Guidelines for Use
Reduce your stock in small graduations and remember to anneal it every 3rd or4th pass. After each pass, turn your stock 180 degrees for a more even thickness.
Care & Maintenance
Occasionally apply a light metal preservative oil to your rollers to prevent rust.
Always make sure that any metal that you pass through the mill is free of dirt, chips, polishing grits, or other residues that might damage the rollers.
This mill is designed for use with soft metals such as gold, silver, brass, copper, and tin/lead alloys. If harder metals are placed through the mill, or if the maximum thickness capacity is exceeded, severe damage to the mill can result.
Always center the stock to be rolled. Occasionally check the rollers for proper alignment by placing a feeler gauge, or a narrow steel plate with 2 parallel surfaces, between the rollers and sliding it from side to side. Readjust the rollers by removing the T handle at the top of the mill and turning the roller gears by hand.
Step 1. Reduce your stock in small graduations and remember to anneal it every 3rd or4th pass. After each pass, turn your stock 180 degrees for a more even thickness.
Step 2. Remove hex head bolts and washers on the two small gears. Then slide off the top and bottom gears, being sure not to misplace the small piece of key stock within each gear.
Step 3. Slide off the T handle at the top of the mill.
Step 4. Raise the height of the two indexing gears at the top of the mill by unscrewing them counterclockwise. You do not have to remove these.
Step 5. Beneath each of the two indexing gears, there are 2 hex head bolts. Unscrew all 4 bolts until you are able to remove the top of the mill.
Step 6. Lift out the upper roller with the 2 bronze roller blocks into which the roller is mounted. Be careful not to misplace the 2 compression springs that are located beneath the roller blocks
Step 7. On the other side of the rolling mill is a large gear. Remove the hex head bolt and washer at its center. Slide off the large gear, being careful not to misplace the key stock within the gear.
Step 8. Beside the large gear, the crank handle and two small gears are held in place by two hex head nuts and washers. Remove these and slide off the crank handle, making sure not to misplace the keystock within the handle.
Step 9. Slide off both of the small gears. Note that only the lower gear has a slot for the key stock.
Step 10. Take off the gear guard by removing the 3 slotted screws.
In the rear of the rolling mill, there are two holes that contain Allen set screws. Loosen these. You will now be able to lift out the lower roller.
Step 11. Slide off the two bronze roller blocks from both the upper and lower rolls. Insert a new roll into both sets of roller blocks.
Step 12. Now reassemble the rolling mill. Follow steps in reverse all the way back to the beginning. Then go on to step 14.
Step 13. Slide off the T handle at the top of the mill once more.
Step 14. Realign the rollers. Rollers are realigned by manipulating the top gears by hand, and checking with a feeler gauge. When done, Slide T handle back on.
