To use a drill press, you'll need to mount a drill bit that suits your workpiece and securely fasten it with the chuck key.

Safety

• read the manual!
• get a personal introduction by one of the tutors!
• wear personal protection, but never operate the drill press with gloves on!
• don't drill materials with harmful dust!
• make sure there is nobody nearby who might be surprised by a piece of shrapnel flying their way!
• use a machine vise for small workpieces!
• never use a machine vise on top of a wooden board or two wooden boards at the same time (tower rule)!

Fastening Options

a lever clamp can be used for some workpieces such as this door handle shaft

• we should get one or two of these drill press locking clamps if they are available around here
• additional tables to mount on the simple "standard" one are probably worth the effort
  • inspiration: Stephan Pöhnlein on YouTube

Jigs

Some ideas what we should make for a more efficient/safe use of a drill press:

• V-block for drilling into round or angled things
• vertical clamp (very simple, basically to board with a hinge at one end)

Blacksheep kindly donated a Scheppach DP 16 SL drill press in August 2019.
From a technical point of view, it offers the following:

• Drill mount: 3 - 16 mm
• Speed: 510 800 - 2430 rpm

Drill Speeds

When changing the belt position, unlock the the motor hinge with the screw on the right side. Then move the belt on the pulley that reduces the diameter and afterwards change the belt position on the second pulley (similar to changing the chain on a bike). When the belt is in its final position, it should be level (waagerecht) and have enough slack so the motor can be pushed back and re-locked with the screw.
The slowest speed is currently not available due to a broken pulley!

Depth Stop

The original depth stop collar broke relatively soon, so Patrick designed a 3D printable replacement part.

Einhell TB 13/5 ED

MachineInfoBox Einhell TB 13/5 ED
Access Requirements:	Drill Introduction
Manual:	very similar to "Güde GTB 13/5"
Tutors:	Lukas NitramLegov Pakue Lmnl99 Johannes Luzian Keno Jakob

We got this machine when it was pretty old already so Patrick took it apart, cleaned and painted it. Something in the pulleys still isn't centered which causes slight vibration in the machine. It isn't much of an issue as the shaft is quite rigid and runs true.

The drill bits can sometimes be a little off center as the chuck is not that great - just quickly check before drilling. It often helps to twist the bit back and forth with one hand while closing the chuck with the other.

Shortcomings/Upgrade Potential

the depth stop of the Einhell drill press is made of a flexible material, reducing its precision - while this can often be ignored, it is important to remember for fine work

Until there is money left over for a newer/fancier drill press, we can collect desirable features here:

• more stable depth stop (see photo)
• electronic speed control instead of manual change of belts
• larger "throat size" (distance from the drill bit to the stand)
• safety: clear chuck guard (probably rather common nowadays)
• anything else?
