I believe Terry Keeley made some little gauges that slipped through the glow plug hole to check the head clearance. Does anyone have this tool they would part with?

Old school .Use Solder .or use dial callipers
Or,
Contact Daniel place and see if he has any dial gauges in stock. Look up the manufacturer page he will be there .

I second the solder and dial calipers. Always works for me . I usually just feel along the smashed out solder with the calipers and find the thinnest reading and that is where the squish is at.

there's a huge discrepancy between my squish gauge and solder. like over .005"

That’s kind of what I was seeing myself last night it doesn’t seem to be super accurate

I would not use solder. Especially if you’re running tight clearances. Either measure it out or get a clearance tool.
If you’re running .010 or lower it is very important to be accurate.

Solder for me, used it for many years. Get the solid type 0.030 diameter.

Depth mic works for me for 39 years.

just throwing it out there that you can use the backside of a caliper to take depth measurements.

Depth micrometer easiest, most accurate method for setting clearance. Highly repeatable, measure deck height at TDC, measure button from touch-down surface to squish band, subtract difference....usually a negative (interference) sum, determine shim thickness needed for desired clearance.
Using used shims (pre compressed) a smidge more accurate, by maybe a couple of 1/10000"....not a big deal.
This isn't rocket science.

When I use the rod in the caliper to do that though I always wonder if I am perfectly flat when I push down and so I do check that way too but I confirm with 30 thou solder and sometimes I even rotate it a couple times over on the same solder and it seems to just smash to what it can smash too. I guess I really just don't think to much on it anymore just get er done and go running.

This is just a decent caliper with a base attachment. 3D printed stand to hold the motor vertical.

Yeah, that base is the key.

The head button surface seems to be angled not flat as well. I have no problem on the cylinder side with a regular caliper, it’s the head button side.
