How much heat sink is necessary? - Page 2

ultrachrome · 23rd February 2003, 05:21 AM

Can you recommend a blade for both? I have the 12" dewalt and I tried using a high speed metal blade (composite) I had lying around. It wears too quickly to cut my heat sinks so that the motor housing touches the material before it's all the way through.

I thought about just renting a 14" chop saw from Home Depot which should have no trouble even with blade wear.

Thanks.

12 inch chop saw is compound miter, not abrasive saw.
I use Dewalt # DW3229 80 Tooth triple chip -5 deg rake.
They retail for about $85.00. The anodizing is very hard, so try to push through it quickly or it will dull the carbide quickly. But don't be too agressive or it may bend the fins and bind. That would be bad in many regards!
