Thread: Surface plate stand |
21/11/2022 20:52:48 |
Posted by Steve355 on 21/11/2022 20:16:13:
Well, thanks for all the contributions. I made a stand at the weekend. The choice now have is to use some bolts, head upmost, to support the plate (with some thick felt pads like one uses for chairs), or I have a 4mm sheet of steel I could place on the top. The plate seems to be designed for the “Bessel point” arrangement, as commercial stands are available for it (at great cost). I’m currently considering using the bolts.
Have you considered using adjustable height feet, but inverting 3 of them, rather than bolts and pads.
The 4th one out of the packet, the correct way up, would ensure that your stand will always sit firm on the floor if it's uneven.

Lots of other sources, and sizes, are available.

Neither CBN nor diamond, but I use one of these from Axminster.
Cheap enough, but unfortunately out of stock at the moment

If you're anywhere near Buxton, Derbyshire, drop in, have a brew and try one.
It works well enough, but I do miss having a clutch.

Thread: bandsaw / jigsaw |

Posted by nigel dale on 14/11/2022 17:59:50:
Hi, can anyone recommend a small benchtop vertical bandsaw if such a beast exists ? There is the Cowells 375 jigsaw which is eye wateringly expensive for what it is, does any one have experience with this ?................
Yes I have a Cowells, and yes it's expensive, but also very good.
There's a whole variety of similar spec, but cheaper machines, but I've not come across a comparable sized bandsaw in the UK.
I have one of the smaller Burgess BK1 saws, and it works fine for sheet materials, but too fast really for sheet steel, even with the speed reduction kit.
My larger Emco 3 wheel saw is better built, but also too fast for steel, and well outside your preferred size.
Several folk have mentioned the Femi, or portable bandsaw route, but again maybe too large for you.
I have seen an advert for these, but no personal experience, of either the saw or UK availability, but they do look quite neat, and the closest I've seen to what you may be seeking.
https://www.micromark.com/mini-powertool/-saws
The photos look quite similar to the Proxxon, of which I again have no experience.
https://www.proxxon.com/en/micromot/27172.php
Note that the US one has a water cooling kit, which might be something to consider making if you compare the two saws.

Thread: Help needed with stiff Pratt Burnerd 3 jaw chuck. |
13/11/2022 21:37:01 |
Posted by Dave Halford on 13/11/2022 17:34:42:
These are the test figures.
Measured at the rear of the chuck runout is at most 0.001” but this rises to 0.004-5” just behind the chuck jaws. With a 1” ground steel test bar, runout close to the jaws is 0.006”, rising to 0.012” at 3 inches from the jaws.
The jaws look to be 1 thou worse than the chuck body, which is pretty good for a three jaw. BUT it gets progressively worse at a rate of roughly 2 thou per inch. So a max length10" long bar following the 'leave on the stock' approach means you need to remove 20thou before a fixed steady will work properly. This can put you into buying the next size up bar.
I wonder if the back of the chuck isn't quite reaching the flat front of the register all over the circumference, and whilst appearing home, is actually cockled slightly.
Have you tried lightly stoning the back of the chuck to remove any dings or burrs?
When I received my , new to me, Warco 1330, the chucks did show a little more runout than I'd hoped.
Some Micrometer blue, and careful use of an internal bearing scraper on the inside of the chuck's short tapers.
One thing I tried was a narrow slip of aluminium foil in each of the three gaps between the pins. The subsequent different bruising on each of the foils showed that the chuck was sitting slightly unevenly.
I'd already blued the taper on the spindle register, to make sure there were no protrusions on that; there was one or two, which I lightly stoned down.
This allowed each chuck to pull fully home against the front flat part of the taper.
Also, I did the same as you and picked the best of the 3 pin locations and marked each chuck so it would be replaced in the same orientation each time.
When fitting a chuck even now, I get best results by partially tightening pin1, almost fully pin2 and fully tightening pin3; I then go around again to fully tighten them all.
Each chuck is actually quite a tight fit on the short taper, such that it needs a sharp tap with a nylon mallet to remove it.

Hello and welcome John, have you spun the lathe up under power?
Those drops of fluid look like they are on the splashback as well, so i wonder if they have come out of the lathe chuck?

Thread: Modestly priced ER collets |

Posted by Michael Gilligan on 08/11/2022 13:49:04:

Not very different, I suppose
… except that the Aim ones are listed as Qty.3
MichaelG.
I think someone has been cutting and pasting carelessly when they were creating the various listings.
Head for their shop and search for collet, where you will find a variety of titles and descriptions.
Some specify 1pc, others have 3 in title and description, others no quantity in the title but 3 in the description, and some say 1pc in the description.
The ones with 3 in title and description seem to be more expensive.
I think some of the ads have been re-worded since I looked earlier today, so some of the corrections have been re-corrected incorrectly, or something like that.
They also list sets of 3 collets for router/trimmers, so that might be where they have confused themselves.

Thread: Quick release rear tool post |
07/11/2022 18:09:55 |
I'm not sure whether this helps or not.
When I bought the Warco 720, a Myford S7 clone, it came with two unnamed Dickson style toolposts and 8 holders.
I made a raising block for the rear, so I could use it with an inverted 12mm carbide insert slotting tool, as well as my normal 10mm insert tooling in the inverted position.
I can also use my normal tooling the conventional way up, and still get centre height OK, for use running the lathe in reverse. As an example I could use an internal threading bar, on the reverse side of the workpiece to cut away from the headstock.
This will of course depend upon the height of your actual QD tool block.
In my case, both the toolpost and the raising block are nominally 1½" high; in reality I think they are about 10 thou over.

Pantograph engraving machines in some cases I'd imagine.
i.e. Taylor Hobson amongst others.
I can even remember Timpson making labels, on laminated plastics, using smaller versions in my youth.
I've still got some of the laminate, but no machine to engrave it.

For those with an interest in electronic pendulum clocks, Light Straw hosts a page/chapter containing all sorts of interesting stuff
https://www.lightstraw.uk/gpo/clocksystems/pages/docindex.html
Every line on this document index page takes you to the relevant TI. (Technical Instruction)
Light Straw replaced Battleship Grey as the paint colour for many items in old GPO and later BT telephone exchanges.
The common Type 36 pendulum clock, as used in Strowger exchanges etc, was expected to be accurate to less than 8 seconds per week.
https://www.lightstraw.uk/gpo/clocksystems/pages/b1001.html
In practice, the one I had hanging in my previous house, still to be installed here, was probably good to a minute or two a year.
I almost only ever altered the time on it for BST changes.
There is also documentation on 3000 type relays, and their identification and adjustment. B5144
I never did do the relay bashing course, as it was just before my time as a construction engineer, rather than maintenance.

I put my Omega seamaster automatic in for service, it took 10 days and when it came back all the bright surfaces on the machanism were all scratched. also they had lost the regulating screw saying it was fine and not to worry, for £100.00 fee, this was in 2004, I have to say that the Omega has kept worse time than my digital watch since!
Pick your watch repairer with care!
This place keeps on popping up on my Facebook timeline as an advert; not sure why, I must have been looking at watch stuff a while ago.
Some nice repair/restoration photo documentaries on this page, including one of a Seamaster

I'd never heard of one before, but see P7 of this pdf, apparently named after a Mr Gedge

I'm familiar with flats on Master Links on lifting gear to slot on knock through chain couplings, but never thought about it for locos. Various photos of those HERE as an example.

Thread: Over / under size nuts |
02/11/2022 20:42:47 |
Undersize and strange size nuts and bolt heads are sometimes used on motorcycles, particularly where there is restricted access.
It also allows a smaller collection of tools in the supplied toolkit, though that might not be the main reason.
e.g. in metric I'm used to 10,13,17,19mm spanner sizes for 6, 8, 10, 12mm threads, but several Japanese bikes use 12 &14mm spanner size, for both under and over size headed nuts & bolts.

I'm a bit late to the party here, but my preference is for Faststone Image viewer, the first one on the list, rather than just the resizer.
Far more powerful than just a resizer, though it will happily cope with a whole folder of images at the same time.
It also works as a basic but comprehensive image editor, and allows text overlays etc.

A good friend of mine, and lodger at the time, used to work in software support for a firm which provided specialist software for various garment production companies.
One day a customer was having some problems, so she asked for a copy of the data they were inputting.
A few moments later the fax sprung into life with a copy of the 5 ¼" floppy disk.
Yes it's true, not an apocryphal tale.

Thread: Test dial brand query |

Julius, where are you in the world?
Outside the UK by any chance?
I ask due to the spelling of Jeweled with one L rather than Jewelled; both are valid in the UK, but the latter is more usual for stuff produced in the UK, as opposed to produced for the UK market in the far east.
The logo on this one doesn't seem that well defined, so I wonder about the quality of the movement.
That said, it all depends on price and local availability.
There may be a small lever on the side, often black plastic, to reverse the direction of lever indication, push/pull; from my own experience with old ones, make sure it hasn't gone brittle with age or cutting fluid contamination.
They are hard to find replacements, and a bit of a pain to make.
