Thanks, Zan

I do have another 'take' on the pin or no pin dilemma, but I will save it for later … there are domestic chores to be done.

I use neat cif to clean the bench tops and epoxy coated floor with a damp cloth. The muck grease and pile just vanish

… It all depends on providing an effective spindle lock. …

.

I am genuinely confused, Zan

Can you please explain how locking the spindle can affect the ability to tighten a collet into its taper socket in the spindle

Thanks

The mill is going on a 4" high wood stand with 1/8" aluminium corners to spread the load. This is the maximum we can raise the machine and still just miss the cross bracing for the mezzanine floor above. I'm a great believer in saving my back and the backs of the other oldies who will use it. Short people can make duckboards.

At risk of upsetting the purists, I have bought some cans of lawn green Plasticote paint. It is slightly brighter thanTS green, but still has a touch of the grey-green.

Sounds like you need a refund……

the spindle speed is ok for aluminium 385 for steel with a 4 flute hiss cutter

That’s why I wouldn’t consider any miller without R8 tooling. It allows minimal overhang the amount with a chuck and the tool can be surprisingly big. The quill is for drilling, but it makes it easy to set the z axis. Lift the table to 90, drop the quill with tool onto a 10 thou shim onto the work plane, lock quill, drop table. Remove shim. All now zeroed. Not so easy without the quill. It is in constant use. Makes jig boring possible as well. Tp

 

For machine with a knee or without a quill check there is no droop of the knee ( slack/weather in the dovetail?) this is a common problem with well used machines. I had a friend with an elderly Bridgeport, when the knee was locked the table lifted 15 thou but it was fully and correctly fully adjusted. Still did nice work, although the knee was for position only, the  quill was for adding cuts  . Only possible with a fine down feed , not rack and pinion but with possibly a worm n wheel.

 

i had a nice Rishton mill great,accurate but no fine feed on the quill only the capstan, I  sold it because of this..shame  now I would now have converted it to cnc…..

I have the 8” with plates. Don’t use the plates often but easy to fit,  otherwise they normally they get  in the way but ok when used.  I would have liked it to work in vertical mode, but I have a good vertex dividing head so no problem here.   it’s certainly is a brilliant bit of kit. The thrust bearing under the table is huge. It’s smooth and accurate. Best bit of kit I have. Same t slots as a myford, but parallel 20 mm bore centre. So no mounting stubby morse tapers  but I now have a range of dedicated centres..

a fantastic bit of kit and well worth 5he money Was standard kit fir Bridgeport’s

Hi Richard

My magnetic screw driver has been a great help when I've been working with small screw sizes. I got mine with a big set of drive bits: **LINK**.

Zane

[Zane CrowtherParticipant @zanecrowther67531]

I didn't have an alley key that was the right size, so I bought an iFixit driver kit in the end. I didn't want to risk stripping the screw head with a flat head screw driver that only went across two of the points.

If you have not already spotted them, Zander-Heba have drawings of some of the variants at 1:40 scale. Those available are listed on that site under their Prussian class types, G7.3 & G8.2 & G8.3. Tenders attached to these locos were 3 T 16.5, 3 T 20 or 2'2' T 21.5.

If you wanted to model a loco in the 56.2->8 series then you would have to source further information as the boiler is on different mountings being further forward and higher. I think!

As I'm sure you know there are a number of videos of the preserved Tr5-65 (= war reparation BR56 to Poland) on youtube.

I think Zane should inspect the security set as Mine does not have triangles, better safe than sorry.

[JourneymanParticipant @journeyman]

Top of the thread has gone walkabout! First post is Zane asking where he can get a triangular screwdriver to fix his sons Thomas loco. Neils answer is as above and Zane has replied to say he never thought of a allen key.

I tried to paste it in from a list of Zane's posts but the formatting goes to pot.

Managed to paste it as an image.

HI Zane,

If you google 'security bit set' you can get a whole selection – check the type you need is included. The other option is to file down the end of an allen key.

Hi,

It might be worth contacting this precision engineering company to ask for advice and get a price on an oversized collet? : **LINK**

Hi,

There are lots of trapezoidal screws and corresponding nuts online. Maybe have a look at these: **LINK**

Progress. A couple of days ago, Mozilla 'forgot' to renew a certificate, so all (security) add-ons for the Firefox browser were disabled. Gmail has recently thrown a wobbly. Pilots fight and lose against airliners' safety-enhancing systems. Auto-piloting cars crash, for no apparent reason. Algorithms of Byzantine complexity make decisions too quickly for errors to be identified, and no-one understands what the hell is going on. The stock market has a 'blip'. Machine 'intelligence' learns by implementing heuristics it has 'learned' by processes no-one understands or can identify. Therefore no-one can tell whether the AI is correct or not, except by results – when it's inconveniently late for an error to be detected. And some of the mistakes are extraordinary. The prof. of security engineering (how's that for a concept?) at Cambridge won't touch internet banking.

It was nerve-wracking enough sitting in the passenger seat when junior was learning to drive. Luckily, instructions to go slowly were heeded. But how would it feel to be a passenger in an auto-piloting vehicle, with super-human reflexes, seeing all around itself, and making decisions far more quickly than the hapless, half-asleep and de-skilled human 'supervisor' possibly could, and speeding along, perhaps at speeds beyond the ability of any human driver, particularly in a complex environment. And yet the human is presumably expected to be able to take control as soon as (s)he senses that the AI has stuffed up. How relaxing to be a passenger!

And then there's the worrying problem of the AI's 'moral code'. Who gets sacrificed in certain accident situations (eg the owner, in a head-on smash, or the queue of people waiting at the bus stop, if the car swerves to avoid the head-on)? Will you be able to pay more to have a 'protect the owner at all costs' rule programmed in?

Since most garages seem incapable of sorting out existing misbehaving control systems, we can look forward to chaos when our electric vehicles have a slightly intermittent contact somewhere, or a bug that rarely manifests itself…

Progress? It's too easy to build complexity into software. Features are added 'because we can', and it doesn't cost much. But 'because we can' is not a good justification for doing something.

Rant over – for the moment.

I have a couple of Warco machines, a WM16 mill and a WM250VF lathe, and I am very happy with them – I think!

However I was at their open day yesterday. They had a Smart and Brown lathe (not familiar which model, but it did look nice), and two Harrison mills (one horizontal, one horizantal/vertical).

No room for them in my workshop. and it would need a more substantial floor.

But I could have had a excellent pair of substantial quality British machines for around £1500 total, delivered.

So I think if I were setting up again, but also only if I could accommodate them in terms of size and weight, I would opt for larger second hand British machines, if only one could find them at the appropriate time.

I have acquired drawings form the Heba site and started to cad up the locomotive.

I have some questions about the horn block and axle block and would be thankful for some insight into the design. Why the wedge and adjustment screw? Maintanence? take up wear? other?

I have attached a picture with arrows pointing to what I am asking about, I hope it is clear enough.

I drink Kenyan – can be a delicate taste – suspect the mix of roasts has just enough bite from the high roast not to overpower the more delicate low roast which might well be destroyed by a No 4 roast – the local roaster to me was lost years ago – now its either Sainsbury's beans/grind or the somewhat higher roast Waitrose which IMO is not as good.

My father brought me up on Chagga AA from Tanzania. I've found the Sainsbury's Original Blend bean is not half bad as a standard coffee.

Hmm ,yeah, better plan, get a bigger workshop.

My son & I have a bigger workshop, with a mezzanine floor on about one third for storage. 20 x 10 ———– metres, and still not big enough. VBG

Mine is a 5 x 7 metre fully insulated with attic…… and it's bursting at the seams, trouble is there's no more garden left now. hmmm, maybe down into the sandstone?!!!!

Zan: I completely agree, though this assumes one can get hold of a 34T changewheel, as I don't have the facilities for making one myself, at least not yet. I sent a message with the specification to HPC yesterday. Let's see what they can come up with.
