I would love to tackle this project but i'm afraid my meagre or should I say non-existent glass polishing experience would have me running for the hills waving my arms and screaming wildly like something out of monty python.
Also they did'nt explain how to aluminize the mirror. All that work and no info on aluminizing??? ("Like we've all got pressurised chambers at home right").

I know about the pleasure of crafting something yourself as I hand built a three man canoe from wood several years ago. So I don't think the main optical tube would present too much difficulty. But the mount would present problems as I would want to install a motor drive system. And of course the mirror would be very hard to complete.

I think i'll give the "build your own telescope" in this monts magazine a miss. Knowing my luck and skill i would end up with a periscope.

Might be useful - if long enough to project through the cloud layers![:D]

True but you can overcome the cloud issue much easier with a RJ2079S "cloud" filter. They ARE very expensive (£200) but they allow you to observe pretty much any night,even when there is thick blanket cloud (the clouds in this case appear only as a thin whispy mist).

I might invest in one.

What do you think?

OK i just noticed that i posted the above CARP on a thread where people know how to grind their own mirrors. They aint gonna fal for my cloud filter joke. It would be better on a thread with lots of newbies.

I'm so cruel.

Yes you are.
You should be ashamed of yourself.
Naughty boy winding newbies up like that.
You should be purged.
You should be flogged.
Ahhahahahahahahahah(EVIL CACKLING LAUGHTER)
