Bertin C 37 Restoration Part 8

The frame work on the Bertin was done by Jody Lee of Jester Bicycles based here in the Niagara Region of Ontario, Canada. (Contact information is available in the special box in the right sidebar of the site.) In Part 5, you saw the raw metal work prior to final finishing and priming as shown in the previous link. Once the paint was stripped and final finishing and priming took place, Jody painted the frame and fork in his spray booth. The paint was a two stage, base coat / clear coat and the two photos below reveal the frame and fork freshly painted, decaled  and hanging up curing.

The decal work on the frameset was from Velocals. The period French Reynolds 531 seat tube decal as well as the specific Bertin  decals were all perfectly rendered as was the clear chainstay protector. The total cost for the decals was $63.85 USD. Previously, Jody had colour coated the frame, clear coated it, applied decals and then catalyzed clear coated followed by fine compound. I waxed the frame after it had cured with standard, Simoniz automotive paste wax. The cost of the frame and fork single colour paint job was $250 CDN which compares very favourably to the $625 CDN for a single colour frame and fork paint job at a Toronto firm.

Below are some roughly comparable before and after photographs of the frameset. To see detail, click on the photo to enlarge it and click on the enlargement to enlarge again and maximize details.

In Part 7, I had advised restorers to check the fit and functionality of all parts as soon as they are obtained to avoid slow downs later.  Although Jody had checked alignment, facing, chased threads and handed the frameset back with the headset installed, I had not properly checked seat post fit. A Simplex post I thought had been machined to the correct diameter did not fit and the seat tube was slightly undersize as well. I ended up ordering a NOS (new old stock) Simplex seat post from Bicycle Classics and having Jody Lee ream the seat tube out and hone it to 26.6 mm from the stock 26.4 mm of the French dimensioned Reynolds 531.

As it is now, the last of the cutting oil from the reaming has pooled in the bottom bracket shell and been removed so it is possible to install the cups and axle of the Stronglight 93 bottom bracket. The next phase of the project is final assembly and then a project evaluation. Part 9 will be the installment on assembly and shake down and that is next.

  1. Looking just beautiful! Exactly my kind of bike. In fact it looks a lot like my C37. Did you add the braze ons? My frame had none but I had them added when I got it painted. i wasn’t thinking when the derailleur cable guides were added because they are under the b.b. shell. They should have been on top of the shell to be more period correct. Oh, well. Looking forward to viewing the final project.

  2. Hi, Don-

    Great to hear from you again and especially as you are saying nice things about the project! The build up is going on as we write and will be posted on soon – circumstances permitting. I think the cable guides on your bike are most appropriate with the late 70s / early 80s decals on the frame. As well, those top of the bracket cable guides are getting hard to find – my frame builder luckily had some in a bin as his suppliers were out. To let people see what you mean about your C 37’s changes, I have linked here to the December 2012 overview which shows them. I just hope mine will look as good as yours in the third photo!
