That is really helpful thank you.

Judging from that if I make it 100mm longer and account for the lost room for the piston it should do 5kg a time.

Watch the end of the this video...... he's using a sausage filler with a manual crank handle.

Found one on eBay with a large capacity:

Looks similar to what I've planned but mine will be powered with an electronic piston.

If it works it will extrude 5kg of mix in 2 minutes, then needs 18 minutes cool-down before the next 5kg. Will give me time to get the boilies rolled (wishful thinking with a manual table for now)

Planning on making a conveyor and auto cutter too then after a while get a rolling machine.

My 4.2 kg mix / dough requires 3.6 litres total volume.

So volume = 3.14 x radius squared x length of your tube.

You will need a very wide tube and matching plunger unless you want use a tube of standard bait gun diameter.

Maintain the standard width and your tube will be over 2 metres long.

I will be using a 600mm long, 100mm diameter (96mm internal) aluminium pipe.

The plate for the plunger is 6mm thickness, will give an available volume of 4.31 litres.

Based off the weight of your mix per litre it will fit 5.01kg. Each mix weight by volume will vary slightly but 5kg is a nice round figure.

I am ordering everything I need in a few weeks.

I'll start a new thread for the build, fingers crossed all goes to plan 😂

Not sure if this helps, you may be happy with 5kg capacity.

I have a BoilieBenz extruder/sausage gun...it's takes just under 10kg.
I can try to get dimensions next weekend, all my bait making stuff is at another property

This webpage shows you the new version of the Boilie Gun, mine is not this flashy. There's some rough dimensions on there.

I used to knock up 96 egg mixes and it was quite annoying that I couldn't quite fit it all in the gun in one go...and even to get the 9 or 9.5kg in I used to have to take a while packing the paste down in the tube with my fist to remove as much air as possible.

Basically I'm hinting at go a bit bigger than you think you'll need to make the product less hassle to use

Yeah I totally agree. Over about 3-5kg then a cylinder type extruder would become a right pain as you can't have air pockets in the mix. Trust me the results are spectacular when you do. lol.

That's where the hopper type extruders come in to their own. If I was just home rolling for myself I think I'd actually like to have a mixer, extruder and steamer that just did about three kilos at a time. That would give a nice relaxed one person workflow. Home rolling is meant to be a fun extension of the hobby, not a chore. So I think smaller volumes on your own are just less hassle. Sometimes when we've needed to turn out a load of bait in couple of hours there's been three of us using the machinery. One mixing, loading and extruding. One manning the roller end, changing trays etc. One boiling and rotating the drying baits etc to recycle the trays etc. it's not relaxing.

They look amazing, though quite pricey 🙈

I will probably be making something to aid in rolling out the mix to the right diameter for the tube before putting it in, hoping this will help to remove any air in it too.

If I can't get all 5kg in at one go I don't mind, I will add what's left into the next mix and go again. I will be rolling about 20kg in a day with it once a week so after a few uses I will average how much can fit in at a time and adjust the amount of mix I make to stop any leftovers.

This has got me thinking now do I make 2 different extruders 🤣

A gun for 3-5kg and a hopper with paddles and auger for larger mixes.

It's not going to be much fun holding a 11lb gun while extruding.

I used to make my own sausages and I have a 4ltr stainless jobby. They're designed to extrude wet sausage mix, as far as I can remember they have no gearing, the only leverage is the handle.

The gun will be mounted on a stand and operated with an electric linear actuator.

I am trying to design and build an electric automated extruder and cutter, pneumatic would be easier but I need a quieter setup than a compressor.
Are you sure?

This action cannot be undone.

Yes, continue
