These days I see most people online replacing the rubber on the wheels with urethane material. Try googling for "urethane bandsaw tyres" or something similar. Its basically a DIY job.

Nice score, is it a high or low speed unit?? Just had a look online, and it looks like Hare and Forbes do replacement rubbers, https://www.machineryhouse.com.au/3wq159, this was a stab in the dark, as I didn't know the size of your wheels.

From what I can tell its variable from 50-3000 ft/min. 14" wheels according to the brochure.

Its three phase which means I won't be able to use the blade joiner even with a VFD.

Have a look at the welder, it may actually be single phase just plucked from one of the three.
If it is 3ph and within the limits of what can be supplied with a single to three phase VFD, about 3kW, you can run it on a VFD locked at 50Hz with no ramp up or ramp down

Hi Guys,
I think that you will find that the blade welder is actually single phase, connected doing the phase to earth trick !
I think that the factory rubber wheel tires were ground down to ensure that they were true to the spindle. The urethane ones will probably have to be stretched over them to fit.Best Regards:

This was also my initial assumption but looking at this plate and the circuit diagram I found on the web,
circuit diagram.jpgbandsaw9.jpg
The welder looks to be across 2 phases(might actually work at 230v with one side on the neutral) and the little grinder motor is 3 phase. Not really a big deal as I have plenty of local saw places that will make me up completed blades. The dream of course is to one day have a shed with a 3 phase supply.
To be honest I was in two minds about keeping this thing as it is a ridiculous size for a home shed but I don't think I could let something like this go. Ill put it on some casters and make it easy to push into a corner when not in use.

Technically the blade welder is actually single phase, just at 415v. You can run it off 240v if you can find a transformer with suitable taps and current rating to step up to 415v. Not sure if it'll work at 240v, as the secondary voltage across the blade will be lower by the same ratio, and if it does weld I think it'll likely pull more current through the windings than intended to compensate. Might not be an issue given the short period of time it's actually energised for, and the 220v version of the BS0 on my Kölle is all very basic mechanical operation - springs and contacts, no electronics to blow up from undervoltage. Might be worth pulling it out and having a look on the back though, it's possible the transformer has multiple taps on it already - can't remember if the BS0 welder on the Kölle had extra terminals for 415v or not.
No real cost saving in making up your own blades though unless you go through heaps - the big advantage is being able to weld the blade back together after the missus snaps it doing woodwork, or cutting the blade to pass through a drilled hole in the centre of your part so you can cut a shape out in the middle without having an entry or exit cut.

Seem to be good quality to my eyes (have plenty of good reviews around the web too), come with a handy little tool and some instructions, and I believe the Startrites were sold in some quantity in the US, so they'll probably have the right tyres for your machine listed as such. I had to measure my wheels, and they happened to have a listing for 15 1/2" x 1" that suited my Kölle - but if you can't find something to suit already listed in the multitude of options, they'll make whatever size you want.
30" is a bit of a honker for home use, but once you start using it you'll never really begrudge it the space, especially given I gather the price was right! I have barely picked up the angle grinder to cut anything out since I got my Kölle, which is good, because not having grinding dust everywhere was one of the reasons I wanted it!

Hi Joe , Guys,
That circuit diagram is a bit confusing !
Showing both three phase 220 and 415 volt inputs and the blade welder as two transformers. Hopefully the transformer for the blade welder does have the taps on it for 230/240 volts.Best Regards:

Mahr dial gauge
This German dial gauge was in a bunch of stuff at a swap meet last year. Cost me $2. The movement is a little slow, like it has a sticky feeling to it , it doesn't jam, it is just slow to return to its zero position . I have carefully tried some cleaning solvents which do free it up for a while, but then it goes back to being sticky again.
