Ok ....things are moving , so far I have ordered a pulley off aliexpress   ,a 1" bore x 69mm dia b section double pulley to match the pulley on the mincer ...which is 300mm in dia . Also ordered off amazon a two foot length 1" dia carbon steel rod with a ¼" key way .
The rest of the drive I have scrounged up and is a pair of 1" pillow block bearing mounts( needs new bearings ) a 320mm dia double pulley ( ancient bi-lock sorta thing ). I have a water blaster ( donated by Eddie 🙂) chassis to mount motor and mincer to . Pix below

The shaft in the image is about 2" to short 🤬 but the one on order has the key way so that solves two problems ( 150 bucks on my doorstep ).
Now just gotta get some angle and start making mounts and brackets . More to come 😁

Well I did think maybe I could mince berley for any locals wanting to process their frames etc ...but I gotta see just how well this thing works 1st . The plan is to over engineer my part a bit but the mincer itself is an unknown at this point .😁

Nice. I need a berley mincer. I'll watch this

Heres my mincer , I bought it like this , a trademe special .Its a little bit slow but does the job.

Got some self aligning bearings , mounted the motor and (power)wire brushed the big pulley .


Unbelievable just how muchs hit you get covered in with the wire brush 😆

😁 why thank you Krow 😆😆
The guy I bought the mincer off reckoned it would take 9hp to drive it . Tbh I couldnt get a lot of sense outa the guy but after thinkin about what he was saying I think he was trying to power the thing without a decent reduction gearing and thusly needed a 9hp motor that had enough torque to turn the mincer at pretty much idle speed . I have calculated that with my reduction set up of ...primary ( pulley diameters ) of
52mm to 315mm for 6.051:1...and secondary
73mm to 285mm for 3.9:1 I will end up with
Motor speed of 2750 rpm and mincer speed of 116rpm .
Im hoping to be able to run motor at 2500rpm (or even slower )for about 100rpm mincer speed . Google advises mincer should be run at between 80 to 150 rpm but they are talking mincing meat and they are saying that too higher speed will smear any fat and spoil mince   BUT (😁) im mincing fish and other crap and my only real concern is that I dont want said crap being flung all over the place ...so... she'll be right .
Oh , by the way , pix have been edited somewhat ....yeah I removed all the empty beer bottles 😁 .....tell ya what , that Ukrainian (Obilon ) beer is good stuff ...knockin on 10% in a 500ml can for 5 bucks a shot .

Operating Speeds for Burley MincersWhen processing tough bait, fish frames, and burley ingredients, a slow speed is highly beneficial for several reasons:

High Torque: Prevents the auger from binding when processing bones, cartilage, and scales.

Efficient Feeding: Allows the auger to grab and pull chunks into the blades rather than mashing the soft material.Recommended Speeds:

Manual cranking: ~40–80 RPM, depending on your pace and how much leverage your handle gives you.Motorized setups: 60–160 RPM. This is the sweet spot to let the blades cut continuously without burning out the motor.

Speeds to avoid: Avoid using standard drill speeds or high-speed blenders (1,000+ RPM) for heavy-duty burley frames, as they cause friction and can instantly overheat or strip the gears.

Mate uses a chipper and it does a good job. messy but quick and easy except the cleanup. Just need to only use frozen.
