Thread: Solvent for degreasing engine, without damaging the paintwork?
14/09/2019 02:02:58

Naptha for all intents and purposes is white spirit. Whilst ethanol and isopropanol may not greatly affect the paintwork, they are not great solvents for oily residues either.Of the two, my money would be on iso-propanol. Paraffin as present in WD 40 might be an answer.

Odourless white spirit might also work, it has rather less solvency than the straight version.

Clive Foster,

Your reference to the tapers holding on a Velocette but not on a Gold Star is very interesting but would you be prepared to speculate on why the Gold Star fitting is less satisfactory? Is the Velo set-up longer? Just idle curiosity on my partsmiley

Are you by any chance the son of the great Bob Foster of New Imperial TT fame? If so, we have corresponded ages ago re my using some photos for my book on New Imperials

Brian,

No not correct. White spirit is wholly aliphatic but Mineral Turps is about 40% aromatic e.g. Xylene. For many products Mineral Turps is a much better solvent than White Spirit.

Shell used to market a solvent called X32 in Australia which is very close to white spirit. You might be able to buy true white spirit retail e.g from Bunnings.

Thread: RENAULT DAUPHINE
01/08/2019 03:20:15

Re postings on another thread:

Is my somewhat unreliable memory playing tricks on me? I always understood that the Renault Dauphine was something of a disaster of a motor car with a dangerously poor weight distribution at the front end. Certainly one place I worked at, one of our people was blocked off in the parking lot when he wanted to go out at lunchtime. The problem was solved by two not particularly hefty blokes picking up the front end of the Dauphine and moving it aside.

I also thought that the insurance companies had refused to insure Renault Dauphines after a while because they were a) unreasonably represented in accident figures due to the weight distribution b) prone to catastrophic rust problems that compromised safety.

Anyone remember this?

Many people in Australia outside of the cities use collected rainwater as their only source of water for drinking washing etc. Where I live, we do have mains supply but I collect rainwater for use on the veggie patch and in my home brewing. Not sure whether it affects the taste of the beer as I have never tried brewing from the horribly chlorinated and fluoridated stuff that comes through the mains.

Thread: CARBIDE BURRS

My thanks to everyone who replied, I should be able to sort something out from the sources suggestedsmiley

Can anyone tell me a source of carbide burrs? I need 6 or so burrs, cylindrical type, 2mms cutting diameter, to suit a Dremel, . There are millions (well thousands anyway) of ebay sites listing sets of cutters for dremel but these are of no use to me, I don't want to buy a sets of cutters with maybe 9 cutters in shapes I will never use.

I am not particularly conversant at computer searching so maybe someone can suggest a search term that would help?

Best wishes, Chas

Thread: Unsolicited email from SOLIDWORKS
06/07/2019 00:16:03

PAUL LOUSICK: Maybe I did not make myself clear - If I google solidworks I get plenty of available tutorials BUT no free tutorials for Solidworks 2018. Earlier versions yes but not 2018. Paid tutorials yes but none free.

However there could be suitable tutorials on individuals websites with titles like JOEBLOWSTIPS that I don't think would come up as sources of Solidworks tutorials if I search for solidworks tutorials on google. Am I correct in thinking this?

I was hoping someone could point me to a site like joeblows tips with the help I need.

As far as I know solidworks is the current industry standard for CAD work - would be interested to know if this is correct?

Regards, Chas

04/07/2019 23:06:05

I have access to solidworks and at 79 years of age I am starting to learn this program. (Is this a record? smiley). Not the easiest of the CAD programs to grapple with I'm sure, but there it is.

I'm having trouble finding a suitable tutorial and I suspect there is someone on facebook somewhere with tutorial(s) for Solidworks 2018.

Does anyone know of such a site or a good book on the subject? By googling I have not found any free tutorials for Solidworks 2018, only earlier versions. While there are probably not many changes to earlier versions it can be quite baffling for an absolute beginner if selecting a particular option does not produce the result in the videosad

Thread: Multi faceted drill bits - really necessary?
27/06/2019 07:58:14

Over time I have read many comments on the forum to do with drill sharpening, but have never seen it mentioned how the drill manufacturers manage to get a perfect result every time. Does anyone know this?

For my part I have a Picador grinding jig which I modified in accordance with Graham Meek's recommendations.It can't give split point or 4-facet sharpening but works very well for basic sharpening. At this stage I don't think I have an actual need for more sophisticated sharpening (as opposed to wanting) so I am quite happy with the situation.

Thread: stamford show vandals
21/05/2019 23:13:17

The Singapore status is one that I greatly admire, not only because as I get older and less able to defend myself physically I value my safety more, but because of the tremendous benefits that Singaporeans enjoy. When I first visited there in 1970 you left the aircraft by a ladder and the terminal consisted of about 6 shops and a few desks. Now there are separate terminals for arrivals and departures each with 100+ aircraft bays. Much of the Singaporean population has also been re-housed in that time also. Not bad for a place that is basically only a mudflat with no natural resources.

Crime of any kind is rare by Western standards. We tend to (over?)focus on the rights of the individual rather than what is good for society as a whole. Which ignores simple facts - that order can be maintained amongst the ferals by fear, and crime will run rampant if there are no real consequences. Any Singaporean will tell you that only visitors commit crime in Singapore - the locals know that due to strong policing they will be caught and that the punishment will be severe.

Who can forget the case of the American visitor who vandalised some cars a while back. He was jailed until his flogging was due and the prospect of physical punishment scandalised the American President of the day who wrote to the Singaporean Prime Minister.expressing his abhorrence of such a punishment. The Singapore Prime Ministers reply was succinct - Lets get this straight. America does not have physical punishment and rampant crime. We have physical punishment and no crime. And you are telling us how to handle crime?

Then of course there was the only attempted aircraft hi-jacking in Singapore. There were no negotiations and 7 attempted hijackers were shot dead. No-one ever attempted to hi-jack a plane in Singapore again.

My view is that there are some people who can only be reached through their personal suffering e.g. flogging or punitive jail sentences.

While this will offend people like Neil with their highly moralistic approach, I can only say that we don't have an idealistic society where everyone listens to reason and acts for the common good. We are never likely to have one, and the efforts of the do-gooders have only led to the present high crime levels and deterioration in the lives of the bulk of the law-abiding citizen.

What a wonderful word freedom is. It can lead to the most awful deterioration in the populaces well-being yet it is eagerly sought. Can anyone name an African nation that is now "free" from colonial rule where the populace as a whole are better off than they were under colonialism?

I like the sound of Bricky's idea and although it is subject to the possible errors already listed above, it sounds a whole lot more convenient than turning up a plug gauge each time. Can anyone (Bricky ?) provide a sketch of such a device?

Thread: 1959 Nsu quickly
30/04/2019 22:42:10

I for one certainly remember the NSU Quickly, the things were ubiquitous, you saw them everywhere. They were , well-made and extremely reliable, but at that time you would have needed considerable foresight to see that nearly 60 years later they would become collectors items.

Thanks to the OP for saving this piece of history for us all to enjoy

Thread: Threading 1/8 stainless steel
30/04/2019 22:30:19

Which raises the question of die material. I have heard it said on the forum that carbon steel dies can be sharper than HSS dies and may be a better choice for some materials e.g. brass or stainless steel. That may be the case but would a CS die wear more rapidly than HSS? In my case this is important because I do repetitive tapping of 5mm * 0.8 mm in 303 stainless when making my motorcycle levers.

Trying to thread stainless of any variety with a die that is not quite sharp is only going to lead to tears on this may be a factor in the OP's posting

Thread: ER25 v 5C Collets
18/02/2019 06:14:18

Thanks Jason. You have been a major help.

Chas

17/02/2019 20:43:28

Thanks to all who replied.

Jason, on reading your post I think I have been guilty of blinkered thinking.

I had dismissed the idea of using a 5C chuck because it seemed so much more trouble to install each time I wanted to use it. However I now think that if I set up such a chuck on a dedicated back plate I will be able to screw the whole assembly of clutch+backplate off the lathe spindle thread and screw it back on again next time I want to use it, without losing concentricity.

There has to be some loss of accuracy doing this but I think this might well be within acceptable limits for what I am doing (reproduction vintage motorcycle parts e.g control levers). Does this sound reasonable to you?

The idea of using ER collets for square stock is likely to come in useful someday and I have tucked it away in my memory banks for future use, However it is a ponderous way of doing repetition work compared to a collet chuck.

Chas

16/02/2019 22:51:11

I'm not sure if I should apologise for re-opening an old post as many forum users seem to apologise for doing just this, but it seems better to me to keep related topics together - it makes searching for help so much simpler.

Anyhow.....some time ago I bought a threaded pull-through device from a local supplier for 5C collets (nothing to do with arceuro I'm happy to point out) to use in my lathe.This turned out to be an abortion of a thing, Slow to use when moving stock forward for the next item and prone to unscrewing in the wrong places.

I then read a forum post where it was suggested that a Stevenson's Collet block could be set up in a 4-jaw chuck and used as a collet chuck that was opened and closed from the front end of the lathe. This idea worked absolutely brilliantly for me. Fast and convenient.

Problem solved - except how can I hold square-section bar?

In another thread by the late,great, Earl of Bridgeport and Sumpwater he commented that Jason B had proved that an ER collet could be used to hold square and hexagonal stock, but I am unable to find that reference.

Alternatively is there a way of holding my existing 5C collets from the front of the chuck i.e. by compressing the front of the collet into a taper, in the same way that ER32 collets are closed?

Regards to all, Chas

Thread: Get on yer bike
28/01/2019 21:56:27

My experiences more-or-less co-incide with Peter Shaw's. However our local gymnasium has exercise bikes with a screen in front of them and you can choose about 6-7 rides around Paris and the same in Rome - so as you pedal you go on a bike ride. I think they must have filmed the video in the very early hours of the morning because there are no lunatic car drivers around. I would not like to try those rides in real lifesmiley

Thread: SENSITIVE DRILLING
18/01/2019 21:23:09

My grateful thanks to everyone who repliedsmiley

The answer turns out to be exactly as given by SOD and I can now see how it is meant to work.

I just don't know how Jason B finds the time to help so many people on this forum, but it is much appreciated by me. I did buy the correct small chuck at the same time as the sensitive drill.because none of my existing chucks will hold such small drills. This was lucky because I had not realised just how tiny the correct chuck issurprise

I shall be using the device in my Bridgeport Clone milling machine which is where I do all my accurate drilling these days

Best wishes, Chas

Under normal circumstances, yes, but I believe ketan is in china at the moment. I don't know if they have other staff that could help.
