Tractor paint interesting me. Anyone got/willing to upload a tractor paint finish close up ? Particularly if brush painted. 20200525_103413.jpg The underside of my newly painted rack. Its probably the worst bit of the rack, and there's areas where I didn't maintain a wet edge, so new paint went ove...

Re: is there any such thing as tough DIY paint?

Several years ago my hack bike frameset showed its displeasure at my continued use of it by breaking. At which point it became clear to me that it was no longer something which would be easy to replace, having seen more than a few modifications etc over the years. At heart it isn't anything super s...

Re: is there any such thing as tough DIY paint?

...The other option is to consider that all paint will get chipped and scratched eventually, and that there will be times when certain areas will need repainting (top tube, front forks, chain stay) every so often. So rather than buy an expensive paint to begin with, what we could be looking for is ...

Re: is there any such thing as tough DIY paint?

This time nearly all the old paint will have to come off, because I've somehow ended up with incompatible paints on the frame; some combinations only work if they are in the right order and in places where the paint has been repaired, the layers are in the wrong order and there is lots of paint cra...

Re: Selle SMP saddles

Yes, I've got four TRK models. One on my bike and the others are spare - they tend to come up for sale second hand on this forum's 'parts for sale' page. I have to admit that they work (and that's a statement that needs no follow up questions)

Re: Moulton TSR rear pivot

I believe there are two sorts; plastic matrix with bits in, and metal matric with plastic in. The former are probably not strong enough for this job. cheers The oil impregnated plastic industry say that older engineers often say that... it's worth checking out their websites and plying them with qu...

Re: Moulton TSR rear pivot

this bush sees high loads when it is static or almost static. This means that any film of lubricant will be squeezed down to nothing (so metal to metal contact is almost guaranteed) which is why I think you need a grease with a high viscosity base stock and solid lubricant additives if you want to ...

Re: Moulton TSR rear pivot

Stupid question three, Would it harm the service life of the bushings if a very shallow (in depth) spiral channel was cut into the inside face of each bushing (where the hollow spindle meets it)? Such channel may allow the grease to reach every part of the surface and could at as a reservoir during ...

Thanks for the diagram.... its explained alot, but it has lead to my next stupid question...

Re: Moulton TSR rear pivot

Apologies - today's stupid question is,

When the grease is forced through the grease port, does it then flow between the frame and hollow spindle or does it flow between the frame hollow stainless steel spindle and then into and then along (inside) the hollow spindles well?

Re: Moulton TSR rear pivot

Well ................... Doing some fixing and tinkering with my Moulton, and had a feel at the rear triangle, and felt a very slight play in the pivot. Put grease in there, and it's gone ................. for now. The pivot has been greased lots since I fitted the new bushes. Mileages between grea...
