-First - make sure to attach the bracket to the motor. Otherwise you will not be able to access the screws to mount the motor onto the bracket (The chuck is applied permanently and blocks it). We would suggest loctite during this stage to help ensure it won't separate.

-After the bracket has been attached - insert the motor in the bronze sleeve. We will use a torch for this but did not determine how needed the torch actually is. It wound up boiling the loctite which was concerning. We also froze the motor to shrink the shaft (unlikely to have mattered).

 Find an anvil like surface which you will rest the bronze sleeve on. Find some needle-nose vice-grips and have it comfortably grip the bronze sleeve while allowing the bronze sleeve to lay flat on the anvil surface. Now heat up the bronze sleeve with some form of a torch and get it reasonably hot.
-We applied loctite to the heated sleeve the the Loctite boiled off under our nose. Yuck. You may wish to try it without loctite or without a torch.

 Once the bronze is significantly heated - take the motors' axle and lightly tap it into the bronze sleeve with a small hammer. I've done this twice and the first time was real smooth and the 2nd one required more force. Just make sure you hammer on the axle and not the motor casing. It is the most intuitive to hold the motor with your fingers and the sleeve with vice-grips and then lightly tapping the axel that sticks out the motor. Having the motor on the anvil and hammering the sleeve might be better. If you need to tap harder - I would suggest holding the sleeve with pliers and resting the axle on the anvil-like surface while being held up with some sort of clamp. This way did seem to work easier.

 I had access to a planer so was able to plane down a piece of 2x4 into the appropriate height. This part actually needs to be somewhat well supported compared to the pump motors. I do not feel zipties would be appropriate. The lathe motor L bracket has 4 holes to mount it to a surface. Unfortunately with a permanently installed chuck - the screw holes are obscured. This means you can not use woodscrews. Instead, you will need to drill out some small holes and use m3 machine screws. We wound up using ones that were 35mm long but they were barely long enough. They required we counter-set them with a hammer. Then we had to use a fine needlenose vicegrip or an industrial tweezer. I suspect you could also use your finger, but you will need to hold the nut on to get it started initially.
-We used wood screws and attached the shim to the backing. This also allows the lathe motor to be adjusted vertically by detaching the shim from the backing.

We had to use normal nuts and bolts do to the placement of the bracket. We marked the holes on where to drill the holes. We then used tweezers/fingers with loctite to hold the nuts in place to get them threaded onto the bolts. Here is a picture that should demonstrate why we needed to use the bolts (vs wood screws)

 This should have all the parts from the lathe kit assembled and ready to mount onto the wood back.
 Now you will need to mount the lathe motor to the backing. The centering doesn't seem necessary, in fact it might be better to not having the motor axle centered in the mixing funnel. Having it offset might increase the turbulence and thus be beneficial. For the sake of consistency we have tried to keep the motor's axle aligned with the center of the funnel. The L bracket should be used for this but you will need to find a shim to mount between the backing and the L bracket. The bracket holds the lathe motor to close to the surface to not use a shim (spacer?)

+[[File:Mixing container bracket work.jpg|thumb]] This image shows the mixing container inside the other support bottle. You can also see the paper towels we stuff between the 2 to help support the inner mixing container.
 Now you will need to mount or support the mixing container on the rigid backing that can also support the mini-lathe motor which provides the stirring action during the mixing phase. The bottom of the plastic bottles should be cut off so that a funnel is created. The larger (outer) funnel will contain the inner funnel and support it. Without this approach, the inner funnel would need a complicated mounting system or be punctured with wood screws to attach to the backing. Having the larger funnel-bottle support the mixing container is easiest as it can be attached with whatever and doesn't need to avoid leaks. It may not look nice but that was never the design goal. This was our first attempt and we're still happy with it. Also - there are paper towels between the 2 funnels. This helps steady the inner funnel.

-Drill out the stopper and insert the tubing into it. Look at the "O.D. outer-diamater on the tubing you purchased. Try a drill bit of that size. Make it so that the tubing does not protrude past the top of the stopper. (This would create an area that won't drain) Push the stopper into the neck of the mixing container. It should form a water tight seal inside the bottleneck.
