Gear fabricating
« on: January 06, 2019, 11:24:56 am »
Has anyone had a gear (or gears) fabricated in North America? I need one for my gearbox.

 No but it's as easy as "down under" so if you run into trouble let me know as I can probably help you.

Thanks Brent, I'll let you know. I haven't heard back from Ellis in the UK so I'm "reaching out" closer to home first....just in case. Plus, this gearbox is all one-off stuff and it scares the #$%* out of me shipping anywhere, let alone across the world!!

My neighbor runs a machine shop that produces, among other things, blanks for gears. I sometimes help run parts for him if he gets behind. The shop two doors down then takes the blanks and cuts the teeth and/or splines, and from there they are sent out for heat treating.
One-off parts all always expensive!!! Reverse-engineering a part adds to the expense, compared to working from a toleranced blueprint.

This was a gear that I had made with one extra tooth. Reverse engineering probably required.

I see there is a chunk missing out of the tooth at the top. Was the mating gear also modified? The main shape of the gear and the dogs would be done at Mike's shop, before moving on to the gear/spline shop.

bwaller, unfortunately I doubt you will hear from Ellis anytime soon. He had a really bad crash at the last Aintree meeting of the season. Sad to say he is very seriously injured with life changing injuries.
I'm only old on the outside.

Brent, to add to what Tony has just posted, sad news about Ellis, no more gearboxes due to a bad crash he had while racing at Aintree 15th Sep.
He sustained a spinal injury and can no longer walk according to the lady I spoke to, guessing it was his wife.
Sorry for the bad news my friend.

That is horrible news, poor Ellis. He is such a great guy, I hate hearing this.

Wow, that is awful news.  Not sure how to say this without sounding superficial, but wishing better days ahead for Ellis.
