So I have almost no experience drilling out/tapping rusty bolts so I've been doing a lot of reading and making a mental parts list. I just need to know if I'm going in the right direction. This is my DD and more than one weekend's down time means I could lose my job or fail college. I'm fixing one small issue at a time so I don't leave myself FUBARed without a car.
Problem 1) Broken flush crossmember bolt (1)
Problem 1) Broken flush crossmember bolt (1)
- A - Grind flat with Dremel.
- B - Center punch
- C - Anneal
- Bought small torch (heat wrench)
- Use cool smoky flame to soften bolt
- Need to buy fire extinguisher
- D - Drill
- Bought a 1/2" HD Milwaukee drill
- Need to buy quality metal drill bits
- Need to buy 7/16" tap
- Work in increasing sizes until I reach correct size bit
- A - I found this: http://www.boltdepot.com/fastener-information/US-Tap-Drill-Size.aspx
- Will I need 7/16"-14 or 7/16"-20?
- I'm assuming one is course and one if fine, and I'm guessing I just need the course tap.
- B - Drill bits:
- I need a left-handed drill bit correct?
- I am looking for HSS drill bits correct?
- What size bolt am I looking for at the fastener shop? 2" long?
- Grade 8 - flanged head correct?
