    Shaper oiling solutions

    Several years ago I also picked up a shaper without oil pump - Varnamo No3. Somebody packed it with grease and removed oil pump, hoping to solve all lub problems once and forever. What i did is similar to yours - I found gear based hydraulic pump, mount it with small induction motor on the...

    Becker No 3 vertical mill - "restoration"

    Here is a second reiteration on motor mount - motor is running and spindle is rotating - mill is actually milling :) . Two issues that I found that need to be addressed: 1. Moving motor up and down is a real pain. Very inconvenient and clumsy. having something in mind - see below. 2. Pulley...

    Becker No 3 vertical mill - "restoration"

    Slow but steady progress. I casted and machined alum pulley. Used an existing flywheel from treadmill - made a sliding fit with two bolts holding it firmly from the back.

    Becker No 3 vertical mill - "restoration"

    Drive fitting is delayed a bit and, meanwhile, I put knee, cross-slide and table on. I was was searching for oiling channels in the table ways and I finally discovered it after cleaning all rust, grime and yuck. It is in quite unusual place - right inside T-slot. You can see "OIL" stamped in...

    Becker No 3 vertical mill - "restoration"

    Ken, may be you remember how gibs on knee and on X slide were adjusted. Mine has just three bolts each that pulling gib to the body with no any counter nuts or jamming nuts (or any other) to keep it evenly pressed to the dovetail. So I can just tighten those bolts until knee or X is completely...

    Not too much progress over weekend - black and red currant berries are ready and we picked it up and spent a lot of time processing it :) . Still a lot to go , though Was abbe to determined and made wooden pulleys for the motor, keeping in mind that belt need to clear bracket of the spindle...

    I am making pulley from plywood to see if its diameter enough to get it around. Will mount it tomorrow and post picture. Regarding handweel - would be lovely to have one if shipping cost is not prohibitive.

    Second variant for the drive - straight from the motor to the pulley with single belt transmission. Indeed, looks cleaner and simpler. Motor can move up and down to align with spindle step pulleys and the entire assembly - back and forth for tension adjustment. Need to estimate motor mount...

    Becker No 3 vertical mill - "restoration"

    Right. I wanted slightly more - 1000-1200 RPM. I will follow your suggestion and will mount motor directly to drive spindle pulley (no intermediate driveshaft). DC motors usually have falling load/RPM characteristics - how was your motor keeping up with speed under the load?

    Becker No 3 vertical mill - "restoration"

    Here is what I thinking about drive. (sorry for the clattered background ) DC motor on top with poly-V belt and two pulleys will be driving countershaft and step pulleys, I will be able to regulate speed - to some extend - with DC motor supplied voltage and if I need other range of speeds -...

    Well, it creates an issue with belt length - I have to have long belt adjustment leeway to compensate it, right ?

    Becker No 3 vertical mill - "restoration"

    I started to think about drive and transmission - original assembly looks and works terribly . It is heavy, slow and noisy. To be honest -original parts are also somebody's improvisation, so I am not feeling like ruining something. Moreover, I am keeping all original parts and pieces of...

    Frame, knee and knee rising mechanism are installed. Wooden braces that yo see in the background - to strengthen seiling as I am rising and lowering heavy parts of the mill.

    It is definitely a help - thanks. My mill seems to be newer - there are screws on each axes.

    Becker No 3 vertical mill - "restoration"

    Excellent write-up. Thanks. I did not cleaned (yet) spindle from inside , I just unscrewed zerks and looked inside - indeed it filled up with heavy grease. Need to search for suitable pressurized oil gun or may be I can retrofit one of my grease guns.

    Becker No 3 vertical mill - "restoration"

    Thanks for your suggestions, folks. I am using all spectrum of tools I have and also I already borrowed needle scaler. I cleaned most of the old compound, not 100%, though. On frame I already used two parts epoxy primer - it has cured quite fast and stuck to the surface quite nicely (for...

    Becker No 3 vertical mill - "restoration"

    Thanks for the suggestions, folks. I took a sample of that black putty and went to the local biolab. They made express test for the led and did not found any ,so I am safe :) . Digging into internet I found some discussions and videos where people suggested this is corn starch with linseed oil...

    Becker No 3 vertical mill - "restoration"

    Thanks for the info, Joe. I was thinking about smoothing out surface with this old filler. It is not getting out easily so I am leaning toward to just leave it in the deep spots. The only concern is - will primer or Bondo stick to it?

    Becker No 3 vertical mill - "restoration"

    Working ion cleaning again - table, saddle, reverse mechanism for power feed. Asking for common wisdom opinion - all castings are covered with older style putty which is very "oily" . This black putty was made before synthetic Bondo invented. Is there any simple way to remove this black...

    It just happened this weekend - I scored granite surface plate on local auction for reasonable price. Though I promised :) not to scrape - I went ahead, took gib/side for the vertical movement of the spindle and started practicing.
