Your Heads also look gorgeous -did you do those on the mill with a slitting saw ? Rich

Bruce, You got it ! If I may ,I think I can speed up your process (60 years in a shop) Always do the X axis first ( L & R) ( 9 and 3 O'Clock) ( We called it Twist or Rotate) Then do Front to Back (called Nod or Tilt) .....but know this Many guys try to do it at 6 and 12 O'Clock,,,..don't ...

I still have my drawing sets and maybe Ink. I have Mylar if anyone wants some..free ! ( you pay the post ) Dave, How did you get AutoCad 95 to work in Win 10 ? I still use 95 and have an old XP PC to run it Rich

Peter, the point I was making was keeping the cutting load centered on the support provided by the cross-slide AND tool-slide areas. Removing the tool-slide function as shown in your pics is also a great help as it removes another "Flex" joint in the assembly . No doubt a lathe without a...

The main reason a rear Toolpost functions well is that the load is supported "within " the cross-slide ways. This is important for newbies to understand Rich

One thing I do not see here is how to set your tool height ! If you do not have a 6" aluminum scale, get one. Steel scales work ,but tend to be slippery when used and drop into the chip tray This works for any Lathe Tool Place the scale between the workpiece and the toolbit and gently bring the...

Tornitore45 has it right ! You can use a tailstock or steady rest for help in parting-- but not through ! How much so--- is dependent on the rigidity of the Lathe ---and the Live Center !! If you push on the workpiece and you can move it......beware ! The more "flexible" the workpiece , the...

Late to the party here, But always looking for simple fixes. Are both the bearing inserts (front and rear) the same ? Can you reverse them ? On the front bearing , can you flip it bottom to top ? By moving the bearings around you may solve the drop . On a side note, try to stay with Tin or Tin...

Don, Doing your gear is not impossible There is so much good information available to help you in your endeavor I think the best is work articles by the late "great" John Stevenson Go to post 6 on this thread where I list the resources...

Goldstar It's a Boxford Lathe ( Which is the British Version of the Southbend...but Greatly improved !) I rebuilt mine (scraped the ways) and it is a bit different. The "Legs" of the carriage were ground parallel to the cross-slide ways, so when (but I never did) I put a Boring table on the...

So let me try this to help the thread and first show the concerns a machinist has to start a parting job This is shown in the first two pictures. The 3rd and 4 th Pictures illustrate what are positives for parting. Please note the last photo shows why a rear tool post in mostly succesful because...

There is confusion in understanding investment materials - promoted and caused by books and articles and by postings ! It caused me multiple failures years ago, and I commend aonemarine for pointing it out. Pay attention Folks ! The misnomer is the word "Burnout" Please know this , Raising the...

I don't have a Picture File since Photobucket went bonkers, but have posted some relevant pictures for Parting tools on another forum -go to post 25 on this thread https://bbs.homeshopmachinist.net/forum/general/1836740-parting-made-easy Rich

Absolutely Bob There is one other VERY important reason not mentioned Rear tool post parting tools are mounted in the "Center" of the cross-slide ( Stability +) Which means the cutting load is vertical (Upwards ) and the dove tail counteracts it EVENLY. but normally many Parting tools are...

Bob, Nice sketch and fits perfectly with my comments about parting off, so i will refer to it. Parting off seems to be the biggest bugger to many home shop guys. There are many reasons for problems, and most relate to slop or play in the gib surfaces. There is also some spindle related issues...

Ben, Is the material you used for casting A 356 Aluminum ? Beautiful looking Engine and your graphic work is superb ! Good description of the Planetary /Flywheel math relationships. Rich

Late to the party, but I have seen similar drill damage to the flutes when the drill was accidentally run in reverse. Enlarging holes with minimal increases is common in industry, but feed rate becomes more critical as the drill wants to pull due to the helix angle Rich

First, The Table OD and ID must run true. 3 of my tables run true ( 2 -8" and a 12" ) However, the 6" unit was off, so I chucked it up (table only ! ) in the lathe with a DTI indicating the WAY surface, then I re-bored the center hole concentric with the ways. You could also bore the hole in...

Too much DTI use for setup "IF" the stock is square or rectangular, try this Set the lathe for about 100 -150 RPM and use a magic marker Bring the marker upto the work piece and the high point will be marked immediately Tighten the jaws on either side of the high mark. (loosen others ) Repeat a...
