OK great but I would not have thought the target was a 10 pointer!

The vid playfield restoration thread is superb

A terrific articulation DF of great value

Undoubtedly John there is lots to do and at times it can become quite overwhelming. But you have a great basis to move forward on Atlantis and in particular your Atlantis.
The playfield overall looks pretty good to me and pretty good relative to the many pics we see of Atlantis on this forum. It would be nice to see some backglass closeups and reverse side. I however cannot urge you too strongly to strip as far as possible the playfield as earlier posts have suggested-the wireforms and star rollovers excepted. You will appreciate the effort in time to come.
For the preservation of the playfield, for gameplay and as you marvel at your machine from to time the sheer pleasure of looking at this thing of beauty which is literally gleaming (at you) as a result of your efforts.
You have a star studded machine in your midst which is just longing for your attention. Enjoy

That's a terrific expose of drop target bank maintenance DF. I agree as you say this a tricky undertaking-for me probably the trickiest and certainly more so than score reels.
It is not complex but boy it is tedious & time consuming and those damn springs by the end give you blurred vision re their identity!
I did a complete overhaul of my 4x4 High Hand drops and there is no doubt once it is done it makes a world of difference on how cleanly & precisely they drop & reset. One thing I found is do not try and remove the rubber stops as in all likelihood they will be perished to an extent and, for me at least, replacements were hard to come by.
I am currently overhauling my El Dorado 1x10 & 1x5 drop targets which were pretty oiled up where someone has used the lube route. But I decided to take your secondary route DF. That is removing the back plate (with rubber stoppers) and cleaning from there. I must say I was pleasantly surprised where with detailed cleaning they came up I think pretty well and I am happy with the result. The true test however will be when the machine is back to play.

Yes I was desperate to replace at least 6 on my High Hand which were completely deformed. I managed to get the 6 from John Robertson in Jan 14 and was very relieved. I think that was all he had as they do not now appear on his parts inventory.

Separately I purchased a grommet assortment kit and although there was one group the correct size they were made from a non rubber substance which was non pliable and therefore unusable in the pin context. I would be confident of sourcing however a generic replacement if needed.

I have just completed a resto on my El Dorado. On the 10 & 5 bank drop target sets I utilised plan B set out in Dirt Flippers' post 123. That is I removed the back plate and did all the cleaning from there in a particularly detailed fashion using Krud Kutter and a soft toothbrush and Novus 2 on the targets. In gameplay the targets drop & reset precisely so I was very happy with that approach. I accept however that the metal parts lack the pristine look and sheen of those by Dirt Flipper in post 123 but I believe it is a good approach where time, turnaround & accurate gameplay is important.

I could not help myself jr

That's interesting DF. On El Dorado the 10 target bank is supported by two rubbers but with posts in the centre. I take it that could also be a mod on Atlantis to reduce the ball strike force particularly in the centre region.

You are right my error. I wrongly interpreted the rubber diagram and my Atlantis is yet to arrive.

Thks DF. I recently completed a restro on my El Dorado. I purchased a ring set from PBR but it did not include the extra rings to double up.

Oh dear DF-you have got me. Invoice indicates 8!! Checked my ElD spares box and there they are-3x3" rings. At the time I was not conscious of the doubling. Does the second ring go immediately below the post centred ring? As usual thks so much.
