Thread: Ideal Dimensions of Vice Clamps
29/09/2020 05:41:37

I made my clamps from aluminum. The underside is rebated leaving about a 1/4" heel to contact the table. The screw was located as close to the vise as possible.

Thread: 3/16 Cast Iron Rod
29/09/2020 05:35:13

I have a large amount of cast iron welding rod (R-CI). It is about 3/16" dia. The finish is sand cast and the halve are slightly offset (mold mismatch). I don't see how they could be used for anything but welding. If you need a smooth cast iron rod I suggest you find a larger diameter and set up a hollow mill on the lathe to reduce the diameter.

Thread: Basic threading
21/08/2020 22:29:59

Is your threading tool with a sharp point? That would require a greater depth of thread than a tool made with a flat equal to pitch/8.

21/08/2020 22:25:57

First make a gauge that matches your spindle exactly. Use that gauge to check your internal thread.

The critical dimensions are the length and diameter of the cylindrical pilot and the OD and pitch diameter of the thread. You can tolerate a relief groove at the end of the threads as long as the pilot diameter isn't touched.

Save the gauge to use on future projects.

Thread: Switch gear for 2 speed motor
19/08/2020 23:56:33

I found a coupe on flea bay. Here is a

I purchased one The contacts are rather small so I suspect life will be short if switched between fwd and rev as in tapping.

Thread: Ring rollers
27/06/2020 00:04:12

Check out This Old Tony on you tube. He had a video about building one.

Thread: Shaft Steel Material Selection
27/06/2020 00:00:57

Here is the source of my recommendation:


26/06/2020 23:59:34

From Machine Design Magazine: Surface hardness 58C, 16minRa finish.

Rough machine leaving grins stock. Harden. Grind between centers. Touch up keyseats using a carbide end mill.

Alternative: If 60 case rod is available in the right diameter use it and mill the keyseats with carbide.

Thread: Brazing Oilite bearings
26/06/2020 23:44:45

I have successfully soft soldered Oilite. Being a porous material it could continue to absorb solder as long as I kept feeding it. Needless to say, the the soldered material was no longer oil absorbent.

Thread: Tangential Tool Holder
07/06/2020 01:55:30

When I made my tangential holders I used 12* for side clearance and end clearance for a 1/4" bit. After seeing the quality of finish produced by the round bit I will be making a tsngential holder for a round bit.

Thread: Questions about lathe power feeds.
07/06/2020 01:45:55

I had a Pratt & Whitney 14 x 30 that had identical feeds in X and Z.

My other lathes, 13 x 30 Clausing Metosa and Nardini 16 x 40, had X feed equal to half the Z feed. All three machines had a drive rod for the power feeds separate from the lead screw.

My South Bend 10K has a keyway the full length of the leadscrew. That allows the lead screw to act as a drive rod for the feeds. There is an interlock to prevent the half nuts being engaged when the feeds are being used.

I am in the US and the Pratt & Whitney lathe had a Buck and Hickman property tag on it. I am guessing it was shipped to England in the early 1940s. What surprised me is that it made it back to the US.

Thread: Machine Tool Peripheral Hoists
30/05/2020 23:21:38

I have an old Sky Hook. I use it occasionally to put the vise or rotary table on or off the mill. It is inconvenient to set up. I had considered using it on the lathe to handle the 60 lb. chucks. It seemed like too much bother to lift the hoist into position every time I needed to change a chuck. I had a jib crane that mounts to the receiver for the trailer hitch.


I made a pedestal for it that is anchored to the floor. It handles the chucks quite nicely.

Thread: Workshop Gloves
30/05/2020 23:00:57

I usually work bare handed. I learned the hard way about gloves and machinery. My left hand is mangled due to wearing gloves when using a table saw.

Thread: Long Square Stock
23/05/2020 01:44:22

Oops! I forgot you said square stock. A sleeve that fits the square corner to corner is needed if using a steady rest.

23/05/2020 01:41:20

Tap the outboard end until it runs true. Center drill it. Set the center in the end of the bar, then go back anf true up the chuck end.

Option: center the outboard end with a steady rest before center drilling.

Are you sure your chuck is tight against the shoulder of the spindle? (Only if you have a threaded spindle.

Thread: A polite question - from a beginner :) Drilling a NONE wandering hole
21/05/2020 21:00:25

My way of assuring the hole is true is to pilot drill, then open the hole with an end mill, then drill it out to the correct size. The end mill is short and rigid so it barely deflects. Its square end will not tend to follow the pilot hole. I think of the end mill as a poor man's jig bore reamer.

Thread: Internal threading question
21/05/2020 20:49:17

Check the size of insert used and confirm it is capable of the 2mm pitch.

Thread: Annoying milling cutter diving into the work
20/05/2020 22:41:48

Check the recommended tightening torque for your collet. As I recall the ER16 should be tightened to around 100 ft. lb. Also consider a ball bearing collet nut. It gets a lot more hold on the tool shank than the plain nut. I know I seldom get the proper torque on my ER32s. It would involve using cheater pipes on the spanners.

Thread: Insert facemilsl, correct use on hardened Steel.
20/05/2020 22:31:32

It may not be the pocket that is bad. M tolerance inserts have a .002 to .005 inch variation. Check the inserts as well as the pocket.

Thread: Look what I Found
20/05/2020 22:19:56

After I bought my first hammer drill I gathered up all the star drills in my possession and binned them. I do have an adapter for an air chisel to take the A taper bits. I haven' gotten around to pitching it. It is free to anyone who will pay the postage.
