You stoned everything right to knock off all the burrs? Im thinking if you did everything right on the slide then maybe the cross feed screw and nut are out of alignment. How about putting it back together, oil everything with way oil (vactra 2), do not put in the crossfeed feed screw in and adjust the gib so you can slide in a .0015" feeler gage between it and the top saddle/cross-slide ways. When I tighten a gib like that, I tighten outside screws first leaving the middle ones loose. Using the feeler gage so you have clearance (plus I will attach a You Tube on adjusting gib at end) Then just snug the middle one up. You look like a strong guy so be careful to not over tighten everything.
Then try to slide the cross slide by hand back and forth. It should push back and forth easy. with side gib screw nuts tight also.
Then pull the slide to the front or nearest to the operator. Leave feed screw nut snug so it can self align when you screw in the feed screw. With the slide still closest to you, screw in the feed screw in as far as it will go and it's bracket is up against the saddle. Then tighten up the bracket and brass feed nut. You may have to lift the bracket up a bit as gravity may make it drop a bit. Then it should be OK if that's the issue.
The scraping issue is what happens when you buy the inexpensive machines. Oh you can check the gib to see if its bent by laying it on a flat surface and use a small plastic hammer and tap on it all over. listen to hear if it slaps or open sound. If it is flat the noise will be solid sounding,can also see if you can slide in the feeler gage. Most gibs can be bent back as long as you don't push to hard. Try what I said and lets see if that helps. Rich
The You tube is on a bigger mill and has a tapered gib, but you can do it with the straight gib to on a lathe. Same principal.
It's better to have the gib looser on unscraped ways, so .0005" clearance per side of so oil can spread on both sides. Total of .001" to .0015. Push on it and let go and check the actual slop. You a strong guy and could bend it if you push to hard.
