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 August 9th meeting was in Newtown, attended by 16 people. There were more projects and items shown than at most meetings so there are more than the usual number of pictures below.




Dog Clutch Optical Punch At left is a dog clutch based on Jim Schroeder's version of Graham Meek's design.


At right are two versions of an optical punch.


Air Tank Air Tank These are the air tanks for a steam locomotive model's brakes. One is for the brakes on the locomotive, the other is for the brakes on the cars the locomotive is pulling.



Edge Finder Wheel Dresser At left is a P&W edge finder. This is placed on the edge of the work and a DTI in the spindle touches both sides of the top slot; the table is moved until the reading for both sides matches, when the spindle is precisely above the work's edge. Similar to the way the B&S edge finder works.

At right is a shop made wheel dresser for use on a bench grinder. It is clamped to the tool rest and the diamond is moved across the wheel with the leadscrew. The diamond is advanced (its holder is threaded) and another pass is made until the wheel is true.




Countersinks Split Nuts At left is a set of shop tools including countersinks, hole punches for leather etc., and a chuck similar to a lantern chuck along with adapters to hold screws so they can be shortened or the heads polished in the lathe.

At right is a set of split nuts covering the common imperial sizes. A machine screw or bolt is threaded into the nut and when the nut is gripped in the lathe chuck the slot closes, preventing the screw from turning in the nut - this allows the bolt to be machined, much like the lantern type chuck shown at left.


Spiders Engraving Holders At left are a set of lathe spiders.

At right are samples of engraving work plus two specialized holders for engraving. The holder at left allows rings to be engraved on the inside - the copper ring shows how it holds them. The holder at right is held in an engravers vise; the work is waxed or glued in place on this holder which allows the work to be rotated easily.



The September 13th meeting will be at Frank's shop in Plainville.

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...
