« Part 8: If I had another hand. Part 9 of Stupid Ideas/Buys of the past (so far)... series Part 10: All in the numbers. »

Boys and Girls,

We all like to brag about our achievements and sweep our failures under the carpet… well, my carpet has run out of space so I’ve decided to group my failures and mistakes under Stupid Ideas/Buys of the past (so far)….

I use a lot of prefab’d plastic blast gates, that tend to get jammed after a few months of use to the point that they will not provide a sufficient seal.
Sample of gate(s) supposedly closed,

Indication of the gap due to blockage on one of those typical blast-gates,

Now extrapolate that ½ deczon (my metric equivalent of dozen) times and the overall suck sucks.

I got sick and tired of clearing them, especially those ones held in place by rolls of duct tape and decided to make some self-cleaning ones myself.
I won’t go into the where, how and what, and you know the why (above), I finished up with this little gem after inspiration from a couple of casks of vino,

using my laser cut, dowel aligned method, that I have used in many of my previous projects.
Connection idea (not implemented),

Actually this was a very recent venture… that’s why I went into my shell from embarrassment and have been keeping quiet for the last few days.

After moving to Churchill 10 years ago, I recently made a visit to Carba-Tec (one of the very few dedicated woodworking suppliers in Victoria) and discovered their self-cleaning blast gates made out of the same plastic material as my current self-blocking ones…,

Unquestionably without bias, I prefer my design (as that they had to change theirs due to my consideration of applying for a patent pending expression to protect my invention).

However, their plagiarised version did have a threaded inlet for flexi-hose and included mounting feet,
bloody posers!

Stupidity was not in buying a commercial version or designing my own… it was in me fabricating a commercial $14 item for roughly $80++ (that included hardware, PVC, use of laser, design time and labour) and never getting to use it and I still haven’t designed or costed the mechanism for satisfactorily connecting mine to 100mm outlets.

PS. Another item to be crossed of my pending projects to be posted list.

PPS. While I could probably write a 5 star review of the plastic offering, I just refuse to spruik my stupidity.

PPPS. And this idiot made 3 of them,

thereby, exacerbating the loss.

PPPPS. Sorry, big post… to compliment a big disappointment…

I have a few of those gates at the top of your post!

Cleaning is simple and easy, just grab your cleaning toolset (thin, long shaft screwdrivers, various bits of stiff coat-hanger wire, compressed air gun extension set, dental picks, and a “tapping” mallet) and have at it! rarely takes more than a minute or two (beyond the 1 hour mark)..

Rejoice in the money saved over a self cleaning unit by cleaning it yourself

8^)

Hey splinter’.. I have all the tools… many more than I can give away and even more than I need. I have tools under tools, tools over tools, tools next to tool, redundant tools, aluminium tools, plastic tools…. need I go on… even tools used by a tool... I even have a drafted missus armed with a with a Dyson lurking in the background… all to no avail!
Contrary to what pottzy calls my nasa laboratory, I don’t have that ray-gun that makes those tools pass through that bloody plastic from the outside without disamtming the machine… hmmm, maybe if I just removed the ducting would be easier.

Maybe what you don’t have is a laparoscope. Don your surgeons mask and drill a tiny hole near the duct/blastgate junction and have at it with a good rooting. You could go dumpster diving behind the local hospitals OR for an off-cast unit, complete with video feed and the assorted attachments to make it all worthwhile.
For me, the afore mentioned plastic creations of genius are just slip fit into SDR gauge PVC pipe, a perfect friction fit for easy removal of the gates.

A well trained sewer rat could also accomplish the task, just smear peanut butter on anything you plan to cut that makes dust, The PB will collect in the troublesome crannies giving the helper rodent a tasty target. (remove PB from projects before finishing with mineral sprits)

This post is titled “stupid ideas”....

Thanks for the suggestion, however, I’m worried about blast(ed)-gates and not blast(ed)-missing-fingers

Pesonally, not a good idea… then I’d have to invent a self-cleaning rat cage and I’ll bet there’s already a cheaper commercial one somewhere out there!

i agree about those plastic gates (top) that always get clogged,some more than others not sure why,so i have a little tiny screwdriver that i put a sharp point on and bent a 90degree angle on that works great for cleaning dust out of the tight grooves,still a pain though to have to stop and do it so ive switched most of mine over to the self cleaning ones (bottom) and not had that issue.i though about making my own but i dont have the high tech equipment of some i know here so i just bought em.im surprised ducks you dont have those high dollar automatic gates that turn on with the machine? or maybe you could hook em to something like alexa and just tell her to open them for you as you sit and drink vino while the machines are busy doing projects. 8<)

When I can get to it, I use an allen key... works like a charm… when I can get to it… bloody duck tape does slow me down a very, very huge tad! I don’t have to look far to find one… more allen keys from all my gadgets on my floor than sawdust…. did have a lot of issues initially, till I discovered holding the long end of the allen key worked better!

This time I’m way ahead of you pottzy... Tried that and it worked boo-tyf-li... for ON... but even screaming, I couldn’t be heard over the dusty’s noise, barking the OFF command…

PS. Still working on a ”Alexa… pour me a vino” command.

Don’t know about your SWMBO, but my missus hates being referred to as a robot... easy ladies… I’m just kidding… I pour her glass before mine!
