Emco Compact 8 dimension request

[Steve-F]

Forgot to ask, what type of file format. parasolid (.XT) or .IGS....just got slammed at work so give me a bit to get it together

I was checking the thread for progress. I'm living vicariously as my wife is "encouraging" progress on spring cleanup and kitchen rehab plans.

Here's another pic of the idler arm and associated parts, though I included it earlier.

Note that there is a little oiler at the end of the idler pulley shaft near the spring clip slot. Grizzly sells the oilers for their 9x, but they're bigger than the original Emco style.

The washer at the end of the spring fits into the slot to keep tension on the idler arm. The washer is about 1.453 inch OD, 1.037 ID, 0.045 thick.
The spring is pretty heavy. The wire itself is just over 0.10 inch diameter, coiled to about a 0.60" diameter, and about 6 inches long.

Thank you Tom!! Much appreciated! I have the motor now mounted and the lathe bed blocked up 1.75" to get some more room and a better working height. Pics, later....took 1 day off and my wife got her first covid shot. The motor pulley and belt drive are done and mounted too. The idler pulley is cut but not the cogged tooth yet, as my machine is married to another job for a while:<(


Thanks!!!

I have access to Solidworks and Autocad. If what you did was in either of those native files are great, otherwise parasolid are probably good. Really anything is appreciated.

Thank you!

Sure:<) I have Unigraphics NX10 , parasolids it is

I thought this might be of interest to you, a Compact 8 in "good condition" for $450 in Kingman, AZ.

Based on the photos I don't know about it being good condition, but looks fairly complete and probably at least good for parts. Thought might solve some of your parts issues. If it is better than the photos make it look then even better. Bit of a drive but might be worthwhile.

Not my ad, just ran across it browsing CL and remembered seeing this thread.

Latest up-date......while I'm still working on the idler pulley, (more on that later ) I had some time to make a QDTP and 8 tool holders. 4 of them for cutting tools, 2 for a boring bar and/or a chuck, 1 part-off tool and still working on the knurl tool. Credit to Neil Wyatt for his handy notes he made available!

So far I have finally mounted the idler pulley and went with a 6" dia. with a J-section, 8 ribbed X .75" serpentine belt with an adjuster in the rear for tension rather than fight the motor mounts every time I want to tighten it. It's a long story coming from the first plan of a toothed drive, it just wasn't panning out, so went with this arrangement On the plus side I should hit the low 90's in RPM's with the 6" pulley
