John If that's a arc chuck them things are hard /tough you name it, took a skim off the dia of mine to tidy things up ( because I wanted the whole set up slim ) at 100 rpm with a light cut with carbide the chips where blue/purple along with sparks to boot . I would not like to drill out the...

If you are running on steam then you must use steam oil for the cylinder/s , use any single weight oil for the rest not to thick on air use the same single weight oil for the cylinder/s Stuart

I should have copied the page alas I cannot find it agin but look on the grizzly site with their number and check out the pic parts and manuals are free to dl Stuart found it here is the quote from the page Later I then bought a Warco BH600G lathe (also known as the G9249 in the USA) and so...

using a bit of google fu your lathe is sold in the USA as a G9249 according to their spec sheet the spindle thread is 2 1/4 8 TPI no comment on the angle though but I suspect its 55 deg as its an imp thread Stuart

if you have used CI then you must use CI rings , soft packing ( graphite ) will not work vey well. I use a 5 thou diff in sizing on a 1 5/8 cylinder on the loco whose boiler is my avatar Its a BR Class 4 tank 2 6 4 about 48 inches long and it is a long job as I build true scale ( rivet counter...

that fit is a wee bit tight for a steam engine , think about when it hot . with a fit that you would not need packing the packing should just fill the grove, when running with the lubricator on the steam oil will provide the seal , just a nice push should be ok , about like the fit you have...

thats a lot of energy in that system you seem to be going ahead without much thought and calculations as to the forces involved by all means use a air to oil pump or a hydro jack /porta pack but direct air no way a quick and dirty calc gives me 1319 pounds on that piston and its stored...

time to get your google fu in order try a search for MXL 90 Z 3/16 its the space that matters between the 90 and Z same for the others Stuart

got to agree with Johns comments I to now make my own holders ( to much variation with the cheap copy ones , not pulling up ) and good guaranteed to fit ones are £40 each so its a bit of 25 mm square bar and away you go the fitt then is down to you I make my custom tooling eg retractable tool...

now that does sound a plausible cause , hard on the wallet though a good clean out and some thoughts on sealing the enclosure from that nasty brass swarf its bad enough when its in your fingers but deadly on a pcb if brass is your normal material I would consider remotely mounting the new...

before you go any further please check that you have not pinched /nuded a wire somewhere when you put it back together from my past experience with these new fangled do dah's that the slightest fault to earth spells disaster, it seems to me to be a coincidence that the tiny amount of magic...

I know its called Tree Wood I get my coat :-) Stuart

To the OP you haven't used that slitting saw on a ferrous metal before because if you have it will be junk for brass and gunmetal just the same as a file or end mill Stuart

Sorry John I was just brainstorming I think the KISS principle is the way to go as of now the job is paralysed by analysis I was looking for a quick and dirty way to do the job without having to change over the chucks not a big job but like you my movement is restricted Stuart

if you are going to put in a feed screw to offset the virtual centre , then why not make a back plate with two keys fitted across the dia. with a groove in the er chuck back plate to hold register and allow movement two bolts as in John's COC , should make a fine work holding tool Stuart

John from little seeds oak trees grow after Bob had posted I was in the workshop and I ended up eyeing up my er 32 collet chuck on its back plate , and The same idea impinged on my one remaining brain cell we must have had the same vibes but yes your idea would indeed solve the problem in...

this forum never fails to amaze me with the quality and diversity of the solutions to a problem Thanks Bob that I can see as a useful device Stuart

Tel and John yes Had one myself yesterday made two part both were upside down and backwards , but the worst part is they would not fit ??? ahh well today is a new day so I will try again , now what was the parts I was making and what for Stuart
