i want to make some T nuts for my shaper's rotary table

I thought for a first project to plane a piece of aluminum on 5 sides.
(i planed 5 sides because one side was milled flat on a vertical mill)
i was successful at making a rectangle.
it is the uncut diamond!

(the milled side is show facing up)

after some initial layout, i mounted the billet in the vise.
i started the shaper, taking light cuts and simply enjoying the click, click, and the watching sweet little curls pile upon the concrete.
here is the t roughed out.
the area marked in black will be a second set of t nuts

thanks for looking!

i managed to do some more work today on the T Nutz.

using a lathe parting tool to start hogging out the t nut from it's billet

then i rotated the billet 90* and started the parting process again.

the t nut is free, but needs some tuning!

here is the billet and the t nut before further refining

next up:
drilling and tapping to #8-32.
i'll be able to render 4 t nuts from this piece.
each t nut will be 5/8" long

Sweet! Nicely done Mike. Did you separate them using the shaper?

Thank you very much Randall,

i had delusions of grandeur in parting the t nuts with the shaper,
then i was stricken by the reality that i miscalculated the distances between the tapped holes and had to go thin blade to reduce the error :bang head:
if you look closely at the nuts you'll see center of the 8/32 is off by .020"in length- oh well!

i could have ground down a tool to do it on the shaper, but i chose to use a hacksaw and files to finish this go around
here is the kicker, i saw a hacksaw attachment that was homebrewed. :idea: after i already did it.
it looked like it would work very well
i may just add the project for upcoming things!

I have seen that hacksaw attachment before. Great looking project. I think it would come in real handy.
good job on the t-nuts. You must have a rotary table project coming up??

Hi rgray,
thank you very much.
i too thought the hacksaw attachment was interesting.
i don't yet have plans for a rotary table project yet.
i was looking for a first shaper project- the t nuts were a simple and gratifying beginning.
but now that i have t nuts, i have every confidence that a project has already left its seed- i just haven't realized it yet :)

UD, about 5 years ago I went to an estate sale in San Jose. The place was filled with machinist stuff. The garage, bedrooms, front room, kitchen…everywhere! In the garage was a shaper like yours in mint condition, maybe never used. I think it was $800? It was still for sale when I left. Looking back I should have bought it. However, I did get all of the accessories that the guy bought for the shaper. The people doing the estate did not care if sold separately or not. I got the little rotary table, indexer thing and something else that I can’t recall. Anyway, was like 20 bucks each. I.e. on other stuff I got: new 6” Kurt vise $100. I made several trips to my truck! Looks like you are having big fun with your shaper!!! I’m jealous!!!...Dave

Thank you Dave, i'm having a blast with the lil machine!
Wow Chips, you should be kickin' yourself for missing out on the shaper :grin:
but on the bright side, the worth of attachments alone are in excess of $1000
sometimes people just don't know what they have, i'm happy that you were able to find a honey hole!
they pop up now and then, if you look for em'

UD, don’t know about your garage/shop free space. Especially after getting that mill and shaper! I have got pile problems. A pile here, a pile there! Shop is VERY crowded with piles! But, I was actually able to put hands on that stuff I just told you about! If you saw my shop you would have said it was a miracle to find anything in it let alone something buried 5 years ago in my shop! And yeah, I know, it won’t be the last time that I will be kicking myself. I walked away from a Baldor cast iron pedestal for a grinder for $100 the other day. It was welded on the top to hold a belt grinder (instead of bolted). The welding on it turned me off. Looking back now, I’m kicking myself once again…Dave.

very nice attachments Chips, beautifully preserved :drool:
