OK, it's probably not worth trying another batch with what you have there. The pipe work and probably the pump is way too small for the size of the processor.
If you do get a conversion, the most likely thing will be that the glycerin drops out and the pump will only be circulating a small amount of glycerin rather than mixing the oil and methoxide. Also with a very small and slow flow the methoxide (being less dense) is likely to rise to the top of the tank and not get mixed in the first place.
To get good mixing, you need pipe work of at least 1 inch preferably bigger. Try and avoid elbows (sharp bends), use radiused bends. Although you don't have the rating plate, I'd guess your pump is way too small too. Big pumps give quick and more complete reactions. Try and find a pump of least 80 litres a minute, preferably much bigger.
Make a pocket for your temperature sensor, so it won't effect the seal of your processor lid. And make sure you have a lid (you still haven't confirmed your processor has one). It looks like a clip top barrel you're using ... get a lid and make sure it's air tight. Having done that, fit a vent ... VERY IMPORTANT. Run the vent pipe to outside away from windows, people and animals etc.
Consider making a venturi and condenser (loads of information on the wiki ... look at the GL style processor page) This is probably the safest and most efficient processor you can make.
