Machine Shop in Lower Mainland - Gun Drilling

[Greg_B]

Hi all.

Does anyone know of a machine shop that would gun drill a few birfields to supplied specs?

For the use my 80 sees (want to maintain AWD) I don't think I need or want Chromoly, which seem to be the only option when ordering gun drilled birfs.

I don't have the replacement birfs yet...just put'n it out there.

Im sure Mr sas will chime in greg. I like your thinking.

crappppp. how did i get involved

honeslty i dont know who can gun drill your birf axle but why do you want to anyway???

its already quite a small part and the weight saving is not that significant.

generaly you gundrill the bigger solid axles. say 2" or more. for example overson offers this option for their axles but there is much more material there. toy parts are sort of beefed up atv parts.

unless there is something we dont know.

This is not a good idea greg, coming from a machinist when rcv or whomever make those birfs they drill and tap prior to heat treat. after they are heat treated they are hardened with a soft core you do not wanna remove the soft core and drilling that long after hardening will be a bitch.

If you wanna give it a go I'll call around some small shops we deal with that do small things, from what that other thread said basicallyonly the bell is hardened so a 6mm drill will not bug the strength in my eyes.

You going to put the PRV in the inspection port?

Thanks for all the replies everyone.

Sas, the intent (I'm getting older and lazy) is to supply hi moly based grease right where it is needed, at regular service intervals. The mines apparently have been doing it for years for the Toys that work in those environments, with the instruction to give 5 pumps of grease every start of shift. This is in Canada and Oz. Someone had some done back east IIRC, but that shop had a change of management and does not do them now. If I can get some regular new birfs done local (once I total the birf cost with the price check of gun drilling here vs buying a set from Oz) I will be closer to making a decision.

Glenn, yes. Have to price out current cost from http://gearingdynamics.com.au/Greaseable-CV-Joint-for-Toyota-Landcruiser for the PRV and Birfs - separate and together. Or do something myself.

Brad, sure. It's in the exploratory phase as detailed above, so would not put a lot of effort into it but on your rounds and if inclined..sure, thanks.

Maybe more people will want to get a set done as well?

oh i see. i thought you are trying to drill the inner for weigh savings. its actualy prety nice idea as long as you dont have locking hubs.


wrenchmonkey can you not just drill a small 1/8 hole. you future it would not take much if you take your time on a lathe.

Hi ,

I have a large lathe in my shop and would be happy to help out as will want to be doing this to my rig as well...

Cheers

I'd never heard of this. How much does this cost? Would be interesting to add it to maintenance routine and
see how benefits long term.

 

[HZJ73]

I'm not sure how much a machine shop would charge for this, I was just willing to have a look and help a fellow out...
I know it's not cheap to buy them!

Hi Bill.

Thanks for the offer. Where are you located?

It will likely be a while before I am ready. When are you thinking of doing yours? I have a spare 80 locking front axle which I will be taking the birfields out of. Then gun drill and considering sending to http://www.cvjreman.com/ for a complete rebuild. Or reverse order. Folks in the southern USA are giving good feedback on CVJ. For what I'm using the 80 for, this should be just fine.

Unless someone is going part time...then probably best to go http://www.rcvperformance.com/categories.aspx?catID=RCVP_TOYOTA_CV_AXLES

I've resisted so far...https://forum.ih8mud.com/threads/how-do-you-like-your-part-time-conversion.865853/

Hi Greg, I'm in Surrey and I getting my new truck on Monday and this is one of the things i would like to do to it just for ease of maintenance.
I haven't actually seen one of these Birfs apart yet but was hoping to be able to drill starting with a stub drill move to a jobbers length then onto a long drill as it would be rather expensive to set up for gun drilling. I should get a broken one to try it out on first... Send me a private message when your ready and see how I've made out.
Cheers
Bill
