Thread: Firewood saw

You'd be far better off sourcing a dedicated blade rather than the Lucas blade, you should be able to get a tungsten tipped blade that is similar in profile to the Lucas blade but with a lot more teeth so that you can sharpen it with the same grinder for the Lucas blade

It's what I would do if I was to go down this path.

Thanks DJ, what are your reasons for saying grab one with more teeth, is it speed of cut? Speed is not overly important to me and I was of the understanding that I could get away with a smaller engine if I had less teeth (I know that this is the deal with ripping so figured cross cutting would be the same).

Any one want to hazard a guess on engine size, or know what they are called?

Do you have a mitre saw of any description or a tablesaw? Try putting a ripping blade of 10 teeth or less in and crosscutting a good old bit of hardwood quickly and then try it with a crosscut or combination blade with 40 or more teeth, the difference is astronomical

I've seen a 5HP RAS which was set up for ripping with a 14" or 16" blade that had 8 or 10 teeth on it changed back to crosscutting for a quick job and I'm not kidding, the bloody thing stalled on abit of 200 x 100 Cypress.

Just because it has less teeth, it doesn't mean it needs less power, in fact it goes the other way especially with crosscutting, the less teeth there is has a greater tendency to dig in to the wood as you're not peeling the grain away as you would with a ripping cut,it has to slice through the grain whereas when ripping it's only peeling the grain

g'day burnsy ,the blade should be full tooth and negative hook for fire wood ,don't be tempted to use a skip tooth blade ,all your cuts for firewood are cross cut i e across the grain .

Makes sense, thanks guys.
