1940 Serviglide

[Ricks]

Interesting covering. I think that is what you see on many HDMI cables these days.

A few more parts made.  Three ferrules for the cable ends.  Three cups for the springs on the front end.  I ended up welding the detent holes all of the way closed and re-drilled them.  Made for a cleaner job

Tom, this is fantastic work!  Are you shooting for Portland 2021 or 2022 for the debut?

[kartjockey]

Planning on 2021 in Portland.  Good, bad, or indifferent! 

Personal goal to let Rodney and Bob(original owners son)  see it and ride it this summer.

Made this tapered punch to straighten the frame tubes. I heated the ends and then drove the punch into it to force it out round again.  The corks should go in nicely now.  Bob said he can account for a few dents here and there when he was riding it  and even dumped it in to a ditch once!

The frame is ready but will have it blasted once more to go over my repairs and the bottom needs blasted better.  While cleaning up the frame I uncovered four 8-32 tapped holes in the floor board and four more in the neck. Two on each side.  Wondering if that is the way the splash guard attaches at the top.  Not sure about the floor board holes but I swear I can see screw heads in the 1939 brochure pictures.

Tom, is picture 3 the back of the headstock? That looks like it was touch cut!

[kartjockey]

Yes.  Seems they got the torch out a few times!  Wayne's 39  looks much the same.

I couldn’t stop myself, I’d have to get the air sander  and smooth that out!

Tom ,

Not sure this will apply , but , I was browsing and came across some wiring that you might be interested in for this build .

Thanks PD.  Cloth covered wired is definitely in the plans.

The worn piece has been remade and welded back on .  I don't have the air breather for this bike or even know what one looks like. I assume this may be the original ait tube as it looks like it was mated to the carb for a long time but unsure.  Sure looks like it will take something like this to clear the rear wheel.

I was surprised once again when I uncovered more brazing!  Pic shows comparison to later H model cylinder.  Although  the original Serviglide crank pulley would certainly still have worked I decided to use another that was better.  Original was 2.960" OD so I figured I would just turn the OD down on the replacement(3.187) for clearance.  That thing was as hard as a rock!!.  I plunged into it with carbide and once I got a curler started it would cut.  Thinking about how much the belt would rub on it when still I guess I understand it.  The original does not seem hardened as I could mark it with a file.  Maybe because the belt is always engaged on a direct drive.

I’m surprised that you have a one piece pulley, my 1939 has the multi piece pulley that allows for gearing changes.

Hmm ,

Does the Serviglide have a longer stroke or is it just the sleeve skirt that makes it taller ?

Shorter stroke  2 1/4"
