What is the best way to drill or bore an accurately sized hole in a bar or chrome-moly?

I keep burning up bits, sticking them in the bar stock and have very bad galling. I use good flood coolant and don't let things get "hot". What else can I try??? ]]> Gunsmithing http://www.practicalmachinist.com/vb/gunsmithing/drilling-boring-holes-266178/ Bought an old Hardinge lathe with tons of tooling, need to identify some stuff http://www.practicalmachinist.com/vb/bridgeport-hardinge-mills-lathes/bought-old-hardinge-lathe-tons-tooling-need-identify-some-stuff-266177/ Tue, 21 May 2013 22:43:16 GMT Bought this old lathe with tons of tooling some of which I have no idea what it’s for, if it's complete and its value. I was hoping someone can help me out sorting thru it.

Full picture of the lathe, you can zoom into it:

http://i43.tinypic.com/54ghs3.jpg

1) Serial number is 59-19843-1 (9” swing), can some please tell me what year it was made?

2) What is the proper model name of this lathe? There is tons of confusion with DSM, TL, Split Bed, Model B….

4) What is the proper name of the spindle, it’s tapered, but not sure if it’s the popular 4 angle one, or if there are many different ones like the D type style? Here is a picture:

http://i41.tinypic.com/34fy6uw.jpg

5) The dovetail width is 2 ½” top and 3” bottom; will it fit Cataract stuff or vise versa?

6) The back guard is missing:

http://i41.tinypic.com/9iejif.jpg

How critical is it for additional support to the spindle, since the bearings are in front and mid section?

7) Can I make one from a piece of wood or Acrylic? If so. What type of thread screws I need (3 of them)

8) I was told it had new sealed bearings installed not long go, so if they are sealed does that mean I don’t ever need to take them out and grease or lube them? There is an Allen type set screw on top of the right side of the headstock, not sure what it’s for, any ideas?

http://i43.tinypic.com/e6u336.jpg

9) The spindle has two V belt pulleys at the back, I can squeeze in the belt with no problems, but I’m wondering why there are two identical size pulleys? Does that mean I ended to use two belts at once to drive it? Here is a picture:

http://i40.tinypic.com/24g21ci.jpg

There are tons of 5/8” turret attachments that came with it, some I was able to identify some I have no clue. I would like to get a three part answer to each one

A) What is the proper name of the tool
B) What is it used for?
C) What is its value?

So I can determain if it will be useful for home hobby stuff or better off at reselling and buying something else. Let’s start:



10) Some type of wooden guard or cover

http://i42.tinypic.com/28knfo3.jpg

http://i42.tinypic.com/50p7pc.jpg

11) Second 5C draw bar, it’s shorter by about 5/8” compared to the larger eon that works well, any idea where it came from and what type of lathe it fits. Here is a picture of the two Maybe SB since I have few SB collets:

http://i41.tinypic.com/aonaqv.jpg

12) Picture of the back , maybe after they changed the bearing there were different size parts used , can anyone tell if everything is correct:

http://i40.tinypic.com/2vcjdwg.jpg

13) Some type of knee tool

http://i42.tinypic.com/5ap5yv.jpg

14) Three Brown & Sharpie some type of boring tools 00K, 00CA

http://i43.tinypic.com/dqomr5.jpg

http://i41.tinypic.com/9ri1w8.jpg

15) And larger one says Brown Sharpe Special Friction Tubes

http://i43.tinypic.com/9ib5ts.jpg

16) Some type of tool holder with an angled cut bit:

http://i40.tinypic.com/140aqkx.jpg

http://i44.tinypic.com/e9gmmf.jpg

17) TL 35-8, I have no clue:

18) Brown and Sharpe No 00BA

http://i41.tinypic.com/bf2bdg.jpg

19) Brown and Sharpe 51-200-1 or 515-200-1 the 5 is printed lower

http://i42.tinypic.com/xnsu42.jpg

http://i44.tinypic.com/1409bhl.jpg

20) Unknown – no marking, the two halves interconnect and mover in radial direction:

http://i41.tinypic.com/2itl9is.jpg

http://i43.tinypic.com/116uz5s.jpg

21) Alco Tool Jasaw = 1/32 – 1/8
B= 1/8” – ¼”
The on eon the right has spring recoil in it well it snaps back and forth:

http://i43.tinypic.com/wrbea.jpg

22) Keyway Cutter – it has a range of swing about 5/8” so it will cut on stock up to about 1.25” radius. No markings, not sure if it’s home made or not looks very professionally made, what is it’s value and is it still useful or are there much newer and easier tools availed to cut keyways.

http://i42.tinypic.com/2usv60m.jpg

23) Some type of tool holder 2568, the back 5/8” shank is threaded internally:

http://i42.tinypic.com/dexmky.jpg

http://i42.tinypic.com/3089jed.jpg

24) Unknown says 1070:

http://i41.tinypic.com/2ura3vm.jpg

http://i43.tinypic.com/350rng5.jpg

25) Some type of blade, not sure it’s for this lathe at all:

http://i42.tinypic.com/o9ika9.jpg

26) Bunch of stuff with two brackets, not sure if there was ever a power feed attachment for it and if these are some of the parts or non related

Sorry for such a long reply.

Thanks in advance.

Shoots nice, has a 22mag cyl for it as well. dug it out this weekend and had a heck of a time getting dots on the paper. I would like to do something differantly to make this thing aim a little easier...the airplane tail wing they stuck in the front isnt really my thing, as i tend to struggle with irons. What are my choices? I dont have a problem making something myself if someone has a decent idea.

I have two actual engineers that will help me with this but want to find out some details before I put them through their paces, for me.

I have an idea to hang an I-beam from the roof's rafters, by running a connecting member from one side's
rafter, to the other, and then somehow attaching the I-beam beneath it, allowing for a trolley to roll unimpeded.
Basically, I want to put the horizontal member of the letter "A" up, and hang the I-beam from that...

I don't know the proper vernacular or part names for this, so am looking for help here.

What would one connect the I-Beam to the cross beam with?

A little background: My boss has a Coleman brand pressure washer, served him faithfully for 3 years or so and one day during use the pump grenaded. Since the motor still ran great I found a pressure washer pump from a US seller on ebay that would fit the shaft and mounting dimensions on the engine.

About twice a year since I swapped old pump for new pump, the new pump has shredded enough check valves to the point where it barely puts out more pressure than it does when you pull the trigger on the wand with motor off. The seller gets $23 for a "rebuild kit" that includes new check valve assemblies. The pump itself has no markings but appears to be a knockoff of a B&S design and the check valves look pretty much identical to these here: Amazon.com: Briggs & Stratton Pressure Washer Pump Valve Check Kit 190591GS: Patio, Lawn & Garden

The check valves have stainless seats but plastic frames and plastic valves, and it appears as though when they fail, they get pushed thru center of the stainless seat because the plastic can't handle the pressure (and mind you, its not running at 100% of travel on the pressure knob either), and I'm fairly certain that once that happens the chunks of material go down the line and cascade the wreck thru most if not all of the other check valves.

Frankly, I'm sick of this thing burning thru check valves. I'm wondering if anybody sees a problem with creating identical valves to the originals out of stainless, or if there's a less-crappy all-metal version of these same valves that I could drop in so I don't have to tear into this thing every other time I want to get something cleaned with it. ]]> General greenbuggy http://www.practicalmachinist.com/vb/general/semi-ot-pressure-washer-pump-cheap-check-valves-266164/
