Is this the full-height rack ?

nope it is not a full height rack

[arthur tinsley]

How big is it and where are you planning to store it whilst you aren’t there?

After 5 projects with no comment since our move and my first at ex2, I am delighted at all the interest in my project, I am glad we are alive. 

The location has not moved, it's still in the electronic and metal work area and will be in various spaces in these areas as it progresses.

I don't have a final size, but the base will be similar to a 19-inch rack square, probably going  12 u high. 

The objective is to package individual bits of kit into a modular package. 

[Adrian Godwin]

Unfortunately a rack-sized object is pretty awkward in the current space. There aren't the large empty floor areas we previously enjoyed. 

Parking it by the electronics bench would be very restrictive. I suspect it will end up by the CNC machines or in the woodwork area. This may not matter if the CNC machines remain out of operation until your project is completed but that's up to their maintainers.

Will the base unit have wheels from day 1 ?

I agree with you that we don't enjoy the large empty floor areas we previously enjoyed.,  Any idea when you are removing your environmental oven? I've been told a few times it's departure is imminent, it is currently taking up a full pallet of floor space up.

There is enough space under the electronics counter or ones next to it for what I am doing, and yes, it will have wheels from day one, the space by the CNC machines could be another appropriate space I had not seen that as a "vacancy". There was some work going on to the CNC the other evening.

[arthur tinsley]

Neither the electronics bay nor the metal shop are sensible storage locations for something of this size, however if it’s on casters then I suggest underneath the table for the laser cutter PC is a much better option.

It's not exactly mine - it was a donation long ago, when it was somewhat useful.

I'm not involved with its removal.

[deanforbes]

The laser cutter table has cross struts/solid shelf under it and is lower than a work bench from what I recall, (am I wrong) it is also partially blocked by the environmental oven, It a very awkward spot, @Adrian, Interesting that I was told that they were waiting for you to remove it. They aren't easy to dispose of, if we are insistent that my project should go in that corner and I need to get rid of it I am sure I can make a plan, the last one I disposed of I chopped up.

 

Under the electronics benches has more than enough real estate in terms of depth, width, and height. Also it will live under an electronics bench ultimately. The LHS electronics bench/the benches have a wide variety of stuff stored under them, including stackable storage crates that are stackable, some of which are not stacked. I am at a loss as to why that's not sensible,

Something that is made up of metal components will have elements that are smaller that should be worked at times in the metal shop I don't get why that isn’t sensible either. For clarity, "the base will be similar to a 19-inch rack square" for those of you that don't do inches or don’t work in the electrical or  IT domain, that's just under 50cm square, (the current foot print _ I am rebuilding and reconfiguring a power supply) for contrast, a standard pallet is about 120 cm * 100cm so my project has a foot print of roughly a of the size quarter of the size of a pallet. A pallet space is the space taken up obsolete and unused environmental oven.

 

I wonder why I am beginning to feel like Alexei Navalny.

[deanforbes]

lower than a work bench =  lower than a electronics work bench 

[arthur tinsley]

In no particular order:

- The laser table has no shelf etc under it and I would be stunned if it didn’t have 600mm clearance (12u + even 75mm casters will easily clear 600). 

- The oven isn’t in the way. Just at all. It’s also not on a euro pallet.

- Adrian did kindly donate the oven years ago, but it is now ours. Whomever told you he was responsible for removing it is making things up. We will deal with it when it becomes necessary, which it currently isn’t.

- I have no issue with you working on it in either the metal shop or the electronics bay obviously. 

- The metal shop does NOT have enough space for it to be stored there without being an inconvenience. 

- Whilst there probably is space under the electronics bench if you rearrange things, I’ve suggested a currently (to the best of my knowledge) free and clear location that won’t be in anyone’s way which is much more appropriate

"if we are insistent that my project should go in that corner and I need to get rid of it I am sure I can make a plan"

I hope you were not suggesting that you might unilaterally decide to dispose of hackspace or member property without the express permission of the trustees?

Just to be clear, that would be unacceptable.

Jonathan

My apologies Dean, it's come to my attention that the tables have in fact been moved around which I was unaware of so under the laser PC is no longer viable. Under the Kiosk however should still be clear enough to get a rack in and out (I have done so previously). Please feel free to use that space. Despite the fact that I now have the rack which will permanently live there, I'm unlikely to be able to get to site and fit it in the near future due to my work schedule.

When the environment oven was at Wembley, quite a few people asked for it to be removed or were annoyed by it for whatever reason. I was agnostic as it wasn’t in the way and we had more than enough space in my opinion, (Ironically I was one of the very few people that had used it) I did however agree that it was not used and just sitting there so should probably go, It had been carted around and stored by the Hackspace from Wembley too.

 
I spoke to Adrian, who said if we wanted to dump he would like to recover it but did not have suitable transport at the time, when he did have suitable transport, the move was imminent, and he said he would deal with it then, which at the time was sensible. When the move happened I wasn’t around. I trust we won't have the usual bout of selective amnesia

 
Given the prior conversations when I arrived at EX2 I asked what it was still doing around the response was that Adrian did not currently have space but it would be moving soon (that was 2-3 months ago off the top of my head) I am a man of my word and take others at the word it is pity that in some environments that not good enough – thank goodness it not life and death issues

I offered to help dispose of it as a solution not stating what I was going to do – it is fairly clear from the context etc. I would not remove any valued hackspace assets, especially after the coke can bits furore and the new regime.

Back to the topic at hand
The table does have struts, I can attach a photo, which I have just been in to take, which will illustrate this quite clearly
If the original locations are untenable, I feel now that the gap in front of the CNC is the best place after another physical check – the objectors and Johnathan, as he was looking at the CNC, are you OK with this

[deanforbes]

Clearly I am slow at typing - just posted a message - and your was there - thank you for your apology - we all make mistakes 

I had not looked at that location, I will when I am in, if it does not work is in front of the CNC a suitable alternative   I would like to avoid wrestling infrastruture and equipment out the way when I want access

Status changed to Approved with the reason 'To be stored under the Kiosk, with in front of the CNC as a backup if needed' by Arthur Tinsley

That may well have been the case at the time. However nobody has discussed it with me since the last move and although I had heard it was likely to be scrapped I'm no longer able to use it and don't have any interest in recovering parts from it so I've raised no objections.
