How to fasten the electrical motor to the bead roller.

What is it I want to build?

 I need to figure out how to fix the motor to the bead roller.

I'm thinking I want to be able to convert the roller back to hand crank use if needed, for example the motor breaks or the construction I'm making does not work, so I will try to make a bolted bracket for the motor.

I need to be able to adjust the motor position to get the shaft aligned as good as possible.

As I will have to dismantle the bead roller and probably need to do some welding to the frame, it would make sense to stiffen up the construction while I'm at it. I think the easiest way to stiffen the bead roller would be to weld square tubing or a thick plate to the back side of the bead roller frame. As I need a way to get the motor more towards the back of the roller a suitable tick plate might solve two problems at once.

The plan is now to strengthen the body of the bead roller at the same time as preparing fastening point for the motor assembly.

Purchasing material.

With some kind of idea of what I needed I made a visit to the local "metal" store to se what they had in stock. This particular store is  such where one is able to purchase only the required amount and they cut the material to desired length. This is convenient in this case as several different dimensions are needed but the amounts are small.

Flat bar piece 180mm X 80mm X 20mm. The purpose of this piece is to offset the motor bracket fastening. 16mm offset would have been enough but this was the closest I could find. I'm sure this could have been made in some smarter way using less material but this seems like an easy way to achieve an offset and get a rigid base for the motor bracket. The plan is to stich weld the flat bar in place.    

Square tubing 30mm X 30mm X 3mm for stiffening the body of the roller. Also here the plan is to stich weld the pieces in place.

Finally a flat bar 150mm X 10mm to make the bolted motor mount of.

As the square bars interfere with my earlier fastening holes I need to rearrange the fastening of the roller to the stand.
