Mini mill Stand SX2 Plus

(1/3) > >>

Buell:
Heres a few Pics of a Mill stand I have been Making.. Made out Of 100x100 fence post I found at the side of the road ! and some 1/2 " plate I got for cheap as the base. Side cheeks are 10mm i think so pretty beefy.

So my idea was to give some more mass and to try and stop some of the flex in the Head to the base. Also so i could tram the head to the base i put a couple of bolts in the top of the column ...One tapped in and one to push the column away. My thought was to aide in adjustment...works a treat. My only concern is if there is any twist in dovetails on the head.

Its a lot better having tried it today ..just wondering if i should fill it with some dense material.

Brass_Machine:
Looks good. There is a huge thread over at cnczone about using an epoxy/granite mix as fill...

Only concern is if I want to drill and tap any holes in the future ! Masonry bits at the ready!!

Ok so the post man just came Looks like the lead screw i ordered of Flea turned up ....wouldn't mind but it came all the way from the East to have a Man from the west in a Red uniform jam it thru the PostBox ...Lets hope its not bent out of shape !

Anyway my idea was Firstly to make a stronger and longer lead screw with larger diameter hand wheel and a way of fixing on the left end of the bed to a stepper motor to enable powerfeed. I can see this just going down the Cnc route but Not at the moment.

Concerns at the moment are...

1. New Lead-screw is stainless machining it !
2. End float Backlash etc. At the mo the old lead has a Nasty beginning to it which is not great ! See photos
3. My abilities to do this !! Rome wasn't built in a day...Well I wasn't on that Job anyway !


Thoughts before I turn something on are...

Machining well that will have to be slowly done and hopefully somewhat carefully. I have a very small lathe with carbide.
End float etc..well Im going to put a Dro set of scales when they turn up from East..Hopefully a different man from the west will NOT put them in my Post box ! so no really worry about the backlash, however when i crank with a drill attached to the lead at the mo on change of direction theres a massive amount of slack in the lead-screw to the drill. My guess is that is not so apparent when you have the dial and crank handle on. But begs the question of do I need to worry about this ? If i did have to then bearings at both end of the shaft would deal with that  angular contact type ..with a mounting point on the left holding the leadscrew before the stepper thus supporting the screw and keeping it perfectly balanced and centred and no end float ...But god that seems very complicated. Please guys say thats Crazy your not building an Aircraft engine !

My abilities Umm they are in Question but You can only do your best with what you were given..I don't mind failing whilst learning. If it were easy everyone would be doing it right.

Any advice help tips Patreon, donations, Youtube, endorsements, Brand Promotion, adds,Banners, etc etc welcome !

All else fails just 3d Print it !!
