Digger project

Postby yaksplat » Thu Mar 06, 2014 5:41 pm

Hi all-

It's been a while and after building an arcade machine I'm now working on a digger. I purchased a mechanism off of ebay that needed some cleanup and fixing. The main spot that needs work is the coin mechanism and the assembly mounts at the two square ears brazed to the traveling shaft below the central turning shaft.
106

I also need to make a new chain winding spool as mine is not original and rides very high.

I've managed to get everything working beautifully as far as the mechanism goes.


If anyone can supply some nice pictures of the areas in need, I would appreciate it.

I don't recognise any of that geared mechanism or know what that video mech actually does? What machine and era does it belong to please?

That's what I get for posting while I was at work. Too little information on my part.

It's a 60's era carnival digger. The best example that I can find online is this: http://www.pinballrebel.com/game/tonka/tonka.htm
Unfortunately it does not have a good image of the mechanism that I'm looking for. I emailed the guy hoping that I could get a response, but that didn't work out.

The video of the mechanism is how the crane selects where it's going to drop. You'll notice that it goes to 5 different stops before returning to the start.
I believe that the original design was from the Erie Digger.

Here's a better video showing the full operation

I've talked to Jim a few times, although I was looking for a second resource. Jim mentioned that he sold off all of his supplies and inventory and it sounded like he's getting out of the business. I'm in his queue of messages to tend to, although as he said, I'm moving a whole lot faster than he is...

I want to turn a new chain spool with a clutch built in to keep the crane from wrecking itself. I may just to into free form mode and start just building parts.

Here are some things I'd like to know if anyone has some information

Clutch material. What is typically used? The one in my mechanism is many layers of some dirty oily material that I'm afraid to clean up that it may disintegrate.
Chain material. The chain on this machine is beautiful, with perfect links and no joints. I need a longer length so I'm looking for a supplier.
Calibration. Is there any method of calibrating the mechanism? This position with the crane here, etc etc etc...

I sent a few questions in an email to a guy in texas that bough a pair of restored diggers from Jim Roller. His response was a letdown of, "I can't get to them. Contact Jim."

I've usually found a hard piece of oiled leather as a clutch in older machines. As for calibrating, the mech should tell you that itself with a little experimentation of adjustments and teeth positions. I always tend to try a bunch of possible variations to see what works best. Amazing how many times they've been reassembled incorrectly years ago, often barely working but not smoothly or sometimes correctly!

I figure that I'll keep posting information here as I find it for future users.

Here's a source for replacement chain: http://www.franklinartglass.com/shop/it ... hain/4268/

Back to this project after a few years off...

Unfortunately I've lost my plans for the digger cabinet that I purchased from Jim Roller a few years ago. He no longer has them for sale on his website and I'm hoping he's still around answering emails. If I'm out of luck with him, does anyone have these plans laying around? Or would be interested in giving me some dimensions?

Thanks!
