I’ve been toying with the idea of starting up my own esk8 parts shop since this whole COVID business started and I found out that I didn’t have to go to work anymore . So for the past couple months, I have been designing said parts, starting with a gear-drive.
The case will be fully aluminum. I have a Trampa truck mount modelled and will work on the Matrix II mounts now. The drive angle will be 3-position adjustable.
The gears will be mod1.5, and have several options ranging from 55/10 (5.5:1), 55/11 (5:1), and 55:12 (4.58:1)
I was initially going to make mod2 metal/plastic gears, but I’ve noticed that vendors using this setup tend to receive a lot of backlash (see what I did there?). So the plan is to go with steel on steel herringbone gears. I really like the idea of herringbone because we can avoid those nasty side-thrust forces, while also gaining the benefits of helical gears…
I am currently looking at suppliers for the herringbone gears, but @moon is right, they are crazy expensive . So I would really like to determine how many people are really into the idea of herringbone gears, or else I may switch to helical or spur.
I would like to try to keep the price (with herringbone gears) somewhere below $600usd, but it would depend on initial interest.
I will be ordering test samples soon, so I would will probably begin testing in a month when they arrive, and then if there is interest, I would order more in the following weeks for sale.
