Boy.... that fwd/rev handle looks crazy close to hitting the table????

Ask @David_R8 to send you (or publish) his 3D printer file for the end cap to cover the brass gear.

It touches the table in the very corner! I don't think it's stopping it from full travel, but I'm either going to turn the black knob 90 degrees or make a smaller knob. It doesn't seem like the knob is threaded but I didn't try very hard.

I am going to try and make my own cover as I need all the practise in fusion360 that I can get, but if I fail I may have to ask for an STL file

Ya gotta love having tools to help make tools.
The first pic in post #17 looks like Pinocchio.

It was either drop I think $380 from AliExpress for the bolt on horizontal version, or $160 from vevor and some figuring out.

They sure are proud of the horizontal bracket. I lose a touch of travel but I didn't lose any or much space beside the mill which everything along that wall is crammed in basically tight so

 

[Jswain]

Made a stepped spacer for the bearing in the power feed to ride on, & to set backlash on the gear, and also spacing it out from the metal plate mounted to the mill.

I have no idea what to set backlash to on the gear, but I went with juuust a little bit.

Either tonight or tomorrow I am going work on the limit switch mount. Looks hopefully easy enough to just remove it's current plate & cut off the mount, make my own & weld it back to it so I don't have to drill any new holes on the mill itself.

 

[Jswain]

Made up a quick bracket for the limit switch to mount on. Will probably mill a different one out of s'more 3/4" plate but didn't have the Allen head bolts for it.

I get about 18" of travel, and I set the stops close to an inch before the end of the leadscrew or any contact so I think that'll do just fine.

I turned the knob, but it still just touches so I may make a new one after the cover is finished. Printing it now

 

[Jswain]

Removed the handle and gave it a little tweak in the press brake, lots of clearance now.

Also V1 of the cover mounted, V2 is on the printer now once I finalize it I will probably print in black

I'm really surprised you were able to bend that handle with out breaking it...

I ONLY attempted because I seen it was threaded on, so figured worst case I unthread & make a new handle, but it bent quite easily!

The rubber handle is not threaded however just pressed straight on a shaft and man it was hard to remove lol.

V2 off the printer and on, like it enough i'm gonna sit on it for awhile, may reprint in black next time I change filaments. Fitment is great and works for a quick handle too if needed.

Thicker wall sections, and a larger knurl then v1 and has a lip that inserts between the brass gear and the housing

My soon to be t nuts to mount the 4 jaw to my rotary table. Thrilled at the surface finish difference using the power feed

 

[Jswain]

Success! Of course the bolts were too large for the t nuts, but I liked the thought of the larger m10 shaft/head so I just cut them to length, turned them down, and threaded them for M8 x 1.25.

You think I could get the die started though...not a chance, pretty sure the start of the die is dull. Tried out my very first time single point threading on the SB9 & worked out just fine. I took it to about 90% then finished it off with a die.

If I plan to leave it on the rotary table I should be able to center rotary table on mill, then center chuck bolt it down and then I only have to worry about centering off the chuck when I throw it back on the mill?

I switched over to a 3/8 roughing mill to cut out the sides just to try it, the mill definitely enjoyed that. Finish was good enough I just left the roughing mill in

Just a neat video, related to your mill type.

Crazy a little M12 bolt with some preload would make that much difference.

One of the hopefully very near future projects is a new base for the mill. I have a bunch of 1/4" plate so I'll probably use that. I love the cast iron table it's on but because all of the webbing underneath I can't drill it to bolt the mill down. Plus I'd like to build it enclosed, with a door for storage

That right there could be our group moto..... Simple and sweet. Only a machinist would look at a bolt that way and think that.

Glad to hear you ended up single pointing. I would not have even tried using a die. I'd rather single point all day any day.

Very nice job.

I've been avoiding it for a long time, and I don't know why it was actually quite fun.

I was curious today so I tried his test after cleaning up the RF45.
I'm a bit relieved, compared to his anyways, I can only get ~ .001" up or down with all my weight on the head. That was with the head down fairly low, like 3/8" endmill just above the vise, maybe I'll try again with it up higher

Good numbers.... try higher. See what results you get !

Little hot glue gun action

 

[Jswain]

Starting to take shape. Going to box it in with 3/16" plate & put a door on it. Hopefully get that done tomorrow and start working on some levelling feet

 

[Jswain]

Sheathed in 3/16". Either I'm getting weak or it's getting heavy. Got the door cutout just gotta figure out some hinges & probably weld a half deep shelf halfway up ish.

Probably going to fully weld all the seams to keep the dust out

 

[Jswain]

Got every seam welded on the inside. Welded the back & bottom inside & out, going to leave the sides & top stitched I believe because I like the look.

Welded a 16" long shelf in 12" down from the top. The anti spatter gives the metal a nice black look, I think I will leave it unpainted for now as I'm sure over the next year I will think about more crap to weld to it.

For now I'm thinking an r8 rack on the inside of the door, maybe a small shelf or two for endmills/cutters?

Don't have any stock that will work as is for hinges/levelling feet so will let the dust settle tonight and make some up tomorrow on the lathe.

I also believe I have enough square tube to make wings that will slip into either side at the top to act as a chip tray so I may make two of them up and put a plywood insert in them, we'll see

 

[Jswain]

Made up some weld on hinges and going to try and tackle some threaded feet now
