Ship660, what size and how long are your bars? 32K is a reasonably price. Just to rent the Climax BB 5000 is over 2K per week and that is not including a bore welder. I was talking with a guy who has a couple Climax setups and has done some high profile jobs, he said he doubted Climax would deduct the rental cost from a purchase as he has tried in the past. One would think if they got you on the hook it would be a long term thing, not worried about 4 or 5 K when they know you will be coming back to expand your setup.
Thanks for your input and the others that have added in too, has been a big help.
I know when I had the opportunity to run the 5000 it was a sweet machine, but not cheap, not sure my bank will want to take that risk on me.
I will be curious as to when I get some quotes and able to compare the different ones.

I use a B&D unit EV-2500-s type, have a look on the net for the different set ups, most manufactures have got demo videos.
Again like Nige has pointed out you need to know what unit will suit your job requirements.

Just had a look on the Bore Repair System site and the setup I've got is now called BRS2

ship660 · Apr 2, 2016

I have 3 bars. a 6' x1.75, 6'x1.25, and 4'x7/8. The 6' ones use 1/2 tool bits and the 4' uses 3/8 tool bits. The set is a BRS4.

Have alook at the Sir Meccanica and ELSA machines aswell

KWD thanks for the info, I will check them out as well.

I'm in Nevada and I've been running a Climax for five years. If you are under six inch bores the electric drive is great. If you are over six inch you will burn up a drive motor every few years. I've burned up two in that time. Part of it I found out later was because I was not running a heavy enough extension cord. As dumb as that sounds, if your drawing a lot of amps it does make a difference. I also run Boretech welders. I've had good luck with the older one but it doesn't have all the extra features. The newer one I run has some great weld buildup programs. They are not cheap but they do work good. I am set up with 2 1/4" bars up to eight foot and I have the reducers to run 1 1/4" bars which are also up to eight foot. Oddly enough the 1 1/4" bars are from an old B&D setup that we retired about the time I started. One thing to remember about boring bars is to make sure you get them drilled with the tool spacing that you want up front. The majority of our bars have 4" tool hole spacing. A couple are 6" and there are a few that are custom. This will save you from trying to get your bearing spacing right and still have some feed travel.

Truckdoctor, thanks for all the great information in your post about your setup, will add it to the information I have gathered so far. Waiting for quotes back from the manufacturers. I'm thinking buying a new truck is easier then this.

Of course it is, there aren't so many options ......

StanRUS · Apr 7, 2016

Waiting for quotes, will what happened to the old fashioned telephone response with pricing? I did actually get prices within 10 minutes from 1 US manufacture and 1 South American manufacture via a phone call.

@TruckDoc
So do you purchase replacement Milwaukee motors from C-max? You can save over 50% by purchasing from a Milwaukee jobber and modifying the motor yourself, doesn't even require disassembly.
The new current Eibenstock reversible motor specs 8-to-160 revs per minute, what machining issue would that cause based upon your real world practical experiences?

Williams Marine · Apr 7, 2016

Climax BB5000
-Rotational drive
-Axial feed
-12" leadscrew
-Tool Kit
-(2) single arm bearing mounts
-(2) universal bearing mounts
-Set up cones
-Electric Motor and control
-3.6cu hydraulic motor

New $23,514 US, used $18,800 US

6ft bar $1329 US, (did not say but am assuming this is a 1-1/4 bar)
Would still need to add a bore welder.

I think I'm going to go look at new service trucks as Nige said "not so many options"

Nige · Apr 7, 2016

When I said earlier that going for a hydraulic-drive Climax machine was based on experience, it seems that truckdoctor in Nevada had exactly the same experience as we had with previous Climax electric drive borers.

StanRUS · Apr 8, 2016

WM, 4-14ET York with Borewelder will cost $21thou not including boring bars.
You priced a 3.6cu" hydra motor, can you assemble your own hydraulic power pack say 5Hp electric motor 6gpm @ 1200psi? If not 5Hp HPP can be purchased from York way cheaper than C-Max.
Mounting Arms: 1" plate doesn't matter A36, grade50 etc steel has the same modulus of elasticity without increasing thickness rigidity will be the same. U can hand cut to shape with oxy-ac torch, hand drill and tap the mounting holes, specs are in C-Max pdf file specifications.
Boring Bars, hard chromed cylinder rod shafting buy 22ft length, straighten with heat opposite side cold water. Keyway 3/8" machined with Bridgeport type knee-mill. Tool Bit Slots: used round 12mm tool bit holders, purchase from the Italians if you can't find in the US. Why round, just requires drilling a 12mm hole versus drilling-broaching.

Hydraulic Motors, 20thou hours typical life cost $280.00ea jobber price. SAE#2 mounting with 1" dia shaft 1/4" drive key.

Thanks for that information StanRUS.
All the input has helped, much farther along in the process then my first post.
Thanks to all for your insight, opinions and wisdom.

StanRus, hard chromed rod is dificult to doing a keyway, you take a solid carbide endmill?

Do you have a web link for C-Max?

EDIT: never mind I just realized that was an abbreviation for Climax. I'm not too hot this morning. lol

Pretty cloudy on the South coast today too, more coffee!

StanRUS · Apr 8, 2016

Yep, solid carbide roughing end mill set to final depth of cut.

We purchase our motors from Climax only because our purchasing department does not have an imagination. I don't know anything about the other motor that you mentioned. I though of adapting a MECO four speed electric motor to the Climax driver. The MECO is normally used for core drilling concrete and I think you can swing a 20" core drill bit with them in low. I haven't been around those since 94 so I haven't kept track of if they are still in business. The four speed gear box would help with setting the bar speed without lowering the motor speed. When I worked in concrete sawing and demolition we had the same problems with the Milwaukee's there as with line boring. The MECO was more serviceable and didn't end the abuse.

it is reversible motor?
