Re: pic: WCP: AL Gears?
Do you anticipate being able to support the potential demand?
|
Re: pic: WCP: AL Gears?
Will you be selling pre-lightened versions of the gears? (Aluminum is light; holes are lighter!)
Just curious: are they 7075-T6, -T7 or something else? Is there much wear of the dog mating surfaces after several hundred hard (e.g. pneumatic) shifts? I'm curious if it rounds off the edges on the aluminum dog gears. (Even if it does, it will likely be no trouble at all for most customers.) |

Oh boy, I've been waiting for COTS dog gear replacements...
Time to get that 3/8" hex broach. |
Re: pic: WCP: AL Gears?
These look awesome! Do I see correctly that these include the little nub around the hole to keep them away from bearings? The size selection will be nice too. I'm guessing mostly 3/8" hex on most of these? Are 35/45/48/60 only available with the dog cutout, or can they have keyed hole (hex or otherwise) as well? Can't wait to see these available!

We shift with a 7075 dog on 4140/1144 steel gears with no wear whatsoever on the dog itself. In 07 we had a 7075 dog on hard anodized 7075 gears and saw no wear on either the dog or dog gear. |

Only took you 3 years, RC.
I kid, I kid. <3 |

If others did/do notice what they would consider excessive wear, I would also ask that they objectively determine if it is causing any excessive backlash, efficiency changes, or is causing further wear more rapidly. RC, a question for you. Are these gears cut with a modified addendum and dedendum to account for the build-up of the type III anodize? |

I feel a lot better after talking to AM, I have everything ready to go in order to ship these guys and I believe I have made enough for this year. First year in, so I don't know how much demand there truly will be. But provisions have been made to make more gears during season if needed. The place I work at has an SL-30 lathe with a bar feed that normally runs lights out, as long as the OD is under 3" I can have blanks ready next day for the hob guy/shipped over night via Ontrac.

All the gears are 7075-T6 and Cory/Travis are correct. The coating 1323/973 used last year wasn't that good, but the new coating is significantly better. It is similar to AM's 50T and when we used his 50T this year and last year for some high speed applications, that coating was very very good. Quote:
Current Lineup: 14T - CIM pinion - 3/8 Hex 15T - 3/8 Hex 28T - 3/8 Hex 30T - 3/8 Hex 35T - Dog Gear 45T - 3/8 Hex - 1/2 Hex - Dog Gear 48T - 1/2 Hex - Dog Gear 56T - 1/2 Hex (Cimple Box Gear) 60T - 3/8 Hex - 1/2 Hex - Dog Gear Quote:
I believe either you or Adam brought this up when we made our season gears last year. We did not do that last season, but this year after talking to the Ano/Gear place we have. -The ano place, Nituff says ano should be .001 penetration and .001 build up. Normal range of build up is .0008 to .0012 according to the rep. -The gear guy is compensating for that, I got a shop tour and talked to them about our application. They said they would cut a few gears, get them ano'd in house and then make sure it passes their QC, which is quite nice. -RC |
Re: pic: WCP: AL Gears?
Cool. Thanks for the info. Sounds like something we might have to consider this year.

Also, I'm not sure if RC has brought this up but, many of these gears will be drop in replacements for AM gears, so if you find yourself in need of an extra pound or two in the last week of build, keep WCP in mind. |
Re: pic: WCP: AL Gears?
Any idea what pricing is looking like?
