At checkout they say they have to calculate shipping and get back to me cause its outside of usaIs it the same $1000 shipping for the Lee Valley one:

Hey guys
I am needing some parts to be made as flat, parallel and square as possible.
Here in South Africa it is just not economical to purchase a surface plate, cast iron or granite.
They start at around R16000 zar for a small one which is around 1000 usd
I can get a piece of laminated glass free and was wondering if anybody has actually used or tested the accuracy of glass in general as a surface plate.
I have searched for it and found a couple people talking about it, but none having actually done it yet.
I don't need accuracy to the millionths but looking at getting within 0.01mm of flat, parallel and square
Oh nice! Ill check them out and see!I bought a 300x300x70mm granite plate from Gem tool company in Pretoria (https://www.gemtool.co.za) about three years ago for only about R500. The inspection certificate claims it has a maximum deviation of 2.6 micron, which is probably good enough for the average hobbyist.
They are available here but i have no idea why they are so expensive. Everything fun here is expensive haha.
Biggest piece i will need to work on is 200mm x 300mm and made from cast iron. Its a project that im busy planning out which the parts need to align together as flat and accurate as I can get but dont need to be extreme.
Will only start properly planning parts if I can figure out a reasonable way of getting a flat surface to work from
Can you get a weld reinforced 3/4 "2 thick steel plate ? Fly cut the face on a warmed up milling machine of reasonable accuracy . It wont matter if the reinforcing is not dead parallel to the fly cut face as it's just the single cut plane you're wanting to use. Perhaps set the fly cut part in a 4 " slab of mesh reinforced concrete & use an engineers spirit level to get it true all round if you need it nearly true flat in all planes
Best of luck with the move. I hope everything goes smoothly and according to plan.Unfortunately all my projects have been placed on hold, going to be moving soon.
I hope you find a bigger pool of both new and used equipment.....and a bigger shop to enjoy it in!I'm also moving to a bigger city which will have more chance to find a second hand surface plate from somewhere.
Thanks!Best of luck with the move. I hope everything goes smoothly and according to plan.

Have you checked with Granite Grave Stone Markers, They are pretty close. I had a student make a surface plate from one. It was 36" x 36" and 4" thick. He made a stand with set it on 3 points. We used a precision level to test it looking for the flat part of the plate and we found a section that was with-in .0002"
