Resin is bad for your teeth


I'm known for and enthusiasm for cutting up those nice ready-to-plonk resin buildings, and turning them into something the manufacturers never envisaged. 

This work tends to be carried out on a cheap mitre saw setup. In the garden obviously, because the process is very messy and you don't want to be ingesting quantities of the dust. 

The problem is, resin is hard. And it doesn't do the saw teeth any favours. 

Hacking away at some wood last week, I was aware that the saw was wearing its way through, not really cutting. Running my finger gently along the teeth provided an explanation. At the ends of the blade (left above) the teeth were sharp. In the middle (right) not. 

I've not used this blade much, but changing it improved things a huge amount. I'm glad I had a spare on the shelf!

I remember my school woodwork lessons from 40 years ago....always use the full length of the saw blade. They put teeth right at the ends for a reason....

If you can get one in the right size for your saw, try an Eclipse HSS one (the blue ones)rather than a chinesium one. Just be careful not to bend them as they tend to snap.

Those saws work so much better if you clamp them down so that they don't move.
I doubt that you could use (I can't) the full length of the saw blade unless you clamp the saw bed.

Normally, I do clamp it down as you are right, it makes them much easier to use. For the photos, I needed it in the middle of the table for a less complicated background.
