Economical pneumatic power draw-bar for Bridgeport J-Head mills, Runs on pressures up to 90 psi, do not exceed that pressure and it will give you years of faithful service. Uses the stock drawbar. Just screw the 2 extension sleeves to the 5/16 bolts on top of the mill, mount the adapter plate, and bolt the power draw bar to the plate, the 3rd stand is 3/8 shorter than the other two and as you can see from the picture sits on top of the head casting. It can be left that way, or you can drill and tap a 1/4-20 thread into the mill casting and anchor the draw bar at all 3 points. A 3/4 socket is included. Apply air pressure, set the regulator to 90 psi and you are done. Shipping includes full insurance.
There are 12 mounting holes, drilled on a 4.35 inch bolt hole circle. If you have a Bridgeport clone or other milling machine, measure your mounting holes to determine if this product will fit your mill. If your holes do not line up, this product can still work if YOU are willing to locate, drill and tap 2 mounting holes. Please do not purchase this product then email me telling me that it does not fit, I have given you all of the information you need to make an informed decision. You would be surprised at how many machinists don't want to drill and tap 2 holes, and I am not paying shipping for you to "see" if it might work. Measure and be sure, thanks......Karl
