Today I acquired...........

[25.4_mechanic]

it's a cast iron straight edge. Yanks call them camel backs, the english term is a fishback.

Used as a reference surface in machine building.

Thanks. Brad,

so just like these but much nicer ...

only that this pair is on it's way to me


No, really beautiful that Camel-/Fish-Back!! And useful.

Those are machining parallels. They could be used as straight edges but they are a bit small and it's not their intended use. A camelback/beam straight edge is a reference surface so the level of finish is a lot finer. Scraping is one way to achieve that.

 

[25.4_mechanic]

Scraping is one way to achieve that.

Thanks, Pete.

But this one

seems to be precision-ground (right?), so that's another way to achieve that?

Can one say that scraping is to be considered the highest form of precision surface treatment or surface creation?
I always hear and read it with the flair of great respect and have the greatest jitters about it myself?!?!

Thanks

Carsten

Some repair items for toys,then a pack of bargain lighters and guess what,all 10 work.

A nice birthday present

I've had my flex head ones since 2006 and not broken one yet.

Bought my Christmas gift little bit later but worth it
Speeduino standalone ECU , little step towards a big goal.
It features
Injector control
Ignition control
Launch control
Boost control
Flatshifting
Soft/hard cut rev limiter


It takes signal from camshaft position sensor , throttle body,map sensor, intake air temperature sensor,rev RPM,lamba sensor

It's a good compromise for me
I am thinking to download a T-Jet map and adapt to the engine I'll go to use because have the same static compression ratio .
So no decompression as advised in the dedicated rally car thread I've made.

So I can do everything I need without to much headaches
Maybe found another car

At last, something useful for an Arduino to do.

I am going in!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Wait, a distraction.

A good blow torch.

 

[The_Yellow_Ardvark]

Yes a box.

A well packed box, for 2 items.

 

[The_Yellow_Ardvark]

Right I am free from the tool trap.
I have spent some money. I have had coffee.
I have had cuddles from a busty lady. Plus she brought lunch.
She declined my offer of a Braile test as well.

#
A nice old style vice.

Another Grinding paste tin full and a John Bull Puncture repair tin.

The opuncture rpair tin is pree WW! as the lid in stamped to form the brand logo.

A few hand tools.

A WW2 age lighter.

WW2 age firing circuit Volt meter, working as well.

A Dinky toy.

Usher Brewery Keg tap.

A rock in purple.

Not deep purple.

A Gold Self propelling pencil, with a bit of lead.
Yes it is lead.

 

[The_Yellow_Ardvark]

Oh yes.
A Mamod.

a early forward and reverse Traction engine.
But fitted with a Meths burner.

It has a "Long Boiler" and reused/recycled from an older style engine.

 

[sparkysy]

I have one of those lighters somewhere, is it an IMCO tripplex?
Good lighter!

Those ck? Screwdrivers are one of my favourite handle shapes to use. Dad has a few.

I think they're Stanley. I've got a couple. Blue for pozidriv, red Philips(sp?).

You're right. They're very comfortable in the hand. Did about 10 thousand (well ) screws on glazing strips on greenhouses at one time.
