Sooo I am working on another project. But I need to order a couple small parts before that build progresses, and I start the build project.
However in order to order the parts I needed to order (whew) I needed to do a little disassembly..
In order to do that I needed a tool I didn’t have.... (of course)
SOO In good Madmodder form I decided to make the tool instead of buying it for 150 DOLLARS!!! :bugeye:
The tool I need is often listed as a pin wrench, pin spanner, or some derivative of that with a weird proprietary code name. It also carries a hefty price tag depending on where you buy it from. So I was annoyed with that so decided to make TWO of them myself.
The two nuts have 4 radial slots in them, and are tightened against each other. So therefore I need two wrenches. They also need to be (trying to remember the dimension) .2" wide max with a .1 pin IIRC (If I remember correctly)

We begin this task with two cheap Chinese Vice grips from our local ultra cheap closeout junk store Big Lots. 4 bucks each.
Add in two 1/4-20 by 1/2 inch long bolts with square heads, and were on our way.
For starters I needed to drill a hole through the head of the vice grips to thread for facilitating the bolt placement. In order to do that I needed to mill off a flat spot on the head of the vice grips.
However its hardened.. so I needed to anneal it first.. which consisted of heating it with a propane torch till it was putting off a orange flame, and faintly glowing.. then letting it SLOWLY cool back down, by reducing the flame over 2 minutes till it was off.
Once cool I was able to mill a flat spot on the head of each wrench.
Pre- annealing

After the annealing and flat being cut, I was able to spot drill it with zero issues.
(http://img98.imageshack.us/img98/5934/1031529.jpg)
From here I was able to easily drill right through it, and then run my 1/4 -20 tap right on through.

(http://img43.imageshack.us/img43/6140/1031535.jpg)
At this point.. I needed to mill down the heads of the bolts, as they were too thick, and too tall… so I needed to take them in the mill and make them smaller.
SO thinking like a mechanic.. not a mechinist.. I put them in double nuits, got them Ultra tight, and chucked them in the vice so I could just machine em on down with the carbide single sided mill I have.
Now looking at that picture below.. do you see any issues with that concept?? Potential failure points???
(http://img854.imageshack.us/img854/1426/1031537.jpg)
After standing there scratching my head listing to that voice screaming at me in my head.. I was thinking… what a minute… if the mill comes in contact with that… it will impart a rotational force… and the bolt will TURN.. and then its clearances will suddenly change radically.. causing the ¾ inch indexed carbide bitted mill to likely explode all over me.
Using my brain for a second.. I decided that was stupid.. and thought like a mechanic for a few instead.

(http://img171.imageshack.us/img171/889/1031543.jpg)
From that point… feeling refreshed from almost being a dumbass. I moved to milling the teeth out of the vice grips, and making them the proper radius for the nuts I needed removed.
Enter the 3” boring head!
Initial setup I decided to change….

The final setup post machining.

The wrenches.
Welded the top of them.
Ground them down on both sides taking the shoulder off of the jaw opening.
Heating and quenching them to re-harden them.

(http://img847.imageshack.us/img847/7711/1031548.jpg)
Clipped onto the rear nut nicely.

Double jaw…

So now to remove that little pin that sticks up.. and take measurements for the thrust bearings on each side….. and begin posting another thread for that main project.

What sort of frogs ????

BTW I think they are what I call a 'C' spanner ...
Good thinking though, always seem to de-skin my knuckles with C -spanners ...

What sort of frogs ????
Yellow 'uns ...... just like Arnolds lathe :lol: :lol: :lol:

I had to make three sets of C spanners for my lathe. The easy option is to cut them out uf a strip of BMS with a hack saw and a file.
I suppose you could be really flash and use guage plate if you want to harden them.
Quick and dirty. Worked for me.
Dave.
p.s.
HS93,
Re things Mozilla. Thunderbird is an Email client, not a web browser. You need Firefox for that.

Heya all!
Um sorry your PC isnt showing the Pics.. not sure on that.. it is likely a configuration issue with the PC itself. I would delve into troubleshooting it but that would require a different thread/forum to cover the pitfalls of IE/Chrome/Firefox and making the three of them play happy on a PC, or not..
The spanners were about 5 minutes from being cut with the plazma torch from a plate of 1/4 inch steel. But the thing is damn heavy at 3' by 4' and I was being lazy as it was something like 436 degrees outside.. so the thought of standing outside in the sun and using the torch to make a plate of steel hotter wasnt appealing. Then there was all the hand filing and grinding.
SO yeah..
As my friend Mike says.. Smashing Gnats with a sledge hammer. :hammer:

Well that is strange, I have no idea then - It does say "To view register at ........."
So do I have to register to see them?
DaveH
-
you shouldnt. They are hosted at imageshack.us
But everything I have posted here and all the other forums I have ever participated in have been hosted there. SO no idea why you cant see them. I even had a co-worker check on firefox, chrome and IE.
-
Scott,
I'm using Firefox at the moment, I did try with IE8 still got the same, so it must be my computer blocking it.
I'll see what I can do.
Thanks for your help.

DaveH,
If I may chip in, me thinks your PC has got a bug (virus). :( That regestering to view sound very suspicious.

Abraham.
I might have, who knows.
I have anti virus thingy and an iternet security programme called Bit defender, normally informs me if something is wrong.
But there again my computer knowledge is miniscule.
Maybe somewhere I need to turn something on or off :D

Thats very cool, adjustable size 'C' spanners. :beer:
These are the ones I made for my lathe spindle lock nuts.

I'm a little confused.... :scratch:
Why would these http://shop.ebay.co.uk/i.html?_nkw=c+spanner be $150 in the USA?
They are only £10 ish!
Still, I bet you had fun making the tooling? :dremel:
Oh and just to be part of the alternate use of this thread..... Pic' issues..... Not here :)

::) I also get the yellow frogs like Dave...
:lol: does remind me of the new lathe :lol: :lol: :lol:
Apparently Imageshack checks your IP address to view the picture, and if it's not from a domain that is registered with them, one can't see the pictures...
Looks like Southern Africa's ISPs are not registered with them.
Only way is to create an account with ImageShack so you can log in then.
No way I'm going to register domains with them; I have Internet access through three different ISPs as well as my corporate one....
Might be tempted to create a login at Imageshack in future, but not yet though.
So for now, yellow frogs it will be then :doh:

Don't know if it would work but have you tried logging onto MM through a proxy server that hides your IP address, this might allow you to view the pics ??

Heya All,
Yeah So like... the issue I ran into.. I had a feeling using those flat metal bicycle spanners would bend as the nuts were a bit tighter than I was wanting.. and actualyl they were painfully tight against each other. Took the use of my knee, and both hands at 80-90 percent to get them to un-bind with each other.
30 bucks for the adjustable ones from WT Tool. http://www.wttool.com/index/page/category/category_id/16052/
Grainger has them from 47 on up.
Its realllllly annoying how nice the options are for you lot in the motherland.
An example.. I had to buy oldham joints from Arc Eurotrade after spending several days searching all the US locations trying to find options for having two different sized oldham couplings that have the same diameter. Ended up spending wayyy too much money on them after shipping, and the surprise taxes via Fed Ex. The 3 dollar joints were orders of magnitude more than I would have imagined.
THe c-spanners (didnt know that was the name) were fun to make.. and a good way for me to get back int he garage and make another set of tools :)
Now I am researching thrust bearings.. and found a vendor from someones link that is here in the colonies, and very very affordable.

I know it's a bit late but the "C" spanner intended for ER collets might have been worth looking at. They seem to be forged from steel and only cost £4 each from Arc Euro. For that price it would be worth buying two and grind/mill them down to the thickness you require. If any one is interested http://www.arceurotrade.co.uk/Catalogue/Collets/ER-Lathe-Collet-Chucks they sell two sizes one from 32-42mm and 45-52.
Ned

Good to know Arc Euro has em.
I am going to have to start a list of things to buy from them... and then get a slew of things all at once.
Since it is shipping across the pond it gets VERY expensive. I get a plethora of fees and taxes added on sadly.
The Division Master and motor that I ordered was excellent price and value, but shippiing and taxes caused its end price to be a lot higher than anticipated. (SWMBO thankfully missed that part of things)
Oh and the other thing.. the ER collet wrenches are all good.. but we are talking a 25MM nut.
Scott
-
Hi Scott,
I think even the description "racing tolerances" would not cover the differences. Oh well, at least I tried to help.
Most of Arc Euro's stuff comes from China, so it should be available just as easily on your side of the Pond as it is here, whether your dealers are as "user friendly" as Arc, I could not comment on.
Ned
-
using this idea will be pretty useful for reclaiming some worn "c" spanners in the shed, thanks!
-
I think where Scott's idea comes to the fore is in two aspects.
The first is that it is adjustable for different sizes, and the second, and more important to me anyway, they are locked on, so no more grazed knuckles when a normal one slips off a really tight nut.
When I get a little time to myself, I will get me a pair made.
Nice one, or should I say pair.
John
