Sanded the first table top today with the BS105 and the result was a clear 10/10.
Under very close inspection out in the sun, it was impossible to find even the smallest evidence that it was sanded using a belt sander with only 60 and 80# belts.
It was as close to perfect as you could get. Identical to the result of puting it through an expensive drum sander with an 80# belt. Just perfect.
The sanding frame is the key (big - 390 x 235mm) Its perfectly parallel with the sanding platern and can be adjusted easly by 0.1mm. Sand some pre veneered board and stop moving the sander and leave it in one spot for a minute and it will only skim off the amount you have dialed in. Its a pearler.
Sanding the top today, with a flick of a lever you use it on normal mode with 60# in a cross thatched stroke quickly just to roughly flatten and take the edges off, then pencil marked it all over, and a quick flick of the lever to engage the sanding frame and straighten up to sand the pencil lines off.
Changed to 80# re-pencil and take your time (around 15-20 minutes i spent for the 2mt top) and straight up and down and it will blow you away at how "flat and scratchless" the top quickly becomes.
This is one massive, heavy, awesome beast and will give you fatigue, but the results are so impressive.
If an expensive drum or wide belt is out of the question (and you can get access to this sander) and you have a few muscles to lug it around, go see your bank manager and grab the mighty BS105.... You wont be dissapointed ;D ;D ;D
