Porsche 550 Build: Rear Section Part 4

[@richardm.gramling1772]

Decades ago a wise professor once said "The mind can odsorbe as long as the rear can indure". You guys have a decent time line.

[@leebyrne2647]

I love the new format of the channel. Watching Wray go through all the steps has made this channel one of my personal favorites.

[@michaelmcmemory6532]

Great to watch this series and absorb the methodology and Patience in Practice!!

[@tedbauer7380]

Making real parts that fit with equipment that is attainable to the average person would be very helpful. Thank you for taking the time to make your videos.

[@paulwhiteman3625]

Thanks for today’s instalment, Wray. I’m looking forward to making a wire form buck for a Lotus 11.

[@RonCovell]

Thanks for another fabulous tutorial, Wray!

[@proshaper]

Thanks Ron, for watching.

[@LaredoHandyman]

I love how you turn the volume down during the noisy parts! great editing!

[@andysutherlandtaylor9012]

Lunch & a Wray vid made my day :)

[@GregsGarage]

It's always fun to see the panels take shape.

[@oldswedegarage1577]

Thank you Wray Incredibly interesting to see how you shape the metal And it's really fun to see your different English wheels

[@buck6604]

Thank your these videos. I like your ingenious ways of navigating through making complex panels using varying techniques, tools and combinations.

[@johnnymartines2118]

Very cool getting to all the methods.

[@SantiagogranadosR]

Thanks, following the whole process, really interested in both methods!

[@tomthompson7400]

A great video , the wheels Chris made are really nice , Ill go check his lights , he does seem to have a flair for design .

[@johngunn7087]

Excellent content- as usual !! Thanks, Wray.

[@andrewference1479]

I'm loving the quick fire vids. Any chance you'd make an example full surface buck one day and show how to hammer a panel on it?

[@jameshodgson9796]

Terrific series of videos. Could you comment on using 3003 vs 5052 aluminum?

[@proshaper]

3003 works easier that 5052 but they both can be annealed and then they work about the same.

[@dominosgarage]

Another great video

[@brett8090]

I'm very interested to see more about the "KZbin Wheel". Also, if this turns into yet another hobby I won't get too upset.

[@pouyan225]

I love the content, very informative.

[@kieren7763]

Thats gonna be a pretty tough panel by the time your done with all that shrinking I made my kids a half size captain America shield out of 1.6mm with about 20% shrink and it holds my whole body weight standing on top of it.

[@GC987]

Wray, Thanks so much for your instalments. I've become somewhat obsessed by the 550 and your work. Clearly this rear section is complex. It looks like doing the right hand rear section in 4 separate pieces would be a lot more straight forward. Do you happen to know if that's how the originals were done i.e. in 4 pieces or were they pressed/stamped or something else ? Good luck and looking forward to seeing your progress.

[@proshaper]

I will have an opportunity to see how many pieces were shaped when Wendler coachbuilding made the originals for Porsche. A friend has an original back body section.

[@GC987]

@@proshaper Thanks so much for replying. Now that would be some very interesting compare and contrast video - although it's somewhat academic on one level. Things are done differently for different reasons at different times. You're clearly forming those beautiful lines and ultimately that is much of what the average Joe will be aware of when it's finished.

[@motoputz3201]

more!

[@biggaralex]

I appreciate you Guys making the videos I learn something new every time I watch also just wondering when you're using A hammer or slapper on a wire buck should you be worried about distorting or warping the frame

[@proshaper]

That 1/4" diameter wire is incredibly strong. Sometimes a mig weld that wasn't done right will let go, and you just weld it up again. I don't make my panels using this method. In the video I'm showing you that it is possible. It can be very frustrating when developing a panel and you know that if you could just heat that little spot and shrink it right on the wireform it would be perfect. If you get to the point do it, it works very well and saves you a lot of grief.

[@strata99]

Love the videos and the information on metal shaping. How important is lower wheel radius? I seem to always over stretch my panels.

[@proshaper]

if your lower anvil makes any track mark other than a surface shine, either you have a anvil with too high of a crown or a poorly made anvil. You can prevent over stretching only by very close measurement of both radii. You measure with profile gauges one going East -West one going North -South.

[@strata99]

@@proshaper thank you for the advice I will keep working at it thank you!

[@dualhdx]

Hi Wray! I have to repair a Jaguar xk 120 aluminum hood and a trunk. How can I schrink it?, because is full of dents. Thanks a lot! Congrats for your job.

[@proshaper]

Go to my KZbin homepage kzbin.info and find the video I made on smoothing and shrinking aluminum. Also see my video series on making the left front nose section of the Porsche 550. I have 160 videos on my KZbin channel chuck full of great information.

[@johndavey72]

Thankyou Wray. Was it your intention to make this in one piece and the other in two . My instinct thought the second method first ! If you see what l mean !

[@proshaper]

This side ( the left side rear tail section) is made one piece using cold shrinking techniques. The right side rear tail section will be made from five pieces all stretched on the English wheel.

[@butziporsche8646]

Hey Wray, what would you guesstimate the total hours to complete the entire skin (not including mounting, reinforcement, etc.)?

[@proshaper]

The total number of hours to make this or that is a very common question. There are so many variables.... What method? What quality of information ( the workability and accuracy of the buck)? What tools? What is the skill set of the craftsman? If you are asking from the perspective of a hobbyist working in his own workshop. How long it takes is when you add up all of the hours at the end of the job. Figure 400 to 800 hrs ( lots of additional hours sourcing and building the buck, cost and accuracy of the buck can vary greatly) as an educated guess. Quality levels depend on the skill set. If you are asking from a commercial perspective the question is how many bodies do you want? In most cases it is only one body. For the shop to stay in business they have to charge time and materials for the whole project. Quality and time can vary from shop to shop.

[@butziporsche8646]

@@proshaper I understand all of that Wray. However, what I was actually asking is how long you would guess it would take for you to complete a body on that buck with this specific method? I realize it’s going to vary greatly based on the skills of the worker, the tools, the materials, etc. My son, my assistant engineer and I want to take vacation together and fly out and take your course. Once the COVID BS dies down.

[@proshaper]

@@butziporsche8646 There are too many variables, but if I worked on my 550 wireform buck everyday for 8 hours a day I would guess it would take me a couple of months to get all of the skin shaped, welded, metal finished, and fitting very well. 300 to 600 hrs would be a good educated guess.

[@TheInsaneShecklador]

I wish you would go back to the longer vids without the fast forwarding or jump cuts but I understand why it might be better for your KZbin view count. Thanks again for these tutorials however long or short they may be.

[@SupperSnailspace]

Could you use similar techniques if steel was used?

[@proshaper]

yes, you will have to use heat to help the internal shrinks.

[@T3glider]

Isn’t the concern about the “English” stretch method thinning the panel too much resolved by starting with a heavier gauge sheet than you would choose otherwise?

[@proshaper]

No , you just make smaller panels. The stretch is very minimal.

[@dougvanallen2212]

Wray man I wish I was a young man I would have taken all of your classes

[@proshaper]

My oldest student so far was Walter he was 84, he was also one of the most attentive with a strong desire to learn. I'll be 70 in a few months, I'm just getting warmed up.😁😊😁

@Doug Van Allen don't let age stop you, it's just a number! if you have the desire and the means, go for it.

[@parrotraiser6541]

The relative time budgets of the two sides (1 part vs multi-part) will be instructive. Traditionally, New Years are times that people resolve to get more exercise. Do you find you have to exercise in a gym to get the strength to do what it clearly a physical job, or does the work itself maintain the muscles? (Chicken & egg question. :-)* )

[@scotty362100]

The new "short" format really sucks, as you don't show hardly any of the processes to "work the panel". You cut from telling us what you are going to do then cut back after you are done. Seems the only thing you are now showing is the work on the english wheel.

[@proshaper]

All of the steps you want to see are in earlier videos, that is what makes them longer. I'm figuring that once a viewer sees me use the my gathering tool two or three times they get it. Showing crushing the gathers down two or three times in my shrinking facilitator should convey what needs to happen and how. Using the English wheel is a more complex skill set. Even though the English wheel is a very simple tool, it has a lot of subtle skill sets you need to learn before you can master it.

[@dannyzuko1843]

Hello Wray, can you explain the strategy for knowing where to hit the gathers as you crush them down?
