Re: Trying to figure out this glass process

In the early days of sand blasting, various things were used to create something that would protect the glass from the sand. Almost immediately, inventive processes were dreamt up by tradesmen to save time on duplicate designs. India rubber, and thick parchment stock soaked in varnish were just a fe...

Re: Trying to figure out this glass process

I have the answers for you on these signs. I replaced the same type of back lit glass signs to replace the broken ones in The Union Station in Los Angeles, California. I did them when I was in my previous shop back in 1993. They were for the Western Union booth areas. Your panels in your photos are ...

Re: does size matter ?

Here is a good thing to try. Sand blast some glass, and experiment with depositing measured thicknesses of wet glue. See how thin you can get it, and still have it chip the glass. You will find that the dried glue layer can be so thin that you can see the sand blasted glass finish actually appear in...

Re: does size matter ?

When chipping fine/small areas, it is best to put the glue down thinly, otherwise it is too thick to fracture into nice segments. Instead the glue layer has too much strength due to its excess thickness and will pop off like a larger unitized "potato chip" of glue. In fine areas you want the glue to...

Re: Spatzier

Also, this is a nice lathe, but it is mostly for doing light weight engraving work on glass art and glassware. It is not intended to turn the larger stone wheels used for Brilliant Cutting as that seen done on large glass panels by DAVE SMITH in Torquey UK. But it can still do some nice cutting on a...

Re: Spatzier oil

Hi,
Use a "non detergent oil" in your Spatzier. According to Jim Riser, detergent oils allow debris and dirt to be suspended in the oil, while non detergent oils allow dirts to sink. This is probably why you discovered so much sediment and sludge in the bottom of the bearing cups.

Re: Novice glass chipping (build chipping/drawing table)

Also, I noticed that there is still a lot of remaining sand blast in your designs that did not chip. The glue lost it's grip on that glass because it was not fully dry. Sometimes this is caused by force drying the glue too rapidly which dries the top of the glue before the bottom fully dries to the ...

Re: Novice glass chipping (build chipping/drawing table)

Good to see the progressive steps in your learning process. I think the 180 grit abrasive is a bit too fine for glue chipping. It does not fracture the surface of the glass as well as 100 or 120 grit will. They also give a rougher surface for the glue to bond to. The courser the grit that you sand b...

Re: Oil size problem

If you can break the surface of the Sherwin Williams with lightly rubbing it with some #000 steel wool pad that should keep the size from rolling back to itself. I have to think that if the SW paint repels the size when it's wet, that the final dry adhesion is also jeopardized. Are you certain that ...

I am actually also interested in applying this nickel to metals as well as glass. A thin deposit of nickel onto the metal, and then an automotive clear coat for protection. I have an idea for use in lighting fixtures, as nickel metal color compliments etched glass very well.

Re: glue chip drying

A 1/16" dry layer of glue is pretty thick. And 1/8" is stupid thick. You will get nicer brighter tighter chips if you scale back on your thickness. At 1/8" thick, the glue can actually break your glass by curling it up. Do yourself a favor and experiment with as little glue as necessary to get a chi...

Re: Novice glass chipping (build chipping/drawing table)

You are depositing too much dried glue by volume on your glass. You might want to add just a bit more water to thin the mixture down a bit. When your glue curls off in a single long piece as seen in the photos it is a sign that you are applying the glue too thick. As you can see, there is a consiste...

cleaning depends on what the nature of the contaminates are. Is the glass in an office, or a diner, is it within reach of the public? It can also be affected by any attempts by the customer trying to clean it with (God only knows what) soaps and solvents before they gave up and decided to call you (...

Hi Terry, James' wheel leading info there, mostly shows the leading on tapered pointed threads.

One easy solution is to spray the paint on with an automotive style spray gun. That will eliminate the brush strokes, and if you backlight the panel while spraying, you can control the evenness.

Re: Copper backing Thickness

I think to achieve any copper deposit thicker than using dissimilar metals to deposit the copper will require electrical current. At some point, past depositing a thin

smooth copper layer, you will begin to see nodules of copper begin to form.
