What are the tradeoffs between spiral and shaped dough hooks

Don't know what you are making, but hopefully this will help you make a decision:
Making Bread with Dough Hook Chickens in the Road

Hi Georgette
You need to encourage movement between the beater and the silver shaft it locks on to. There is nothing that you can unscrew to make it easier. Get a can of CRC and try & get it around the silver shaft at the top of the beater plus you should be able to get a bit in that side slot where the beater engages with that driving pin. Rock (twist) the beater side to side and slowly the grip will loosen and you will be able to encourage it off. Once you have it off you will need to clean out the CRC and polish up that silver shaft. Next is the more difficult part, you need to polish up that hole in the beater. What you are trying to do is remove the build up of flour in the hole so that it is pretty much shiny in there again without being significantly bigger than it was originally. I use a rat tail (round) file to do this job, you are just removing the darker build up in there. When done a good wash and dry and it will be like new again. Keep the hole clean of flour and it may not happen again.

Take a look where the agitator pin engages with the dough hook.
Either the agitator pin (sticks out from the agitator shaft) is worn out or the groove in the dough hook where the pin should sit has elongated and worn. Either pin replacement is in order or new hook is required...possibly both.

I had the same problem too. There should be maybe 1/4" of loose vertical play of the dough hook (or similar attachment) on the agitator shaft. The hook locks in place rotationally on the shaft until it is pushed up. Before you try to turn the dough hook backwards in an attempt to remove it, push it upwards and hold it up, then rotate.

I just got my dough hook unstuck! The problem was the bolt at the top of the dough hook. This bolt is used to adjust the height of the dough hook. This bolt came loose while mixing and went up towards the mixer. The force of the spinning actually tightened this bolt against the mixer so when I tried to release the dough hook by lifting and turning, it wouldn't lift. The bolt was in the way! The solution is to loosen this bolt. You'll need a thin wrench that's about 15 mm. You can test loosening this bolt on the other attachments since they loosen in the same manner. You'll have to bend the white shield down slightly to get the wrench in there. It's a tight squeeze even with a thin wrench. Hold on to the lower end of the dough hook and turn the wrench counterclockwise when looking down at it. Once you loosen the bolt, you'll be able to turn the lower portion of the dough hook to lower it. Then you can lower the bolt further. Once you have them low enough, you can remove the dough hook like normal - lift and turn. Sure beats boxing it up, shipping it for repair and paying for shipping both ways!

This is a dough hook and would typically only be used to knead dough. Therefore, the extra clearance makes sense for kneading dough. For other mixer jobs, use other attachments.

IT NEEDS TO PROOF LONGER

if you r using it for dough use the roller and scraper it works much better. But if u want to use the dough hook the holes in the middle is where the knob and stick in the arm go into to hold the hook inplace and it also goes in the hole on the side near the scraper hope this helps
