Do you happen to have a thread on this? I'd love to see it & links to parts of you can.The biggest problem I had with my HF saw was getting the down feed right with the spring setup they use. I recommend changing the spring to a hydraulic setup. It can be done fairly cheap by buying all the parts off ebay. I did mine for less than $20 and now the saw cuts better. It even helped with it cutting much squarer. Too much down pressure can cause a blade to flex to the side. And too less pressure just dulls the blade faster.
