Thread: Lift that log!

Hey Bob??



Bob mate you there still?




ooooooh Bob!!




you sorta forgot something mate


uuummmm eeerrr some pics would be good eh?



Funny about that seatainer idea mate... was wondering how your timber stash is gonna handle it when the heat gets up around 35 or more its gonna be more like 55 or more inside that thing unless you got some way of cooling it down that is... thinking most HOT days that will be upon us soon I hope theres little to no breeze for the vents to have any real effect at least till late arvo so its gonna cook the timber isnt it?

RE: Missing Pics: Sorry shane - should be fixed now.

Let's start with a picture.


Two whirlybirds on top to let the hot air out and 6 vents on bottom sides to let outside air in, so while some breeze is good it is not essential for this thing to work. Yep, the air inside the seatainer will get hot, bloody hot, so it expands and rises to the top of the seatainer and out of the whirlybirds (it doesn't matter if they're being turned by the breeze or not), to be replaced by slightly cooler air from outside comming in through the bottom side vents. As long as there is enough air moving through for the moisture to escape it should be OK.

Anyway before I put too much more wood into it I will do some some temperature and humidity tests. At work we have these great little gizmos that look like PC memory sticks that you leave in the location where and for how long you want to test. Then you bring them back to base and plug them into your PC and they tell you the temp and humidty during the time they were on site. I will put one inside and one outside and leave them there for a week or two and compare the results. Hopefully that will tell me if I need to add fans to assist air movement.

Cheers

And where would would someone purchase these gizmo things and for how much Bob?

cool. Handy being employed at a workplace where they have great toys you can use hey?

You will have a shipload of timber once you fill that sucker up Bob! Crikey, I might even have to buy some off ya!.......

Cheers Bob... all is revealed now thanks

Great idea easy and works so a great idea!!

Soooo that crooked bit at the back right side... you know the big bent long there... whatcha gonna do with that? I was thinkin if a bloke were to be buildin a fine big boat that would be nigh on perfeck for the stem Of course then that fella would have to have access to a fine ships bandsaw too... ah well but then I do recall a bloke building a whopping great wooden boat in the bush over east was like you Bob... you know adapted stuff for his needs or invents stuff that sorta thing... an he built a ships bandsaw... so about that crooked bit

Do you mind if we follow up with that temp thing? Ive still so far got the 40ft seatainer out the back and if your idea works then instead of a finishing room it can become a timber drying shed.

Actually thinking about it... you could if you had access to them stick a couple of fans on those vents and belt some air through say 3 times a day for half an hour may help?... or just set them to work with the wind if it comes? I dont know Im just thinking out loud here mate and worryin about all those slabs youve whacked in there instead of bringing them down here for me to mind for you ah well

Great ideas both of them Bob well done mate

This is what we use, http://www.tinytag.info/products/ . They are not cheap because they are designed for operating in fairly to very rugged environments like outdoors, or to be thrown into a box of oranges in Chile and recovered in a warehouse in Europe. That way the buyer can know the likely T/H history of the products.

As usual the prices are overblown in Oz, see http://www.omniinstruments.com.au/pr...ytag.id44.html
The specs on the ones we have are, 32000 readings, 1s to 12 day sampling rate, Temp Range -25 to +85 deg C and Humidity Range 0-100% and they cost ~$450. RadioSpares also sell the tinytag and tinyview stuff.

BUT

For less rugged enviroments and not quite the same specs as the Tinytag stuff, RS sell a neat little T/H USB sensor for $153. Look up Lascar EL-USB-2 RH/TEMP, USB DATA LOGGER

Specs:
USB Interface for set-up and data download
16,000 readings
Supplied with: Software and battery.
Measurement range 0 to 100% RH -35 to +80°C
Logging rate 10 sec. To 12 hours

If you have a secure location where you can also locate a PC nearby you can just run a long usb cable direct to the measuring point and use dedicated T/H sensors. This should be cheaper. Can't find a local example but see http://www.audon.co.uk/th1.html.

These things are really cool gizmos.

Cheers

That is one interesting log being about 40" wide at the widest part - it's a red gum, however it's low on my milling priority at the moment - I have dozens of easier logs piled up in the yard here to tackle first. I was thinking of to cut it in half and then milling a couple of 36"+ wide slabs out of the wide part. Meanwhile it's not going anywhere.

Cheers

Procon Technologies have the same thing for $148.50 + $9.90 delivery
Or the EL-USB-3 (32k readings) plus better resolution etc for $176

nice addon for the highlift.

Just a comment on safety!!!! you should include a chain which could hold the log onto the adapter. You dont want a log falling on your foot from that height.

Thanks Arthur, I have no illusions about what damage even a half ton log can do - I spent too long as a kid around saw mills. The primary risk using the highlift is not the log slipping off the adapter but the whole thing tipping over sideways. To reduce this risk I will only be lifting the log about 60 mm at a time before slipping a 50 x 100 mm plank underneath. This way if the planks are long enough the most the log can tip is about 70 mm before it contacts a plank. Over the course of milling the log, I probably only lift it about every 2 or 3 slabs so that will be around 3 - 4 times per log.

I'm also thinking of adding a wider base and some side arms to the highlift (as per picture) so it can't easily tip. Might add some teeth to the adapter so that it grips the log better too.

Dingo I have used that idea for over 6 years now. Back in Adelaide and now here, 2 wirlygigs in the roof and mounted underneath a cheap bathroom air extrator.
Sometimes Ive gone into the double garage thats been shut up and even with wirlys its been stiffling switched the fans on and dropped the temp about 5-10 degrees.
Gets my vote

Sounds good, I am considering using something like these fans and have them connected up to two humidity sensors so they switch on when the humidity on the inside of the seatainer is greater than the outside.

Electus have a similar thing for $100 . . . . .see

Hi BobL
At the risk of being howled down I fear that the uncontrolled dehumidifiction of this seatainer is going to waste your wonderful stash of timber.
My understanding of controlled drying is to maintain a steady temperature whilst dehumidifing the surounding air at a controlled rate so as not to exceed the capacity of the timber to lose moisture without degrade (splitting).
My vision would be to insulate the container, have small fans inside for circulation, a humidifier for when the humidity drops too fast and fans in the bottom of the container to daily vent a small volume of air to the outside to gradully lose humidity.
I'll go and crawl back under my rock now
Sincerely BobT
