Finished The Mill Master Motorizing

[absinthe]

it took ALOT of reduction (2" to 10" to 3" to 6" about a 10:1) why so many pullys? cause i had em lol

even with the reduction of 10:1 it wont self start so i pull the tension off the second belt and start and "cluch" it in so i might go to an 8" on the mill

i turned a shaft to fit the mill and used a pin to hold it its now 5/8"

 

[absinthe]

the motor is from an old hoover washer i think (got it for free, also all the pullys. money spent only on the mill and the wood )

and i made a "gear guard" from some thin plastic (not the neatest but it works)

Top job absinthe. :super: I take it you are a turner (If they have them anymore? Machinist is the word these days I think?)?
Love the occy strap in lieu of springs. does the same job so why bother with anything else.
You're measuring in imperial mate. Are you a Yank? You do not give a hint of your location.

Great work there mate
but it sure does scare me without guards on it.. cant wait to see the pics with all the guards on it looking all nice and professional like

im an aussie, from sunbury vic..

i used inches cause thats what all the pulleys are spot on and also the numbers are bigger on the rule so its easy to read and nope im a chef.. but i can turn my hand to almost anything (i was even toying with the idea of casting my own pulleys, and pardon the pun)

i might add a guard on one side (as the other will be against the wall) but i need to lift the tension off a belt to start her going so im not going to guard her much..

(oh and FYI the main pully assembly is from a 50+ year old cement mixer style washing machine)

 

[troopa]

Is there anyway you can make a cam or lever to take the tension off the pulley so you keep ya fingers away from the ouchy bits?

I know that loosing your fingers at home doing something you love doing isnt as bad as loosing em at work but still Unfortunatly you need all your fingers for work so you can do the things you love doing at home... Fuggin catch 22s i hate em

I thought the occy strap gave it away Pete, any fitter who did that needs a good thrashing with a wet hop flower !

Imperial measurements? That just shows your age, I still use imperial heaps.

[Sammus]

I'm 24 and aussie and even I use imperial sometimes... just seem easy to say 'about an inch' than 'two or three centimeters'. People look at me funny when I'm discribing something and use imperial and metric in the same sentence: "yeah the table is about a meter high, and the distance shaft to shaft is about 8in" lol.

And while we're in a mill motorizing thread, I'll post a pic of mine. A bit simpler, and a heap more exxy (im one of those guys that doesn't have access to any machining equipment more complex/expensive than a drill)




It's a 920rpm 3/4hp cap start motor with a 1.25" pulley onto the millmaster with a 10" pulley, custom 12x4 bore and key for a cool $55 B) runs like a dream. Uncovered pulleys because I like living on the edge - theyre against a wall now.

:lol:
Looks like I'm your junior then Batz. :lol:
As for the occy strap comment it just shows that I can be nice when I want to be? :unsure: :blink:

Edit ---- mm Sammus not cm. All engineering measurements are in mm (Most places outside of the US) unless of course you are too old to work it out hey Batz? (ran out of smilies mate).

 

[absinthe]

I'm only 27... and the occy strap is only temporary.. the original plan used just the weight of the motor assembly to tension the belt but its not enough.. a spring will be installed very soon

OT, Pete, I believe the textile industry uses cm, got me buggered why mm is easy as.

Amen to that one brotha !!

Took a good part of my thumb off this evening cutting carrots for a casserole I was making for the family and all the 'hangers on' this evening. A bit of a tip, "don't use a carving knife to cut carrots, that's what the chef's knife is for".

Still hurts like shit too, even after a few beverages to calm the nerves. <_<

OK humour me a bit here, 12x4 means??

Where did you get the pulley's from? I am finally getting around to making up a bench and mounting the motor drive system on my Millmaster. Love a thread with detailed photo's.

It means a 12mm bore with a 4mm key way in it.

Of course, why didn't I think of that :blink:

yep 12mm bore and 4mm key. I got the pulleys from Australian Pulley Company in Windsor. Not affiliated yadda yadda yadda, but after speaking to SEC and Blackwoods and about 4 other places that sent me searching in circles and seemed to have absolutely no clue what they were talking about - like power transmission 'specialists' telling me id have to run a series of 3 or 4 reductions all using taperloc pulleys to get that kind of reduction, costing me thousands to setup even for a 500w system. I finally found and spoke to Luke (I think?) at APC and they were casting a bunch of 10" pulleys the next day. They dont normally bore them in that size, but he put one aside for me and did it specially. Got the little pulley (standard 5/8 bore) and belt off the shelf there, total $80. They seem to cast every month or so, and if you're in a hurry they can plug and rebore one they already have (they normally dont bore smaller than 1/2" for pulleys that size)

Yeah Blackwoods, I rang them and the bloke I spoke to was an absolute nob.

I thought it was pretty simple what I was looking for.Gave him the dimensions of the bore and what size pulley's and told him the type of belt I wanted to run or better still told them I would take a belt to suit the pulley they supplied. Spent bloody 5-10mins getting nowhere fast. Absolute nob.

Righto now that I have got that out of my system I will contact APC

Cheers

Luke is the goer, very good with his craft and will probably laugh when another refuge of MashMaster comes calling.

Top job Absinthe, I'll let you know how the washer moter spins up the mill possibly next weekend.

Cheers,

Uncovered pulleys because I like living on the edge - theyre against a wall now.

Thanks for the great pic Sammus it has helped me ,

I was thinking of mounting the motor below the mill, so the belt comes up through a slot in the table.

then it is easier to enclose and guard the motor now repositioned under the table under the mill,

and to cover the 'large pulley' make a simple box guard.

Just a suggestion otherwise it is difficult to make a guard when the motor is on top of the table .
