DD4H, I think the name could be Mini Bullet, thoughts? This little tool will change my racing! Thank you!

Man, I finally have the press perfect and you come out with this!?! ; )
From what I see, the drill bit is kept straight because of a significant distance in the jig. Obviously it looks awesome. A couple questions since I am looking at this on my phone (trying to do my day/night/on call job)--
Is the distance the bit is in the jig longer than the tool everyone says is bad from derby works? It looked like you did not have to be super steady when drilling.
Do you adjust height with shims so that you can drill at different heights? I would buy machines plat shims of combination heights if it was offered.
Is there a concern over time and use that the jig will lose fidelity with repeated drilling scuffing and deforming the jig? If it is expendable, any idea of lifespan?
It looked like you gave John a great suggestion for hash marks on the jig on top. Do you know if he can machine those for use with the CNC which is likely to be more accurate than us?
How much and when can I get one yesterday?
Are the other holes 0 degree vs 3 degrees? You may have said that but I was multitasking.
How much are then and when can I get one?
Seriously, how much and when? ; ) ( rule of threes for comedy)

John will be selling them very soon. They drill at 3 degrees and 0 degrees. The jig is not adjustable. It drilled the best drill I have ever had.

If the bushings are hardened steel, then I should imagine you should get a lifetime's worth of drills from them.
Not sure you will get a lifetime as those bushing will eventually give out, but not for a while with carbide bits.Vitamin K said:
Thanks for the answers. What do you think of the idea for machined shims that could be placed on the floor of the jig. While I have some shims, they are not that wide and I am concerned anything less than the width could cause the wooden blank to be angled. Of course, for my idea th work, the holes in the jig would have to start higher than 1/8".
All info will be given once I have the stock in hand. I will say this the tool was made to very high tolerances to help meet the new standards and that means it cost me a pretty penny to have them made. With a tool like this any corners cut will make it useless. Be prepared for a stiff price...
Well I am a sucker for new tools and I always stress out when it comes to drilling axle holes. You can put me down for one. If Bulldog says it is that great then cost isn't a factor. Actually if Bulldog told me tomorrow was Easter, I would be coloring my eggs tonight!DerbyDad4Hire said:
Great video Bulldog!
If one were to walk into the majority of manufacturing plants out there, you would see a lot of these types of fixtures. They are reliable and accurate. The drill bushings can be bought at Carr Lane. So if they do wear out, you can replace them.
Although it only has bushings for 0 and 3 degree respectfully drill holes. I'm sure one could do the math to figure out what size pin would be needed to achieve 1 degrees of cant.
I like it. Easy to use, takes the guess work out of things.
If i knew the market was big enough. I'd buy a machine from work to do this. This fixture could be made with 3 tools. 1" endmill, drill for bushing, and boring tool or reamer for bushing.
John is right, accuracy drives cost up. If you had people to buy 500 of them the price would go way down. But if I make 25 at a time, someone has to soak that cost.
John, if you ever want to break into buying a CNC machine to make your stuff. I'll program it for free. Bad thing is the initial cost of the machine and tooling.

You could buy shim stock in a sheet and cut it to size?
This is a 10"x20" size as an example, many sizes and thicknesses are available: http://www.use-enco.com/1/1/31-sheet-black-plastic-shim-stock-327-6824.html

Hahaha She is working overtime as it is to support my habits. I am .03 off from the leaders in my first race. That is going to cost a lot in building and testing to cover that ground. I have the old DW jig I will sell you cheap! lol That will help me to catch you if you use it properly.
