Spiral egg cup WIP

A while back I made a set of 4 egg cups and just recently decided that as I had sold them I would make some more. This I did and posted them here on the forum. I was rash enough to ask if anyone would like some more info as to how I make them!!



Well, I have finished yet another 4 egg cups and I think that they are multiplying in the spring weather!!


I started off with a piece of 2x2” beech about 10” long.

Find the centres and turn it to round. Then it was cut into 4 equal perts.

These fit in the O'Donnel jaws on my chuck. I turn the base to the required diameter, mine about 1 5/8” and sand to 400 grit. Make sure that the cylinder is running true! The base of the stem is about 1 ½' .


The chuck was changed to one of my old pinch chucks which was modified to fit and the base fitted into it





The egg hole was turned with a ¼ round scraper with the rest positioned just about at the centre mark. I was surprised at just how easy this worked and it left a really nice finish. Just measure the depth and width of an egg cup in you home for the dimensions, but make them as accurate as you can. Mine, about 1 3/4” inside and very little more outside! Top of the stem is about 1 3/8”. This was sanded to 400 grit, bit the actual stem is not important as it's going to be knocked about..


Back into the O'Donnel jaws and the marking done with the index ring

And the diagonals drawn in.

I sorted out a simple jig on my bench drill with a wood 'V' block held between two 'runners' so that I could drill the holes to form the spirals with a Forstener bit and very carefully drilled down to a set depth just below ½ way. The finished article from before on the left was just to convince me that it's worth it!! The spiral candlestick at the back is waiting for the sanding too..

Then back into the 'jaws' for the sanding of the outer edges and the sides of the 'legs'. But after the first I decided that it was easier to hand hold them and adjusted the vac to collect the dust. My Axminster heavy duty flex drive is a boon and easier to control that a Dremel, with the foot control. Much more powerful too. It's what I use for my power sanding with a 2” sanding disk.. Magic!

Then it is back into the 'jaws' for the sanding of the inside of the 'legs'. That's so much easier and doesn't take very long with strips of Rhyno Grip abrasives from Richard Findlay held at each end with a pair of artery forsecpts to save me fingers!! The main thing is to make sure you don't take too much off !!

After a final sanding they were finished with a coat of hard wax oil and then, when good and dry, a coat of intercrystaline wax, BUT be very careful!! Because it seems that they can creep up on you and multiply in the Spring time!!!





All in all, it takes a little longer and involves a bit more than yer standard egg cups, but what a difference they are. I think that the French would say that they are 'chic et à la mode'?


What the hell, I like them..

Hi Jonzjob,
You should be pleased with the outcome well done.
Thank you for going to the effort of the wip.
Regards Rod.

Really good explanation. Thank you for sharing.

[Uncle Al]

Thank you for the great write up and clear photos. I particularly like the wooden collet jaws in the 2nd photo, something to experiment with in the future.

Cheers for the appreciation folks!!

Alan, that pinch chuck was given to me about 15 years back by a very good friend. They are well over 100 years old, box and bronze. They are a treat to use. I have also made several others and clamped them with a Jubilee clip or one of the bronze rings if they were the right size. Easy to make from scrap wood and they work very well. I have shown in the thread about the curtain poles I did.
