having discovered the wood i had ready to turn wasn't suitable for a job on hand and the weather being unsuitable to process some logs outside into blanks I decided I needed some practice turning as Ive not done any for a few months.
A while back i acquired some knackered lignum vitae bowling balls and a jack for a few quid and since I had half a beech rolling pin left over I decided to do a short, heavy carving mallet.
Using calipers to gauge the wood I turned the handle with a grooved (for the glue) 1" diameter parallel section for the head to fit on,copying a handle i knew suited me but adding a bit more meat to the flared end piece since Id found the one I'd used a bit small for my hand.
I then prepared the jack by drilling a pilot hole through the small, inset bone (possibly ivory) medallions on each side. That came out gratifyingly central so I then sanded one side flat to make a surface to work from that will be butted up against the wider part of the handle..
A piece of scrap board was taped to this flat side to avoid drilling into the bench and I then used a 25mm Forstner bit to drill down the pilot hole from the still rounded side through to the flattened side. This wasn't as difficult as I thought ti would be, having done the last one with a brace and bit, but using a new, very sharp, bit in a power tool probably helped.
Using a sharp pointed bit of metal I scraped grooves into the sides of this hole to take the glue and then gently sanded the 1" diameter section of the handle until was happy it would be a good tight fit..
To make it easier to clean up I put a collar of masking tape around the handle and then, having smeared on plenty of the same Aliphatic Resin glue I use on my silly balsa planes ( its water and fuel proof, shrinks very little at all and is very strong ) I hammered the head onto the handle, wiping off all the glue that was forced out and then, using a disposable collar I made with the 30mm Forstner bit and a scrap of wood I've clamped the head onto the handle while it drys (8 to 18 hrs)
Tomorrow I will turn the head to the shape I want. Since I want to keep as much weight as possible I'll be removing as little as possible. I will not be using a wooden wedge to hold the head on, that would have made it quite difficult for me to turn the head in the way I like to work. Once it is turned and sanded to my satisfaction and the ends trimmed to shape I will soak the whole thing in a tank of BLO for a few days which will swell the wood and add a bit more weight. I could add a metal wedge but since the larger mallet I made in the same way from a full sized bowls ball a few years back and which I used a lot hasn't gone loose in the slightest I doubt I'll bother..
More tomorrow.
