A quick small job.
Wanted to fit a lens onto an astronomical camera (http://www.myastroshop.com.au/guides/gstar/gstar-ex4.htm) for a friend.
My first attempt relied upon the expert who knew all about these cameras (not myastroshop) who told us it was a metric thread and checking it out with my thread gauge it appeared to be a 0.8mm thread which I duly cut.
Hmm, must have cut a taper thread as the lens only screwed in half way before binding.
I dug out an sae gauge that I've never used and double checked the original thread, hmm, it looks like a 32tpi thread also fits.
So I bored a hole and cut the 32tpi thread. Success, it screwed in all the way.
I made a mandrel and screwed it on so I could turn it to size and cut the outside 32tpi thread. (it did have the centre in place when I turned and threaded it)

all screwed together

This is now a wide angle camera.
This was the very first non metric thread I've cut.

After nine months of being without my machines I finally was able to make chips again today in the new shop.

A couple of aluminum spacers for a grab handle for the wife in our Jeep.


After turning to size I put them in the mill vise a machines a radius on one end to firmly seat against the handle.


Completed.


Just need to get a couple of metric fasteners and I can bolt it in the Jeep for the wife.

Next up was a new part for the latch on the toolbox in the back of my Jeep. I have gone through three of the OEM latches and although Mac's has been great to warranty them I would rather have a latch that held up rather than a warranty so I decided to grab some 1045 bar stock and machine a new part for the latch. The original ones are a cast aluminum and just not up to the task.

Turning the major diameter.


After turning the three different diameters into the part I put it in a collet block and machines the void for the connection to the lever.


Now ready to machine the flats on the minor diameter.


Part completed and next to the original broken part.


Completed and assembled for a test fit.

Mike...
Nice job on all the items, but I'm curious.
Is the latch fix a tool box in the Jeep, a Jeep item, or is it an aftermarket tool box?

Bill, the latch is on my Mac's Tie Down's Black Box that is an aftermarket/accessory toolbox that my wife bought me for Father's day last year. It is extremely well built and has some nice features, but I have gone through three of the OEM latches now and even though Mac's has been great to warranty them I want to remedy the issue. They seem to fail at the most inopportune time and I would rather not have to deal with any more failing latches. It is one component inside the latch that fails and being cast aluminum I just don't think it is up to the task and could be improved upon as far as material choices.

Thanks for the comments Bill.

Just completed this VFD control system and getting ready to ship it out, always seems to take longer than I think, but nice that it is done. This is a more basic control system build with controls in two pods. Forward, Stop and Reverse switches are all momentary and interlocked. In this case the control board is mounted in the VFD cabinet, the breakers are for the main power in and two duplex sockets. Separate power is supplied for 12 and 24VDC.

I like that design, nice and simple.

Nice may be simple to some. Yea, I need to learn some of that electronic stuff, Normal contact, and things like that OK, But all this other stuff, I have not got a clue .

Knocked another latch component out for a friend who is having the same issue with his Black Box. Thus will give me two in the field being tested.

Machining the last flat on the minor end.


Two completed and ready to install them into the latch bodies and install in the boxes.

IIRC, small TV lenses are "historically" 1" x 32 TPI. I occasionally designed TV camera based optical systems while at HP. Glad you got it figured out! The entire proliferation of English/metric is frequently irritating, especially when you have to mate unrelated components to each other ... and then if you're an auto buff, you get to deal with Whitworth and maybe even BA. Ah, well ...

Thanks Randy. I will have to check it out. I thought the whole purpose of Tapatalk was to be able to load pictures easier but for some reason all I see on my PC are red X's. On Tapatalk just fine. On garagejournal both Tapatalk (iPhone) and PC are showing the same.

I made a tool for drilling new dowel pin holes on the back of my VW crank. Ended up someone else needed it more than I did as he had a problem with his daily driver. I gave it to him to test and am waiting to see how it worked.

I know there is a commercially available tool out there but I didn't buy all these machines to buy stuff from other people :)

I'll be out with friends / family and they'll be sitting around talking about Game of Thrones, Deck of Cards, or whatever TV show is the rage these days, and all I want to do is scream because if I brought up the latest video from ecdez I would just get blank stares. I don't watch TV except for the odd movie here and there. Although that's not accurate for all my friends, I do have a small group of people I hang out with that enjoys listening to my machining adventures.

That's a good point. I don't watch TV either and have no idea what the newest TV show rage is. None of my friends know who Adam Booth or Clickspring or This Old Tony is. I'm in a world of own over here.

Same here, I don't watch TV except for news, jeopardy, Big Bang, and Madam Secretary..
Otherwise it's volleyball or the shop... And youtube , I like the machinists on there.
I figure life is too short to be sitting there vegging all the time.

Right now, I have a new dog, so all the shop time is off the table until we are fully bonded, and trained. This week is just bonding only, next week I start intense training, trying to get him to where I would like him.
At work, all the young people talk about the shows all day. I don't think they do anything but watch tv.

Haven't watched any TV for at least 5 years. Just eats up too much time. When I do have some downtime, I'll read a book.

I do agree that listening a bunch of people endlessly discuss the latest episode(s) of "whatever" to be about the most boring thing I've ever experienced. I'm much more interested in what people do. Sitting in front of the tube (OK, flatscreen ...call me a dinosaur) is so durn passive!

OK, end of rant.

Started catching up on that growing log pile. Sawing the first log a bearing on the axle supporting the blade wheels started howling, then rumbling. I used cheap Chinese bearing from Princess Auto when I built it. This is the fourth one that piled up. The ones I got today are Japanese. 1 3/4 inch self aligning



Like the other ones the cage broke up, on a couple of them the inside and outside race broke. Caught this one in time.

On the weekend I finally finished my collet closer. It's a simple drawbar/handwheel with a thrust bearing. I had drawn it up a long time ago and the internal threading kept me from starting this project. I guess it took about 3 weeks, plugging away a little bit at a time in the evenings after the kids went to bed.

During the course of this project I really got my new QCTP dialled in. I now have about 10 tools loaded and ready to go.

The hand wheel is an old power steering pump pulley that I machined the belt ribs off. The thrust bearing is from INA. The rest is mostly self explanatory.





The piece I'm most proud of is the bulky piece in the middle. The hand wheel is a press fit, the thrust bearing is a close sliding fit (in case I need to take it off for service / replacement), and the end is threaded M30x2. I also bored most of it out to lighten it. It's 1018 steel. I hit all my dimensions and the surface finish is very smooth! I used indexable carbide for rough cuts, and finished with a nice sharp HSS bit.










For the aluminum sleeve, I machined it for a press fit (about 1.5 thou interference), and heated it up to help it install. Went on really nice and I machined the taper after it was on the tube.


I had a few people over to hang out in the garage over the weekend, and a couple laughed (all in good spirit) that I wouldn't just buy a washer and was making one out of stainless. Once I finished it they definitely agreed it was a nice touch! :p

Hey Mike, thanks. I had thought about knurling the wheel but fear my knurling abilities aren't quite there yet. It is something I can always do a little later, after I've had more practice.

I really like my Grizzly G0709 lathe set up; good variety of quick change tool holders within an easy grasp. One of my other lathes is a Clausing 12 x 24 which usually has a 5C collet chuck mounted. The QC tool holders for it had been setting in a HF tool cart within an easy reach, but not as convenient as the Grizzly set up. The Clausing doesn’t have a back splash on it which leaves some hard to get to places to sweep up swarf on the back side of the lathe.

I “stole” the idea on a roll-around back splash/tool holder from another poster on this site. I couldn’t find the OP’s posting to give them proper credit but will if I eventually find it. Second best activity is reading through old postings on this site!

The frame is 1” square tubing with 1/8” wall thickness. Cut the pieces on a chop saw, welded with a Hobart 190 MIG welder. Sheet metal is 20 gauge galvanized. My Tennsmith shear has a 37” capacity, HF 3-in-one sheet metal machine a 30” press brake and my Diacro brake has a 24” limit. The back splash was made from 4 pieces of sheet metal because of my equipment limitations. Ideally it would be one piece. The lower splash pieces were attached to the tubing with sheet metal screws, as were the vertical panels. Everything was painted with 3 coats of Krylon gray primer/paint.

The tool holder rack is unistrut bolted to the top of the back splash with a couple of aluminum blocks. There’s also an aluminum plate with a series of 1” holes for tail stock tooling bolted to the rack.

All in all it makes for a nice set up. Keeps the chips off the floor on the back side of the lathe, tool holders are right there for quick changes. Oh, nothing special about the dimensions, base on casters is about 1” wider than the lathe. The vertical tubing is between the front and rear casters so it isn’t tippy, though it does have a little wobble back/forth if pushed hard. Maybe a diagonal brace between the base and the vertical tubes in the future.

Wowsers!! The idea of a mobile backsplash is absolutely fantastic! As you say in your last caption, it makes for easy acccess to the back of the lathe for service. Now I've gotta figure if I can do this myself. Thanks for your post.

Found the original concept in POTD, so kudos to Roadie33 for the original idea. Here's the page with Mike's post.

My TPAC Tools lathe DRO came with a sheet steel rack for collet storage. Happened to be 1.10” diameter holes for R-8 mill collets, so not very useful on the lathe. Finally got around to work on mounting the rack to my mill’s DRO arm. Problem is the rack came with 10 holes and with my set of collets run from 1/8” – 7/8” by 1/16”, needed space for a baker’s dozen. On top of that, it’d be nice to have my drill chucks and 20 mm collet with an electronic edge finder handy also.

Solution was to add an extension onto the end of the steel rack. Cut the blank from 1/8” aluminum and laid out the holes with Dykem. I’d never used the center finder attachment on my Shars co-axial indicator to find a center punched hole, so gave that a shot. Long story longer, got there eventually, but will stick with a wiggler in the future. Probably just lack of experience on my part, but I can find a center punched hole a lot quicker with the wiggler than the co-ax.

Drilled and bored the holes to size (1.100”) on the mill. Screwed the extension to the rack and scribed two overlapping collet holes. Those were bored oversized for clearance. Screwed the rack and extension to the DRO arm and loaded it up. It worked, but there was a lot of cantilevered material and weight hanging out there, so it’d bounce up/down very easily.

Made up a bracket pattern to tie the cantilevered end back to the DRO arm out of chipboard. Transferred that pattern to 1/8” aluminum, then band sawed, sanded and bent up the bracket. Everything is bolted up with 8-32, 10-24 and ¼”-20 button head cap screws and nylock nuts. Version 2.0 is rock solid! Next improvement will be a draw bar wrench holder on the existing rack front screw hole. Seems like my draw bar wrench continually vibrates off the table and hits the floor.

Well I couldn't let Bruce have all the fun with tidying quick change tool holders. Seeing his post inspired me to take mine out of the little wooden box I had them hiding in, and mount them on the wall. I used some clear vinyl tubing over the screws to protect the tool holders from being scratched.







I figure I'll probably buy another couple, hence the two unoccupied spaces at the right end. If I end up with many more holders (probably will be the case...), I can mount another strip of pine under or beside the existing one.

Then I got really ambitious and made a bit better use out of the work bench. Nothing fancy, just moved the tool box a bit closer to the lathe and installed a basic shelf above it for the radio. I hope the new empty space to the right doesn't just collect junk.





I hope this is the beginning of a roll to clean up some of the clutter on this side of the garage.

Posted a during construction photo a while back, Here it is in the customers cottage. The top is quarter sawn ash from my sawmill. Had to buy the 2 inch material for the base.
The wings on either end pull out and the top drops down to make the table 7 feet long.

Not much but I finally got something done in the shop. Retro fitting a mid 50s jubilee horn from and old panhead on my 84 shovel head. Still working out some issues but today slotted the stock bracket to allow it to clear the gas petcock. However I could not find my r-8 collects. And I don't have an r-8 collet holder for my er32 collects. But I had an extra R-8 3/8 collets. So I free handed the 1/2 slot.20170814_194833.jpg
