Hello gang! I'm still very new to most of this, but I've been following the builds closely and have taken many, many notes. I think I'm almost ready to try my hand, with a little help.
I searched high and low on the bench section, but as it's fairly new I couldn't find anything on how to make the airhoses that compress the lams/glass in the forms. Is there an easy way to make them? I've got a compressor and access to a fair amount of tooling, but I was wondering if there is any kind of instruction on making them
Thanks everyone for your help, and fantastic builds everyone!

All depends on expenses and accessible materials. The most simple way - to take a fire hose 2" and to make two fuses - continuous and with a nipple. It is possible to make fuses of dense wood, a nipple to use from the automobile or bicycle chamber. Fuses to paste and pull together collars. For the bows I use such hose. Good luck!

Binghams projects carries the complete air hose set up.

I went by a company that sells fire hoses and got some scraps they couldn't sell at full price. Picked up this part, a cap, a air valve and used high temp sealer and hose clamps.Tapped the air valve into the cap and put everything together-I've been using this set up for years now- no problems.

Plugs are 18.00 each from Binghams. Be hard to make your own for less then that. Chad

It is quite possible to make a nipple independently. So my variant looks.

Thanks so much for the help gang, I didn't see that Bingham had them.

I made mine out of some scrap brass stock and a piece of 1-1/2" fire hose we had to throw away (the mice chewed holes in it). I have access to a big lathe and hollowed the brass stock out to reduce weight and then installed a screw in valve stem in one. Works great and cost me a total of $4.50 for the valve and two hose clamps.

I made my own also with parts from the hardwear store and a steal valve stem from a semi rim and i stoped by my local vol. fire department and they happend to have a 30 foot peice of 2in hose they had replace with new and just gave the hose away. The hose looks fine to me.
-
I got my hose from the local Vol FD, quick trip to the hardware store and got plugs like pictured above and at first used the reg tire air fittings. Then one time I had one hose leak pressure during baking. Don't know when in the baking the pressure was lost but the limb never did fail. But I've since just installed a quick connect fitting so my air hose stays connected to my compressor during baking by notching my oven top to accomade the hose coming through.
-
Any specific pressure the hose should be held at? My compressor has a regulator on it, the last thing I'd want to do is pressurize the system to 110psi when I only need around 40psi.
-
I put 60psi my hose.
-
I blow mine up to 80 psi. bob

Here is mine:

One simple cork and one that have a tin truck valve
Made from scrap. The cork have two channels 3 mm dipper than outside surface and +2 mm width than necklace width. I check that this two cork to enter in the hose with a little pressure. I put some rubber adhesive inside of the hose and inserted the corks. Adhesive work first as a lubricant. When you put the necklace it squish the adhesive and fill any remaining hollows. Tested at 5 bar.
