Title: Window channel seal/stainless polishing question.
Post by: GaryI72 on 2013-07-17 08:42
Is this correct. If it is, does the high side go to the outside or inside of the door. Does it need glued in place or will the pressure of the glass lock it in.  Thanks.

I test fit with the glass.  Seems too thick.

Here is what is in the other door.

When I installed my electric window, the mounting strip,channel, and glass were so tight I was afraid I was going to break the glass trying to install it, so I ended up setting the glass in the track with a rubber sealant. What I had was just a flat piece of rubber supplied with the electric windows....was not a moulded shape like yours. Just a guess on what you've got, but it seems to me that portion protruding out the top of the channel wouldn't be doing anything if it were on the inside as you've got it. Does the track the glass sits in come up high enough so that rounded lip would seal against the outer side of  the door?

This is what it looks like with the channel in the door. I'm going to say that the raised side goes to the outside. The seals were from carpenter. It looks like its to keep water from running down into the door.  Not sure if I glue this in place or the window will keep it in place.

If it's tight you shouldn't need adhesive.

If not tight you might want to use black weatherstrip cement (3M).

Thanks for the info. Things are slowly going together.  Working on the stainless for the doors. Picked this up today at Harbor Freight. It's actually a buffer/grinder. I took the grinder part off. Figured it's done after I get the stainless polished. It'll get more use sharpening my blades.  On sale.  Walks on the stand. I put my foot on it to keep it from running away.  A lot of strands are flying off of the loose leaf.  Is this normal or is it an inferior pad? I'm new to buffing so any suggestions would be greatly appreciated.

That's the one I wish I had bought....the longer mandrel is probably safer. I strongly suggest finding a rubber hose that will fit over the shaft in between the wheel and the motor. It will help when the wheel decides to grab whatever it is you have in your hand. I replaced my harbor freight wheels with some much wider ones I picked up at a big swap meet. Wider is better, less of a tendancy to grab the part. The ones I have are probably about an inch and a half wide. The better quality wheels will have a lot less shedding, but I would guess they all do it to some extent.
I can bog down the motor on mine if I bear down too hard...but that's a GOOD thing....once again the grabbing of parts if you catch an edge. This is one case where you are better off with a less powerful motor.
The biggest problem with buffing I think is it is very tedious. I spent probably an average of 2 1/2 hours buffing on each piece. The long rear fender spears probably got 5 hours each at least....and that was just the final buff after many many hours of hand sanding with 400/600/1200/2000 When you spend so many hours buffing, your mind starts wandering and then guess what happens...you catch an edge and, if your lucky, just made a few more hours repair. See a pattern going here with what I'm saying? BE CAREFULL...it's dangerous. I watched a video of a guy making stainless custom window frames. He said he always gets asked why he uses an electric drill with a small mandrel mounted buffing wheel to buff out his pieces instead of a buffing motor. His reply...... he points to where he had 42 stitches in his face.
I do the black compound on the hard sewn wheel, the green or lt. grey compound on the loose wheel, and do my final buff on a small loose wheel mounted on a mandrel in my drill press. The drill press wheel is just used with a polish like blue magic.
If your stainless in in good shape, the pieces you'll have the hardest time with are the windshield trim. They got all the brunt of the head on road debis. I probably spent 40 hours restoring my windshield pieces because of all the small pits. If yours is the same way...give me a holler and I'll tell you what I found as I was finishing up that will make the "many pits" problem a little easier and quicker to resolve.

I use leather gloves to ward off some of the heat.  Cheap ones from Lowes, leather on the fingers and palm, cloth on the back side.  Helps keep the hands "safe" when that mean ol wheel decides to grab the part!
Title: Re: Window channel seal question.
Post by: GaryI72 on 2013-07-28 08:17
Thanks guys. I did pick up some leather gloves while at HFT. I was so excited about my new toy I was out there buffing smaller trim around the doors at 11:00pm and I've found out fitst hand how quickly something can catch and go flying. I'm stepping up from safety glasses to full face  shield. Thanks again.

A few hints...use different size wooden dowels shaped a little on the ends and a very small watchmaker type hammer with a wooden block underneath to work out dents.
Stainless is very hard to sand, so if you have scratches you don't want to sand a large area down to the depth of the scratch. What I do is raise the area from the back a very narrow area following the scratch, actually raising the area slightly above the surface norm. I then  use a good quality (machinist) jewler's file to file out the scratch. You cannot use a normal harware store or HF jewler's file for this..they are too rough and will leave more scratches for you to work out.
After the scratch is out, I move the area back down if necessary and sand and buff. The stainless is very thin, and if you try to remove a scratch without doing it the way I outlined, it's very easy to get the metal too thin.
My hint for cleaning up large ares that are pitted.... Harbor freight sells 4" wheels in a kit with 5 or 6 grits. They are made for the 4" grinder. They are a rubber like composite material impregnated with diamond dust. The two finer grits, 400 and 600, can be used carefully to rmove material much faster than hand sanding with wet or dry paper, and don't leave scratches like a normal abrasive would.
I wet sand my entire pieces with 400 first, finding and working out small scratches as I go. Progress thru 6 or 800,1200,then 2000 grit. As you get finer with the grits, you will find scratches that you couldn't see with the previous grit, so it's a back and forth thing backing up one or two grits to work out a scratch. once that's done it's time for the buffing stages> Man they're sure pretty when you get that final buff done.

Spent quite a bit of time working two small but fairly deep scratches out of the trim that goes around the window vents. Went to polish.  Slips out of my hand and now I have two scratches worse than what I started out with. I think what I'll do is sand, mount the stainless and then polish with drill. Time to push that stone back up the hill.

Do you remember what Harbor freight calls those wheels?  Like to check them out.

just keep an eye out for some wider wheels. The grabbing will still happen, but not as easily.

Not off hand. I'll do some checking and get back to you. Gotta go put a driveshaft center support in my nephews Ranger in the morning. Wished I had seen this earlier..was at HF this afternoon.

Try this site some really good info.  I have polished quite a bit of trim and found this really helpful.
Good Luck.

That would be them. I just went out to my garage to get the item number, and it's the same as in the HF link GaryI72 posted. I should note while reading their description, I noted I eroneously said it was diamond impregnated, but it is actually a carbide

Thanks guys!  Too bad you can't get those individually.  I'd only want the 400 & 600 grit ones.
I have used something like this before when I could get them locally, made by Craytex.

When I was in machine shop, we used a few Cratex products in our deburring department. Might warrant a look at machine shop supply house, or  place like Graingers. The 5 piece HF kit is only 15. or so, Cratex may be that much for one, but undoubtably would last longer. They may even make an 8 inch wheel for a grinder. I havent tried to use the coarser grits on anything..probably will someday on something non automotive.
I found those hf wheels towards the end of my ss restoration, so I don't have a real good feel for how long they'll last, for sure not as long as we'd like them too. Other than hand work, which is a real bitch on SS, I just haven't found anything else here locally that would work, particularly on concave surfaces.

Bolt the stand down on a piece of plywood. You then stand on the plywood and everything should stay in place.

Thanks.  I'll do that.  Just got my wider loose leaf wheel today.  That is a night and day difference from the thinner one. That thin one kept giving me more work to do!

Those seem about useless if that loose leaf thing is what I'm thinking it is.  I've polished tons of stuff with the sewn ones like what I see laying on the bottom or mounted on the right here.

(http://57fordsforever.com/smf/index.php?action=dlattach;topic=4311.0;attach=7397)

The loose leaf ones are just too soft to do any good most of the time.  Maybe useful for some very light final buffing on something that is already polished up real good but sure won't take out any small scratches.

Post by: RICH MUISE on 2013-08-30 06:51
Gotta disagree with you on the loose wheel, Tom. Probably the main problem is the ones your showing in the pic are not effective because of it's narrow width, not the fact that is is loose. A wider wheel will surprise you how stiff it gets once the motor is turned on...almost hard to believe it's a loose wheel. Soft wheel buffing is not meant to take out scratches..only polish. Get  good quality wide wheels and use the sewn for the black or dark brown compounds, and the soft with lt. grey or green. If your happy with what you're getting now, you'll be ecstatic with the new results.

Rich, after doing very high quality buffing & polishing for over 35 years I am sticking with what I've learned.
People still bring me stuff to polish.  I really don't need those soft wheels.
Title: Re: Window channel seal/stainless polishing question.
Post by: RICH MUISE on 2013-08-30 07:30
Well, there's the difference...without 35 years experience I need all the extra help I can get. Obviously, that wasn't your buffing setup in the pic you posted.

No, that was GaryI72's pic from reply #7.  I built my own bench sander/buffer setup years ago.  It uses 2" wide six foot sanding belts & I can quickly attach buffing wheels.
I keep a couple old worn out fine grit sanding belts with a buffing compound run on to them to sometimes do some quick initial polishing before going to the cotton buffing wheels.
