Re: bearing tolerance
I was hoping I wouldn't have to scrape.. Oh, well, it's off to the store to get some hi-spot blue. I'll start off with a .01 shim and peel it back one at a time to get the clearance I need. I still have some plasti-gage from my motorhead days. Larry On Sunday, September 13, 2020, 01:12:29 PM EDT, glenn brooks <brooks.glenn@...> wrote: Larry, I have the same problem with my Dalton.

bearing tolerance
All I've left to do on my Lot? 4 is tend to the spindle bearings. If I tighten the caps the spindle turns with? a? lot of drag. I was wondering if there is a recommended torque for the caps and if Bert used shims in his original designs. I can find these by trial and error but I thought I'd ask to save a bit of time. Be well Larry |
Re: Step pulley mount
Thanks, Dennis I thought that might be the case.? The back gear brgs are very tight and lack the set screws (one more thing to make) tho the shaft moves as it should. I joke about hammer mechanics, didn't want to become one. It seems the closer I get to finishing the more complicated things get. Murphy is alive and well, living in Massachusetts. Thanks Larry

Re: Step pulley mount
There is no groove on my counter shaft so I guess a washer was used. Back in the days when horizontal mills were common, I would position the milling cutters using spacers of various widths.?? These are easily made without key ways. Larry

Re: Step pulley mount
¿ªÔÆÌåÓýWhen? I said the countershaft turns 400 max that was if you had both original cone or step pulleys that you don¡¯t have. The spindle can be ran up to 1500 or a bit more providing the lubricator chains are still present in the head stock bearings.? Did you check to see if they are there? ? The rings that go in the countershaft bearings were made of wire or wire rings.? You can make some from 3/32 wire formed into a round ring and soldered at the joint.? They just need to rotate freely as the shaft rotates in the bearing blocks. The diameter of the rings needs to be as large as possible but still drop easily down into the slot of the bearing blocks and rest on the shaft but not touch the bottom of the reservoir.? Later when I get home at the end of the month I can check and see what the actual dimensions are for the rings if needed. I don¡¯t seem to have a picture of the bearing lubricator rings but here is a picture of the spindle bearing bead chain that carries lube oil up to the spindle bearing from the reservoir below. ????Dennis?????????? ?

This is a plain bearing? meaning the shaft rides right on the cast iron of the bearing block.? Given the use of he lube ring and oil these things will last for a very long time.?
