Just to take this to daft extreme.

Nerf guns.

Soft foam darts.. add

Tungsten Tig electrodes

and for extra sauce lanthanided electrodes ............

No need to do anything daft with the darts, It's easy to make a nerf gun (that fires standard foam darts) which is an "air rifle" or even a section 5 firearm.

I own a nerf gun which would need a license if I lived in Scotland.disgust

Where’s Clickspring. He’s very good but hasn’t posted for ages?

Clickspring posted a short video on his "clips" channel a few days ago, apparently he is busy writing a research paper on the antikythera, which has put his main channel on the back burner, I think there may also be patreon content available too.

A recent discovery for me is 'An Engineer's Findings' which was linked to in one of Stefan Gotteswinters videos.

Not many videos, but very thorough and interesting. His self built press brake is pretty impressive.

Thread: ML7 toolpost - Turns Under Load
15/11/2020 14:54:29
Posted by Dr_GMJN on 15/11/2020 13:26:19:

All, I’m not sure why there’s so much confusion about the spring. I’ve explained multiple times now that it wasn’t fitted during use, and why I temporarily fitted it for the contact tests.

There may be something in the observation about the spacers/washers under the handle. I had to make a spacer to get it to clear the tops of the q/r adjusters, and another washer to orientate the handle so I could actually lock it without any clashes. Clearly with direct contact I’d have one sliding interface at the top end, currently I’ve got three. I might try to eliminate the adjustment washer and then I’d be at two. If I can find a nut I might try that too, and reduce it to one, but I don’t really want another spanner hanging on the board. I’ve already got one permanently on the saddle lock bolt. I guess every little helps.

As Ramon says, I’m also constantly adjusting the angle of the tools, so a pin would only be if use for parting. Then again, parting was where I had the most issues.

Ill re-assemble any test it. I think enough is enough with this. Let’s face it, Skimming the casting by 0.003” must have made an improvrment.

Same toolpost here, I used to have a needle roller thrust bearing on top which helped. Installed it properly with the proper toolpost stud and it got worse, knurling and parting became impossible, blueing showed the contact area was OK, shimmed it with a sheet of paper and there was a large improvement.

Thread: Warco experience - WM18B
03/11/2020 13:04:48

Someone on a US forum had a go at re-writing the chinglish manual for the SINO a few years ago, on the pages I looked at there wasn't any difference...

Once you have the hang of the major functions you will be fine, there are plenty of youtube videos covering the subject, ToT and blondihacks have both done one:

Suppliers of industrial machine tools sell you a support network, with the machine thrown in for free. Hobby machine suppliers sell you a hunk of cast iron and hope you don't come back. If you want fancy manuals and other such handholding it would cost an amount that the market would never bear, same goes for the build quality.

Given how easy it would be to produce even slightly better manuals, I honestly think that UK suppliers prefer things that way as it deters the terminally stupid.

Thread: Milling attachment for Warco wm290vf
23/10/2020 19:46:26

You would need a DRO or the x-axis on the leadscrew will drive you potty. The table size is a masive compromise, and you can't realistically keep a vice mounted either.

I think the only reasons to buy one are either a very specific usage case which fits in the machines envelope, or having no space at all for a mill, as I think it is probably slightly better than using a vertical slide.

I seriously considerered getting a milling head for my 280 but I knew I would just get frustrated with the compromise and stuck out for a mill, it was the right decision.

Thread: Optimum products?
19/10/2020 13:42:52
Posted by Alan Ambrose on 19/10/2020 12:20:14:

Which is an appealing narrative at least...

It's one version of the truth, another is that the machines are pretty much identical to the ones sold by many others and that you would be better served looking mainly at the reputation of the supplier rather than their machines. As above the UK agent is excel who are more into the small scale industrial stuff rather than hobby, so you won't find much experience here, also the optimum mills are priced quite high considering the similarity to other machines.

It used to be the case that (some) optimum mills were machined such that CNC conversion was easier, which would be one reason to look at them particularly, but it has been quite a while since I saw that claim and it would need to be verified it was still the case.

Posted by Dr_GMJN on 21/09/2020 09:57:12:

Personally I'd go for taking reasonable precautions, but use the tools to get things done, rather than just look at them and let them deteriorate through lack of use! It's a fine line between deciding to occasionally use existing equipment for something it not ideally suited for, or not doing it at all.

I take the view that tools wear out, best do something interesting with them before they do. In fact, I hope I wear my lathe out, it'll show I got my moneys worth and I can then justify buying a better onedevil

Thread: Can you reuse old treated Silver steel
15/09/2020 16:13:28
Posted by jaCK Hobson on 15/09/2020 10:19:14:

Q "Can you reuse old treated Silver steel". A yes. Which is what other people suggest but their responses start with a negative so confused me for a few seconds.

I only later realised that the question in the OP text was the opposite to the thread title, obviously I was answering the detailed question in the text, but I can see the confusingness...

Does silver steel have a “use by’ date?

Should still be around close to the heat death of the universe, though our own sun going off pop might mix it up a bit. Long enough not to worry about. smile d

15/09/2020 10:00:16

Not directly from the phase changes in the steel no, this can be repeated indefinitely. The action of heating and quenching on a more macro scale will cause problems eventually with sufficient cycles, and any physical damage accrued while being used as a cutter could also come into play in a sort of stress-corrosion cracking.

But basically, no, crack on.

Thread: Locked out of the lathe
02/09/2020 12:54:06

It's a cheap simple lock, usually easy to pick. You need a tension wrench to provide light torque while giving the pins a jiggle about, the stainless steel strip found in car windscreen wipers makes good tension wrenches though a screwdriver or similar can be pressed into service, lockpicks are typically made from steel shimstock, 25thou to 15thou being a workable range, a single triangle toothed shape to "rake" back and forth would most likely get you into this one.

Loads of videos on youtube, try a search for the lockpickinglawyer for some quality inspiration.

I have picked similar desk drawer locks using paperclips, though I wouldn't recommed that as it is fairly tricky due to the lack of tool strength.

My building society lets you pick from a list of registered numbers for two factor each time it is needed, so I can use the landline when at home. Which is just one of the reasons I barely use the bank I am also a customer of, as they insist on using a text message system.

Thread: Lathe turning speed in relation to different metals
31/07/2020 20:02:03
Posted by Chris TickTock on 31/07/2020 19:36:07:

Hi Guys,

Currently I am going back to machining fundamentals.

Reason: If you don't have a grasp of these you are ill prepared.

So OK you are told different speeds for a given diameter of say mild steel, silver steel, brass or aluminium.

But can any one explain why it is advised to go at a given speed for a harder / softer metal.

Chris

The "best" speed is due to the relationship between the mechanical properties of the material (shear and yield strength, Youngs modulus, etc) and the mechanism of chip formation, also often limited by the properties of the cutting tool.

Practically speaking, it because that that is the speed that "works".

Thread: Quality small metric spanners
30/07/2020 20:20:51

Bergen seem to have been entirely subsumed into US.pro for the moment, the US.pro mini spanners are the same dreadful ones sold by many others, at least they sell them cheap...

A man of fine taste regarding the the ratchets I see, before the last branding shuffle the better Britool stuff was marketed under "Britool England" and included the clutch ratchets, you can see from my 1/4 drive one here that they probably came out of the same factory as the bergen ones.

Otherwise they're not magic and don't tighten and undo ordinary nuts and bolts any better than ordinary spanners.

Dave

It may not be magic but a suitably accurate flank drive ring spanner can, as well as being better for peak torque, reduce bruising of flats in those more aestheticly challenging situations. As Tim Pointed out in his OP, and I agree, you can't get cheap decent small spanners, they are all crap.

Anyone suggesting Britool should be aware that they have been nothing but a branding exercise for quite a while now, and should be treated with appropriate caution.

Also the correct answer to any sunglasses question is invariably Serengeti, I'd pick non-polarised glass lenses in the original drivers tint.

You have to laugh at the snap-on pricing, when you hear of some poor dealership mechanic lamenting about how he had ten grands worth of snap-on tools nicked, I always wonder who is it that nicks half a socket set?

Also thanks to Barrie (and others) for putting those Stahwile 16 spanners on my radar, another expensive addition to my "want" list, thanks a bunch crying

Hi Dr_GMJN, I was sure your username rung a bell when you started posting but I couldn't place it, didn't realise it was from PH until I saw the Stuart build thread pop up in recent posts there.

Nice engine build so far, hopefully she'll run like a chipped 330D laughlaughlaugh.

Re your post on the previous page about indexing, would highly recommend getting both hex and square Stevenson collet blocks from Arceuro, makes jobs like that really easy.
