Actually the Briggs Hone and the Lisle hone are setup the same way. Two stones and two wipers. The stones does the honing and the wipers both stabilize the carrier and cleans the bore wall. Now this cleaning is not completely done so once the oversize piston drops in you want to clean the bore and check it size by either using a micrometer or inserting a ring and measuring the end gap for minimum clearance. Also cleaning the cylinder will you know if you have good clean hone job as the grit will fill in the imperfections. I have hone cylinder to oversize to only find that there was a hidden air pocket in the cylinder wall left when the cylinder was cast.

Lisle 15000 Ridge Hone

It does require a low speed 1/2" VSR drill (0-500 rpm) or drill press. You definitely want to keep the max speed down as it will gall the bore if ran to fast. You will also need to secure the engine to it from rotating as quite a bit of torque is involved. Both hones has a micrometer adjustment to set the stone pressure and to increase as bore enlarges and the stones wear. Using drill will make your back hurt as it takes a long time to hone these cylinder to the oversized and I would highly recommend using a drill press.

The ridge hone picture is the Lisle 16000 which is for smaller bores 1.75"-2.75" depending which stone/wiper set you use and there is the Lisle 15000 which uses different racks as you do bores from 2.75" up to around 10" diameter bores when appropriate racks and stone/wiper set.
