Harvey innovation being copycat by …

[Rich Konopka]

Correct me if I am wrong. Last week I whined about Harveys inflated shipping costs. But this week I am applauding them for their innovative products. Their tin coated saw tables are now being copied by none other..

Powermatic.

Except this seems to be a different type of coating? Both seem short on details, but every TiN coating I've seen has that characteristic golden color. The Powermatic coating is black.

I never thought of tin coated table as an innovation. Maybe I'm missing something here, I look at it as nothing more than marketing besides it looking cool how does it improve a table saw ?

According to the Powermatic ad copy it is magical. I think it will deflect meteor strikes, provides the frictionless plane from physics class, and will keep avocados from turning brown after slicing. Great claims with no detailed info on the actual coating.

It's not tin coated; its TiN, that is Titanium Nitride. TiN is very hard ceramic that bonds well to iron, and so protects against both abrasion and rust. It's also a low friction surface. It's commonly used to coat cutting tooling like drill bits, and also used to coat medical implants because of its corrosion resistance. Elemental tin (symbol Sn) can be used as an antirust coating, but it's very soft. Fine for use in tin cans, where durability and abrasion resistance is not an issue, wouldn't last long enough to be worth the trouble on a cast iron tool surface.

Seems like they may be using a moly-disulfide coating that has been used in aftermarget racing pistons for many years:

Isn't Harvey making Powermatic tools? Not sure I would call it copying when it's the same company building them.

Call me a sceptic, but could the truth be that PM's typical polished finished is becoming too expensive and not having a
"premium" surface wasn't a viable option for PM.

I highly doubt moly disulfide is being used on a saw table top. Moly disulfide is a lubricant coating that actually transfers between the host item and the mating metal. It is not very hard but is very slippery. It is the material used in anti-seize. More likely Powermatic is using a nitriding process. Melonite is a trademark name for nitrocarburizing but many heat treating facilities do the same process without the fancy name. Nitrocarburizing will result in a very hard, dark surface that is rust proof and relatively slick (with a bit of post process polishing). It would be a great choice for a table saw surface.

Along the same topic...What ever happened to granite tops on table saws? Did those that were sold have problems, like maybe cracking?

Not too long ago Powermatic (?) sold a table saw with a thick wood butcher block style extension table. Anybody got one of those? It looked like a neato way to have a useable bench in a small shop.

The whole company went under is the reason granite stopped.

Seriously, when I lived in Rhode Island and was living 1000 feet from the ocean rust was a major issue despite waxing the top of my DJ20, MM16, and Delta saw. It was a struggle especially during the summer

Did you woodwork outside? Salt water fog got in your shop? Moisture control is really quite easy.
