bought a 14" saw - think i over paid
So up until now i've had a tiny 150mm GMC hobby band saw thing which rarely gets used for anything. I don't really do alot that requires a band saw but every now and then i think it would be handy to have one. I bought the GMC thing 2nd hand off gumtree at some point.
Browsing through facebook I spotted a 14" 1Kw TTI band saw for sale for $350. Haggled him down to $300 and went any collected it. After getting it home and having a good look at it I'm pretty sure i've over spent at $300. I think it's been sitting in a shed unused for quite some time. the table has some surface rust but should be easy enough to clean up a few of the exposed bearings. it does have the mitre gauge but the fence is missing bits.
It does come with the movable trolley - missing one wheel and a bit beat up
the drive pulley has rust and will need cleaning up so it doesn't chew up the belt that i will need to buy. Any suggestions on where to get one? is there a similar automotive belt that works?
the tyres actually seem in good condition, I think there may be some cracking in the bottom on.
the two of the 3 extra blades thrown in are just a rusted mess, there is a new one still in the packet though. Unsure if its even worth trying to clean up those blades.
I wouldn't be surprised if I end up spending another $150 - $200 on it depending how involved I go with replacing the bearings and some new blades. It still works out around half price of a comparable new unit from timebecon etc. Just need to get a new belt and start aligning things to the best of my ability

have a yarn to crapatec they should have drive belts to suit, as for rusted blades don't bother with cleaning in my humble opinion blades that size are not too expensive and you should be able to get new rubber for that size blade and pulley

Yes; unfortunately you paid about twice it's worth. Sorry....
That model is a generic Made-In-China under several brands; we have one at the Bundaberg Woodworkers Guild branded Carbatec. The wheel bearings are standard sized sealed ball bearings you can pick up from any bearing supplier and are probably ok; don't buy them from Carbatec. The upper and lower guide bearings WILL be shot but again they are cheap. If you still have the old belt it should have markings you can match up; if no markings take it to an industrial parts supplier who can measure it up. If you don't have a belt I can get you the size next week sometime when I'm back at the guild.
The saw is ok for light roughing out work but is fairly flimsy; 3/8" blades are about the limit it will take. The fact that the lower shaft is adjustable in all 6 directions indicates that the overall build quality and assembly tolerances were somewhat on the poor side... The adjustment on the upper guide is a PITA, you really need to totally strip it down and clean it up; and reassemble everything while pinching the mating surfaces together with finger pressure or the slop is unbearable. And regularly lubricate the sliding sections with WD40.Nothing succeeds like a budgie without a beak.

that's probably where i'm at with it realistically.
Might be worth just sinking a few hours into it, cleaning it up, replace a few bearings and belt and put it back in facebook for what I paid. Not sure. for the handful of times a year it might get used it might be ok.
re belt:
i've actully found a guy on ebay who is selling belts for these machines (and others) so trying to get in contact with him about getting one with out having to pay postage.

so pulled a few more bits down,
just about every bearings has a nice "click/clunk" feel to it as you rotate them around.... so cactus. local bearing chain store quoted $108, questionable quality Ebay ones came to approx. the same price. the smaller bearing shops I would usually use seem to have packed up shop so will have to do some hunting around to see if I can get them a bit cheaper, or see what I can organise through work or call places like carbatec etc and see if they have a generic bearing that fits. but $108 does replace:
6x guide/thrust bearings (608Z)
2x belt tensioner bearings (6001z)
4x wheel bearings (6203z)
the z in those bearing codes just stands for steel shields, you obviously want some decent sealing on the bearings to stop the fine wood dust chewing them out.
found a new drive belt for $30 from a local guy who is an ex tool repair man in kind of just specialises in belt replacements.

Steel seals aren’t dustproof, which is probably why the bearings are shot

Get “2RS” suffixed bearings not “Z”; they have a rubber seal on each side.
If you get cheap Chinese bearings from Aliexpress or Banggood you’ll get the machine running again at minimum cost, enough to determine whether or not it suits you. If it’s not working for you then you can pass it on at minimum loss. Cheaper bearings will work fine in the short term; only the guide bearings are subject to appreciable wear and load and they can be replaced fairly quickly. It’s worth buying those in a pack of 10 or so.Nothing succeeds like a budgie without a beak.

And do some internet research on how to correctly tension the clades on a band saw. That funny red indicator and corresponding scale that may be hidden on the machine somewhere is about as accurate as throwing rocks with your eyes closed. Half of the problems people run into with bandsaws (after you make certain the wheels are parallel and running true) can be traced back to blade tension, usually not enough of it. It takes some work with precision measuring devices and a calculator but it's worth it in the end.
