I use it for cutting aluminum as well as wood.
Same here, using a Delta 14" 28-206. It's interesting that Delta sells that identical saw with a mechanical speed reducer & labels it "wood or metal".
For cutting Al the blade is lubricated with a bar of bees wax (other lubes may work just as well but bees wax is what I've used for 30+ years). At the current rate of use my 1# bar should last 300 years
There's no easy way to run any type of wet lube on a machine designed to be run dry.
woodworking bandsaws frequently have rubber tires that get torn up by the oil+swarf mixture.
Polyurethane tires are a better choice than rubber, even if cutting only wood. I've run Carter poly tires since they first came out & they're tough as nails.
The biggest issue in using a wood saw for metal is that wood saws aren't designed to properly tension the blade for metal cutting. The work around is to run a narrow blade, something around 6mm, & then replace the stock tension spring with a much heavier die spring. Carter sells their Cobra Coil spring for the Delta & Delta copy saws but it shouldn't be too difficult to find a die spring for other saws.
When the blade is tensioned well above the normal range the wheel bearings have shortened life. Plan on replacing them as soon as they start to sound funny.
