Happy days Tom 👍🏻 nicely done buddy, made the best of an awkward job there, I did hold my breath when you started pressing it in ooer lol Keep warm and safe my friend
My thoughts were along the same thoughts as Steve's, but having the Horz mill up and going will be sweet for the next job like this (@@)! Were finally above 32 dw here in Tx, but another front to hit this weekend 😞. Stay warm, and keep on keeping on, Bear.
The sheppered dog I had years ago absolutely loved the snow. It was great fun. I know i'ts off topic, but still... :) And indeed, the double boring bar was a very good idea.
Nice one Mr Khaos and not bad from you Tom👍👍👍👍👍👍👍👍👍👍 Great idea with the double boring bar Tom, i was holding my breath when you were pressing in the bush in, seemed to be very tight, on camera anyway. You've certainly got incentive now to get the Borer up and running. Great video Tom, bye the way can you keep that snow over there, i hate the stuff when we get it🥶🥶🤣🤣👍👍👍👍 Best wishes Kev (UK)
I will do my best with the snow. It was a tighter press than I would have liked. I did hone out the bore so it would be a smoother slip in on the sides.
Your boring bar looks like it is for negative rake inserts. You can't always use that style in a bore because the clearance angle is negative. On a lathe you can set the cutting edge below center to accomadate the lack of rake. On a boring head it is by nature on center and I think this rubbing caused a lot of your chatter issues.
Hello Tom. It's the shits when you have the right equipment for the job but it's not running yet. I had my HBM in my shop for two years before I was able to use it. Many jobs came and went during that time that the HBM would have been perfect for. I will offer one piece of advice when you do get it up and running. Make yourself a bar (or several, different sizes) that you can mount to the milling spindle. Make it a solid bar (say 2" diameter) and then mount a cutting tool in the end of it (either carbide or HSS) and adjust your size of cut by moving the cutting tool outward using a dial indicator (similar to line boring size adjustments). It sounds clumsy and slow but the increase in rigidity over a boring head with 3/4" or 1" bars allows deep cuts and high feeds that more than make up for the slower adjusting time. I did this for my machine because I had a number of frames to machine that had a 3" hole that was effectively 8" deep. I was able to take interupted cuts that were .200" deep at a .010"/rev feed rate, including through weld buld up. I show this set up in my video th-cam.com/video/Rwyym13cLNo/w-d-xo.html . I think you have seen this video as you left a comment on it. Looking at the job you did in this video I would estimate that on my boring mill with the bar I made I could have bored the welded hole to size in probably less than half an hour. (obviously some of that can be attributed to the greater rigidity of an HBM over a vertical turret mill). I got this advice from HBM guys on Practical Machinist while reading about boring on HBM's. I took the advice and it has worked out fantastic. I think you will really enjoy using your HBM once you get it running. Ken
Hey Ken good to hear from you and thanks for the pointers. I have been acquiring 1 3/4" round bars to make boring bars with. That is the bore size of my tailstock bushing.
Very interesting video Tom. Such a clever and creative idea on the double boring bar. I'm sure your customer will appreciate the hard work. So far we've had mo snow were we live. Great to have a friend like Khaos to keep you company in the workshop. Keep well and warm, both of you. Cheers Nobby
Good job Tom... and Kaos. Yep, it would have been easier on the horizontal boring machine but you nailed it anyway. Pressing the bush in was tough... You could have placed the bush in the snow for an hour to shrink it first, making it easier to press in.
I see you are back to running a kerosene heater. I also noticed a wood burning stove not being used. Have you considered purchasing a Hot Dawg style propane heater and hang it from the ceiling, with a tank outside? I have a 150,000 one that heats my 30x60 with 13 feet high ceilings. Thanks for sharing the video.
I have been using the wood stove. It does a great job of warming up the shop. I use the kerosene heater to take the chill out while the wood stove is getting going.
It sure sounded hard on the mill. My horizontal mill has a 1 1/4 inch boring bar. Do you think that would have worked better? I'm not sure if the table has six inches of travel. I will check that. Good one Tom. Get that horizontal mill working.
Nice fix Tom did you bury that sleeve in the snow overnight? When you ran out of ram I thought it was stuck. Well you got a good workout anyway. Thanks for the video.
I've only seen that doubled up boring bar one other time. I take it the Jet lathe doesn't have enough swing for something like that? At least you have the room for a boring mill, it'll be nice when that is up and running.
Hey Greg. Yeah not enough swing room even with the gap removed it was going to hit the ways. Not to mention it probably would have been pretty scary having all that weight to one side of the chuck out of balance.
G'day Tom. Nice job done, just wondering why you didn't make & fit sleeves in both ends, would have been easier. In the end, everything fitted & should work just fine for the moment
Hey Tom, interesting job and great idea to stiffen the bar. Great to see how you can go outside the box to adapt and overcome. 👍
Thanks Dave. It sure was trying me. 😀
Gday Tom, using the second boring bar for support is a brilliant idea, top jo, cheers
Thanks Matty. It certainly worked pretty well for what I was throwing at it.
Great job Tom , you used what you had and got the job done ! 👍👍
Thanks Shawn.
Happy days Tom 👍🏻 nicely done buddy, made the best of an awkward job there, I did hold my breath when you started pressing it in ooer lol
Keep warm and safe my friend
I think I said a few British cuss words too. 😂
@@hilltopmachineworks2131Good man 😂😊
You got there in the end . Some wild chatter ! Bridgeport would have made short work of it , boring bar & support bearing . Cheers Tom 👍
It was an adventure.
Hello Tom,
Somewhat challenging job I imagine... I think it would be a breeze when the boring mill.
Take care.
Paul,,
Hey Paul. It was a bit taxing. The Boring mill would have made this job so much easier.
Interesting job with some pucker moments. I had one like that a couple of days ago.
Yes indeed. If I drank I would have mixed up a stiff cocktail afterwards. 😂
The boring bar idea is good.
Thanks.
Nice job on a tough piece, I keep a van Norman portable cylinder boring bar for jobs just like that but it’s slow going as well
Thanks Adam. It definitely was taxing that is for sure.

It has not warmed up any so the snow is staying around. Yep we are getting more tonight.
Good job Tom. I am hoping to have a line boring/ welding set-up in the next year. If she lets me.
That will be handy. They can be pretty pricey.
The sheppered dog I had years ago absolutely loved the snow. It was great fun. I know i'ts off topic, but still... :)
And indeed, the double boring bar was a very good idea.
Our other Sheppard dog "Copper" loves the snow. Khaos is more concerned about me throwing his toy than playing in the snow. 😀
Nice one Mr Khaos and not bad from you Tom👍👍👍👍👍👍👍👍👍👍

Thanks Nobby. Snow is sticking around all week.
Clever idea on welding the boring bars! That came out great... Where's the Excello hand wheel?
Thank you. Hand wheel?
That's one big hunk of iron!
I figured you would salivate when you saw it. 😂
@@hilltopmachineworks2131 😁👍

Thanks and Ironically I did have the bush outside for awhile before I pressed it in. Great minds think alike. 👍

Hey there Randy. Yeah it was working my mill harder than I would have liked. Not enough travel on my Y axis for me to do it on my other mill.
Nice fix Tom did you bury that sleeve in the snow overnight? When you ran out of ram I thought it was stuck. Well you got a good workout anyway. Thanks for the video.
Hey Jim. I did stick the sleeve outside for a few hours prior to pressing it in.

@@hilltopmachineworks2131 It does look rather heavy. LOL.
G'day Tom. Nice job done, just wondering why you didn't make & fit sleeves in both ends, would have been easier.
In the end, everything fitted & should work just fine for the moment
Hey Ted. I contemplated going that route. I just was not sure of the durability of a sleeve in another sleeve then the parent material.
Did you weld up the bore? Did you consider boing the original bore out and install an adapter sleeve.
Hey Steve yes I welded up the bore first.
Good evening Tom. just curious, how do you go about pricing up a job like that. Regards Del.
I don't quote for these jobs. I just keep track of the hours I have in it and they are happy to pay because they just want it fixed.
