Casing metres per kilo guidelines..? [ox runners + middles]

Postby Steven_B » Mon Feb 01, 2016 10:42 am

The calculator here viewtopic.php?f=15&t=11069 has disappeared and the table on that page only covers casings with diameters up to 32mm.

I cannot find any guidelines regarding the filling capacity of ox runners (40-43mm) and middles (50-55mm).

Can anyone help?

I can't say that I've checked, but a ballpark figure would be around 1kg per metre for the 50 - 55mm and 1.5 - 2kg for the 40 - 43mm.

Hopefully, someone else will be able to give a more accurate figure.

Hmmm, Looking on Syracuse Casings site it says 100 yds of their 42+ mm casings will stuff 130-150.
So if I'm converting right, that would equal 91 meters and will stuff 60-68 kg's or 0.64-0.75 kg per meter?
does that seem right?

,...but the list on the link that the OP posted says 1.47 metre of 32mm will hold 1kg. That's 0.68 kg per metre for a 32mm? Now I'm confused! :( :? :?

Ok to avoid errors in my math here's a link to Stuffers in Canada with metric quanities
32-35mm 90 meters holds 40 kg
http://www.stuffers.com/product-p/hg36na40.htm

And 40-42mm 90 meters holds 57 kg
http://www.stuffers.com/product-p/hg42na40.htm

I hope this is helpful

Thanks Dan. I wasn't questioning your maths ability, or that Stuffers website says what it does. But the casing suppliers seem to have very different figures for the same thing. Just the two I looked at have 9 metres producing 17kg or 20kg.

These links may help:

http://insca.org/index.php/en/natural-casings-hog

https://books.google.co.uk/books?id=y9L ... ty&f=false

The bottom one has 3 or 4 pages on the subject and is very good.

Hope this helps/

It was me who was worried about my math, no problem Phil. I guess some hands on research is calling me if that helps ya steven-b. I'll be stuffing 29-32mm this Saturday if you want me to measure it out.

And thanks for the links Phil the last one is very interesting. might have to look into getting that book.

Yes, I was quite impressed with the detail as well.

I did some working out with Excel (taking into account the 10 per cent adjustment for knots mentioned in the table) and - as it happens - the two sources are reasonably consistent.

In fact, it is the advice on p. 30 of the Google book that seems to be a bit wild (well, a little on the ambitious side) suggesting that 17m of 60mm casing will hold around 38Kg of filling.

Here are the figures that I worked out...some rounding and estimating was done but reasonably close for making comparisons. As I said, it's the book that seems to have the odd value (unless I've got my maths wrong!):

My image of the figures that I worked out won't appear in my posts... first time I've tried images on this forum...hosting site is Picasa and privacy is set to public... can't find any useful advice in technical issues. I'm pasting the image url into the <img> codes.

I'll try again tomorrow.

Thanks Dan.

Don't go out of your way to do that, I've got a fairly good idea of what to expect from the information that yourself and Phil have provided.

But if it's no trouble, it would be interesting...

Thanks for all the info.

I loaded your picture Steven:

https://picasaweb.google.com/1111855700 ... 0148439106

...but it's not really comparing like for like. Extrapolating the figures for a 43 or 55mm casing based on a smaller one seems fraught with danger.

i can only say that, if I was preparing casings, I'd work on the figures that Dan Provided, but allow a 'goodly' amount for error!

You can always re-salt any remainder.

Was there a particular reason that you asked the question?

Thanks for doing the pic.

Actually, it's not an extrapolation... I just worked out (roughly) how much filling could fit into 90m of casing based on the figures for metres per kilo in that table from the linked thread.

It's rough because I did some rounding and then adjusted for the 10 per cent loss for knot tying mentioned in that table.

My table shows that there is consistency between the data in the original table and the figures that Dan provided.

---

Why did I ask? So that I didn't waste any casings... but now that you've mentioned that unused casings can be re-salted and stored, it no longer matters so much!

I'm new to stuffing... so there's a lot I don't know!

Cheers

Yes, casings can be re-salted. For small casings I generally prepare 1 yard per lb, or thereabouts plus a bit more for luck. There's nothing more annoying than not having a spare if one splits, or you find that it's got more holes than a tramp's vest!

To be honest, I feel a bit of a berk not knowing the capacities of ox (beef) casings. :lol: :lol:
