    When I have time Im going to stop by this 3D print store by my house and see if they could 3D print a new 8x10 frame for the v750 series and 4990...it seems doable right?

    Had a piece of 1mm aluminum laying around so cut myself one just a bit smaller than the Epson film guide with tab and all :

    Mistakes (it seems that I like to make them myself) :

    1) The tab is obviously only there to help you lift out the flimsy film guide : Does not to be reproduced on a rigid frame.

    2) While it fils nicely in film holders, 8x10 Ektascan BRA sheet film is actually not quite 8"x10" : It actually IS smaller. I had allowed the inner dimensions of my new guide to be slightly smaller than Epson negative guide with the idea that it would be easier to tape the negative if it was at least slightly supported by my frame : Not even close as the negative is hanging out not from the inner edges of my holders but from a width of flimsy masking tape. Following advised dimensions should be a big help but I would suggest checking the actual size of the sheet film you are using (found a noticeable difference with very old agfa 8x10 sheet I had on hand.

    Now,
    8x10 is really quite larger than 4x5. Would appreciate some confirmation that it is indeed possible to attach the negative to a frame with enough tension to keep its surface flat, at a thereby consistent height above the scanner's glass, like the Epson can effectively do for 4x5.

    Have been doing some small experiments with 1.5mm glass as well but the results are not yet up to my expectations : It seems that I am able to improve contrast but have yet to see an actual improvement in actual focus. Still have to experiment with various spacers.

    This maybe what has been referenced by a previous poster but what about using some of that "museum quality no reflections at all invisible glass" to use to support the negative to the target height ? (around 90$ at a "Michaels store" in Montreal).

    As would I. I would buy 2 if it made the number high enough for production. Spares are good.

    Sounds like an interesting solution, I would have one too... If you're shipping to the EU that is.

    Well I finally sat down and cut myself a Ben Horne style 8x10 holder. I used the exact same one he used, which I got from the Target website for about $8 dollars (US).

    First, the good news: It works! I made a scan last night that was free of newton rings and acceptably sharp for a print up to maybe 16x20, which I feel like is about the limit of the V700 anyway (esp using using lower res lens).

    Now the bad news: It's still not perfect, and not super easy using an exacto. I basically cut the outside using the Epson Film Area Guide as a template. For the inside I used a failed Portra 400 negative to try and get as close to the edges as I could so I could still get a 'full sheet' scan. I was basically successful in that, but I cut a teeny-tiny bit too big, and I have to do more taping of the neg to properly fit it. Honestly, if you have a big light table that would make mounting a LOT easier. I'm thinking work with the film as much as you can with lint free gloves. I may order another $8 dollar pad to see if 2nd time is the charm. Arts and crafts were NEVER my strong suit, but what I did was 'acceptable'.

    Is somebody here still trying to organize a batch order of a metal holder? A precision cut metal holder would be ideal IMO. I have no idea where to even start looking as far as a metal shops. The rubber mat thing works ok but if someone organizes an order for the original metal design COUNT ME IN. :-)

    I wet mount 8x10's directly on the platen glass. Scans look pretty sharp.

    Do you mask off any areas on the scanner so you don't get mounting fluid in the scanner somehow?

    Is this going to happen? Seems like a lot of interest.

    I would still be happy to arrange it through my dad but I got the feeling that price was not reasonable for everyone at around $70-$80 USD. Does anyone know another source to potentially get it cheaper? Happy to help if it's needed.

    Having made several of these from aluminum myself, I think $70-$80 USD is reasonable.
