DIY audio: what are you building?

Trust me - it will be the best $50 you will ever spend for making boxes.

Beautiful clean holes that are a breeze to cut, and after you have finished 50 holes - it will be ready for the next 50 and 50 after that.  No BS, it will take you 6-10 times longer to make crappy holes with normal bimetal holesaws!

Likewise, do you have a link for me please? Don't care which store sells it, so long as I can get it online, Bunnings, H&F etc.

I have a lot of holes to cut in the upcoming projects, so this sounds like a great idea. Unfortunately, I can't find them on Bunnings website. Got a link?

 

I couldn't find them in the Bunnings catalogue either - hence I took a pic of mine.

 

I have seen them - they do sell them and mine fits a standard Sutton bimetal holesaw cutter arbor.

 

Those TCT ones are OK, but being a tradie I like the extra depth and ruggedness of the one I bought and that is what I would recommend.  I have tortured this poor thing and it just keeps going.

 

Mine  is caller a "RIPPER" and is made by BANDO.  Sutton make something very similiar.

Hope that helps.

Thanks as well. As these will only be used for MDF and ply, do I really need to spend the extra? Typically that will only be 1 thickness of 19mm at a time.

I have not used the TCT ones - so I cannot help you here.

Anyway, I do appreciate everyone’s input and advice. I feel like I might be hijacking this thread with stupid questions.

I think this thread is exactly the right place.  None of us knows everything and if we share here, we can all learn from each other.

 

Your gaps - I'd go a tube of Sikaflex polyurathane.  Don't go to the normal section of Bunnings for it though.  Got to the tiling section and get a tube much cheaper there.  Easy to apply/clean off, (push firmly into gaps) strong as and slightly flexible.

PVA glue and sawdust makes a great gap filler.

 This is the sort of thing I mean. Most are less than a mm. The PVA and sawdust thing might work. I’ve still got a bag full of the stuff that hasn’t gone to the bin yet. Next time I’ll just get them professionally cut but for now I’m deep in the warm embrace of the sunk cost fallacy

I was going to suggest Araldite but I just had a look at what it costs now for some stupid little tubes.

I can remember when my father use to buy that stuff in the tins.

With minor gaps that size just use AV glue and be done with, it won't fall apart or vibrate.

If that is too expensive or too hard to get hold of just use liquid nails or some other expandable glue.

Alternatively you could read up on all types of glue and then decide what is best for you and your budget... perhaps.

audiovisual glue, of course  ;)

 

 

gorilla glue is relatively cheap, but it expands quite impressively as it goes off, so small amount only required

Save me from explaining what can be looked up on the web and just Google "AV Glue" perhaps and you will find some links such as this one.

Thanks, that looks like just the stuff. Just a heads up, Sydney tools has it for $15 if you have one nearby

...So the same as Sikaflex polyurethane.

 

I've been around a long time and have never heard of "AV glue" before either.

If you add talc to PVA it will fill those gaps no problem. (just a little)

Check the Trojan website for details.

that stuff should probably be recognised as carcinogenic these days - it often has asbestos impurity from the mining sources (long story, but google johnson & johnson + talc)

 

you can but "microballoons" from surfboard makers (air filled tiny glass beads), but sawdust is the most sensible and obvious thing to add to glue - balsa dust works fine too - it's a hardwood

I’ve posted this on the Pi Moode thread. Upgraded to Pi4 4GB but they run hot. Also enclosure and PS are different. Using Moode 6.4 now, very good. Enclosure drilled and HS added to try to keep it cooler.

Notice any audible difference with the 4? I had a HS on my 3B but it doesn’t fit anymore after adding the Allo Boss. Haven’t noticed any difference on mine but I read the 4s run hotter

If they sound better it’s only marginal.

I couldn’t live with the horrible hardware job I did fixing my brain fart on the braces so last night I took them off and fixed it properly with dowels. It’s not perfect but when it’s bogged up and sprayed matt black and sealed away in the dark in a box for all eternity, no one will know. Also my cheap and cheerful 100mm hole saw arrived today so I should see some real progress in the next week or so, time permitting

Does it run cooler with the HS fitted but not enclosed?

I ask, coz enclosure looks too not-ventilative.

I think I just mad a new word :)

They still run hot out of the case but for now it hasn’t shutdown so must be ok as in the pics above.
