OK Chaps this is not going to be pretty so any one of a nervous nature look away.
When I did the key way slot in the pulley for my sub spindle I could tell I wasn't doing my machine any good I was putting a lot of load on, and as I've decided to remake the pulley, I'm not too happy with the fit, I realy need another way of cutting the Key Way. As I'm also suffering from project creep like Bernd, this is going to be a no frills job it'll look ugly but all I want, is for it to do the Job :hammer:.
OK gather the material together and put a rough plan together

Bits of garage door Thanks Ralph :thumbup: (where is Ralph :scratch:) and 20mm and 30 mm bar and a off cut from a shaper job some one was doing that I piced up at the scrappy.
First job drill some holes in the channel for M8 cap screws, this is going to be the base.
(http://i431.photobucket.com/albums/qq32/sbwhart/Key%20way%20slotter/100_2461.jpg)
Those garage door bits make great clamps Ralph got any more :D
Bolt the bit thats to be the ram guide to the base with M8 cap screws. sorry no pics of drilling the guide.

Drill and tap M8 a chunk of 30mm bar for the pivot.

The ram guide needs to drilled on centre: easyest way set it up square on the the saddle, bolt it up, and get it positioned and lock up the cross slide.

Centre drill it
(http://i431.photobucket.com/albums/qq32/sbwhart/Key%20way%20slotter/100_2466.jpg)
Then drill it with 8mm pilot then 13mm pilot and finish of with a 20mm drill
The channel was springing back so rigged up a jack to stop it. I may add some corner bracing.
(http://i431.photobucket.com/albums/qq32/sbwhart/Key%20way%20slotter/100_2467.jpg)
Putting the 20mm drill through. I stopped the lathe and removed the swarf using a pair of pliers, it was as sharp as a razor, handling swarf is the only job I wear gloves for.

Hole drilled.

Should get it finished tomorrow thats if the boss leaves me alone, herd her mumbling about going to the Traford Centre (Moll) :(
Have fun

I cut a keyway on the lathe once and agree it does give one a feeling that they should be shot..... :lol:

Ok home run
Maching the ram to size between centres
(http://i431.photobucket.com/albums/qq32/sbwhart/Key%20way%20slotter/100_2472.jpg)
Putting an 8mm slot in the end of the ram.
(http://i431.photobucket.com/albums/qq32/sbwhart/Key%20way%20slotter/100_2473.jpg)
This end was also tapped M8 and one arm open up with a M8 clearance drill to take the pivot pin.
The other end was drilled down the middle 10mm and a M5 cross hole tapped to grip the tool.
The back link:- again this was slotted 8mm and cross drilled and tapped M8 to take the pivot pin, a flat was put on the other end with another 8mm pivot pin hole. Made this bit complete then parted it off.
(http://i431.photobucket.com/albums/qq32/sbwhart/Key%20way%20slotter/100_2474.jpg)
Made a tool holderthis was just a length of bar with a 6mm cross hole, with a M5 clamp screwe down the middle.
This is the tool on the lathe.
Forward

Back

You can see the swarf shaved off

No-one else has mentioned it, but the wine cork in the tailstock spindle is brilliant! Beats the bit of rag I have keeping the chips out of mine. :clap: :nrocks:

hello
built a smaller version of this one and it has many uses i found out!

from sbwhart: "The problem is I keep losing it and have to open another bottle."
Hm. What might the problem be in that? Too tight corks? :)

:lol: I only just found this thread :doh:
Yep those are good clamping bits Stew... I haven't gotten any for a while now though.
Good to see someone finally found a use for those big black arm brackets though.... I do have a couple of those around still!
And to those who thought I was AWOL.... I was just resting.... Oh, and spending time re-building the car ::)
Very nice piece of kit BTW Stew :clap: :thumbup:
Ralph.
