Wow, That is too cool. Can you imagine what a 1920's era machinist at Harley would react if he saw all this?

I am glad you enjoy the YouTube. I don't think many people view the videos I post (shame), perhaps they are dealing with slow connections? Or maybe it is just my narration, I am nervous speaking around cameras why??? The first tool is a ruff cut 80 degree diamond that is being shoved through the material at .025" per revolution and .060 depth of cut running 200 S.F.M..This alloy heats up a lot and the numerically high feed rate sends most of the heat out with the chip glowing, something the camera did not pick up. Afterwards the groove tool removing the material behind the flange amazes me. It is .25" wide and the plunge is a powerful resistance to the machine yet it consumes steel faster than a pie eating contest champion.

joe the videos are cool. more people will view them if you title them. your title of 7425.mov is a title that lots of people share. your uplaod program or you tube gives it out. if someone looks up cannon ball build or joe's build or slow joe they will never find it.if the search 7425.mov they will find 10,000 or more videos with your video somewhere in the mix. ps.can you peel an apple in on strand with that lathe

That's just the way I'm going to feel the next time I crank up my old manual lathe.

I have a friend with a metal working "treadle lathe" so don't complain!

Is the following post not enough, just click either of the below blue lines and the video loads and starts playing automatically. I agree a more descriptive title should be in order. Also a YouTube search for slojovideo will open a list of all the videos on this build. Ah yes..... if it would help with finishing this bike sooner I could program and tool up this machine to peal an apple. Holding on to the apple may be just a little tricky. Rob I just reviewed a video and understand what your are talking about. I will work on it.

I spent time today making tooling for the Okuma on the ole Monarch manual lathe. Photos will be posted of the tooling made. I have only three VDI (quick change) I.D. holders for this machine with a total of twenty available tool stations. This machine requires a tool holder in all the A or upper turret holes, other wise chips will enter into the curvic coupling and damage the machine. The tooling companies make steel plugs for the unused holes that lend themselves well to modification for simple drill holders as you will soon see. Bill is the 37 an ohv HD?

Finish off the weekend

Lets hear it for Buchanan's this time, the big B spokes laced up the rear wheel OK. I have not trued the wheel yet, this is just a trial lacing. Next is to disassemble the wheel and send the rim out for chrome stripping and painting. I am using a Harley 21 inch profile rim on the rear. It does not mach the front rim but has the general style (no spoke hole dimples as the front rim has).
The rear rim is a 21X2.15 where the front is a 21X1.6. I will be using a larger 90 90X21 tire on the back and a 80 90X21 front tire. This is not by choice but actually by default. The larger rear wheel may be a benefit as far as ride comfort, whereas the front has suspension to help smooth things out.
Tony the tigger stopped by today and took care of some of the welding tasks. Tony is a welder who can handle all types of welding and do a good job at every one of them.
Next was to get back on the Okuma set up. This time special nuts and bolts are to be made. I say special because of several reasons. NON-standard thread pitch, head sizes and shapes, don't forget machined not rolled process of the original items.
The throttle control sleeve is welded, drilled, taped, then solder together, good as new.

Holy Smokes Joe! I've got some catchin' up to do! Thanks for picking up the slack Chas!

[Slojo]

The search is on.

I have put a short list together of required items.
1) Cylinders
2) 1915 1916 Cam chest
3) Twist Grips (Is Mrs. Fox still selling?)
4) Steering head, fuel Tank, and oil tank transfers, Decals or what ever one likes to call them.
5) Rear chain guard
6) Original pedal cranks and related parts.
Can anyone help out here on these items? Cash or trades available.

Run Run Run (you sure can't hide)

I ran all day , to the bank to get a charge card issue resolved. Then to the steel supply shop for some all important material to feed those hungry Okumas, they sure have a big appetite. Next to the heat treat shop for some pick up and delivery action. I also took advantage of an opportunity to get an informal education from not one but two of the metallurgists. I had those guys tightening their thinking caps. A good time learning and getting a better idea of who I am conducting business with, after all customer relations are important.
Afterwards a trip to the nickel platters to drop off the new Harley 21X2.15" profile rim for chrome removal. I will be painting the rims so chrome under the paint would be like wearing white socks when you were a kid. Finally it was off to Rams (one of the now famous Slimy Crud's) house for some good Ducati conversations, two pre-recorded Mote G. P. races and pizza.
Race one Casey Stoner (Aussie on a Ducati) was with a commanding lead when he put the process in relax mode that put him way out front, on the tarmac and out of the race. Nicky Hayden former Honda world champion (Now Hilly Billy on a Ducati) took 4th in the second race, race one I missed the end.
Oh every where I go is either work related or Ghost related, Rams was for tire selection and purchase. After watching those Ducatis run (and the pizza thanks Grossman) it was only prudent that I get some of those Italian donuts for desert, the Pirelli's get the nod for the Ghost sneakers.
Pirelli has a narrow and wide tire for the 21" rim. The front will be a MHX90X21 (MH= 2.75/3.00 width) I hope it is 2.75. The rear tire is a 90X90X21 (3.25 width) Night Rider model tire I think (sounded cool looked cool I will take four please) I placed an order for two of each.
I forgot to mention the stop at Butchies house for some important computer time. we located another spring shop who may be able to help me out with the seat suspension. I am using the Messenger #3 half pan saddle with a Messenger Supurba leaf spring "style" seat suspension,,, I hope.

Gone fishing

Another long day of swimming all over the city chasing minnows and materials. I had the opportunity of sifting through a private stash of pearls that are just not found anymore without some good scuba gear. These old digs yielded some interesting seat hardware parts that I was able to reel in.
A trip to another local friends house landed the big fish...this one followed me home for some close scrutiny. A mostly original fish including the original scales (paint) 1914 twin two speed Harley. I spent all evening measuring (checking for legal size) hardware like the brake linkage and clutch pedal to clutch lever rod. Nuts and bolts were also measured for hex size length and corner treatments, washer face or 60 degree chamfer. I also notice the floor fin brackets have no added gills or hardware as latter bracket have. Aluminum foot fins and full round stock tackle rack are just a couple of interesting items on this ole mackerel. I have know of this fish for at least 25 years it is the real thing.
Photos and prints made up, the fish will be returned ASAP (catch and release program). All joking aside this was a true privilege to have such a fine machine lent to me for a short period of time, Thank You Dubya (W). The opportunity is now opened for me to reciprocate, some of the parts I have made will be in the return package as I can see a few items are missing.
I forgot to mention the new spring shop did not have internist in making the seat suspension once they looked at it. They did give me some stock so I can tackle (another fishing term if you did not notice) the job.
A photo will be posted of the borrowed 14.

Ain't that a dandy? It's bikes like this one that occupy my daydreams...

Closing in

Today the trusty Lincoln (my home away from home) took me to see the welder and Motion Industries for sprocket selection. Motion will be quoting five different sprockets with optional heat-treated teeth. These sprockets are for the "transmission" at the pedal crank centerline. I will be able to developed the ratio that works best for the application.
After the sprockets come in they will be taken to the wire E.D.M. (electrical discharge machine) shop to cut out the center spline. This machine cuts through steel with a wire usually about .007 inches in diameter. A high frequency current passes through the wire as the wire passes through the steel. The steel actually is corroded away. "Wire machines" are capable of holding close tolerances to .0001" easily. With my new bearing setup on this assembly dimensional accuracy and roundness is crucial, forcing a sprocket on the assembly is out of the question, an extremely close fit is necessary or the sprockets will work loose.
I found some rod end clevises in my parts that I made and nickel plated years ago they will work on the clutch rod and one end of the brake rod.
The Monarch lathe was busy tonight. A new brake pedal guide bushing was made, this item bolts to the floor board bracket and has a circular groove cut in it to allow the "blade" type brake pedal to pass through and not bend away from its proper location.
Most of my time tonight was spent making the ring nut that holds the sprocket onto the transmission. Three were produced as that is how many I could get out of the stock. It is good to have a couple spares of these items on hand. Following photos will show how close I came to only getting two ring nuts from the available material.

You've really got things rollin' now Joe!

A long two day update

The past two days have been busy preparing for plating and painting. With W's loaner 1914 I have found some detailed discrepancies that had to be addressed. For example my brake pedal and clutch pedal required adjusting to be correct for this bike. I also made and riveted on the pedals new clutch and brake rod pull pins.
New special ordered "heat treated" sprockets are now on order from Bearing Services expect one or two weeks before they appear. Other progress includes the arrival of new slim line Kaydon Bearings for the "transmission", the chrome on the rear wheel rim is striped, ready for pick up and more ring nuts, a smaller set had to be made for the "transmission".
The handlebars required all day attention, it appears that 1914 is a one year only handlebar by way of the early style bar with late style cable exit bosses. My handle bars are a hybrid, the bends are 1909 style originally intended for use on my 09 until I found original bars for the ohniner. These handlebars are with the early vertical posts and bends combined with the spacing of the post to fit the slightly wider fork being used form a 1916-1923 J model.
For those You Tubers (http://www.youtube.com/watch?v=3AHc_YCTaEI) I shot a brief machining center operation of a concave contour, ball milled into the cable retaining devise that I later silver soldered onto the handlebar's mating curve. These two cable mounting bosses were time consuming to fabricate. Our resident handlebar dude Tom Faber apparently makes these items only when necessary. I called him to see if he had any in stock and he laughed, said make a couple up, you can knock them out in five minutes. I told Tom I would rather drive 2.5 hours to his house and allow him make them in five minutes for me. I know he must not enjoy making these items they are difficult to get cosmetically right and fit the curve of the handle bars. About eight hours later the parts were fabricated, silver soldered on to the bars, drilled and metal finished to look like original.
