Pyrex Bake A Round Tube Mounting Help
Hi Everyone,

I am new to the forum and am looking for some help on building a fluidbed roaster. My question is regarding the best way to create a mount for the Bake A Round tube. I have seem some using long threaded rods secured with nuts and two flat metal plates to hold it all together. and others using a martini shaker upside down with what looks to be high temperature silicone as a gasket.

Essentially I am looking to see if there are any off the shelf parts that would allow for a secure mount and any other feedback on a simple way to execute this. I have looked through all of the threads and have not seen anyone address the assembly directly.

EDIT: I am planning on using a Harbor Freight aluminum body heatgun with an extension tube to connect to the Bake Around. I will be attaching a shop vac to the air intake similar to the build on here with the exhaust splitter and two of the same heat guns. I have everything else in the build figured out, I am just looking for help with a simple housing that doesn't require complicated fabrication or tools for pyrex tube housing and that will be secure and account for expansion of the tube/mounting materials.

Thanks in Advance!

Literally the first thread I clicked on... haha. Looks like they use a v-flange and silicone around the tube.

Link for the v-flange
3" looks like It has an OD of 3.125" I think the ID of the bake-a-round is something like 3.25. Looks like about that gap in the pics in the thread I linked.

Also to be honest, you could do a lot with a drill, a hacksaw a sheet of thin stainless and some all-thread for the sandwich method. I would definitely not place that in the "complicated fabrication" category. Tools and materials could be had for under $100. (Walmart corded drill)
Thanks a Lot pisanoal, super helpful! Not sure how I missed that post!!

Hmm... what about the different heating coefficients of glass and steel ?
Know this video ? Grin
Look at 9:43...

Always a concern. Just need to make sure nothing fits too tight, and fill the gaps with a silicone gasket for expansion.
I used stove gasket rope and high temp RTV copper silicone to secure a metal funnel to the bottom of my bakearound as well as the same silicone to seat the perf plate into the funnel.

After at least a hundred roasts if not more like 2-300 no warps, cracks, visible ware on the silicone, funnel, or pyrex.
