Help! Router burns?
Please can anyone help me? I'm in the process of making 3 bases for 3 carvings that I've finished. One base is blackbean - 2cm thick - I've just gone around it with a router and it's leaving burn marks! I used a ryobi TR-50A which is just a smallish hand held router. I tried to go very slow - the shape of the base is sort of a wobbly oval. What am I doing wrong? The next two I have to do are blue gum - which is even harder wood. The router bit is reasonably new- don't think it's blunt!
Not sure what I'm doing wrong. I don't router very often. Can anyone shed some light on why it's leaving burn marks please.

It's usually caused by going too slow!
Try and move the router a bit quicker. If it's still burning, then try doing it in sections and allow the bit to cool for a second or two in between passes."I don't practice what I preach because I'm not the kind of person I'm preaching to."

Oh really! It's just such a scary machine to use.... I try to be very careful. Thankyou so much silentC.... I'll just build up a bit more courage and attempt the blue gum one's.
Thanks again.

What silentC said.
Go faster or go shallower (make 3 passes) or pause between cuts (best).
The deal is that if you go hard/& deep,
you can cook the temper out of the very fine edge of the router bit.
That softens the steel and the bit dulls XXX-quickly.
The rest of the bit may look fine but the 1-2mm that really matters have gone into orbit.

Oooo.....ok. Thanks Brian...will take all this into account. Now I know a bit more about the way it all works I can be careful of the pitfalls. Just one question.... if the wood is harder and denser does that mean the bit would get hotter quicker???

I can only imagine that it would as there's more work to do.
Like wood carving in really hard woods = go shallow, take less in each chip or shaving.

OK.... the next one's I'm doing are blue gum. Just cleaned them up on the belt sander and had to change belts to a lower grit as the one I was using was hardly scrapping the surface....so the blue gum is pretty hard. Thanks Brian.... I'll see how it goes with the router....

Yes, a really sharp bit, and very shallow passes is the way to go with a router !
