Keith I love your new shop and respect and admire all the work you have accomplished, but sometimes the charm of that old beat up lathe with its lengthy ways and the interruption of the engine's whistle touches a smile onto my face.

[@JackHoying]

It looks great! As soon as I get started on the table, I'll definitely take many photos and some videos. Thanks much.

GREAT JOB KEITH !!!!

I really enjoyed watching the making of the acme shaft and nuts to match. I' m looking for a book that explains all details of cutting acme shaft threads and nuts as I need to build a wood lathe for my sawmill for building specialty cuttings of wooden posts and customer different applications. I have been watching your blog for over six years. Starting back when you were working on the old steam train. I would like to build a miniature steamer for my property out here in California. Looking for forward to your help. Thank you Woody

From all Us Looneytoons Thanks for showing how Acme makes threads LOL

[@gunn333]

The Loco Whistle was spot on!!

[@curtisbahr9747]

After watching this I feel confident that I can machine a new cross feed screw for my 16" South

[@nugilum]

The whistle in the background made me smile. Apparently I've missed the museum noises in your videos.

I really enjoy the tight knit community spirit between the You-Tube machining fraternity

I haven't attempted to make threads on my lathe yet, but I feel more confident since watching your video. Thanks for spending the time to make and post this.

[@capitanschetttino8745]

I am amazed at how incredibly educational this channel is. It is a treasure.

[@isabellaman2545]

Two thumbs up for the locomotive whistle Keith. I've been missing that even with the excitement of the new shop.

[@SteveSummers]

Thumbs up! Great little project and video.. Thanks Keith

[@pauljones3866]

Very nice work and thank you for sharing all the tips on machining Acme threads.

Your description of it not making a thick chip but a wide chip reminded me of a MAD Magazine parody of the Boy's Town motto. They changed "He's Not Heavy, He's My Brother", to "He's Not Heavy, He's Just Bulky." :-)

[@ianbutler1983]

Thanks Keith. I enjoy the shop itself videos, but it is nice to see you making chips as well.
