I just bought an old HP saw that is gravity feed or power feed and I got it running with the gravity feed and the vice climbs up so the rock isn't cutting like it should and it binds on the blade . Anyone have an idea what is wrong ?? Thanks Wayne

Climbing vise is a pretty common issue. Some saws use a clip that slides along the blade slot to hold it down. I don't remember seeing anything like that on HP. My old Frantoms had nothing either. I cut by hand without the gravity feed so not much help. Make sure blade is dressed, not dull and feed is not too fast. Cut by hand and listen to saw. You should be able by sound to know when it is bogging down. Then use weight to make it sound like it is in happy zone.

On The E-10 cab unit their is a brass rod under the vise to keep it Sq. to the vise. The gravity feed on mine. i never use it. In 1955 it had a weight over the back right corner. As for climbing the blade, Cutting to fast to much wt. in gallon jug for counter wt.
If you use the gravity feed place rock in vise. add water tell rock moves slowly through the full pass of vise rod run. Then set rock for cut. Most slab saws cut at 7 - 9 minutes to the inch.
Old and power feed. You mean screw feed? Or BBQ motor drive, Are not old HP's.

What i read in your post is your using a Trim saw.

It has a threaded rod and runs with a belt drive motor that is not a BBQ or pellet stove motor , its a little round motor on a sort of swinging mount

Here at Cigar Box Rock the most common thing we found for this problem is a dull blade. To correct it one can use a metal file against the crown of the blade to bring it back to square. Or simply replace it. Matthew

is the metal file in use as a light tap to flatten the edge down, or cutting metal off the kurf.

Or simply make a cut thru a medium grit silicon carbide grinding wheel. Removes a bit of metal, exposes new diamond. Perfectly evenly across the entire circumference of the blade. Something difficult to impossible by hand with a file.

I would like to see a picture of he feed on that saw. I had only one power feed HP saw but I bought it at Desert Gardens and someone bought it before I could use it. I think it had the BBQ motor though. I have had many different arbor configurations on old HP saws including one with a bronze bushing in the table casting so don't doubt they used different feed methods over the years.
