Your pin  vise raised red flags for me. It’s too big and heavy, and the ball anchors it in your palm, so you don’t have fine fingertip control. I recommend a couple of Starrett sizes. I’m also using an old Ehrlinger slip ring pin vise that was my ‘go to’ for small bits until the chuck wore down so that it won’t hold bits smaller than #76. I ordered a replacement two years ago, but the chuck was acentric, so I sent it back. I tried again a year later with the same result. Apparently Swiss precision has slipped since I bought the first one.


Look at the pin vise posts on resincarbuilders group for other recommendations. Bottom line, you fingers should control the bit, not the palm of your hand. No wonder you break bits.

Thanks for all the comments about my grab iron hole drilling. My tools  and drilling setup are shown below.

My only explanation is that I might have gotten a bad batch of Gyros #78 drill bits.  I have never had such bad results as this before. I have been drilling grab iron holes since the 1980's. 
They last 4 were drilled with a #76 bit which did not break after 10/12 twists.  Note that I am using a Mascot twist drill with non rotating wood handle. Boelube (from Boeing development) was used on every new bit and when cleared. The holes and bits were cleared of plastic regularly as I drilled.  I have not had problems with Gyros bits before and found them to last often beyond one project.  I am now done with the 72 holes. The grab irons have been inserted and secured with Plasti-Zap Medium CA from behind. I will probably let primer and paint coats fill the gaps in the grab iron holes. 

 The next challenge is cutting the bolt heads off 72 Grandt Line 3/4 nut to glue above the grab irons.  Unfortunately my pipette glue applicator is clogged. Soaking in IPA now.

And I usually drink Irish whiskey not Scotch (unless I happen on an excellent single malt at an affordable price.)

My plan for the future is only build kits of more modern cars that have ladders not grab irons for reaching the car roof.
