Thread: Etching brass

I would like to put a 'maker's mark' on a project in brass. […]

Horses for courses, Diane ?

... is it really appropriate to ‘outsource’ the Maker’s Mark ?

... Just wondering

As requested by Vic, in a recent thread:

My ‘eyepiece tube to C-mount’ adapter tubes arrived safely today

They were handled in China by ‘ORANGE CONNEX’ and in the UK by Royal Mail’s RM 24 service.

It appears that system is running exactly as it should.

Is there, by any chance, a copy of the Chinese version available ?

... it would be interesting [and possibly useful] to run that through various translators.

Just pondering ... dont know

I wonder what the legality of putting them in a kerbside Litter Bin would be.

Can the local council object to such use of a facility they have provided ?

Looking at it again, Hopper's description as 'throated' is much better than my misleading one of 'semi circular', so apologies if I've over elaborated it and caused confusion.

No problem, Robin ... I just took it as ‘artistic license’ and assumed [that dreaded word again] that you meant it was just like Bob LAG’s photo.

... I must admit, however, that I would love to see the original Myford [Beeston] drawing for the tooth profile.

The set up is similar to what I have seen in Ghana. The box is the electricity meter.

Thanks for the info. ... it starts to make sense now !
 

Other parts of the Laos grid look considerably tidier :

That’s strange :

I always thought that optimised spring pressure allowed the beat to self-adjust.

I shall watch and learn.

This mechanism on this clock is not intended to be self adjusting.

The pressure of the spring is there to maintain position but allow adjustment if necessary.

Optimising friction means the clock is less likely to go out of beat.

I would be grateful for any suggestions on possible solutions.

The location is : 17°57'21.2"N 102°38'13.3"E

.. which you can easily find on Google Earth

The photos show the new, upgraded, installation surprise

Perhaps one of the experts can identify the boxes ...

Thread: Myford ML10 main screw skating

Very interesting, Rob

... I think we might need one of Jason’s [unless another volunteer steps forward] clever 3D models to explain the requisite tooth shape !

Posted by Robin King on 14/01/2021 12:15:53:

Michael,

Your sanity is our highest priority, of course! Maybe this'll help?

The original manufactured form of these gears is with a near semi circular form tooth machined into the bronze gear circumference so that the teeth effectively wrap part way around the leadscrew. They are not in simple straight cut sprocket form. I can understand that at first sight it might appear that the gears are excessively worn, but probably not so; that's how they were made. Thinking about it and in light of using mine for nearly forty years the only way that the teeth will wear excessively is if the gears are prevented from turning while the leadscrew rotates, either manually or due to seizing, but otherwise they are free to turn therefore wear should be minimal, assuming reasonable lubrication, adjustment, and normal handling. I'd still look at cleaning, adjustment and lubrication as the first steps before investing hard earned cash on a new set.

.

Many thanks for that Robin yes

The remaining issue is ... Why does Myford in Mytholmroyd not supply them in that form ?

From the BBC page that I linked earlier:

“An open, collaborative project known as Ruffle is working to develop software that can play Flash content in a web browser, without requiring a plug-in.”

... but personally, I think the security risks are just security risks.

Thread: Myford ML10 main screw skating
14/01/2021 11:27:57
Posted by Robin King on 14/01/2021 10:32:47:

As luck would have it I've just crated up my ML10 for a house move so can't check it, but I do have the Myford owners manual to hand which has the section drawings and parts lists in the back. On section D-D that shows the upper shaft (for the carriage handle) as part no 228, and the lower shaft as part no 122.

[…].

.

For the sake of my sanity, if nothing else, Robin ...

Could you please confirm the intended shape of the gears ?

Bob’s photos are quite unlike the new parts that are on offer !!

... I have assumed this to be the result of severe wear [from scuffing against the leadscrew when incompletely engaged] but others say they are made that way.
