I have very much enjoyed the series. I noticed you haven't posted in over a year. I hope you are doing well and wish you the best going forward. If you ever have the opportunity to finish the project i am sure i speak for others in saying we would be blessed with more videos from you. However your health and happiness are more important and wish you the best in whatever you do.
Excellent work. I made one of these. The GHT design is very flexible. Mine uses a straight shank ER25 collet holder.
I have loved this series so far. I really appreciate your pace, taking the time for explanation when needed, glossing over when not, showing an awareness of your audience. Hoping you have an opportunity to complete and document the rest. Thank you!
I do not have a myford lathe but would still like too see the die filer from Hemingway Kits. For Lathes
So glad I found this series. Looking forward to watching it to conclusion and will gladly subscribe. 👏👏👍😀
I just binge watched all 11 parts you have so far up. Hoping we get some more content from you coming up! I appreciate your candor working through issues you encounter. Keep the videos coming and I'll definitely watch!
Nice series, but what's with all those "thee's?"
10 years ago I was given the kit with missing components. Spindle blank was missing. I made the spindle out of 4340 steel. I deviated from blueprints. My spindle is a little bit larger, bored for MT 3 taper, as well with the special taper for 6K collets. Spindle nose is threaded 1 1/2” 8 TPI to match my South Bend lathe chucks. This dividing head is now a very useful tool in my workshop. Modification for lathe 6K collets is extremely useful. Original blueprint was talking about a variant for If I recall, 3C collets.
I have been thinking about the best spindle configuration myself. I do have a set of 3C collets for my small bore South Bend lathe (Yet another project!) so I might make a second spindle to take these. Not convinced by the parallel bore method but will finish the project “as is” and see how it works before trying other things. Thanks for watching!
Very well produced video (and reminding me of the steps followed when making one of these decades ago). Machining cast iron is a very dirty process and best not to use compressed air anywhere near it. Also, recommend covering lathe bed etc with paper to prevent some of the chips and grit becoming a grinding paste. Machining cast iron is the fastest way to cause wear in sliding surfaces.
Really good advice. I am guilty of both using air and being lax with covering ways. I am, however, very careful with subsequent tear downs and clean up. It is also worth trying to do all of the cast iron work at the same time to minimise the number of times you need to sort out the mess!
Do you have the independant tailstock/footstock? I think it's sold as part of the additional milling setup. I have the footstock casting I'm going to machine to use with a 5C indexer I have I think.
No, I only bought the main unit. The projects I have in mind will predominantly be short projection so I didn’t think it would be worth it. I can always add it on at a later date if necessary.
Excellent channel, terrific footage and work.
Thank you for the kind words. Another house move has delayed progress for now but more to come!
Beautiful work. You make this op look easy. It’s not.
Thank you!
Really nice project. I bet you enjoyed doing that
Thank you. Thoroughly enjoyable project all round so far. No surprises yet!
I just found your build of this piece of Thomas history as presented by Hemingway kits. I watched your latest part 11 I believe where you referenced a later video (part 12 maybe) but I don't seem to be able to find it. Have you done it yet and if so where can I find it. Thanks for the series. There's parts of it if like to use in a modification of a Spindexer to incorporate a plate type index such as you've built here. Thanks for the videos. Regards from Canada's banana belt. 🤞🇨🇦🍌🥋🇺🇦🕊️🇬🇧👍
Part 12 is not yet complete. For various reasons the whole project has slowed down I’m afraid but certainly hasn’t been shelved. I should be able to make good progress in the summer. One of the reasons I really like the Thomas designs is the wealth of ideas to incorporate into projects of my own. Thanks for watching the series so far.
@@DrillsTapsDies thanks for responding. I can wait. My project's been on the slow churn for a few years.
You mentioned a couple of episodes ago the possibility of describing the construction of the Hemmingway filing machine, YES PLEASE !
I'm just starting the same kit - thank you for this great guide to other ways of working it! Here's a newbie question for you. After surfacing the first face, you mount to an angle block and do the base. Why not turn it over, face the opposite end (other end of the spindle bore) and then hold in the vice to do the base? Asked by a guy who doesn't have a decent angle plate but does have a good vise.
Thanks for watching. I think the primary reason I went for the base after the first face is that is the order Thomas suggests in his book! This makes sense on the lathe as the face being machined is at 90degrees to the mounting surface on the boring table. On the mill though, it would have made more sense for me to flip the part and bring the other face parallel while I had all of the clamps to hand. In my case I would still use the angle plate to deck the base. It allows almost all of the machined surfaces to be clamped against the plate. Where as my vice jaws would only grip the bottom (top?) 1” of the spindle housing. I also don’t trust my vice to guarantee squareness when holding something like this! I think if you find some way of providing secondary support with jacks (I should have done this on the angle plate too) and checking square, any technique that safely results in a correctly square and dimensioned part will be okay.
@@DrillsTapsDies Thanks - that makes sense. For practice I have a couple of angle plate castings to bring into true. I'm certain those will debug much of the process!
1000 % agreement Time 12:08
Looking forward to the next video. Did you decide whether to make/film the die filer?
Thank you. Yes I think the die filer is something I will be taking on. Time in the workshop is limited at the moment so I can’t say when though! Thanks for watching.
Great Stuff
Thank you!
Can’t wait to see the completed dividing head. Love each one of your really excellent videos❤
I have completed about about 75% of the parts so the end is in sight!
Nice work. We love our VDH, it's an absolutely fantastic piece of equipment!
I'm looking forward to trying mine out! Thanks for watching.
Great to see another progress video 👍🏼
Thanks for watching!
Ah, great to see you back...you've been missed!
Thank you very much. Still more to come.
Enviable outcomes! Looking forward to the next. 👍
Thank you!
Nice video. Flowed well. Great workmanship as always.
Thank you. It is good to be back at it!
@@DrillsTapsDies Good to see another of your videos. You are good at it.
The odd legged dividers you used to scribe the round stock in the lathe? I couldn't quite make that out, have you a video on making those?
I don't I'm afraid. Most of the major brands offer them for not much money. They come with a scribe on one leg and then either with a step like mine, or often with a finger like an external calliper on the other. I think mine are a copy of a Moore and Wright design.
You are welcome!!! Eventually I have to START on mine. Thanks for blazing ahead! I will doubtless use this as a reference.
Starting is often the hardest. I hope you find the videos useful. A small word of caution; I won't know how successful my chosen techniques have been until the project is complete. If in any doubt, follow GHTs 'words and music'!
Not a great deal new to see here I'm afraid, most of this is going over the same techniques as used in the simple plunger assembly. This is really here for completeness only. Still, it feels good to be eventually pressing on with the project. Thanks for watching!
Where is the last part number 11 ?
There has been a longer delay than expected to complete the next part. Machining and filming is done so hopefully I can get it edited and uploaded for next weekend!
I really enjoyed this video. I built the original G. H. Thomas VDH 40+ years ago and watching you work brought back MANY pleasant memories. In my opinion, the finished condition of the spindle thrust faces and spindle bore as presented in the video will cause problems and shorten the useful life of this tool considerably. However, I believe these issues can be corrected with the machinery you have and the investment of a couple of hours at most. Firstly, the the spindle bore should be lapped. This will improve the both the parallelism and finish of the bore and the effective bearing surface. The spindle should be lapped for the same reasons. Additionally the technique used to face the 2 spindle bore thrust faces virtually insures a lack of parallelism and lack of squareness to the bore. Add in the poor bearing surfaces and all your other good work will be for not. I suggest that you use a ring lap to finish the spindle bearing surface to a VERY good fit in the lapped (use a real lap, not sand paper on a stick) bore in the casting. Do all of the turning, threading and lapping of the spindle a ONE SETTING. Without moving the spindle in the lathe, mount the casting on it and secure it with the split cotter. Support the outboard end with your best dead center lubricated with white lead. Run the lathe at a Very Slow speed and at one setting, face both of the thrust faces to removed all traces of the milling operation. The banjo mount boss can also be turned at this setting to improve any finish or dimension issues. Upon assembly, the spindle will run smoothly, without camming and very little adjustment for a very, very long time. I hope you take these suggestions in the spirit that I offer them. Cheers, F. C.
Thanks for your input. Unfortunately the spindle and bore are already together and any lapping now will only make the fit worse. I will probably blue up the thrust faces and scrape them in if necessary to get them square and parallel but lapping at the point of manufacture would have been a much better idea! As it is the spindle I have made has a rather unpleasant bore so there is always a chance that I will remake this part in the future, in which case I will look back on this advice. Regardless it is good info for anyone looking to build their own. Thanks for watching!
Hi just found your channel & subbed. I have done the sensitive knurling tool by Hemingway kits 8 part series & am on with the large bore steady rest for the Myford 7. Regards. Steve.
Thanks for watching. I’m following your steady rest build with interest. My lathe didn’t come with one so it will be interesting to see how well the Hemingway one works before I shell out for a myford original.
I rather enjoy your high speed footage of machining operations with explanation. Some otherwise very good and knowledgeable TH-cam machinists spend far too much time showing real-time operations and their videos could be much more concise with a bit more editing and still make things just as clear and informative.
Thanks, it is a difficult balance. I try to show the whole process for completeness but, as you say don’t want to bore with unnecessary machining. Thanks for watching.
Have just watched this series for a second time, really well done I have this kit but will probably wait till I can make a ball turner and retraction screw cutter Will you be posting any more of the build?
Thank you very much. I find projects often need other projects to complete them, but that is half the fun! I will definitely be picking this up again as soon as I can; I have a little car project that has spiralled out of control at the moment that I need to complete before I can get back to the dividing head. It is sitting in the corner of my bench as a constant reminder!
For someone who claims not to be a videographer you did an excellent job. Your narration and editing were also very good.
Thank you. I appreciate that.
What type of mill are you using?
It is a generic mini mill. Mine is a Sieg SX2p I believe but all versions are much the same. I would love a similarly sized older machine but they don’t come up for sale often. At least not at the right price!
Good work!
Thank you very much.
For someone who is self confessed “not an engineer “ where did you get the level of skill required to achieve these results, I’ve been in engineering for 52 years and would be delighted with these results well done. 😮
Thank you! I think it really just comes down to time. Someone with experience in professional engineering would produce the parts in a fraction of the time it takes me. I’m sure if I was on a job clock the quality would plummet!
Looking forward to the next video in this series. Good work 👍🏼
Thanks very much!
Love those handles!
Thank you. Definitely not the most efficient way to make a handle but in this case I do think they are worth the effort!
I'm really enjoying this project...I hope you pick it back up again soon!
Thank you very much for the support. I will definitely be picking this up again!
I have a similar casting kit. Thank you for putting this up. I intend to reference your fine work when it's time to start. Very well done. I gasped when I saw the part wiggle during the drilling operation. But you managed well inspite of it.... Whew!!!
Thanks for watching. I hope it is useful even if just to highlight some of the things not to do! Good luck with your build it is certainly an interesting project!
I have just found your channel and binge watched this entire series and all I can say is WOW !! Big fan of Joe Pie and his models, but the work you have managed to do on hobby machines is amazing You have inspired me to get back out into my own shed and crank up the old Colechester Student Many thanks
Thanks very much. I’d love to have the space for a Colchester but the workshop space suffered in the last move so it’s a no go. Thanks for watching!
Moar, I want moar! Came over from Rotary SMP, was just going to watch one ep before sleeping. Ended up watching five. x) Keep up the good work!
... and today I finished the playlist as I woke up. So I basically binged it, with a 9 hr nap in the middle. :)
Thanks for watching! I’m itching to get back to it but other things have taken over at the moment. More to come.
@@DrillsTapsDies I know how it is. I have several project going at the same time, some gets put one ice for a while for one reason or another. Then there is life too that wants a piece of the time pie now and then. <x)
Tell me about it! Pulled the engine and gearbox out of my little car in August to swap out some bearings and it has turned into a total rebuild! Bench is currently covered in the contents of a gearbox and overdrive unit! It was only supposed to take a week!
@@DrillsTapsDies Sorry for laughing out loud right now, but I hear ya. My work area looks like my toolbox exploded and took the parts pile with it. <xD Also, I start a project, partway in, I realize I'm going to need tool X to complete it. I start a rabbit hole of research into which version to buy at the lowest possible price (cheapskate), or look for parts/material to make it yourself. Several weeks later I'm no further along in the original project and have created two more side projects too boot. I swear, the things to do list is a self replicating entity, it keeps increasing in length. <x)
Damn it, I was supposed to sleep after the first video, and I’m now 4 videos deep! <x) Keep up the good content! Subbed. :)
Thanks very much. Apologies for keeping you up!
Super cool! Your use of the boring head as a Radford-style ball turner is clever, I'm stealing that idea. Cheers!
Thanks. I was really lucky that the boring head I had made years ago had almost the perfect dimensions to make it work. There are quite a few examples on here of people who have done similar things so should be plenty of food for thought for you.
Really enjoying your channel 👌
Thank you very much!
