Really nice job on the Spiders Max. Looking forward to the riser for the steady rest and that long threaded rod sounds interesting...

[@swanvalleymachineshop]

Thanks 👍

[@mikemarriam]

Interesting project. Thanks for sharing. Might be time to round up a riser for that Bridgeport.

[@swanvalleymachineshop]

I have thought about it but the big mill will be running soon . Cheers 👍

[@geoffmathieson2643]

I've got an Archer No 1 I've been procrastinating about repairing for 5 years. I feel much better now, thanks Max.

[@swanvalleymachineshop]

Lol ! I still have to make the new clutch plate !!! 👍

[@seamusbolton215]

When I was young I worked with a guy, who on his very first day on the job had his arm broke by narrow bar hanging out the back of the headstock. He was standing to the left of the supervisor who was demonstrating how to use the lathe and change the speeds and the supervisor accidently left the machine on top speed after his demonstration and when he started it up the centripetal force bent the bar and it broke my friends arm !! Thanks again for your video's, I always manage to pick up one or two little nuggets of knowledge

[@swanvalleymachineshop]

Ooooh , that would have been a shock . Thanks 👍

[@TheAyrCaveShop]

G'day Max, Nice finish to the spider projects, simple and clean. Thanks for mentioning your leaving the adjusting bolts out when not in use. I'm not a safety drum beater, but we had a local tech lose an arm getting hung-up on a drive coupling with studs sticking out, quite similar arrangement. Cheers....ATB...

Thanks Max for another bang good project. Especially appreciate the set-up tips and tricks …… like counting revolutions on the indexer by bumping into your hand, various ways to center a round bar for drilling, how to neutrally snug up a bar in the spider and how to save time walking around the shop (having duplicate tools at each station 😉). Such a pleasure watching you work efficiently in your shop. 👍👍😎👍👍 Cheers

I’ve got a 10” riser on my Bridgeport to alleviate the clearance problem with tools and the big work I do. That leads to the problem of needing s second Bridgeport for the small milling I’m trying to do. Isn’t this a wonderful business to be in! Love your video’s, keep educating us.

[@swanvalleymachineshop]

Thanks . The big Stanko mill will be running soon , for the taller & larger jobs . 👍

Hi Max I really enjoyed watching the Centre Lathe Spiders being made, they look factory produced, it is amazing to see how thick the door was that you opened up, they do not make them like that anymore. Once again I thought I heard the HBM whisper “I could have done that, if you give me a chance.” Anyway, thank for sharing your years of experience with the world, everything you do is with thought of all the in’s and out’s and consequences for each job, I really like to see the job quality of each part you produce, and your shop is really starting to look great.

[@swanvalleymachineshop]

Thanks . Every job that gets done is one step closer to working on the HBM ! 👍

[@hmw-ms3tx]

They turned out really well Max. Even got the holes in line with each other unlike some guy I know. The miles walking around for tools comment, I couldn't agree more. For me it is Allen keys. I keep meaning to buy several sets of metric and imperial but haven't done it yet. I don't know how you survive without McMaster-Carr. I'm ordering from them every week. Ken

[@swanvalleymachineshop]

Lol , Just lucky to jag the centre that close by using a scale ! Don't even get me started on Allen keys , esp 4mm ones . 👍

[@dutchgray86]

Got a couple of those Archer tapping chucks somewhere, not sure I have ever actually used them, got several different types of tapping chuck and a few of the self reversing type as well, probably too many different options.

[@swanvalleymachineshop]

Handy to have if there are multiple holes to tap . 👍

[@outsidescrewball]

Nice video and build

[@swanvalleymachineshop]

Thanks Chuck 👍

[@johnturner3301]

Us gunsmiths use these quite a lot for barrel work as we center the barrel both ends ( clocked to the bore ) a tip I would make is when drilling the bolt holes do a 3 and 4 pattern , because you can bet the next long job will be 6 sided. And if turning work that is already finished to bright then recess those bolts and fit some copper pads .great prodject keep them coming.

[@swanvalleymachineshop]

Thanks . If i make one for the small lathe i will do the 3 & 4 holes . Cheers 👍

[@MyLilMule]

Almost have to wonder why most lathes don't have spider's built into the spindle.

[@swanvalleymachineshop]

Not sure on that one . The only ones that i have used , that had one as standard were turret & capstan lathes . 👍

[@624Dudley]

As others have said, I always learn something new. I don’t think I’ve ever seen a tapping chuck before - apparently it’s mainly an adjustable torque limiter. That suggests it would take a bit of practice to get the adjustment right for each size of tap 🤔. Thanks Max

[@swanvalleymachineshop]

Thanks . One reason i like to get the feel of the tap on the first hole . 👍

[@BundyBearsShed]

I hadn't thought to open up the hole in the gear cover. Looks like another job on the list.

Nice outcome on both of them Max, and a few different set ups to achieve that outcome overall which is always interesting to see which way you choose to tackle things. The radius on both of them looks flash as a rat with a gold tooth. 😜😂 Nice to have a mid week video which I wasn’t expecting, - a bit like winning my ticket price back on the powerball always a surprise and always welcomed.

[@melgross]

Max, you’re worse than I am and I thought I was the worst. I’ve had stuff sitting for almost two decades before I fixed them, but four decades, well, you get the star for that. I’ve got Jacobs tap chucks that work the way. Funny, I almost never use my tapping head. Too much bother.

[@swanvalleymachineshop]

Thanks . I only use it for multiple holes ! 👍

[@frankerceg4349]

Thank you Max!

[@swanvalleymachineshop]

[@907jl]

Nice work on the spiders Max, they look great. Very useful lathe accessory. Do you think there would be any value to spot facing the set bolt holes, so that you have the option of snugging up a jam nut on the set bolts? Not a nit pick, just thinking out loud.

[@swanvalleymachineshop]

No , i have not had them come loose on other spiders before . But , thinking about it . It would be a good idea if you were doing multiple parts & then only have to loosen 2 bolts to change the part . Cheers 👍

[@paulcurtis2779]

Nice job. . Looks really good. . Glad it will help you be safe.

[@rogerwilliams2902]

Lovely video again. My DSG 13/30 has a spider as part of the spindle , with a shoulder to which a graduated movable collar slides against , something to do with multiple start threads !. Wouldnt have a clue how to use it though unfortunately .

[@swanvalleymachineshop]

No worries . I have never come across that set up before . Trust DSG ! Cheers 👍

[@alansmith5690]

Max, you could still get replacement clutch plates for Archer tapping heads as of three or four years ago. Of course the pandemic has likely changed all that. The material that Archer used was apparently vulcanite which I believe is derived from rubber.

[@swanvalleymachineshop]

Thanks for that . 👍

[@paulrayner4514]

cheers Max. See you on the next one!

Found a few old spiders still attached with grim.. There are many attachments for a lathe. There time savers.

[@swanvalleymachineshop]

Thanks . I have lots of cooked spiders here , from our heat wave ! 👍

[@muddlersworkshop]

Just a question is 4 bolts better than 3. if I was to make one, I would have used 3 bolts but I don't know where I get that from.

[@TheAyrCaveShop]

Much easier to center the work with 4 points, with 3 points two angles or planes are effected with each adjustment. I learned it the hard way. Great question..

[@swanvalleymachineshop]

4 bolts . 👍

[@alanremington8500]

Nice one !! ...and lengthy !! I like it.

[@swanvalleymachineshop]

No worries 👍

[@windrk_6754]

On my Taiwan dividing head you can disengage the worm & spin the head freely, & there are also 24 index holes directly on the faceplate w/ an index pin - if your head had this feature it might save some handle twisting?? Also, wondering if it would be beneficial to reduce the speed ramp-up time on your VFD - I was watching to see if the tap would disengage before it stopped at the bottom of the hole! & this speeds things up as well.. I have not tried power tapping in my mill yet, it only has permanently engaged fine feed on the quill - but I have a couple of tapping- head-like devices sitting on the shelf waiting for cleanup/fixing, to eventually try. Thanks for sharing this interesting work!

[@swanvalleymachineshop]

My indexing head can disengage as well . Also has 2 rings to direct index from . The ramp time could be shortened . The machine will be wired back to 3 phase soon .👍

[@johnbloomfield5705]

A really nice job of boring and fitting the spiders to the lathe spindles but had you thought of mounting a 3 jaw chuck on the rear end of the spindle instead? That's what I have done on both my lathes since I do long bar / tube (hydraulic cylinders and rods) work daily. The boss of the 'top hat' shaped chuck backplate is split length ways and for half the circumference just behind the chuck mounting flange with a single clamping bolt (two on the medium and three on the largest lathe which has a 3.25" spindle bore) which holds the assembly in place.. Yes, it is a larger and more more expensive solution than your spiders since one has to source a 3 jaw chuck and reduce most of a piece of 10" diameter barstock to swarf but much more convenient in use.

[@swanvalleymachineshop]

Thanks . If i was doing long stuff all the time , i would probably go that way . I have seen that set up on the large Oil Field lathes . Cheers 👍

[@willemvantsant5105]

Hi Max, the Bulldog tapping chuck might be a bit of mission to repair finding suitable friction material. They probably used asbestos interwoven with bronze fibres, the ears must be robust enough to withstand the torque. When you said you were going to make a riser block I thought it was for the BP, then you continued to say it was for the fixed steady Just a question, can you buy 1 7/8 threaded rod to save all the work in making it. In the refinery we used B7 threaded rod and just cut to length.

[@swanvalleymachineshop]

I might try some industrial brake friction material from the brake reline company we use . The cost is $ 300 for B7 1 7/8 , i will make my own ! I only need a few bits 300 long , but i will screw cut the entire bar . 👍

[@WireWeHere]

So because one hand always right the other's left doing the grunt work?

[@swanvalleymachineshop]

Maybe ! 👍

[@warrenjones744]

What is the matter with chucking your tap (not real tight or not real loose) in a Jacobs key style drill chuck Max. That's how we do it out here in the woods when there is no room for the tap head or lack of a dedicated driver (which are fairly easy to make if need be). Curious to your thoughts on that. Of course a nice sharp tap is necessary. I hate dull taps and set them aside.

[@swanvalleymachineshop]

I have been doing that for ages , mostly with smaller taps because it's quicker ! Tapping head grips the taps properly so they don't slip , i am not big on over tightening a drill chuck to hold a tap . Esp with more than one hole to do . Cheers 👍

[@bobvines00]

Max, what kind of (speed?) control(s) do you have on your Bridgeport? When you were using the tapping head, it looked like the control tapped, slowed down, and reversed by itself -- without you having to push buttons or turn cranks. Also, as an example of how much walking around in a Shop to do a job, when I was working (about 15-20 years ago now in this example), we did a "5S" cleanup of a jet engine assembly shop. A coworker and I were tasked to follow one Artisan around for me to write down everything he did (& why) and my coworker had a measuring device to measure how far the Artisan had to walk around to gather parts, tools, fixtures, consumables, etc., to perform his task. To make a long story a bit shorter, the Artisan literally walked around about half a mile before he could start & complete his task -- and the assembly shop was no larger than your new workshop! We arranged for him to have everything within arm's reach to perform his task and a half-day task turned into less than an hour. The same was done for every Artisan in the assembly shop and their turn-around-time on assemblies dropped to less than about 1/4th of what it had been. Other teams worked with all other shops in the jet engine building and did the same, greatly reducing the time it took to repair an engine and rebuild it, therefore greatly increasing the number of engines needed by the fleet.

[@swanvalleymachineshop]

Thanks . The Bridgeport has a VFD with an auto reverse function when the stop button is pushed . It takes the spindle a while to wind down when shut off , but that is the way i have it programmed . I do not like instant braking with the VFD , not good for the machine . 👍

[@TedRoza]

Gday Max. Excellent video with the spiders overal. A question if that's ok. 1. With the tapping jig when you stripped it down, why didn't you replace the MT2 shaft & make an R8 shaft in it's place, then you would have the extra room required.

[@swanvalleymachineshop]

Then it would not fit the lathe . 👍

[@WilliamChitham]

That morse adaptor does steal a lot of height, is there room in the R8 to push the taper up higher?

[@swanvalleymachineshop]

I would have to make a custom adapter as i do not want to fit a riser to that mill . 👍

[@huibhoogendoorn503]

Hi Max, thanks for shering. A quistion about the weight on the Bridgeport table from the dividinghead, isn"t this to heavy? and deform the table?

[@swanvalleymachineshop]

Yes , it is always a concern . I try & leave it sitting over the knee when not in use . Trouble is , 99% of my recent and ongoing work involves the indexing head . I will buy a smaller one one day for that mill . 👍

a mobile safety screen ? so on lookers don't walk into the spinning bar ?

What is the black switch you use to turn on the bridgeport and what power do you have coming into the shop? Great videos.

[@injuredplea]

Not a machinist so I'm curious about the risk of damaging the thread when reversing the spindle. Does the autofeed ensure that the tap correctly re-engages with the thread when reversing the feed? Thanks

Not supposed to go all the way through . Normally picks the thread pitch back up again with no worries with a gentle feel . 👍
