Sputnik tools jig

Haven’t come that far, but as I’’m metric as well I will probably come to this. What exactly was the problem?

I heard that the sputniik was short for the longer bikes now.
Do you know if he changed the design so longer bikes can fit. This maybe an old problem address many years ago.

  1. The scales on the fixture are metric. Why are the bolts imperial?
  2. I think in metric for everything except milk, petrol, temperature. Having to switch between the two is just an annoyance. If I look at a bolt I’m going to think 15mm not 5/8" (15.88mm) or 6mm not 1/4" (6.35mm).
    3.At the old shop we had segregated + color-coded tools (American cars + tools were on one side; imports were on the other).

This is more of me being a grumpy ass more than anything else but I still find it to be a minor inconvenience. I suppose that I’d feel differently if I had an imperial mill + lathe.

It’s been like 2 hours between “I don’t know what you are talking about” and “sh… I have no idea what this bolt is and I don’t have a tap like this so I can’t make an attachment to my stand and putting a M10 bolt instead does not work because it’s too thick”… I have only started using imperial stuff (or actually be aware of and care about) when I got into bikes. Here we have imperial numbers only in some plumbing and pneumatic stuff for some unknown reason.

X + Y points for the Sputnik are measured at the bottom of the head tube. They’re both specced for 555mm. Here’s a quick idea of what that might translate to.

Congratulations! What an exciting piece of equipment!

How’s the jig working out? Have any more pictures with it all set up?

Well, after almost a year:

  • the jig is nice
  • imperial bolts are truly annoying, I needed to buy an imperial hex wrench set only to use it with jig’s bolts
  • BB post does accept Paragon made BSA BB’s but there is a problem with EU-made: they are within the standard, but dont fit on the post as it is made with very tight tolerance (and probably using Paragons’ ones as benchmark).
  • a few minor issues like some holders positions I’d tweak
  • properietary dummy axles (they are nice and hold stuff very rigidly, but - all the other tools I have use Paragon/Academy ones so I have to double everything)
