HF Mill
Drill with new Kurt vise & DRO |
My shop started out with a HF Mill/Drill a few
years ago (back in 2001). We have an outlet about 5 minutes away so it was
real easy to inspect before buying, plus it was on sale. The stand was
bought at another HF in Pasadena because it was also on sale. I got two
great deals. It was easy to bring home, just loaded it in a pickup. A few
pieces of plywood, plus an engine host and it found a new home.
After reading the manual, cleaning and greasing it was ready to go. The
first addition was a X axis table feed. Enco has them on sale once in
awhile. Also I added several end mills, boring head and cobalt bar set, V
blocks, Co-Ax indicator, edge finder, parallel set, 1-2-3 blocks and a
magnetic indicator holder with a 1" indicator. Replaced
the Enco vise with a Kurt D688!! This pretty much got me going, I
use everything on the list.
There are several
thing I still need to get or do:
- Convert the power system to a VFD.
|
- DRO Quill, the micro dial works but many
times I lose track of where I am.
|
- I'm looking at the Phase II 6" H/V Rotary Table. So many projects are much
easier to do.
|
- DRO. Added ... see picture above and below!
|
- Reduce the vibration in the motor belts.
Surface finish could be much better.

9x20 Lathe with modifications |
New shop addition...Enco
9x20 Lathe!!
(2/03)
After much thought and planning I
decided that a small size lathe was in order. There were so many projects
that require turning that I was missing out on. Due to limited space the
9x20 was chosen. It fits nicely on the left side of the garage between the
wall and a big Suburban; just enough room to work.
The lathe is sitting on a 7 1/2 inch slab of cement, this is to help reduce
vibration and bring it up to a comfortable height. The slab has reinforced
steel rods and is bolted to the floor. The stand was set in wet cement and
bolted in place. Finally the lathe sets on aluminum plates that were milled
at different angles to level the lathe in the x and y plane. Seems to work
fine.

4 Modifications to the Top Slide |
Like so many new machines there are modifications that are required
to make them perform better. After reading many posts on the Yahoo 9x20 Lathe group,
I ordered a Phase II wedge type tool holder. This was installed before I even powered up the unit.
Installation was easy only requiring to re-drill and tap the hole in the plinth. Works great!!
I have have made two other modifications recently
(01/04).
(Sorry no pictures).
The 4 bolt clamp and the top slide bearing. For details both can be viewed on
Steve Bedair's site.
The 4 bolt clamp made a BIG
difference. Surface finish was greatly improve and the vibration
significantly reduced. Before it was installed I would avoid doing parting,
the tool would grab the material making the clutch slip. No matter how slow
I went or how much lubrication was used, it didn't matter. Now ...
not a problem!
I am hoping for an improvement in threading also. We'll soon see. To get a
smooth surface I would sand and sand until my fingers were black then
polish. Now sanding has gone way down and in some cases I don't sand at all.
Great mod ... try it.
The top slide bearing is another good modification. I can now tighten the
gib and still have a smooth slide operation. Instead of the lead screw
rubbing against it's mount (metal to metal), it's against the inner race of
the bearing. The roller bearing works because the forces on the inner races
are small. This mod requires a little more work to get everything aligned
correctly, but it is worth it.
The
Lathe Crossfeed, Mount and Bearing Modification
(12/16/04,
update 10/6/05) is another worthwhile change.
Additional support items for the lathe and mill/drill were needed. To the
left of the lathe there is a 18"x24" surface plate with a protective wood
covering. When trying to make measurements or do layouts I always had
problems with getting accurate and repeatable measurements. Normally I don't
buy too many things on ebay, but since I was able to actually see it before
bidding, I had to try. Got it and the stand for about $100; grade B in super
condition. No shipping! With the surface plate, along with a Fowler Height
Gage and .0005" indicator, measurements and layout work is easy and accurate.

HF Band Saw |
Bandsaw and sander added to shop!!
(04/03)
How do you cut a 2" round steel stock or a 1/2 x 6" plate?? Crooked, after
an hour of pushing a hacksaw around. It didn't take long before the need for
a bandsaw and sander was realized. HF to the rescue, again able to see and
on SALE!! No real modifications yet, works great. Motor does get hot,
but with careful monitoring it should last a long time. Bi-metal blades are
now install and really do the job! A cooling system, stronger legs and
wheels are in the future.
I use the sander to de-burr and reshape various material. It's handy and quick.

ACU-Rite Micro-line DRO |
Acu-Rite DRO added to the Mill/Drill
(06/04)
After attending a show in LA, I saw how easy it is to use a DRO on a
Mill/Drill such as mine. Well it wasn't long before the need(!!) set in.
This DRO is 2 axis ACU-RITE Micro-line with a resolution of .0005", accuracy
of 10um/m. It has full bolt hole pattern, Centerline Calculation, Zero
Reset, Preset, and other little goodies that make machining much more fun.
It took about 4 hours to attach the scales and mount the readout in a good
location. It's easy to use ... find datum, move to the coordinates you need,
lock table and drill. Need to move 4.0025" over, just place it in
incremental mode and move. No worry about backlash or how many turns of the
dial were made. It's really nice!
Well, that's my shop for
now. As new toys (ahem ... TOOLS) are added, I will review them and let you
know how they work.
