Thread: Granite Surface plates |
22/08/2009 08:45:12 |
My Tesco seems to have sold out of surface plates, so I went to Sainsbury. Theirs seem to be the same as the ones Geoff Theasby got from Tesco, ie. a pair and limited to 90 C. The temperature limitation may be due to the rubber pads and not to the material of the plate. I am sorry to say that mine are really not very flat at all, to the extent that I am going to try to do something about at least one of them. I have found out that "ATM" stands for Amateur Telescope Maker and that these gentry grind and polish glass surfaces to spheres, paraboli and optical flats! I shall see about plundering their books and suppliers of grinding paste etc. |

It's not much help being a UK subscriber. The site simply refuses to accept my subscriber number! |
Thread: Long term rust prevention |

Many thanks to all who have replied. Camellia and linseed do not meet my immediate needs but I will try to get some of Mike's Napier VP90. I shall also carry on with plans to set up a small nickel plating tank! |

G Thomas and Tubal Cain both recommend Shell Ensis oil for general rust prevention in the medium to long term. Reading between the lines of the only ad that I have been able to find, the stuff now named Ensis does not seem to be a straightforward oil. However good it may be, it does not therefore carry the endorsement of the Gurus. It it is only available in large quantities and may not be suitable for repacking by, for instance, ME clubs.
What are other people doing and what success are they having?
