jin,
okay, let me take this a little at a time
I bought the table for $650 cash, which I feel I slightly over paid for but no one else in my area has sold a coin-op version for a long while...so he sort of had me over a barrel.
$650 is a very good price for a used Grey Marble...I think they are worth $700-$750 depending on condition
you have mentioned a bunch of things and makes me wonder what kind of condition your table is really in...if it has rusted rods, that is a bad sign...Grey Marbles made from 2003-2007 so even the oldest is not old for a Tornado...you can tell the 2003 units they were the 30th Anniversary model and on the table surface, below the logo, it says 'Product of Valley'...no table made after this has this phrase
back to the condition...you need to take a bunch of close up digital pictures of all around the playing field, all the bearings and rods and then I can help you better determine what to do
if it has rusty rods after just a couple of years, the table has been near a ton of moisture...most of the Gry Mrbls had the heat-treated rods, again, even harder to make rust...so, lets take a good look before you start buying tons of stuff
To give you some more history, I am the original owner of a MINT condition HM 2000 that I bought new back in 1994. Actually my buddy and I each bought (and still own) the grey marble version...at the time I think it was the only home version table that Tornado sold that supposedly played just like the coin-op version or something...but what was annoying about it was that you had to retrieve the ball from the goal, and if you had another ball in there and scored they would occassionally fly out.
I didn't know Tornado made a grey version in 1994...if you have to retreive balls from the ends, it doesn't play like a coin op....
Anyways, fast forward 13 years later and I stumble into a local pool hall and see a crowded Tornado table...with the likes of Terry Moore and other amazing local foos players. Didn't even know Chicago had a foos scene worth mentioning...now 2 years later I stumble upon this Tornado coin-op and wish to refurbish it.
cool story, so you are in Chicago land area? I grew up in the NW suburbs of Chicago - Schaumburg/Hoffman
I'd be willing to spend $300 or so to get it back to mint condition. In all honesty I can probably just swap all the parts off of my mint HM 2000 and put it on my brand old coin-op, right? Unless the rod and bearing designs have changed?
no on the swaping...don't know what will or won't match but if you are willing to spend money, no need to take 15 year old parts, even if they are "mint" to fix a 4 year old table
If they have changed the design of the men I'd like to change to the new style, and the new synthetic handles sound interesting... Without a doubt I'll buy the new balls, not sure what the 5 hour tumble thing is all about but I guess I'll be buying those.
talk to someone before you buy the handles to make sure you get the newest ones, there have been quite a few...talk to Jim Waterman who runs this board and the foosball.com retail site or Charles McIntosh (tornadofoosball.com) either can help you...I always try and give Jim my business first since he his helping us talk even now with this board...I mean, you wouldn't be asking and I wouldn't be helping if it wasn't for him
5 hour tumble means how long they put the balls in a tumbler to get the roughed up surface...for this ball, it needs this long to get the right nap that will stay for any length of time
the men - well, this is the most expensive part outside of new rods at 32.5 a rod...the men are nice to have but for sure not need to have...rods are a must have...hopefully you don't have a lot of those to replace because a whole set would be $260 which wouldn't leave you much for anything else
I have a few other questions... What is the best lube to use for the hinges and the coin-op mechanism?
I am not certain, 5 in 1 would be fine...others may jump in and give you another idea but I have know people to use a little silicone but I wouldn't
Also, how do you put the coin-op to "free-play"?
http://www.foosball.com/forum/index.php?topic=2708.0What is a good way to get all the goo residue off the metal parts of the back goal area? Also a nice stain from what appears to be a spilled beer into one of goals that got on the mdf...probably typical of a any bar foosball table.
do you mean the curved metal piece at the back of the goal? Hot water and soap, rubbing alchol, 401...just make sure you dry off any metal surfaces real good to avoid rusting

your table may not need new bearings unless you have to replace a bunch of bumpers...you may want to try and see if the ball fits behind the men...then if you find they do and you want to replace the split bearings, only plan to replace the 3 and 5 man rods
see my notes from the posts on
http://www.foosball.com/forum/index.php?topic=2704.0 on cleaning your new used table...it will take some work up front but once you have it all done, it requires very little maintenance each year...I put in less than 2 hours a year cleaning and replacing parts
