Demonstration Information from May 25, 2024, by Larry Sefton

In the first half of the demonstration, I made a shallow wide rim bowl. This versatile wide rim bowl is made from easily obtained wood and can be left natural or enhanced with embellishment. For the more experienced woodturners and to inspire the newer members, I shared a few examples of how the bowl can be modified/embellished to the extreme.


In the second half I gave a brief overview of pyrography, showed the making of a pyrography stamp/brand, covered how I do my pyrography, opened the floor to questions, and lastly shared the method of doing large scale pyrography stamping.


I briefly outlined the making of the hand piece. If you would like to see the making of a handpiece from start to finish, contact Rick Gillespie and he can schedule a short demo on the making a hand piece. An alternative is to contact Bob Wolfe and suggest that MSWG setup a Hands-On day where those in attendance could make their own handpiece and learn some tips.



Examples of my previous work shared during the meeting:


The photo below is of the finished piece started during the demonstration. This bowl has been donated to MSWG (c/o President Bob Wolfe) for the 2024 Annual Christmas Auction.


As requested, below are some of the resource items seen in the demonstration.

Some of these items you may want to purchase with your friends to share in the cost.

The Leather Strop I used to clean and hone the tip was made from this kit. I glued the leather to plywood then cut it in half. One for Green-Gray and one for White Polishing Compound. However, turns out I only use the Green-Gray one.


Amazon - BeaverCraft Leather Strop Kit for Knife Sharpening Carving Knife Strop with Green-Gray & White Polishing Compound - Leather Sharpening Strop 2-sided 3 x 8 IN, Leather Honing Strop Block LS2P11


"One method used to clean and restore tips is a cleaner pad that has very fine abrasive (600/800) grit bonded to both sides of a foam core pad.  This is fine enough to clean your tip without removing metal and is still enough to redress a dulled tip.


Another method is a leather strop to sharpen and buff out an edge.  The strop can be treated with a bit of Neat’s foot oil or a very small amount of polishing paste or extremely fine honing compound.  Use care, too little is better than too much when it comes to burning tips.  Work the tip cold, and with tip on its side, use gentle draw strokes with a finger lying over the upper side of the tip to support it.


As I burn, I keep a piece of old used denim trouser leg (faded) on a flat surface nearby and occasionally wipe my hot burning tip quickly from side to side on it, and this action keeps the pen clear and buffs as I work.  Don’t dawdle as you do this wiping action from side to side, or you will char the cloth, build up residue on the pen tip, and suffer the smell of burned cloth!" Excerpt from the Power Carving Manual review of woodburning tools.

Following is to answer Richard Hiller's questions on the transformer and amp draw:

I am using a 200VA - 110/120 or 220/240 Volt input 50Hz or 60Hz

Dual 4.5 Volt Outputs

Series connected secondaries:

9 volts, 22.2 amps max rated output

Parallel connected secondaries:

4.5 volts, 44.4 amps max rated output


Using the branding/stamping tip seen at the demonstration (see below) the amp readings are below.


Factoid nichrome wire operates at red heat (roughly 1500 °F)

Input voltage 120 at 1.3 amps (see meter reading below and must divided by 10).

Output voltage 4.5 and drawing 19.3 amps.
