Record Power - Coronet Herald

[Toby Williams]

Hi,

Record Power have been in contact about the Coronet and have offered us a material discount to keep the lathe (or take it away). I have spoken to Andrew and the directors, there is sufficient cash to buy the Coronet (if I spread the cost out for the hackspace over a couple of months).

 

I believe that we should buy the Coronet, for the following reasons:

1. It's a good price, we aren't likely to get this kind of deal on this kind of lathe again.
2. It's an awesome tool, great stability between the bed and head (I am certain the thing will be even more stable one properly fixed down - more on that below).
3. Quiet and compact (with the bed extension, it has the same distance between centers but with a small overall length) and the head can be slid up the bed to reduce the size further when not in use.

I got some comments from people at the space that aren't frequenters of the forum and are regular wood turners, who supported Coronet.

Why not get an even larger lathe?

• The hackspace doesn't have the money at the moment to buy a large lathe.
• We aren't being offered a discount on any larger lathes (I asked about the Maxi, there will be no discounts as they've sold every single one of those they can make)

Why get this lathe at all?

• I've included some pictures below of a recent project, this project wouldn't have been achievable on the larger perform. I got a lot of nice feedback from people indicating that this is a nice for us to be able to turn.

It isn't that stable/it wobbles!

• Lathes wobble/vibrate in two ways, one is between the head and the bed and the other is between the bed and the outside world. The coronet is very stable between the head and bed but isn't fixed down. Steve and I have discussed welding up a workbench to hold the Coronet and other tools, the weight of a steel frame and the other tools/storage would eliminate any wobbles/move in all but the most extreme cases.

 

Many thanks

Toby

I support the purchase of the Coronet. While a larger unit would satisfy some latent macho longings to turn stupidly large bits of tree into wood chips ( and I preferred the Jet to the Maxi because it is macho-ier ) the Coronet is a very nice compact machine and undoubtedly best option.

Not being a wood-turner myself I've no strong opinion on the choice of
lathe we should have but I can certainly appreciate that we've been
depleting the funds somewhat recently and there's a few more items still
to come so the prospect of a discount lathe certainly seems sensible!

Toby and I have talked about making a new stand for it to make it stable
for larger turning jobs and I'm confident that I can design and weld up
something suitably strong and heavy while still being on wheels so we
can rearrange the space. Likely this job can be combined with the making
of the new metalworking table which is in the works. Sharing some
materials and design elements should result in a further saving over
doing them separately.

I don’t have a strong opinion about buying the lathe, but a suggestion for the frame:

 

-          Definitely Incorporate rubber (or similar) mounting  dampers between the coronet’s own chassis and the new frame.

-          Consider means to tie the frame to the floor securely.

 

I can see a material improvement in quality in my 3D printers where the chassis has been isolated from the world via damping – plus significant noise reductions.  The best approach seems to be to keep things as rigid as possible between tool head and chassis, allowing any vibrations to be transmitted into the chassis, and then damp the whole unit.

You can also build the frame from tubes and fill them with sand. The sand both adds weight and absorbs vibrations since it is free to move about.

looks like a great tool but without listing the cost or discount it's hard to say if i approve. even if we got a 50% discount but still cost £10,000 then that would be an issue for example.

cool in that case sounds reasonable with a good discount. i guess they
don't want to publish the discount but atleast knowing the list is
helpful. (i now realise i could have looked it up myself but point
still stands that would have been helpful in the question)

I see no reason for us to buy the coronet. And buying it will be detrimental to activities in the downstairs workshop - in the longer term.

We need to prioritise what what we do in spending/investment

(i) we've already been through this and we get little or no advantage over our current capabilities. Extending our capabilities requires a lathe beyond what we can do with the coronet

(ii) we are apparently not flush with money, to buy what we really want  (as highlighted in this thread   https://groups.google.com/forum/#!msg/reading-hackspace/cjwKGUrICWY/abh86atZAAAJ;context-place=msg/reading-hackspace/cjwKGUrICWY/abh86atZAAAJ and agreed by all but Toby [I think]) 

(iii) rather than spend that amount of money on a lathe that does not progress our capabilities, it would be better invested on other things that benefit more people (a Prusa printer for example) 

(iv) We've survived al these years with the Perfom and we can continue to do that until we have saved enough for a lathe that significantly improves our capabilities. Buying the coronet is just reacting to a youthful desire for instant gratification, it gives us no significant improvement on where we are now.

(v) while money is tight, we can wait until we can afford it - basic financial sense

Cheers

Hi. 

A conclusion was reached and the lathe paid for several weeks ago. This was based on this thread and f2f conversations with Andrew to make sure all was ok.

I've not posted about it, as I'm working through with Record what to do with the legs, as they will be surplus to requirements once we have constructed a workbench to provide a more solid base.

Thanks.

Toby

oops!
