It's a small matter but one that's driving me batty. In my modeling work I
usually have anywhere from 2 to 6 little "medicine cups" [the kind they use
in hospitals] filled with various liquids -- custom mixed paint, glue, paint
thinners, etc -- on the bench and naturally I'm constantly knocking over one
or more of these almost every day.

The obvious solution would be to create a small base for them that's
tip-proof. Conceptually a 1-3/4" square of something like MDF in which
there's been bored a tapered hole that matches the taper of the cups would
work fine -- I've already done this with a straight-sided glue bottle that
was consistently in danger of tipping because the base was too narrow for
the height.

Anyway, I suppose I could drill a straight hole attack it with a rasp. I
could also, I guess, use my bandsaw with the table tilted. Both of these
seem like brute force and I keep thinking that there has to be a more
elegant way. I just measured the slope of the side of the cup and it's ~15
degrees from the vertical so I don't think there are any router bits that
would help much either.

Suggestions welcome.

Do you have a wood lathe? It is a simple matter to cut tapers with it,
checking the fit as you go. Without a lathe I would use a coarse half
round rasp to do the job.
Bugs

I'm not sure what angle it is, but I've seen a drill bit that was designed
to cut candle holes. It might do for what you want (sorry, but I don't know
where I saw it).

You might also be able to modify a spade bit to the shape that you want with
careful grinding of the edges to form the correct taper.

I don't know your skill level or your tool availability. You can
accomplish what you want with a cheap paddle bit (Irwin speed bore
type bit). Grind or file the taper on the sides of the drill.
This works quite well for candle holders too.

How about a base made of 2 layers. the bottom layer would have an
appropriatly sized hole to fit the bottom portion of the cups.

A strait hole will hold them just fine. Don't overcomplicate this.

But not the most elegant! I've done just a bit of googling and haven't

pilot holes, and I've found some larger ones made for metal, but no
dedicated ww'ing bits. I've got to figure that somebody makes them.

Fill spare cup with cement. Leave a threaded metal rod centered in the
concrete. You could do this by putting into a scrap board and balancing
over the cup. When dried, glue some sandpaper to the outside of the
cup. Chuck in the DP and Sand to size.

However, I agree with the comment that you are over-thinking. A round
hole should work fine.

I'll third that emotion. I offered a suggestion earlier only because
the OP seemed intent on having a tapered hole for the cups. I don't
think it is at all necessary.

i love the concrete idea.

standard tapers in machine tooling, including reamers, are Morse, Browne &
Sharpe, Jarno, American National Standard Machine Tapers, American National
Standard Taper Pipe.

After consulting about seventeen cross-referenced tables I realized these
won't help.

large = expensive anyways. You could get an entire concrete truck delivered
to the country.

I've never even tried reaming wood.

what am i doing?

This is not expert advise. If u want, take a paddle bit, and grind the
angle /^\ from|^|. Then, or at the same time, grind a sharp cutting arriss
on the 2 side that touch first as it rotates. Maybe 45°. If you predrill,
maybe with a hole saw, then you are cutting only on the side, and do not
need to retain any front cutting edge. I can't think of the cutting edge on
the face, don't know if thos lips are essential.^---^

Build a tray to hold however many cups you need with a little room
between each cup. The rim of the cups should be just a little higher
than the top edge of the tray. Use a carpet tack, or similar, and nail
the cups to the bottom of the tray, cups spaced as required. Pour
plaster into the tray up to the top edge. Let set, pull carpet tacks,
remove cups (no need to grease them - they'll pop out easily).

Well, if it was me, I believe I'd just use a forstner to drill a
STRAIGHT sided hole that was large enough to keep the cup from
tipping. But if you must match the taper, try a web search on how to
make a wood reamer.

I suggested (again) grinding the sides on the tapered the paddle bit. That
may not do anything but squeek. If you were intent, (not that crazy) you
may have to take a dremel tool, and grind a groove. Grind it on the face,
parallel to the side you tapered, again on the side that first touches as
the bit spins, so that the cutting chips curl around backward and break off.
It has to give the leading edge of the chip encouragement to separate, or
rip. It ain't rocket science. And the difference between failure and
success can be very minor indeed.

I use a spade bit, which I presume is the same, modified to the standard
taper taper for making the holes in candlesticks. 7/8 taper 3/4. Quick
grind job and a deburr was all it took.

After much consideration, I finally decided to try out the new RTV casting
stuff I have. I'm going two ways:

1. I made a negative mold with a bottom section of a cup upside down in a
cylindrical hole. I'm going to pour RTV into this and use the rubber
directly as a holder for the cups.

2. I took some Sculpey clay formed a base and then drove the bottom of the
cup into it to form the master from which I'll pour RTV to make new molds.

Assuming none of this works, I'll probably take a few used cups, cut them
down, and glue them onto a plywood base which I'll use as holders for new
cups.

I'd love to have actually been able to drill a tapered hole into a block of
wood but it's really infeasible and most of the other suggestions are sort
of like taking a shotgun to a fly.

Thanks for all the brainpower that went into this.

Frankly, there were a fair number of suggestions that required a fair
amount of effort and probably buying new tools. I love wood, but I
also love being efficient. Making a holder for paint and glue
cups...the thing ain't going to be looking good for long, so why go to
the effort? The only reason I mentioned a wood frame, was to keep some
wood in the project. Otherwise, I would take the foam box from a dozen
eggs and pour in some plaster around the cups. That's as high tech as
the thing needs to get. You know, a kindergarten project.

I've tried straight holes. Unless the block is almost as high as the

and yet you didn't respond on this thread when I suggested that you add

that's going to solve your problem if you don't like having only a

spaced apart a bit will accomplish the same thing. I quit.

What you want is very easy to make if you have access to a small metal

My friend, also a boater, had a machine shop and came to the rescue.

A universal milling machine is a type of horizontal mill, not a Bridgeport.
You're quite right though, a custom made cutter would be easy enough. Now,

Step 1. Drill one hole (1-7/8") with a Forstner bit
Step 2. Take one paint cup and cut it down to ~1/2" high
Step 3. Glue to the bottom of the hole. This completes the mold

Making the holders: Mix 1/2 oz each of 2 chemicals and pour into mold. Wait
4 hours and remove completed holder.

This ain't rocket science. It's simple, The holders are perfectly shaped
every time and because they're rubber they grip the cups.

Of course, there's still one thing I didn't accomplish: Learning how to
drill a tapered hole! LOL

But we'll leave that for the next time I guess.

If you really just have to overkill this and spend some money, go buy
some chairmaker's spoon bits. They make tapered holes. They also cost
about $60-$80 apiece .
