Re: Bandsaw Power Feeders - in practice
|
I don't want the feeder to be too fast, but bandsaws are so finicky at the wider boards when trying to maintain tolerance. Yes, the "rated" lowest speed of 3.3fpm measured in the ballpark?of my real-life check here around 2.5fpm using some "close enough" calculations, so around 3fpm is a good figure.
Am I crazy? Doing something wrong? When I watch youtubers do hand feed resawing wide boards for fine-finish cuts, they are often just creeping along.
I'll take your vote for VFD manipulation. If I still have enough available torque and can slow down motor 50%, I bet I wouldn't be complaining, but it seems drastic and a thoughtfully designed power feeder would?already have the range accounted for. But like many things, I always?seem to push the design envelope limits any project I take on, it's my curse.
Brett, ? ShopGear has it's speed?as:
*Similar to the AF19N Resaw Feeder with a larger motor, roller, and variable speeds. - Variable Speed - 3.3 - 98.4 FPM
3.3 FPM is too fast?? Did you get the 3ph version?? ?Your thought on putting in on a VFD would be the easiest to slow it down even further

All,?
I've mounted a Comatic AF110N to a Laguna (ACM) 24" (600mm) x24" bandsaw.?
The problem is it seems to feed too fast for most of the woods I actually want to use on a power feed. I'm talking about long boards?usually full widths 6"+ for stock preparation and veneer slicing. The blades are getting pushed back with excess force to the guide blocks rather than a smooth, tuned cut. When hand?feeding the "natural feeling" is nearly always substantially slower than the power feeder can provide and I get great results but it's slow pace. Anyone else have issue with power feeder speeds not going slow enough?
Attempted solutions: 1. Tried a variety of blades, widths, thicknesses, kerfs, pitches, tooth conffigurations, haven't found?one that seems "better" other than a sharp, new blade with resaw design variables, but not a lot of difference. 2. Replaced guide blocks from rollers to full OEM Laguna Ceramic - they are holding strong and not moving.
Considered solutions: 1. Increase blade speed. REalizing that sheaving-up may also result in the need to add motor horsepower (currently 5hp 1847TC frame)
2. Put the power feeder on voltage/frequency regulation to slow it down beyond the mechanical?reduction already bottomed out
3. Get some help from the experts. (This is the cheapest and easiest and why I'm here).
