Hi, I am looking for a bender to make a 3' wide row cover. I don't see one but just double checking?
We dont make a 3' wide hoop bender. This is something you may be able to use an old bicycle tire for.
Hi i have a 40' x 80' green house and part of it collapsed this year and am looking to replace the few bars that got damaged can i make any of these benders work for that size greenhouse
We can only recommend the hoop benders per the size it's made for - ex 12 ft wide bender for 12ft wide greenhouse. These are adjustable a foot either way, but for what your looking to do, I'm not sure that these will work. You can make you 'own' bend using the bender, but I don't know how you'd keep it consistent. If you try, let us know how it goes!
Can the hoop bender be used to form a complete circle or will it only be able to bend tubing into more of a u shape for green house use?
There is some give on the poles, and you could try and bend them a little past the natural bend of the hoop bender, although I think the circle wouldn't look like a nice around circle, you could get something relatively close to it. If you do try it though, let us know how it goes, we'd love to know!
Hi l am looking to construct a green house / high tunnel I like your hoop bender I have most of the hoop lumber I need cover ties
Are you looking for paracord to keep your greenhouse plastic down?
WITH YOUR BENDER IS THERE A WAY TO GET STRAIGHT SIDEWALLS?
There is not a way to get straight sidewalls using the bender.
How many hoops are needed / how far are they spaced? Say if I wanted a 20 x 40' house, how many of the 10' poles would I need to purchase?
We reccomend spacing the hoops 4' apart. Each 20' hoop will require 3 of the 10' top rail poles. If you would like to view all of the required materials to build one of our DIY kits that use the hoop bender you can scroll to the chart of what to buy locally at the bottom of this page. https://www.bootstrapfarmer.com/pages/diy-greenhouse-kits
I’d like to make a 20’ wide hoop house with 2 foot ground posts. Height would need to be 6-8 feet ideally. Which bender would you recommend?
We recommend using the 20' pole bender. The height of this structure would be 10.75' tall.
When will you have more of the 20’ benders in stock?
We expect to have those available in the beginning of March.
I have access to 20 ft 13/8 top rail. Can this be used instead of 2- 10ft and work with the 12ft wide bender.
While we haven't tried this with the hoop bender ourselves, we have had customers that did this without issue.
Hello. Do you have a bender that can bend 1inch Galvanized pipe?
We dont have any greenhouse pole benders for 1" pipe. The closest would be the 10', 12' and 20' benders that accomidate 1 -3/8" pipe. These would generally work but there will be extra space so you may get uneven bends.
What is the inside height of the 6’ wide hoops?
The height would be about 3' tall plus the height of your ground posts.
What’s the roof height of the 12ft wide option? We’re looking at using this to bend 20ft EMT sticks, that’ll ultimately be attached to 3ft vertical walls (goat & pig housing).
If you are building a greenhouse using a 12 ft bender AND ground posts that are 2ft above ground, the height of the hoop house will be about 8ft tall.
I'd need a 24 foot bender
We do not currently offer a 24 ft. bender. Due to the extra support structure needed to brace a hoop house over 20 ft. wide we recommend adding length vs. width to your build to increase available space.
Hi there, any chance you might be making a 4 ft hoop bender in the near future? It's the perfect size for raised garden beds. Thanks!
We're workin on it :) Next gen hoop benders + additional sizes coming later this year.
I have 21 foot top rails can I been two of those to make a 20 foot wide
You would need to cut down one of the 21 foot top rails to 10 feet. Our 20' wide grenhouse pole bender has an angle based on bending 30 feet length of pipe.
I have 20 foot lengths of 1.25 in. galvanize fence tubing. I want to bend these to make a 12 foot hoop for a chicken run. will your 12 bender work on this pipe?
While the 1.25" tubing will fit in the bender, it will wiggle around a lot and you may not get a very nice hoop shape. In order to make a 12 ft wide hoop with our 12' bender we use 1 3/8".
on a 24 foot wide hoop what is the length from foot (base) to foot (base) for the width of plastic film required?
48' wide will work and will leave just a bit extra for sidewall ventilation
Hi, can I use 1” emt conduit for a 20’ greenhouse? And also would you sidewall ventilation crank work with a 20’ greenhouse built with these benders?
Are you looking to use 1" EMT for the hoops for for the roll up sides? 1" EMT may not be strong enough to use for the hoops. It can be used for the roll up sides however it would not fit our hand crank.
Our sidewall ventilation crank would work with a 20' greenhouse no problem if the EMT was 3/4" for the roll up sides.
I have a 34’ wide greenhouse gothic arch I want to duplicate DIY. Do you have hoop benders for that style.
The largest hoop bender we currently have is 24'. Unfortunitly we don't currently have 34' wide.
Can I build a 10' hoop house with the 12' bender?
Or build a 12' hoop house with a 10' bender?
I want to build a 10' and 12' hoop house.
It isn't reccommended to do either one since you will risk having the hoops mishaped. With that said however, using the larger bender to make a smaller hoop house would be the lesser of two evils given that you could potentially squeeze the hoops together a bit when placing them into the ground posts to create a smaller width. Doing it for 1 ft of width difference may be okay but 2ft may be pushing it. I definately wouldn't use a smaller bender to make a larger hoop though.
Can the 6ft bender do 3/4" emt.
Yes it can.
how many 10' 6'' toprails are required to make a single arc for a 24 foot wide greenhouse?
For a 24' wide hoop house we would bend 4 - 10ft long poles to create a single arc.
We received our hoop bender. There is a loop/slot at both ends. Videos show it at only 1 end. It seems like the loop at other side would interfere with bending. Is it defective?
Only the 6ft bender has two slots. One is for if you are using 1/2" pipe and the other is if you are using 3/4". For our other bender sizes we use only 1 size (1 3/8") so only 1 slot is necessary.
My driveway is 10’ wide. I want to build a tunnel for car and grapevine. Can i make it 9’ wide and 12’ tall tunnel with this tool?
You can make that work. It might be little bit of a struggle to get the hoops to slide into the ground posts, but you'll still be able to get it done. A taller tunnel requires taller ground posts, so instead of cutting an 8' pole in half, leave it at 8 ft and put 4 ft down and leave 4 ft up to get a bit higher than the usual.
Do you post to Ireland and what how much would it cost?
Due to operational and logistical issues we are not shipping internationally at this time. We have had numerous problems with shipping companies and customs in regards to delivery time and fees, making it quite the headache for our customers (and ourselves).
I have a greenhouse with 6 foot high walls and I want to add 3 foot high hoops across the 12 foot width. Can your 12 foot bender make this hoop 12 feet wide and 3 feet high?
It would't be able to do this. Your angle on the hoop would be much different than what the hoop bender is designed for.
What is the heiight of a 12’ house? Will a 21’ x 1 3/8” pipe complete the arc using your 12’ bender?
The greenhouse would be 8 foot hight using a 12 foot hoop bender if you have 2 foot tall ground posts.
I am looking to make 30' green houses. can you make a bender for that?
We dont currently. Largest we have right now is 24'.
I purchased your 24' tube bender, what are the directions, or instructions for construction. More particular how many tubes will I need to make the 24' hoop.
