My lathe

Do you use that dial test indicator holder as a length stop as well?

The whole set up is very classy, I've been thinking of doing something like this to my machine too.

I use the dial manly for measuring a part but it does stop the cross slide from hitting the headstock

I like the clean design for the dial indicator holder and easy to adjust for maximum range of the DI. I did something similar for my old Unimat SL 1000 lathe with a 3" swing. I posted the overall lathe view photos at

and the dial indicator details at (x-axis has analog 2" range and y-axis has a digital 1" range).

Your design is nice and I liked your quick change post
Very smart design

Thanks. The lathe improvements have been a fun project. The QCTP has been very useful for switching between HSS and carbide insert cutting tools. Recently, I have been making more tool holders for the QCTP using a 60 degree dovetail cutter I purchased from eBay. Here is the link to the finished tool holders

Tonight a started a new machining project to build the compound stationary marine steam engine based on the plans from "The Shop Wisdom of Rudy Kouhoupt". Just finished the layout of the upper entablature using my surface plate and a digital surface gage (an early Christmas present). I hope to post the photos as I progress.

Very nice and clean
So what kind of steam engines are you working on, I've build them as well

This new stationary steam engine project will be for a small compound marine steam engine model that can run on either steam or compressed air (but compressed air requires different lubrication techniques). I just finished collecting all the raw materials so I am ready to start building. The plans and photos are from the first book in a four book series “The Shop Wisdom of Rudy Kouhoupt”. I own the books and I made copies for my shop notebook. The only parts I won’t make are the stainless steel threaded rod materials and nuts. The finished engine will weigh about 5 pounds and fit into approximately 3”W x 5”L x 6.5”H space. The two cylinder bores are 0.875” for the high pressure side and 1.250” for the low pressure side and both have a 0.812” stroke. The reversing valve gear is based on a Stephenson’s link motion. The engine is self-starting except for one very small potential dead spot which is highly unlikely but can be overcome by temporarily supplying high pressure steam to both the LP and HP cylinders using a manual bypass valve (or just rotating the flywheel by hand).

Here is the first build photo showing drilling the holes in the entablature that supports the cylinders. I use the x and y axis dial indicators to locate the holes (after manual layout on a surface plate). My x-axis dial indicator has only 2" of movement and for this part I need around 4" of measurement. I can overcome this limitation by using additional extensions from a dial indicator depth gage (just have to keep track of the 1" or 2" offsets). By the way, in this case aligning the vise precisely is fast and simple because of the vise side clamps I made for this purpose. It takes around one minute to set the alignment to within 0.0005" across the vise fixed jaw. I included a photo of the alignment process. The vise clamp info can be found at http://www.homemadetools.net/screwless-vise-clamps-2.

Looks great like the base with draws
It is also space friendly

Thanks it was fun restoring and I'm very pleased with it. A very accurate and powerful machine for it's size
