I'm glad you liked my design, thanks a lot.. and bdavanza has all the key questions.
So i took these pictures for you bdavanza , i think they will answer your questions..

In my previous post you saw just the mock-up of my set-up.
The picture below is final and assembled. You are not going to see any welds, its all hidden underside.



You also see the steel spring seat which will protect the brass spacer, it has the same continous taper form and holds the spring in place.



The steel seat can be internal threaded or just kept in place with a cotter pin.



One item that is not in the picture is the leather gasket that will be under the brass spacer.

is the pin all that will be welded? then the brass used as an accent/spacer? Or will you braze the brass to the steel collar?

Either way inspiring details

Yes, the brass spacer will stay like this, no brazing here, this way I keep the clean look.. What about you, now you're looking for a triumph project?

Any idea on the shearing force created by the downward motion of the seat? simply will that pin bend at the weld with the seat pressing down and back on it? I see it's undercut to build up weld and get the penetration, another thought would be chamfer the inside of the brass spacer and use a plain round rod then build up a filet weld where the chamfer will clear, should create a stronger joint.

or further still, countersink and chamfer the brass spacer and turn a rod with a larger OD on the bottom to distribute any forces over a wider area. Sorry the engineer side of me comes out.

Not to Hijack but yup may have found a candidate, this is for after the ironhead but a build on this motor that i haven't seen before i think will look really cool.

Have you seen the original spring mounts on the rigid triumph frames? Mine is kind of similar, I basically used the same dimensions, but instead of an external welded collar my rod runs through the frame directly.

And actually, the welds around the rod extend to 1 of a diameter and tapers upwards. So like you mentioned I had to countersunk the brass spacer to have a perfect fit, this added even more strength to my set-up.. What makes this design unique is that there are no exposed welds/braze, I can always adjust the dimensions of the components according to the needs of the project..

Appreciate your input inkmunky, looking forward for more updates on your ironhead..

I get it now, i didn't know you were going through the frame with the rod. Should hold up awesome that way, glad to see some people thinking stuff through!

Looks great keep it up!

Hey astek, if it's possible I would like to see how you cut the fish mouth on the brass pieces, they look so clean...

You do some great work, Dan

Within the last three days I built the clutch lever assembly. I designed and made it from scratch but kept the approximate standard geometry plus a safety ball. It seems to work very well..
