Tell us about yourself!
Actually, I think it was 200!
It always worked perfectly (the machine was dismantled som time ago)
I think I bought 100 of them from eBay for around 10p each
If you look at the second video (The Ball Unit), you'll be able to see that the top ball in a column flips a lever so that the next ball gets deflected so that it can trigger the release of all the balls in the column.
There aren't many synonyms for 'bonanza'. There have been slot machines in the oast called 'Cascade' and 'Jackpot'.
...or even 'past'...
One of the meanings of bonanza is a stroke of luck, which the player needs to win the jackpot!
I’ll have a go myself tomorrow
Yes, but the fewer the number of columns, the less fun the game would be.It was only by having as many as 14 columns that I was able to have a jackpot. With fewer columns, a jackpot would have to be smaller because it would be more likely - but then it wouldn't be a jackpot!
I'm working on a new machine at the moment, but I've got a long way to go. Like many of my other Instructables, it's too complicated to explain in detail how to make it from scratch, and so it isn't really an Instructable at all! I will, though, put in on YouTube when it is finished.
Tens of thousands! When building my latest machine (the Bouncing Ball Amusement Machine), I constantly ran out of pieces because I wanted a certain colour theme, so I bought pieces a thousand at a time (from ebay). Here in England there are 'car boot' sales which are usually held in a large car park or field, and these have been a good source, but I ended up with an imbalance of useful pieces and decided that buying specific pieces from ebay was a better bet.
On each reel, each number has a slot, the depth of which is related to the value of the number. 0 has virtually no depth, 2 has a shallow slot, 4 a deeper one and 8 the deepest. The big lever at the top of the machine drops down at the end of each game and falls to the level of the shallowest slot. The further the lever drops, the more balls get released.
Hi there!I did it over four months, doing a bit every now and then.It probably took about 200 hours all in all.
What a nice comment, GB35. Thank you.
Thank you, Penolopy. I really enjoyed making it.

Oil will not damage K'Nex. Use dish-washing liquid in warm water to remove it.Apply the oil with a small paintbrush.
Great stuff!I guess you don't need any advice now!
When my clock kept stopping, I oiled the escape wheel pivots and the problem was solved.I would recommend oiling all the pivots (with a thin oil) and the escape wheel teeth.
Send me a photo of what you've done so far.
By the way, I've noticed that your comment is nested under someone else's one! You need to avoid this for a new comment.
Thank you for your comment.I am very happy to reply to specific questions, but I am not prepared to produce detailed step-by-step instructions (as in a K'Nex instruction manual). You will therefore need to be a bit creative, not just an instruction-follower—and I'm sure you are if you have a 3-D printer!I still have the machine and so I will be able to provide more photos for you—just let me know the specific areas.
Are the green teeth evenly spaced enough not to jam? — the challenge here is to make sure that the orange 2-way connectors aren't too sloppy.Having said that, well done! It's great that you're being creative instead of just following instructions.I'll let you know shortly how to make a ratchet — I couldn't use the method in the grandfather clock, but it will be useful for you.Ted
Ah ha! I remember where I saw the idea!
I mean, made it from that faint memory.
I think I saw the idea in an Instructable some time ago, and made it from that.
Great stuff.Even if you don't have an hour hand, it's a very satisfying tick!Ted
It would be great to see a picture of it.Ted
It is fair to say that without an 84-tooth gear I would not have even started to make a clock!The number of teeth on the three K'Nex gears is 14, 34 and 82, and these are very strange ratios. You can simulate a 2:1 ratio easily enough (by using an 8-way connector with 4 rods around the outside), but it's the 6:1 ratio that's the problem.What are you going to do?I'll do some Googling to see whether it's possible to get an 84-tooth gear...Ted
Hmmm... not looking good.There is an 84-tooth yellow gear in the K'Nex Education Renewable Energy set, but the set is very expensive.There is an 84-tooth green gear on ebay.com but it's nearly $40!Your best bet is to buy second-hand K'Nex and hope you get lucky (the 84-tooth gear has a smaller shoulder near the middle and is a paler yellow than usual).Ted
There is one on eBay too:https://www.ebay.com/itm/KNEX-Ratchet-Outer-Bronze...Ted
Yes, that should be fine. The purpose of it is to make sure that the white rod in the adjacent slot moves as little as possible.Let me know if you have any more questions.Ted
Here in the UK I sometimes buy new parts from the K'Nex User Group.The ratchets are difficult to get nowadays, but you can buy one here:https://www.knexusergroup.org.uk/en/knex-parts-oth...Ted
Sorry, but no!I explained in the introduction that the dial and case were left for the builder to do, according to their taste.The Instructable covers the complete construction of the mechanism; if you are an instruction-only K'Nexer and want to build a complete clock, then this construction is not for you!
In Step 7 there are pictures of the weights: I got some sheet lead and rolled it up, and made sure that there was a hole down the middle to that it could be attached to the end of some strong cord using a pulley.You do need to look at the photos.
Thanks for that.It was built over a two-year period. Every now and then I got stuck and had to leave it alone (once for six months), and at times I was about to give up because I just couldn't see how to progress it any further.Perseverance, and intuition from the cosmos, enabled its completion.

You may like to know that I've just finished a smaller one: No Instructable yet.
What a nice thing to say!Thank you.
Thank you for your kind comment, Kyle_M.I'm currently working on a much smaller fruit machine, but it's quite a challenge...Stay tuned.
Thank you, kind sir!

That's brilliant.Two things:1) It's difficult to see from the photos exactly how you have made the reels. Any chance of some more close-up photos?2) How have you switched the motor on and off?
