He doesn't give lobe seperation. I'm on my own there. We have tried changing cam timing but its the best where its at. The tractor runs pretty good. Just would like to tweak it alittle to see if we could get more power. We won the points for the class on Saturday. So its doing pretty good.
Ok thanks. The guy I have designs the lobe and then gives me a table for the lift at every degree. He charges 88.00 each though which really isn't too bad. I then use his numbers and make a cad drawing and then use cam to program the cnc mill to cut the lobe.
I have never made a model engine but I have made a crankshaft for a pulling tractor. It weighed 800 lbs when I started.
Now I am working on making a camshaft. I have a guy that will design the lobes but he charges 88.00 per lobe. I seen where some of you were using a spreadsheet to calculate...
I am late to the party but I am currently building a camshaft grinder. I machined a sample model cam lobe on a cnc mill to use to copy and produce a master lobe.
