So I'm attempting to install a rear Magic Pie Edge on my 2010 Jamis Aurora Elite. I have a sneaking suspicion I may be screwed, but am hoping someone can tell me otherwise. The concerns/issues I have are as follows:

1) Recessed area for nut 2) Axle doesn't seat in dropout 3) Lack of space for inner washer

The recessed area doesn't allow me to install the provided nut as the diameter of the nut is too large. I have seen adapters similar to those used with a trailer that essentially "fill" that gap and create a flat surface to then complete the installation. Is this a solution? If so, could you provide an example product? Can I just stack a bunch of washers or the like in there to fill in the space?

As for the axle not seating---do you agree that this isn't seated far enough down to be safe? Would filing the dropout be the solution here? If so, how much farther down would the axle need to seat into the dropout compared to where it currently is in the picture?

As for the washers....it is a pretty tight fit just setting the wheel in the dropouts. It's a steel frame, so I think i can spread it a bit if needed. Are the inner washers absolutely essential, or more just for spacing to keep everything clear of the frame?

I'm hoping to be able to make this frame work for the conversion, so would be open to any suggestions. Thanks!

Are you using torque arms? the thickness of a torque arm could act like a thick washer to be able to get the nut on.

there are axle washers that are very strong available at ebikes.ca

you can spread the dropouts a few mm to fit washer if it's required to keep chain off frame in use.

It looks like the axle is in the dropout, is it in all the way? if so torque arm will hold it in, if not you can file a bit so it goes all the way in

persevere your almost there

Thanks for the reply. I am using torque arms, but the lip of the recessed area (see picture 3) doesn't allow the torque arm to sit flush. It seems I need to bring the recessed area to level with the edge of that lip before I can attach the torque arms. The SpaceWash5 washer from ebikes.ca looks like it might work if I stacked a couple of them (the recessed area is a bit over a centimeter deep).
 
strong tight fitting washers should get you past that recess, looks like you have lots of axle length to still have plenty of thread for the axle nut

Would the outer washers that are being used to fill the gap need to be flat on two sides to match the axle, or would washers that were round on the inside work since they are just providing clearance? Is there a particular material or class of washer I should be looking at?
 
these washers are usually used on the inside of the dropout to get more space for the freewheel, but they are nice and strong and the right shape, you may have to drill out a normal washer to get a big hole in a small diameter washer,

come in 3mm and 5mm thickness too,

whatever you use they should be well fitting.
