Custom
1.5" lift spacers = 1930's Delta
|
|
This is
a chronicle of my 1.5" spacer lift added to my 1930's Delta
lathe. This spacer has changed my lathe from, an 11" lathe to an
14" lathe. I wanted to retain the look as best as I could
and all the functions of the lathe tailstock. It all started
with a dream and $20.00 worth of steel. The block was 2" x 4" x
12" which would allow me to have the needed blocks once milled
smooth and cut to size. I enlisted the help of a local Voc.
School machine shop (free labor, I am a bit cheap ya know..)
They did a pretty good job, although accidentally cut the blocks
to the same length so I needed to add about 1/2" back on to the
tailstock. I
was in luck to have a chunk of steel in my shop so I put a metal
cutting blade in my Delta tilt-top saw and cut it to size, well
as best as I could with what I have to cut 1/2" thick steel in
my shop! |
In the next few photos you can
see the block for the tailstock and the holes that were needed
to attach the block. First I needed the holes for the u-bolt to
pass thru. I used a transfer punch set to mark the center of the
hole followed by a center point drill bit to accurately start
the hole. This was followed by a few drill bits to reach the
needed 3/8" hole. Next we jump ahead a bit to show the
three 1/4-20 countersunk bolts used to lock the original
tailstock block to the new spacer. I did not want this to be
loose and only held by the u-bolt and cam lock. You can see the
3/8" transfer punch lines up perfect! |

Now off to the headstock... I
had to remove the lathe from the stand to do this part. I
clamped the block to the bed once it was lined up and again
using the transfer punches I marked my holes. If you do not have
a set of these, you can buy them for about $10.00 at Harbor
Freight and they are well worth the cost spent. I also use them
if I need to take apart one of my pens. |

Here is a photo of the tailstock
block after some work on the disk sander to round the corners
and sand off the rough cast iron surface. The headstock &
tailstock are both aluminum so by filling the cast iron surface
the new riser block will appear much more seamless. I did forget
to take a photo of the headstock after it was sanded, but you
get the idea. They were sanded with the matching part bolted on
so as they would be matched to each other perfectly. The second
photos show the headstock all ready for paint as is the
headstock & tailstock themselves. I wanted to repaint them as a
whole to fix some nicks and just to keep it looking fresh and
seamless. In the bottom photos you can see the start of
the repair I had to do where I added a 1/2" back on to the lift
block that the school accidentally cut too short. I did not weld
the entire block up. I did weld both sides and across the lower
tab, but just 2 spot welds on the top as I did not want to get
into the surfaces that were machined. |

Now I have a couple parts in
primer and ready for paint. I will be repainting basically
everything but the bed over. A lathe can take some abuse and
gets chipped, nicked and finish stuck to it here and there so I
might as well paint it while it's apart. I am also painting the
tool banjo but that just needs a quick strip & paint. At this
point all that is left is to finish grind the tailstock block
and make the u-bolt and it's ready for paint work. |

Below are the photos of the u-bolt
I had to fabricate from 5/16" CRS stock. I tapped the ends first
and then bent the rod around a 7/8" tool rest I had which was
almost the perfect inside curve of the original. The rod was
made half an inch longer and extra threads were done so that I
could trim the threads down to the exact length. |

And finally for the
finished product, my "new" 14" lathe!! |
