Shed.TV

It has been a long time coming (since October 2013) but I have finally finished the recataloguing of Shed.TV

Thought it would take a few weeks. 21 months was close……..

It was originally driven by the unexplained dropping of my channel from Blip.TV, so I started the process of transferring all the videos directly to the WordPress.com server.  About 16 GB of them (there are more now – another 60 since then – 7 more hours of footage).

After taking that step, I decided the indexing system needed a full revamp.  It was becoming very cumbersome and once we passed the 200 video mark, that is a lot of thumbnails that need to load.

I decided the thumbnails were not adding sufficient value to maintain them, so they were sacrificed.  The numbering system has been maintained, with two primary forms of videos.  The main episodes, which tend to be longer, are fully edited and have more effort put into them, such as multiple cameras, lighting sources etc, and shorter more basic versions, shot on one camera and uploaded directly, with little to no editing.

The first version are called episodes, and their numbering has an “ss” suffix (for Stu’s Shed). The second are the YouTube Chronicles, and have a “yt” suffix.  There is a new numbering system that has been introduced, which simply starts at 1, and continues incrementing, currently sitting at 212 videos in total. (32 hours total footage).  Around 30 GB worth.

So check it out at the tab at the top.  Hope the streamlined indexing meets with approval.

As to blip.tv, they are shutting down forever next month.

Waiting for WordPress to fix their screwup

If you wonder why the blog has suddenly lost the header image, and the wood textured background, seems that there has been a FUBAR in WordPress world.

Has apparently happened to 1000s of blogs all hosted on the WordPress site.

Great stuff – hope they repair it soon – not exactly enjoying the plain blue banner!

Goldilocks

Doing some further research into feed speeds, to see if I can do something about improving my router bit survivability.  Looking for the feed speed that isn’t too fast, or too slow.  I need the goldilocks solution.

Using a trial version of the G-Wizard from the CNC Cookbook, and it suggests (if I have entered all my variables correctly) that even at 10mm/sec, I was operating 5 times faster than what would be optimum.  It recommends 146.3 mm/min, where I was running at 600 mm/min.

If nothing else, it will be a good test of the software to see if it can lead to a more favourable (and successful) outcome.  Not exactly the cheapest software for what it does either – $US130 for 3 years (only).  I’ve only signed up for the free trial – paying for the temporary use of a product does not exactly inspire me.

Silver Sawdust

After conducting a successful test yesterday, I thought today’s effort would be a little more rewarding, but events proved otherwise.

After spending a good hour or so (felt like longer) getting set up with the cameras, lights, mics etc for the video, I starting recording, then starting the nesting operation on the CNC.

I was routing into 6mm thick aluminium, using a 1/8″ single flute upcut bit specifically for the job.  I was running at 10mm/sec, with a 1.2mm depth of cut.  Compressed air to clear the chips, and WD40 used generously for lubrication

The first piece cut cleanly, but only a few inches into the second piece and without warning the bit snapped.  By no warning, I mean that it didn’t sound like it was struggling, or vibrating, but snap it did.  It didn’t break near the cutter either, but about 1/2 way up the shaft.

So I thought I’d change to a 1/4″ cutter, cut all the pieces, then go back over with a 1/8″ cutter to refine each piece, and cut the required slots and mortices to join it all up/

This did not go well.  I needed to have completely changed the layout for this to work, and the tabs.  What happened was the sheet’s structural integrity became compromised more and more as the pieces were cut, to the point that they would break free from the sheet.

By the end, the cutter was blunt, the sheet had suffered from so much lateral load that it had begun ripping the screws out that I used to hold the sheet down, and pieces were coming loose left and right.  And there was no chance to refine the pieces to their final dimensions.  The pieces look good, but at this stage they are unusable without a lot more work.  Back to the drawing board.

Al-1Hope these pieces don’t go to waste – took about 4 hours of machining to get to this point.

Test Cut

In preparation for an interesting job tomorrow, routing 6mm thick aluminium for a nesting operation, I made a quick test piece today.

It was made in 3mm thick aluminium, but would be a good example of what I would be expecting to happen.  

Depth of cut of about 1.2mm, and started at 20mm/sec feed rate. Decided after a few secs to drop that back 50% to 10mm/sec. That seemed a more appropriate speed, and more in keeping with what I saw at a shed visit a few days ago. (More on that later)

Using a generous amount of WD40 to lubricate and cool the cutter, and regular blasts with compressed air to clear away chips to help prevent clogging of the flutes.

  

STUSSHED at GSMEE

Stuart of stusshed.com gave a most interesting talk at last nights GSMEE meeting.

GSMEE, in case you are not familiar, stands for Geelong Society of Model and Experimental Engineers.  A select group of people who are interested in things mechanical, electrical, steam, internal combustion, boats, etc.   Mainly metal working, but sometimes involving woodworking.

Stuart generously gave his time, and drove several hours to show us some of his projects, and tools which were new and unusual to most of us.

He explained how when he was a very small boy, an uncle disappeared into his workshop, and a short time later reappeared with a simple wooden puppet toy which he had quickly made, and presented to Stuart.  Stuart says that event made a lasting impression, and was influential in his decision to make things for himself, have his own workshop, and eventually to study mechanical engineering and have a…

Xmas in July part 2

While it may be a bit too organised to be preparing for Christmas, it has a horrid trick of creeping up on you, so some early prep is not a bad thing.

MakeCNC.com have a range of models suitable for a number of holidays, and of course Christmas is no exception.

While there are a number of models in their range, I found enough time to make these.

The first is Santa’s Workshop, which is rather impressive.

   
    
   
There are some superb features- a workbench with items in progress, overhead hooks carrying items around the workshop, items stored around the walls, including up high with ladder access and a full fireplace.

All run by Santa and 5 elves.

The second model I made is Rudolph, which is a neat little model, and has 2 sets of legs- one set for standing, one more ‘action’ oriented.

  
I made a couple, one in 12mm MDF, and one in 3mm which is particularly cute.

The final one I’ve assembled is an awesome snowman (and if you have young girls, you’ll find yourself humming a certain song. If you don’t know what I am referring to, count yourself lucky!)

   
 It is very clever, from top hat to carrot nose.  I can well imagine mounting a light (electronic candle) in it and having it as a lantern.

Other designs include a full nativity scene, Santa’s sleigh and a Christmas tree with ornaments. 

With a little added colour, these designs will really pop.

If not for Xmas in July, you can get a head start on December, along with Halloween & Easter.

As always, you are not limited to MDF (acrylic snowman would look great), nor do you need a CNC router.  The plans can be used for scrollsaw, bandsaw, laser etc.
