Foam: https://www.thefoamfactory.com/seatcushion/foamtypes.html

You want to use closed cell foam, if possible. Open cell foam can absorb water and fluids(yick).

Temporary Adhesive: 3m77 is the best overall adhesive to prevent movement. It is NOT a permanent adhesive. https://www.amazon.com/3M-77-Multipurpose-Adhesive-Aerosol/dp/B0000AZ735/ref=sr_1_3

Permanent adhesive: Barge cement or weldwood. Both are equally good. Many brands advertise different names, but it's repackaged barge or weldwood (you can get a 55 gal drum). It tends to be more rigid so its only suitable for adhesing to a solid base, like foam to wood or foam to metal. https://www.amazon.com/00271-Weldwood-Original-Contact-Cement/dp/B0006MXRY8/ref=pd_lpo_vtph_200_lp_t_3

Upholstery leather: While Tandy is the cheapest source, they generally sell second quality hides that are factory overruns or seconds. A better source is either the Carroll Leather company or the Hide House. Both are excellent. You want a fully protected corrected grain hide in the 3-4 oz range. The hide should be a full hide, not half, which is approximately 55 sqft. Both companies will sell you a single hide. Estimate about $8 sqft, including shipping. My preference is the Carroll Leather company because they have a better online catalog, but both companies will send you samples if you ask nicely. Both are excellent reputable companies. http://www.carrollleather.com/colours

Also, if you plan to stuff any enclosed leather items, like pillows, you will need spray silicone to ease the stuffing. http://www.upholsterysupplyonline.com/products/Pro-Slip-Dry-Silicone-Spray-Case-Of-12.html

You might need some upholstery tacks and a tack hammer. https://www.vandykes.com/upholstery-tacks-nails-tools/c/1696/

Alternatively a good staple gun works well. Do not use the electric ones. They're expensive and usually don't work as well as the manual ones https://www.amazon.com/Arrow-Fastener-T50-Heavy-Staple/dp/B00002ND61/ref=sr_1_4

For random hardware, try https://ohiotravelbag.com/ and https://www.buckleguy.com/The company behind buckleguy makes the hardware for Coach bags, so it is usually superior quality.

If you sew anything, use polyester thread, NOT nylon. Nylon absorbs water, and breaks down under exposure to UV. Polyester is what the boat upholstery guys use because it stands up over time.

Pro tip: expect to use twice as much leather as you think. It takes a lot of experience to correctly judge upholstery dimensions and usage. Also, pull the leather tighter than you think. Go slow, measure twice, cut once, and realize that leather stretches in two directions.

Edit: Marine vinyl is a good substitution for leather. It's non porous, and easily cleaned. Fabric is measured by the yard, which means the width of the roll (usually 54") x 1 yard long. Quality vinyl is ~$10-$20 per yard, which is about 1/4 the cost of quality leather. https://www.joann.com/marine-vinyl/prd23669.html or https://fabricwarehouse.com/discount-marine-vinyl-fabrics/

Very simply: Use the posts for modular wire shelving. The legs can screw together, each is 14 inches long.

These shelving systems are sold everywhere under many different names with the same basic design. Smaller shelves have legs that are 3/4" in diameter with 1/4" screws. Larger ones are available with 1" diameter posts and 1/2" screws connecting them. Different post lengths are available but 14" is the sweet spot for a spreader bar.

The cheapest option I found was the "Whitmor Supreme Stacking Shelf Organizer" on Amazon. This has 4x 14" posts that are 3/4" in diameter for $12.65+shipping: https://www.amazon.com/Whitmor-Supreme-Stacking-Shelf-Organizer/dp/B0007MHD2E/

You can also buy just a set of the 1" posts here: https://www.shelving.com/SI-Chrome-Round-Post-Sets-p/si-pc-set-p.htm (Note that I haven't bought from there, I just googled it when looking for the cheapest option).

There are also tons more options that are basically the same overall design. I'm not trying to endorse any vendor (I'm not affiliated with any of them), just pointing out that these very common posts are perfect for turning into a spreader bar.

A pack of two 1/4" 20 threads per inch (TPI) 2 1/2" long eye bolts are available from Home Depot for $1.18 and they fit the Whitmor posts perfectly. You can easily screw them in by hand at the ends and in less than a minute you have a spreader bar with no tools necessary.

I bought two sets of two eye bolts, so I could use one post as a wrist bar, and the remaining three legs combine to form a 42" leg spreader bar as pictured.

The best part of this is that you can unscrew the legs again, collapsing the bar for storage to a length of only about 15" (with the end eye bolts in). This means that instead of having an awkward 3+ foot bar in my closet I can easily throw the set of 15" posts in a large desk drawer (though they are still long enough I have to put them in at an angle to make them fit).

One concern at first glance might be: "Wait, if the posts screw together so easily couldn't someone just easily unscrew them and get out of the spreader?" Answer: No. Maybe this is obvious to people who are not me, but it doesn't work this way provided you are attached to both the screw and what it is attached to. Take any two things that are screwed together. Then try to unscrew one from the other, never taking your hand off of either one. Go ahead and try. You can't do it. You'll end up trying to wrap your arms into a pretzel. Despite how easily it screws together, it's secure.

Yeah, that is what it is :) https://www.amazon.ca/gp/product/B000BDD83M/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 Had my girlfriend sew a piece of fabric together to make the fit a bit tighter. It's removable so makes it easy to clean. As for the wand, I have it plugged into this timer( https://www.amazon.ca/gp/product/B0184CG9K0/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 ) so that I can have it turn on and then off for a little bit... over and over again. She found the magic wand a bit too strong so I also added an inline fan speed controler to lower the speed a bit ( https://www.amazon.ca/gp/product/B01MXQG4UZ/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 )

I don't know any video series, but this is the book series I recommend to new makers:

Fundamentals:

Make Electronics

Useful Companion Reference:

Encyclopedia of Electronic Components Volume 1

Encyclopedia of Electronic Components Volume 2

Bonus Points Reference:

Encyclopedia of Electronic Components Volume 3

Between those books and YouTube you'll be squared away for 99% of anything you would typically build at home. I say that as an engineer with work experience designing electronics.

I'd start by getting three reciprocating saws and the attachments for them for dildos and the fleshlight. then attaching them to.said frame via a mount.

you'll need basic welding skills, but I think the best place to start is a workout bench to support your torso then build the rest out from that base.

http://www.amazon.com/Prop-Builders-Molding-Casting-Handbook/dp/1558701281

It sounds like you may have molding and casting experience... and maybe you even have this book, but if you don't, it's not expensive and I think you'd find it helpful... materials-wise it's a bit outdated BUT I still find that when I'm about to do a new project, even with newer plastics, referencing it still tweaks my brain in ways that help solve problems before I get to them... perhaps you would also find it inspirational.

A flexible curve, available at any art supply store or Amazon, would be helpful in measuring your specific partner's wrists and ankles and transferring the dimensions to the wood.

This is pretty straight forward. The local dungeon had something similar but the gal at the counter didn't know what it was called. After a bit of research, I found it was a palm sap. This is strictly for HEAVY impact play, for use on large muscles, such as the rump. Do NOT use this on bone or unprotected areas. If you don't know what I'm talking about, stop here and consult someone more experienced, preferably at your local dungeon.

Made from suede leather, folded and sewn. The hand strap is nylon webbing and velcro, with the hook portion facing outward. It's filled with a pound of lead shot (from a diving weight bag from Amazon).
Bag is triple stitched along edges. Bag itself is 3 1/2" square and sewn with T69 nylon thread.

http://www.amazon.com/gp/product/B0013HUHMA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 is the weight bag I got. $14 for three pounds of shot, enough to do 3 saps.

If I were doing it again, I'd probably go with 12 ounces of shot.

If the contact cement will hold it there shouldnt be any shifting.

I use 5 min 2 part epoxy for most of the work amazon link. You can find at most big box stores as well. Its probably overkill but it works well and holds for ever (at least I have never had a flogger fail when using it).

(I also tend to have a tube or two laying around in the wood shop for various projects I end up using epoxy on)

came here to say this. get yourself a big red key for use in emergencies so you can still use mini-padlocks with peace of mind and without ruining the aesthetic.

I found these and they seem perfect.

MAGARROW 65" × 1.5" Utility Straps with Buckle Adjustable, 4-Pack (Black 9.5 feet Long (4-PCS)) https://www.amazon.com/dp/B07VQ1B3QN/ref=cm_sw_r_cp_apa_i_YqWUDbG02GRWF

The only reasonable solution is a fish mobile.

The one that comes up when you Google Juice electricity

Just had to be a little snarky

Juice: Electricity for Pleasure and Pain https://www.amazon.com/dp/1890159069/ref=cm_sw_r_cp_apa_i_F-7vCb4SZB9W3

Next time, get one of these. Wands, both violet and magic, need to be properly stepped down for safety reasons. Also you can get one for like $70 here. Their other stuff is overpriced a bit but the wand itself is legit and not super high priced.
