Agreed. The Intruders are usually treated as a throwaway sled, kind of a shame really. If you compare it to it's competition in the 80's it was one of the best. So I started out with a 1/2" drill with a Kobalt wire wheel. Was not impressed, switched to Harbor Freight wheels, they lasted longer but still not good enough. Here's some pics of the results.
I then decided to take my brother-in-law's advice and bought an angle grinder and a knotted wire cup. Huge Improvement! It may not be quite as good as sandblasting or acid dipping but it's a hell of a lot cheaper and does a decent job.
I finished grinding last nite but was too tired to take pics.
I'll put them up tomorrow. Thanks for looking.
