The weschenfelder site has several sizes of casing from sheep pigs and cows
Dick strawbridge has a good meat processing book though there is a much better sausage one
" The Sausage Book by Paul Peacock...... ISBN code 978-1-904871--44-6
I got my second hand one off Amazon for £4 ( ish) rrp is £ 12.99
Just read the front cover … Published in association with Weschenfelder .. so look on their website first ?
Do take on board about mincing twice and using iced water when mixing .. I found that standing the iced mix in the fridge over nght made it a bit of hard work so next time I made the sausages on the same day as I made the sausage mince up.
Allow a three or four hours minimum to mince the meats and make the sausages . Always fry / grill a little patty of the minced meat you'll be filling the sausage casings with to see if it is the taste you want..
There's nothing worse than having eight Kg of awful too salty asting sausages
Same goes if you want to experiment.
Now I 'll only only make a small up scale-able batch of 400 or 500 grm. ..Beef , pork, lavender & Russian sage taste absolutely evil to us ………
I made four Kg... Whoops. The dog ate them cooked & cold over several months
Weschenfelder gold sausage mix .. we found it far too salty to use in the suggested amount, but not herby enough if we made them to taste less salty .
Weschenfelder usually enclose a sausage making leaflet but it's wise to ask for one ask when you place an order .
They sent me an email PDF copy of some of their recipes .
I too have an old A701 Kenwood made about 1967 if you google Kenwood spares there are still things like the K beater bar , th dough hook and stainless mixing bowls available . On their spares website they show a sheet of models and suitable fittings still available.
I got my sausage meat mincer and filling tubes off ebay but people know that there is amarket for them so be prepared to pay throughth nose for any . Some are seriously worn out others are in pristine conditions so get a careful look at eh pictures or ask for some that show the points of attachment etc. mine eventually died when the metal casing around the rear of the feed screw spit .
I end up with a £26 cheap sausage making(Italian ) machine that can also handle pasta from Aldi , it has a reverse button as well. It's now had about 60 kg of sausages & 10 kg of pasta put through it over four years or so
