Thread: Boxford Model A leadscrew gearbox.
12/06/2020 16:58:38

Hi Oldiron,

That was an interesting video which gave me some ideas, but unfortunately dear old Tubalcain didn't actually strip the box down it was mainly concerned with cleaning it up. But thanks for the link it was useful,

Hi, I've not posted for some time, I've been out of circulation. I have a Boxford imperial gearbox, leadscrew and clamp nuts which have become damaged by fire and rust. It has been dry stored now for several years but I would like to refurbish it and pass it on to someone who has a model B or C Boxford and would appreciate a chance to upgrade their lathe.

However, I have not dismantled one of these before and would be grateful for advice fro anyone who may have so that I don't make any serious mistakes.

So does anyone know of any pitfalls?

Regards

Hi Peter,

Thanks for that, I can't get there with Firefox but I tried the link in Microsoft edge and I can confirm that it is still downloadable and anyone with a small lathe, Myford, Boxford, Harrison etc should have a copy if they are to do any screwcutting.

That video rought back some vivid memories I thought were lost. I lived in the Black Country as a child in the late 40s/early 50s and we were surrounded by steelworks and foundries large and small as well as drop forges. I remember my Dad and Uncle wearliy trudging home from the foundry after a 10 hour shift where they worked usually wearing old army greatcoats from their time in service in the 2nd WW, Dad washing in a white enamel bowl with a blue rim (no Bathroom).

There was no PPE worth mentioning in those days - I note that some of the guys in the video had what looked like hessian sacking tied around their legs for some sort of protection. I remember also the guys who were injured doing that work, including my Dad, some seriously, some not so bad. but there was little or no social security so work had to go on. I remember how bad it was when my Dad couldn't work for several weeks. My Uncle was a moulder making sand moulds so his only problem was the silicosis he eventually died from..

And I hear that those were the good old days. Perhaps they were for some.

Thread: Boxford change gears for screwcutting.
24/04/2020 15:23:34

Hi Dave and Ronald,

those are useful resources wghich I have addad to favourites, however I particularly want a copy of NthreadP because it had the facility to input the gears owned and the leadscrew pitch/tpi and made hth calculations based on one's won situation. I note that Howard's list ins particularly for the Myford lathe and needs more calculation if one has a different lathe and leadscrew - mine is a metric Boxford. NthreadP allows one to enter and save all pertinant information and add further information such as newly aquired gear wheels. It really is a brilliant little program, I hoe that it's not lost.

Thanks for your help,

TerryD

Thread: Boxford change gears for screwcutting.
24/04/2020 12:15:53

Hi all,

It's several years since i posted here but I'm now active again after retirement and isolating due to CV19.

Some years ago I downloaded a small program, suppose it would now be called and 'app', which calculated gear trains for changewheels on lathes. You input leadscrew pitch and your list of changewheels and it would calculate sevearal alternative possible trains.

It's most useful feature is that it could calculate very close approximations to cut imperial threads on a metric lathe without a leadscew gearbox and visa versa, without using expensive conversion gears. I accessed it from Tony's Lathes.co.uk website and the link is still there but the original download site is no longer. I have searched and the 'app' appears to have disappeared altogether.

It was called NthreadP, and was a free download. My copy was lost in a hard drive failure some time ago and I'm hoping to find someone perhaps who has a copy of this very useful program. I would like to make it available again via my blog so I would be extremely grateful if somone could send a copy, perhaps via Dropbox or similar.

Best regards and keep safe,

TerryD

Hi all,

This is my first post for several years, it's nice to be back.

There is a building site in a French forest where a 12th century castle is bering built from scratch using techniques, methods and tools of the era. Most materials are processed and made from what is available locally.

There are several episodes on the extraction of iron using a primitive blast furnace which may be of interest. They are from the first series, episodes 6,7,and 8. The program is in French but with English subtitles. You may find it of interest.

I hope that you enjoy them - keep safe,

Thread: Retro Modelling help needed (and lathe)
02/08/2017 09:18:53

Hi Stewart,

If you want retro there is an Australian guy who produces videos on YouTube (I know - more technology but it's not all bad) At the moment he is producing a series on his building a version of the Antikythera machine (ancient Greek mechanical computer) and is doing it using tools and methods that he believes may have been used by those ancients.

He has even made his own files from case hardened mild steel and uses these to cut the gear wheels. His videos include ones which explain how he believes those Greeks adapted their methods and tools in making the machine. Well worth watching.

He goes by the name 'Clickspring'. Just search on Youtube for him and 'Antikythera machine. These videos are also very well produced and are as polished as his excellent craftsmanship which I can only dream of achieving. His videos on making a skeleton clock are also excellent.

His video on making hand files is here:

Thread: Old Boxford Lathe
15/08/2016 12:17:50

Hi Charlie,

Looks like a CSB. These were basic lathes made for the education market, mostly secondary schools. I have one of these as well as a later BUD (UD - Under Drive). I must admit that I prefer the Bench mounting of the CSB (and other B and A models intended for bench mounting).

These are sound, capable lathes and if from a school may have dints on the bed etc but will probably have little wear as they had only limited use generally and with care the dints can be stoned out. Collets and draw bar generally sell for a good price especially if you have the collet adapter for the spindle and spindle nose protector which screws onto the the spindle nose thread. I use a different collet system i.e. the ER 32 system. Do You have a compound slide and toolholder?

If there is no play in the head bearings, I suggest you leave well alone they have taper roller bearings back and front. There are instructions on how to set the bearing pre load in the parts lists for these lathes, available for members in the files section on the BoxfordLathe_UserGroup on Yahoo. The excellent 'Know Your Lathe' Book is also available there.

I would personally not use the rear drive belt as a clutch - and I still have all of my fingers. As a lathe user for over 50 years I have seen all sorts of mods which have been made to these machines - most of them dangerous, if the manufacturers had thought it a good idea they would have done it believe me.

Do You have any gears to drive the leadscrew? If not I may have some duplicates I could let you have at a good price, message me and I'll have a look see. Otherwise they are again usually available on eBay. Don't buy a whole set, just the ones you need as you get a bit more experience.

As for help using it MIT (Massachusetts Institute of Technology) have some excellent tutorials on the website search for 'MIT TechTV Videos'. Just found the first lathe video - here-

http://techtv.mit.edu/genres/24-how-to/videos/144-machine-shop-8

There are others on the lathe in the series. BTW there is a list of Boxford serial numbers and dates on Lathes.co.uk.

Enjoy your lathe,

Terry

I can't comment as it will cause trouble.

However, if someone posts about the bad weather and not being able to go somewhere which relies on public participation by visitors, we could get sued when the public don't support the particular place being visited because we posted about the snow.

What I have done is the correct course of action.

What a load of Tosh (politely put notice), who gave you the legal advice on that one, I suggest you get a new solicitor.

Next thing is that the Met Office, BBC et. al who are reporting the bad weather around London and the police, the RAC and the AA who are recommending not to travel will all get sued. Whatever next - goodbye, see you all on MEM, nobody seems to be worried about weather reports there.

Why not go to a forum where you can speak freely on the subject

We don't want MHS being sued for making it snow as I could not see anything wrong with the thread and I was the last to post.

I intend to, it appeares that David is making up new rules as he didn't want to hear "bad comments" (? - who decides 'bad' about the show.

Moderation on every other forum or comment column I have ever used is applied to individual posts which break the rules of the forum, usually they are: Spam, Pornographic, extremely abusive or libellous, not for curtailing free discussion. I have never seen more than one or two posts moderated, never in all of many years of using the internet, a whole thread.

Whatever happened to the of quoted maxim:

"I do not agree with what you say but I will defend your right to say it"

I thought the internet was all about freedom of speech. Says a lot about this forum, I think I'll stick to MadModder etc in future. At least posts only get moderated according to the rules and not the whims of the moderator.

Thread: Where do I find a roller Filing rest for a lathe?
18/01/2013 07:25:36
Posted by MadMike on 17/01/2013 20:57:40:

I have read this thread with some interest, caused in no small way by total curiosity.

What are you guys using these filing rests for? Don't you simply turn metal in your lathes to produce something of a known accurate size and finish. For extremely accurate high finish work do you not simply leave a grinding allowance and grind to final size?

Sorry if I appear stupid, I often do apparently, but I just do not understand this one. Help please.

The filing rest is not to be used when the lathe is running smile o. It is used when the work is stationary and as pointed by Roderick is used to file flats, squares, hexagons etc on the end of shafts or other parts after turning. An example may be spanner flats or hexagon on a part. It is especially useful when a milling machine is not available and is often more convenient for 'one offs' than the mill.

A good friend of mine who was an excellent modeller used one when reducing the heads of BA bolts for a better scale effect when building his V8 miniature engine.

Terry

Thread: Milling Machines

Posted by steve clark 2 on 17/01/2013 18:04:56:

Well here's a question for you, these are hobby type machines right, who makes steam engine related parts for their train sets for example, I assumed that the tolerances for such parts are important so it would kind of follow that the machines would be a precision instrument??

Hi Steve,

I promise that this will be my last post on this subject. Precision as you call it does not lie in the quality of the machine necessarily. It lies in the hands of the user, and these skills comes with experience and training. You could spend thousands on a 'quality' milling machine and still not get 'precision' if you are not skilled enough.

One of my other pastimes is cabinet making. I often get to hear the comment -'oh, I can't cut a straight line', while I can cut a precision dovetail by eye with the same saw they are using. Those novices then spend a fortune on Lie Nielson tools but still can't "cut a straight line or plane a surface flat".

Manual machines are just that - manual, you decide on the settings and you control the cut. The ability to make lovely things accurately is called craftsmanship and you can't buy that.

Best regards

Terry

Why do you need books these days? Youtube is chockablock with videos on all machining processes. TomOl

But the books we discussed also provide free plans and specific construction details to help encourage the inexperienced rather than generic machining tips of the videos you mention which are of more use to these with some basic experience. It's also easier to scan or copy a page of instructions and drawings to take into the workshop than rig up suitable viewing equipment and then scan back and forth in a video to try to find the bit you need. Books are relatively inexpensive, pleasing to browse at leisure, are long lasting and still have a place and a role to play,

Regards

Terry
