tried two different ports to see if the amount of the aluminum could be scaled down
with the larger ports it takes more time to cut
while the smaller allows me to just grab with pliers and snap off

I couldnt see the lines inside the grooves but on both the castings they show up in the same place so Ill be going back over with that jb weld to fill in and make smooth

thanks cycleranger
with the help of the cad work I should be able to get it just right on the points cover with no overhang and better lines that dont have to be gone over with too much work

Following, out of interest what aluminium are you using?

wolf550 · « **Reply #57 on:** April 09, 2023, 05:24:46 PM »

using broken parts from honda cb engines I have accumulated around here
tried different types of aluminum from ebay, lowes, beers and soda cans
but i figured I better keep it in the family

wolf550 · « **Reply #58 on:** April 09, 2023, 05:32:35 PM »

seeing if anyone is near Tennessee that I can send a cover for test fitting
figure I better stop here and see if it fits
Ill send the cover and a sharpie and if they can go through the steps:
see if it slides on
see if the bolt holes line up
see if the sides go all the way to the bottom
Ill keep this up for a few days and then post over in wanted thread

wolf550 · « **Reply #59 on:** April 16, 2023, 08:13:30 AM »

got a few measurements out on the wanted section to see if this will fit
the next step is getting that engine over in knoxville
made another to see how the progress is going but the cavities are still there
keep on at it
watching a few more vids for alternatives and going to download a few books for alternatives
saw a cool guy on youtube called olfoundryguy who made these cool motorcycle badges from aluminum for a club
were awesome!
maybe something like that in the future for the sohc forum

progress

wolf550 · « **Reply #61 on:** April 16, 2023, 04:05:05 PM »

decided to work on the last cover made with little bit of cavites between the fins
luckily there is enough meat to grind down in there to clear away most of it

Nice progress!

thanks bert

luckily I just sold some more parts so I will be checking in with the guy about his 71' motors
this wont be until may though but all is looking good
I was getting anxious enough to almost list my lesters and my #4 exhaust pipe as a last resort!
im sure after some more research and actual test fitting this will be complete and moving on

wolf550 · « **Reply #64 on:** April 27, 2023, 01:12:15 PM »

still waiting for the guy to get back to me about motors he has
in the meantime working on some projects for my nephews

wolf550 · « **Reply #65 on:** April 27, 2023, 01:33:01 PM »

success! i guess typing about it gets it going!
got ahold of the gent and going out there tomorrow to get one!

wolf550 · « **Reply #66 on:** April 28, 2023, 02:27:56 PM »

went out today to get the motor
super nice guy
grew up with 750's and sold his sandcast after he stopped riding
had alot of other 750 goodies there, another 750 parts engine
a chopper 750 with harley front
airbox stuff
a couple other motorcycles he had stashed in the back under covers but I think they were kawasaki by the look of the mag wheel not covered by the cloth it had that cross pattern look to it.
these motors dont get lighter do they
luckily he had a dolly and helped me get it in the car

wolf550 · « **Reply #67 on:** April 28, 2023, 03:57:17 PM »

got around to getting this thing out of the back of the hatch and onto my dolly

wolf550 · « **Reply #68 on:** April 28, 2023, 03:58:19 PM »

for those 750 nuts wanting to know the engine number

wolf550 · « **Reply #69 on:** April 28, 2023, 04:01:54 PM »

so my wife decided to wait on getting the driveway paved so out of the car and up the hill that was not level

wolf550 · « **Reply #70 on:** April 28, 2023, 04:04:43 PM »

over the railing that was the same height as the hatch
and through the gravel that the wheels did not want to roll through

wolf550 · « **Reply #71 on:** April 28, 2023, 04:06:07 PM »

and even though the floor was only a couple inches taller than where the engine was it felt like a fence getting onto the tire

wolf550 · « **Reply #72 on:** April 28, 2023, 04:08:17 PM »

luckily I have two tires one for the engine and one for the basketball sized Hemorrhoid that I think I got from this adventure! LOL!

wolf550 · « **Reply #73 on:** April 28, 2023, 04:09:00 PM »

but on a side note
IT FITS!

wolf550 · « **Reply #74 on:** April 28, 2023, 04:10:40 PM »

it looks like the outside is pretty good on matching the bottom starter wall
