  1. Hi all, well criminy! I was not gonna show this frame till I'd done a bunch of stuff, but....... Myron, you know
    who you are!!! I've been holding out on taking pics, and showing this for about 3 months as I was looking
    forward to putting the OHV Whizzer in it. Making it into a full motorcycle, and showing it then.

    My wife, Diane is standing by this most recent addition to the stable. She is only 5'6" so you-all can
    see the scale of the bike. I was able to stand over the top bar, and "squat" on it, to compress the
    springs, to install the new longer rebound springs. The earlier rebound springs were
    not stiff enuff, resulting in the fork "lifting" when front brake was applied hard.
    I dunno what I'm gonna do next, perhaps build the 09, or 10 model, but I will need to have a real
    solid idea of it's potential before I will contract 10 bikes to be fabbed.

  3. The Simpson model numbering scheme

    Hi Spunout, and thanks for the kind words! I started numbering major things that have happened to me in the building of motorbikes. #1 was very commonplace, run of the mill, we've all seen them before 80's Taiwan "Schwinn Approved" black cruiser 7 years ago. It was a barn bike given to me by a friend. A SpitFire 48, good running bike, I later added all the frills to it, this is shortly after I got it running.
    I built a bunch of bikes, and then came Old No.6 a ladies mtn bike I got free. I wanted an antique look, kinda obvious, eh?
    so then a bunch of stuff happened and then, I got a wild hair, and along came the Model 07, a ladies Sekae Japanese cruiser I got free. I did an article on my site about building it. "Could your sister's old bike be your new motorbike"?
    then you've seen my 08, and now the 09. I would guess that I have built about 30-35 of the standard "screw an engine on a bicycle" type builds and I rarely, if ever do that anymore. The most recent is that lil 4-stroke Western Flyer, and I had a reason to do that, as I'm testing the engine kit's potential. I'm ready to do a very complete AM (as I call them)

    Very impressive build's Mike

    Warms my heart to see old iron on fresh rubber - especially when it's grips are sweaty and the tank is still half full.

    Looks like the '09 will be a hit Mike! I never can get enough of that classic style.

    What will you charge for frame and forks, raw?

  7. Looks awesome!

    Sweet No. 09, Mike!!! Looks like the Harleys from the 1910s. I have a bicycle replica of a 1914 Harley boardtracker. Hopefully soon I can put a motor on it! Great job!! :grin:
  11. 09 revisited

    Hi all, thanks for the kind comments, I really appreciate it.

    My Model 10 is in another state in a secret laboratory (pronounced la BOOR a tory) being emotionally disected by a factory famous for its work, including frames for Big Dog Choppers, and Saxon.

    After being photographed in the nude (she's never seen paint), the pics were loaded into the puter, digitalized in Cad, and off to water jet for cutting. I'm very excited to see this work!

    I'm engaging a friend who is a graphics wizard, to desigh and do my stripes and logo this time. Maybe I need to divert from "Homemade" about now?

    This leaves me without that old prototype for the second time, 2 weeks to chop her, and now she's been gone 2 more I think. So, "Whats a feller to do?"

    The 09 has been resting, and I could not live with the increased rear wheelbase so I spent about 3 hours sunday afternoon designing new dropouts to fit the bike, reducing the wheelbase so that the 84760 belt will again fit.

    I went to steel house and had 2 pieces of 3/16th's sheared to shape, and now must tack them together, so when I carve them on my table-saw, they will be identical. (oddly I did say table saw).

    Currently, Power is the BTR OHV whizzer, and we'll be seeing in the near future how she runs, tho I'm bummed about having to make, jig, and weld the dropouts myself. I've made an intake manifold, ex manifold, and headpipe already, I have the brass to make the breather, and steel for the old-timey Indian style 2" muffler, tho I still must build an air cleaner.

    Currently, I have no plans to change anything other than the rear end, and then will need to attack the toolbox, which I think will not be the full flat type, but rather a cylinder, or triangle shape.

    I do not see any advantage to migrate the 09 into the Model 10's configuration, and am still toying with color. My gut feeling is that 09 should be Indian Red, and the Model 10 to be Renault Grey, with either red or maroon stripes and lettering. I will be full fendering both bikes, they will not be the "Racer" format.

    I do have plain engine covers, so when the time is right I can have someone carve Simpson Motor Company into the engine cover. It sometimes amazes me how difficult it is to do things the "old timey" way.

  12. Very nice! Great attention to details.
  13. Model 09 revisited

    Hi Zomby and thanks, there are many things I would like to ask you about your bike!

    I've been working on the 09 since I do not have the model 10 prototype to refine, as it is in others hands now. I carved new dropouts, and jigged and installed them. There is much work to be done there till it looks the way I want, partially do to some of my misconceptions in the tube slots of the dropouts.

    Made the drop stand, and it's stops, and did a quick assembly to check everything, and I think it's gonna work! ??? The 84760 belt is in place, and I got to make the tension spring adapter (Center Pulley), and a bunch of other stuff.

  14. Model 09, nearing "Firing Time"

    Hi all, production continues in AZ on model 10, much news, none confirmed.

    Model 09 is progressing nicely, more to do tomorrow, I got news that OHV #1 got 155 miles on it this weekend down in Central Coast.

    I'm excited about running mine (#002) he's reporting 45 clocked with no problems, and blasting up over hills. That will be fun!

    Here are a few pics of yet incomplete Model 09 Prototype. I'm excited to be able to climb aboard, and hear the new Brass Muffler, roaring out it's approval.
