Featured Land Speed Racing 2023

you betchum

 

the ignition from australia is in the post. due here this coming week. handmade unit by a retired electronics person who does them for the local sidecar racers.

 

. . . and it has arrived.



did this post?

 

obviously not.

messed up forum. i cant post images from my phone because thats not where they are.

oh well.

anyway, the diagram you cannot see shows the machining specs for a 180-degree ignition hall affect rotor. you also cannot see the photograph of a finished example.

and you cannot see the photograph of the ignition box, illustrating the different harness connections for power, sensors, and rev limit/;advance control.

sorry folks.

the forum imaging application is messed up5. not within my power to fix.

^^^these are the image format options imgur.com gives me for an image that they are hosting on that site. you can click on the displayed url of 1, 4, and 6 to see a page containing an upload screen for that image. while this was not a problem in th epast, none of the available options allow the image to simply appear in the post.

 

^^^this image is from my phone. i can still upload images on this forum from my phone, but most of my images aren't stored there. i strip stuff out of my phone regularly.

this was not a problem a few months ago. i could link to images i stored on imgur.com without difficulty.

i still can, on other forums. the images that i cannot post here appear normally on britbike.com and triumphrat.com. they do not appear on triumphtalk.com.

 

shit fire i can post images tonight.

sort of.

thats the rotor for the ignition. looks like the flat bottom of a soup can with 180 degrees of side left standing up 10mm. the coils are in parallel, not series, so each is 12volts not 6 and there is no waste spark.

the leading and trailing edges of the shutter are 180 degrees apart, not like its shown in this picture for a n offset crank. so one coil is fired at one end of the shutter, and the other is fired at the other.

the guy that makes the ignition just does the transistor box and sends you these drawings for the rotor. i spoke to one of my machinists yesterday and got contact infor for his artist-machinist to do this rotor.

that guy has a CNC shop, and is the one with the rotary table who cut the adjuster slots in my ARD magneto to allow me to knock the FM mag unit back and forth about 10 degrees so i could adjust it with a timing light while the mmotor was running.

another story.

 

shit the system is slow. it takes ten minutes to upload a single image. maybe my satellite internet is the problem here.

im going to try to upload an image of the rotor after one has been machined. it used to take only seconds, but clearly something has changed.

looks like thats it for tonight.

 

still cannot post from imgur. thats where this image is.

maybe i can screenshot it

 

well shoot

theres the rotor

all this took 40 minutes

 

and what the hell, its autumn, and the turkey vultures are migrating douth to whereever they go. hers a bunch hanging around waiting for stragglers

 

rotors!

i have four machinists for this motorcycle.

one does the cylinder heads

o e does my pistons

another built and repairs the crankshaft

and this guy is the artist, who makes intricate weird stuff, like these ignition rotors:





hes very very good

and very very eccentric

but now i have three to test. he was unsure about the taper, because it didnt calculate out the way it should have. but the rotors fit into an old 72 exhaust cam i brought him, so tomorrow ill see whether i can mount the coils and the transistor box and maybe test em out
