I spent $300 on my conversion. $150 for spindle used from Ebay. $125 on new bearings with new lock washer and nut. Plus a few hours on the lathe turning the spindle down and grinding new splines. Approximately $25 on inserts and grinding rocks. I found a piece of 4140 tubing to make the spacers out of. Modified the original bearing adjuster to fit the new spindle.
I had a draw bar.
Its pretty much a full day of work to make it fit but well worth the time involved!

This would be of great interest to me as I have an M head to assemble and have always thought there wasn't room for an R8 opening.

Thanks much!
True Tom but I have the great advantage of cheap plentiful tooling and a really light M head. The light head is so easy to adjust. I can swap the belt around to do just about anything I need to do. I rarely drill holes over 1". I use my fly cutter to bore out cylinders up to 5" diameter. I'm not trying to make a living running a business with this thing. Its for projects. I can make just about anything with this machine. It makes you a better machinist using a low hp machine. Anyone that has enough money to buy a big mill that has plenty of hp. And a VFD, rotary converter, 220/440 or 3 phase at someones disposal makes it even easier for them. Every situation is different. If I had $4000 to blow on electrical wiring I would run 220 to my shop and buy a vfd to run a larger mill, plus I would have to buy another mill that works as good as mine. Yes there is plenty of affordable mills out there but The logistics of it is a pain. This mill is great for what I wanna do. If I wanted to do big stuff I would just take my project to a local machine shop. There's no way to justify me buying a larger mill. Maybe a longer table but If I'm working on things that require drilling large holes or heavy machining on a regular basis then I would just need to open up a machine shop for profit.
