Stove number three

It is "Pablofest" this weekend which means I have a full weekend in the workshop with no scheduled interruptions.  I could have done any number of useful jobs but I chose to practice my welding and use up some of my scrap.  If I don't use up my scrap some one may mistake it for rubbish and throw it out.  I have had a compressor tank I found on some ones hard rubbish pile some time in the 90's.  I had always meant to build a compressor but that didn't eventuate so I tried to sell it on ebay but no luck.

Rather than throw it out I decided to build another wood stove.  This one has a vertical fire box leading into a horizontal cook top.  The tank sits on a tripod so it is nice and stable and has an air intake and ash ash dump controlled by simple gate valves.  There is a removable hot plate which can be used to load fuel and a couple of small holes so you can watch the flames flicker.  I have a removable fire grate that sits in the base at 45 degrees to maintain a good air flow.

Seems to work well.

Wally Mounster

There were a number of very nice small steam launches at Hobart but I had never seen or heard of a steam outboard motor.  This particular example was was for sale and was designed and built by Wally Mounster.  Wally was a local Tasmanian who seems to have been a bit of an engineering legend and deserves a mention in the Tinkerers Hall of Fame.  The other steam launches were also very nice but a bit more conventional.

Rolling lift bridges of the world - 2

Imagine my surprise on arriving at Hobart to find a rolling lift bridge almost identical to the one in Auckland harbour.  In Auckland I had no idea how the bridge worked but this time I had a basic understanding so I made an effort to photograph the important details.

The drive shaft and pinion.

The rolling rack mechanism.

The photo of the steam crane is gratuitous.

The Steam Yacht Preana

Riding in the luxurious saloon of the steam yacht Preana is not the boating experience I am used to.  For me it was almost claustrophobic but a fascinating opportunity to see a steam launch in action.  The boat was originally commissioned in 1896 by wealthy Tasmanian flour miller and parliamentarian William Gibson.  She is a 55 foot launch originally powered by a 60hp triple expansion engine but has been restored and fitted with a 40hp E compound engine from 1905.

The Yukon of Copenhagen

My personal favorite of the Hobart festival was the Yukon of Copenhagen.

A Danish fishing ketch she was bought, as a wreck, for a case of beer and then rebuilt with Danish oak and Swedish pine.  As luck would have it she is now for sale so if I had a spare $490,000 I would consider buying her.  The Yukon web site shows her as 17 meters but the boat sales site says 24 meters so I guess she is between 17 and 24 meters.  I enjoyed hearing her story from the captain but I didn't think to ask how a Danish vessel got the name Yukon.

Hopefully I'll get another chance to get on board and ask.

Hobart Wooden Boat Festival 2015

Im back from three days in Hobart with enough photos to keep blogging for another twelve months.  It would be a tough call to name the prettiest boat in the festival but this Herreshoff pram would be a contender.

Bean rock lighthouse.

I am back from NZ now and and getting back to normal life.  I had a lot of time in Auckland to watch you tube instructional videos and practice my drafting skills.  I had a crack at drawing the bean rock light house with Rangitoto in the background.  The lighthouse was erected in 1871 as a response to increased shipping servicing the gold rush and is an Auckland icon.

The other memento from my trip is a copy of The Dinghy Cruising Companion by Roger Barnes.  I enjoyed read his collection of articles about boats and sailing.  Stories of his sailing misadventures probably wouldn't entice a novice into dinghy cruising but if you are already a wooden boat tragic they are a good read.  I was most interested in the details of his Francois Vivier designed Ilur and the amount of electronics he has packed into a 15 foot open boat.
