OUCH!!!! That's 19+ inches of stock, and at 800 R's that would be moving! That is a nightmare.

I chucked this piece in the lathe and really laid into the wrench to ensure the jaws were tight. Then I stood to the side when I spun it up, but even then it was only at 320 RPM and I only had about 1" hanging out of the jaws. I don't even want to think about the amount of energy in the piece you had come loose. But, I'm sure glad you survived.

 

Thanks Gary - me too

 

Got a bit more work done on the spacer today. Bored the pilot bearing pocket out, and got a good start on reducing the 4.000" diameter of the rear part of the spacer down to the 1.749" it needs to be. Boy, is that a lot of metal to take out! Swarf all over the place. Maybe tomorrow I can get the rear part down to about .020" over the finished diameter, leaving the final cut until it is mounted on the faux crankshaft hub.

I've attached two pic's, one before I started and the other after.

 

More work on the spacer today:

1. The first shot is of the rear of the spacer. It is now done to rough dimensions, meaning .020" oversized so it can be turned down to size when mated to the faux hub. However, the length of the pilot on this side is .100" longer and the pilot bearing pocket is, therefore, .100" deeper since I know I'm going to have to turn the face down .020" and wanted to be sure I had enough material.
2. The second shot is with the stock reversed in the lathe and is before facing it and turning it to the proper diameter.
3. Third is turned to the proper diameter plus .020" and the thickness reduced to .320", meaning .020" over the finished size.
4. Last shot is of the recess for the crankshaft's pilot. I got the recess to 1.375" in diameter, but still have to get it out to 1.750" to accept the pilot. But, it is .220" deep, which works with the pilot as it is .219" deep.

Maybe tomorrow I'll get to finish the pilot recess, take the spacer out of the lathe, and start on the faux hub.

 

Way to go Dude!!
Looks like it is coming along pretty good.
I'm envious of you and your knowledge of that equipment.
Keep up the OUTSTANDING work...Trav..

 

Thanks! But, my knowledge is limited - I took a one semester course on the lathe and one on the mill at a community college about 6 years ago. At almost 60 when I took it, I can honestly say it was the most fun I've ever had in a classroom.

But, I was there for a different reason than most, if not all, of the others - I wanted to learn and they needed to take the class to graduate. I'll never forget one of the guys coming up after the final to ask what I put on a certain question. When I told him he asked how I knew that, and I said "It is in the book". He said "You read the book???" I didn't have the heart to tell him that I skimmed the book the night I took it home, that I read the section at the start of the course, and I read the appropriate chapter each week.

 

Taught an ole dog some new tricks.
I am looking into a course for mig and tig welding.
I have a mig(Clarke,old) but works good.
I have a Harbor Freight brand plasma cutter but it has worked great.
I really enjoy using them and figured a little extra knowledge with my limited experience will help.
Anyway,people our age will actually learn better than SOME of the younger gen. Later, Trav...

 

I actually was thinking about a welding class myself. We went into Owasso yesterday for dinner to celebrate our 43rd wedding anniversary, and on the way home saw that the new Tulsa Tech building is almost done. Hmmm, wonder if I can get a course in welding?

I have a Century MIG and a plasma cutter, but don't remember the brand. I've built my engine stand, shop crane, and several other things, but it has been a while and I need to build the rotisserie to put the bed and cab on when I'm doing the body work. I have all the steel cut, so could start putting it together when I get the ZF and the engine installed

 

I want your old C6 Gary.

I need to take a welding class, especially if I keep ending up with all this scrap sheet metal. I have plenty of patches that I need to make.

 

You may have to fight Bruno for the C6. It is sorta spoken for, maybe, kinda.

As for the welding, my thinking is that it takes better welding to do body patches than it does to do the structural work I've done, like building the shop crane/engine hoist. On the latter I used up bunches of "mistake eradicators" - aka 4" flap wheels.



As for the spacer, I got the front done, meaning the pilot pocket that goes on the crank. Attached are pictures:

1. Front view of spacer with the pilot pocket finished. ID is 1.752", but it is a pretty good fit on the crank.
2. Rear of spacer, still sporting its extra .020" on all dimensions for true-up.
3. Crank and pilot, replete with layout dye to check for high spots.
4. The spacer on the crank.

Tomorrow I may get to cut the stock for the faux hub and start turning it down. For my benefit, the process will be to:

1. Face it so the face is true to the chuck
2. Center-drill it
3. Drill it through with the tap drill for 1/2-13
4. Tap it 1/2-13
5. Face it from the outside and leave the center ~1.775 OD and about .220" tall.
6. Turn the center to 1.750"
7. Face from the inside to clean it up.
8. Mount the spacer using a bolt in the center
9. Turn the rear pilot down to 1.749
10. Face it down to .300" thick
11. Check height of pilot and face it down to dimension
12. Chamfer all corners

 

I may know of some interior panels that Bruno would love to get his hands on, but could be used as a distraction first.

 

Good job, Gary

 

What he said.

 

The Rep Police have me locked up in solitary Gary.

 

I'm not sure Bruno needs any distraction right now. He's got parts at my shop that he started working on over a month ago and hasn't been back. I hope he's busy at work.

Thanks

Thanks

Thanks

Coming from you guys that's better than reps.

Not sure how much I'll get done tomorrow. We have company coming in and I have some things to clean in the house - I've already been advised. And, I need to clean the shop a bit. But, maybe I'll get some done.
