Here's a tip to sanding really bad seams...flat.

Sometimes you come across a set of slates that are really messed up, like in this case which was on a GC1-2-3, with mixed slates that didn't match in thickness or in the seams because they were from 3 different sets of slates.

The first think you want to do is level the slates as best you can, while making sure the seams are flat to each other using at least a 2' straight edge. Once that's done, then outline the areas that you're going to fill in with bondo with a marker, then fill with bondo. Once that's done, next comes the challenge of sanding the bondo flat so that there's no ripples in the bondo.

If you purchase a 2' carpenters level with a good machined straight edge on it, then that works perfect for sanding the seams flat if you use it in the way I'm describing.

Glue some 60grit sand paper grit side down in the middle of the level, then glue the same sand paper grit side up on the ends of the level. When you're sanding the bondo, keep the grit side down sandpaper focused on where you want to sand on the bondo, and the grit side up sand paper stops it from sanding at the ends of the level. Once you've sanded the bondo flat the seams will turn out flat and smooth to the point that you won't even know where the seam is.

used in auto body. Nice cause it has handles and you can buy the sandpaper in packets that go right on it.

D-Rock, that's the first thing I thought of when I saw what Glen was doing (I've got an old one out in the garage), but they are not rigid enough, and probably not straight enough. Mine has a foam backing for the sandpaper, which really wouldn't do the job. But a nice machined-flat 1/4" steel plate attached to it would do the job nicely.

Very good junkbond, but keep in mind you have to turn the sandpaper upside down on the ends to keep from sanding what you don't want sanded.

Sooner or later I'm going to come out with my OTLB...oooops...I mean my RKC seam sander & flattener:grin::rotflmao1:...maybe someone:eek:...will beat me to it:outtahere::grin:

Yeah maybe you will come out with a rail ext DVD in 3 more years and a stairclimber in two more weeks And then best of all a
simonis vid with your glue
Down method.

John...the difference between myself and you...is that I'm not interested in designing tools that only YOU would use, or DVDs that only YOU would watch. I'm more interested in this industry as a whole...not just your little area that you work in.

I'm interested in teaching other mechanics how to better their work and understanding of this kind of work...which means...I'm not interested in what kind of tool box they carry their tools in with. See, that's another difference between myself and you, I'm more interested in the mechanic knowing how to do this kind of work right, as opposed to what kind of tool box he carries his tools in...while you on the other hand, are more obsessed with coming up with some bullshit that no one would ever use...but yet it must be good...because YOU thought it up...and YOU liked it...so everyone else must too.

You have what...10 years experience as a table mechanic? I've been working in this trade for the last 27 years buddy, you're not all you think you are to this industry, because if you were...then you would have been the consultant to Diamond when it came time to design their new coin-operated pool tables. You would have been the one that designed their ball polisher. You would have been the one that redesigned the play of their rails.

No John, you're more like a fly... that's always circling a pile of shit trying to figure out where to land...thinking you play a very important role in life:grin:

Glen

PS. Here's one for you John;) A little over a year ago, I held a mechanic's seminar in Alsep, IL. Lots of people showed up...but not you. But, I do recall you making the statement that YOU were going to start holding mechanic's seminars as well....to show ME how it's done....right, the OTLB way...do you remember making that statement...right here on AZ?

When was your first seminar held...to help better this industry?:rolleyes:

Best post I've read in awhile.
Now if I can stop laughing. :grin:
 
I guess thats why I see so many of those guys posting pictures of your glue method, Mine is way better

I have decided to make DVDS to sell with my OTLVISE that cover much on working with tables, working on the last couple now with antiques but that can wait.

SO tell everyone when your vid is coming out from Simonis showing your glue method???????????????????????????????????????

I think they may be waiting for me

OTLVISE allows a mech to move slate just about anywhere without ever having to lift them again. I think thats a good contribution. And its done!!!!

Yeah...yeah...yeah....we all know John....you're the BEST on your small block:grin:...but haven't you heard...talk is cheap:rolleyes: My DVDs are being done right...with Industry support of the cloth manufactues....who's endorsing yours?....OH wait...I forgot...your way is better....because YOU say so:rotflmao1:

Not that it has anything to do with sanding bondo -

but per my talks with Jay and Ivan the DVD is closer to becoming real.
Unless I mis-heard, the contracts have been signed and production is next.

trust me, it works. If you can get a car straight enough for gloss black paint and not see any ripples that is straight. I used this on my entire table to check for unevenness. I put a very light white guide coat of spray paint down on the entire slate. When you sand the paint will come off the high spots immediately, showing the low spots on your table. I don't know if its the right way, but its how its done to get a car perfectly flat so thats what I did.
 
Not sure what started this pissing contest, but lets head it off before it gets out of hand. Insults towards other users because they don't agree with you (or because you feel that they don't impart their knowledge the way you would prefer that they do) are not appropriate around here.
