HANGING A LINE SHAFT
RETURNING TO LINE SHAFT DRIVE
I have always had this machine powered by v-belt drive motor to tail shaft. recently, I dug out the line shaft pulley for it. It takes a 14″ x 30″ on a 300 rpm line shaft. It is shown here for scale. It is twice the drive width on account of the tight and loose pulley on the tail shaft. Soon, the motor will be gone and this machine will be run from line shaft again.
This is the line shaft I am getting ready to install to put the 8″ back to line shaft drive. The Fairbanks Morse motor will drive this shaft rather than the molder. This is a section of the 110′ that was in the plant from which the 8″ molder came. The couplers are numbered. This section has a long key way which I believe was where the steam engine drove before they put in the big electrics.
These are the babbitted hangers for the line shafting. Shims removed. I am getting these ready for the installation. The grease cups are an upgrade from oil. I think they required less frequent attention, being self feeding. But, I noticed while cleaning these that the grease had glazed and hardened. I am thinking I will stay with the grease but also utilize the oil cups which are bored each end to flush with kerosene from time to time.
Line shaft section lifted into place with the help of friends.
Split pulley placed and ready for positioning and tightening up. The motor is on the other side of the wall. There I will add 11′ of line shaft later.
This is the pulley for the 12″ 505 molder. An interesting case. Two different styles of pulley combined and united into a larger, stouter pulley. Why? I have no idea. Low on stock? Speeding up the machine relative to the others? The 505 replaced an older machine with different tail shaft speed requirements?
Both 8″ and 12″ molder drive pulleys in place. Coupler for the next length showing on the right.
“Prudent” says that looks nice, now let’s go home.
To go back to line shaft drive we returned the loose pulley to its position and filled it with oil.
The belt I selected for this drive was very oily. So I had to clean it. Sawdust rub and an acetone bath.
Hey it works! Need to clean the belt some more. The belt is in the run position on the wood pulley. It is twice the belt width to allow shifting to the loose pulley.
Time for some belt guards once the kinks are worked out. “Prudent” says “this is neat but I’ll be moving on through”. She also says, “Dan will like this”.
The next length of line shafting requires two bearings. One in a wall pocket. The structure will be diagonal braced once I have the shafting running smoothly.
The loft over the 505 begins to take shape. It will be for storage, to support some of the duct work, and will carry the rip saw counter shaft.
Well the next length is up and running. The 12″ machine still waits. It will be a little while because I have a slight kink to get out of the shaft in the area that the pulleys go for the 505 and the rip saw. Sooner or later a metal whisperer will show up and fix it.
Meanwhile, nothing but time is in the way of getting the 6″ Houston in the foreground on line. Take away the electric motor guards, rig up a shipper, hang the pulley, splice a belt and go.
MORE LINE SHAFT RUNNING MACINES
The 6″ Houston Molder and the No 2 Rip Saw are now both on the line shaft. The details are in the posts for those machines.
