Default Weekend seat project

IMG_0682.jpg

Hi All, this weekend I set out to make a seat for an historic racing sports car I am restoring.I have had it over 20 years so I retired all my "B" and "C" grade clients and decided to do some of my own stuff, amazing how much time that frees up!!
I have got it done to a useable stage, but it is certainly not Concours d'Elegance or even up to the standard of most guys on here so I have some questions.
I think I was using too high a pressure on the wheel as the tracks are very visible.
This may be my own impatience for results ,or just lack of knowledge or skill.
I have had the wheel (From Peter Tommassini) for about a month and this is my first project.
The main wheel does not have the chrome like finish that I see on a lot of wheels and has an "off the machine" finish which does not polish the work.
Should I polish the wheel , chrome it , or will it "work in"?
Should I make wooden or plastic piercing chassis punches as the steel ones I have mark the work , or was I just a little bit too gung ho?
I didnt have any wire on hand so I rolled the edge around brake line tubing.
Is this OK or I should I use solid in future?
Lastly, can someone on here who actually knows what they are doing ,unlike me who is 'learning as I go and teaching myself" be able to tell me how long a job like this should take??
It seemed to go on for ever!!
I kept a job card on it as if it was an engineering job, so ,including the designing it took me 19 hours and I would have thought about half that for a competent tradesman would have been about right.
Any thoughts??
I had the material in stock so no time was wasted shopping ,but I may have used incorrect methods or sequences that could have slowed things up somewhat??
An apprentice, or second pair of hands might have helped as well because cursing doesnt seem to help much in that area!!
If anybody is interested I can put up some pictures as to what order I tried to do things
Thanks to all for all your input .
cheers Greg

Mark out and blocking.

Hopefully that has worked!!
Next I wheeled a bit, and tipped up an edge.
I had to shrink a bit so I did a sort of "pie crust' pucker and locked these and shrunk by hammer and dollyIMG_0654.jpg

Nice work, I like the rivets.

Next was refining the flange to angle back at the 20 degrees to suit the driving position in the car and to try and make the whole thing a bit neater.
(the standards are sure high on here!!)
Then mark out the back and put it through the slip rollersIMG_0658.jpg

Next came piercing the back with the roll over chassis punch to add some aeration and stiffness, somewhere in here I clecoed the back to the base and at some time I hard rivetted itIMG_0663.jpg

This was about the start of the second day and I ran the back through the jenny to add some stiffness and to give me some idea of where and how I might try to do a wired edge, but no wire available on a Sunday so maybe some brake tubing from the shop!!

Next I used the Tommassini solder trick to mark the pattern where the piercings were so I could start on the boomerang stiffnerIMG_0674.jpg

And finally some assembly!!
It finished up light, strong, stiff, and it fitted the chassis and the driver well.
Some doublers were rivetted in for the pick up points and some seatbelt penetrations were made and wired after these pictures, but all in all I was happy with the result because it was a component that could not be bought to do the job and it fitted the era and technology of the car,
Thanks all for all the information I have gleaned from posts on here
cheers Greg
