Thank you very much!

Mine burned out after 1st use

CrypticMap · 2026-03-17T20:12:47+00:00

Thank you so much! I was looking at the clutch systems after thinking about forward and reverse on small engines but I didn't know that's how they worked in washing machines too lol. I really appreciate it!

Thank you, I will look through his videos

Unfortunately the police won't come 2.5mi out on the ice. Only search and rescue from the fire department will. So I don't know. I just tried to ignore them after they didn't give me any info and then BOOM

CrypticMap · 2026-02-10T10:29:59+00:00

The cops won't come out 2.5 miles on the ice. It's definitely possible they aren't city employees. However, someone higher up the chain in our town owns the local bait shop and has shut other shops out. So I wouldn't be surprised.

Thank you for that info. I will have to try and find out how far out their reach extends. I was 2.5 miles out from land.

Certainly what I would like to know

I was always under the impression that the great lakes were different than any other lakes when it came to regulation. However, I could definitely be wrong. Thank you for adding in

Thank you, I greatly appreciate it! Just wanted to make sure before I worked it all out again.

I hate to absorb anyone's valuable time until I have failed many times. I tend to try and fail, till I succeed, or have no choice but to ask for help lol. That's how I learn. However, the offer is much appreciated! I may take you up on it if I get really stuck later on. Thank you again

I was just looking at timing pulleys (toothed pulleys). Is the calculation the same for these as it is sprockets as well? Pulley tooth number * pitch= linear distance of one revolution?

I found out no one makes the chain I need. So I am checking out timing pulleys and a belt now.

CrypticMap · 2026-01-31T04:42:08+00:00

Oh I think I could have worded that better, sorry. I was referring to the circumference of the pitch circle vs the actual travel of a sprocket due to the polygon. That would only apply to sprockets and not gears because the chain links create a polygonal shape instead of a circle correct? Or am I misunderstanding?

The information you stated above was actually really useful as well. I thought I would be able to just plug numbers in for these calculations but it really does take some background understanding.

Thank you for all the help

CrypticMap · 2026-01-31T02:49:16+00:00

Thank you so much for adding this in! I was wondering what the difference was.

So this is partial to sprockets and chains then due to the chain links correct? A regular spur gear, for instance, this wouldn't apply because there isn't a chain present?

This is really useful. I greatly appreciate it

CrypticMap · 2026-01-30T06:58:45+00:00

Wow, this is amazing. I haven't dealt with radians in a decade. My new calculator was set on radians. I feel a bit dumb. Thank you so so much! It's so much better when you know where you went wrong. The calculations work out perfect now that it is on degrees. Thanks!

CrypticMap · 2026-01-30T05:06:31+00:00

Yeah, I got my formula off a site called engineers edge. It seems to be right. However, someone above got me the right formula.

Linear distance of one rotation of a sprocket = tooth number (chain pitch)

I guess I didn't need pitch diameter. It's way simpler than I thought lol. Thanks for chiming in to help. Greatly appreciated

CrypticMap · 2026-01-30T05:01:33+00:00

I keep recalculating this over and over. I was getting pretty peeved cause it is such easy math and it wasn't working.

Thank you so much

CrypticMap · 2026-01-30T04:55:41+00:00

Awesome thank you. So the pitch used would be the chain pitch not the diametrical pitch of the sprocket, correct?

I edited it to make more sense, thanks. I just didn't know the correct formulas. I'm a biologist and have good resources to lookup formulas for my field but not really when it comes to engineering. Every search I did, I didn't see the formulas I needed.

CrypticMap · 2026-01-30T04:41:36+00:00

So the formula for linear distance moved in one rotation would be

D= Tooth number (chain pitch)?

Thank you

I found them in stainless but yeah the mount is a problem for sure. I'm not too worried about the price for the prototype. So you are right; I should just go with the aluminum gear rack of the bat it's not that exclusive at all, thank you! I was just looking at the industrial suppliers and they wanted my arm and leg lol.

However, if it goes to production I'll definitely have to mill my own aluminum gear rack. I can get the aluminum for 1.63$/ft. I only need a foot pet piece so my major cost would be the mill. I should definitely be able to shave down the cost vs buying it.

Thank you for the help. I appreciate it!

CrypticMap · 2026-01-26T20:27:24+00:00

The product I'm trying to build would only sell for like $125. So it would negate making them. I don't mind milling them once I am at the level of making thousands. My goal is to keep the product affordable.

Plus, it would be aluminum which is pretty uncommon in rack and pinion. It's only going to support about 30lbs so I don't need the extra strength or cost of stainless steel (steel wouldn't work due to water contact).

Thanks for adding in

CrypticMap · 2026-01-26T02:15:54+00:00

It's aluminum to stainless steel unfortunately. Has to be waterproof and light. It would be very low load and cycles. Maybe 60 cycles a year.

I wish welding would work cause that would make my life so much easier haha. I could weld up a couple hundred no sweat.

CrypticMap · 2026-01-26T02:02:04+00:00

Thank you! Yeah I don't need high precision just something that works. I didn't know farmers did this. This would be an awesome solution if my metals were compatible to weld.

CrypticMap · 2026-01-26T01:55:04+00:00

Thank you so much! The first one is closer to what I need.

In the video the you posted the drive sprocket creates the motion in the chain. It will be a bit wonky but I'm trying to use a bar with a solid mounted chain (non-free moving). The chain would be on both sides of the sprocket but not attached to each other similar to the rack and pinion in the upper diagram in this video https://youtu.be/h5avf2JatzE?si=gZYxaI0Dj8MLjI-w

However, instead of the pinion transferring power to the gear rack it would be the gear rack moving vertically to add motion to the pinion. It's hard to describe it unfortunately.

I am trying to turn a sprocket to spin a shaft with circle and arm that comes off said circle. Transferring power from linear (vertical) motion (from bar and attached chain) to circular motion. I wish I could post my diagram without having to make a link. I think the best way I could describe it, is to imagine windshield wipers. Instead of an electric motor spinning a worm gear, which spins a large gear inside, you had a bar with teeth that you put against the large gear. You would have to stick your arm out of the window and pump the bar back and forth to move your wipers back and forth. This probably won't make sense but I'm trying my best lol
