Bob:
Thank you for all the info and your help is greatly appreciated.
Thank you for all your time.

Mike, Duh, guess the picture of the lathe you posted is 'your' lathe. I did not catch it in your avatar. I am going to say the gearbox on the 100 is the same on 4808. I know the output shaft is the same diameter. Main thing you want is getting the lead screw with the apron.

Do you have the gear train cover for your lathe?

Did you get the serial# off your lathe? Curious to see about what year. While cleaning up my lathe I though I saw some OD paint as first layer. I used a needle scaler on my bed and all the paint just flaked off.

Thanks

Bob:
Yes I do have a gear box cover, I had it off for cleaning.
I don't have a drive belt guard. It would be nice to have it.
Thanks

Mike,
I have seen people running lathe without the gear cover - accident waiting to happen. The factory belt guard was extremely rare. Only seen one Clausing 100 with a factory belt guard. I plan to fab a belt guard cover.

Newer 4808 had a motor mount attached to the lathe bed. The motor tucks under the headstock cover and had a belt guard.

If you know any one with a gear train cover, I am interested to purchase.

Wow another month flies by. Been busy installing new railing on the new deck.

Lathe wise, have been working on the Yuriy‘s TouchDRO on the bench. Bought the TouchDRO kit which requires some assembling... Could not find the original iGaging double male USB mini-B cable. Reworking another USB mini-B cable to work. Still not getting the carriage scale working. The crossfeed iGaging scale was plug and play. When both scales are working and mount, they will require calibration using a 1-2-3 block to measure a 3.000” travel.

well0058 What a great thread. I just inherited a Clausing 100. I contacted Tom McNett and mine was purchased 5/02/1945. I want to upgrade to 3 phase with a VFD. I look forward to seeing your progress

Hi Bubba - Welcome. Aboard

Great to have another Clausing 100 owner. Did Tom have info who originally purchased your lathe?
Welcome to post photo of your lathe. Nothing like lathe porn...

After you do your first VFD, it is a simple process to use a 3-phase motor. Biggest thing is knowing the VFD parameter settings. I decided to do VFD on the cheap with a China AT1 inverter. Post# 35 has photo of my parameters and link to a UK site regarding using the AT1 inverter.

Other main brand inverter mfg offer good documentation and support. The next VFD may be my drill press.

Tom did not have who purchased it just when. Mine is S/N: 3985. I will most likely go with a similar vfd I like the ability to jog, also the kbac ones are getting expensive. I bought one a couple years ago for a 2x72 belt grinder I built a couple years ago.

Thank you Bubba posting photo of your lathe.

Well got two hours in this night. One end of carriage scale mount is done. Next mounting scale at the tail stock end and fab a cover for the scale.

Well got a chance to spend this weekend to work on the lathe. Shout out to Mike from Missoula, MT for hooking me up with a gear cover. Got the X axis scale for the carriage travel finally mount and calibrated, test the X axis DRO, test the DRO for any EMI interferes from the VFD (unshielded PCB next to VFD - no problems noted) and installed the new gear cover. Now working on the X-Axis scale cover then can move lathe to final location.
