• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Chop saw dust extraction.

Hello Chaps,

I've been working on a dust extraction programme in my shop recently, with one objective - making improvements! Apart from the table saw, a few chop saws, a small band saw and a small pillar drill, my machines are power tools. I have now sorted out a good dust extraction for all the power tools (including the jigsaw - video on its way!), the table saw, the band saw and now the chop saw. 8-)

The chop saw is a tricky customer for dust extraction and so I've adopted a neat little idea to minimise the fine particles of dust flooding the workshop with nasty contamination. It's amazing how good this really is. :P

I've put together a short film.

The film's clearly a secret!

I set my SCMS up yesterday outdoors, and then the wind changed direction. I spent the evening in great discomfort, wishing for bedtime to arrive so that I could finally leave my eye shut to sort itself out. Sure enough, in the morning there was a great deal of crustiness around it, including presumably the offending piece of sawdust and my eye was pain-free again. So your solution is awaited with interest here.
 
Clever indeed, but I guess the balance between having enough suck to dump the dust at the bottom of the enclosure while not sucking too much up into the filter is critical.
 
What on earth are you people seeing? I've just got a blank white square.

Same here (Safari on a Mac)

Chaps

I'll say it again, the issue is with YOUR machines. Recently Google have effectively stopped supporting certain Flash completely now, as have many other browsers, and to defend against vulnerabilities such as Poodle, they have disabled support for TLS 1.0 and SSLv3 (internet comms/security protocols). If you are using a browser which still supports either of these things then you're going to have trouble because Google own YouTube and have turned off support for these protocols there too on their main sites (YouTube being one).

Google's approach is a little heavy handed because they're effectively telling people what they can and can't visit, but ultimately is done for the good of the wider community to help prevent a vulnerability from being exposed by those with nefarious intentions.

Simple fact is, TWH2 is working fine and as expected, if you want to be able to see YouTube videos that people post then you're going to have to use a different browser or take the latest upgrade for yours, assuming that is also secure enough for YouTube to allow you to see their content.

It works fine on tapatalk because that isn't limited by the deprecation of Flash support and thus isn't valid in the context of this conversation.

I have a Mac at home which is an old OS and as such in both Safari and Chrome I only see the white box as you do Mike, because I am on the latest supported version and they have ceased further development, so my only option is to upgrade my entire machine. On my work machine which is Windows 10 I can see the videos absolutely fine in both IE and Chrome, for the reasons mentioned above, they are current, supported and on the latest version.

If you want to be able to see all content on this site then sort your browser situation out as there's nothing I can do to fix it for you from this end.

Sorry if that sounds ranty but I'm getting a lot of negative vibes for the things that people can't see, and this one I need it to be understood is absolutely nothing to do TWH2 and I can do nothing to help, well nothing more than I have already.

Cheers
Mark
 
If anyone is seeing strange behaviour like this you tube problem then don't immediately comment about it in the thread but instead press the quote button on the offending message and look at the content. There you will see the underlying code including links. Simply cut and paste these into your browser or you tube viewer. It is not rocket science and it save pi88ing mark off by implying there is a forum problem.
Simples!!

Simmer, gents. No-one has implied that it is anything to do with the forum. I assumed that it was a simple balls-up by Paul. Turns out it isn't... The thing is, it's a different sort of non-show from those I've had before, with just a blank white square rather than the more typical little thumbnail/ icon thingy, so the immediate "it's my fault" reaction didn't apply.

Understood Mike, perhaps an overreaction on my part but I tried to explain it on the other thread last time and this is the same answer I'm afraid.

Google have been doing things over the past 2-3 weeks which has meant that my experience has gone from normal video view with a message below, to absolutely nothing showing, then to the white box you and I are seeing now, all differing symptoms of the same cause unfortunately.

Cheers
Mark
 
Thanks for the replies chaps. 8-)

Good point Andy... I'm going to gauge the filter at regular intervals and see how it's doing. I think it will only extract the very fine dust which is what I'm hoping to achieve. 8-)

It's a shame some of you guys can't watch the film, but following Mark's instructions will no doubt get you there.

I watched it on youtube. That set up looks like it would work OK, but it takes up too much space to be applicable in my workshop.

Just as an aside, Paul, to you have a special blade in that saw to prevent tear-out? Can you use stuff straight off the saw in furniture?

I always keep an eye bath to hand for just such a situation.

If you use a backing piece, Mike, then you shouldn't get any tear out. Or use a false fence that runs all the way along the back of the existing fence (well, front...but you know what I mean, I hope) and then make your cut. The saw will cut through the timber and also the false fence. That is also now your cut line and useful as a future aid but also the false fence should stop tear out.

I've probably explained this very badly...been a long day.

Re the Youtube viewing issue...I'm on Safari/Mavericks and also get the white square. Think I may have to bite the bullet and migrate to El Crappo. Last migration I kept Snow Leopard in a separate bootable partition as IIRC I had some software that wouldn't run on Mavericks (Adobe Creative Studio/Photoshop I think) but I rarely use any photo-editing stuff, never learnt Photoshop to do it justice and so have never booted once into Snow leopard. So this time I think I'll just bin it all (Mavericks and Snow Leopard) but just might take a spare bootable backup in case there is a Gotcha I haven't thought of.

Either that or buy a new Mac !!

Sorry, Pinch....bit of a thread jack there.


Brilliant solution BTW
 
Cheers Roger - no worries matey.

Glad you like Mike. It works really well and it hasn't cost me anything to make apart from my time. A big advantage I have with this set up is the deep revealed window.

I've just started a new thread focusing on power tool extraction.

Yeah, it's the faffing around with that when you've a production run of cuts that bugs me. I just wondered if anyone had used blades that did this job cleanly, without having to find endless pieces of scrap.

Sorry Mike, I forgot about that bit... I sometimes fit a finer tooth blade into the chop, but to be honest with you, the current blade works well with hardly any tear out. Operating the saw aggressively will produce tear out, so part of this is the feel for you tool and the piece you're cutting.

I don't understand 'find endless pieces of scrap'. I will use a strip of MDF fixed to the fence and will use that for months unless I start making angled cuts or mitres.
