Episode 108 DadoStop!

Had a look at the blade(s) after the fact, and found out where the significant cascading sound comes from when the brake activates.  12 separate tungsten carbide teeth ripped loose of the blade.  Most presumably are due to the spacer blades not being in direct contact with the aluminium brake, so were able to move when the blade was (rapidly) decelerating, and knocked the teeth off as they slid past.

It is a good effort, stopping that much spinning steel on a dime!

Addition and Subtraction

The battlefield of the very near future could be quite a different place indeed.  At least as far as logistics and materiel supply is concerned.  I imagine it will be even more profound for the Navy, who have a stable working platform (stable by our standards!)

Where once, a battle was fought only as far as the supply chain could stretch, and every spare part imaginable was carried, it will soon get to a point that all that will be required is the generic raw material, and the ability to fabricate any required part in the field.

The age of one-off part creation is upon us.  It may still be in its infancy, but RP (rapid prototyping) and RM (rapid manufacture), in the form of 3D printing is about to become an unbelievable growth industry over the next 6-10 years.  Even the Formula 1 is taking it very seriously.  They already use 3D printing for prototyping parts for their vehicles, but it won’t take long before the cars themselves have 3D printed components on them, especially where it comes to recovering from an accident.  Cars are occasionally knocked out of the big event due to a crash during practice, and the inability to get the required spare.  This costs the team a fortune in lost exposure, lost advertising, let alone potentially lost championship points.

3D printing is a form of AM – additive manufacturing, where raw material is processed and added to build the required component, layer by layer.  This is no longer restricted to plastics either, with companies now able to utilise titanium 3D printers.  This results in products that goes far beyond prototyping and concept models, and results in fully functional products, some which cannot be made by any other method, with moveable components in seemingly impossible locations.  Impossible if traditional fabrication methods were used.

So where 3D printing is an additive manufacturing process, CNC routing is a subtractive process.  You start with a block of raw material, and carve away everything you don’t want.  Each have their advantages, and CNC machining has now been around for decades, so is a very mature process.

Soon, both additive and subtractive computer manufacturing in my workshop.  The Redback CNC will give me the subtractive process, (in spades), and a soon-to-arrive 3D printer will let me start to become familiar with additive manufacturing.  The rolls of filament arrived during the week, so hopefully the 3D printer is not too far behind!

Some news!

There will shortly be a new CNC machine (CNC router) on the market.  Once that is Australian designed, and made as well.

Comes from a pretty interesting stable too – the same inventor behind the Torque Workcentre, and his company, YAS Engineering.  Now Keith (for those that don’t know) is actually a specialist in CNC machines, and has been making custom builds for years from the small, to the very large.   This design is one for production, rather than custom builds, and it is only about 6 weeks or so away from making the transition from prototype, to the first production machine.

And that machine will be making its way down to sunny Melbourne, to a modest shed that I am somewhat familiar with!

The bed on the CNC is 600x900mm, although the overall cutting capacity of the machine is more than that (yes, more, not less).  That means it can work over the end of the bed, so working on the ends of boards etc will be possible.

Thinking Aspire would be the best product to get to really showcase the capabilities of the machine, rather than just sticking to VCarve.  Have played with VCarve already, looking to jump to the next dimension (the third dimension) with my CNC routing!

More news as it comes to hand!

 

Raising some revenue

I’ve had the tool section running for a little while now, and it has been good to (slowly) move on some items.  I’m going to keep the section running, as there are always a few odds and ends (spare components primarily) that can find another home.

I am looking to really ramp up the production quality of the videos again, and have new lights, new mics, and am now working on adding an extra camera as well. So I’ve turned (once again) to eBay to move a couple of things to assist.

One is the radial arm saw.  It may go for less than it was offered on here, maybe more (although I’d be surprised).  It is currently at $8, with 5 days to run, so is quite the bargain (if you want a radial arm saw that is!)

The other item currently listed (which has nothing to do with woodworking, but at least the revenue raised will!), is the last of my dive gear, which I used to do a lot of deep diving with.  Currently at $270, with 2 days to run.

Sad to see it go, but I’m not using it, and one past hobby can help fund a current one.

Episode 105 Freeform Router Bowl

Using the Amana Tool bowl bits from Toolstoday.com, I create a freeform double (interlocking) bowl

New Festool Product Demo

Headed along to Carbatec this morning to see the new Festool products that had launched. Unfortunately the edge bander was not on show- demo’ed at a recent session, but now saved until some show in Brisbane.

Saw the new cordless hammer drill, and yes, impressive if that is what you need. Lightweight, shock absorber built in etc.

Comes with a really neat dust collector.

It sucks itself onto the surface, and gathers dust right from where the drill bit is in contact with the wall (or whatever you are drilling). Also available as a separate item for about $35. Definitely have to get one of those!

Saw the new cordless saw in operation too. Brushless EC-TEC motor, takes either 1, or 2 batteries, and that can be a mix of 15V and 18V. Depending on the available voltage, the max speed varies from around 3500RPM to around 5000RPM

Without batteries fitted

20140728-135857-50337901.jpg

Dual batteries fitted, each with charge indicators.  The saw must have a battery in the lower slot to operate.  The second battery in the top position is optional.

Has a different handle, that prevents the saw being used on the CMS system.

New lever to allow saw to be tilted to -1º

Has a new design to the Fast Fix system, which allows the blade to be locked and lowered in a single operation for blade changes.

For a saw that can be used onsite, away from any available external power supply, I’m sure it will be of definite interest to many.  If you are in a shop-situation, you’d still stay with the TS55R (the corded version).  This one would be awesome to use with something like the Centipede Workbench to break down sheets before bringing them into the workshop.  No need to run cables etc outside!  Also if you were working in difficult-to-access locations (such as in a roof space), the portability would pay off well then too.

Saw with 1 battery attached.  Note, this was the first time the saw had been used with the rail, so you will see the sacrificial plastic of the rail peeling off as well.

Saw with 2 18V batteries attached.
