A New Way to Bind Up Your Work

Keeping pieces together for cutting, drilling, or grinding on a flat lap or Rociprolap can be tricky. Putting multiple pieces together in a Rociprolap saves time and money but it can be tough to make sure they are held together well.

That’s where our new waterproof masking tape comes in.

With a strong waterproof adhesive that is residue free and repositionable, this is a great tape for bonding pieces together in a Rociprolap, or marking the surface when a piece needs to be cut or drilled to reduce edge chipping. Easily removable with no sticky residue on the surface of your glass these 2 inch by 163 foot rolls are the perfect coldworking companion.

The Importance of Routine Maintenance

Many of our tools work right out of the box with little or no setup involved but most of the equipment will need some routine maintenance to keep them running well.

Sandblasters are an important piece of equipment to keep an eye on. All our blasters are siphon feed systems and work very reliably but you do need to keep watch on your nozzles.

In the photo below you can see a side by side of a tungsten carbide sandblast nozzle and metal orifice that fit into the blast gun assembly.

The metal orifice and nozzle on the left went far beyond their useful life and the silicon carbide grit wore through the nozzle and the gun assembly itself which necessitated replacing the entire gun assembly in the sandblaster rather than just replacing the orifice and nozzle.

Routine care of your equipment can prevent costly replacement costs so be sure to check your pneumatic grinders to make sure they are well oiled, make sure the water sleeve on your Covington grinders are greased once a year to prevent the bearings from seizing up. Make sure to read all the instructions that come with your grinding equipment and if you have any questions about routine maintenance, we’re always here to help by phone or email.

Fingerprint Proof Your Blasted Boro

Sandblasting boro glass is becoming increasingly popular, but with that popularity also comes some drawbacks of only being able to sandblast the surface of the glass.

Water spots and fingerprints are the eternal enemy of sandblasted glass giving it a mottled and disasterous surface appearance after only a few handlings.

But what can we do about it? Sandblast coatings aren’t a good solution for boro items that will be heated up by customers as the coatings can burn off and the fumes could be toxic or, at the very least, smelly.

While glass acids will not frost borosilicate glass, perhaps you didn’t know that it will still etch the boro. By etching the glass, we mean that it will still remove glass from the boro but it will not frost it. Our picture below shows a boro rod that was submerged in our Vari-Etch liquid for about 5 minutes. The surface is perfectly clear as the acid will not frost the boro.

That doesn’t mean that Vari-Etch is completely useless for boro glass though. If you sandblast your boro glass for dimensions or designs, you can then use the Vari-Etch material to etch the sandblasted surface and fingerprint proof your sandblasted areas without worrying about trying to coat or seal the surface of your glass.

In our photo below, you can see we have sandblasted the end of the boro tube. We then submerged part of the tube in our Vari-Etch liquid for about 5 minutes. You can see on the surface only where we touched the sandblasted area of the tube once and it held onto the finger smudges on the sandblasted portion, but the portion of the rod that was sandblasted and acid etched did not retain the fingerprint smudge at all. There is even a finger print smudge that is halfway onto the sandblasted area and half way on the sandblasted and acid etched area so you can see how effective this process can be for maintaining a clen surface on your boro.
