This is a bit of a continuation from this thread:
Getting a Monarch Series 61 Back in Service
My original plan was to clean, lube, and align with minor repairs. I decided a while back to take it few steps further.
Please note: my goal is improved, not perfection. My goals are improved contact for rigidity, improved bearing surfaces, and improved accuracy.
Keep in mind that I'm "working with what I got". That includes skill set and tooling
. In general my goals are to improve inaccuracies and contact surfaces by 50%. If I manage to get everything even tighter, let's say the .001”-.002” range even better.
I don't know the outcome yet, but reaching any, or both goals would be a victory to me. I would not expect pretty or photogenic scraping patterns
. I'll do my best, but my goals are more practical, functionally more rigid, better bearing surfaces, and improved accuracy.
My plan, though I expect it to change as I cross each new bridge:
1a: Make a new bearing in qcgb for feed screw. Might also attend to end bearing block for lead screw, feed screw etc. Prefer to do later, but I want rods sitting right for survey.
1. Survey. I want to do a survey as complete as possible before making changes.
2. Pull tail stock upper half. Get lower half scraped flat. Lower half will be used as a trolly. I will begin to build part of that trolly and continue survey.
3. Pull head stock. Continue survey. Determine if trolly is stable and accurate enough to carriage ways.
4. Build upon the trolly to hold a grinder.
5. Grind the carriage ways. Maybe only inner vee for carriage. Maybe all, unknown yet.
6. Build up and scrape in carriage using c932 bronze. Using apron, plus lead screw, feed rod etc to help determine the numbers.
7. Install and align head stock to bed ways.
8. Align cross slide/compound to head stock. Whether that happens through cross slide or compound adjustment, not sure yet.
9. Adjust tail stock height and alignment.
Then I'll be sorting out the rest. No doubt I'll have some side steps along the way, or jump around a bit. But this is the rough idea.
Current state of affairs, plus data tag and build sheet on machine:
