Another Ball Turner using a BXA boring bar holder with bushings and a cheap boring head. Added pins on the back side of the holder and adjustable collars to limit the swing of the turner. Does require the compound to be set up at an awkward position for the cutter to reach center, think I'll make a shorter HSS holder for balls under 2". First ball turned always becomes the ball turner handle right?

With this type of ball turner do you run the lathe in reverse? It looked like the cutting tool was above the ball in one of your pics is why I asked.

The best threads that I have ever made on a lathe. It is an arbor for an electric motor. The threads are 1/2-20. I have an old craftsman 1/2 hp motor with dual shafts. Its going to be my buffer, so I will be making 2 of these.

Today I added a DIY X axis feed motor to my G0758 mill. I consists of a Dewalt 12 volt 2 speed cordless drill motor, a cheap speed and reversing controller, a couple pieces of 3/8 all thread, 2 pices of 6061 4" x 3" plates drilled and bored to fit the diameter of the the chuck and motor end. IMG_0078.JPG

I simply tighten the chuck as you would if it was still on the drill so far it has worked well the speed is pretty slow and there seems to be plenty of tourque at the slowest speeds. here is the controller put it in a project box IMG_0080.JPG I made a temporary covering out of some flashing IMG_0083.JPG
I used a 12v power supply @ 30 amps IMG_0082.JPG

Today i had couple of projects to do on the lathe, i started on the pulley for the lawn mower engine, first i face it and clean up the smaller end, center drill it, then drill it thru with 6mm then 10mm drill and drill it with 21mm drill bit to 25mm depth, then i used a fresh brazed carbide boring bar to bore it to size. Then i faced the bigger lobe, i stopped on this pulley here because i had couple other jobs on the lathe to finish, one of which was to drill the valve plate for the little 4x4 , i used and old drill press spindle with a MT2 to hold the drill bit in the lathe chuck, and the plate in my tool holder, started at 400 rpm drilling was a bit slow, so i speed it up to 1250 rpm and finish the drilling quickly, then i drill 8 more small holes to the side and threaded them with M5 x 0.8 , this left shards in the hoes for the dail indicator, so i run a reamer to clean them then i went to the big garage and test fit it on the engine, you can see it holds a dial indicator so i can set the valve clearance accurately, i'm sure this engine has never had his valve clearance set since it left the factory, do the valves sound like a drunk drummer playing.

Different type turner, his goes up and over the ball, rather than side to side...I believe..

As always , what I TRY to make is ROOM in the shop . Found some angle grinders in a bottom drawer . Not necessarily hobby grade . Couple of B&D industrials and the Matabo . Yard sale coming up ! 1 or 2 of these Vidmars needs to make a trip over to the islands this summer , and I'm making slow progress ) :( That little HF grinder bit the dust a while back . I think it got over worked ! :grin:

very neat! Any details/ source on the controller? I've been musing about doing something similar but finding a decent controller is tricky. Is that a 2 speed drill motor? Also, do you get any twist from using only 2 threaded rods (or is there a 3rd behind the motor)?

I installed a couple of inexpensive DROs on my 9x20. I can get them to register .0005" of movement even though the rated accuracy is .001" - which may actually be true but I didn't expect that they would increment in .0005". Not too bad for $60.

View attachment 262565
The native resolution of the capacitive scales is 10 micron (.01mm or ~ .0004"). There will be a rounding error in the conversion to inches when resolving to .0005". The error is negligible when resolving to to .001". You can avoid a conversion error by working in mm.

Almost all digital measuring devices will show 1 more place of resolution that they will commit to in specs. The ones that don't are probably just suppressing it. I think this is an artifact of converting from Binary to base 10 and also may not be repeatable at the least significant digit display. in other words, just because it is displayed does not mean it is accurate to that level.

Two simple projects to make life a little easier...

I replaced the chinesium hand levers on my little single lip grinder with stainless ones from Kipp Germany. Much better!

Next, I turned a new bushing so I could use a soldering stand with my baby 12w iron. Had a block of mystery plastic, now I have a good place to rest my pencil iron.

here is the controller I ordered, just took a chance on the quality seems to be working well.

yes that was a two speed motor I figured it would have better torque in the lower speed so I keep it there. I only used 2 rods the motor doesn't twist at all. I actually considered 4 rods one on each corner but after trying it with 2 I decided there was no need. I forgot to mention that I put set screws on the top and bottom of the plates to make sure it didn't twist in the bracket.

cool, thanks! If you want to add a Rapid function (full speed momentarily) to move the table in to position, you can use a momentary switch wired between the center wire of the pot (wiper wire) and the high range wire (if high resistance = high speed). Then when you press the button you essentially "short" the pot and the motor will run at full speed. It's what I'd do if I built one as I use that function a fair bit on my X-axis power feed.

Last couple of days i've been doing lots of odd jobs in my machine shop and on the Little 4X4 and shoveling snow, we got a record amount of snow and cold. On the Little Niva i've done some more body work, on the wheels arch and on the trunk lid, because of the dashboard eating more then half of the new body filler i bought now i'm scraping the bottom of the can, that said, this little russian car is much easier to apply body filler then on french and german cars, there is no flex in the sheet metal. I did most of the work in the big garage around the warmest time of the day and continue working in the afternoon in my machine shop, because is smaller and there is heating, one of the odd things i did is to make a plug and drill ( take some) material out so i can use my lathe as a shaper to make a key way, and my cheap drill press dissipated again, can you see how crooked the hole come out, the table is set straight and that is a new sharp drill bit. Then i moved on to making some wheel nuts, the little niva needs couple but even that did not turn right, the 19mm key stock was defective, i was surprised at first when i broke a new high quality insert on just facing it, but did not see the crack, i made one complete nut without problems but for the second i heard it catch and when i looked it has peeled back, i looked at the other 19 mm stock and all of it had the same crack, i'll need to take it back to the steel place, i'll also need to work on the heater i started on for the big garage, this weather is not letting up.

finished a major job this week - adding new lights and a fan to the kitchen, partly because I wanted a more mellow set of lights than the 4x4ft LED tubes in the overhead recess and partly because I found it really annoying having to walk around to the other side of the kitchen in the dark to turn the lights on.

I didn't actually plan how long a light strip I needed for the kitchen, so it turned out the 5m strip of 2700K high CRI (supposedly) wasn't enough. Got around that by cutting the strips into their 3 LED units and spacing them apart on the under counter lights (alu strip from a closet door rail, believe it or not). Was super tedious wiring them all together.


light strips for the overhead light


dimmers (one for under counter lights, one for overhead) and 2nd power supply. The first one lasted an hour as it was a 24W unit with a 60W sticker on it. That'll teach me.


under counter strips with some diffuser plastic (bulk trash find) as a cover, mounted on stand offs made from a piece of small diameter metal pipe (possibly from a toilet roll holder)


dim shot of the overhead light so you can see where the strips are


bright shot, I like the light colour. You can also see the new fan that I installed. Running the wire for that was not fun and required machining some adapters so I could use my socket extensions to hole saw a hole in the side of the box between the light recess and fan hole.


one side of the kitchen


and the other


and some lights under the island more for fun than anything. Makes a nice "don't walk into the dishwasher" light for the nights.


now onto the next project, a new work bench

Yesterday was pretty busy for me but i made the effort to get something done on the little Niva. I finally made the special tool to adjust the valves couple of days ago so its time to button up the engine, i started with washing the front of the engine to remove most of that baked on oil and grease, i used some gasoline and a brash, this is the dirtiest engine i've had to clean, then i focused on the valve cover, its rusty, also has couple of scar marks but i don't have time to look for a better one so i'll fix it. first i check it for straightness then i sended it down and prime it with zink pramer. Then i looked thru my old paint, and found an old white paint, i mix it with some flat black till i got close to the original color, i want it to match the air cleaner and accessory pulleys, from the factory they all are gray i spray it at very low pressure so i can live that imperfect look to match the factory finish, then i focused on webasto heater i fill it up with coolant, with diesel, fited a battery and connect the exhaust it fires up started to sound like a jet engine but its seems to shut off, from experience it hits some safety i'll need to figure out how to connect it with a diagnostic cable, it can't never be easy.

Today I tried to make a slinky and failed miserably. Any one care to reach in and turn off the feed for me?

I got some work done on my jumbo angle plate. I plan on fly cutting it and stuff tomorrow. I hope that I don't screw it up, its not too far from square after all of the welding. The key is to tack the hell out of it before you go to town with all the welding. 154734770723091b2fb8e6248c6099d77fc46b015f480ff4ceacec1f98ed171a0b1fb6aecafafffc6f4550c4d1e0b0...jpg 15473477204829d85ee3793fd62220eef6f48203a2f5c45e5eaefcc1cbae4399ce0e58bfc159d0e4089b022c3446ea...jpg

I am really happy/surprised how well my jumbo angle plate turned out. I had my doubts when I had to put a .004 shim under the angle plate that my son borrowed from his work.

I'm making a couple computer desks. To attach the top to the end case, I'm using T-nuts.
The T-nuts will be attached to the top of the table top and bases will bolt on from inside.
I needed to counter sink the T-nuts so they don't make a bump on the Formica I'll cover the tops with.

I usually cut the countersink with a Forstner bit in my drill press.
But, the tops are fairly big and very heavy, making it very difficult to support level on the drill press.
And, the process was more difficult because I'd have to approach the holes from two different set-ups because of clearance of the drill press pole.

So, I came up with an alternative method. I made a template and used a router with a collar to cut the countersinks.

IMG_1242.JPG

The countersinks came out well.
A 7/8" template hole produced a 3/4" countersink with a 1/2" straight bit.

IMG_1247.JPG

The next puzzle (I've always struggled with this) was to put the hole in the center of the countersink.
With a forstner bit, it makes a dimple in the middle, but I've never been able to drill a hole exactly in the center of such a place. The drill always drifts a little off center, even with a drill press.
Routed countersinks don't make a center mark (not that it would do any good).

So, I made this drill guide to center the holes with a bit of 1.25" aluminum rod.
I can drill the hole with a hand drill.

IMG_1248.JPG

It worked like a charm and the holes are right in the center.
I can't believe I didn't think of this years ago.
This little thing will get used a lot and will have a place in my fixture drawer.

Today i made the effort to do some more body work on the little 4X4, i did manage to apply couple more coats and send them back, i've had to use lot more hardener because is so cold, and i did managed to empty out the can of body filler, so tomorrow i'll need to buy some more body filler at least the trunk lid is close to being finished with body filler stage.

Made this bracket to mount a pair of driving lights on the bike.
Started out with a piece of 4x4x1/2 aluminum angle, after some whittling found the bracket inside. The straps are 3/4 aluminum.
Powder coated them with matt black but they look pretty shinny in this photo. IMG_4233.jpg

Clamped in place. The finish matched pretty well.

Lights mounted.

Messing around with cutting oil no spill container for fun.
This is my take on the tuna can style container. It’s a can that mushrooms came in, I removed the inner lip, machined a piece of delrin out of my junk pile to fit and hold a piece of 1/2” PVC pipe. I used 5 minute epoxy to bond the whole thing together.

Like I need more oil containers

I like that idea jdedmon. I need a few of those too.
Might have to give it a go this weekend since I will probably snow bound if the weatherman can be trusted with his prediction of 6 to 8 inches of new snow.
