ok, so I completely fell off the wagon with the pictures, we have a lot of progress. I'll try to get some pictures tonight and see if i can post tomorrow.

here is the over view of where we are at.

here is the motor mounted. Pullies are in place. You can see the lifting worm gears and cables. Right now i have to turn both together, later will add gears and chain to just be able to turn one.

here you can see the bar mounts and drive flange. I have about 3" of travel in the bar to tighten the chain.

Here is the working end.

I am working on mocking up the oiler.

have the hole drilled and the bolt drilled. will install once i get the oil tank mounted and plumbed.

don't look too close to the welds, but open to thoughts.

I noticed in the 4th picture that it looks like you welded the pillow block bearing to the mounting plate. IMHO I'm not sure that's a real good idea. First off I'd be concerned the welds would crack at the cast block and secondly it's gonna be a bear to change them out if ever need be.
Just an observation I made. I really like the electric motor drive. You got me thinking now. I wouldn't mind have a carriage that I could set on my mill frame for cutting wide slabs. Anyhow, keep up the good work. Looking forward to more pics of your progress.

Were you able to find an electric motor with thrust bearings for a vertical mount or did you retrofit a horizontal motor with thrust bearings? If it does not have thrust bearings do you foresee any issues mounting it vertically.

Years ago we fabbed up a farmers version of a 5kw windmill mounting the generator vertically at the base of the tower and quickly found out why thrust bearings are necessary when mounting rotors vertically, it took out the roller bearings in less than 200 hours. But the fact that it was a WWII era gen set component could have been a factor as well. We were able to find axial contact ball bearings from SKF to replace them and they performed well. The drip guards were reworked as they were useless when mounted vertically.

Good looking build, keeps posted on your progress.

Looking great!

How many hp is the motor?

Where will the oil drip on the bar?

On my setup I wanted to use the original bar oiling hole, but gravity fed oiler just did not deliver enough oil, even after drilling the hole to significant size it still did not work.

I changed it around to oil the chain right where it enters the bar rail before the cut, works well like that. I cut away from the saw head, unlike chainsaw.

thanks guys, as far as horizantal or veritcal. The motor i got stated that it could be mounted either way. So i am assuming that I'm good either way. never really thought about it, but i do not forsee any issue.

The motor is a 10 hp. bigest one i could find in a single phase. looking back it would have been much easier to just get a 10-15 hp 3 phase and use a VFD. Cheaper and less head ache.

I agree on welding the pollow block bearing housing. but because of the size and with good maintenance i hope to not have to change them very often. I just got into welding everything and got a little carried away.

The hole that i Drilled is on the roller end of the bar, so that is where the oil will feed in. just like the Alaskan mill axullery oilers are. So the oil will come into the bar just before it rounds the nose and enters the cut, or just before it enters the cut. depending on if i flip the bar for wear.

Motor starter and wire on in route, will be ordering chain soon, and then just need a few weekends to get it all set up. maybe Feb or March.

Just for safety I would drill some holes and put bolts
in the pillar blocks. I don't think your welds going to
hold. Did you use ni-cad rods ? Welding cast to steel
will 90% of the time snap right off.

ok, thanks. I had thought of do that just had not got around to it.
