Thread: Lockdown Reading - Nevil Shute Rediscovered
05/07/2020 20:20:44

I have read all of his books including a couple that were only published after his death. He had an amazing way of describing ordinary events in a way that can really involve you.

My favourite is still "An old captivity"

Thanks for bringing this up, it may be time to dust off a couple of his books.

Thread: Pesky Government Announcement!

So who would pay for advertising on Classic FM?

I do listen in the car and at home and am staggered by the incompetence of who ever sorts out the adverts.

You can often hear 10 seconds of an advert followed by a few seconds of another and then back to the original. Sometimes with comedy results.

I wouldn't have thought this possible in this day and age but Classic FM seem to be able to do it again and again.

I have felt the frustration of Peter Shaw long before the Govt announcements started.

I got sick of hearing the joyful singing of "The Claims Guys" and then was horrified after the deadline to find that you can claim if your bank mis sold you investments. They also ran adverts by several charities for free will writing which coupled with the cancer care adverts caused my wife and I to dub it Classic Death M.

I have nothing against any of these and am not against adverts and announcements but there are many things that need to be advertised and much that should be announced Just not the same things every half hour.

Now listening to Prime Music smile p

Thread: Hermes Parcels
12/06/2020 10:30:28

The world has truly gone mad.

Hermes (through eBay's packlink) put their price up to £4.36 for a 2kg parcel the other day.

Now UPS have lowered the cost of their next day service to £3.75 for 5-10 Kg

Obviously I am not complaining.

Its all blamed on virus 19 but they are still charging the same for a poor service ,

If only!

I use (or at least used to use) Hermes through eBay. They just put the price up for a 2kg parcel from £2.85 to £4.36

As an ebay trader I have seen an increase in trade but also an increase in costs. If a parcel goes missing it is the suppliers responsibility to replace it and I have had to do this several times. On cheaper items it is not worth the bother of trying to claim.

I sent a parcel out on the 28 April by Hermes that arrived Yesterday.

To be fair they are better than they were but I'm not that keen on them as a company.

Both Royal Mail and UPS are struggling at the moment so I wouldn't be too quick to judge any of them.

Thread: Newbie trying to thread
04/06/2020 22:53:39

Ahh,

Sorry about the left hand thread bit. The lathe I use for manual threading has a dog clutch arrangement, when I reverse it I am operating the tumbler reverse and not the motor direction.

Good job on the thread though.

Regards.

David.

I should have said that apart from not withdrawing the tool,the method is correct.

Take small cuts rather than trying to do it in one or two passes.

David.

02/06/2020 10:12:56

Hi,

If you reverse the direction you cut a left hand thread!

So no, most definitely not.

Don't be too upset with yourself though, it isn't that intuitive!

Regards.

Thread: Machine Tool Peripheral Hoists

Posted by Alan Waddington 2 on 28/05/2020 21:58:35:

Felt stupidly dangerous and reckon it won’t be long before i simply can’t do it.

I'm getting to this stage too. I like the concept but am not keen on the toolpost mounting, not because I don't think it isn't strong enough but because it seems a pain especially as it has to be changed over depending on which machine you are working on.

My DSG and mill are next to each other so I think some sort of swinging arm between the two is the way I will go.

Regards.

David.

I saw this too and didn't like the idea of 500lbs hanging off my toolpost but having thought about it, I'm sure it is okay.

If you want something to compare, have a look at how the ram is held on a cheap 1000kg engine crane. The materials on these are cream cheese painted to look like cast iron. He has this mounted to a quality toolpost on a 17" Monarch lathe. I would say that most lathes could lift the weight of the chucks that would be used with them from the toolpost without too much bother.

Sadly though his channel has just turned into a series of paid endorsements ( at least that is how it seems to me ) and it is difficult to gauge how useful any of these things are!

Regards,

David.

Thread: Oil
17/05/2020 09:23:51

I generally use the appropriate oil for the job ( easy for me because I sell oils ) but agree that any oil on slideways will probably work. Yes the proper slideway oil will reduce stiction but I doubt you would be able to measure the difference on an ML7 tailstock.

Viscosity is more important, especially with bronze bearings fed by drip feed. My Jones and Shipman 540 uses a mix of oil and kerosene which is like water, chucking engine oil into this is not a good idea!

If running machines with bronze bearings be careful with the oil that you use and make sure that they don't run too hot.

I realise that this is obvious to most on here but point this out for the beginners who may stumble upon this thread.

So yes oil is oil but not always.

Regards.

Thread: Things bought from ebay

Posted by JasonB on 03/05/2020 07:07:25:

Stevie, although Chinese they are good quality Chinese as I said previously. Also did you use the Zoro/Chromwell list price as most commercial and in the know private buyers will be buying at 50-60% less than list but still a good buy.

Hmmm. The Zoro / Cromwell pricing is a sore point.

Last I looked Cromwell are nearly double what Zoro charge in some cases, despite being under the same ownership.

First class large letter posted on the 14th arrived on the 24th just to give some idea of how bad it can be. some second class has arrived in two days, so not all bad.

Thread: Any Idea What Lathe This Is?
26/04/2020 11:21:59

Personally I would have a go at it. Try not to spend any money on it or if you do spend it on things that can be kept if you get rid. This can include chucks, toolposts and the other bits needed to use any lathe. There are many videos on youtube that would guide you in everything from adjusting and painting to completely rescraping it.

At the end you will either have a serviceable lathe or a good education.

The fact that you haven't gone out and bought gleaming example from a showroom says that either need or budget will not allow you to spend a huge amount on a lathe (nothing wrong with that). My point being that there are many lathes out there that look much nicer than yours but are just as bad and learning how to spot them is the difference between having something that is a joy to use and constantly being frustrated by it.

Good luck whatever route you go down.

Regards.

Thread: Fake Mitutoyo indicator on Ebay
23/04/2020 12:31:23
Posted by Clive Brown 1 on 23/04/2020 11:48:29:

It's a fairly convincing ad. except it doesn't actually quote the name Mitutoyo in the text. Surprises me that it didn't sell for more, considering the price for the genuine article.

BTW, Quoting a London location for Far-eastern items is not uncommon, but I think it's breaking Ebay rules.

I trade on ebay and was notified by them, earlier this year, that they were going to start penalising traders that did this. The reason being that people were complaining. That said I still notice huge numbers of people doing just that so nothing much has changed. You can generally tell by the delivery time.

Regards.

David.

Looks like a cheap copy of my Mitutogo.

What did you expect when the real thing costs £7.50?

Still when you drop it, I doubt the tears will flow.
