Some nice stuff...!
I thought I'd post pics of some of the stuff I've done with my Shoptask. My machine was built in 1997, I think, and has undergone many, many mods.
Some nice stuff...!
Nice looking work! I really like that 5C collet chuck- got any plans or was it just out of your head? I see you painted your machine blue- Digital is painting his red- Now you guys have got me thinking about a new paint job too.
I have some questions about the 5C chuck. It isn't attached to the normal register surface of the spindle, how do you center it when taking it off and on?
I cut a recess in the spindle, I get TIR of less than.0005".
I spent a lot of money and time painting with automotive paint but coolant just eats it up. I'm reconditioning a tool grinder now and painting with Rustoleum thinned with Acetone. I hear this is great for machines; we'll see.
Re Collet Chuck;
I'm not sure I ever drew it, but I'll look. I made it a while back, maybe 5 years and in spite of crashing into it a couple time it runs very true. (The joy of CNC). I have a new lathe with a Camloc and I'll be building a new chuck for it. I'm not sure it will be a 5C though, I'm leaning toward a ER40 collet setup. They are incredibly accurate and there are no gaps in the sizes. Truth is I'll probably build both; I have so many 5C collets now.
I don't have plans of the chuck but here are some other pics. I modified it later, adding radial holes in the body for a Tommy bar. The threads are a bit course on this chuck, and when/if I build another the treads will match the commercial, bolt down, 5C units.
As I was building it I took lots of pics because I thought I might write an article, but I subsequently lost most of them in a hard drive crash.
If any of you are interested I have an article coming up in Digital Machinist this summer, on using the tool table in Mach 3
And in the Nov/Dec issue of Home Shop Machinist a project of mine will be on the cover with the related article inside.
Some of the parts shown on the first post can be seen on my site [/URL]www.gatsbyvise.com
This vise is presently built completely on my Shoptask.
Since I won't be writing the chuck article I should tell you there are only a couplespots to think about.
Rough the body out and finish the part that goes onto the lathe spindle.
Then bore the spindle carefully; you have the chuck body in hand as a gauge. Don't screw it up!
Drill the mounting holes in the chuck body.
Clamp the body on the spindle using threaded rod through the spindle and some plates or washers.
Drill through the body and through the spindle plate for screw threads; you'll need a long bit.
Bolt the body in place and machine the rest of it.
If the spindle to chuck body is a tight fit, all will run dead on!
It has been a long time since I jawed with you. You have the same model machine as me.
On your lathe part, I saw you had a belt going directly to the spindle pulley (can I get the model and ordering info for the belt?). Also, I see you removed the chain drive for the spindle oiler, how are you turning the oiler? Or do you just not use it, (or some other thing?).
The Bar Centering holder that is sticking out of your pully, can you send me the plans on that (or CAD model), that is a GREAT idea!! would love to see how you connected it in.
Your 5C Chuck: You sent me the CAD on that along time ago, it is good to see it in action. I still have not gotten the guts to try it yet.......
Your Y-Axis Bearing jornal ends, they look great (any chance on CADs on those yet??).
Where did you get those ultra-cool tubular screw covers for your X screw??
What paint did you find that works???
Has been a long time; you still in the land of sand?
From the bottom:
Painted my new Tool and cutter grinder with Rustoleum thinned with acetone, but I'm not quite to running stage yet so we'll se how it holds up to coolant. I've since been told that the very best is auto engine paint! Says even MEK won't attack it!
Screw covers are from McMaster, search bellows; not cheap.
The cross axis, X for me, article was published I guess there's no reason not to send plans. I no longer have your email address, that was 3 crashes ago. Contact me Ozzieii@msn.com.
The rear spindle chuck is easy, nothing special, but make a male test thread spud with the same thread. Test it with one of the spindle nuts. Then when you make the internal threads in the chuck you can test with that spud. If not clear let me know directly.
I just thread it on in place of the rear spindle nuts.
My machine never had any chain drive, it used splash from the gears. But all the gears have been removed, runs almost silently. The spindle just runs in a little grease, just like the mill head.
Don't remember where I got the belt but search link V-belt. I'm not sure I recommend it; I don't think it transmits as much power unless streched really tight. I'll sell this machine in about 6 months I think but if I were keeping it I'd switch to a timing belt.
