Horizontal aluminium dropouts.

Unaccustomed as I am to starting threads on this newsgroup, I have an issue that I'd like to solve.

My main steed is a town bike made around a remotely absurd oversized aluminium frame, with a nexus seven speed hub gear, and nutted axles.

Because of my manly powerful legs, or maybe the size of sprocket I have, I find I often have problems with the axle moving forward in the dropouts under acceleration, or gradually edging forward, so, either way, the chain becomes less taut.

Whenever I am assaulted by the p+nct+re fairy, I always retighten the wheel nuts as hard as I can with the 20-odd cm spanner I use for the job, and indeed, over time, I have probably overtightened it, as the aluminium has been indented with the shape of the wheelnuts, and gouged out where the axle has pulled forward on the drive side. I also am sure that I line up the axle as close to perpendicular to the dropouts as I can manage before tightening, and I check halfway through.

Does anyone have any techniques or ideas for making my axle stay put?

Or, even better, a 46cm black vertical dropout steel eccentric bottom bracket frame that they can sell me for less than the upcoming two months' disposable income (not a lot)? ;)
