All it needs is a bit of flat to locate between the 2 round bars, which could be done with file and saw, screwed to  a longer bit sat on top, and a 3rd long bit underneath to clamp it all together. No accurate holes of vees. Don’t introduce spurious accuracy.

You may be ‘technically’ correct there, Duncan … But, as Dave has repeatedly reminded us elsewhere, we should consider needs and wants separately.

If I was making a ‘fixed steady’ for a Unimat, I would want it to include kinematic alignment with the headstock spindle [which makes the job of setting-it-up for work much easier].

Duncans method would give 4 long contact points as would two vees so should keep it lined up. Take a look at a Myford fixed steady, If it works for myford then it should also work for a Sl and give the Kinematic alignment desired.

 

Emgee is that designed for the Sl as it looks like the U3 type but would still have 3 points of contact and work OK if sized for the round bar SL’s ctr height?
