A few years ago I saw this Adjustable V Block in a wood magazine and thought it would be a nice project to build when I had some spare time. So I built one for me and one for my best friend in Illinois but never had an occasion to use it- until yesterday. The v block is for holding a round object of varying diameters and this lamp I had to drill fit that perfectly so I dusted off the v block and set the segments to hold it so the bottom was vertical and drilled the wire hole and the front trigger hole for the lamp.
The v block is made from 3/4” plywood with walnut splines and 3/8-16 threaded rod and a couple of threaded handles for the clamp. The block has 15 layers that are 6” wide and 6.5” high . A llittle WAX on the spines make the segments slide easier( getting all the old dust out does too!!).

Thats really something. Can I ask a stupid question: what about friction? Do you put some wax or something to reuce that?

Cool jig!

What I am really impressed with is that you took the time to build a jig before you needed it! I would have waited unitl I needed it, then forgot about the idea and fussed around with blocks or whatever.

A very simple ingenious fixture that will be very handy to have. I’m favoriting this for a later build. Thanks for posting.

Hi Mafe. I just re read my original note and spelled wax wrong. I do wax the splines to make it slide easier. My fingers are getting sloppy on this keyboard with my old age. I’ll fix the note!
