Step 2: A Better Angle
I bent the steel around a yellow guard post outside the shop then welded the ends together.
Mocked everything up to get a good idea of looks, and placement, then started building brackets. The drill motor bracket gave me trouble so I ended up rebuilding it a few times. I'll get better pics of the final version soon. The motor plate is just a simple sheetmetal plate with holes drilled to match the original screw holes for the weedeater mounting.
The black handle on the right will now serve as a battery box and one of 4 legs.
Step 4: Mount
Step 5: Another Mock Up
The chain attaches to the motor shaft before the clutch. The original weedeater clutch engages when the motor reaches a certain RPM and allows it to sit at idle without spinning the blender blades. It also has a female square input shaft that almost matches the blender's input.
The expanded steel messes with picture taking a bit so it's hard to get a good visual.
Step 6: Starter
Step 7: Lots of JB Weld
Step 8: Starter
I guess I should add that I removed the slip function or clutch part of the drill. Mostly to reduce the size. It had springs that press on ball bearings and allowed the outer sun gear to spin if the drill torque exceeded an adjustable set point. I just removed the bearings and threaded a well fitting machine screw in each hole where the spring went to stop the sun gear from being able to slip.
Step 9: Overview of the Innards
Step 10: Legs
Step 11: Fuel Tank
I ordered a weld on bung for Harley style oil tanks for a screw on fuel filler. I'll weld it on the short post, the long one will house the batteries. The original handle with throttle will bolt on it as well.
It's still in process but I did get it to crank on starter fluid.. I've also received the bung and welded it on. (see added pic) I had to add a little support to the motor plate because it bounced around too much. The sheetmetal I used for a motor plate was a little to thin and it flexed at idle causing the entire get up to walk around. After adding an angle bracket for support it's quite stable. I'll pick up some rubber feet for chair legs the next time at lowe's.
Next step is to solder on two nipples for the fuel supply and return, then rig up a base of some sort for the bottom of the blender to rest in.
I didn't get pics of the process but I pulled the blender motor apart and pressed the motor shaft off the armature. I cut the motor shaft down to fit the old weedeater's clutch output.
