Re: GE 44 tonner

If HO was 1/96 scale then 1/8" to the foot would work, but HO is 1/87 scale or 1 ft equals .13793 of an inch. 2.5 inches divided by .13793 equals a multiplier of 18.125136 Thank You Alco ! I was always under the impression that it was called "HO" because it was HALF of "O" gauge-therefore HO. Sever...

Re: GE 44 tonner

well, If HO is 1/8" to the foot and you want 2-1/2" to the foot , the 2-1/2" has 20 , one eights in it so the ratio is 20 to 1

Re: Torque and it's relation to tramming a mill head

A few comments on Tramming that may help some here . There is is "Tilt" which is left / right and "Nod" which is towards you or away. For tilt you have 4 bolts/nuts and for Nod there are 3 bolts Always start with Tilt when Traming Have Two nuts loose and two with some snug which allow movement but n...

Re: Steady rest Q

I should add that the deflection I add to the bit is a function of drill size
When I am drilling say a .080" drill bit, I maybe deflect the drill .003-.005 " only
When drilling a 3/4 " drill then i have .040-.050" deflection

Re: Suggested method of machinng

Multiple setups using flat bar is simple if you make a fixture to hold the flat bar in a 3 jaw chuck (assuming you have a accurate chuck) The fixture looks like a Clam shell and holds the flat bar repeatedly on center in a 3 jaw chuck so you eliminate that variable. Then you just turn to size and ta...

Re: Suggested method of machinng

As a second thought For a home shop to produce "repeatable' " tight size ....and a half thou range is tight (!) , consider doing all tight work at the same step/moment. For example "If" you had the parts finished except for the diameter , say at + .010" , make a fixture in your lathe chuck that is h...

Re: Plating brass over chrome

I think you want to take it to a plater and have him "strip" the Chrome and then do your brass coat.
It may be possible to plate brass directly, but I believe you will find that surface contamination on the Chrome will cause a poor coat.
The platers always want to strip for that reason

Re: Thin Parting Blade

Harold, I use an ordinary ALoris (real one not import) #7 parting tool holder which uses a wedge for locking the blade, not set screws . I would post a picture but Photobucket is dead and I have not gone elseware. The Aloris uses a wedge and and you can lock down the blade pretty well. Now you do no...

Re: Thin Parting Blade

late to the party here, but wanted to mention a few things. Harold's response is exactly what should be looked at in making a good parting tool. let me add that when doing plastic, you have another concern. Cutting generates heat and unlike metals, the heat is not carried off in the chip necessarily...
