I see you adhered to the old adage " Don't force it, get a bigger hammer"

Thanks Ted. I got the same machine torn down in my garage right now. I have the base and head cleaned primed and painted. The table and other pieces next. The spindle looks good. I cant decide on whether to tear it down or not. i have all the bearings coming in from Ebay tomorrow or the next day. Thanks for the tutorial. I look forward to more vids!

G'day Rusty. Since you have it that far, you might as well go all the way. Long as you tram it all in, you should have a good run with it. Have fun & let me know how it all finishes up

I almost bought one of these in 1980 back in UK before I emigrated to OZ as I assumed OZ was a backwater and machinery hadn't been invented etc.......they were affectionately known as Taiwanese Terrors due to the very poor production at the time..

@@TedRoza Having used one at a friend's establishment I can say truly they are not worth the money at half the price but better than nothing if that is all that is available...........just my opinion.

Apart from a bit of backlash in the feed screws - backlash couldn't be 1/8" since the lead screw pitch looks to be about 1/8", the main problem is you were not using sensible milling practices. 1). if possible, always cut in a direction whereby the rotation of the cutter pushes or rotates the work away from the cutter. 2). if not possible to do the above, use the table lock, that's what it's there for. 3). prior to cutting, stop to tink what the consequences o fyour actions will or may be.

Thanks for your comments. I was emphasising the amount of side movement & the noise you could hear & if you look closely you can see the table moving. 90% of the time I do a standard cut with a the swarf or shaving being sent away from the cutting surface & not a climb cut. You have to realise the Mill is over 20 years old, & this is the first time any major work has been done. Hope this satisfy's you, unless you would like to pick on something else

Hello Micco. Thank you for your comments. Be careful if you remove the main virtical tube, when you remove the 4 main bolts there should be alignment shims under there, which is used for tramming adjustments for the Virtical left & right adjustments. I hope my video helps you a bit

Looks like you started a big project here.

G'day Ted. Are you still using that big 6" vice on the mill or have you gone to a smaller one? I'm not sure if a 6" is too big for my RF45 clone.

@TedRoza

G'day Ken. Thanks for your question, I still have the 6" vice on the mill. It is a fraction big for the table, but works really well. I think the 5" is a better fit & allows a bit extra movement. I have also made an extension plate which bolts on the end of the moveable jaw, which sits proud over the top of the moveable flat section which allows about 8" plate size onto the vice for machining or drilling etc

Hi Tina. Thanks for your comments, & quires. Far as I know the Hafco HM-30 is the same Mill except for the on/off switch & name re labelling. The 30 generally designates MT 3 even though I believe both also had an option depends where you were situated came with R8 spindle. Depends where you are situated, you can contact Hare & Forbs Machinary House, which are the Agents, so you should be able to get parts. If not, & you have to change the " Z " spindle barings, you should be able to source the Barings through one of the Barings outlets. Call out if I can be of further help.

Thanks. If you had been local I could have shown you how to do it. Remove the fine spindle & cross shaft, place block of wood or something under the spindle, then in the nose of the spindle there is a wedge slot, place a flat bar through there to lock the spindle, then remove the large belt drive, undo the large nut, then the spindle should come out the bottom. Be careful to check for any shims, which have to go back in the same position. Make sure if changing the spindle Barings, that the same thickness barings go back in. If not place shims to make up the space to the .001" or to the closest part of a mm. When refitting the shaft you have to recheck the virticle movement for backlash to the .001" , which is very important, or chatter will occure on horizontal cuts. You can slightly overcome chatter by loading the downward spindle & locking into position. Hope this helps
