G3102 G3103 Powerfeed

That's great news!!!.... that off color fat shaft just didn't look natural. Lol.


I don't think you have anything to worry bout.

With The grizzly one you pretty much know what your getting into......


It's all layed out here, I would order the grizz and be done.


It comes with shims and everything.

Since your shaft is 16 mm...


Mine is the same.

That is why the 5/8 brass gear hub wouldn't slide on mine.

Like I mentioned earlier. I stuck mine in the lathe and bored it out around .006 - .008 larger. Now it's pefect.


I also cut off part of the end so that I could use my grizz handle... seeing as this kit is really for like a bridgeport or something.



Either way. Your almost theree...... just break out the CC and get er done!!!!

Well, that looks much better with that sleeve off and you should be in good shape now. These power feed kits seem to be made as generic as possible to fit many mills and since you own a lathe and mill you'll get it to fit one way or the other.

This has been a good thread with plenty of information. Unfortunately, all this talk is making me feel like I'm missing out and should quit dawdling and order a feed now instead of later! Bunch of enablers, this place is.

Paypal is ready yet why do i now what to find free shipping..... Man i am cheap.

I am on my way and hopefully in a month or so i can report back the end of the story for all to read later when they ask the same questions.

Well poop. Already pulled the trigger with Grizzly.

I will add that i pulled apart an Acra Bridgeport knock-off mill today (with the permission of the machinist) and found that it is identical to everything shown in this thread. Can post pictures if anyone is interested but did not really see anything new. Just more confirmation.

A quick update with no pictures.

Power feed received from Grizzly. Did a quick test fit and found that it will work but also found missing parts and the brass gear drive is way too long. Trying to work with Grizzly to get the missing parts sent out but it looks like they do not deal in spare parts and want me to send the whole thing back. Not happy about that at all and am deciding what to do.

More later along with some pictures.

I cut off about 3/4" off the brass drive gear...

Used the band saw... then mounted it in my lathe and faced it.

What all are u missing?

X-power Feed is now fully mounted. It is not powered yet though. More on that in a minute.

Mounting the motor was straight forward. Drill and tap two M6 threads and two holes for roll pins. The threads you have 8 holes to choose from in the motor housing. I used the top two as that is what was used in the Bridgeport end plate that came with the kit. Install the 5/8" to 19mm needle bearing sleeve, put the unit up on the mill and transfer punch the hole to the end plate. Remove and tap.

For the roll pins i removed them from the Bridgeport piece and used the Bridgeport piece as the hole pattern. I aligned it to my end piece using the mount screws as the alignment feature and transfer punched the holes. They are roll pins so they have a little give. I was a little off but it worked.

After the motor was mounted the brass gear was next. I had to use every single shim in the kit plus two washers to space the gear off enough so it was not bottoming out the tooth. Note that when i mounted the handle the stack compressed again and i had to add more shims. In the end i used probably 1/2" of shims. If my lathe was up i would have just made a single spacer but....



The brass gear is way too long for the grizzly so you have to turn about 8mm off the snout. Holding the gear in the lathe was interesting. I finally just shoved a tight rod down the center and friction held in on. Worked.



As i said in my previous post, the key for the brass gear was not sent in the kit so i had to make that too. Machined down a 1/8" key to 3mm.

After all that it was all mounted and apears to mechanically be fine.



I am working on the electrical now. The cable was about 6" too short to make it to my buss bar in my VFD box so i am working toward another source of power. Also i know that the limits want to mount where the front X encoder is mounted in the table so i will have to figure out a way around that. The switch can piggy back on the encoder pick-up but the end travel piece will not be sturdy enough on the scale cover. Will solve that later.

Thanks for the run down as your information will soon come in handy! The installation you described was similar to what I expected and because of the Enco deal there's a X power feed sitting on the workbench in my shop.

I realize i am not yet done with X but i have already been noodling on a power Z for the machine.

That is going to be a bit more work though as the stock Z shaft, once the collar is removed has no thread and is about 19mm in diameter. Both make it difficult to adapt a X power unit the same way. Most of the Z kits seem to add a threaded on extension shaft in order to keep the handle. Hmm.... Not worth the $250 right now but i think about it every time i stick the drill chuck in there and have to lower the table 30 turns.....
