Taming Turnings in 2010

That looks good Chas

So this is your home-made version of the Munro cutter head? Looks like it works really well. I've been thinking of making something similar recently. Any particular problems making it or is it pretty straightforward?

Would have been a lot neater if not easier had I have had a milling machine :lol:, as it took a bit more personal effort with a file, probably no longer though.

Ensuring you have a method of adjusting the shield, and keeping it aligned when set is crucial.

Careful Chas, that is getting to look more and more like a Monroe with each improvement. :lol: Wish I had your skill,

Very good Chas.
Will we be seeing some hollow forms now Chas :?:

I doubt it very much, just need something for deep hollowing of vases with improved safety.

Looking good Chas. So when will you be selling your new tool (for a fraction of the price of the Munro :lol: :lol: :wink: )

:lol: :lol: Does put rather a big question mark on the Pricing, although I fully understand the costings of scale when casting components etc. for what are fairly low volume sales.

Guess it's not the tool to take along to Yandles or Axminster this spring.

I may try for a slimmer version of the head assembly latter on, don't really know if it will be needed at this stage for my intended use.

Main thing is coming to terms with material strength required. Although in reality the cutting loads are quite low due to the limited cutting depths maintaining rigidity is the priority I think.

This looks very impressive Chas 8) My hat is off to you, my tool making just about stretches to sharpening the odd piece of bar :lol:

Looks good Chas.
Nice piece of Beech,nicely spalted and finished
I'm sure you will get used to the tool over time and with some modifications to it.How does it feel compared to the Munro tool itself :?:
What is the handle made from :?:

Mine is somewhat heavier in use than as I remember the Munro, but operates in the same manner in as much as you rotate the head against the rubbing shield until the cut is picked up.
The weight difference is deliberate, it is not a tool I will be using for long periods and I think the extra weight will provide additional damping. Most of the weight comes from the 5/8" shaft and its length, more than is needed.

The Handle:

• Aluminium tube from a neighbors scrap Dyson (had a ghastly mauve plastic flex hose on it)
  Coiled plastic covered spring flex hose from another old vacuum cleaner as a cover, tight fit. (was doing duty on my router fence)
  approx 150mm of softwood core force fit in ally tube and bored to 5/8"
  tool shaft clamping ferrule and end cap turned from Steel savaged from old farm bale lifting tine.
  Clamping brass 8mm bolt from surplus milking parlor mod kit.
  Knob turned from Oak offcut.
  and a bit of epoxy for bonding

[Steve Jones]

Very nice Chas, I especially like the grain pattern and overall shape. To be honest if it hadn't been for the close up would not have noticed the 'warts and all'

Steve

 

[Bodrighy]

Ah but they are good quality, well finished warts Chas so they are in fact natural features, not defects...think rustic :lol:

Pete

 

[CHJ]

..think rustic :lol:

Funny you should say that Pete, almost reached for the wire brush to enhance the features and Lemon Oil at one stage.

 

[johnny.t.]

.........almost reached for the wire brush to enhance the features ...........

There's hope for you yet Chas :lol:

Very nice looking bowls Chas
Love the natural colouring of the pieces,and the bead detail looks nice and crisp on all.
