I ask out of 100% self interest. I have a 1970s Viscount bicycle for which I need to buy at least one bolt. The thread is English and only available here for a king's ransom, if at all. I'd like to have a "friend" on that side of the pond who'd help me obtain them. I'm perfectly willing to not only cover the actual cost, but also add remuneration for the effort involved.

Same for me Animal, but down here in Australia the Brooks seats were very expensive and I went for a leather covered nylon Italian made seat. It was terrific and need a lot less care and attention than the full leather Brooks.

Re: Southbend405

Welcome?
I am a former owner of a 405.?
The ABC spindles will physically fit on the diameters but there’s an issue with the length. ?
I don’t remember exactly what but I believe it can be over come. The ABC spindles are longer as I recall.?

The 405 has entirely different felts.?
They are cut into strips and fit into slots in the top of spindles.?
It’s important that they be continuous and clean.?
There is no oil well in the bottom of the spindles, like the ABC, so they must be oiled at every use.?

There shouldn’t be much more information in the files section.?

I have replaced all of the cross/compound feed nuts added the needle bearing fix for axial play an re machined the original 1 3/8 10 back plate to fit a nice bison chuck and added an aloris axa tool post.

Re: Eliminating the step pulleys

They are dual v-belts.? The crown is still there. They tend to stay in the middle until heavy load is applied.? The flange will hit the top of the v and yes will occasionally wear the outer belt edge, but the bottom is doing the driving. ?It doesn’t get a lot of use right now.

Rick, if you add a flange to stop the belt wandering off, it will chew the edge of the belt, and the belt might even climb onto it. ?Flat belts need a crowned profile on the pulley, and you should check whether yours still has this. ?Compare the step in use with the others. ?If only one of the speed pulleys has been used for an extended period and there has been some slippage, it is possible that the pulley is worn hollow. ?So long as there is some metal left, you can machine the crown back onto it. ?I've never tried it, but a coat of hard epoxy filler might make up any material shortfall.

All counter intuitive, I know, but that's how they work.
