Just though i would add that i'm not using any fancy machinery for this project, just a 15 year old b&q benchtop pillar drill and the cheapest vice i could find in machine mart. (about 8 quid)

No reason why other radsters couldn't have a go :daumenhoch:

Likeing the look of this. :daumenhoch:
My only concern would be the seamless look, Would be OK on a carpet queen, But wouldn't fancy riding it.

So with the drill bit in place it dawned on me that the little pillar drill may struggle removing so much material and a good quality hole saw would be a much better option.




Nevertheless i pressed on and just took my time with it.  :)



It took around 25 mins  :LolLolLolLol:

was thinking the same thing - won't there need to be a little gap so you can clamp down on the bars better?
looks ace flush, but can see the bars slipping if the 2 parts of the stem are completely flush...???

At the moment there is a gap of around 2.5mm between them. if it needs to be bigger I can file one of the internal faces but looking to have an almost seamless gap once installed on a bike  :D

Cool, yeah have seen that. :daumenhoch:

Had a similar thought myself a while back then they turned up with that. Glad i didn't persue my idea now as i believe it took them a few prototypes to get it right  :)

I looking into cutting fluids and alot of the yank references were talking about using kerosene.
Used the missus sewing machine oil in the end which seemed to work well  ;D

Bollocks!, just though while typing this, i have about 2 gallons of paraffin in the shed from the days of the allotment green house heater.

The dreaded tax return and a couple of customers got in the way of progress today  :(

Still managed to square off the bottom of the bolt countersinks and drill the top cap to house a Potts mod bolt head  ;)
