Riser blocks, or just blocks?

[Steve BowerParticipant @stevebower42241]

I've a Super 7 just acquired & am looking to set it up. The lathe is mounted on these:

Are these 'riser blocks' or just 'blocks'? Should I get a set of the ones with the adjustable nut? Ta

The older Super 7 on Industrial stand was fitted with plain blocks, and adjustment was via the cabinet feet or by shims. The "octagonal" stand was bolted to the floor and the blocks had adjusters. The Industrial stand is of course much more heavily built than the octagonal.

If you want to convert your plain blocks I have a set of adjusting nuts spare. Will have to check thread, seem to remember its a bit unusual , though it is BSF. May be 9/16".

I've the industrial (roll-edge) cabinet, but think that the adjustable locks would help 'finesse' any alignment (not checked yet). Would your nuts be a simple fit or would I need to drill & tap to suit?

Cut U shaped shims and slide them in around the mounting bolts in situ to do the alignment. No need for adjusters.

That's how I did mine, riser blocks made from sawn off lengths of 2"sq bar. It's more permanent than adjusting screws which can always come loose over time

There is already a hole, but too small for the adjusters. Need to drill half depth of the block and tap to suit the adjusters. I'll go and check the thread, forgot all about it this morning when I did my "Early prowl"

I did have a sketch but can't find it in my albums.

[RobboParticipant @robbo]

Adjuster thread is 9/16" x 16 tpi BSF.

Found my crude sketch of bolt and block. Obviously I did this in a hurry for a visitor who was anxious to leave. I have that effect on people.

When I got my S7 I knew there was twist in the bed so fitted adjusters as the easy way to get rid of it, as the previous owner had them so I knew how much turn from zero I would need to get a parallel turn. (He was the second owner).    I don't claim they are the easiest or best way, just suited me.

Since then I have altered plain blocks for other people – mainly because I was the one with the 9/16 BSF tap!
