thing I can make with any accuracy. Welcome

That connector does seem a bit of a silly design.

Bank transfer doesn't give customers any comeback in the event of issues; I would politely suggest you find a method for people to pay via card, paypal etc as although your current circumastances are entirely understandable, it does mean that the state of flux means people may be less confident paying for expensive items in a way which means their money could disappear if any further issues crop up.

You have some nice items, I look forward to seeing the site evolve.

I find his videos unbiased and fair. But I feel I can comment, I've watched a lot of them. Oddly enough I don't comment on things I've not given a fair crack of...

Thank you Michael.

Thread: What does this circuit do ?

The value looks reasonable given the size, which again gives weight to the reservoir capacitor idea.

Thread: 2" Fowler plough
27/05/2022 07:07:11

I think we need a bit more info or even better some photos; It's going to sound like pedantry but it really will help us narrow down what you need!

Are you referring to the double sided ploughs pulled by ploughing engines? I assume you are not talking about the ploughing engines themselves?

Thread: What are the best quality needle files?
27/05/2022 06:25:10

I've still yet to find a file that gives as nice a finish as the one on my old leatherman! I think it is an industrial diamond coating of some kind. It doesn't seem to dull, gives a mirror finish and can be unclogged easily.

I'll give those Arc files a try too; I'm sick of poor quality needle files from allegedly good names. Of course, in my case this could be the workman blaming his tools....

I have no help to offer, but I'm intrigued as to what it might be!

.... Turned out they were showing a clip about Thrust SSC (Which I helped build and run) and I was in the background.

I have a funny feeling I remember that coming to Boscombe Down for testing? Or did I make that up?

Nice to meet you Mike.

Thread: HOW FAST - ANEMOMETER CALIBRATION ?
25/05/2022 07:01:07

The ETPS used to use equipment like this mounted to the top of a 4x4 (a Jeep is the first one I remember, a Nissan Navara later) on tall cross-braced poles mounted on a roof rack. This anemometer combined with a large fluorescent pole allowed them to do rotary wing cross-wind trial flying up and down the runway in close formation with the vehicle giving them a good visual point of reference, and a telemetry uplink of wind speed and direction (cross referred to the vehicle GPS speed) to the recording systems to allow them to collate the data together. However the point of interest here is that the poles were mounted high enough above the vehicle to try to counteract the affect of the airflow displaced by the vehicle. I seem to remember to total height from the floor was more than ten feet, but don't recall exactly. Anyway, this was considered enough separation to be good enough for their needs. So you need a roof-rack and some cross braced poles! And I would use GPS rather than the speedo. If you use a long straight on a calm day you could go in both directions and take an averaged reading over multiple runs.
