my diy needle wheel dart pump

all I can say is wow.... I am not sure if you are looking at the same pics as I am but bubble dispersion does not seem to be an issue.... I may have some bias because I have seen it in person, but looking in the pics, I think it gives a fairly good idea of what you see in person. The bubble denisty is thick straight through the body and is in nice milky alsmost smoke like consistency until it reaches the cone where the bubbles start to combine due to the transition from the body to the cone.... not because of the hex shape but because of the large lip under the cone that the bubbles crash into before rising up the cone.
anyway Scott (Spazz) & Stan it looks like all is better than can be expected for the intial test run. Stan what are we gonna do with this guy being so hard on himself
I think it is kickin some serious arse... However it can only get better with a round body, larger riser, and larger cone. Not to mention I can see the concept be hind the "S" curve and can definately see the possible advantages of it. The only problem is how to build it... anyone have any bright ideas to get Scott's little hamster wheel turning in the ol' noggin??? hehehe.... Of course he may already be banging his head on the router table in the garge trying to come up with a way to do it. :lol: I would also second the fact that a second pump would simply be too much since the bubble density is already so thick.
I guess in the long run I think it will do great but of course the proof is in the pudding and with the skimmate being the pudding... by my calculations that should equate to about 2,790 cups of pudding in 30 days.... that my friends is large batch of PUDDING

so lets see some pics of the skimmate it is producing and of it in action!?!?

that person (i am leaving nameless for now) has been so bussy he has not been able to send me his impellor and housing so i can make sure the new needle wheel will fit properly. i will be getting that impellor built in the next couple of weeks and sent to him. then he will have to convert his skimmer over to fit the new dart needle wheel.

i know there are alot of people who are wondering what happened to the sequence fourm and there advertising here on r/c.
i had to order some seals for my dart pump. i broke one of them messing around with the needle wheel. so i asked them a few questions.
the baldor motors are no longer available on any sequence pump. this is not by sequences choice. baldor quit making that motor. so sequence had to go to the al smith motor that you see on the new darts.
i asked them about the sequence fourm. they said they will be back some time in march. they got so bussy they didnt have the staff to keep up on the thread properly. but they will be back.
i ordered 2 sets of seals for the darts i have. there a little expensive but the lady was great to work with she even gave me a little discount because i was ordering 2 sets of them. once again sequence has A#1 customer service.

Agreed. Sequence rocks. Super pumps and unbelievable customer service.

I also am looking into it. Everything I have found is pointing to 3 axis machine. I have found countless examples of 3 d routing with a 3 axis. And these are home built hobby machines.
Try looking at cnczone.com

the problem with those hobby machines is they are not built with very strong main frames and the rods can give when under pressure from strong routing. im looking into a light industral model thathas a liquid cooled head and heavy duty ways that wont flex like the shopbots or other hobby cnc will. i had a demenstration of a machine thats pretty impressive for its size. its small 2ftx3ft cutting area but its very heavy duty for its size. it will even cut the ramps on the twist locks. i made sure he could deminstrate that. it will make flawless ramps with little effort at all. the biggest thing is the programs. they cost a fortune. and some of them like auto cad have a hard learning curve. the guy that did the deminstration has a degree in cnc machining and he has problems with auto cad. i like solid works but that program is a ton of money.
A good CNC software package is often as expensive as a single high end machine.
I'm using Catia now (Solidworks' big brother.), we get a discount of about 75-80% at the university, but I think it's about $100k per license otherwise.
I say this just to give you an idea, that $3k for a solidworks license, may not be that bad. However, Solidworks does not do the CAM side of things, so it wouldnt be completely sufficient for your purposes.
Pro/E does CAM I believe; I think a cheaper alternative is MasterCAM, but I have never used it. There are many many...
FWIW: I think AutoCAD is a lousy tool... decent for the money maybe, but there are far superior packages out there for equal or less $$.
There are free tools out there as well for linux as well.

I built a cnc router myself , Its not hard to do as long as you have the tools . Mine is welded and machined . I too looked at the shop bots an dthe ones made of aluminum extrusions and fond th eflexed too much .
I use mine mainly for working aluminim and its way overkill for acrylic .
It cost me around 5k to build . If you ave the skills to tig weld and have some basic machine tool you could build one also . I made mine with a 4ft x4ft bed so i could make flanges for big skimmers . I had ahell of a time with auto cad . so I have my 15 year old neibohor do the auto cad for me then I just clean it up in the gcode editor . I fond it a must to have a nozzle to blow the chips away while yourcutting .
