Now the woodshop move is complete, we can start work on expanding the metal workshop. We had some useful initial discussion here: https://bristolhackspace.discourse.group/t/metal-workshop-expansion-planning/3925 and the intent is to capture issues and decisions in this wiki

1. Fill screw holes
2. Paint floor
3. Paint walls
4. Identify if remaining objects left behind from woodshop move are junk or treasure
5. Dispose of the above if junk

• Fire sensors: The metalshop currently has two, and if we keep the strip curtain, it needs to stay somewhere between these sensors. This does give us a little bit of play for moving the strip curtain up or down the room if desired.
• Hotworks only insured for welding and griding.
• Welding only within an arc-shielded environment.
• Welding and grinding only within a non-flammable environment. Update: Requirements for grinding need to be clarified. Not as strict as for welding.
• Welding needs ventilation so either next to the roller shutter or fit the large welding extractor we have in storage.
  • Moving the welding away from the roller shutter would require negotiation with the landlord.
• Old woodshop has the mezzanine supports which have Intumescent paint. Hotworks might damage the paint?
• The welder needs a 16A supply which we have by the shutter (plus another in the old woodshop which was installed for the jointer).
• Wall behind the current wooden metalshop bench has a removable lower panel for access to the laser room.
• Duncan prefers to keep the door into his half of the building accessible.
• Lathe positioned with access to feet, 30cm to the right to allow for maintenance, 305-50cm to the left to allow for long workpieces.

• Welding in an area where there is no chance anyone will accidentally enter. The current layout is not ideal.
• Grinding should be available even when welding is being done
• Lathe in a position where workpieces that protrude out of the left side will not cause a hazzard
• Group machines that are commonly used together
• Separate dirty and/or noisy machines from cleaner/quieter machines
• Workbenches in the centre of the room (following the woodshop layout)

All new equipment needs a proposal. Some of the suggestions may not be practicable.

• Milling machine e.g. 626 Turret Mill - Metalworking Milling Machine
• Pillar drill + float-lock vise
• Sheet metal bender
• Induction heater and/or Electric kiln. Rejected 13-01-2026 due to safety concerns.
• Induction forge + tempering setup. Rejected 13-01-2026 due to safety concerns.
• Plasma cutter e.g. ArcDroid CNC plasma cutter. Discussed 13-01-2026. Need advice.
• Water cutter. Unlikely to be feasible.
• Heavy-duty metal fabrication workbench.
• Standing belt sander to use with metal

• The metal CNC will be in the metalshop. Probably RHS of old woodshop.
• We will move the lathe into the old woodshop. Probably against LHS wall (looking in from the front), just inside the old woodshop.
• The welding area will stay where it is. (13-01-2026)
• Plan is to split the workshop into 3 areas: Engineering workshop (old woodshop) for 'clean' operations, welding & grinding area for the most dirty, and the remaining area for those in-between.
• The existing curtain to be retained but possibly moved towards the front of the building.

Several options. So far the only complete proposal is: https://bristolhackspace.discourse.group/t/metal-workshop-expansion-planning/3925/37

Other possibilities:

1. Move the welding area to the far end of the old woodshop, making use of the extractor. https://bristolhackspace.discourse.group/t/metal-workshop-expansion-planning/3925/53
