Haha love it. Some nice touches too it. 👍

If you type "ping pong" into the search box (no quotes, as I just did) you see there are a couple of topics in this section, discussing this very thing.   What I said in one of the threads was:   In 2000, ping-ping balls grew to 40mm (from 38mm). The hemis are roughly 100mm.   So the scale is 40/100ths.. or 2/5th.   A Mk3 Dalek is about 1521cm tall (or roughly 60inches), so a 2/5 Mk3 would be about 608cm (2ft). Nice size. Very wantable.   That said, you can get wooden half-balls on Etsy and eBay in a wide range of sizes, if you wanted to go for 1/3rd or 1/4th.

Hi,  I'm a complete novice at building (never worked with wood, MDF, plastic etc), but I want to create a "Dead Planet" dalek using the ping pong ball method. Factoring in my inexperience and cost (I'd ideally want to keep the build as cheap as possible, but without compromising quality too much), what are the best materials for construction?  Thanks. 

Hi all, well have decided to take the plunge. As an autistic-Im over fifty so been at it before it was fashionable. I need to be busy to be safe to keep the brain in neutral. So with an 11 year old who is obsessed with Dr Who i think i can achieve Dalek. I have a good knowledge and practial skills from restoring classic cars to games consoles.  the plans look good(2005 style).
