You are going to have to be quite agile to wiggle in there to attach the DRO...giggle...

Yes..an eye loaded so that it is not coaxial with the threaded area can bend and /or snap off unless it has a SHOULDER on it to prevent such. do a google search on LIFTING SWIVEL and /or SWIVEL EYE BOLTS and if you have a RIGGING HANDBOOK...the Bible from which I learned rigging in the previous mill...

Spent many years lifting really large loads and was trained that lifting limits are generally a function of the 'eye' or 'lifting ring' and not the hole into which it is screwed....assuming that the hole size / threads were correctly calculated in the first place. Professional riggers generally use ...

I like setting my machinery on adjustable feet so that they can be set and kept level...and cleaned underneath. Some base designs make this difficult. Your crane picture reminds me of a friend who cut a hole in the roof of his house / some floor joists / ceiling drywall and set his mill directly int...

I second the comment about 'DO NOT OIL'

I ordered one from a fellow a while back & it arrived all nicely cleaned and lubed

Crude but effective...

I didn't say that I wasn't going to buy...just seeing if these is an alternate option.

I don't care about the wheel size...for a riding car, it matters not to me...

getting the thread mill in / out is a challenge, especially with an ID thread. If using a single point tool, typically you helical mill down to depth, the make at least one full 360 degree arc move, then move radially until the tool is clear and pull it out of the hole. The same can be applied to an...
