Axminster/Sieg C0 Baby Lathe Compound Toolpost ?
|
Hey guys, another slightly off-group post. Sorry. It is lathe related though so please forgive me ! :) So i have an Axmisnter/Sieg C0 Baby Lathe and it came with a compound toolpost that is supposed to allow you to set it for cutting tapers, chamfers etc. You basically need to remove the existing toolpost and put this on on in its place. Its simple enough to do as the toolposts for these lathes are secured via a simple tee nut. The compound toolpost locates in a circular recess above/in the t slot and rotates around this pivot point. However while there is a, kinda, index of the degrees screwed onto the rear of the toolpost dovetail there is no corresponding 'Zero' mark on the crosslide to set the toolpost too ! So how do i set it up to some arbitrary angle like 25 degrees ? Its available on the index but what do i reference it too ! ? Hope someone can help. Cheers and Kind Regards.

A common "weapon of choice" is a machinist's protractor.? It is one of the typical items you might find in a machinist's tool chest. Square head: Or Round head: You reference surfaces on the tool post to other parts of the lathe, work piece, whatever as needed to determine the angle.? It is usually a good idea to use these on Chinese baby, micro, or mini lathes in any case because their markings are notoriously inaccurate anyway. Once you can set an angle using a machinist protractor (and there are other angle measuring devices out there and some of them more deluxe) you could set it to zero and carve in a zero mark.

Take a small adjustable machinists square, hold it on one side of the cross-slide with the end of the blade about 1/2 way across.? Use a fine tip marker along the end of the blade and make a line.? Now take this machinists square, flip it to the other side. and mark a line again.? You have now found the center.

Now when you want to make a nice center line on the cross-slide, paint the top with blue Sharpie or similar.? Repeat the procedure as before, except you are now just lightly scratching a mark with a very fine point scriber.? Do this carefully from each side and adjust the blade until you mark as close as you can to center.? Then you may use the end of the blade with a heavier scribe to mark the final center line.? If you are unsure, practice on a block of aluminum or brass.? All will be revealed.

The Unimat 3 uses a similar one but there are two marks on the saddle. Maybe you should 0 in the cross slide and add your own. Put a piece of scrap in and turn the length with the crossslide and measure both ends if they are the same that would be zero. Mark your saddle.
