Thread: Odd sleeve
05/01/2020 02:40:47
Posted by old mart on 04/01/2020 21:23:35:

Its made in Iowa, so it could be anything. I notice the name is "use em up", I wonder if it is designed to salvage scrap MT3 tapers by grinding a flat on them? It could be worth asking on The home shop machinist forum.

Careful! Some Iowegians get testy over stuff tile that. If it came from Iowa it was probably made by Collis. They were called Use EM Up sleeves. When the tang twisted off a drill or the taper got too messed up to hold in its socket you could grind a flat on the side of the drill shank until it fit in the Use EM UP socket. I am 82 and have only seen maybe 6. Not common anymore.

Thread: Stanley Blade Lathe Finishing Tool

I think carving the knight using the band saw has a lot more potential for injury than scraping with a knife blade.

Thread: Enlarging pulley bore
19/12/2019 21:36:38

Those die cast pulleys are pretty cheap. You might consider buying one with the correct bore. How much is your or your soon to be friend's time worth?

Thread: Slight repair required
19/12/2019 21:30:55

I would use oxy-acy using cast iron rod and ferro flux. Normalize after weldinf.

Thread: Toolpost dilemma
09/12/2019 00:51:25

I have two lathes fitted with Aloris clone tool posts. An advantage to Aloris is the availability of extra tool holders at relatively low cost. The Aloris design is quite tolerant of variations in tool holder dimensions. The Dickson tool holders are more expensive to make than Aloros clones. The Dickson tool holders require the C-C distance of the Vs to be exact for it to fit the tool post.

My vote is for Aloris or its clones.

I have a Dickson tool post and 3 tool holders. It sits on the shelf and will remain there until I need a tool holder of larger capacity than the Aloris provides.

Thread: More evidence that the world has gone mad!

They are all crazy except you and me. Sometimes I wonder about you.

Thread: Another - What is the correct name for this
05/12/2019 03:43:56

It could be either a planer gauge or a shaper gauge, depending on the size. Some were furnished with a scriber that fit the moveable part so it could be used for marking out. Occasionally I use mine with a sine bar. I set it to dimension with a mike, then use it under the sine bar instead of a stack og gauge blocks.

Thread: 1 inch reamer
05/12/2019 03:38:01

The standard taper for 1" reamers is 3MT. Instead of turning down a 3MT to 2MT consider buying a straight shank reamer and turn the end of the shank to a diameter that fits your chuck.

Thread: Turret drill
05/12/2019 03:31:49

It looks like a clone of the US made Burgmaster.

Thread: Case Hardening
05/12/2019 03:26:24

Case hardening is a time sensitive process. The longer you hold the part at temperature during case hardening the deeper the case will be. The compounds like Kasenit or Cherry Red will give a very shallow case due the short time the metal is exposed to the compound.

Thread: Extending an M16 thread.
02/12/2019 21:41:50

As a 17 year old I chucked a tube too tight and deformed the end. It had a 40 tpi internal thread. I needed to pick up the existing threads and re-cut them.

If I could do that as a 17 year old with almost no shop experience, you can surely do it on an external thread. Good lighting and a magnifier help. Eliminate backlash in the half nuts by using the feed handwheel to preload the carriage against the direction of travel. Adjust the cross slide and compound until the tool is centered in the existing thread. Then back out the compound to the major diameter. I assume you will be flank feeding using the compound. Then go at it.

Thread: View on this milling machine please
24/11/2019 18:25:58

They were sturdy and well constructed. If not badly abused it should be a good machine. I am not certain this has a quill. The absence of quill feed (either manual or mechanical) can make some operations difficult or impossible, like drilling a hole at an angle. The tooling offered with it is truly impressive. 40 taper tooling is relatively inexpensive and widely available.

Thread: Positioning bushes for welding
17/11/2019 18:19:41

My preference would be a bush with a shoulder on the OD to set depth and squareness.

Thread: Extending router shanks
13/11/2019 20:22:27

Please don't try to extend the spindle. At the 20000 or so rpms there is not much tolerance for imbalance in the extended cutter. I chucked a fairly long mounted stone in my Makita die grinder (20000 to 24000 rpm) Dur to the overall length of the stone and the imbalance as soon as I hit the switch the shank of the stone made a sudden right angle bend just outside the collet. It became really exciting. I needed both hands to control the grinder and could not reach the toggle switch on the back of the grinder. All I could do was kick at the cord to knock the plug out of the socket. Eliminate the dust shoe and use standard tool stickout. Tolerate the extra cleanup to prevent the potential damage and injury if the extended becomes unstable.

Thread: Allchin Gears- thinking of using pre-cut chinese
11/11/2019 18:39:53

Recently I bought 3 gears to replace the missing change gears on my Nardini lathe. I searched on eBay to find the best prices. The 40 and 100 tooth gears came from Chinese vendors. The 127 tooth gear came from the Netherlands. I was amazed at how inexpensive the gears were.

Thread: 2 point steady identity
09/11/2019 21:27:43

It is for an OD grinder.

Thread: Tools of unknown types.
29/10/2019 00:41:46

There a lot of similar collet chucks on the market. They are definitely not ER type collet. They resemble Acura grip or TG collets but my not be compatible with either system.

Thread: Jacobs model 6414 chuck - removal
27/10/2019 21:50:17

That model chuck is probably the worst Jacobs ever designed. It was used primarily on "home utility" drills. Replace it with a real chuck, either keyed or keyless. Your chuck appears o have a male thread for mounting. Most chuks have a female thread in the back. I think it is a 3/8-24 thread. A short piese of threaded rod is all that is needed to adapt the newer chucks to your drill.

Thread: Stripped thread / Pultra P type
22/10/2019 17:00:01

It should not be a difficult job to make a replacement. If in doubt about the thread form, use the leadscrew as a template for grinding your threading tool. The flat at the end of the tool should be a little narrower than the flat at the root of the screw thread. That allows a little clearance at the root of the thread,

Several years ago on my first day in the machine shop the compound leadscrew stripped out of the nut. I had to find a piece of bronze big enough to make the nut then machine a new nut.
