Home Shop Machining in Connecticut

There are hobby machinist groups scattered around the USA including a small HSM group in Connecticut. Our CTHSM group is congenial and freewheeling: no rules, no dues, just people getting together to learn new techniques plus share thoughts on machining and other topics that arise. Meetings are held in member shops, nominally on the second Sunday of the month at 2pm. Anyone interested in attending a meeting please contact me (via the link below on this page)for more info and travel directions.

The March 12th meeting was at my shop in Newtown with 14 members attending. Below are some of the items shown and discussed.



At left is a keyway in a part made with the tool shown. The lathe is used like a shaper with the carriage being moved back and forth while advancing the cross slide a thou or two at a time. The spindle is locked, of course.

At right is a model of a water pump printed on a 3D printer. The work here is mostly doing the CAD design then the printer makes the part. There's quite a bit of detail to this part so the design effort was not trivial.



This is a small Hit n Miss internal combustion engine. The grooves for the piston rings are less than 30 thou wide. This is the smallest Hit n Miss engine I've seen, it will be interesting to see and hear it run when it's completed



At right is an Etalon 5" vernier caliper. Like many Swiss instruments it is beautifully made with an exceptionally smooth feel to its movement.



This is an Elmer's Tiny engine (the pencil is for scale) which runs on compressed air. It was demonstrated at the meeting using canned air of the type used to clean computer keyboards; when running it sounds like a large bumble bee. There are videos of similar engines on YouTube. Plans are available free on the net.



The April 9th meeting will convene about 2pm at Frank's shop in Plainville, CT.
As usual, bring items for demonstration and/or discussion. Plus items for the sale/swap/free table.


Home shop machining is often a solitary hobby, as are most hobbies now according to "Bowling Alone". The CTHSM group is an attempt to getarea HSM's to know one another and thus make our hobby a little less solitary.

The much larger NEMES HSM group is 2-3 hours away so we share some members and occasionally have visitors from that group.

CTHSM Meeting Schedule

The CTHSM group has been meeting since November 2008, mostly on the 2nd Sunday of the month at 2pm, but we deviate from this with some regularity. The January meeting is not held since Cabin Fever conflicts, February has seen a couple meetings cancelled due to weather, the May meeting is on the 3rd Sunday to avoid a conflict with Mother's Day, and we don't meet in July because many members are on vacation. Over time our meeting schedule has become predictably irregular...
