mandrel-bends

We've sent out some samples to a few of our manifold builder customers. I was hoping to get some feedback before we formally release them. We are still trying to decide what the ideal leg lengths for the fittings would be. So far the most popular leg length requested is 1-2" of material per side, but the longer the leg lengths the more expensive the fitting as its taking more material. I think we may settle for a median 1.5" per side, as we are only adding 3" (about $2.00 in material) to each bend.

not to thread jack adam, but i'm getting into the pipe elbow market soon too. i posted a sample a while back and am getting my first batch either tomorrow or next week. i have to crunch some #'s still, but i should be able to beat ace's midnight special price. like you said though, this is a completely different market and i think something like this is long overdue. i'm sure they will sell well for you!

Personally, a to me a 1" leg would not be useful.

Here is the thing- the legs need to be long enough to "replace" what would have been a straight section. So with 1" legs, any straight section of runner longer than 2" would still need a straight piece welded in- it's just be a shorter piece. That doesn't save any work.

I would say the average length of a straight section on my manifolds is around 60mm, or just over 2", so 1.5" legs would eliminate the majority of straight pieces from the manifolds- I have a couple designs that have the odd 90mm'ish straigh sectio, so I would still need small straight bits for those, but most of them are 40-60mm, so 1.5" legs would be good.

So I think 1.5" would be good. 2" legs would just create a lot of short scrap pieces.

1.5" is what I'm thinking also. PM me your address and I'll send you a few samples.

Before you sell the first one, or whoever gets the samples.
Would you mind sawing the curve apart at several spots and putting a digi-caliper on the wall thickness at several angles. Prolly go down a couple hundreths - no biggie. I just wanna know.

Also, what finished edge are you going to be selling to we enthusiasts? If you are planning on giving us a groove AND If you've not picked the tooling to do so, Id love to see a 60* bevel with a 1/16" landing on it.
Or am I the only one that cares?

I'll have to bend more to measure one, but it will be similiar to existing pipe bends. I've got a sch 40 1.5 bend here that when cut at 45 degrees which is 0.132 outside and 0.174 inside. 0.132/0.174 ~ 25% material transference .. Sounds about right for the material and radius. (1.90" OD on a 2.25" radius). Actually since ours is an even tighter radius, I would expect maybe another 5% of transference.

i think ill be picking up a few 180's off of you guys soon
