If you meant Caffe' Rosto the answer is unequivocal yes, mod the Rosto. I roasted with a stock Rosto over a year then added a variac thinking to help with cold whether roasting. Marginal improvement since boosting voltage would increase heater and increase fan which fought each other for any real control. Some benefit yes, but not much. Few days later since Rosto fan AC easy to split wire did so and ran fixed fan voltage variac controlled heater for a couple weeks. Much better control! Then added variable boosted fan control. Ultimate control any profile from FR like 6min speed roast to 20 mintute drum style roast. Boosted fan also enabled doing primarily 1/2#/227gr batches the last number of years. Smaller batches of course no problem. Even did a 28gr greens batch for the heck of it once, (enough for one double shot:-) Also did a full one pound batch once, now that was insane for the Rosto size roast chamber and took constant tilt-o-rockin in addition to fan maxed at 144v!

To know I must first not know. And in knowing know I know not. Each Personal enlightenment found exploring the many divergent foot steps of Those who have gone before.

However, your roaster sounds interesting. Please count me in. Thanks.
