1948 Raleigh Sports Tourist - Model 23

Good weather to start this week, but that is supposed to last only a couple of days. The lawn mowers are back out and about. I love the smell of freshly cut grass... 

 

Here is one of the bikes I re-built over the winter - a 1948 Raleigh Sports Tourist. This bike combines the Sports frame, 26 inch wheels, and cable brakes with the "Tourist" elements of a chain case, front dynohub, and light set.  The bike appears as "Model 23" in the catalogue.

 

The Model 23 Sports Tourist is very much a "commuter" type bike. It is better-equipped than the basic Model 35 budget Sports, or even the moderately-equipped Sports Light Roadster (Model 22). 

 

This bike is on the heavy side to be a "road" or a "sporty" type bike. It offered the commuter a weather-resistant bicycle that could be ridden to work or class in regular clothing. This bike is aimed at the short or medium length trip to work, class, shop, or the post office.  

 

The bike was available with the old-style, long-arm "trigger"/"flick" shifter, or  the top tube "quadrant" style shifter. For now, I have a good, old quadrant on the bike. I may try converting it to a refurbished long-arm trigger shifter in the future, but for now the quadrant is there and gives good shifting.

 

One of the challenges of these bikes are the old, cloth-covered cable housings. These housings love to dry out and crack. If you're lucky, the are simple, small cracks where the cables take a turn. If you're unlucky, the housing will begin to fray, leaving a mess. If the covers are particularly bad, I replace the whole cable assembly with something newer. But if they can be saved, I use black-colored heat shrink (available online) to bandage the larger cracks. The sections on the bike where you see larger cable covers are the heat shrink "bandages" on the covers. They blend in reasonably well, though they do make the cover look a bit bigger in those areas.

Raleigh pattern cables are fixed-length and not meant to be disassembled. I lubricate them by hanging them up and dropping some Tri-Flow lubricant down the cable cores. Tri-Flow is a thin oil with a teflon component. It helps lubricate old brake cables that need to stay intact.  

This bike has the old-style Sports lamp bracket on the handle bar stem and the old-style, glass lens headlight. The tail light is a bit later type, the original being totally missing when I got the bike. 

 The lighting is still the old-style, incandescent type. I prefer LED lights because they give you the most lighting you can squeeze out of the low-output GH6 hub. But given the age of this bike and the very old-style, glass lens headlight, I stuck with original lighting. This bike will not be ridden at night. 

The headbadge is the original, old-style Raleigh type. It has some wear on it. I suspect the bike may have had a front basket for awhile, which may have rubbed a bit on the lower part of the badge.  

When I cleaned the mechanical areas and bearing surfaces, I found this bike probably did not have many miles on it... or else it was very well-maintained. The bearing surfaces were smooth, with very little wear. 

There are still a few things to consider on this bike. The 1947-48 catalogue shows this bike's standard shifter as the old-style, long-arm shifter, with a cloth-covered shifter cable. I may do that eventually. The top tube quadrant was an option for a more traditional set up. The quadrant is lower-maintenance and easier to fit. (See my article on refurbishing the finicky, early flick shifters). Going to the flick shifter will also mean finding a length of good, cloth-covered shifter cable (not easy). I probably have some of that in a bin somewhere around here... We will see if I make the return to catalogue "standard"...

 

I also need to play a bit with the saddle height. I have the bike set up as an upright commuter, with the bars a bit higher than the saddle. I think that works well for this bike, but I may need to raise the saddle just a bit. I can see why these bikes were such popular machines for the short or medium length trip to the office or college campus. It would make a very comfortable commuter. I find my more spartan Raleigh 35 better for longer trips over the road or in hilly country. 

Without further delays, here are the specs:

• 23-inch men's frame
• 26 x 1 3/8 wheels with Westrick Raleigh Pattern rims and stainless "R"-stamp Raleigh spokes
• Michelin World Tour tires, Schwalbe tubes 
• 1948 Sturmey Archer AW rear hub
• 1947 Sturmey Archer GH6 front hub ("black side", pre-1951 type)
• Original, cloth-covered cable housings
• Original chain case with all the various sliders, clips, etc. 
• Incandescent bulb lighting - I did not convert this bike to LED. 
• Brooks B66 saddle
• Raleigh industries pedals with "spurs"
• 48-tooth chainring, 22-tooth rear cog 
• Acorn saddle bag 
• Lucas bell 

 

Repairing Early Sturmey Archer Trigger Shifters

 

The 1940 Schwinn New World project continues, but I took a little time off that project to work on some early Sturmey Archer Trigger shifters. These are the "long arm" handlebar shifters used from the late 1930s to the late 1940s. They have some peculiar features and can be somewhat tricky to repair.

First, remove the external r-spring (if it's not already missing). Then the two binder pins are knocked out, from back to front, using a slender punch. The center pin that holds the lever and ratchet assembly goes first, then the rather/lever assembly slides out. Be careful - there are two small, grub pins holding this assembly together. Do not lose them. Second, the corner pin is knocked out, which will take the pawl with it.

Second, clean and straighten the inside of the shifter frame. Be careful - the metal is somewhat soft and thin. After cleaning, check to see if the shifter frame is loose on the handlebar clamp.

 

Tops of two rivets holding the shifter frame to the clamp

There are a couple versions of the rivets attaching to two. Early shifters have two, domed rivets that often work loose. Later versions have stronger rivets and don't loosen as easily. If your shifter frame is loose, you can tighten them using two punches or an arbor press. Place an appropriately sized punch in a vise and mount the shifter body so that the punch is against the rivet head. Next, use a second punch to strike the opposite side of the rivet. The rivet should be "sandwiched" between the two punches, tightening the fit. Be careful doing this, not to hit your hand or allow the punches to move.

Third, clean the ratchet and lever assembly. Make sure the grub pins are properly in place. Also, clean the pawl and make sure the pawl's arms are straight. Gently straighten the pawl if it is bent. Also, gently clean the faceplate. Gently straighten the face plate as needed. Be careful, the faceplate is fragile. I use a little WD40 on a soft cloth to clean the face plate. 

Disassembled Shifter

Now that everything is clean and straightened, you can re-assemble. Lubricate all the moving parts with medium oil or light/thin grease. Put the face plate back in place and insert the pawl into the shifter frame. Take the corner binder pin and slide it into position until it's aligned with the hole in the back of the frame. Tap it through with a hammer so that it protrudes from the back. Set the pin back on an anvil/vise face and flatten it by striking the pin head. The vise/anvil will spread the pin back so it stays in place and binds the pawl and face plate into place.

Re-insert the ratchet and lever into the shifter frame. Take the remaining binder pin and slide it through the holes until it reaches the hole in the back of the frame. Tap the pin through. Set the pin back on the vise/anvil and strike the head with the hammer (as you did for the other pin). 

 Take your r-spring, insert it and pop it into position on the pawl. 

If you need to make a new r-spring, you can make one from a 1/4-inch hitch pin clip. These are available at some of the big-box and hardware stores (in the USA at least). Gently open the clip a bit with a screwdriver. The legs will need to be shortened and flatted. A dremel tool works well for this cutting and flattening task. If you have a good spring, you can copy the dimensions of that. Or you re-assemble your shifter first and then hand-fit the shortened clip until it works correctly. 

 

 Above is a package for a 1/4" hitch pin clip. The package shows the original shape and the modified clip is on top of the package for comparison. Note the shape of the clip has been changed and the legs shortened. Don't bend too far - it will lose its springiness if you go too far.

Another option is to use a 1960s-70s era wire spring, as shown in the photo below. If you wanted to do this, you would attach the spring back in the step when you re-installed the corner binder pin and pawl. The photo shows how it would work. Make sure your wire spring is long enough to reach (some springs may not be long enough).

The final product is a nice, clean, functioning early trigger shifter. A few words of caution are needed. First, it is possible to lose the R-spring because it falls out of the shifter. This often happens when the lever is pulled too far, causing the pawl to twist out of position and the spring to lose tension. Without any tension on the spring, it is free to fall out and get lost. This is how so many of these shifters turn up without springs today. Second, abuse of the shifter will cause the rivets to loosen and the whole shifter to become wobbly on the clamp. Go easy on these old parts.

 

 

But the final product is a nice, old piece of technology from before Sturmey Archer had perfected the trigger concept. The 1949 and later triggers are much better parts, but these older shifters serve a place on three speeds dating to the late 1930s through the late 1940s. They served on many bikes during the same era as the quadrant top tube shifters.

 

 

 

 

 

Kickstarting Spring... For Now

 We had unseasonably warm weather here this week. Temperatures were in the 80's (26 to 33c) most of the week. We also had some summer-like thunderstorms at night. Next week is supposed to be much cooler. 

The warm weather gave an opportunity to dust off and ride a couple classic bikes: my black 1964 Schwinn Traveler and my green 1959 Schwinn Traveler. I love 1950s and 60s era Schwinn Traveler bikes, so much so that I more closely examined them in a guide on this website.
