Thanks for all that info Bob.one question what does UNF mean ?
I can see your point by the tap following the old thread totally makes sense.
I have an old 14 volt battery drill thats gutless so could try that or my power drill has an adjustable speed control.
My Mum is going to check tomorrow to see if Dads tap and dye set is still there. (its 7.30pm here) and pitch dark.
thats a clever work around for your battery drill never need to buy a new battery again, you sure your not a Kiwi coz that sounds like a bit of Kiwi ingenuity going on there lol.
I found out last night while searching for the TVS90 that it fits the LV30/LAV30 which i reckon is what my kirby was renamed too, (its a VK30C) and the L stands for sideways valves and the V for vertical shaft both of which mine has.
So i have 2 options the tap and dye or Dead or trying to find a replacement.
The TVS90 that you have, was it easy to find in ozzie ?
do you have a local guy who might have one that i could email and see if he would post it ?
Thanks again Bob
Pete
