Quoted from pinheadpierre:
Thanks - that second video was helpful. I have polished old ball guides, side rails and lock bars before. It seems like in order to get a mirror finish on the new guides I would essentially have to go through the same process I would with the old original guides? If so, I'll need to consider what level of finish I want for the final look and weigh how much work getting new ones would actually save me. Is that right or am I missing something?
Quoted from j_m_:
if you have the right tools, its really not that much effort (as seen in that 2nd video)
btw, if you go to their link, you'll see that their product is just a bit overpriced for what it really is. $1,000 for a suped-up grinder? the same results can be achieved with 200, 400, 800 and 1200 grit sandpaper and a decent belt sander. then just finish it off with the proper rouge and a buffing wheel
personally, I like the grained look (which is a lot easier to achieve with 200, 400 and 600 grit), but like every ball guide, you'll start seeing "ball trails" as the ball polishes that tiny portion where it makes contact with the guide over time
Ball trails in stainless are easily polished out.
I took one of the pieces I got in the mail and hit it with the buffing wheel. It did polish up nicely. The scratches polished up, too. This look may work for some of you. But if you want mirror finish you will need to sand with progressively finer grits of sandpaper---sort of like that 2nd video. Only you will have to do it all by hand because your parts are already roll formed and the rivets are installed. You will not do any machine sanding on that. It is all hand power, baby.
Plus, for the largest piece, the ball inlet guide at top of the play field, for safety's sake you need to make a wooden jig to screw it onto, otherwise you risk having the buffing wheel grab it, bend it, twist it, and throw it across the room and possibly make injury to you.
Can they be mirror polished? Sure. And I will have to do that. But I figure 4-5 hours of my time for each set. Figure $20.00 an hour, I would have paid a bit more for mirrored units.
The construction quality is simply fantastic ! The way the rivets are set on the backside very clean looking. If you have no problem with grained surface you will do fine.
