Degree wheels and piston stops

Gidday all.
Found here a mention of degree wheel mounting adaptors and piston stops. cant find it again though.
A consequence of being doddery I suppose.
Anyway I have an idea myself for this sort of thing.
However, I am dead against just directly copying someone else's idea. thats piracy. parts modified is a different matter.
So as not to steal any one's thunder, would it be possible to see some photos of this.
My idea was to tap out the crank nut to a full thread and screw in a mounting adaptor.
is this what has been suggested.
i am genuinly not trying to pinch any one's idea here.
piston stops are a differnt matter. there are probably a few ways to do this.
but when i do mine, and post photos share as an example, the last thing I want is allegations of piracy.
Any advice appreciated bradley

Unless you offer it for sale, and its only for self use, piracy doesn't come into it anywhere ?
[Note that this is NOT the same as downloading pirated movies !!]

If it hasn't been trademarked or copyrighted, and is in the public domain or has been shown in the public domain,
the copyright folks won't even look at it...

Thank you for that. it is very informative.
I am only trying to head off any trouble if I show some pics maybe here on the forum..
Its pounds to peanuts that some one will grumble.
Thanks again bradley

B. Rad is this the thread you were looking for...http://www.accessnorton.com/best-tools-picture-thread-t19661-30.html . If so, that degree adapter was one I made. I'm not sure where the design came from - I think I made it up based on a similar one for another bike. Or I may have copied it - I don't see anything proprietary here. You're welcome to it - I can send you a CAD file if you want it as a starting point...

Gidday David
Thanks very much. I just had a quick look at the link u gave. good one. but I am a real dumb ass when it comes to this computer hickey stuff. I dont even have a cell phone Mate.

So I am just replying and will go back and have a real detailed look. looks like a very interesting site.

it would be very kind if you sent me a CAD file please. My mate has the stuff and knowledge to do CAD.
That file would be a good starting point.
Do you need my email address?.
thanks again David bradley
david, why this interests me is I still run points.

David,

I could really use one of these items for my race bike tool box David.....the timing marks were on a belt pulley that destroyed itself so I need to degree it again to make marks on a new one....and somehow I don't thinkk this is the last time I will do this!

Steve (UK based)

Just a warning to anyone thinking of going on line or EBay to buy a typical "top dead center/piston stop" tool, I have one I bought years ago to use on my BSA and even though the seller said they work on All Brit bikes it will NOT clear the intake valve on a Norton... Just as Dave (napanorton here) did with his the shaft has to be turned down some to clear the valve. I was going to turn mine down & install a grub screw to lock it in place making it a piston "stop" tool but a friend loaned me one that will clear, has a knob to lock the shaft & a built in micrometer to dial it up or down in 1000th of a inch increments to allow finding TDC that way too. I needed a tool to mount a degree wheel as I too am in the process of doing the degree wheel check of my timing marks while installing a new Tri-Spark so I contacted Dave (napanorton) who has so graciously offered to send me one, and to his credit like he did with deets55 in the original post he refused payment but ask that I make a donation to this forum which I will gladly do. Kudos to you Dave... Glenn T.S.

SteveA - As an exercise (I've never had to ship anything TO the UK), I sent one to the UK a few days ago and unfortunately the overseas shipping costs were a bit rich for my blood. It was over $24 via USPS for the dumb thing. I doubt it's really worth it. PM me if you want to try to persuade me...

So thanks to the degree wheel tool Dave (napanorton) sent me I was able to check the marks on my primary covers timing plate & rotor & found mine were only off by (2) degrees advanced. I checked it three times & it allways came out the same. Not far off but I'm glad to know about it.. Thanks again for the tool Dave and I found your website very helpful, Glenn T.S.
