The living hell of dust extraction diameters

How to tell a PET bottle from a .... bottle?

The video does not state what bottles to use, it is in the comments, so I added the information.

Type “how to tell if a bottle is pet” in to google and you get “How can I distinguish PET bottles and containers from other plastics? PET containers are typically molded on the bottom or side with the number 1 surrounded by the triangular "chasing arrows" symbol and the acronym PET or PETE below the triangle. Only PETcarries the #1 identification code.”

I have just checked some bottles and the small lucozade are pet. It has a lower melting point than hdpe apparently.

No need to struggle with those. There are varying sizes priced between 5 and 10 quid. Blastgates arent expensive things.

Even cheaper when you make them yourself from off cuts and are self cleaning, the dust get stuck in them plastic gates not allowing to close properly.

I found this video, uses pet bottles and shrinks them with a hot air gun. Even made one for an oval dust port. Looks quick and easy, not tried it yet bit it looks good

I gave this a quick try and it worked. Here is a photo

That may work , but so......FUGLY!

As I said, it was a quick test to see if it works, the ones in the video look much better. Here is another Photo with the wrap removed.

Word of warning, if using plastic fittings try to get a close fit with the pet bottle before heating to minimise amount of shrinkage and heat required, and take care not to melt in the plastic fitting. Guess how I found that out?

That's much nicer, thanks! Oh dear about your little 'learning incident'.

I have in the past responded to threads like this with an easy solution but with no response.
My solution to this problem is explained in the following thread.
Take it or leave it as you wish but I don't have the problem that many of you seem to have.

If you can find someone with a 3D printer then you can design a custom adapter by going to this link:

And hitting the 'open in customizer' link on the right

or even better, download the files and run customizer on your own PC

Here is one I did earlier:

That is a good solution. It looks like you have used the solvent weld type connector and pipe, obviously without the solvent. I would imagine the two gaiters give a lot of flexibility to easily move the tool around. Also connections and disconnections are really simple, quick and easy.
