Now i have some time to start working with the DW elevator again, some of you may have read about the first job i did so you know I spent a few hours with the elevator before.
https://pinside.com/pinball/forum/topic/modified-doctor-who-mpf-elevator

I was really excited about the suggested idea of using an actuator and did a video this summer of the elevator during game play, it seemed possible to use an actuator at the time but after some more testing recently with startup and simulating a interruption i realised it won't work, as you can see about 3:48 in this video the cam rotates clockwise past the bottom position to locate where it is after the shut down, this won't be possible to do with an actuator

» YouTube video

So my next modification will be similar to what someone did on dendocs elevator, but my intention is to make it as easy as possible for any DW owner to mount.
I have an idea of how to do this and i ordered some parts that I'm currently waiting for so i can begin, this modification will take a few months to finish and there's a chance I will fail but I really like the challenge of making a improvement kit to the elevator
I will update as often as I can or when have something to show, my English may not be the best all the time so feel free to correct me!

Cool, ill be following your progress

This whole project is brilliant. Well done so far.

The bottom of the outside bracket was slightly bent so while waiting for parts i reinforced it with a piece of flat iron to prevent it from bending again as i did in my first mod, I want the bracket to be as straight and perpendicular as possible because i will mount linear guidings on the inside.

In for the read

I made a new brace with tight holes and fixed distance for retaining the bracket in parallel.
I'll probably have to mount the linear units a little loose because the bracket is made of bent sheet metal and may vary somewhat dimensionally.

I have received the linear units, the quality seems to be really good, especially for this application.
My only concern is if the black dust that occurs inside the pinball machine will affect them.
I'll start making the mounts for them, still waiting for more parts though.

The mounts are finished and fits almost perfectly into the opening for the original rolls, I have milled them manually and grinded the corners to fit the opening, all parts for the prototype will be manufactured by hand because my CNC is not running yet.

attachment for the shafts on linear unit.

The linear guide block for shafts and mounts under the mini playfield is finished.
I did an offset on the attachment for the mini playfield so mpf is further back in order to make more space to fit cliffys.
I miscalculated it a lot so they have to be made again, about ⅛” instead of 1/32” , but it will work for testing.
I won't be able to do work on this during rest of December.

Thanks, so far it looks quite good but it's a slow progress.
As time goes by i find small improvements i can make on this prototype, i will use the pieces I have made in the test jig, if it works as supposed i will make new ones before testing in the pinball machine.
I bolted the sliding unit together with a piece of flat iron which has the same screw distance as mini playfield and made a short video clip to show movement manually.

That is great! If you ever made a kit available for sale, I would be in. My mpf has been giving me fits!

#15 1 month ago

I hope i will be able to make a kit, that's my intention if I succeed, i want it to be a reliable modification if I'm going to sell it.

I used my fixture to make threads in the shaft of the cam, i will mount a rod end ball joint here.
Except for the three holes in the bottom of the outer bracket for the reinforcement, this is the only intervention that has to be done so far on the elevator to install my modification.
A hole through the shaft with a nut on the other side might work as well, I'll check if there's enough space behind for a nut later.

William Hartnell
Patrick Troughton
Jon Pertwee
Tom Baker
Peter Davison
Colin Baker
Sylvester McCoy
Paul McGann
Christopher Eccleston
David Tennant
Matt Smith
Peter Capaldi
John Hurt

Or just say all your other games are Doctor Who too... but the chameleon circuit is broken on them

I'll just change translite to each and one of the actor's , I have not seen the series yet but I will for sure someday.
Three is more than enough for me, i got an opportunity to buy one more, it's being stored for the moment and one is used for this modification.
The third is in play, I have installed new speakers and Pinsound board in it, a really nice modification, especially with Doctorine’ the Tardis music.
This is a great pinball imo and a keeper for sure.

Quoted from darkpinball:

The series has had it's ups and downs.

The first two doctors were in black/white and not many shows are easily available. I used to watch them on PBS when I grew up. All but the newbie die hards will say they move too slow... but that's where all the original long-running character creation came from.

Dr 3 (Jon Pertwee) was a favorite. He was SUCH a lovable curmudgeon! Great stories and good companions.
Dr 4 (Tom Baker) had a long stretch and many of the old timers really got into him. The iconic scarf is probably one of the best Who Props! And who can say anything against Lalla Ward... my favorite Romanadvoratrelundar.
Dr 5 (Peter Davison) was good, but the traveling companions left me flat
Dr 6-7 (we just won't talk about)
Dr 8 was only around for a movie so, nothing much to see there
Dr 9 (Chris Eccleston) was a bit of a jerk but the story lines were really good and fit that kind of Dr. Plus, he introduced Rose who was one of the better companions.
Dr 10 (David Tennant) is my daughter's favorite. The stories were really good and his quirky character fit the stories very well. The younger generation tends to like this doctor; he was an EXCEPTIONAL Doctor.
Dr 11 (Matt Smith) was way quirky and the plot lines got really twisted (in a wonderful way) but you cannot watch Steven Moffat written scripts passively. You need to pay full attention to what's going on... then after you get to the end of the series go back and watch the whole thing again. The arcs in the plot that are not even arcs that you can recognize at the time. The stories are BRILLIANT.
Dr 12 (Peter Capaldi) has been out for a few seasons... I kinda like some of the stories, but his character just annoys me. The only saving grace is Jenna Coleman's character.

John Hurt played the Dr for one episode which was very fun. Watch the other doctors before seeing this one.. it will make much more sense.

My suggestion is to start with David Tennant; work forward from there and then loop back to Jon Pertwee.

As you get deep into the Doctor, look at the backstory and some of the facts behind the camera. There's a lot of great documentaries out there about the start of Dr Who that include the original producers and Verity Ann Lambert's groundbreaking first female in a very male producer club; the call for "No BEMs" (Bug Eyed Monsters); also, some of the fun facts... like Tom Baker married Lalla Ward (his companion) and Peter Davison's real daughter Georgia Moffett married David Tennant after she stared in an episode titled "The Doctor's Daughter" (she was supposed to be a genetic merging of David Tennant's Dr.) ...a bit incestuous no matter how you look at it.

Have fun with the backstory and good luck on the mod!

Thanks for sharing the backstory, interesting reading from someone who knows the series, I'll start looking for it, seems like I've missed something and have a lot to learn about Doctor Who.
As for the modification i will hopefully start some testing during this or next week.

It's up and running!
I made a mpf dummy of a thick flat iron with a weight of 2.5kg, the original mpf weight is almost 2kg.
I added some extra load with a weight of 2.5kg, so the total load of 5kg is about 2.5x times more than normal.
This was only for testing, it won't be good for the gearbox with a heavier load in the long run.
These parts will not be installed in the pinball because the mpf level will be a little too high, and too far back.
My CNC is working now so i will make the new pieces with it, I'll do my best but our second child is about to be born any day now so don't have to high expectations on this for a while.

You gotta have priorities ... work on DW! (Just kidding)

Best of luck with the delivery!

Thanks, we are looking forward to it.
I will at least try the original mpf in the test jig within a few days, I'll post a video if it works as supposed.

I want to spare this topic, and the followers from my personal life
I can be added on other social media like facebook or whatsapp, though I'm not so active on them it's interesting to know people with the same interests, just send me PM.
Here's a video of the elevator mounted in the test jig
