still searching for 1 1/8" bending solution

[emcoasthvacr]

I'm using a YJ ratchet that works well up to 7/8, but I'm not satisfied using a conduit bender for 1 1/8.

What recommendations would you suggest for those 1 1/8 jobs -- I've been looking at the JD squared solution which will bend up to 2" ?

Thx

They make those:eek: :D

long radius would be even better! wishfull thinking?!

but this guy is no engineer :p

I use ercolina benders every day and they are bomb proof but you need to be bending a lot of pipe to justify even the thought of these.

up to 3/4 we do by hand

7/8 through 1 5/8 we use the 070 medi

2 1/8 and up we use the 030 mega

Hope this helped

Bender works best, long radius, lesser joints, one pipe length, given the luxury of space provided etc.

But if one can afford a bender, the manpower and time to bring it to site, well why not. Its professional that counts. :D

I've heard of benders being mounted to van's/trucks.

The easy solution, technically billable in parts, is elbows.

[emcoasthvacr]

Seriously,

I always prefer to bend & swage so I can both cut down costs and braze only 1 joint -- this cuts down on oxidation in the system (hopefully u guys nitro purge while brazing).

thank you

I don't even want to know what that puppy costs.

The JD Squared will run you about $300, then you have to pay about $150 for each size you want to radius.

Can't you engineer something?

I believe Imperial makes a 1 1/8 bender.

you would think such a highly educated engineer could find a tool he needs.:cool:

all I know is I'm gettin my butt kicked with the conduit bender on 1 1/8 -- you can be perfect and still mess up.

Well it all depends. N2 is expensive you know. If the client can afford it, I'll bring the whole workshop down!

Anyway unless its a major make over, I wouldn't mind investing in one of these benders or two, pay by itself! Haha.

[emcoasthvacr]

u'd think -- I'm not satisfied yet.

I'm equally shocked at the hack work I've seen with the 4 & 5 ton setups both in resi and in commercial -- the contractors that install this garbage should have their license taken away.

rems has a power bender that's awesome for hand power bending, and I would love to have it -- it's too expensive.

a real engineer would design & build his own & call it r & d for
the writeoff. it has to be r & d because they never get it right the first time

[emcoasthvacr]

Back in the day when I had a full-service maintenance machine shop I would machine my own bending shoes.

But your statement is plain silly -- I'd rather pay a few hundred bucks than spend thousands to design & build a solution.

I wouldn't want to take the business risk -- years ago I might have.

So far, the JD Square solution looks like the best.

Before coming to r n d, an engineer would have actually calculated the time and money spend is of course cheaper that buying one off the market. That is why he is called the Engineer. :D :D

I designed and built my own Van storage space with racks bought from IKEA. Total cost : $99.00

If you are fabricating in the field, I would go after the Rems unit as it does not need to be anchored and it is portable.

I have the Imperial Eastman gear bender, and it is difficult to use on soft linesets unless it is anchored.

In addition, unless you are working with hard drawn tubing, I have found that 1 1/8" od linesets are more oval than round... that may cause problems with any bender. I can't get perfect bends on the Eastman unless the shoes are lubricated, and bending opposite the coil direction is dicey at best.

I have not used the Rems unit, but would like to try it.

For now, a Crescent wrench to round the tubing out and an elbow works fine for me.

I tried the conduit bender, and that doesn't work unless you press the tubing against the shoe firmly, and the hold down tang prevents that unless you bend on something like a piece of wood so the hold down does not elevate the bender.

[beachtech]

the world is full of idiots :)

glad to see they stretch from here to florida :D:D:D

[emcoasthvacr]

Can't believe we don't have a 1 1/8 ratchet bender yet -- they all do 7/8.

The REMS power bender is flat out awesome for field & shop work, but it's over $2000 -- too much for field work-- i'd like to have one in a year or two.

I see the application not only in residential & commercial rtu splits but also when you change out a compressor....

It's a lot easier to put the suction line drier outside the unit rather than take the fan assembly out & put it near the compressor -- you can measure the temp drop(or pressure) across the suction drier and replace it with tubing a lot easier -- I've even had tech support say to change out the liquid line filter driers for comp cleanups, instead of using a suction drier -- this is lazy bullchit & I'm shocked to hear it from top manufacturer tech support.

I have never had 1 1/8" lineset tubing round out of the box. I have always had to round it out with a Crescent wrench for the fittings.

Never priced out the power bender... 2k is a lot... should have bought one when the dollar was higher :D
