Thanks for the tips CHJ. It was your avatar picture that inspired me to start segmented bowl turning.
Any tips for making a jam chuck.....
It's a great way to add your own personal input to the appearance of a finished piece and provide additional brain cell stimulus rather than just spinning a bland block of wood.
It's also a great way to use up offcuts of timber without getting over fussy with elaborate designs, you will have a few disappointments at times if wood or joints split, but like all learning curves, noting grain direction and counteracting weak joint strengths with assembly methods becomes part of the satisfaction when it stays stable.
Number one consideration, make sure the wood is dry before glue up, joints in compression due to moisture uptake rarely fail.
If stock is small, place on radiator for a few days before final sizing or if the boss is not looking, place it in the plate warming draw or second oven whilst the Sunday lunch is roasting. Find a friend with an Aga cooker and cool oven.
Regarding Jamb Chucks, just Google or search UKW,
Links like this will give you some ideas.
You mention that you have a chuck, what type and what accessory jaws do you have?
Have a look at
the last few entries in the Projects listing here for some ideas/methods of holding and locating pieces whilst assembling and finish turning.
Think about which areas you had problems with and try to develop a method of working that lets you repeat the process on the next item without having to spend time re-inventing a holding method.
After a few pieces you will suddenly see the light and find a simpler way or order of doing it, so much depends upon what equipment and tools you have, try to develop your existing tool use to do the job rather than going out and buying a new toy until such times as you have several dozen items completed and get a true feel for what you need to progress.
