Tax..... ?

David,

I like your centre finder, I never got to make as anything as useful as that during my first year apprenticeship ....last century !!!!

I would like to make one of those...

That device is exactly the sort of project, in my view, that newcomers to our "hobby" could make as it would be useful, quick to make, very cheap to build and a good introduction to metal bashing.

Wow £110 ? When I read that I thought it was a typo!

At least it's gone to a good home Mark.

I would love one of those, but normally they are 10 times what you paid!!

Enjoy the new addition

I can imagine the frustration and disappointment if a beginner tackles a model engine that appears to look good on a drawing but becomes impossible to run when built.

I realise there will always be the odd drawing error on a published design but I would hope that any designer would have actually built the thing first before publishing his/her design...

What about one of the many second hand ones that are around ?, try on line auctions etc.

Some of these were made in the 1920's so getting on to be 100 years old now.

I also live near Cambridge and have never been to this museum.

Apart from the mention on this website I had never heard of the place.

I must make an effort to make the short trip and visit it.

Today I finished my Gibraltar Tool Post to the design of the late, great "Tubal Cain".

Yesterday I finished making all the ball handles for the Quorn Tool and Cutter grinder I am building !

I totally understand there are many who just want to get on a build an engine.

But I wonder sometimes how many new people taking up our "hobby" with no experience in metal bashing actually realise what it takes to finish even a small project?

There must be hundreds of unfinished projects gathering dust where the budding but inexperienced model engineer has bitten off more than they could chew.

I think making simple tools that will be used regularly such as a gauge to set the height of a lathe tool for example, can be completed fairly quickly without having to invest in expensive tooling. This gives the inexperienced person valuable skills, inexpensive to make and gives the opportunity for them to assess is model engineering for them?

I am fortunate to be apprenticeship trained and having several decades of experience but when I am in the middle of a build, i dont decry the need to stop the project to make a special clamp for example. I would sooner do this than buy ready made tooling that may need to be modified anyway.

For example, I am 2/3 the way through building a Quorn, i have had to stop the build to make all those ball handles. The balls needed to be created by a tool that i made to a published design in the ME many years ago...

Hi Martin,

I did the GHT modification to my non powered crosslide on my super 7 and it works very well, highly recommended!!

I haven't done the topslide modification as you have done - that's on my list! How did the conversion go?, I see that Hemingway offer a kit of bits for this.

By the look of those photos the wheel tooth form is all wrong for a clock

A good reference book is Michael Wild clock wheel and pinion cutting, it's expensive but the definitive book on the theory and practice of cutting wheels and opinions for clocks.

Good photos though !

As mentioned before, if the wind stops blowing or its night time not much power if anything, is generated by these green systems of power generation.

The river Severn has the second highest tidal range from low to high tide in the world. It happens twice every 24 hours regardless of the weather, we really should be looking at this more seriously now thanks to Putin.

Hahaha very good - !!!!!

Blow lamp I agree with you with the systemic push away from fossil fuels is definitely going to have serious consequences.

Sometimes in a crisis technology finds solutions, at least it focuses the minds of technologists and engineers, just like wars do!

As for sourcing fuel from non despotic and non-lying regimes it seems that the despotic and lying regimes are the ones that have the majority of easy accessible fossil fuel!

Silly Old Duffer is right! It's up to us (and our engineers) to come up with combinations of other methods of energy rather than oil and gas...

The river Severn has the second highest tidal range in the world....maybe it time to look again at harnessing this.

Around me there is huge solar farm planned, not ideal to look out over but perhaps better that than a gas fired power station.

All I know is that this situation was coming and too many (mainly politicians) buried their heads in the sand.

Just to be clear I am not going down the global warming CO2 thing again, it's the fuel we obtain from unfriendly, despotic, unreliable countries that we need to cut down, reduce and eventually stop.

As an example of no long term planning I am led to believe that Taiwan is a world leader and maker of "chips" the electronic sort. China has been making threats for years about invading Taiwan, has any leader thought about this and built some chip foundries in other Countries just in case???....no of course not!

Something similar with my company IT dept today...

Best one for a while was last week when they were advising us of new security processes..."in the event of your laptop being stolen, email us....".....my question was "how?"

All the best

Derek

I would give it about ....10 minutes !

On my Emco FB2 mt2, I finger tight the drawbar and only a fraction of a turn ( less than an 1/8) with thumb and fore finger on the Allen key is enough to hold it in place.

The special small nut at the top of the spindle and the drawbar is used to release the mt grip

But never over tighten!

Derek

Thanks Hopper,

Yes I agree those pics you reposted of that engine room.....magnificent!!!

Derek

I am finding this thread fascinating seeing both sides of the argument, my problem is when one side appears to have lost the argument they then start the personal attacks.

Can we be more civil towards each other please?

Is it possible on this topic ?

Or is that it is too polarising for each group to be able to analyse each others data and evidence. ?

Otherwise this discussion will just go round and round.
