Burl Bowl

While I was shedless for a year, working out of a cramped (uninspiring) garage, I made a start on a bowl from a Mallee (?) burl.

It was an excuse to use the Teknatool Titan II chuck on the DVR XP as much as anything (the chuck was certainly a lot more powerful than the job necessitated!)

The bowl sort of progressed, then was put aside, had a bit more done, then set aside again over a 6 month period.

I found it in the garage the other day, and took it to join the lathe in the shed.  With some more turning, quite a bit of sanding, then polishing with friction polishes from Ubeaut, it finally got finished.

Finished by sanding to 400 grit using the Skilton sander, then polished, first with Ubeaut EEE Ultrashine, then Ubeaut Glow to give it a rich gloss.

Shed Archaeology

I couldn’t progress the pen making very far without the pen mill, and my scrounging didn’t turn it up anywhere.  Probably easier just to get another, and at the same time get one that actually works well.  The designs typically sold I find to be pretty ordinary – they are either blunt and cut so painfully slowly you are tempted to use extra pressure (which can result in chipping and/or burning), flop around inside the brass tube (despite apparently being designed for that pen type), and I can’t think of what other combinations of issues I have dealt with over the years.  Has anyone found a good one?

Heard of sandpaper versions, but not sure where they are sourced from (and what issues they have).  Think there is a definite market for a better way to square off the ends of a pen blank in line with the brass insert.

Standing at the lathe a bit later, in contemplation mode, and heard a familiar tick, tock.  The shed clock.  It was in another stack of crates nearby that I hadn’t looked through, so did the balancing act with them and went for a bit of a look.  Didn’t find the mill (but wasn’t really looking for it) – was hoping to find the tailstock of the Comet II (but it wasn’t there), but did find the other thing I was hoping to uncover: the Nova Titan II Chuck.

I previously thought I had found it, but that turned out to be a SuperNova2 chuck – fooled by the size for a second.  Once I saw the Titan, there was no possible mistake – it is bloody massive!  Will have a look around to find a suitable blank to mount up.

Can’t wait for the day when I can start unpacking these boxes and crates properly, and rediscovering things.

While looking for a better mill, I did find this mandrel saver at Carroll’s Woodcraft.

planetmandrelsaverIt is specifically for pen turning, and doesn’t push on the end of the pen mandrel (which can cause it to bend slightly if too tight, causing an off-centre oscillation).  Instead, the mandrel feeds through the mandrel saver, which instead pushes directly on the bushings.  This means there is no need for the knurled knob either, and therefore no slippage caused by it being slightly loose, and no distortion of the mandrel.  Very interesting.  If the ends of the blank were milled correctly, getting the mandrel saver a bit tight shouldn’t be an issue, as the load passes through the first bush, through the brass centre, through the second bush and into the headstock.

There is a MT1 and MT2 version (both pictured).  Again, if anyone has used this and has an opinion, I’d be interested to hear.  I’m quite tempted to try it out myself in any case.  To now I have used a live centre with a very blunt point with which to engage the hollow end of the mandrel (a sharp point tends to wander, causing a similar issue as if the live centre was pushing too hard).

Wonder what other developments are out there?

Nova DVR 2024

Found some more information this morning on the new DVR 2024 that has obviously gone up overnight.

Not too bad with respects to my (untimely?) purchase of the XP on the same day as the new one was announced in the US. (Whew)  It also sounds like the 2024 is an addition to the range, and not a replacement of the XP.

The top speed has been increased from 3500RPM to 5000RPM, and there are now 10 preset-able favourite speeds, rather than 5.  Onboard capacity has been increased from 16″ to 20″ and outboard (swung head) capacity from 29″ to 33″ (838mm), still with a 2HP DVR motor. (DVR = Digital Variable Reluctance)

There is the new remote control – wrist-mounted and also magnetic so can be attached near where you are working.  On/off and speed control. Compatible with all Nova DVR lathes.

Big news, is the return of

The 5″ diameter chuck monster as the behemoth of the Nova Chuck range

Love that term “behemoth”, but not to be confused with the Polish blackened death metal band of the same name from Gdańsk
