Gears, cogs and sprockets

These should come in useful for my next creation - maybe grafting the crane onto an SP5 with a chain driven power take off?



Will be putting a few of them intothis little fella . . .

Looks good Mike! the bottom two look almost identical (if not) to an SE2 countershaft?

I agree with the SP5 crane. You could definatly lift a lot with that

Aye they do! The brass quality is superb!
Lewis

give it a try mike but you will need some chains first

Maybe it's something Darren should look for? as his SE2 is missing one .

those cogs do indeed look interesting Mike! you can have a lot of fun tinkering around with them .

Just tried a sprocket on my SP5 crankshaft - the shaft is too thick - I may need to drill out a sprocket! B*gger!

I had the same problem when I went to put a bigger pulley on my SE3 so I had to abandon it for the time being........
Griffin

Some really useful cogs there, you will find loads of uses for them.
Sandman

These are the cogs, gears and pulleys ect. that I got this morning.

I'm well pleased with all the brasswork.

SPOKESMAN

Some useful pinions and worm drives there SM.
Wallace

Wow, great stuff guys.

Love all the cogs and pulleys. Come in very handy with steam as Mike's shown.

Pity the stuff is so dear in OZ.

Well may get all my stuff tomorrow, at the earliest.
More likely Monday though

Really??? So an SE3 flywheel won't fit a meccano axle?

Wonder how if others do?

I just looked at my lineshaft and assumed it's pulleys and flywheel would fit meccano axles, but haven't tried it. Esp when the lineshaft box mentions meccano.
Thought the lineshaft pulleys were larger than a SE3 pulley too, but they are same size diam wise, not sure for axle fitting though.

Hmmm, might have to check this out, as I was going to order a Mamod flywheel for my meccano.
Don't really want to have to buy a Meccano repro flywheel, too dear

Ill check this evening Wallace. I can drill out one of the sprockets - the shaft must be the same diameter as the MEC1.

A meccano pulley will not fit on an SE3! I've tried several

There we go . . . So I need to start drilling!!

Yup i'm affraid so!

The thing is, the SE3 crank is much, much thicker than a Meccano axel.. so You will indeed have to drill a bigger hole to put one on

I need to do it myself, so I can test that dynamo again
Wallace

I'm Learning something here.

I forgot about the MEC1 Mike. That will definitely take all Meccano pulleys.
My guess is SE2' and SE1 axles will be a meccano axle size.

Well I really hope so anyway

Best check . . . .

1950s Mamods had much thinner axles/crank shafts.
SPOKESMAN

Managed to shoe horn a sprocket onto the crankshaft of the SP5. Had to drillit out to 5mm, instead of the Meccano standard of 4mm. The sprocket was then filed at both ends to aid the tight clearances needed! All the securing nuts were changed to grub screws - the tolerances are that tight. With a bit of luck I may graft the crane onto the SP5 and have the engine connected by chain - which will not slip like a belt, but allow me to mount another sprocket lineshaft on the crane, whilst using the holes infront of the engine plinth to secure everything onto. Just about impossible to get a cog on there and take a drive off it - nothing to bolt onto.

At least you got it on Mike . Now you need a sproket chain

Got my eye on a few MM - it took me 3/4 hour of tinkering to get it right. I had to make sure that I leave room for the chain too! The flywheel now has about 1-2mm clearance on the LHS when viewed from the top.

That's close, but the pistons should hold her straight . I wonder what you will be able to lift with that beast?

An SW1 - I have not had a chance to steam the engine with the new cord on it - willtry over the weekend perhaps, really a need a ton of Meccano to build an entirely new one on the SP5 - but that's going to cost a packet.
Mamodman123

What you need is a couple of job lots Mike! that will get you started anyway! although you can never be guarrenteed you'll get the bits you need

Aye - I need the French Meccano and loads of gears and shafts.

Yes, you can never have too much of the stuff if you ask me!. You never know when you need a small part which you just might have tucked away somewhere.

I bet building this new SP5 crane will take a while!

Just won these - should be very useful . . .

Aye they are quite sought after . . . .

I got the Gears Set B for Christmas probably in 1965 or 1966, and I've still got it. It looks exactly like those eBay pictures except that the box lid (the only thing I've lost) was different. Its a very useful set... goodness knows how many things I've made with it!

Nice MIke, very cheap too

Looks to have the axle with the "slot" in it too. If it does, then very handy and a extra bonus

1958 gears outfit B. Should prove to be a very useful aquisition.



Excellent instructions for ideas to incorporate gear mechanisms.




Safe to say this clean cut young chap hasn't got a 300 a day crack
habit . . .
Wallace

LMAO. Yup they always used photos or drawings of the perfect child for meccano booklet instructions.

Though the father always had a pipe hanging out of his mouth.

Great set there Mike, very nice. I see the dog clutch in the instructions I tried out
SPOKESMAN

Will be trying out a few mechs there thats for sure.

Makes me wish i still had my mechano sets from christmas 69, but alas as most things,they dissapeared

yeh that would be good nice things in there
SPOKESMAN

Been messing around with the gears set, will try and work my way thru the Manual.

A differential . . .



Mamodman123

Wouldn't like to get my fingers caught in that bugger

Nice work Mike anything else in the manual of any interest?
MTA

looks very complicated...

Loads - I'll be trying them all!

PS it work very well!
Wallace

Very nice Mike.

Simple idea too. Almost exactly as a real diff.
