silver bullet

[Kinser Racing]

I'm not exactly positive on what I'm seeing. What happened? A shot just a bit further back would help.

 

[GravityX]

Ahh..... What in the world happened here? Looks dire.

Dang...I should have asked here first!

 

[ChrisF]

Those are two different views of the same area.
Let me see if this shows it better;

 

[GravityX]

Either way... Ouchie!!!

 

[GravityX]

Better yet... How did this happen? Were you trying to install an axle then remove?

 

[Obsessedderbydad]

Rear axle hole? What happened?

 

[B_Regal Racing]

Looks like you need the Orkin Man...

You might be able to use the CA / baking soda trick to salvage it if you think you can redrill. Thoughts? I saw GravX talking about he trick a few weeks back and it worked like a charm to sure up some fenders.

 

[derbychip]

went ahead and drilled cut another, wasnt sure if i felt ok with it as it was, would always wonder if that held the car back some

what you think?

Well...you know how some folk use an axle to "relax" a hole that's a bit too tight? Instead of an 0.085 or so axle, I decided to go a little larger to speed up the process...

...that and not leaving enough support material, and some bad grain...and "pop went the weasel"! Now where did John say he got those reamers in ten thou increments?

I already went ahead and fixed it with epoxy using the steps I outlined above. I'm pretty comfortable with epoxy (as well as duct tape and bailing wire), but not so much with CA. I think the repairs went well, because the car has posted some pretty good times post fixin'. You might not know this about me, but I invented the term "Fill and Drill". The right type of epoxy is the key.

Looks good, DC. Now make a small hole down your axle line at the end of the axles to let the air out when you push the axles in.

I definitely wasn't questioning it. It just made me think, that's a good thing. That's my thinking emoticon. /images/boards/smilies/smile.gif

/images/boards/smilies/thumb.gif I didn't know I ever made you think. But I needed not take credit either. /images/boards/smilies/thumb.gif

You can get some of those reamers here. Just select the size you want in the left hand column to reduce the amount of choices.

that used to be a trick that the better bowlers used for their thumb holes. Had the pro shop drill a very small vent hole, starting next to the thumb hole and penetrated at the bottom of the thumb hole.

Let you have a tighter fit for your thumb, and it would still release and not get stuck because of the suction. Kind of the same concept as the hole for the axles, but in reverse.

When I have had some cracking like that I will put a small amount of wood putty over the area. If it bleeds into the axle hole its easy to clean out with a pin vise. Seems to work for me.

Thank you GravityX. I'm about to drop a chunk with MC for misc tooling to substitute for my lack of brains and skill.

Thank you for the suggestion, Dr.T. Unfortunately the wood putty that I have available here does not provide structural confidence. It gets pretty crumbly. Is there a brand I should look at? For now, I like the range of properties I have available with the various epoxies on hand (Plastic-weld, Devcon F, Devcon A, Steelbed, Marine-Tex etc.)

I like the epoxy idea. It seems strongest as long as you can get a good release off the axle.

Bondo would be good for something in between putty and epoxy.

Bondo does not stick to Seran wrap.

Perhaps an undersized axle with some Seran wrap around it to keep the Bondo at bay.

Just thinking aloud

Joe,

If you're going that direction use Dolphin Glaze it's the polyester filler they use on top of bondo. I used to use it to cover lead weight..
