Big Horn 19053C 3 Pieces 8-Inch Spring Caliper / Divider Set

Each of this set of 3 has been very useful in wood turning projects. Easy to set, with springs strong enough to stay where they’re put. Good tools and at a good price.

I'm using mine while working with a wood lathe so the ends being a little sharp on the outside and inside calipers isn't ideal but that's nothing a little filing cant fix.They hold position well even with me pulling them out of my pocket and dropping them back in many times while working on stuff.Having owned these for a couple of years now I can say I've had no problems with rust except some tiny bits on the blackened parts. An that's with them stored in my apron pocket often filled with wood shavings from green wood so they get some fair moisture exposure. I see other reviews saying that theirs got a little rust so it can't be stainless but remember even stainless steel will rust if its exposed to overly rough environments or the surface gets too roughed up so your mileage may vary depending on what you are doing with them.Overall I'm very happy with them and might buy a second set so I can leave some set to more of my chuck sizes without having to re-dial them in.

These calipers are great, for the price, but needed a bit of cleanup before use. They arrived covered in a heavy oil and in sealed plastic bags, to prevent rust from exposure to uncertain shipping and storage environmental conditions from their country of origin. The country of origin is not marked on the calipers or their primary packaging.They do not appear to be made of stainless steel, so I degreased them and then sprayed them with a "dry" lube -- similar to "Dri-Cote" or "Top-Cote". I use them for woodworking and do not want "wet" oil or grease to contaminate my workpieces or my tool chest.The pointed ends of the inside and outside calipers had substantial sharp burrs -- i.e., the tips were ground but not finished. So, I used a hand-stone to remove the burrs and concluded that these are made from a relatively soft mild carbon steel. The springs appear to be made of a harder grade of appropriately tempered spring steel, and the adjusting screws also appear to be made from a harder steel.With proper care and storage, these instruments should do a fine job for a long time, and are great for their price. I did not rate these at five stars due to the amount of cleanup and deburring that I had to do. If I did not already have a hand-stone, degreaser and dry-lube in my shop, I would have rated these at three stars.

Very important they worked very well with the spring system that they had, even though they did not give you a degree in measurement, you have to take a secondary measurement device and be able to subrogate the measurement to what you were looking for, the durability and accuracy was quite markable, but you do need a second measuring device to ensure that the degrees that you are looking for specially if you are doing machine work clean. Thank you, bert

Very happy with these instruments, work very well and easy to use with one hand. Excellent quality and a good price

pleased with the calipers - adjust ability is very sensitive, very stable -- what i needed for a good price

These drift a bit and are a bit rough to use, but they do work, probably enough for most uses. I wish the ends were just a little smaller to fit into the milllwork figures I am recording with them, but that's how it goes sometimes. For the price, not a bad deal. If you want super precision, these are not for you.

A rather crude set but gets the job done. Adjusting the sizes is hampered by rough threads but works ok. The metal is corroded in spots so probably not meant for use in wet areas and must be occasionally oiled.
