Way to go, Luke!
Looks shiny!
Your plan for the wrenches sounds awesome – best combo yet!
As I mentioned earlier, if those wrench designs work out, it would be cool to produce extras, just for sale by themselves. Greg has been incommunicado for a while, but when he gets back, maybe we can see if the ASCA could benefit from a case or two of the 9/16” + 1/2” wrenches.
Stainless definitely seems like the right choice, for long-term function as well as aesthetics. Any word on the DA collets and the material, Aric? I can totally see how corrosion problems could arise if the holder were non-stainless. If the collet is also non-stainless, then lack of maintenance and moisture could cause the collet and holder to seize up. Or worse, the drill bit too!
I couldn’t find any specs on the Kennametal website concerning collet material. But here’s a good link with a chart on DA collet sizes and part numbers:

One idea, although it may be too late for production on the Hurricane…
How about putting a light knurling around the shank of the drill holder where the grip sits. This would help with glue adhesion on the shank, as well as create a textured surface for the grip to stick to. Yeah? No? I wonder if it might help with keeping the grip in place over time.
Hey Aric, how about some serious knurling on the aluminum sleeve of your design for the grip to stick to? If tolerances were tight enough (sleeve/grip) you might be able to get away without using glue. Who knows… just some more thoughts.
Oh… BTW… did someone say something about a RED grip on the Hurricane??? …RACEY!!!
Carry on!

Minerals,
I plan on having 300 of each wrench made.... If I could get my scanner to work I would throw some pics up here... I should have an extra 50 or so sets to start out with...I can get some more made once I recoup some cash... Great idea!
I so far think I have secured 22 grips in black...I know the outfit made them in red and black originially.... Hopefully they will whip us up some!
Knurling would have been a good idea for sure....I am willing to bet it my be difficult after heat treatment, but I can give it a whirl in my shop on the proto.
Should be racey! Drill is high speed!
Then you can find it in the talus.

I agree....would be tragic! but it would better your chances of finding it!

No luck finding stainless ones yet, and given that the machinist forum I asked about it on yielded no leads I suspect there is no such animal and the ones on the Hurricane are actually not stainless. Given that we haven't seen any reports here in this thread about non-stainless collets being a problem on the Hurricane I suspect that a bit of care and a touch of oil would be sufficient to keep things happy.
Hey Aric, how about some serious knurling on the aluminum sleeve of your design for the grip to stick to?
I had thought about doing that, but decided it would be quicker and easier to simply skip the finish cut and instead rough it to finished size (heavy feed with a pointed tool should leave quite a bit of texture). That said, putting a knurl on it wouldn't be too hard to do so let's revisit this if the rough cut proves insufficient.
Oh… BTW… did someone say something about a RED grip on the Hurricane??? …RACEY!!!
Huh. Never thought about colored grips. Apparently the ones I went with are available in black, red and white. Unfortunately I already ordered them, so you can have any color you like for your prototype, so long as it's black. :-)

Just a quick follow-up on the stainless collet thing... Consensus amongst people on my machining forum is that they don't exist. A good alternative was suggested though, which is to use through-coolant collets. Basically they're normal collets that have rubber molded in the slots to seal them so that machining coolant can be pumped through the center of the tool and not leak out the collet. Obviously not something we need to worry about here, but the rubber would do a fairly good job of preventing water from getting in so definitely something to look into. Looks like they're available in both ER and DA, so possibly something to consider for the Hurricanes as well.
Then again, there haven't been problems reported with existing Hurricane collets so perhaps this is a solution looking for a problem.

Luke,
Do you have an approximate price and a list where you sign up for one of these beauties?
Cheers

Luke, I would certainly be interested.
I know I have been gone awhile, but 218 posts?
How'd I miss this one? Great project,
Thor

John/ Thor,
Sounds good. So far there is no official list as of yet....I just wanted to see how many people were into having one...
I am having them made now and the 2 main parts should be here on 2-7-11.
I will start building them then. I do have a proto that should arrive next week, and am going to try a couple off different grips/ leash options out. Also going to make sure that everything was done right and hopefully approve 249 more.
Still not close to running out of them so there is no worries about not getting one @ this point if interested.
I think that there is enough people that would want one to have another batch made so I pulled the trigger and went for it.
As far as costs...When I first posted I was thinking between 100-120 each for everything (wrenches, collet, drill, blowtube, etc...just how the originals came.)
They are going most likely to be around $120ish. I am doing a couple of things different ( Custom wrenches) and sourcing the grips and collets that will still have a impact on the final price.
Still trying to work out processing fees (for credit cards) and shipping as well. I will work more on this after I get a couple more quotes back.
I am going to start a new thread when thee proto arrives showing the build, testing and will work on a master list for those who want one.
Thanks,
Luke
Edit:
Aric, Can I have my proto with Black grips :)

Update for Luke & Minerals-
I now understand why they charge so much for ER collet nuts... They're a royal PITA to make! Getting the angle the front of the collet bears on isn't too bad, but getting the angle plus the right depth plus a good finish is tricky (probably not bad on a CNC lathe, but I don't have one... :-( ).
Anyay, I finally got the tooling for it properly sorted out this morning, so all that's left is a bit of time on the mill, heat treating and assembly. Maybe have them ready to go next week sometime? Will post pics when they're ready.
-aric.

I'd be interested in the wrench by itself!

My "new" (old but bought recently with a Hurricane) A5 wrench is cracked as well, I wouldn't have used it at all except that Minerals told me his has been cracked for years and hasn't broken yet...

Sounds great Guys! I am still waiting on a quote back from the stamping outfit....We have been working on getting the thickness correct for the amount of torque required. I will have 50 extra sets out of this run.
Ordered up the Stainless Steel Cable today and the grips as well. They will be black and just like the ones found on the original drill.
We are closer to 50 or so wanted now!
@ Aric- I hear you on the collet nut for ER 16's...Props on doing it...I gave up and just bought one.
Spread the word!

I kinda had to make it, Luke... The only low-profile nuts I could find were those Craftsman Industries ones I linked earlier, which are $25 a pop and metric. So between not being able to thread Metric on my lathe (I'm missing the pair of gears that converts it) and not wanting to spend that much on a 3/4" long piece of steel, making it was the only option.
What I ended up doing was using a 1/2" diameter 60 deg dovetail cutter as an internal form tool, which isn't good for the tool (not enough room for clearing the chips) but seemed to work OK if babied. Conveniently doing it this way both set the proper angle by virtue of the shape of the tool and left a nice finish since it was taking a cut across the entire face rather than a point feeding across it. That said, I think the "right" way to do it would be a T-style boring bar with a bit of negative end rake, but the one I tried didn't have enough relief on the insert for the 1/2" section of the taper and rubbed. Unfortunately the box didn't say whether the inserts were TPMH (11 deg relief) or TCMT (7 deg relief), so I'll have to measure them at some point. That said, it would probably be better to simply calculate the minimum amount relief required, as I suspect it'll more than is available on a standard insert.
Anyway...
-a.
EDIT- Crap. They're TPMH and the only larger relief I can find is TDMH, which only steps it up to 15 deg. Guess I'll be sticking with the dovetail cutter workaround for the time being. :-(
