Lost in China. looking for an adapter plate for my lathe, Have a engineering outfit in China, purchased some time ago a Lathe made by SIEG (CQ6232E) of the White and Blue line in China, apart from some adjustments, this nothing unusual in China, sometimes it get pushed hard and despite all imperfections comparing it with western type of the lathes it performs remarkable well. It was delivered with two chucks 160 and 200 mm.
My problem, despite China being an engineering heaven and one can buy the most incredible tools very cheaply (you got to know where to buy) and only dreamed to have them in the west, I can’t make out what type of adapter plate is compatible with the machine. Since the Chinese manufactures are only interested in quantities, calling them up, you just get ignored with the answer. The local supplier of the machine knows as much as myself into knitting.
Today I purchased a 240 mm (K12) chuck from HUHHOT Machine Tolls Accessories (AUD 120.00) as need to turn some alloy flywheels, of course unusable till I find out the type of adapter plate. The exiting chucks have a 3 cam-look type of plate. My translator went home for the annual Chinese New Year festivities and makes my mute in China I would appreciate if some of you guys can figure it out, thanks so much

........ some explain Chinese standards like machine tapers dimension, angles, thread types, etc. many are similar to USA types but may be partially metric. Also Chinese were influenced by Hong Kong (United Kingdom / Great Britain standards) like occasionally using 55 degree whitworth threads .
......... these books which some Chinese machinist may never have heard of. I learned of them at a Chinese Hardware store where the picture book with tables of text giving details are often used as a universal catalog of hardware and tools. i have often found an item in the book by the picture and have gone to stores saying "knee yoe ma" or do you have.
........ often a store clerk may not have much education on items sold in the store. i suggest asking a Chinese engineer familiar with machines to look into it. you may need a Chinese engineer and a machinist to measure your machine and make a drawing of it of chuck mount. remember a fax machine can send a picture are common in China. Also i have seen stuff bought in one city put on a bus (bus driver got a tip) and in destination city somebody picks up the box at the bus station (bus driver gets a 2nd tip make sure you get drivers mobile telephone number)
........then i suggest taking a chuck that fits your lathe and going into town with a Chinese Engineer and going to the tool stores of a major city. i find them easily by just asking taxi driver to take you to the biggest tool store in the city. usually in Chinese cities the tool stores are many located near one another. so once in the area you can check many stores.
.........when you find a chuck with adapter that looks like the one you brought with you buy the chuck/adapter and remove chuck to use the adapter. also Chinese used machinery stores which are often incredibly huge in big cities may have hundreds of used lathe chucks that you could buy.
.........also big cites in China can make an adapter to fit your lathe based on drawing you supply usually fairly cheap. i have seen them make some fairly intricate parts for $200 that would easily cost $2000 to have made in the USA.
........if you are in a hurry and do not have money to spend you have little chance of fast success. be prepared to go to one store and sit down for a cup of tea while they send someone to the "warehouse" to get your adapter which is probably another store and they will add 50% to price for their finders fee.
........ i have gotten pissed off because a Chinese store wanted $100 for an ordinary electric vibrating metal engraver sold for less than $10 at Harbor Freight in USA. i went to other stores and could not find other stores that sold them. when i went back to the store the price went up to $120. Capitalism at its cut throat finest.
......... we were paying $100 for ten sawsall blades worth $10 in USA. It was cheaper for the company to order them from the USA and send by DHL mail to China. Some items are rare in Chinese stores because for example a Chinese machinist would not pay good money for an adapter he could make in a couple of days himself. Never saw a bearing solvent parts washer in Chinese stores because they would just use a $1 metal cooking pan and some gasoline to clean bearings rather than spend money on a solvent parts washer machine.
........ might be faster to buy a lathe chuck with adapter and throw the chuck away to use the adapter with your new chuck
