    Thanks Crimson

    I almost have the actuator fabricated it's as close to yours as I could get working from Pictures.

    Some measurements of the main guide rail would be nice I think I have mine a little long! Also the length of the inside piece that slides in the main guide rail.

    Also I can't figure out how the spring is mounted on the inside piece that slides in the main guide rail.

    And last and most important how did you wire up the motor so it would stop and reverse at the end of it's travel I know that reversing the wires will make it reverse also what voltage do I use for the motor.

    As for the door Thank you for clearing up a big mystery about those guide rails I have racked my brain tring to figure out how to bend those sweeping 90 degree bends.

    Also for the door I almost have the hinges figured out I may need your help on those.

    Love your work this is the first time I have tried to do something like this and I am enjoying it.

    Try using a stepping motor. You can buy a computer controlled one from jaycar.

    Here

    You can control the motors direction and speed from your PC to.

    You have to assemble the kit yourself so you need to be handy with a solder iron or has a friend who has the skills and some time. This is one of the cheapest ones out there.

    keep in mind that every single moving part of the mechanism I made has screws for making micro adjustments. there is no other way to assemble this except to include the ability to make the parts mesh perfectly. You'll need a drill press for making precision parts, as well as a tap and die set.

    Question Re: How Do I make the Blast door from the Doom 3 project ?

    Crimson what kind of glue did you use to glue the tray gear strip to the aluminum?

    I first glued the CD gear strip to a thick piece of .80 gauge styrene with cyanoacrylate (superglue), then as you can see, it was screwed to the aluminum U channel

    Thanks Crimson from the pictures I thought it was glued directly to the aluminum.

    One question about the motor operation how did you wire it up to a switch and what kind of switch I'm guessing a DPDT pushbutton type switch.
    How did you make it stop at the end of it's travel, did you use a limit switch?
    Or just manualy turn it off?

    Also what thickness of styrene do I need to buy for the rails and blast door?

    Thanks

    Well here it is the linear actuator! It's not as purdy as Crimson's but it works! Still have some fine tuning to do and the mount to make but at least I'm this far!

    Here are some still pictures .

    I have it temporarily mounted to a wood block for testing.
    As you can see I had no styrene to mount the side gear strip to so I cut a piece of the cdrom drawer and glued it to that worked good!


    Here in this side view you can see where it differs from Crimson's
    I could not figure out the end spring he used so I made my own.


    This is a back view pretty ugly huh I still have some cutting to do to
    make it more tidy looking. Also I installed slides on the under side to give the whole assembly more stability.


    In this close up you can see where my gear assembly differs greatly from Crimson's! I could not find a cdrom with the same final drive gear as he used so I had to make do. I used the plastic part of the cdrom where these gears mounted to make it easier to get them in place. I put a very small bolt through the center gear and fastened it with small jam nut's. This let the whole assembly pivot to make setting the gear's position easier.






    Here is a Video of it in action.
