Is it my turn? Anything to do with lathes, mills and other shop tools

Not always about tryin' to save a buck, sometimes it's fun to make things just to see if I can.

Intermediate pulley, figure 2 short belts will be better than one long belt. Looking at about 40+ inches center to center. Hoping splitting the distance with shorter belts will cut down on excess slack & "whip".
 
You guys know; I know nothing, But in some YouTube machining video comments; guy says I just decide I gotta do a project and learn as I go.. so dove in.

This was the scary part, two pieces clamped together by and angled in the 4 jaw. The hole needed to be 1 1/8", But it went well never moved a bit.

I paid for lack of accuracy centering the hole exactly on the seam, but was able to machine out the difference later.

The milled "cap" flipped upside down was my first handlebar extension riser but I needed more height.

This locates it on the existing riser cast in the top triple.

To round off the front and back I just grabbed a big file and made chips n sweat.

It helps the old man a bunch!

Pegs down 1 1/2", bars up 1 1/2", seat "repadded" plus my sheepskin. It's been gggGaryized.
Amazingly close to Madness position now.

A while back I made a little screwdriver for the mixture screw on my '81 SH which I no longer own. Unfortunately I could not find it today but below is a very similar copy of one I made for my Virago:

The screwdriver is made from some 12mm bar and the tip was carefully filed to match the mixture screw. Because it is short and heavy it can be dropped into position on the XS carbs with the engine running while you rev the bike up and adjust the mixture screw without it falling out. I center punched markings at 90 Degree intervals so it is easy to work in increments of 1/4 and 1/8 of a turn.

Hi Paul,
nice gadjet! If I was to pirate the idea I'd use hexagonal instead of round bar.
And who's the bird, eh?
 
Making those risers above I was seriously unimpressed with the surface I was making It was just a used highspeed end mill. So I started looking at indexable carbide end mills that's a worm hole in itself. Anywho I started thinking I better see how true the spindle is running before trying to decide "how good,$$" the tooling needs to be.

Crap. Sat and thought about it for a few days.
You can see in the video the wobble isn't directly related to revolutions, so after reading a bunch of how to rebuild a spindle posts, I found that is a sign there's prolly issues in the bearings rather than a bent spindle The bad news is spindle bearings are really pricey. So I tore in today.
Things went pretty well.

The Hoyer lift was handy

One time use tools, a pin wrench. Took a while to beat that big collar loose of it's threaded hole.

Grease was nasty.
Lot of cleaning later and the bearing seemed good. Some one had been in it once, long ago, they left marks. carefully stoned and removed any ridges etc.

put it back together with light grease. Was hoping for a bit less runout, but not a new machine.

Whoop. whoop! that's a .0005" indicator....
I also worked on the R8 taper and upper bore with round stones and fine paper, cleaned up some old boo boos.
Just cheap chinese collets but...
Have a little project so brought in the rotary table, will figure out set up and drill a bolt circle in an aluminum disk.
Now I gotta decide on some tooling. Would like to make some more risers.

I've had good luck with the HTC 3fl carbide stuff for aluminum. Price isn't bad, about $20 for a 1/2", and with a little WD40 they last really well in aluminum.

Nice job cleaning things up. I should probably do that to my mill sometime.
 
AFAIK nearly all the "old" lathes run in babbit. there's how too's on casting new bearings. if the spindle is not sloppy then it's possible to grind the jaws on a 3 jaw chuck to get it back into true. This stuff is all deep worm holes, takes some study time to find out the real issues, and "home shop fixes" that can be attempted. I finally gave up on the ancient Southbend lathe I inherited from dad. The ways were just too worn out to allow any decent work. Regrinding the ways is one of those beyond reasonable cost things.

Just because it's raining and I'm bored, I took the chuck off and popped the bearing cap off the chuck end of the spindle. Looks really good in there and I can't move the spindle around by grabbing the chuck and wiggling.

I've thought about replacing the chuck, but buying another 100 year old chuck and hoping it's better is a crap shoot at best. The spindle nose is a somewhat odd size and thread (1-7/16 x 12), but I may be able to find a new chuck or adapter that will work. But again, that's 3-400 dollars I don't want to spend right now.
 
Did a little surfing. Chucks are out there at reasonable prices, the fly in the ointment is the mounting plate. I'm fairly confident that I could make the basic plate, but it needs an internal 1-7/16 by 12 thread. Well beyond my capabilities.

Ah, but there are many who can turn that thread for you , and more than a couple happy to do it for small compense 'cuz they like to do machine projects.
