Apogee GTX

[IanY]

I can attest to Nikhsub1's statement that bowing is a one way street. I have tried re-installing the low profile washer and the temps were a disaster.

I like these forums cheers for the quick replies guys.

IanY, first attempt at metal lapping (after practicing on some scraps first), have figured a telescope mirror before though, but I cannot attest to my skills with metal unfortunately, so for best performance bowing is the way to go with the GT/GTX.

I would tend to agree with you aswell that there will more than likely be no outright winner. However, one factor that could decide it in the D-Tek's favour (for me) is if it offers comparable (+/- 1 or 2 deg) performance to the GTX bowed then it would seem a clear choice as it avoids the required bowing (easy, hassle or otherwise) of the GTX.

nikhsub1, I think I understand the reasoning behind the bowing better now, makes perfect sense. cheers.

And phelan1777, thanks for the welcome

I hope you are aware that the D-Tek comes bowed already.

IanY, I am now! I'm also aware I have some more reading up on the subject to do, off I go

ziddey thats very interesting, I had planned to order some sandpaper up to 2500grit but will do some digging around and see what the experts are saying

That is very misleading... the dtek block is not bowed in the way swiftech bows the apogee... it is not due to an oversized o-ring it is more to do with the way the block bolts together - you can't bow or unbow the fuzion... yet.

hmm, one can attempt to relap it (make it flat) like someone I know
but there would be no return to a bowed state I guess

if this block had a center support it wouldnt need a big convex forced in it.
(take a catchup bottle cap and press the center, no center support means it doesnt stay convex or even flat)
