My first build - Schwinn Del Mar

[Irish John]

I like the cruiser frames but the distance from the engine to the frame is long and I have to make up the distance. I am building this now, I will let you know how it turns out. I am hoping that it will also help in the vibration also (IE isolate some) if this works out I will use it on my Schwinn. Have fun, Dave

I use an extra engine block spacer to reach the gooseneck downtube on a cruiser and then fix it to the tube with a single 8mm bolt through the downtube. Looks clean and holds it really fast.

This is what I ended up with. The other one concentrated too much vibration at the mounting points to the frame, it then just seared the aircraft rivet. The vibration is the same. Have fun, Dave

The other one was a nice looking piece of metalwork but I could see that it wasn't going to withstand the vibrations from the motor. Not only are rivets no good but the M6 studs that come with the motor have a tendency to snap from fatigue pretty quickly. M8 studs are much better but there isn't enough room to fit them without going too near the edge of the engine casing. Never use the studs that come with the kit cos they are poor quality metal - make your own from 12.9 hardness high tensile steel.

Well on the whole Upgrading the studs thing. I have done 19 bikes and 2 of them had the harder steel. The thing you watch out for is the standard 5.5mm rolled thread soft steel. Upgrade as you will but I just got my order from Nantong Jiali and they are by far the best hardest true++ 6mm studs I've seen I used them on build 18 and put 13lbs torq. Oh Wow I remember stripping so many of the others at 11lbs. 13 was just what the Doctor ordered! No movement even with the vibration proof pads. LiveFast has some hardened good ones.

You get the Just though

I use SS its tough not hard!

 

[Hot Dog Piggy Tails]

Thats what I use on the front rear is B7 which is more maleable than grade 8 and is as strong as Stainless.

 

[Hot Dog Piggy Tails]

The Stainless Steel works great in 1/4" though. I use it when were out of B7. The only time hard ones are the best is 6mm only because the clamp on the other side of the tube being mounted toois for 6mm and with a 1/4" the surface is'nt great enough thus the mounting bolt/stud gets a Pinch point in it. Making Maleable And Tensil a must. This is why I don't use regular grade 5 or 7, or 8 very often. I do use Stainless too. the flat front is generally ss on my Blackie Build.
