Topic tags/keywords: heat resistant wood handle fire

I’m after any advice for what would be the best type of wood to use to replace a handle for a Pyroclassic IV wood heater.

It is close to the glass window and is mounted to a steel plate with a Kaowool gasket via 3 self tappers.

The issue I have is that the heat from the fireplace has chard the wood via the self tapping screws which has crystallised the screw holes so the screws have come loose. I have removed the handle and rotated it and created 3 new holes which worked for a couple of months but the handle has fallen off again and if I scratch the wood where the screw hole are, it just breaks away.

I can get a fire blanket of Kaowool to create my own gaskets, but I’m after a type of wood that has a better resistance to this happening all the time.

Replacement handles are available here:

If I’m having to rotate, then replace these every few months, it’s a pain and will add up over time so I’m after something I can knock up that can last a lot longer.

I am based in Australia (WA) so that may narrow my choices to what’s available here.

Also, if I make my own, I take it that oiling the wood would be better that vanishing given the heat it would be exposed to, or is there another treatment I should be looking at.

Thanks for any help in advance.

Regards,
Damo

Ipe and Cumaru have a class-A fire rating. I would look into them. They are South American woods, but get used for decking and so may not be hard to source.

Is there a particular reason you need to use wood at all?

It seems like a poor fit for an application exposed to that much heat.

What other material would you suggest? Don’t think metal would be any good as it would get too hot to touch, plastic would be a lost cause, so sticking with wood, but getting a hardier fire rated wood seems logical to me, but I’m open to any suggestions.

Is there a way you can use nuts and bolts instead of screws to attach the handle.

If you go with wood, you might look into pen blanks, about the right dimensions and many of the more exotic, possibly more heat tolerant species are available.

That’s the ticket. Two bolts about 2 1/4” (60cm), 2 nuts, 2 standoffs 1” (25mm), 2 lock washers, 4 flat washers and one piece of wood about 1” OD or square or rectangular. Drill appropriate holes to match fireplace, put one flat washer on each bolt , put bolts through holes drilled into wood, put other flat washers on bolt, insert bolts through standoffs, insert bolts through fireplace door, put on lock washers, nuts, and torque to whatever feels good. Should last a few years before you have to replace the wood.

My BBQ has this arrangement and is stored outdoors. I got it at the turn of the century, and it’s still ok other than one handle rotting and breaking off. ......... Jerry (in Tucson)
