Working estimates for venue space requirements are 4200-4500sqft. A fair bit more than the pure guesstimates.

This means the budget estimates for rent are about £1000 too low.

The cheaper properties are warehouse units as it is, so one option is to buy a used mezzanine floor and put some areas above others. It would increase setup cost & operating complexity, but decrease long-term running costs.

I'm hopeful that worst-case it would just mean we couldn't sell any materials for all of the Sunday opening hours. I think this is business-advisor territory.

Current workshop area tally is 205.82m^2. The working clearances for the woodwork room really pushed it up. Still does not include the general workshop, digital & design, finishing/drying and some sundries (like space taken up by walls).

If it comes in under 280m^2 it avoids Sunday trading laws for sales. A small shop is one that measures up to and including 280 square metres.

I don't know if this covers access-services. I don't think gyms, for example, are held to Sunday opening hours.

Tool library estimate complete. Approximately £2465.

Allocating £3500 of the budget to loose tools should allow for rebalancing & unexpected additions.

Tallying up the estimates for hand tools. Currently at £762. That's probably going to double, and I'll want to double that total to account for ad-hoc adjustments after opening.

@alexeigynaix Thankyou, there are a lot of holes in the area of textiles (no pun intended).

Important question to all crafty folk.

I'm drawing up the list of kits and equipment Workbench Alpha will need in the tool library so I can estimate the costs for the business loan.

What I need is you to tell me the tools you use in order of how often you use them, and if you always use some together. That's it. I just need additional perspectives.

Please don't read other peoples replies at first. I don't want you leaving things out just because someone else has mentioned them already.

@mlg Also thanks for that reminder. Equipment tests needs to include infrastructure, not just tools.

The intention is to have environmentally segregated rooms. Woodwork doesn't want to share with grease & metal chips. Textiles doesn't want to share with sawdust & splinters, etc.

The access control system should be able to monitor emergency stops on individual machines, and remotely interlock machines that share a workspace.

@mlg Additionally each room will have equipment with differing power draws. I'd expect metalwork to need something high rated when welders may be in use. Likewise a machineshop with lathes & mills.

Simply having the switchgear customised with a single part is very appealing.

Regarding cooling, I was looking at the Hylec DED50099 cabinet. I would have thought fixing the relay/contactor directly to the shell would provide enough passive cooling? Duty cycle should be at max 17hrs.

@mlg Possibly overkill, but if the prices are right there's no harm in it.

Each machine will have it's own large-headed knee/punch emergency stop. The envisioned use case of the whole room one is someone outside the room hears the scream and can hit it on the way to help, saving a few seconds from outside the danger area. There'll also be a rotary isolator and indicator lamps.

The safety features need to be on par with a teaching workshop. Can't expect skilled users.

@mlg Presently it looks like most of the tools will be single-phase. But there may be some 3-phase equipment later on.

I would think a relay based system would allow both types to be killed from a single button. That would be a nice bonus.

Wouldn't having a NO relay be safer? Break the power to the coil to disconnect? Or is the response more reliable powering it?

I haven't personally had any experience with high current relays being engaged for extended periods. What issues are there?

Anyone got experience in industrial power switching? Looking for how to best put a whole room of tools on an emergency stop. Single switches only seem to be rated for 10A.

EG; a darkroom is a commonly requested feature of a makerspace, but it only used very occasionally by a small proportion of the membership. Allowing a photography group to rent out a room off the main workshop would add the feature at no risk of wasting resources on something little used.

Another might be high-vacuum equipment. Surface science & space research. It's a specialist interest and may only been needed for an 18month project.

Hmm. Further to the thought about sub-letting reserved space until it's required.

While some things that go into that space may be permanent additions or changes, it seems likely that a lot would also only be mid-long term or of niche appeal. In that case they'd be functionally identical to sub-lets for user groups or members.

So maybe it would be better not to make sub-lets a temporary addition, but a permanent feature to accommodate mid-long specialist workshops.

It seems a lot of emergency stop switches have both NO and NC connections.

If I add an opto-isolator to the NO terminal the access control system would be able to detect emergency stop states in addition to power monitoring.

One issue with creating a physical space is you know eventually you will need to expand in currently unforeseen ways. So ideally you need to obtain a larger space than you immediately need, or be prepared to move multiple times.

To create a presence, the longer you stay at one location the better. But reserved space is either wasted or will fill with junk.

Another option has occurred though. If access permits, partition and sub-let the reserved space. Storage? Co-working space/offices maybe?

@cscottmills If it has to take any strain at all, you're likely better off looking at replacement.

If that's off the table, adhesives aren't likely to be of much help with such a small area to glue. You might get a few months out of a repair using a nice fillet of JB weld on the inside. Presuming there's enough clearance.

Else I'd suggest grinding back the stub and replacing the broken off part with piece of steel flat, bolted on with tapped holes. It'd be a fiddly job at that scale though.

Oh, a knitting machine fell into my lap last week. It seems intact but I'll have to get someone to look at it.

Seems like it might be of use to the workshop if it's serviceable.
