One more tip, When I made the drill pattern on my PC, I printed out the template on transparent plastic overhead projector film using a laser printer. This made the lining up of the template on the rotor very easy.
I used 5/16 and drilled on my vertical mill. No pilot drill, just plenty of plain motor oil which I use for any machining. Plain HSS drill, which I sharpened a couple of times near the end.
The SS allen screws etc. are much cheaper at your local bolt/screw supplier if you live in/near a fair sized town. I was buying from The Bolt Depot and found that both of my local places are much cheaper. Buying ss bolts and making them shiny is addictive! ;D
Never heard of that software, but Looked it up online and discovered (of course) that it is PC only, and I'm a Mac man. Guess I'll take some measurements and try to build it in Photoshop, but I'm not that skilled a designer.
Did you design the rear disc template on this software as well? If so couldn't you just convert it to a PDF file as I read online the software is capable of that?
Another approach - if you keep the number of swirls or whatever to 6 (or multiples thereof), you can make a board with a pivot for the disc center to rotate on and put a hole to pin the disc thru the mounting hole. They are 60 degrees apart. Add several pinning holes 10 or 20 degree offset from the first one and you can clamp it all on the drill press, mark your first hole, and then rotate it around and mark all the other similar holes for as many copies as you need. Hope that made sense.
I'm just about done with mine, doing a sparse pattern of 3-2-3-2-3-2 indexed off the mounting holes. Marking all the holes with a center drill was really quick. My press doesn't have a slow enough speed so I'm burning up bits tho.
Ok, finished that up this afternoon... I only have 15 holes so it didn't take long. Things I learned:
1. I tried both the titanium coated bits and the cobalt bits from Sears; the cobalt was definitely much superior for a very small additional cost.
2. 1/8" and 1/4" worked easy; the 3/8" final size was grabbing on me until I started holding the disc down more firmly. I'd drill until the oil smoked, let the bit cool while putting a little more oil on, and drill some more. (My drill press isn't slow enough, so especially the 3/8" was turning too fast.)
3. After 40+ years of messing with drills I finally learned how to sharpen a bit. It's dead easy! My first holes with the newly sharpened cobalt were better than when it was new.

I was wondering what bad things would happen if you only drilled 3 or 4 holes, on the edge, spaced around the disc. I don't particularly want the whole pattern, but I'd like to have something to attach a disc lock to...

I used this link to drill holes in my disk and had no troubles at all. Bought three colbalt Sears 5/16 bits and only used one on both disks, never got dull, but the drill was on SLOW, SLOW speed and I used LOTS of oil, found an old can of Royal Triten oil, that is really thick, like 50w, it worked great, must be a little grafite in it.
I would do it again in a heart beat. I did tap pilot holes first to see the pattern. Used the template and sharpe to mark the pattern, that took longer than the drilling, about half hour per disk and I used three holes. It doesn't quite get the whole pad covered, but should do the trick for wet braking and looks Cool!

joshua: The regulator/rectifier unit I got from Mikes PMA has closer hole spacing than original. Are we supposed to mill the holes to fit?
Jun 7, 2017 19:25:58 GMT -5
joshua: My bad. I found the bracket they supplied to mount the rectifier/regulator... Uh oh. How is this meant to work? Which way is it meant to mount? Looks like I have to use some spacers or something. Good instructions would be nice.

craig8johnson: I'm checking the charging system. I'm afraid I might have fried the last battery. With the solid state regulator (after market) what should it be charging at. The book says, I think, 15 volts. I'm hitting 17 when revved. Is that too high?
Jul 11, 2017 18:06:19 GMT -5
gggGary: Yes 17 volts is too high, about 14 volts is max, sounds like you don't have the right regulator or it's wired wrong.

tt650: Trying to breathe life into a 1980 that's been stored (indoors) for 25 yrs. Air filters are dry rotted. Have cleaned carbs but she only runs briefly on choke then stops. Need jet setting info and other ideas that might help her idle and rev.

trix13: Hey everyone! New to the forum and am fighting those gremlins!! New charging system, ignition switch, coil and fuse box. Resistance is higher than normal on the ignition pick up so I'm trying to find one. No such luck yet.

trix13: Also, even though all of my connections are clean, I cannot seem to find out why , when at higher rpms, I hit the signals and the rpms pulse with the signals...hahah. same with the brake light. I appreciate all input!!

jimothyj: Hello everyone, I just joined & wish would have known about this site in 2014 when I brought my 1974 TX650A back from the grave. I have spent a good deal of $$ and alot of time on it. Just painted it and working on electrical, I will post pics soon,

louisvan: trix13 - I had a problem with my 1975 SX650. When I got to highway speeds, the engine lost power. The problem was in the connectors. At a certain vibration and the wind pushing on the wiring loom, the connector lost continuity. A bad crimp to the wire.
