TAM 120 replacement terminal box cover ... (new hat for Frankinpump)

[K.H]

When you have the lid off Frankenpump, could you have a look at the wires please?
When mine blew it was the top that went so i have no + or - signs, i have a Yellow and a Red wire, i would assume Red to Positive, but it wouldn't hurt to make sure

I left the comfort of the log burner and ventured out into a cold shed.  On close inspection I'm surprised the thing runs at all ... there's a bloody great hole in the end of it and it's all black, so if there were originally polarity marking on it, there certainly aren't now!

Probably not much help as it may vary manufacturer to manufacturer, but looking on the pump end towards the motor, the red wire is on the right and the printed spec on the capacitor body is facing up towards the terminal box lid.

Think I'd better go and buy a new capacitor too!

[Julian]

Anyways ... I thought oakwoodtv said they were not polarity sensitive for this duty.

Is the one you bought marked + and - ?

[K.H]

Just re read Oakwoods post, you are correct, funny first time i read it, i read it as they were specific, hasn't arrived yet but i want to run it as soon as it does, it died at the end of a first stage

[oakwoodtv]

Just got in from the pub so excuse the spelling electrolytic capacitors used for DC normally have a positive and negative terminal unless its marked bi polar.

AC capacitors will work ether way round as the voltage changes from positive to negative 50 times a second and they are destined to work with the alternating current.

If this makes no sense I will have a another go tomorrow.

Amazingly I kind of understand that!

Amazing due to my normal inability to understand simple electronics, not for the sobriety of your explanation.

[Julian]

Amazing ... it fits!!



I know not many members (two to my knowledge) have 3D printers, but in the spirit of sharing, knowing that non-members who may have a printer have access to the wiki and that the technology will grow in popularity, what are peoples thoughts of making the file available on the wiki?  I'll get shot of the Frankinpump name and perhaps, as Jualinf suggests, add the biopowered logo.  Defiantly puts biopowered at the "cutting edge" and, over time, other items could be added.

Tony/James ... I've vague recollections of downloading files from the wiki being a security issue, is that right?  Can it be done?

[Julian]

In a similar vein to the comments in my last post, I've made the thread name a little more search friendly!

[K.H]

If its possible i think its a great idea

[julesandtash]

How about doing one for TAM105s as well Julian.
If you do, I will buy two off of you as both my pumps have busted terminal covers (OK one is a genuine TAM105 and one isn't but takes the same sized cover

[Julian]

I'd be happy to provided you don't hold your breath whilst I do it.

I'd need a broken one to measure and copy though.

[photoman290]

have to take the cost in to consideration though. a new tam 105 cover is only  fiver or so.

It's about 4 minutes to set a print going and a couple of quid in plastic (for the TAM 120).  To draw the file in the first place can take ages and, if priced commercially, could run into hundreds of pounds.

I made a couple of little inserts to extend the fuselage of a model aeroplane.  The chap said he knew dozens of people who would be interested, they could be sold over the internet for a good profit and he'd advertise them on his model forum, so I made him a couple FOC.  It took me many evenings and several prints to get them right and guess what ... I never heard another thing, but last I heard his model is coming along nicely!

So costing is a funny thing with this printing lark, the actual, realistic cost can be quite high, but the perceived value is usually low.  I guess that's why 3D printers have only found a commercial niche for prototyping.

Anyhow, Jules is a very wealthy man now he has no heating or electric bills, so I'm sure he can afford it!!

Neat, that. Super cool.
It'll look pretty impressive on the Wiki anyhow. Over time, more peeps are bound to start getting 3d printers.

and last about five minutes when splattered with biodiesel - ask me how I know

If only - it has taken quite a lot of investment (read borrowing) to get to this stage which I am now trying to pay back
My heating bills are not actually zero, my heating and CHP bio is around 28ppl so not free but a lot cheaper than kero or red diesel. Even at that price, the lister generated power only just about equates with grid power. Only by running in full CHP does it really work out cheaper than using mains power.
You may well have read my discussion on VOD (mainly myself and hifly recently) and seen that it's not quite perfect and there is still some work to be done (read more investment)

But yes, I would still be very interested in a couple of TAM covers. Mine are too broken to be of any use as a pattern but would happily buy a pair of new ones (main terminal housing and top cover) and send to you as patters if you are up for it
