Castle 1717

[bruce750i]

The shaft size is also wrong on the chart for the 1717 Somehow they conveniently missed this error, it's 6.0mm! Anyway here are some pics.

Motors look reallll nice, my 1800kver should be coming any day now. BTW sorry about your 1717.

3 motors!!! Santa has been good.

Hmmmm............I wonder if Castle will start carrying the pinions for the 6mm shaft size?

Nobody offers them at a fair price as of yet.

If you use a plastic spur then SDP-SI has 12, 14, 15, 18, 20 tooth 6mm bore Mod1 pinions in carbon steel for $10-18 depending on the gear. These could possibly be hardened and used with steel spur gears...

How much of a PITA would it be to drill out one of Mike's pinions? What do machine shops usually charge to have a shaft turned down?

The SDPI gears are made from 12L14 - can be case hardened (at home even with some kasinite and a torch). It wouldn't be worth trying to ream/bore one of my pinions - they are through hardened and are too hard - it would require a stiff, beefy lathe, an expensive tool and coolant to even make a go at it.

Wowsers, Big diesel bastards they are ! Sweet.

Take both peices(pinion/motor shaft) in and see what they say which would be easier/cheaper. Keep us posted if you decide to do this !

I'm thinking it would be easiest to have the shaft turned down. It can be done at home if you're careful but I'm worried about getting the shaft too hot, gotta stop to let it cool often.

Drill press,emory cloth,lotsa beer for patience,Repeated oil dips.
Shouldn't take to long for a 1 mm ?

Whoa, just read that, 6mm shaft?

Now I couldn't use it even if I did have it....which I don't. No word on mine yet.

Drill press might be a bit difficult, I was thinking of rigging up something to get the motor spinning at partial throttle and then using either some really good sand paper or maybe carefully use my Dremel to take off little bits at a time.

Just checked my credit card online and I was charged for my order today, so its is on the way, just didn't get an email....

There is a prob though - they charged me full price for the 1717 even though I ordered on 11/30. Guess I'll have to get that straightened out tomorrow on the phone.

Then it gets to sit while I fugure out what to do about finding 6mm pinions...

Hmm, thats a bugger. I have a feeling CC will be getting a piece of my mind if the 1717 shows up with a 6mm shaft. How hard is it to proof read your website? Seems like we do it fairly frequently (check this thread for examples...). I will have to contact CC about sending me a modded shaft to replace the 6mm unit... Of they can send me about 50 mod 1 6mm bore pinion gears to replace my stock...

I had a kb45 turned down once, but it was not ground for a flat area yet. I had to make up a pvc collar as the machinist did not want to magnitize his lathe with the rotor magnet. A real PITA, spent about 1 hr at lowes getting the correct sizes of pvc rounded up. Then he had to turn it to fit the rotor to clamp it properly. A grinding stone and partial throttle should work, but I really do not want to do that to a 200 dollar motor.
