Metal Workshop Expansion 2026

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

Terminology

We have decided to split the workshop into 2 parts:

Machining : Lathe, Mill, CNC, Pillar Drill etc.

Fabriation : Welding, Grinding

Immediate tasks

Clean Area 95% Done

Update Floor Plan

Identify if remaining objects left behind from wood shop move are junk or treasure

     Dispose of the above if junk
     Relocate to other areas
     Find a home for it in the area

Paint walls

     Remove raw plugs etc. Machine shop done.
     Fill screw holes. Machine shop Done.
     Get paint and brushes. Done
     Paint them. As of 2026-03-29: Machine shop done
     

Paint floor

     Prepare floor. Remove tape etc. Machine shop done.
     Get paint and brushes. 2.5L of floor paint in workshop. Machine shop done.
     Paint machine shop. Suggest we first paint the area where the CNC will go, and then move the CNC. Done.
     Paint second half.
     

Move equipment to final positions.

     Move CNC. 2026-03-29: moved but needs repositioning.
     Move Lathe. We plan to do this next, once we have worked out a good way to move it.
     Move Small items

Petrol-powered tool maintenance No? Yes Discussed 13-01-2026 Strictly no fuel allowed inside the bulding

Possible New Equipment

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

Decisions

Questions

  1. Grinding. There is a wide range of use-cases to consider. Some may have stricter contraints (ventilation, hotworks area) than others.
    • Hand tools. Under consideration.
    • Tool sharpening. TBD
    • 'Sword-making'. Hotworks area only.
  2. Extraction for Lathe and (proposed) Mill. Intensive operations using cutting oil or coolant may create a lot of fumes. Do we need to plan for an extraction system?
    • Assume not for now. We want to keep open the possibility of short production runs which might require the use of a coolant system.
  3. 3-phase electrical supply. Second-hand machines using 3-phase are much more common and much cheaper than those that run on single-phase. We have 3-phase to the building and there appears to be nothing stopping us making it available in the metal shop. Machines that might require 3-phase:
    • Lathe (currently has its own 3-phase converter)
    • Mill
    • Pillar Drill

Floorplan

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.
    • Rejected for welding. Still a possibility for some types of grinding.
