coles power models has cast iron rings for $5-10.

i usually set the gibs just tight enough that i can definatly feel the backlash in the adjustment screw then tighten them down pretty good for cutting. i think getting about the same tension on the adjustment screw each time is pretty important when trying to get an exact diameter.

its been my experience that when boring in the mill with a boring head the limiting factor for speed is the rigidity of the machine, because the tool i not balanced. i have a large mill and i feel good at about 100-150 rpm regardless of diameter/sfpm.

sorry about that, i came up with 6.15m=23.somethingft yesterday for some reason

just a side question. why is metal sold in 6.15m standard lengths in the UK? it seems like an odd length, i could see if mabey if it converted to some even number of feet.

i think this would be a good place for a bellcrank. should transfer motion really close and would result in alot less side load on the vertical shaft.

you can push the broach through with the tailstock on your lathe if it can take it. my grandpa says they used to cut internal keyways by grinding a boring bar the right size and running the carrage back and forth instead of using a broach, similar to a shaper, i guess you could do something...

the weight of the balls will effect the speed because hevier balls will have more power to compress the spring more, closing the valve and slowing the engine. at the low speed of a carosel the difference may be so small that to the observer they may seem the same. also the ratios and...

almost everything grizzly sells is also sold under other brand names, with minor variations if any, grizzly sells shop fox brand id say they probaby own the brand.

Dan is right 32 tooth at top, then 127, then 48, levers at NS, knobs at AC. the number of teeth in the middle gear is irrelivant because in this setup its just an idler to move power from one shaft to anothe so has no effect on the overall gear ratio of the train, all that matters is the first...

heres a photo of the chart, i think the one you where looking at is the D.P. chart, i dont know what that is exactally but its not what you want.

i thought the sae thing jason but i looked at it last night it just shows the chart for metric threads

i happen to have this lathe also and if i remember right since i cant look at the moment,the 48 tooth gear is used for most standard threads with the exception of a few that use the 52 tooth. also i believe that only one part of the double gear is used, meaning either the 120 tooth side or the...

in this case would it have been possible to drill both of the end journals and build a simple line-boring rig for the intermediates?

mine is a 10 or 12" so it may be different but on mne there is a short shoulder between the surface and the mt3 i made a "washer" that fits tightly in the shoulder area with a hole in the center for whatever size im using. i also sometimes locate the center with an edge finder, zero the...
