if you want a smoother finish, make the mix with more water. Once it's poured, use a wooden float & gently smooth & smooth & smooth again. Basically play with the poured concrete - works a treat. This is a lovely instructable.

Hi PhilTilson, have you documented the process you used to modify your toaster oven please? I clicked on your name but no 'ibles came up.Best, John:)
& the coils for a Theremin.
what a brilliant idea! Thank you so much?
Thanks for the tip, I'll have a look @Placemakers & Bunnings (NZ).?
Thank you for documenting the process so carefully & with good pix too. May I make a suggestion for a step between six & seven? Even after careful ironing some of the mask doesn't transfer properly. I have a Dalo pen - very popular in the 1970's - & its ink is etch resistant. Use this to colour in any missing bits. I also admire your drilling lines...... any advice to drilling straight lines for IC sockets would be most welcome. Very good Instructable?
Here in New Zealand when I did woodwork class, it was referred to as manual training, this sort of drill was called a drill press.
I worried about the label also. Don't forget it's pressed into the vinyl when it's in the stamper so there's no way it will come off. Although I use my bare hands to wash vinyl I have never caused harm to a label - it will go very dark when it's wet but it always dries back to the original colour & contrast. I will try the record brush approach however & it's a simple matter to brush in the direction of the grooves & avoid the label altogether. In my opinion it's people who advocate solvents instead of water who are more at risk of damaging vinyls:)
I transfer records to digital as part of my job in a broadcasting company & can whole-heartedly recommend this... People often ask if I use solvents to clean & my answer is always "no" - just soap & warm water. Having said that, if there is sticky stuff which will not dissolve, I then try isopropyl alcohol. Do NOT use this on lacquer or acetate disks though, the groves will vanish!!! Nice instrucrable, thank you for posting it.John RobertsWellington.New Zealand.
