Retire 75 yr old have had some experience in machine, love to make things, getting more involved in math calculations and more detailed like engines, cams gears. I built fixtures and some plastic mold repair.
So I get lucky sometimes as when I click on a link from the listings, inside there eBay puts up links with photos to other sellers of similar items. I've gotten lots of insert tooling lately from China.
Now you will see the Aloris brand, high quality, but 4x-8x the price. I've not seen anywhere in my shop that that is needed.
Hope you see this private message.
Look at eBay, and Amazon, and do a general search for QCTP sets, if you don't have one on your lathe currently. I shop around. But even there, sellers on eBay may have a spelling error, or they don't have a keyword that you think is required.
As for the piston type, they just don't have the tool holder power. I've bent the height adjust screw (twice now) which is a long set screw into the holder with a large knurled wheel threaded nut. I did this on my large lathe, that is a geared head, and I was treppaning at the time.
ajoeiam: I just did a search for "QCTP number system" and I got a link to Phase II brand catalog online.
I've 3 sets of these. One is unused as it is the piston type. I have the 1xx size for my 10x24 lathe, and 4xx size for my 18x40 lathe. They are Phase II. I've been getting holders from Shars. I think the best price is from eBay, that I've found.
You did not mention where you live. If snow load is a problem then you would need a high pitched roof. Why steel, a wooden structure should work well . The roof itself can be covered with shingles , metal sheet , or in some cases Fiber glass translucent panels.
I am now completing the ME Beam Engine, and want to make a model (perhaps a Farm implement) tht my Beam engine could drive,
Any advice any Member could assist me with ideas would be of Huge assistance. Thank you
My shop is getting a major upgrade. My 1963 Bridgeport is being replaced by a Prototrak DPMSX5 and my tired old South Bend is being replaced by a Prototrak TRL1440. I have a lot to learn with the conversational SMX and LX2 controllers, but it ought to be fun!
I'd very much like to buy your Sears Harvard casting set. Please consider my offer of $500 plus $30.00 to cover USPS Flat Rate shipping to Chino Hills, CA. Out of curiosity, are there any drawings with it? Thank you.
Hello 74 Sprint
I would like to make the circuit you designed (Hall_effect Ignition Proper ) to replace the original trigger in CDI ignitions with a Hall sensor but did not understand how to connect the Hall sensor to the 2N2222 transistor
The positive of the Hall sensor goes to + 12Volt, the negative to-12V, the signal must be connected to the transistor base?
Thanks for your support
Hello Mike I notice that you live in the UK and your name is not a common one , so this makes me wonder if you by any chance are the Mickey Ginn who organised rock climbing trips to Morrocco back in the late 60's . Quite a long shot I realise but stranger coincidences have happened.
