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 May 17th meeting was at Ralph's shop in New Hartford.




Ralph's Locomotive
Ralph's locomotive on its purpose made table; it rolls easily on the rails affixed to the table.
The table height was chosen to ease loading onto a truck for transport to the location of the track it will operate on. The table has wheels too, allowing it (and the locomotive) to be moved about.


Mill Duplicator Radius Cut At left is a duplicator for the mill. It clamps to the spindle and the bearing is used to track the item being duplicated as the table is traversed and then indexed and traversed again. Apparently useful for certain specialized projects.


At right is a sample thumbscrew with a radius section having a larger radius than the cutter used to make that radius. This magic happens by tilting the mill's spindle. The spindle tilt angle for the desired radius can be calculated from the formula shown.



Bench Squares ID gages At left are two bench squares. These are often made as a machinist's class project. The larger square has the maker's name stamped on the top.


At right is a set of gages used to measure the ID of small holes. These differ from the more common ball or half-ball gages in that they use ball bearings that protrude from the shaft, where the amount they protrude is set and locked via the knurled handle. These gages can reach deeper into holes than the more common types.


Bike Rear
These parts will be brazed to the rear of a bike frame to hold the rear wheel. The slot allows adjusting the position of the wheel slightly so it tracks properly. They were cut on a CNC mill, allowing them to reproduced for low volume production.



The June 14th meeting will be at Eric's shop in Tuxedo, NY. We'll meet initially at the Energy Building of Museum Village in Monroe, NY at 2pm. The museum opens at 11am so early arrival (optional) will allow touring other areas prior to visiting the Energy Building. After touring the Energy Building we'll visit Eric's shop which is about 15 minutes away.

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 get area 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 for several years now, mostly on the 2nd Sunday of the month at 2pm, but we deviate from this with some regularity. February has seen a couple meetings cancelled due to weather, the April meeting has not been held since Cabin Fever's new schedule conflicts, 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...
