I made collars out of aluminum. I made the holes .003 undersized and when I need to put one on a tool I’ll heat it till it drops on the shank and when I get it where I want it I’ll either let it air cool or I’ll quench it with cool water. With .003 of press fit, there’s no way you’re going to move it unless you hit it with a hammer.
You can buy GOOD PARTS or you can buy CHEAP PARTS, but you can't buy GOOD CHEAP PARTS.
The bolt on the bottom of the Shars r8 shaft does not fit inside if the bottom of the Maritool face mill. It is too wide.
Did you get a different bolt from Maritool, turn the Shars bolt head down to fit, or just leave the oversized bolt head and tighten it down?
Thanks
My maritool face mill came with a bolt. Fits great.
Maybe they forgot yours?
Just need to cut this shank down a bit.
So what did you guys think of your new shell mill? I am still loving it and I haven't had any issued with storing it in the ATC during production runs!
I just got mine ( 3 1/4” SM) put together and am anxious to try your feeds and speeds with (3) inserts in it.
That is good your atc is working with your SM
My atc runs well for a few months with the same tools in it then out of the blue it will push a tool through the holder. Lost a $70 thread milk this week due to it.
I can’t imagine what would happen if it was the 3” SM.
Do you have any updated feeds and speeds?
Thanks
Nathan

Well, finally got mine up and running this weekend.. And boy have I been missing out!
Fast, solid, quiet and a great finish. I have the 2.48" one running all 5 inserts. I feel like I am barely pushing it running 2500 rpm, .003 ipt, 37.5 ipm, no coolant, and .025 DOC (1 pass, vs 2 i was doing with the superfly)
Once I finish this job up and have some free time i'll see how far I can push it, but already seeing a huge improvement.
I am running a 3" WOC at 0.055" DOC, 40 IPM and 2500 RPM. The finishing pass is the same recipe with only 0.005" DOC.
I just got my 3.15” SM going today.
Great finish!
Wish I had thus before I went through (4) superflies
I’ve been doing .035” doc at 2500rpm with coolant
Are other folks running coolant?

yup, I prefer to run without coolant too. Just as you said, slightly better finish and no mess from the coolant.
Hi folks,
I am willing to try Shell Mill 45deg X 3.15 dia on my Tormach 770 series 3. How can I fit Maritool Shell Mill to a Tormach TTS-1/2 in. Shell Mill Arbor as TTS is compatible with shell mills only 1/2 in. R8 arbors whereas Shell mill has 1.00 inch arbor hole?
I also have an ATC.

Thanks very much
@mega128 I think people are using a 3/4" shank like this: https://www.shars.com/3-4x1-face-shell-mill-tool-holder
Along with this collar ring: https://tormach.com/tts-collar-32432.html
The collar ring slides over the shank (light press fit), et voilà, a 3/4" tts holder with a 1" arbor hole
You may have to turn/grind down the end of it; not sure. I'll be trying this in the near future
Or I might try the import route first; there's a seller on aliexpress that sells a TTS holder with a 22 mm arbor for like 20 bucks, and a 3" shell mill to go with it for another 35 bucks
Are you referring to these:

I ordered one around 3 months ago and I was so impressed that I ordered a second as you can see.

Unfortunately the shell mill, ordered from a different company, got lost in the post and I just received a refund at the weekend. Which shell mill were you looking at?
Step
FWIW I purchased 50mm and 63mm shell mills from eBay. See 291765864789 for the 63mm but I don't see the listing for the 50mm one. I use both daily for aluminum on my 770 with two SEHT inserts (the same insert as the SuperFly) and get an excellent finish. Search for "seht1204 50mm" (no quotes) and choose one with a steel rather than aluminum body.
