Usable

The thicknesser is not feeding the material. We will have to adjust the pressure rollers tension.

This machine requires induction to use.

In order to get inducted on this machine, you need to go to the following Eventbrite event and book a place for yourself on one of the available dates.

Planer/Thicknesser inductions

After that, you just need to come that day and take the induction. Please pay attention to the description of the event because there's a couple of things that you need to comply with. Most importantly, be on time and bring your own mandatory PPE.

The cause has a commitment to giving at least one induction per week on one of the machines that require induction. The way we organize all of this is by having fortnightly polls on the forum. By doing this we can check the actual demand and deliver a solution.

When we create dates they will be announced through discord (woodchop channel) and the messages will be pinned.

In summary:

  1. Check this link to see if you can book an induction: Planer/Thicknesser inductions.
  2. Check the forum to see if there's a poll open to organize the following inductions and vote accordingly.Woodworking forum
  3. Talk to the cause leader about it or start a conversation on discord.
  4. Check the helpdesk channel on discord.

PLACEHOLDER: This is where you can document the usage practices for the machine generally. If this section gets very long, then it should be part of a canvas course for induction. Don't document maintenance procedures here, please do that below in the maintenance section. Delete this line.

Recommended We recommend hearing protection.
Recommended Please wear goggles or a face shield
Recommended We recommend the use of a respirator
Required Enclosed shoes are required, no open sandals, thongs etc
Warning Gloves are PPE against your material (splinters, resin etc) but are hazardous around the saw. Please carefully evaluate your use of gloves

Thicknesser / Planer

We have a Hammer A3-31, located in the woodshop. You need to be inducted on this machine to operate it.

Manual

Thicknesser / Planer adjustments

Blade height is set by raising or lowering the outfeed table. The blade position is set. The Blade should be _slightly_ higher than the outfeed to give a straight cut. If the blade is too low joints will be convex, too high and joints will be concave or stepped. We're looking for the goldilocks height. The Blade also needs to be level to the outfeed table. The outfeed table is the REFERENCE FACE - when planing one should aim to have the freshly cut face resting on this table.

Height and level (left-to-right as one looks at the machine) of both tables is set by a pair of eccentric rods, joined by a linkage so that they turn together. These rods move the hinge and a plate at the front of the table relative to the table surface. As long as the linkage is working, the two will move in sync and the table will move without tilting left-right. To adjust left-right tilt, disconnect the linkage and rotate the bars individually. a331_bars2.jpg2019-01-24_17.00.56.jpg Once the bars are loosened, they can be moved with the help of a lever (a screwdriver in this case). In the first photo we can see the locking bolt on the linkage in place. This has been removed in the second photo.

The manual only hints at how to do this, but this seems to work..

a331_power.jpg1. Disconnect the power!!

2. Did you disconnect the power? Check.

3. Rotate the guard arm out of the way (loosen the cam where the arm meets the machine and rotate).

a331_covers.jpg4. Remove the covers (front and back) with a 5mm(?) allen key…

2019-01-24_17.00.56.jpg.. to reveal the linkage between the ecentric rods and the locking bolt.

a331_locking.jpg4. Remove the locking bolt (7mm AF).

a331_loosen.jpg5. The manual suggests loosening the 17mm nuts immediately behind the linkage to allow the rods to rotate. There is very little room behind the linkage so I suggest you loosen the nuts at the back of the hinge instead/as well..

a331_back.jpg

6. With a bit of luck, and perhaps some gentle percussive persuasion, you should be able to rotate the eccentric rods in unison.

7. Rotate the left hand bar with a lever (screwdriver in this case). Clockwise raises the table.

8. Close the table and cinch the hand clamp.

9. Check blade height. Use a flat stick, resting on the outfeed table. The blade should just catch the stick. Check that the catch is the same at each end of the blade, indicating that the table is level to the blade.

a331_height.jpg10. If the table is _not_ level to the blade, adjust the bolts at the front of the machine. Mark the top of the bolts and rotate each by the same amount.

11. If the blade is not at the correct height, go back to 7. Rinse and repeat.

12. Once happy with level and height, re-tighten the bolts (front and back) holding the rods.

a331_locking.jpg13. re-install the locking bolt on the linkage. If the slot for the bolt and the threaded hole no longer overlap, loosen the hex-head bolts cinching the linkage to both rods and move the linkage (the rods NOT moving) putting the threaded hole in the middle of the slot. I had to do this the first time, but hopefully it's now in a good place.

14. If the table has been moved, you may find that the hand clamp no longer cinches - move the plate into which this locks up or down by loosening the bolt holding it to the frame.

15. Remove all tools from the machine, replace the guard. Plug the power back in.

16. Run a wide plank through at 1mm or so. Give it a couple of passes. Check for flatness.

17. Check that the fence is still at 90 degrees to the table/blade.

Cut depth is set by raising or lowering the in-feed table using the handle at the front of the machine. This handle, bought up to the stopper, should give zero-height difference between the in- and out-feed tables.

The height and tilt of this table is again set by eccentric rollers. These are easier to adjust than the out-feed pair since they move day-to-day.

Remove the red cover from the front adjustment mechanism. We will use this mechanism to rotate the rods together or individually to adjust height and tilt respectively.

2019-02-19_21.19.54.jpg Need more photos…

Two allan keys (6-7mm?) hold the arms of the mechanism to the rods. We will use these to rotate the rods.

1. Get the left-hand edge as close to the same height as the out-feed table as possible (should be pretty close anyway). If it is below the out-feed height even when the mechanism is against the end stop loosen both allan keys, adjust the knob down, re-tighten and retry.

2. Once the left hand edge of the table is at height, loosen the left-hand allan key. This will stop the left-hand eccentric rod from turning.

3. Use the handle to rotate the right-hand rod, lifting the right-hand edge of the table up/down.

4. Rinse and repeat until you have the in-feed table co-planar to the out-feed.

5. Loosen both allan screws and raise the handle until the mechanism hits the end-stop (0mm). Tighten the all screws. The table should now move up and down, remaining parallel to the out-feed table.
