Quick Question - gas exchange hole sizes for grain jars.
    #15169015 - 10/02/11 08:48 PM (13 years, 3 months ago)

How large should the GE hole in WBS/Rye grain jars be for multispore/LC inoculation?

I have a 1/2 inch forstner bit and a 3/8ths normal drill bit I can use. I have synthetic filter discs cut up into nickel-sized circles ready to be siliconed onto the lids.

I like 1/4 inch. But 3/8ths is fine

I have 3/8 holes in mine.  You will just have to fine tune the moisture of the grains when you load the jars.  When you do you first batch try to leave one or two a little wetter than the others, and see if it makes a difference.  My house is fairly arid and the grains benefit from a little more moisture.  IMO

This is bad practice.  Drill four 1/8" holes in each lid, but use the whole filter disk.  Don't cut it up.  The weave size on filter disks requires much more surface area than what you have if you simply cut the filter to the size of your holes.  If you do that, you'll have lower performance due to gasses building up in the jars.

Damn, RR, good to know. Most lid teks these days pointed me towards doing the one inoculation port, one air filter port, so I went with that on my first 12 jars. Next batch will be done better. Considering the number of jars, I may do a half-lid approach to save on the dics, but still utilize 3 1/8th inch holes.

Thanks for the responses, everyone. I'm determined to keep learning and honing this process.

i made the mistake of making four 1/8 inch holes then covering each hole with a nickel size piece of sfd. every jar stalled and i wasted a handful of sfds.

These first 12 jars have a 1/2 inch hole with a disc over it, so the holes should be big enough to avoid stalling I'd hope. It's really clean there's no blockage from silicone or anything like that, so a true 1/2 of filtered GE port.

I do like the idea of having four holes evenly spread out around the jar, with the inoculation port in the middle and one big disc over the lid, though.

Another good way to make holes in lids is to use a hole punch, usually the heavy duty ones at craft stores work great, Walmart has one that cost about $3 and is labeled as an effortless hole punch. The best part about using one of these is there are no burs on the lids which can occur with drilling, thus reducing the risk of getting cut.

I have never thought of using a hole punch. That is why I got a forstner bit, but that takes some definite effort. I'm going to investigate that for sure.

This one I got from Walmart works really well, I had tried a dollar store one before and it only worked a couple of times before it broke, this one is easy to punch and I have used it to make hundreds of holes in jar lids. The secret is that the punch has two sharp points instead of a flat round blunt punch (I don't know how to explain it) If I still had the box I could post the UPC code.

I have a horrible time with lids bending when I tried to drill, or lids spinning out of control and cutting me, or holes that were jagged and not uniform. Using the hole punch makes the job much easier.

Yeah, I was using a forstner bit and they're typically done with a drill press due to the nature of the cutting point and lacking a guide. Had to clamp my lids down to a board and brace it with my knee and drill while applying considerable pressure on the drill. Didn't like it.. even though the holes are smooth as hell.

Then again, for larger holes (like for my innoc ports) that is the best option I think. But this hole punch might save me half the effort from here on, and provide better GE to boot! :grin:

a nail and a hammer - quick and effective.  put the lid on top of the ring to give yourself sufficient vertical headroom.  one can punch four holes in a lid in 15 seconds, and it leaves a clean edge on the exposed side of the lid.  ive never tried a hole puncher though.  it seems like it would, uhh... irritate my carpal tunnel, so to say, but perhaps its a lot easier than im imagining?  viva la no resistance?

I use a hammer and a 3/8th drill bit, then stuff it full of poly. Thats all I do. I just did 24 jars today, matter a fact, I just heard the pressure cooker drop and the smell of pc'd wbs has filled this house.

I love that smell.

Why don't you keep the lid on the jar with the ring on while drilling?

I use Tattler lids, drilled to the same spec as PF cake lids: four 1/8th inch holes...  Then I top that with a full sized 90mm SFD.

Here is what the lids look like:

Interesting stuff guys. Never seen a "tattler" lid before, where do you get those? Just curious.

Ok, I HAVE to chime in on this... 

I was reading this post while I was at work (from my phone) and thought what a great idea!!!  Hole Punch!!!  So I stopped at walmart on the way home and bought one, along with a bunch of other supplies I needed....

Well, I have to say...  I have sat here and punched holes in 24 lids so far, took about 5 minutes, and its the EASIEST thing Ive ever done!!!!  MUCH easier than a nail and hammer, and I swear Ill never use a drill for these holes again!!!

Its in there office supply section, walmart part number is "wm-shp01" Click here to view it at walmart.com

THANK YOU XFINITY for mentioning it!!!  I owe you one!!!  :yourock:

I have a drill press and it took me about 1 min to do 24 lids with a forstner bit. I drill through 6 at a time :whoo:

Considering I live in a small apartment in a big city I'd have a difficult time justifying the space required for a drill press. I have a hard enough time finding room for the jars I'm making lids for! If you have access to one a drill press is definitely the way to go here though.

I usually don't feel like busting out the drill. I just take a hole puncher and punch 2 holes overlapping each other. Simple fast, and no need to bust out the power tools.
