Reborn56 and I have been trying to come up with some sort of way to do this. The problem is multiple things. A 1/2" npt fitting requires a 45/64" drill bit and they only come in 1/2" shanks. Length wise, the shortest one we can find is 6" long or 5" after we cut down. All of the right angle drill adapters I've found only take 3/8" shanks. We have a good right angle drill but its 5" deep itself and there is only 8 3/4" clearance from the motor to the frame.... I've done some searching and found that some people have done it with a hand drill. UR uses a Snap on Blue Point right angle tool that we think is no longer made.

I'd rather not use a Uni-bit, drill at an angle, pull the motor or god forbid use a Dremel

Any body have any other ideas???

Thanks
Jeff

 

It's very easy...........Just use a pin vise to hold a 1/8th inch drill bit and drill a hole by hand where you want the return. Then use a larger T-vise to hold your larger drill bit and once again drill it by hand. The aluminum is pretty soft and doesn't take much to drill. This is how I did it.

P.S. Machinists have a lot of pin vises or drill bit vises.

 

I used a Craftsman right angle drill and cut the bit shank down as much as I could. However, my trick was that I changed the chunk on my right angle drill to accept 1/2 drill bits :-)

 

How long was the Bit you were using?
Before you cut it and after you cut it?

I have no idea what a T vise is but i will find out
Thanks bro

I have no idea as I didnt measure.
I can only measure the length after I cut it at this point if you want me to find out.
But it was just enough for me to be able to squeeze the right angle drill in there. I mean it's tight but I was able to get the drill straight to drill a nice hole.

 

Cut back fluted end of drill and resharpen it.

 

i just used a right angle drill and unibit and took my time. threaded the hole and ran a shortened fitting in there with some honda bond.

 

yea thats what i suggested to Jeff, i have a unibit but i wanna use the right bit and not have to worry about it.
