You'd need to slow the saw down from its current 800 fpm to about 100/150 fpm. There's no easy or cheap way.
It's theoretically possible to change the size of the driving wheels and belt or fit a variable speed inverter drive and new motor. Neither method would be economically viable. You'd be be off buying a purpose made metal cutting bandsaw.

For occassional use I saw some pics from a guy who made a frame and mounted two homemade wooden pulleys with bearings inset to get the right ratios and bought the approprate sized belts. He said worked very well.
Just an idea... I think pulleys were made from 18 or 25mm plywood but possibly mdf may have been used.
shouldnt cost much with those materials if you have some offcuts.

Yup my large pulleys are mdf with the very small one made from steel.

The OP machine is 800 METRES per minute or 2600 fpm. for steel cutting, around 100-150fpm is needed
The combination of pulley change and inverter are needed to get enough speed reduction to get one machine switchable between wood and steel cutting (with a change of blade too)

Okay guys, thanks for the input. I was thinking that I would use it to cut some metal bar to make my own 'T' nuts.
I can see now that the whole idea is nuts and I will just buy them

Unless you've got "millions" of T nuts to make, why not just use a hand-powered hacksaw? Fitted with a decent blade (probably 18 tpi will be best) and a decent "don't rush it" technique, you'll be surprised how quickly it'll be done.

I usually rough out my T nuts with an angle grinder and finish them with a file.

Yup, that would work well too.

I've done them now and did use a hand powered hacksaw as I only needed 10 nuts. The idea of a metal cutting blade for the bandsaw interested me as much for the future as for this job. I am going to forget the whole idea now and just do what I have always done - use a hacksaw. But thanks for all the suggestions,
