4 pole motor has a speed of about 1500 rpm.
if you want mixer input shaft to run at 250 rpm, you need a reduction ratio of 6:1.
So you need two pulleys one six times bigger than the other.
Bigger pulleys better as you have more belt in contact with the pulley for transmitting the power.

No, but the diesel engine will be running at what, say 1500rpm max? Am I right in saying that a 4 pole motor spins slower?
No idea,,your biggest problem is making sure the drum can turn at the right speed to mix and not to send it round too fast ,,Ive found this with my new petrol Belle ,,flat out it turns it faster than the electric model

That's the rough plan!! Motor at present has a pulley about two inches diameter so will need one around the 300-400mm diameter. Twin pulleys would be ideal!!! To qualify on this thread we may need to discuss circumference and radius of the pulley just in case!!!!

ha ha, maybe use terms like pi, and other mathematical formulae will get you the extra points you need to reside within this thread and not the "other" one!

It's just dawned on me, I had to buy a new 27tooth sprocket for it and bore it out and drill a hole for the drive pin, it was only a couple quid item. Just checked the chart and they go down to 8 tooth but 13 would be the minimum I would get away with to fit on a 1" shaft. That would half the speed IF the chain and shaft can withstand double the torque loading.

Yes it will have to go to the side, idealli it would drive the top shaft to gain extra clearance between pulley but I think it wil have to be on the bottom one to get the gearing just right. I can tweak the ratio with the sprockets if need be

Things should never be thrown away!! Old Lister elavator that's been carefully stored in the nettles/scrap pile for about twenty years has just donated a very handy twin pulley. Got a motor from the 'stores' aswell which has a twin pulley so we will have to tinker!!!

i was posting a bit on the bodges thread but this seems like a better place to post some creations as i dont really do bodges, or at least i try not to anyways.
i made this up for a customer a few weeks ago, his own design ill ad.
the gussets on the q hitch were my own ad on's as he seemed to have more faith in 100x100x10 box than i had tbh.

cheers hi.
yeah, he seen it on you tube and thought it was about the best design.
i honestly have no idea as to how good it ill be but the theory seemed acceptable to me.
a long mouth on it so as the clay and stones runs to the back its supposed to have enough time to riddle it.
ill never see it again id say, or id hope so at least as its went about 70mls from me, id like to know how well it works tho.
in saying that most riddling buckets about (the few there is) are normally a old digging bucket cut up like a sieve, unless the clay is dry they are a bit of a b***s of a job tho.

I see the theory, but the reality may be different, in the right material it will work as you say, but only with just the right amount being picked up. Get that little bit too much in it and it will need shaking just like any other riddle bucket to get the material to circulate. Just my opinion though.:)
Doesn't make it any less of a smart job you did putting it together (y)
 
You ain`t lost your touch anyway lad . Tasty work as always

You any further along with the hook lift trailer?
it saddens me to say it but im not.
its still on the cards but there is a few jobs to be done first, which is going to take some time, i would be doing a bit at her if i had the space but where i have is the main floor of the shed and for the last 12 mths ive been fairly busy in it, im sure it ill die down sometime but its earning its keep so the payin jobs have to get preference.
in saying that only just today did i finally get a nice bit of 200x200x12 box for the drawbar so im kind of still gathering, but id have 80% or more of her now.
i also want it worthy of this thread and not the bodge one so all in good time i guess.
i think id be happy if i had another 3 sheds about here..:D

i have that small garage press to build first tho as id be wantin it to bend some stuff...
i have all the bits for it too.
time is the biggest killer, for me anyways.
we got extra help there about 8 mths ago and my god dose he take up some time and i wouldnt mind, i only do a bit of the work.
i think ill get the burdisio's out soon as i think ive done my bit and as much as i love them, id like my life back sometime.
Its all good tho, it could of all changed 18 mths ago over the fall so im just glad to be here tbh, ill get it all done some day maybe.
one thing is for sure, if i won the lotto, id keep ye all well entertained...:ROFLMAO:

thank you for the compliment.
ill just say,
any pics i might put up here going forward arent to gloat or say "look at how smart i am" coz im not, ive read this thread from the beginning over a few nights and i must say, i do like to quality of work of some if not all of the lads on here have done.
i do like to see a job well done, its a dying trade in the trade.
not too many would see what i do here bar the individuals i do the work for but i do like taking pics.
i also have a horrid bad dose of toolaholick. seeing since i dont have a live audience (and i like it that way) ye can be my virtual one if ye dont mind and i do like any structural criticism that i might of missed or could do better.
id have pics of work done in the last 12 mths but they arent current jobs i can throw an odd job up if time isnt important.


as for the bucket.
your thinking like i am.
the conclusion i came to was that the extra lth of the toe could only aid the process, the overall design of it in practice isnt a bad one, id of done the head plate different but it was what he wanted so thats ok by me.
keeping the design and shorten it up 2' say and he is back to more shaking than he will have to do with the longer toe.
i had it on my digger for 2 mins one day moving it, i didnt take the time to play but as one would expect, its quick about the nose.
