Bung borer

Bung borer are a class of tools that bore a tapered hole in a wooden  barrel, cask or flask.
The tool make a graduated tapered hole, called the bung hole
The bung, being made of wood, cork or rubber, having a matching taper will make a good seal.
Often two bungholes would be made.
The first one in the middle of the barrel, at its highest location when laying on its side, which was used for filling the barrel (or whatever vessels)
The second one, with the barrel now standing up, would be bored on one side of the head, near the rim, opposite the filling bung.  That would be the one that would receive a tapered wooden or metal tap for dispensing liquid.

The first models of bung borer used the age old pattern of a simple tapered spoon, later more sophisticated model would appear, numerous patented.

The Swan patented borer

The Brockett patented borer

As early as 1838 they had some patented mechanical contraptions machinery to cut both the bung holes and the bungs.  But the tool in question was intended for use primarily at the receiving end for dispensing liquid.

This is how this one came to be in my shop.

These items, including Rudy, followed me home (Tm) the end :-)

These tools, all came from Beans Antique and Collectibles, here in Wilmot.

Price tags were $73, they gave it to me for $57 tax in.

They changed their pricing by the way no longer everything 50%

Happy for what I got, worth it.  And yes, I'm a good customer :-)

Now let see what I got and why

CW from top

Hand auger handle, Bung borer and matching wooden spigot tap

The hand auger handle is destined to fix a current auger with a loose (worn out) handle)

My new handle appear a good fit, and now I have 

an historical model to turned new ones.

The original on this one (or a replacement) was roughly hand carved, not turned.

Also appears to be a soft wood?

A subject for another post, lets have a closer look at the remaining, related, objects

Rudy getting a closer sniff

See a difference is handle sizes?

That tell you a lot about the force to be exerted between these two tools

It's a yet unidentified maker's wood barrels, cask, bung borer

They were used as such
Ad from the 1880s for Enterprise Mfg Co of PA.

They were an hardware specialties company, better known for their mill grinders.

Top three pics from Etsy.

I do not know if mine is indeed such a model, but I can't see how mine would keep the chips inside the tool??
The one in the above ad has a short thread of the cutting bit (part of it enclosed inside hollow taper cylinder?), mine is longer exposed and there are no way the chips can slide inside the tapered hollow cylinder.

The bit is solidly fixed at the tip, there are no spaces between

 the top of the tip and the inside of cylinder

Other than that the construction appear identical.

Turned hardwood handle is fixed to top of tool casting by one small 5/8 wood screw.

Yes look funky, but that is the correct size flat screwdriver.

Grace tools saw screwdriver, perfect fit.

The wooden spigot I found seems to be a good match.

I suspect they long settled on a "standard" taper by then.

I wonder if it is the same taper used in chair's building?  Because if, so they would make a handy source of tapering tool for chair making.  Expect to pay about Cdn $35-50 for one of these, which is much cheaper than new customs chair making one's.

Construction:

The body is cast then the tapered cone and cutting lips are machined.  Short auger bit is affixed at the end.  Turned wood handle is secured by a single wood screw.

Cutting lip, bottom, is sticking out ever so slightly from the body.

You can see some nicks on the edge.

Take care in sharpening to only touch the inside of the lip, 

never the outside or you risk changing the outside diameter

 and lowering the cutting lip.  If you look closely inside the bottom, the auger bit is peened inside 

A look at the wooden spigot

Made up of three turned parts.

The main tapered part is cross drilled

Internal "conduit" is 3/8 dia

The Bung borer would benefit no doubt from a quick sharpening touch up, but 

let's give it a spin and see how it perform, as found...

Using a piece of hardwood, since barrels are mostly oak

This is harder than oak, but the cutting lips of the auger are not engaging.

In its defense, it is hard to apply much pressure from the height I am using it.

OK, so lets try on soft wood, pine

It kind of work, but it chew more than it cut

Typical mangled surface left from a bit in need of a tune up

At that rate, it would be a while before we get the tapering action involved.  Lets try drilling a hole to start it.

I just grab a bit, found out later, it was a 1 in bit

Forstner bit laying at about the 1 inch dia. on the borer

It is graduated at 3/4, 1, 1-1/4 and 1-1/2 in

The piece of stock I'm using is 3/4 in

Yea, it kind of start a bit high up

After a few turns.

It is easy to get carry away, its fun :-)

Yes, it is tearing going against the grain.

Will be improved after sharpening.

Remember this is "as found".

Now let see how the tap fit.

Simply pushed in by hand.

Pretty darn tight on the inside surface of the vessel.

And this is just hand tight.  In use they would be tapped in with a mallet.

Of course we had tear out on the front face.

But I am pretty sure once wet, this will make a leak proof connection in the back

Which can only be improved by sharpening it correctly.

Just a touch up really.

Interesting find, and now I know how it works.  

Sharpening, is added to my to do list Vol 3 page 6.

Meanwhile...

... Better start clearing out that table and clean up 

my wood chips before she gets home :-)

Bob, putting stuff away while shuffling more stuff

She said YES

We both been married before, both widows and we have decided to spent the rest of our life together.
She wants a regular wedding in the Catholic Church, so I am playing along, and going thru the rituals.  From courting, to proposition, etc etc... :-)

Being always unconventional, I figured we should start with a dry rehearsal of the honeymoon, so I took her off to Cayo Gulliermo in Cuba recently.
On a more serious note, having recently lost her mother, it was a timely and well deserved time to get away from everything.

Infinity pools and the ocean

Of course part of the rituals, included proposing to her formally, by presenting her with a ring.
But said ring had to be presented in a box I was to make, her idea.

Of course the day chosen for propositioning her was today Feb 14th Saint Valentin day, and we just recently came back from Cuba, Tempus Fugit...

From this white beach to ...

...This white beach :-)

That was at Steve and Debbie place, where they were babysitting our dogs.

Debbie and Steve are the other set of grandparents to our grand kids. 

I racked my brain(s) over that box for a little while.  Believed it or not, my first inclination was to dovetailed the box, but being a small ring's box, that was quickly discarded as being a bit on the small and ridiculous side.  Then what??  Looking thru my recently re-sorted box of exotic woods, I thought, perhaps a bandsaw box? or carve something.  If you are used to carve Basswood and then try some of these rock hard exotics (many contains silica, which is murder on your edges), then you quickly abandoned that bright idea.

The other day we gave the dogs their baths and while they were chilling out afterward, I slipped downstairs to try something else.

Found a nice piece of Bird's eye maple, squared off two corners, then drilled a hole with a Forstner bit

Two corner edges are now squared off and I quickly (lightly) planed off a small area on both sides, before drilling.

It is a lot easier to hold a board under the drill press than a small cube, hence my sequence of operation

On my first nite, that is where I stopped, while I pondered where I am going with this...

Yes, Cuban rum and coke :-)

Overnite I tossed some ideas in the brain bucket, and proceed from there.

decided to make a cover from a different species.

Some uncarvable African exotic :-)

The blue/green speckles are remnants of fabric from a previous experiment

The cover was given a bevel around the top edges

Found some suitable hinges.

Would had prefer some thing better, but that is all I had.

The screws were a bit long, so to avoid blowing thru, I snipped the end of the screws

 with a side cutter. 

All my screws holes were pre drilled using my small LV Bird cage awl

I tried various material to make a ring holder in the cavity, cardboard, various density of foams, fabric covered or not etc.  In the end, my best bet was a piece of foam cut from a pipe insulating sleeve.

It gave me the right resilience to accept the ring and hold it.

The box, oiled and waxed

my final product

So this morning, I got on my knee and proposed to her officially, and she said ...YES

Our wedding date would be on Oct 14th 2020, in Middleton Nova Scotia.

Here goes my tool budget for a while :-)

Bob, off to Rotary duties
