Thread: Mahr Zentimess Oil Change

My new DRO is enroute as we speak, and I have days off starting right now, so I hope to finish Stage 1 of the FP-1 resto and maybe even mount the DRO this week. I could have used the gauge block slots and dial indicators, but I am not a machinist. Not by a long shot.

Bob...I just arranged for a copy of Mike Yamamoto's book from his widow Karen*. It too should arrive soon. I hope to be able to rectify my Tesa dial calipers.

*Mike died last June. Apparently he was quite the guy.

Excellent! So looks like Greg will be doing my dividing plates then

I'm hoping to be in that position this week. On the other hand you could buy a stepper and one of those controllers for your rotary table and forget about dividing plates. I'm sorely tempted to do that when the time comes.

Hmmm, stepper motor 'eh? Naaaah, I'll take the free dividing plates

We are lucky that we have the legacy of his book. When you read it Greg, you will discover that Mike was a master of improvisation. Stuff like manipulating tools made from ground down sewing needles. The white bed sheet on the floor is on of my favourites. Yesterday, I dropped one of the 1mm Japanese balls Jordan "Nadroj" sent me to repair my Mitutoyo. I didn't bother to look for it after hearing it bounce. A sheet on the floor might have enabled it's recovery. I'll post a couple of photos of the loupes I use. This ain't naked eye stuff.

Loupes are something I'd like to know more about. I have a couple, but they are hand held. Do you use the kind you wear?

BTW, I just bought a set of camera/watch/indicator repair tools but have not received them.

Greg,

Search for Behr loupe. I find these the most convenient because they clip onto my glasses. I need to post a couple of photos because there are some subtle differences in some of the Behr frames. Also have a Bausch and Lomb loupe that you wedge into your eye socket. It is a 4X 7X two part loupe. I'll discuss tweezers and screwdrivers tonight.

Greg,

Below are photos of the two versions of the Behr clip on loupe. Ignoring the fact that one model has two lenses, the difference is the little lug (or lugs) that align the body of the loupe on the arm of the glasses. In my mind, the older 2 lug model does a better job in preventing the loupe from being knocked off the arm. Someone who is more careful might not have a problem. New, about six years ago, they were about 40 bucks. I have bought both loupes on Ebay for about half the new price. Behr has a website and they ship worldwide. Don't bother with Bausch and Lomb's version of a clip on loupe. It does not stay on.

The glasses are cheap fixed focal length jobbies from K Mart. They have proven far more robust than my expensive glasses.

The B&L loupe cost $20 "buy it now" plus $5 shipping.

The Bergeon screwdrivers were purchased at lunchtime today along with the stick of Rodico which is used, amongst other things, for removing finger prints from dial faces. The screwdrivers are beautiful. I'll end up buying a few more larger sizes. I bought them at Seiver's. They have a shop in Melbourne located on Level 11, 343 Little Collins St.

The other two screwdrivers are Starretts. I have a cased set of Moore and Wright jeweller's screwdrivers. I got them second hand and unfortunately most of them have damaged blades.

The tweezers are all Swiss. The Erem's were purchased about 5 years ago when I bought half a dozen pairs ( they were on sale at Seiver's for about 6 dollars a pair) to give to my wife and two daughters so they didn't keep swiping the Dumonts for plucking eyebrows.

The bottom pair of Dumont tweezers I've had for 30 years. There are heaps on Ebay. They are superb.

Hope this has been of some help.

It has indeed Bob, thanks you. I am going to buy loupes for me and a friend, and I am going to pay those folks on Lt. Collins a visit. I was about to buy a set of Wiha* precision drivers, having outgrown the El Cheapo set I got in Taiwan back in 98. I'll have a lookee at the Bergeons.

What focal length Behrs do you have? I dislike bringing objects any closer than 6" or so to my face, but that length only yields a 2X magnification.

*I have Wiha electrician's tools and like them j-u-u-u-st fine.

Greg,

The single lens loupe is a 3X ( 3 1/2 " focal length ) and the 2 lens model is a 3X and a 5X ( 2" FL).
