Well, I thought it was going too well.
I started turning a goblet...
1. Round down the blank with a roughing gouge...check
then I made my 1 st mistake
2. Shape outside of goblet before hollowing. I used a spindle gouge for this but a combination my technique and having quite a square grind instead of a slight fingernail meant I had a couple of quite serious catches. Enough that it then made the blank feel out of true. I reset between spindles and carried on, far too tentatively, which led to more catches. I got out the trusty turning manual (I cant remember who it was by, but it is the one everyone recommends here) and put a profile onto the gouge. It ran much better after that, however I also changed the presentation of the tool.
I'm pretty certain that I caused some weakening to the stem of the goblet with the catches as I had significant flexibility in it after it was done.
I finished off the outside, sanding down to 600 grit however I thought I might have trouble so did not waste sealer or polish at this stage. That could be applied when it was in a chuck.
I was parting off, supporting the cup and stem in hand when it unfortunately let go. Broken stem.
I used the offcuts to make the shape for a baby ratlle and had some good Skew, Spindle and scraper practice with the remains. No pics unfortunately, but even in disaster I have had fun learning.
So, the crux of the question is how should I approach the next one. Here is my plan for the goblet
1. Rough down between Centres. (Including basic finish with my now practising Skew techniques)
2. Part off at approx right length (Allowing for spigot for chuck)
3. Fit in chuck
4. Hollow
5. Finish inside
6. Support with Tailstock (Padded inside Goblet)
7. Turn shape to goblet
8. Finish outside
9. Take pictures and post on forum
Does the above sound logical?
For the rattle, I obviously need safe finishes. Woodwax 22 is safe, but what should I use to glue the 'bung' back in after hollowing out to get the rattle bits inside?
