I dont like flocked brushes myself, but to convert it remove some of the bristles for jet holes or se the jets over the top either glued to the stock or through, Luke

flocked brushes catch dirt and keep it, therefore causing spotting, Luke

Here are some photos of a Bentley brush I converted.

The holes are 6 mm. This gives a nice tight fit to the pencil jets. Because the brush back is so much thinner than a Vikan, the jets stick out. I never found this to be a problem as they never touched the glass.

You have to remove bristles, of course.  I think I probably removed too many. There was no need to remove the strip in the centre. It's only necessary to remove those immediately surrounding the jet.

You can use one of the holes left by the bristles as a pilot hole to drill the 6 mm hole.

Yes, it worked fine. I didn't find any problems with it being flocked.

Many people say that flocked brushes hold dirt whereas monofilament brushes don't. Just because people say it, doesn't mean that it's true. It doesn't mean that it's untrue either! Plenty of people use both flocked and monofilament and get perfect results. I think it comes down to technique and knowing your brush.

The main advantage is, of course, that it's soooooo light compared to the Vikan. It really does make a difference when reaching at an angle to get to awkward windows over conservatories etc.

The disadvantage I found is that it's poor quality compared to the Vikan and doesn't last as long. But at cost of less than a fiver, who cares?

If you use Gardiners jets you will need a 4.8mm hole drilled for them i believe.
Title: Re: bently brush

4.8 mm diameter, hey? OK, advice is: (i) to measure your jets before drilling any holes and (ii) don't take advice from twits like me as gospel.

And another point worth making is that there is no law which says that the jets have to be on the centre line of the brush.  There is no reason why they should not be in the top row of bristles or even mounted on the top edge of the brush.

And with the low cost of the brush, you can experiment and find what you like best and what suits the way you work.

And there's no law that says that jets  have to be of a given length either, I make jets that are only 5mm long.
I use Algarde aquarium hose for jetting up brushes, and brass wood screws for making the jets.
Drill a hole slightly bigger than the hose diameter half way through the brush, drill a hole the same diameter as the hose the rest of the way through.
Push the hose through the brush, stick your jet into the end of it, and pull the hose back up so that the jet is wedged in the hole. It's as simple as that.
The hose won't pull off the jet either, like it does sometimes when you catch the hose round a patio door handle.

Trying to drill 2mm holes through a 1 inch length of brass was a pain, even on the lathe, drilling a hole through 5mm is a piece of cake

Wally I would stake my life on this being fact. They just do. In my opinion there is no argument, Luke

I gave myself a get out clause there intentionally. I was a little suspicious about this and open to persuasion.

But if you are that confident, Luke, I happily bow to your greater knowledge. You have persuaded me.

greater knowledge, I doubt that. I just know it as fact from using flocked Vikans, Bentleys etc etc and mono Vikans, Ionics, Tuckers etc etc. Oh and the Tucker brush is just fantastic, its a real time saver, just a brilliant brush, Luke

luke dose this happen if you rinse on or off i always rinse off unless high then i semi rinse on and off with one edge of the brush off the glass going down the glass

Flocked are especially bad for rinsing on, and I dont believe its even an option with a flocked myself. Luke

Yet I do it all the time with excellent results. A lot of it is down to where you place the jets.
I place mine one row of bristles down from the top, so there is only one row of bristles that could leave any debris, and that row is washed constantly.
Think about it, if you were using jets mounted over the top of the brush, the last thing that touches the glass would still be water. Your brush is underneath so it's the same as rinsing off.

MBS I have posted a picture on the ground floor pole for domestics thread.

You will notice that this brush does not have jets in the middle of the bristles, the jets are nearer the top.
If you turned the brush over you would see that I have put the jets in the same row as the second row of bristles from the top.
I will post more pics when I next jet some brushes. Dai

no probs thank if you put them in the same row on the bottom of the brush so you put four jets in two top two bottom will this  be a lot better as in theory would you not be bruhing over clean water which is coming out of the bottom jets :-\

Here are a couple of pictures of high-set jets. One of them is detail taken from Dai's picture (I hope that's OK with you, Dai) and the other one shows my Addis brush that had such jets in.

thanks wally what do you think about putting jets in the bottom as well as said on my last post

Now having jets high - I can say that it seems to be of some use. I did it and liked the results, even with a crappy brush.

High and low? I really couldn't say. I'm not experienced enough to give a practical answer. Haven't done it so I can't say for sure.

The problem is that window washing isn't an exact science. It's not possible to say, for instance that rinsing efficiency is proportional to water speed hitting the glass or some such thing. If it was, you could set up an equation and solve it for a given jet type or configuration.

Because of this, you can only really go on anecdotal evidence (like Luke's) or gut feeling.

My gut feeling is that it would use more water to little or no benefit. I've run this through the mental maths computer and the numbers really don't look encouraging.

I have tried top and bottom jets, they are handy if you want to turn the brush upside down for doing the bottoms of patio windows and glass that is below you. Also handy for doing inset narrow slit glass in bays windows when you use the brush vertically the jets clean both vertical frame edges. I have 6 jets on my current brush to enable me to do this.

That's a lot of jets!!! And it's interesting.

What diameter are they?

Are they all on at once or are they selectable?

Dont know the size but are probably a tad less than 1mm - Hozelock green ones, they come in diff sizes just to complicate things. Put whatever size ones in you need. The more jets the more water you need and less pressure so if you tilt the brush with the wrong set up you can find all the water coming out the lower jets and none out of the higher ones.
They have a fine accurate pencil jet, the internal has a vortex chamber to enable this.
