THE FAULKS 20" F4 DOB BUILD

[Gina]

Does the difference between 1/10 wavelength over 1/8 really make that much difference?

If you want to really mash your mind read this thread. It all gets a bit, well errrm, confusing

hi damian, didnt know he did that high a figure. only seems to advertise 1/8 which is obviously good

As far as I know he can, recently a 620mm if I remember correctly. I shall ask next time I see him 

Looking forward to seeing those pics of the mirror unwrapping

Are you making a shroud Mike?

I hope it comes with a Batman logo as an optional extra for cloudy nights.

i realy realy shouldnt be doing this, but i am so happy with the final outcome even though i dont have my mirror yet, and there is still a few things left to do, i had to share my progress so far. so here goes some more pics.

side bearings fitted for trial

ground board before blacking with centre shaft fitted and bush

then blacked

after 4 more addition coats of polyrethane varnish it was then de nibbed and machine polished

machine polished

mirror cover

reflection test and encoder grub screw fitted

from a far in the messy workshop

lower truss clamps trial fitted and good reflection test

hope you like. to get to this stage has took hours and hours, took near 2 days to polish, but all that is behind me now.

a couple of little mods to do to the cell tomorrow and then fitt that, and then re asmble the uta and fitted poles,e.t.c.

this should be the 4th pic down

Well done buddy. Looking sweet and finish is very nice. I sense someone is getting giddy 

Those mirror things are a law unto themselves. You can nearly have them finished just to go that little bit too far then its days to pull it back to start all over again.

It's probably why you have a delay. 20mins on the wrong stroke is all it takes 

Hope it arrives soon as the nights are lengthening
