Re- rubbering Woodfast Bandsaw wheels
Hi Glock,
Whoa! Whoa! on some of that advice. Slow down and take a deep breath and think a while.
First of all a Woodfast that age will be a cast iron machine cos I've got one. It's well worth investing a few bob in such a machine all other things being equal rather than buy a cheapie if you want to do any serious work with it. It's a case of small is beautiful!
It's essential that the replacement rubber for the tyres be very close to the same thickness as the original or the blade will be displaced in the vertical plane to right or left and you have practically no latitude in that direction before you come in conflict with the sides of the table insert. I guess you could in theory make an off-centre slot in a new table insert to compensate but that's a bu## er of a way to go and you can still get problems with the back guides top and bottom not aligning if you move off the original much.
There's a place in Tassie just down the road from me that can do that job...it's a specialist rubber machining shop. They use a suitable proprietary rubber off the roll, bond it to the wheel after truing the wheel on the metal lathe and then if you want a Number 27 super job they grind the new surface in the lathe with a tool post grinder to have the re-rubbered wheel perimeter perfectly concentric with the shaft. That's how you do a good job and no doubt why the Woodfast price seems a bit high.
Incidentally the ends of the new rubber are butt joined and not joined in a scarf by this business. The bonding agent they use is plenty good for that. If you try a scarf joint then you will have to grind the finished job for certain or you will have a bump or dip with dire consequences for down the track sawing performance.
If you want to E mail me I'll give you the contact name and details. I've had exactly the same job you need done there with excellent results and whilst I watched.
Cheers Old Pete
