Re: D1-3 lathe chuck

If it is a D1-3, you can get a backing plate for a lot less than $500. You can pickup a nice Bison from KBC for about $250. Or pick up a cheap generic D1-3 plate from Shars for as little as $65 (depending on size/finish). See also: Grizzly, AllIndustrial ($40 ???), AjaxToolSupply.

Re: Does Anyone recognize this follower rest.

The Logan (and apparently Southbend?) used a 4-digit part number on the older lathes. So, for instance, follower for an old 14" Logan was part# 6320, a steady rest was #6315, etc.(I think they became AC-xxx part numbers sometime very early or pre-1940). Unfortunately I just haven't been able to find...

Re: Does Anyone recognize this follower rest.

I searched for a while but haven't yet found it. Based on the style (orientation of mounting lugs, sweeping frame) I think it is a Southbend or Logan, probably pre-1940. I found lots of very similar followers, but most (like above) have the dogs on the opposite of the frame. So far my google-foo has...

My Google-Foo says post#17. No idea if it has wiring diagrams in it or not.

Re: trepanning, or how to bore a 4" hole on a lathe without boring a 4" hole

Wilks does lots of special alloys as well as standard steel. Trepanning is done for a whole array of different reasons, including: - special alloys that are not produced as cored product from the mill - sizes that are not readily available from the mill (particularly for one-offs, no mill is going t...

Re: Uneven cut

Are you climb milling or conventional milling? Also, are you maintaining a constant traverse speed or stopping/starting? Looks like climb milling with a stop/start and a bit of backlash in the X.

Re: Wanted - threaded steel balls, 5/8-11

You might try a local wrought iron fencing/railing company. I know IMS has solid steel balls in their fencing selection that you could drill/tap to thread on.

Re: Diacro Model 24 (24" x 16ga steel) finger brake - making fingers

My HF grade 52"x16ga finger brake appears to just uses 3/4" thick (as I recall) fingers that appear to be a plain cold rolled steel (probably 1018 or similar). The fingers are not hardened.

Re: Parting tool used by Stefan Gottswinter

It's similar to a Tool-Flo grooving/parting insert and Walter makes a Cut MX system, a triangular/quadangular insert that fits in an indexing slot toolholder. I wasn't familar with what Stefan's specific system was, I figured it was some small specialty German producer, but searching around a bit I ...

Re: Center Drill Tip Broken Off In Hole

Another thing you can try (if the hole still needs to be enlarged) is to use a small cutter-cutting endmill (or a stubby stout drill with pretty flat face) and drill 3 holes around the perimeter of the broken off carbide tip. Then you can usually use a small punch or screwdriver blade to loosen the ...

Re: Removing End Of Broken Pipe From Pressure Pot Manifold

I agree with warm, I would try first without heating. Also, you can try drilling out the core with slightly larger than the pipe bore sized drills to thin out the thread profile. This will release compression in the stuck piece and make it easier to remove. If you really want to heat and don't want ...

Re: 5C collet chuck

I think you want to search for a "plain back 5c chuck". A bunch of different manufacturers make the; Bison, TMX, etc., also the cheaper China versions. There is also a cheap round cylinder 5c chuck (I have one) that can be held in a standard 3/4 jaw chuck. Examples: https://www.kbctools.com/itemdeta...
