hahaha so did my other argon (the laserphysics). Almost felt as though after the first run, each time I spooled it up, I'd first have to call ground on 124.25 to get permission to start. They do indeed sound like a jet winding up :) Also those grills are on them for a reason - you'd know about it if you accidentally put your finger in one. Probably take it right off!

My LP WC300 fan scares my wife and cats. lol
takes a good 2-4 sec to spool up and almost sounds like it wants to suck itself inside out! good thing it has a full metal cowl.
i have been considering a boxed in, quieter remote fan but not worrying about that until i can find a suitable, more permanent location for it.... right now it's just sitting on a barstool in the corner, looking at me, judging me for not running her more often.......

do you guys mount you ARs or leave them loose and movable?

Thankfully I've never caught my finger on the fan for an Argon, although I have done it with the fans inside of servers, those aren't a lot of fun either. :D

Need to run mine more often too...

Just have my unit sitting on top of the glass shelf on my desk (I have an old reception desk at home). Convenient spot for it, right near one of the outlets in the kitchen and I can fire it up right there without having to move anything.

My previous ILT (now living up north) sat under my workbench. Out of the way, but close enough to a kitchen outlet to allow me to do a monthly burn. If I wanted to bring it out for display, the coffee table was the place of choice (seen in the film where I unbox the omni). There it has all the 240V it needs - thanks to the 2700V/A inverter seen in the background (thing with the green lights on it). Thats powered by 16:wtf: 12 volt batteries, and could run an argon for up to a day. Or keep my loungeroom powered for 2 days. Yes I have tested the setup. :p

My battery bank is rated in the 10's of kilowatt hours. I have easily managed (as I said) to run an argon off it, as well as my computer server, desktop, surround sound, big screen tv... the list goes on. Sitting in the hallway soon to go outside is 2kW of solar panels. Once they're up I *should* be able to simply flick off the mains, and run totally independently from the power company :p

edit: Well folks, I finally tore down the omnichrome. I decided to toss the frame bagged with the tube still inside to prevent a BeO risk. Even put the top cover back on. It'll be picked up on friday for proper disposal.

I ended up with a nice collection of optics (more than I expected), the start board and power sensor, two massive jet engine fans (one will go on my ILT), a pair of thermal trip switches and the socket from the side panel where the umbilical connects. This means later on I can build an ion power supply and it'll look good with the proper connector. I carefully cut the cables inside the head at the parts end to salvage the connector.

I tossed the frame, top cover, fan shroud, hobbs hour meter, tube (still in the frame) and the banana jacks.

It was quite an interesting experience. I also found one of the brewsters were broken (not due to my handling) when I removed the optics holders with the brewster covers still attached. I removed these like removing the trigger from a nuke, slowly, carefully so as not to bust the optic. So it must have had one hell of a shock in transit in its p!ss poor packaging.

The ILT I ordered has just arrived at Enlarger in KY - the GSP processing place for e-bay. I hope Pitney Bowes doesn't "f" with the packaging, as it'll be on their heads if they do and it arrives broken.
