There are about three different normally used tripod thread sizes. 5/8"x11male, a 3 1/2" male thread and a smaller somewhat proprietary about 5/8" fine female thread. For your laser level of fairly recent manufacture I believe is 5/8"x11.

Just for info, older instrument manufacturers used their own thread size so you bought their tripods.if curious a browse at a U.S. manufacturer Chicago Steel Tape should show some current sizes.

At the bolt supply company I worked they were called tap bolts.

A method I use is to assemble vertically. Put the nut on the scriber shaft holding it wiithyour finger and apply the point to the end of the threasd and let go of the nut leaving the scriber on the end and in small circles twiddle the nut into place with tthe scriber pount, it will self start.

Great respect for your accomplishment! I have searched for small screws in office carpet.

Literally almost down the drain. My most miraculous save was when servicing an obsolete microscope at a medical clinic on their countertop. I was reinstalling a 1mm slotted set screw when I dropped it and I heard it hit in the stainless steel sink about 18" away. I picked it out and the same thing happened but an immediate search found nothing. A second search found it in the small ring of water surrounding the drain, disaster averted.

As on my cimouter todat. Savior heated gloves. Pricey.

Fungus growth usually creates more of a fog effect with permanent etching. I have had lenses with a pattern similar to yours that were described to me by older experienced technicians as a glass eating bacteria, usually from instruments stored in a damp high humidity area. Extreme cases looked like a vine pattern nearly covering the area.

I have had success with Greased Lightning household cleaner. It can also go down the drain. It is safe for plastic and glass but heed the warning about use on aluminum. In normal cleaning on aluminum it is fine but do not put the object in jar as it will eat away the material, that being useful to strip anodizing from a surface with careful use.

As a microscope service technician I used cotton swabs by the carton. As an amputee I guess was wrong.

In my experience survey markers are called monumentation. I searched for Ordinance Survey Monumentation and found several pictures similar to the one I have included from the U.S.

I have experience with optical instruments. I see you have assembled the components except for the spindle mount. the current image location could give you an idea of the adjustments needed. I would lock the eyepiece in place in the tube to eliminate movement. I would also Lac the reticle in. Some eyepieces have a wire ring to hold it in, some have push in type holders some have screw in type holders. I have seen some where the reticle would rattle in place if moved. Clean the reticle well on the eyepiece side prior to setting in place. Depending on the quality of the reticle there can be small black dots on the photoetched side that are not removable. The photoetched side goes toward the eyepiece. If using a small compressed air can hold it upright pointing up to avoid the liquid propellent being sprayed on the surface making a worse mess than you started with.

It looks as if your prism mount slides in a round hole and the fit will effect the adjustment. I would put adjustment screws in for left-right movement and up-down movement. If your image is satisfactory that may be all that is needed. A second set would give an angular adjustment pointing to the left or right and angling up or down.

As a officer I was on patrol with a partner slowing down turn into an after hours bootleg joint. We were struck from behind by a drunk driver doing about 65mph. The driver had been drinking because his brother had been shot. I was injured and off the street for a few months. The driver didn't show up for court and a warrant was issued. One day he when in to court and the judge held trial right then giving him affine and probation.

A few months later I was working a section of the tactical unit dealing with street level narcotics, My partner and I had a assistant county attorney riding with us and we saw two people at the curb making a deal and the vehicle drove off. we got out and I took the one on the left who put his hand behind his back and after telling him to put his arms out his arm began to rise behind his back. I was convinced I was about to take a round. Already having my weapon out I kept yelling and he put his arm down and I had him lay on the ground. I put one foot on his hand and a knee in his back. With my gun poked in his ear I pulled a pair of brass knuckles out of his back pocket. That is what he was doing and nearly died for, putting them in his pocket. I asked him his name and he told me, It was the drunk driver. I did not recognize him. I was angered to the limit. Other officers had come up and I had them take care of him. Within the previous week I had told someone I wanted to have a piece of this guy and to tell him what he had done to me.

A lot of people say a lot of things until the moment comes when you are given the opportunity to show what kind of person you are. Thankfully I did not have to fire then try to explain I didn't know him, and the county attorney would have been the best witness if I would have. He was taken to jail for the brass knuckles. I had to ride in the back seat with him to jail and booked him. He still does not know it was me.

People will continue to drive if they can get behind the wheel. Some will straighten out, some won't.

I had a call on my cell phone I did not recognize so I did not answer. They left a voicemail with callback number. It was for an arrest warrant and I needed to pay or be taken to jail. I called them back and heard background of young kids and a voice of a minority individual and when he repeated the same thing I told him it is hard to believe that my police officer partners would let that go by. A second of silence and click. Obviously a beginner and probably needs to work on his scam, I mean really, a callback number?

If the lens is held in place by the tube screwing in you may try a method I have used for field repairs. Put a piece of tape over the eyepiece cap outside and press against the lens through the hole. Screw the tube in place and remove the tape. The tape could leave some residue to be cleaned off.

My apology to Mr. Pavey. Mr. Gillligan, I stand corrected for exceeding the bounds of the original question and can assure you I will not be a problem in the future.

I would reconsider having it around. It can do many jobs other than watch size pieces, such as screws, pins, etc. A sewing machine motor is not expensive and you might find after playing with it for a while to keep it. I have a couple Unimats for such work and it is easier to do small jobs on them and a nice sit down table job is sometimes a relief. There are three jaw chucks available or adapters for them from Sherline that can use other chucks. A possibility as a house lathe with new belting and the motor even without the countershaft as a board mounted setup.

The book "The Watchmaker's Lathe, It's Use and Abuse" by Goodrich is a good overview of the development and accessories.
