Dong Fang DF 250 RTB Bobber Information

Fab them all and do some decent hardening. It won't be a problem for you.

That way, you will kill two bird with one stone - you'll get your studs AND (which is even more important), you'll convince your lady one more time, that those chunks of cast iron named "South Bend" and "Brigdeport" are NOT clogging garage - they are essential for nowadays household.

And don't hesitate to squeeze "Virago's" twin in your DF - it'll be a... "mechanical delicacy".

yes, machining is only a infrequent hobby, but perhaps this bike alone has justified my lathe, and to less extent mill, more than any other single item i own.
to keep this thing running ive made sprocket studs, gear shift linkage, gear shift stud, brake/clutch lever bushings, decked cylinder head, trued cylinder/head faces, various other fittings to mount replacement head/fog lights.

And now a cylinder stud i guess.. but if you read up on these you will find the consensus that home made isnt feasible.
Proper material, treatment and thread formation is out of my capabilities...

- threads should be rolled, i dont have the equipment
- Home brew hardening is vastly inferior to production, (i went through too many home made sprocket studs due to inadequate hardening)

So basically i don't have the experience to know home made will or will not hold up.
Though here seems i don't have a choice, this stud is not sold.

I suppose a good bet and saved time would be a production bolt of same threading, use that on the head side and then cut and thread the bottom side where conditions are less harsh.

Then again i when i get the stud out, I wont at all be surprised to find an unhardened stud with common cut threads...
