drill out 3/16 props to 1/4"?

[kevinpratt823]

Has anybody tried drilling out 3/16 props for 1/4" shafts?

Why dont you just use a 1/4 shaft stepped down to 3/16. You can buy one here at OSE.Its nearly impossible to drill out a prop perfectly straight.

I tried and it's fruitless.

You'll need to chuck it in a lathe & ream it out to 1/4". But if there's not enough 'meat' left in the hub you could throw a blade at full noise. Not pretty.

I already got a reg 1/4" shaft, I'm going to use it with a couple 1/4" props I just ordered, and down the road may switch to a step down shaft if those props don't get me where I want to be. I figured somebody has already tried drilling them out and I just wanted to hear the results, pretty much what I expected.

It's a pain in the butt, and it's almost impossible to get it perfectly straight.

I looked to buy a set of 1/4 shafts with the step dwon and found that I can't find the right turn shaft. Where can I find counter rotating shafts with the step down. I have stainless props and they are much thinner in the shaft area. I think that I will have mine milled down and save me the trouble of looking.

What size motor are you using . Most good quality 3/16 flex shafts will take a ton of torque before you see any trouble .

Mine is a DF Sniper 45" with a Castle 2028.

[carlcisneros]

the motors are Hor racing SSS5694 1200 kv on 6s and also 8s twin. And the props are the Prop Shop 5517/3 stainless props.

I might have the stepped down 3/16 rev shafts e mail me and I will look [email protected] thanks chris PS I have some 5517/3 SS props in 1/4" in stock !

Well that is something that I wished I would have known before I had made the buy on ebay. I had a friend turn down my shafts to 3/16 to make my props work. he is a good friend so he only charged me 5.00. Coffee money. I meet with him in the mornings for coffee when I can.

I worked the props quite abit. I removed almost half of the metal from the back side of the blades. I like stainless for this reason. I order the 3/16 drive dogs and have the props to balance still. but there coming along. I will keep you in mine for my next props though. Thx!
