Most woodworkers that come to our plant enjoy a tour through our knife grinding room when we are able to do it. Obviously, because of time constraints we can’t always give a tour. However, I thought that some of you Lumberjocks might like to see where we grind our molder knives and how we store our knives and templates. The knife grinding room is situated between two rooms. The two adjacent rooms contain shelves with molding samples and the templates. In each cubby hole we have the templates, a sample piece of molding, and the knives. Sometimes it takes as many as 4 templates and 4 knives to make a moulding because we have to mold all the way around the profile using 4 molder heads. These would all generally be stored in the same cubby hole with the sample.


This is one corner of the larger knife storage room. I think that this room contains the knives for at least 1700 profiles. We probably grind 5 to 10 new profiles each week.


This is another corner of the same room. The funny looking fixture on the work table is the jig that we use to set the knifes for our finger joining heads before being ground.


This is a view from the other side of the work table. The door on the right is the entrance to the grinding room.


This is a closeup of some of the cubby holes.


This is a view of the knife grinding room as seen from the previous door that I mentioned. The profile grinder is on the left and the straight knife grinder is on the right. The smaller storage room is through the door straight ahead.


This is a view of the profile grinder from the smaller storage room. The metal rack on the left contains some of our molding heads. Our largest molder will mold a profile that is 11-3/4 inches wide. It’s spindles are 2-1/8 inches in diameter so some of these heads are quite large and heavy. The knife grinding man and the molder setup man have to be stong enough to do this work because only one man can place these on the machinery.

Although I am no longer able to do this work, I was the knife grinding man, setup man, and maintenance man for nine years. It’s been 10 years since I ground the knives. Now I’m a helluvawreck. :-)


This is a closer view of the profile grinder. The work table is where the knife grinding man loads the knives in the molder heads. The two arbors on the table are the arbors that the knife grinding man puts the heads on. These locate the head on the grinder so that everything is parallel and square.


This is a view from the profile grinder towards the straight knife grinder. The straight knife grinder is automatic so while the knife grinder is grinding a profile a head the straight knives can be ground automatically. The knife grinder could not possibly get his job done here without the straight knife grinder. The knife grinder has a full time job. We have 5 Weinig molders and need to keep them running. Our finger joining heads are also ground on the straight knife grinder with a slightly different setup.


This is the other corner of the smaller storage room. BTW, with 2000 profiles, the knife grinding man must also be quite familiar with the different moldings and able to keep the shelves straight lest he create havoc.
He is also generally the type of person who likes to work all by himself in his own little world – sort of like a watchmaker at a jewelry store.

That’s about it
