| I have spent tons of time searching the internet, emailing companies, and calling distributors to find a bevel gear. Here are our best options:
Option 1:
I have finally found a place that will make us one to our specs - Warren Pike Associates. Over the phone I gave him the following dimensions: .875" bore, stainless steel, 1:1 ratio, 10 pitch, 20 deg pressure angle, 30 teeth. This should get us a rough estimate of the price, and when we could get the gear by. Don - if this is what we choose to do, I will need the exact dimensions of everything ASAP, so I can give them to WPA for the actual design so we can get it done, and get the part as quickly as possible. This option has the benefit of us getting exactly whatever we want. But it may take longer and/or cost more than...
Option 2:
Quality Transmission Components. Basically the first place we found that would actually sell anything online. The gears are metric, and we would probably have to machine them ourselves to get the right bore. The benefits are that the parts are stock, so we could probably get them sooner and/or cheaper. Here is the website: http://www.qtcgears.com/rfq/default.asp?Page=../KHK/newgears/KHK230.html Look through the miter and bevel gear pages to get exactly, or at least close to, what we need.
Option 3:
Buying an entire custom marine gearbox through Rino Mechanical. http://www.rinomechanical.com/gearbox_custom.htm#TitleBox They have built gearboxes (as it says on the website) for similar purposes. I have contacted them and believe I will be able to get some pricing/timing info tomorrow as well. This has some great design benefits. We won't need to worry about bearings or alignment, etc. : the box will be professionally constructed. It may be the most expensive and/or take the longest, but it should definitely be the best. And as long as we get it before Weeki, installing it shouldn't be difficult if everything else is constructed.
There you have it. Give me some feedback tonight, because I will be in contact with WPA and Rino tomorrow.
-Andy

| I think we had a professionally done gearbox last year, but it was from McMaster. As long as all of the parts, bearings, etc are stainless steel or aluminum, we're good.
I think the gearbox and Warren Pike are viable options, but we need to get on this ASAP so we can have a drive train at weeki wachee.
how hard is it to align gears and put bearings on yourself? Sounds like something that is easy to screw up, and have your whole drive train not work. | |

| ships in 6-8 weeks, and is $874.39
I just have no idea what to do about Weeki Wachi at this point. Could we, just for the testing, fix last year's gearbox? Replace whatever rusted - bearings or whatnot?
I'll just keep looking, I guess.

| fuuuuuuuck!!!! yeah i don't know. Maybe we can get the old bevel gear to work for weeki wachee? i'll see if i can figure something out. | |

| oh wait, Scott had an idea involving 2 sets of helical gears to make the total angle add up to 90 degrees. Call Scott or Don. If you don't have their phone numbers, call me. | |

| oh but double check that its the right size, and not like micro-machine transmission sized. | |

| Did you check any websites that make you log in to see prices? I just made an account on this website, and you can see bevel gear prices.

I just clicked on a random one to see if it was ridiculously expensive and it is not.

| Wish I had found WC Branham sooner. BY FAR the easiest to work with, best selection, most helpful. FOR ALL FUTURE HPS TEAMS: CONTACT BRANHAM ABOUT YOUR GEARBOX FIRST!
Here is the link to the quote for the 5 different boxes I was looking at. However, lead time is still 2 weeks even for the quickest.

And here's the link to the CAD drawings of the cheapest one (which also happens to be the smallest, which is good).

| Andy, I clicked on the link and it didn't work. Is this a link to your email? Can you take a screen shot and upload it? or can you just give me a range of prices for gears we might actually use? I was thinking of just not having variable pitch on the backup drive train (what we will test at weeki wachee). First we'd have to design and build everything. then make sure the EEs are done with their part. Then waterproof everything. I doubt we can do that in time for Weeki Wachee. I have the CAD mostly done, just having dropbox issues. The only parts we would need to manufacture are the hub and the drive shaft. We might need new pedals because i cant find the other pedal! we have two cranks, but only one pedal It might be in the sub house somewhere, but if we can't find it, we have to get new ones. Maybe cheap crappy ones, just to test? | |

| Here is another website. Tim Martin says he orders stuff from them all of the time.
I'm going to head out to see Moses to see if he can fix the prop mold, and Dr. Lear to see if he has any other suggestions about the bevel gear so that we can use our linear actuator. | |

| I asked Braddock, and he said to call martin sprocket and gear http://www.martinsprocket.com
They might not have it in their catalog, but they can make stainless gears, and they won't be ridiculously expensive. Also, he said to consider brass. But we need the torque calculations before we call.
