I know I've had problems finding a pyrograve for years now. I was playing around in google and hit a goldmine. Its called http://www.woodburning.com/" TARGET="_blank">

They have a whole bunch of different pyrograves and tips you can get off them. I noticed that they are only located like 15 minutes from me so I'm going to see if they have a store front or not and buy it there instead of ordering it.

Howdy Scott,

I've used a woodburning tool as a pyrogravure for years....I actually bought mine at a garage sale back then for .50 cents (the box still has the little white sticker on it that reminds me ).
Mine is made by a company apparently called N.S.I., which probably stands for National Science Institute or some such).

Tread.

P.S. Be careful though. The woodburning pens get pretty hot. I installed a simple inline reostat on mine so I can control the heat output. Otherwise you take the very likely chance of destroying the plastic you're working on.....

Most of the wood burners they sell come with restats already to adjust the heat

They do have a storefront/warehouse and the prices are 20% off what they have on the website

I bought a cheap wood burning instruement for around $10, and it comes with about 10 little brass shapes and also a fitting to hold blades. It is very warm and no heat controller. But it is possible to sort this out using a dimmer switch ... can be bought in a "lights" shop or good electrical stores

Good news then Scott. Since mine is quite old (I'm sure it's from the sixties at least), it did indeed have no heat control whatsoever. It was either 'on', or 'off'......period.

My attempt at warning you was meant as an assist only.

Glad you were able to find one that has been obviously upgraded the way they needed to be.

Tread.
