Druidic Dabblings and General Twaddle !!

[V8Druid]

guess what I've been doing today ??

found a 2m x 1m in the pile ... ideal

the noble art of 'nesting' .... used to do a lot of that!!

four down - several more to go

a little 'attention' required

light lunch ..... coffee and Pam's GF Cappuccino cake .... yum

16 out of 0.55M sq

Seen that advertised, but no idea how it worked until watching this video. Very impressive. Would save a lot of people nasty injuries, but I don't know how many people will invest in it and whether it can be retrofitted to any table saw.

Yeh very clever, think I’m more impressive for that I got the link to work, there’s some very impressive stuff out there when you start looking.....think it’ll start to become standard as time goes on, just moving with the times and all that.

Hmm ..... not gonna do yer saw much good if that occurs on a regular basis ..... so sausages have an electrical charge ???? I presume that the saw in use was a purpose designed saw for this application. My big radial drill had similar sort of protection to save you if you got caught up in it ..... DC injection into the motor, stopped it dead .. called Instabrake or Spincheck (two main manufacturers) why not do the same, rather than have a destructive element in the system?
with Instabrake, you simply reset the system and carried on ..... never needed it, but checked it regularly .... fk knows what it did to the gearboxes in the old girl though

That saw has been around for 10+ years but dont even know if its commercially available
And i think from memory its the fact the sausage is touching the person and it grounds out through you activating the mechanism

I'd guessed as much Smiffy .... was being a bit flippant/humorous ....
still think that a DC current injection into the motor'd be a far better solution, than ramming the saw blade into an ali block though, with an identical effect ..... instant 'Spincheck' and could be triggered by the same circuitry that activates the spring loaded unit ... maybe even quicker, as there is no mechanical element involved (the spring and mechanism)and locks the motor absolutely solid

I've had this kind of injury with tip of my finger. Trying to do something stupid. Not as stupid as just outright feeding finger into saw but I still wasn't respecting it like I should. At the end of the day got a tiny bit smaller finger now but lot more respect. Anyway moral of the story I wouldn't have one of these fitted to machine. Your fingers shouldn't be anywhere near it!

Agreed ....
there are instances when 'Spincheck' is required ... radial arm/big drills, being one, where one occasionally has to be in proximity to the tool in use, or the swarf produced poses a risk, ..... but saws need ultimate respect levels, not summat that might just save yer digits, if you're stupid, or careless enough to put them in harm's way

I can think of a few instances when a DC injection brake would have saved someone's life .... couple of incidents in a big eng. firm locally where people have died, from getting wrapped up in a radial and i've some horrific pix of a big lathe incident, where a DC brake, stopping the m/c dead, would have saved the guy from a horrendous end

Instabrake/spincheck is now a legal requirement on radials .... should be on other things too

I thunk some tools should have brake bands fitted if they can stop a chainsaw they could work on a whole host of other things even hand held tools

It’s like anything with an element of danger, if you don’t respect it, then it’s gonna bite! Some things need incredible respect, and occasionaly being bossed at the same time, to stop the ‘bite’. You need confidence and a sharp sense of when things are going Pete tong!
Accidents usually occur when people are complacent and have no awareness of the dangers. Anyone who fires up a big circular bench saw and doesn’t automatically clench their fists a bit to keep digits out of harms way, just from looking at the fecking thing spinning! Is probably not giving it enough respect! I use an old saw regularly, must be from the 50’s, it’s a beast of a thing, obviously being of that era, it’s not fitted with the latest safety gadgets! But as soon as you flick that switch, senses are heightened! No getting away from it, it’s gonna hurt if your not on your game!

Proper training and making people aware of the dangers are very important. I’ve still not forgotten the safety videos we watched at school in CDT class! And I was 11 at the time! Certainly made you think, even at that age! I wonder if these things are still taught in school today? Or are we educating a generation of people who think that things will simply be made safe, without them needing to worry ?

Bloody spot on James .... great post

Are we actually "educating" 'em at all ... ???

Who knows?....I’m just glad I’ve got the opportunity to educate my two, if they are interested in the making and doing of things, which they are currently, then they will get as much education as they like

Aye .... most parents i know want their children to be able to earn a living as easily as possible, understandably ..... but there are limits on that one .... no free lunches in this world.
Being able to give them a set of skills, which're transferable any where is, IMHDO, a great education .... may never get rich doing it, but can always earn a living and as said earlier .... there will come a time when they will command far more respect (and income) with their skills There is a LOT to be said for having abilities and the capacity for self sufficiency, in as much as possible. ..... an 'ology degree' only puts food on the table, as long as there is a need for 'ologists' .........

modern VFD speed control drives usually have the capability for motor braking similar to dc injection brakes. I've got a VFD on a machine I'm building for the workshop and although it only turns slow, it takes a while to ramp down so I shall certainly be utilising it.

yes, IIRC, Variable Frequency Drives also have the ability to inject a DC dead stop current too, don't they?
That belt grinder I bought a few months ago has the braking system built into it .... me older ones in work used to take forever to spin down

Be Carefull with the bloody things, Guy down the road was killed by one, it chucked a pieace of wood straight through his throat.!!!!

aye ....... dangerous bloody things, circulars, especially big muthas.
used to have one that I made up from an old lead saw ..... 30" TCT blade, 9mm thick ..... direct drive on a 20hp motor .... was unstoppable and took maybe 15 minutes to run down ...... cut sleepers like they were balsa ... used to use it for cutting cribbing for the cranes, from sleepers ...... was SOME saw and got treated with the utmost of respect

 

[Jimoz]

You think a saw like that could be stopped dead with a device like in that video?!

 

[V8Druid]

it'd chop it into bits ... end of ...... DC injection'd be the only way to stop that ol' girl ..... the kinetic energy in the blade and motor was immense .... it'd cut a sleeper in half on the run down and still be going
