    Default 12m x 6m Colorbond Shed - Storage Shed to Workshop

    Hi all,

    Finally getting around to posting this... Any advice/input is greatly appreciated.

    Shed Details: 12m x 6m x 2.7m with 15° roof pitch (ridge height is 3.5m). Portal frame with 2 roller doors and one window. 2 x whirlybirds
    12x-6-Shed-V3 - Copy.png
    Roof insulation: Kingspan Air-Cell Insulshed 50
    Wall insulation: Reflecta-Guard by Green Insulation
    Wall lining: 15mm structural plywood
    Floor coating: Hychem Epoxy Flooring - Off white pigment
    Electrical: 3 phase (need to confirm whether 32A is sufficient)
    Lighting: LED fluros (tbc)
    Background: Unfortunately, the shed was originally built for storage with the possibility of a small workshop. Shed was located hard up against boundary fence lines, with large water tank and chook run adjacent to north and east walls.
    Injury at work changed things, so now the plan is to turn the entire shed into a workshop, focusing on smaller pieces with view to trial a shared work environment.

    Had I built the shed specifically for workshop purposes, I would have included a pad for the DC on the south wall and increased the height of the shed walls to allow for a mezzanine. I would have also removed the whirlybirds and swapped the roller doors for something more airtight and soundproof.

    Obligatory shed pics attached...

    Default Machinery options

    I would prefer 3 phase machinery (where possible).

    Probable:

    • DC: Clearvue CV1800 (thinking about the CVMax to allow for multiple users)
    • Ducting: 150mm PVC
    • Bandsaw: Undecided, but would prefer 400mm cutting height
    • Planer / Thicknesser Combo: Undecided, but would prefer 400mm surface/thicknessing planing width
    • Panel Saw: Undecided, but would prefer having the ability to cut a standard sheet of board (2400x1200)
    • Drum Sander: Supermax 19-38 (single phase only)
    • CNC: HIGH-Z S-1000/T by CNC-Step
    • Air Compressor: Undecided
    • Drill Press: Undecided
    • AC: Undecided

    Possible:

    • Bandsaw: Laguna 18 BX (single phase only)
    • Bandsaw: Hammer N4400 (cutting height is only 310mm)
    • Planer / Thicknesser Combo: Woodman Planer/Thicknesser with Helical Cutter Block
    • Pro - PT410HH (single phase only)
    • Planer / Thicknesser Combo: Hammer A3 41 (need to check pricing)
    • Planer / Thicknesser Combo: Minimax fs 41c (need to check pricing)
    • Drum Sander: Carbatec 635mm Wide Drum Sander (single phase only)

    Combo option (replaces planer/thicknesser combo + panel saw):

    • Minimax Cu300 Classic combination machine (surface/thicknessing planing width only 300mm)
    • Hammer C3 31 perform (surface/thicknessing planing width only 306mm to 310mm, need to check pricing)

    Good size shed.

    If your compressor is a decent size and has any chance of triggering while running your DC and 2 other machines under load you will need more than 32A.

    If you intend to run more than one machine then you may need a larger trunk line for your DC.

    Looking good!

    If the funds aren't too much of a problem then try to avoid combination machines. You certainly have the space for single machines. Having to de-set the jointer to go to thicky can be a bit painful (I have an A3 31). I imagine that becomes even more painful when a saw is added into the combo. It also means you can have a much wider thicky which is useful. A wide jointer (like the A3 41) would be a little hard to control without mechanised infeed I suspect (and the A3 41 must be up around $10k now).

    Yeah, the sparky gave me a rough quote based on what he thought I might need, but I hadn't worked out what machinery I'd be using, so I'll need to revisit that.

    Agreed. If I go with the CVMax (and therefore multiple users), I'll be looking at 200mm/225mm... not looking forward to the additional cost though!

    Thanks FF!

    Funds are always a problem...
    I was thinking it would be better to have a good brand of combo machine than lesser quality single machines.

    To be honest, my jointer needs are max 250mm, but would need the larger thicky. I've never used a combo before, so it's good hear about your experience. They make it look so easy in the promo videos...

    Once you get used to a combo, they are easy enough to live with. A sliding drop saw is a handy thing and when a combo is tied up doing other things the drop saw does the business.
    If you do decide to go down the combo route, get one with a scriber and a table long enough for sheets.

    Yeah, I have the Makita LS1216. Great saw, but I wish I had bought the Bosch equivalent due to the space saving abilities.

    And yeah, panel saw will have a minimum 2500mm sliding table + scribe. I've been speaking to a few machine companies and the biggest turnoff is the wait time... Some are talking about delivery in the 4th quarter of the year!
    Might have to revisit my machinery list...

    A good used machine may be the way to go. I upgraded my old Robland machine for an unused secondhand one and saved $3000.

    Hi Junkie
    Suggest you buy a CVmax and run it at 50hz with 150mm pipe. Much quieter than a CV1800 at 60Hz. Unfortunately I made the mistake of buying the CV1800

    Cheers for that Ron!

    Didn't think there would be that much noise difference between the 2, but that pushes me into the CVMax camp as it allows for expansion/multi users...

    So I gave the sparky a list of machinery that would be most likely be run simultaneously (as well as lights; fans & GPO's), and his reply was: "it might be worth running 10mm mains so that you have a 40A 3 phase supply".
    The list included:
    • Panel Saw - 6hp (3ph)
    • Dust Extractor - 4hp (3ph)
    • Air Compressor (intermittent) - 5.5hp (3ph)
    • Drum Sander - 3hp (1ph)
    • Drop Saw - 1650W (continuous rating input)


    Will 40A cover it?

    The run from the house board will be less than 20m.

    Only the compressor and the DC will draw close to their full current load on a continuous basis while they are running. Depending on what is being worked he other machines may only occasionally reach their nominal max current.

    Machines like chops saw are very intermittent nominal max current drawers and even panel saws are semi intermittent drawers of nominal max current.

    The most likely nominal max current drain you will have at any one time is the DC, the panel saw running under nominal full load, plus if the compressor decides to recharge when you are in the middle of something. I make it that these will draw ~28A so 40 A will easily cope with that.

    With all machines running under nominal max current land they won't reach 40A.

    The reason I keep using the term "nominal" max current is because that is what the sparkies use for load ratings.

    With machines like saws and drummer sanders it is possible to draw currents above their "nominal" max load but this is usually for very short periods which may be accommodated by the breaker AND the chances of the machines all doing that at the same time is very small.

    Thank you BobL, your reply is much appreciated!

    I didn't want the supply to be under estimated, but at the same time, don't want to overcapitalise unnecessarily...

    I'll give the sparky the go ahead

    If you use a CV1800 you really need to run it at 60Hz to get its rated performance. A CV Max has a larger impeller and achieves roughly the same airflow at 50hz. My CV1800 is quite a bit louder at 60Hz than 50hz ( Even though I have 3Phase I use a VFD to get 60Hz). I know the noise difference between the CV1800 and CVmax will not be quite the same as air noise is dependant on air speed. If you have 3Phase available the extra for the CVmax is offset a little by not requiring a VFD with the CVmax in a 1 man shop. Since the airflow is similar with a CVmax at 50Hz you can still use 150mm ducting
    Cheers
    Ron
