jim stewart was the one who made them for scca. it's been almost 2 years since he's passed on. to my knowledge, there is no one making them.

Seems like Mazda would be a good seller of these 'tools'. AWR or another vendor could fab them.

Doesn't identify the tools, but does show the process by a Pro Engine Builder, measure process at approx. 47:30

Naw, your air tube is more dust covered. I knew whose car it was but a case of CRS took ah hold. Jim, you like that CRS.

i would reach out to rick harris from scca to ask him directly for assistance on this.rharris@scca.com
Jim did not actually make the tools at his shop. He had a company he uses make them. Not sure who that company/shop was, but that is how it went. Be nice to find them, but no idea how that would happen

James, remind me what year car you have.
I believe he has an NA 1.8 and a 99

Interesting video. I would suggest that tech use something other than harbor freight calipers though.

Steve, need them for na1.8, nb 1.8, and vvt cars.

Have you ever tested the cheapo digital calipers sold at HF? Between home and the shop I have at least six of them in three different sizes. Using calibration blocks from a micrometer set, of those one is off by about 0.0015 after zeroing and the rest are FAR more accurate and consistent than I would expect for the price. HF definitely sells some junk but they also carry some genuine value depending on your needs.

and .0015 variance is a far tighter tolerance than many using the tools

My writing skills (as Denny reminds us) may be a tad off/confusing, but with micrometer can repeat measure to a tenth 9 plus times out of ten. Then if one throws out the high and the low, BINGO on being exact. Unless of course if one uses a 5 place micrometer.

Here is a test of the calipers with comparison against a set of machinist quality calipers fwiw:

Alberto, the link doesn’t work for me. How about a summary?

Hang with Pierre for caliper comparison.
No repeatable comparison because even with a high $$$/quality/parallel jaws caliper, it's all about cleanliness and thumb measuring pressure. Has anyone ever viewed/used a caliper with a sliding spring force load device for a constant pressure.

Well now, since we're discussion caliper parity I want to jump in. Biggest issue with dial caliper is the tendency to measure everything at the tips which cause excessive wear. You have to calibrate along the whole length to check for wear. The cheap HF type tools will likely wear much quicker because of cheaper materials. NIST practices like to see a tool have accuracy of 1/10 desired tolerance. If you're trying to measure .002" a micrometer would definitely be better.
Arguably this is overkill but I haven't posted in a long time and I actually work with stuff.
