Question on Drilling Bevel Shafts, Tranny Shafts

[dezrik]

I *tryed* to drill a hole in my tlt bevel shafts and failed horribly, Any help would be great, I only have a Drill press (delta smaller one), I also want to drill a hole on my axial trans as well but dont want to screw it up

Use a center punch to get a tiny dent were the center is, then the bit will fall into that hole and be directly in the middle.

You need V-blocks to hold the material since it is round.

^^start here.^^

drill a very small hole... and get progressively larger until you have the size you want. Key here is take your time, if you get off center there really is no turning back.

I put mine in a vise. Used a punch to mark the center. Drilled it out with my cordless drill. Starting with the smallest bit and working my way up. I felt it was more accurate than my drill press because of the run out on my press... it's just a cheapy.

Ill give it a try, ruined a set of bevel shafts already, ill try a cordless drill instead of the drill press

[TwistedCreations]

No, do not try the cordless drill... if you have the drill press, use that..change speed to the slowest speed possible and use good bits(add oil as needed)

[af_juicy]

The truth is the Press is your best bet just slow it down, and use good high speed steal bits. Not general purpose bit and like TC said make sure to keep it oiled. The oil will keep you bit from over heating. Heat will kill you bits. I have used just about anykind of liquid possible to drill into metal water, pea, oil and ever electra clean. You do what you got to do when you are offshore and you need to drill a hole in a peice of metal

I would use the drill press. The problem with the "cheapies" is that they don't go slow enough. Set the drill press to the slowest speed, clamp shaft in a vice and center punch. Or better yet try and find a center drill, Machine shops use these to tool centers for lathe work. They are a large bit with a small point(no deflection) If you cant get one, use a small bit and "peck" at it untill you get a spot started.....don't just power through.

What kind of vice are you guys talking about? One thing I've been trying to figure out is how to secure parts from moving when using my press. Also, what are v blocks? Pics would be good too!
Thanks,

I prefer the cordless, I just feel as though I have better control. The tiny stubs are usually hard to clamp in a vice and center under the press.

V- block vise?

I'd get a new vice with V grooves cut in it. V-blocks are a pain to use for smaller stock. If I go on long trips with R/C's I usually bring the vice with if I have to fab away from home.

I've got one of these works perfect for holding rounds at 180 or 90.

Also bought one of these, I haven't used it yet. But, the idea seems like it would be a real help.

Thanks Mnster. I've never heard of a v-block vise. I found something similar to what you posted and will probably get one soon. That centering tool is pretty interesting, let me know if helps make a difference.
