it's to facilitate blade change...
I wouldn't ditch the iron top. Here is how I fixed up my BS, and hooked up DC. It works great.If I make one I’d ditch the iron top and just have the new one I’d make. I looked at it today and it would be easy to remove it from the angle adjusting mount. As for blade change does that insert really help that much? It looks like it’d be possible even if it was zero clearance and non removable, as long as the slot was there to get the blade in.
People use more than one width blade, requiring different inserts for zero clearance. If you tilt the table, the location and angle of the hole in the insert shifts. They sell blank inserts to cover the various situations so you can make a zero clearance cut. This is no different than table saw inserts.I’m probably asking a lot of a little $130 benchtop bandsaw to expect the plastic insert around the blade to be flush with the cast iron surface, but isn’t needing 7 layers of masking tape just to level it out a little ridiculous?
With my recent drill press table made, now I’m wondering if I’d see any benefit in making a similar platform for my bandsaw? About all I do with it is shape irregular parts and cut circles or round corners off with it. Maybe cut an arc a few times a year. I’ve seen the time I wished the platform was larger but mostly I’ve wished a thousand times that insert didn’t cause my workpiece to catch as it passed through the blade. Today I fixed that but if I made a new top without an insert I wouldn’t need to worry with it. Why does it even have that? I don’t see any need for removal. Also if I made a new one I could fasten a vac attachment much easier right below the cut point instead of letting all the debris pile up in the bottom and vacuuming out just most of it.
