:lol: I was not looking at where you where when I mentioned it. It is pretty dam heavy and would be at least more than the cost of the wheel :?
I think you better keep looking ;)

I was talking to the Misses today wondering what it cost us to get extra power points and extra phone line and extra antenna outlet. It was a total of about $200. Although the electrician likes us. We have had him around every time we rearrange the house. The last time just as he was finishing installing a phone line for the computer he noticed a phone line point less than 2 meters away (about the length of the couch against the wall)) from where we asked him to put a new one :oops: :lol:

Anyway make sure you do the rounds and consider what other work might need doing at the same time as you get the 15amp outlet. As far as I understand the only difference between a 10 amp and 15amp outlet is the fuse switch. That what I understood from the last electrician I talked to any way?

unfortunately brett, this couldn't be further from the truth.

there are many differences, and although a 10A outlet may be able to take 15A running thru it for a period of time, the 10A outlet is not designed for that and may well be damaged. the conductors will be bigger in a 15A outlet and notice the bigger earth pin :?: this is your safety cable, how's yer safety :?:

depending on your cabling and circuit breaker, you may only have to swap the power point... get your local sparky to check everything first tho, and never do it yourself, it's simply not worth it.

Like I said my understanding came from a chat with an electrician. He was in a hardware store the same time I was buying an extension cord for my 15amp welder that I use at home.
From a bit of google research this morning it seems in Australia the wiring is the same size for 10amp and 15amp but the main difference is that a 15amp outlet is a dedicated outlet. In that a 10amp fuse often has multiple power outlets running to it. The 15amp runs on the same wiring but only allows the one unit to run from it. Hence a 15amp dedicated outlet stops you from running multiple appliances on the same line.
Only if you start changing the value of the circuit breakers are you gambling with your safety.


This is basically an issue we are up against often in the welding industry. You are welding away and someone decides to use a 9 inch grinder some where in the same circuit as you and bang the circuit breaker cuts the power. The Grinder must be plugged in to a different circuit or else not used at the same time as the welder. This can also happen with multiple high current 10amp appliances.
I use the 15amp welder at home on 10amp outlets (either change the plug or it is simple to grind down the earth pin to suit the smaller outlet plug) I don't remember overloading the 10amp breaker yet but I have not done overly hot welding at home. As long as you don't go mucking around changing circuit breakers they will tell you if you are overloading the circuit. One thing to remember is that an extension cord increases resistance so the shorter the better.

Off course a dedicated 15amp outlet is the way to go especially in the case of firing a kiln as you don't want a circuit getting cut as you are firing.
I forgot about this last time the electrician was here I will be sure to get a 15amp dedicated outlet next time we get him in.

This is the best understanding I found in my extensive :roll: google search!

Thanks everyone, sounds like paying the sparky to have a delicate 15A socket installed is the way to go. You are right Brets , I wouldn't want the circuit breaker to shut it half way through firing. As to the wheel, I found one on eBay that is located near me (Posting is not a good option as all pottery wheels are too heavy). Please comment on the price. http://cgi.ebay.com.au/Electric-Pottter ... 1c0de9a3d0 .
Thanks

This is the sought I have for sale at $70 but mine is much better condition.
http://cgi.ebay.com.au/Pottery-Wheel_W0 ... 35a4cec088

This is the electric type that I use at the pottery club and seem to work great.
http://cgi.ebay.com.au/VENCO-ELECTRIC-P ... 5636e1f8d6

The electric one I am getting I haven't seen yet but it is going for $100 from a pottery friend.

I am not so sure about the one you are looking at. It states stand up. I am not sure if that is a good idea. I guess you could get a tall stool. Like I said I am getting mine for $100 so $300 sounds pricy to me. Maybe one of the experienced potters have a better idea :?

It may take some time to find the right one close by?

Bretts, that electric one you showed is a good one. The brandnew one would cost nearly $1000. You are lucky to obtain one for $100. $300 for a second hand wheel sounds dear for me too. It's hard to find anything here in Brissy. I'll wait and keep looking around to see if there is anything else coming up. Thank you for giving me some idea about the pricing.
