Safety at a Glance

Required:

  • Safety Glasses
  • Push Blocks
  • Hearing Protection
  • an experienced jointer operator (if this is not you, you must get someone to train you!)
  • Active Dust extraction

Optional (but recommended):

  • Face Shield

Prohibited:

  • Gloves (NEVER use gloves near rotating machinery!)

Safe Operation Details

Description:

TBD

Start With A Risk Assessment To Ensure A Safe Work Area:

  1. A two foot perimeter around the jointer should be kept clear of people, debris and sawdust that impair traction or footing to avoid slips and falls.
  2. Infeeds and Outfeeds should have enough room for entire stock to travel
  3. Safety glasses with side shields or a face shield must be worn. Hearing protection must be worn.
  4. Indicate to all others that loud noise will be made
  5. Remove loose fitting clothing, jewelry, and tie back long hair.
  6. Give the work your undivided attention.
  7. Do not wear gloves or anything that would allow a hand, fingers or clothing to be wrapped around the cutting blade.

Operational Safety Rules:

  1. Approach your work at VHS and on the jointer with a safe attitude!
  2. Make all jointer adjustments with the power shut off.
  3. Keep all guards and covers on the machine when it is on and running.

Maintenance

Blade Replacement

February 17, 2019 By: Logan Buchy

The jointer blades were replaced with new ones (Powertec 148030). The following procedure was used to align them.

Tools: * 3mm hex wrench * Ruler

Step 1. Remove the safety guard On the Delta 37-190C usually one can just pull the safety guard right out of its holder. Ours has had the shaft of the guard modified to have a stopper bolt installed to prevent the guard from accidentally being removed. Use the hex wrench to remove this bolt. The whole safety guard should slide right out.

Step 2: Move fence all the way to the furthest back position. Position the infeed table so that it is isoplanar with the outfeed table, a ruler will help with this.

Step 3: Clean out the slot where the jointer blades sit. There is likely to be pitch and sawdust caught in there.

Step 4: Install the jointer blade such that the bevel is on top of the drum. Position the knife hold mechnism (has 4 jack screws) and loosen the jack screws so that the knife and mechanism rest in the drum carriage but not tightly. You should be able to shift the knife and mechanism back and forth with your finger.

Step 5: Measure the straight edge of a piece of plywood with a 1/4“ marking. Position it so that the marking is against the outfeed table's inner edge.

Step 6: With the fence all the way at the back, rotate the drum in the normal direction of travel. The blade should slightly catch the plywood and move it forward. The intention here is to make it move forward only 1/4”. If the plywood does not catch, raise the blade using a hex key on the riser bolt. I found it easiest to get it close to the point where it will catch, then turn the bolt very slightly (1/8 of a turn or so). Keep going until the plywood moves 1/4“. Repeat with the fence all the way at the front.

Once you are happy with where it is, tighten the jack screws. Check again with the plywood to make sure the blade didn't shift while you tightened (it usually does, it can help to hold the blade down with the ends of your fingers on the bevel).

Step 7: Repeat with the other 2 knives.

Step 8: Check again that all knives are still in the correct position.
