Newbie from Sweden

Hello everone I´m Andi from Sweden.

I have a question about drilling the laminar hole in the plexiglass, I have tried to drill the holes but the plexiglass is cracking what shall I do ?


Best wishes Andi

I can also mention that I working with 4 mm plexiglass, maybe I have make a misstake about the laminar hole? I drilled 16 mm hole and my brass nozzle has 11 mm in the nozzle.

I need some help please

Andi

I have solved the problem

Glad to see you solved your issue! What did you end up doing to solve it?

Hi guitar man...it's just funny but your username tells me that you're a musician like I'am (laugh)

OK I did some plexi bonding around the nozzle with lot's of grinding, alot of sweat and tears lol

my nozzle it's made of brass from a water hose connector, I cut it and did some more grinding and finally polished it up with some fine steal wool #0000

My first attempt to see the water stream looks like this :-) http://m.youtube.com/watch?feature=plcp&v=sKMw0beGmW4

Very cool! I wouldn't call myself a "musician" but I do like to make noise with my guitar!! LOL

Your first attempt looks very good! Nicely done!! Is that a leak I see in the video near the inlet of the jet? If so, sealing that up would definitely make your stream even better!

Would be interested to see how you made your brass nozzle as I am struggling to make a one, do you have any pictures of the brass bit?

Thanks

Helly guys.

I recommend to NOT use plexi, but instead use lexan !
Lexan is stronger and can be cut, drilled and bend.


I use lexan on my laminar nozzles

Hi Liteglow,

I made my nozzles from 304 stainless steel. I had some navy brass but was told it would get pitted overtime. There are drill bits that are designed for drilling plexiglas. They are ground differently, you can use WD-40 or kerosene as a lubricant. Don't let the drill bit get too hot, clear the chips away often. If the Plexiglas get too hot it will develop stress cracks. I designed a fountain for my Science Museum with four laminar flow stations. I'm using pneumatic cylinders for my cutters. The cutters are programmed but can be operated by push buttons aswell. The elector magnetic cylinders were too dangerous @ 1 amp.
