paulnaz Posted September 7, 2020 Share Posted September 7, 2020 It does have the appearance of a "pre-production" tool, (homemade). Have you used this for it's intended purpose?. I checked my K75 tool kit and that part was not included, my second stab would not only be a wrench, but also a gauge of some sort. Paul B Link to comment Share on other sites More sharing options...

Paul B "Pre-production" . . . I like that! This just appeared in a tool roll on a salvage bike. Not sure what it is. It was slipped in the little pocket of the tool roll, so looked like "it belongs." Kinda reminds me of a float adjustment tool, but not entirely. And there is no saying it is actually for the K75 it came with. Could have been for the guy's Coleman camp stove! 1 Link to comment Share on other sites More sharing options...

Any idea of the size of the hole drilled in them? Have two vacuum gauges and am constructing a bush mechanic carb balancer. Link to comment Share on other sites More sharing options...
gstallons Posted September 7, 2020 Share Posted September 7, 2020 I'm sure you could go with a 1/8'' dia. hole and see how it works . Link to comment Share on other sites More sharing options...

I'll walk down to the shop and get my welding tip cleaners to use as a gauge.. Edit: Ok, I'm back. Hope you have a really small drill set.

Edit: Ok, I'm back. Hope you have a really small drill set. Mine is .018". Thank you! I scored a couple of new 270º sweep vacuum gauges for $3 and change at a local surplus outfit. Their destiny was immediately apparent to me. 0.018" you say? Well, I have some Keihin jets from a couple of Kawasaki jet kits that I can slip into the hose and try. Kawi pilot jets are even smaller than that - 0.014" IIRC. I have mercury sticks, but I am somewhat ill at ease knowing that it could be ingested with one of my ham-handed slips of the wrist. Thanks again - it gives me a baseline. Link to comment Share on other sites More sharing options...
Lucky Phil Posted October 7, 2020 Author Share Posted October 7, 2020 Another of my Grandfathers old tools. I've had it for years all covered in surface rust awaiting a refurb which I got around to last week. The bluing didnt turn out perfectly but thats ok as it adds to the patina a little. I believe its for use as a marking out tool on a surface plate? Chuck might be able to fill in the details? Starrett made in England and I'd guess somewhere around 75 years old, maybe more.

paulnaz Posted October 7, 2020 Share Posted October 7, 2020 Very early Height gauge and yes, used on a surface plate. Cool tool even if it"s just for display now. Paul B Link to comment Share on other sites More sharing options...

Paul B Sorry, it is a *surface* gauge. You can measure height with a height gauge. I have one out in the shop, but I'm too lazy to go out and take a picture. A surface gauge is not obsolete.. it is still as useful as it ever was. 1 Link to comment Share on other sites More sharing options...

I've also found out with the addition of a V block its good for locating the centre of any round object. Also for getting a piece set up close in a 4 jaw chuck.
