Well as again there appears to be a bit of a gap between updates, but as ever I've been doing things when I get a chance. And after reaching a bit of a milestone this evening I realise its well over due update.
So in between rebuilding the Bridgeport
The Colchester (again)
Some tooling parts
As well as making some more modification to my Grom
I have been hitting the machines as much as I can. Things that have been made include spacers (lots of), toe pegs, foot pegs, and linkage rods.
The pegs are all knurled, the toe for the gear and brake lever were fairly easy, I even found some end plugs for them from the metal suppiler. The main foot pegs were slightly more difficult, it turns out that I had to apply some maths. Thankfully I'm not the only one who makes things, there is a whole host of knowledge out there. In short to get the 20mm peg with the correct knurl I needed to start with a 21.65mm round.
I also used a boring bar for the first time to make the 14.1mm bore for the peg ends. And the linkages have a 6mm left hand thread at one end as well as 8mm spanner flats at 180o angles at each end. With all that done the next step will be to finalise some mounting holes and check that its all going to work, this worries me...
