I have a Techsew 2700 cylinder bed machine. Reliable, no problems with it. Doesn't get used heavily since I don't do a lot of work.

His post says "I’m selling it at $1200, exclude shipping" Note the seller is located in Indonesia.

I don't see your note about whether you ship will ship and any restrictions as to where. Also question why your IP address says New Zealand and your profile says Ontario? Please update this thread else I will be locking it and archiving it.

Specs in the opening post says foot lift is 13mm, about 1/2". So should be able to handle 3/8" thickness.

If using pliers, use flat jaw type. No grooves that may mark the needle and begin a crack causing a break if slightly twisted. Straight pull, no bending action.

You need to state if you will ship, where to, who pays. See the marketplace rules here https://leatherworker.net/forum/forum/70-announcements/

Maybe you could provide a little more information and pictures to help identify it and see what condition it is in. Here is some information from an old thread.

It was privately printed by/for Bob Park, not by a publishing house. No ISBN number.

That is similar to mine. Below is the style my Dad used (for valve in block). Neither of these would make a good tool for Chicago screws.

The 25 kV line down my back lane (Calgary AB) is 3 conductors only. Drops are made to transformers along the way. The transformers are connected between 2 phases (resulting in single phase delivery) on the 25 kV line, and deliver 110V - 0 - 110V via 3 conductors. (The 0V lead is the N (neutral typically white) conductor.) Overhead drops to houses are via triplex cable. Connection across the two 110V conductors provides 220V which is typically used for heavier loads like electric stoves, clothes dryers, air conditioners and shop tools like table saws and air compressors. As the 25 kV line continues down the lane, transformers are connected to the next pair of phases, and onto the next pair, providing a balanced load on the 3 phase system. It is more economical to use 3 phase transmission as currents flow counter to each other as you look at the actual current flows, reducing the cable diameters versus what would be needed in a single phase system to transmit the same amount of power. In commercial and industrial applications, utility power (110V lighting, receptacles, small motors, etc.) is often distributed as 208V three phase wye connected. 120V power is available by connecting to one phase and the center tap of the wye connection. 120V and 110V terms are used interchangeably, as is 220V and 240V in many discussions and specifications as they are within design tolerances. During my electrical education many years ago, what we now call 110V or 120V was simply called nominal 117VAC.

Yes, about 2 hours, to protect the integrity of the forum.

I guess it depends on the style. One my Dad had, had a screw handle on it instead of a lever. The one I have reaches around the head (valve in head) and has a long cumbersome reach for something like this. The screw clamp reached in the side of the engine block for the valve in block engine. This would be the type of clamp, locking pliers, vice-grip (multiple trade names) to modify to make a long reach Chicago Screw clamp. Has lots of height, lots more than needed, could be lengthened for longer reach, and could be modified so one side can be slide inside a small space. Wouldn't be too hard to do. Make ends like the Weaver clamp. I had a welding clamp very similar to this one. Maybe wasn't designed for welding as the spring failed! Probably didn't like high current flow circulating thru the clamp when the 2 objects being welded didn't have a good electrical connection. Gave it to my son along with my 325 A AC welder and some other welding tools.

Yes, I spent a lot of time in the shop with my Dad, also a mechanic from about 10 years old and up. Figured out how to pull a connecting rod on a 52 chevy 6 without having to pull the head and piston. With the crank in the right position, could pull the piston down far enough to push the wristpin out. This engine had babbit rod bearings with dippers on the cap to scoop oil from a gallery in the oil pan. One rod bearing went out every few months. Lots of practice!

Especially when it doesn't follow the rules!

Loads for me. It has even less reach. It would be relatively easy to modify the reach, or build one with longer reach. Just need to see the idea to make one.

Good mechanics usually beat the flat rate, so could pick up a couple hours extra most days, sometimes more. My brother did really well on flat rate jobs in the 1960s.

Finally figured this one out several years ago. Flammable, it burns, inflammable is nearly explosive. You would call wood flammable, and solvents inflammable.

I use a JP Tack Tool like this. Or like this one.
